Relationship between Ankyloglossia and Breastfeeding: A Bibliometric Review

ABSTRACT Objective: To assess global trends in the publication of studies investigating the association between ankyloglossia and breastfeeding. Material and Methods: An electronic search was performed in the Scopus database without restrictions. Observational studies and clinical trials were included. Bibliometric indices such as publication year, authors, co-authors, journals, field of knowledge, countries, and the most cited keywords were analyzed using the VOSviewer program. Results: The search retrieved 350 studies, and 68 were selected. The first article was published in 2000 in the United States. The United States presented the highest number of publications (n=21), followed by Brazil (n=9) and the United Kingdom (n=9). An increase in publications on this theme was observed in 2013; 2021 was the year with the highest number of publications (n=14). The most common word was "frenulum". The authors with the highest number of publications were Botze and Dollbert from Israel (n=3), Ghaheri, and Mace from the United States (n=3). Among the journals, "Breastfeeding Medicine" presented the highest number of publications (n=7), followed by the "International Journal of Pediatric Otorhinolaryngology" (n=6), "CODAS" (n=5), "Journal of Human Lactation" (n=4) and "Pediatrics" (n=3); the latter published the top-cited studies, with 412 citations. Conclusion: There has been an increase in recent articles evaluating the correlation between ankyloglossia and breastfeeding, indicating the growing interest of researchers in this field.

Introduction: High-power laser therapy has established satisfactory proportions in dentistry and has become the first choice for surgical procedures, bringing quality of life to patients and convenience to surgeons. Objective: To report a clinical case of lingual frenectomy using high-power diode laser, highlighting the benefits of this approach. Case report: A female patient, leucoderma, without systemic alterations, arrived at the Dental School Clinic of the Federal University of Campina Grande with the main complaint of alterations in her phonology. In the intraoral examination, difficulty in lingual movement and a heart-shaped tongue due to fibrous insertion of the frenum were observed, indicating Ankyloglossia. After explanations of the condition, treatment, and signing of the Informed Consent Form, the surgery was initiated: antisepsis, anesthesia with vasoconstrictor, and continuous mode using a high-power diode laser configured at 2W of power, 600µm fiber, at an infrared wavelength, with the aim of uniformly separating the fibers and promoting immediate tongue mobility. Finally, a simple suture was performed using absorbable thread. For the postoperative period, Dipyrone was prescribed for pain relief, and follow-up was established. At the 7-day follow-up, normal healing was observed, and the patient did not require the medication. At 30 days, complete healing and discomfort-free mobility were observed, along with the patient's testimony of improvement in social relationships, self-esteem, and swallowing. Conclusion: The results presented in this article confirm the benefits of choosing laser therapy over conventional methods, demonstrating the absence of bleeding during and after surgery, promoting tissue repair, reducing surgical time, increasing comfort, and decreasing the use of medication. Therefore, the use of surgical laser is associated with an improvement in quality of life.

Dysfunctional suction dynamics in newborns with ankyloglossia / Dinâmica de sucção disfuncional em recém-nascidos com anquiloglossia

ABSTRACT Purpose Compare infant suction in babies with and without ankyloglossia using a microprocessor-controlled pressure sensor coupled to a pacifier. Methods Fifty-five infants from 0 to 2 months of age underwent clinical examination for ankyloglossia, after which they were offered a silicone pacifier connected to the pressure acquisition device and suction activity was recorded. Thus, we extracted the frequency of sucks within a burst, the average suck duration, the burst duration, the number of sucks per burst, the maximum amplitude of sucks per burst and the inter-burst interval. Results The key difference in newborns with ankyloglossia in relation to control was that they perform longer bursts of suction activity. Conclusion The longer burst durations are likely a compensatory strategy and may underlie the pain reported by mothers during breastfeeding. We therefore propose a method for objectively quantifying some parameters of infant suction capacity and demonstrate its use in assisting the evaluation of ankyloglossia.

RESUMO Objetivo Comparar a sucção infantil em bebês com e sem anquiloglossia usando um sensor de pressão controlado por microprocessador acoplado a uma chupeta. Método Cinquenta e cinco lactentes de 0 a 2 meses de idade foram submetidos ao exame clínico de anquiloglossia, em seguida foi oferecido uma chupeta de silicone conectada ao dispositivo de aquisição de pressão e a atividade de sucção foi registrada. Assim, obtivemos dados sobre a frequência de sucções dentro de um período de sucções, a duração média da sucção, a duração da rajada, o número de sucções por rajada, a amplitude máxima das sucções por rajada e o intervalo entre rajadas. O teste t não pareado foi utilizado para comparações entre os grupos. Resultados A principal diferença dos recém-nascidos com anquiloglossia em relação aos do grupo controle é que eles realizam rajadas mais longas durante a atividade de sucção. Conclusão A duração mais longa das rajadas é provavelmente uma estratégia compensatória e pode estar por trás da dor relatada pelas mães durante a amamentação. Portanto, propomos um método para quantificar objetivamente alguns parâmetros da sucção infantil e demonstramos seu uso para auxiliar na avaliação da anquiloglossia.

Ligadura de la arteria lingual: estrategia para hemorragias por lesión de la arteria en la base de la lengua: informe de dos casos / Lingual Artery Ligation: Strategy for Bleeding from Artery Injury at the Base of the Tongue: Report of Two Cases

La hemorragia producida por lesión de la arteria lingual en la base de la lengua por cirugías o por tumores es infrecuente. La mayor frecuencia en la indicación de abordajes transorales para tratar diferentes patologías que afectan la orofaringe requiere que el equipo quirúrgico tenga experiencia en el manejo de esta complicación. La ligadura de la arteria lingual en el cuello es una técnica quirúrgica muy eficaz para solucionar la hemorragia, pero es importante conocer las posibles variantes anatómicas que puede tener la arteria en su trayecto cervical. Debido a su baja incidencia se propone como objetivo describir dos casos clínicos de pacientes que tuvieron hemorragias graves por lesión de la arteria lingual en la base de la lengua, producidas por daño quirúrgico y por erosión por tumor. [AU]

The bleeding caused by injury to the lingual artery at the base of the tongue due to surgery or tumors is infrequent. The increased frequency in the indication of transoral approaches to treat different pathologies affecting the oropharynx requires the surgical team to have experience in managing this complication. Ligation of the lingual artery in the neck is a very effective surgical technique to solve the bleeding; however, it is essential to be aware of the possible anatomical variants the artery may have in its cervical trajectory. Due to its low incidence, we propose to describe two clinical cases of patients who had severe bleeding due to a lesion of the lingual artery at the base of the tongue, produced by surgical damage and erosion due to a tumor.

Research progress of autologous graft technique for treating ureteral strictures / 中华泌尿外科杂志

For a long time, urological surgeons have been troubled by the treatment of long proximal and mid ureteral stricture, and the commonly used ileal ureteral substitution and autotransplantation have certain shortcomings. In recent years, the development of autologous graft technique has brought a new hope for these patients. The commonly used autologous grafts or flaps include oral mucosa, intestinal tissue, urogenital tissue, etc. The feasibility and safety of autologous graft technique have been preliminarily verified, but each kind of graft or flap has different advantages and disadvantages. The research progress of autologous grafts or flaps ureteroplasty in this article was reviewed and the related problems of this technique were discussed.

Analysis of the diagnosis and treatment of 68 cases of iatrogenic ureteral stricture / 现代泌尿外科杂志

【Objective】 To investigate the common etiology, characteristics and treatment of iatrogenic ureteral stricture. 【Methods】 The clinical data of 226 patients with ureteral stricture repaired during May 2019 and Mar. 2022 were retrospectively analyzed, including 68 cases of iatrogenic ureteral stricture. According to the etiology, the patients were divided into urinary group and non-urinary group. 【Results】 There were 42 females and 26 males, aged 25 to 67 (average 49.0±10.4) years. Upper ureteral stricture was detected in 24 (35.3%) cases, who received oral mucosal repair of the ureter. Middle ureteral stricture was detected in 12 (17.6%) cases, who underwent ileal ureterography. Lower ureteral stricture was observed in 24 (35.3%) cases, who were treated with vesical wall flap ureteroplasty. Full-length stricture was observed in 8 (11.8%) cases,who were treated with ileal ureterography. There were significant differences in age, gender, stenosis side, stenosis location and length, surgical methods and types between patients in the urinary group and non-urinary group (P<0.05). During the follow-up of 8 to 20 (average 12.3±5.6) months, the symptoms and renal function of all patients improved, and no recurrence occurred. 【Conclusion】 Invasive endourological surgery is the most common cause of iatrogenic ureteral stenosis. Different treatment strategies should be adopted according to patients’ condition, time of diagnosis and location and length of ureteral injury.

Treatment of urinary calculi after lingual mucosal ureteral reconstruction: a case report / 中华泌尿外科杂志

Ureteral calculi after lingual mucosal ureteral reconstruction are rare. In this paper, we reported a case of a male patient who had undergone robotic-assisted laparoscopic lingual mucosal right ureteroplasty. Calculi were found in the right reconstructed ureteral segment 4 months after surgery. Then the patient underwent transurethral ureteroscopic holmium laser lithotripsy combined with a stone retrieval basket, and postoperative urological CT showed no residual calculi in the right ureter. No recurrence of right ureteral calculi or complications were observed during 20 months of follow-up.

Research progress on "sandwich" osteotomy to increase alveolar bone / 口腔疾病防治

@#Lack of alveolar bone height is a major challenge for dental implants. In recent years, the use of "sandwich" osteotomy to increase alveolar bone height has become a topic of discussion within the research community. In theory, "sandwich" osteotomy is a U-shaped osteotomy in the bone defect area, to preserve the blood supply of the mucoperiosteal on the lingual side and to create an artificial "four-wall bone bag" to build a favorable space for osteogenesis and to increase the height of the alveolar bone. Histological studies have shown that the osteogenesis speed of "sandwich" osteotomy is fast, and the bone is good. Sandwich osteotomy is suitable for buccal-lingual alveolar bone height defects less than 50% of the implant length or for unilateral defects more than 50% of the implant length. In the operation of "sandwich" osteotomy, the horizonal incision should be 10-12 mm below the crest of the buccal alveolar ridge. The design of the osteotomy line should ensure the height of the osteotomy block and that the mandibular canal does not sustain damage and that it fits the shape of the bone defect. There was no significant difference in the osteogenic effect of different types of bone graft materials used for "sandwich" osteotomy. The osteotomy block was rigorously fixed by a titanium plate, titanium nail, implant and other materials, and finally, the intraoperative area was tensioned and sutured. The effect of bone augmentation was evaluated and compared with other bone augmentation techniques; the evaluation showed that sandwich osteotomy was better for moderate vertical bone defects. This technique is highly sensitive and postoperative transient sensory loss is common. With advances in technology, the application of digital technology and ultrasonic bone knives, the risk of complications is greatly reduced and advances in digital osteotomy will promote apply of "sandwich" osteotomy, which will become a popularized technique for clinical alveolar bone augmentation.

Effect of lingual frenotomy on the breastfeeding improvement

To evaluate breastfeeding in babies up to six months of age before and after frenotomy surgery in a reference hospital in a city from Santa Catarina state. Methods: An observational quality improvement study, carried out with babies up to six months of age undergoing frenotomy and their mothers in a reference hospital in southern Santa Catarina state. A questionnaire was applied to the mothers in two moments (before and after the surgery), with information regarding breastfeeding, sociodemographic, anthropometric and behavioral characteristics of them and of the babies. Descriptive analyzes were performed and the association between breastfeeding and the independent variables was assessed through Pearson's chi-square and Fisher's exact tests, using a 5% significance level. Results: A total of 74 children were studied, with 48 of them returning after surgery. 83.8% were breastfed before surgery and 64.9% after surgery. Before surgery, 58.1% of children effectively took the breast at once. After surgery, this prevalence was 83.3% (p=0.015). Before surgery, 75.9% of the mothers reported not feeling pain, while, after surgery, almost all of them (95.8%) reported this (p=0.004). Most mothers reported improvement in grip (83.3%), increase in the duration of breastfeeding (69.0%), improvement of baby's breathing (75.0%), and an increase in the frequency of breastfeeding (51.7%). Conclusions: There was a decrease in the prevalence of breastfeeding after frenotomy. However, there was an improvement in the babies 'grip and breathing and a reduction in the mothers' pain when breastfeeding. It is emphasized the need to implement multidisciplinary actions in both primary and hospital care to assist mothers in order to prolong the duration of exclusive breastfeeding

Effects of lingual frenotomy on breastfeeding and electrical activity of the masseter and suprahyoid muscles / Efeito da frenotomia lingual na amamentação e na atividade elétrica dos músculos masseter e supra-hióideos

ABSTRACT Purpose To analyze the effects of lingual frenotomy on the breastfeeding of infants, based on the electrical activity of the masseter and suprahyoid muscles and assessment of the breastfeeding. Methods Observational study developed between October 2017 and June 2018 with a sample of 20 newborns and infants who attended a dental clinic and were diagnosed with ankyloglossia. Another 20 were excluded for meeting some of the following exclusion criteria: babies more than 6 months old, who were not on exclusive or mixed breastfeeding, who had other clinical impairments that interfered with breastfeeding, who had other foods introduced into their diet, who had neurological changes and/or craniofacial deformities, and/or who did not finish all the stages of the study. Breastfeeding was assessed with the UNICEF Breastfeeding Assessment and Observation Protocol, while the muscle electrical activity was assessed with the Electrical Activity Assessment Protocol for the Masseter and Suprahyoid Muscles in Newborns During Breastfeeding. The same speech-language-hearing therapist conducted the two assessments both before the conventional frenotomy and 7 days after it. Results The signs suggestive of breastfeeding difficulties changed 7 days after the surgery, with a p-value ≤ 0.002 for general observation of the mother, position of the infant, latch, and sucking. The maximum voluntary contraction of the masseter was the only integral parameter with a difference, as the electrical activity had decreased. Conclusion Behaviors favorable to breastfeeding increased 7 days after the frenotomy in all the breastfeeding assessment categories, whereas the electrical activity of the masseter decreased.

RESUMO Objetivo Analisar os efeitos da frenotomia lingual na amamentação de recém-nascidos, com base na atividade elétrica dos músculos masseter e supra-hióideos e avaliação da mamada. Método Estudo observacional, desenvolvido entre outubro de 2017 e junho de 2018. Amostra de 20 recém-nascidos e lactentes de uma clínica odontológica, diagnosticados com anquiloglossia; 20 foram excluídos por se encaixarem em algum dos critérios de exclusão: ter mais de seis meses de vida, não fazer aleitamento materno exclusivo ou misto, apresentar outro comprometimento clínico que interfira na amamentação, ter iniciado a ingestão de outros alimentos, alterações neurológicas e/ou deformidades craniofaciais e não ter finalizado todas as etapas do estudo. A avaliação da amamentação seguiu o Protocolo de Observação e Avaliação da Mamada da UNICEF, e a avaliação da atividade elétrica muscular o Protocolo de Avaliação da Atividade Elétrica dos Músculos Masseter e Supra-hióideos em Recém-Nascidos Durante a Alimentação, ambas realizadas pela mesma fonoaudióloga antes da frenotomia convencional e sete dias após. Resultados Os sinais sugestivos de dificuldade na amamentação mudaram sete dias após a cirurgia, com valor de p≤0,002 para a observação geral da mãe, posição do bebê, pega e sucção. Houve diferença apenas no parâmetro integral da Contração Voluntária Máxima do masseter, com diminuição da atividade elétrica. Conclusão Sete dias após a frenotomia observou-se aumento de comportamentos favoráveis ​​à amamentação em todas as categorias de avaliação da mamada e diminuição da atividade elétrica do masseter.

Análise quantitativa de frenectomias realizadas no contexto do SUS após obrigatoriedade do teste da linguinha / Quantitative analysis of frenectomies performed in the context of the SUS after mandatory tongue test

RESUMO Buscou-se investigar e conhecer a frequência e a distribuição de frenotomias e fenectomias realizadas no Sistema Único de Saúde (SUS) após os dispositivos legais que instituíram o teste da linguinha, bem como entender quais profissionais estão realizando o procedimento cirúrgico. Estudo descritivo analítico, retrospectivo, com dados secundários, disponíveis no Sistema de Informações Ambulatoriais do DataSUS, extraídos por meio do TabWin. Observou-se um aumento considerável no número de procedimentos, porém, com flutuações nos anos seguintes. Das frenectomias registradas no SUS, no período, 33% foram realizadas por dentistas na atenção primária. Os resultados apontaram que houve um aumento substancial no número de procedimentos cirúrgicos em dois momentos, em 2014 e em 2017, possivelmente em decorrência da publicação da Lei nº 13.002/2014 e da Nota Técnica (NT) nº 09/2016. A NT nº 35/2018 deslocou o diagnóstico e o tratamento para a média complexidade, possivelmente resultando em filas, principalmente em se tratando de cirurgias que poderiam ser realizadas na atenção primária. Apesar de não haver unanimidade quanto à correlação anquiloglossia e desmame, não parece haver um monitoramento para evitar cirurgias desnecessárias, uma vez que a ordenha pode não ser afetada e o acompanhamento ser realizado para confirmar ou não essa necessidade.

ABSTRACT This study sought to investigate and to know the frequency and the distribution of frenotomies and frenectomies performed in the Unified Health System (SUS) after the legal provisions that instituted the tong test, and to understand which professionals are performing the surgical procedure. This is an analytical, descriptive, retrospective study, with secondary data, available in the DATASUS Information System. It was observed that a considerable increase in the number of procedures, but with fluctuations in the following years. Out of the frenectomies registered in the SUS in the period, 33% were performed by dentists in primary care. The results showed that there was a substantial increase in the number of surgical procedures in two moments, in 2014 and in 2017, possibly as a result of the publication of Ordinance nº 13.002/2014 and Technical Note (NT) No. 09/2016. NT No. 35/2018 shifted diagnosis and treatment to medium complexity, possibly resulting in queues, especially in the case of surgeries that could be performed in primary care. Although there is no unanimity regarding the correlation between ankyloglossia and weaning, there seems to be no monitoring to avoid unnecessary surgeries, since milking may not be affected and follow-up is carried out to confirm or not this need.

Anquiloglossia e alterações na fala: revisão integrativa da literatura / Ankyloglossia and speech disorders: integrative literature / Revieanquiloglosia y trastornos del habla: revisión integradora de la literatura

Objetivo: Caracterizar as alterações na fala decorrentes da anquiloglossia, por meio de revisão integrativa da literatura. Métodos e Procedimentos: Levantamento bibliográfico realizado em fevereiro de 2020, delimitado segundo os idiomas inglês, português, espanhol e idade a partir de 6 anos. Foram selecionados artigos disponíveis em quatro bases eletrônicas: PubMed, SciELO, Scopus, Web Of Science. Palavras-chave utilizadas: freio lingual; distúrbios na fala; anquiloglossia. Foram consideradas publicações de 2010 a 2020 mediante análise de metadados, a partir do título e resumo, para identificar pertinência à pesquisa. Foram excluídos estudos publicados há mais de dez anos, que não permitiram acesso ao texto integral, repetidos por sobreposição dos descritores, discrepantes do tema. Resultados e Discussão: Foram localizados 276 artigos, que após aplicados os critérios de inclusão e exclusão resultaram em 27. Os resultados encontrados indicam que sujeitos com alterações no frênulo lingual, principalmente na anquiloglossia, utilizam estratégias compensatórias variadas de lábios, língua e mandíbula para a produção dos fonemas 't', 'd', 'l', 'n', 's', 'z', 'r' e de grupos consonantais, que poderão apresentar distorção, substituição e/ou omissão, por serem de difícil produção com frênulo curto. Aos profissionais otorrinolaringologistas, ortodontistas e fonoaudiólogos é recomendada realização de exame clínico cuidadoso, que possibilite diagnóstico com objetivo de obter resultados satisfatórios em menor tempo e indicação de intervenções cirúrgicas, quando necessárias. Conclusão: A revisão integrativa da literatura aponta para a relação entre anquiloglossia e alterações na fala.

Objective: To characterize the speech disorders resulting from ankyloglossia, through an integrative literature review. Methods and Procedures: Bibliographic survey carried out in February 2020, delimited language (English, Portuguese, Spanish) and age (from 6 years old). Articles available in four electronic databases were selected: PubMed, SciELO, Scopus, Web of Science. Keywords used: lingual frenum; speech disorders; ankyloglossia. Manuscripts published from 2010 to 2020 were included based on metadata analysis that considered title and abstract to identify the relevance for this research. Studies published over ten years ago, those that did not allow access to the full text, manuscripts repeated due to overlapping of descriptors or diverging from the topic were excluded. Results and Discussion: 276 articles were initially identified; after the inclusion and exclusion criteria were applied, 27 studies were considered. The results showed that subjects with lingual frenulum alterations, mainly ankyloglossia, use varied compensatory strategies of lips, tongue and mandible for the production of the phonemes 't', 'd', 'l', 'n', 's', 'z', 'r' and consonant clusters, which may present distortion, substitution and/or omission, as their production is hindered by the short frenulum. Otorhinolaryngologists, orthodontists and speech therapists are recommended to conduct careful clinical examination, allowing for diagnosis, in order to obtain satisfactory results in less time and indication of surgical interventions, when necessary. Conclusion: The integrative literature review shows the relationship between ankyloglossia and speech disorders

Métodos y Procedimientos: Encuesta bibliográfica realizada en febrero de 2020, delimitada según inglés, portugués, español y edad a partir de 6 años. Bases de datos electrónicas seleccionadas: PubMed, SciELO, Scopus, Web Of Science. Palabras clave utilizadas: frenillo lingual; trastornos del habla; anquiloglosia. Las publicaciones de 2010 a 2020 se consideraron mediante análisis de metadatos, desde el título y el resumen. Se excluyeron los estudios publicados hace más de diez años, que no permitían el acceso al texto completo, repetidos por superposición de descriptores, discrepantes con el tema. Resultados y Discusión: Se localizaron 276 artículos, que luego de aplicar los criterios de inclusión y exclusión resultaron 27. Los resultados encontrados indican que los sujetos con alteraciones en el frenillo lingual, principalmente en anquiloglosia, utilizan variadas estrategias compensatorias de labios, lengua y mandíbula para la producción de los fonemas 't', 'd', 'l', 'n', 's', 'z', 'r' y grupos consonánticos, que pueden presentar distorsión, sustitución y/u omisión, porque son difíciles de producir con un frenillo corto. Se recomienda a los otorrinolaringólogos, ortodoncistas, logopedas profesionales que realicen examen clínico cuidadoso, que permita un diagnóstico con el objetivo de obtener resultados satisfactorios en menos tiempo e indicación de intervenciones quirúrgicas, cuando sea necesario. Conclusión: La revisión integrativa de la literatura apunta a la relación entre la anquiloglosia y los trastornos del habla.

Responsabilidade profissional por lesão do nervo lingual durante exodontia de terceiro molar inferior: análise de nove processos judiciais / Professional responsibility for lingual nerve injury during lower third molar extraction: analysis of nine court proceedings

Introdução: A remoção cirúrgica dos terceiros molares inferiores apresenta o risco potencial de lesões a estruturas nobres como o nervo lingual devido sua localização anatômica. O grau de comprometimento do nervo indicará se a lesão é transitória ou permanente. A injúria nervosa pode motivar o paciente a acionar judicialmente o cirurgião-dentista, e sendo evidenciada a culpa profissional, caberá a reparação pecuniária dos danos causados ao paciente, sejam de natureza material ou moral. Objetivo: Analisar nove decisões judiciais de 1ª e 2ª instância, disponíveis no site do Tribunal de Justiça de São Paulo (TJSP), motivadas pela lesão do nervo lingual durante a exodontia de terceiro molar inferior. Metodologia: Após a leitura e análise foram extraídas informações como: perfil das partes, tempo de duração dos processos, procedência ou não da ação, valor da indenização, responsabilidade profissional e presença de TCLE. Resultados: Na primeira instância, seis dos nove casos foram julgados improcedentes; em segunda instância, quatro destas sentenças foram reformadas para procedência. No total, após decisão de segunda instância, houve procedência da ação em sete dos nove casos. Nas ações procedentes, as indenizações para dano moral variaram de R$ 5 mil a R$ 50 mil, sendo a imperícia e negligência as modalidades de culpa mais atribuídas aos profissionais. Conclusão: Sabendo-se que a lesão do nervo lingual durante a extração de terceiro molar inferior, mesmo previsível, nem sempre é evitável, verifica-se a importância do TCLE (ou documento similar) na prática clínica como instrumento de defesa jurídica do profissional, diante da alegação de falha de informação. Este documento foi mencionado em apenas três dos nove casos processuais, sendo em que em dois destes não houve constatação de falha técnica ou de informação (ação improcedente nas duas instâncias)

Introduction: Surgical removal of lower third molars presents the potential risk of injury to noble structures such as the lingual nerve due to its anatomical location. The level of nerve involvement will indicate whether the injury is transient or permanent. Nervous injury can motivate the patient to sue the dentist, and if professional guilt is evidenced, it will be up to pecuniary compensation for the damage caused to the patient, whether of a material or moral nature. Objective: To analyze nine court decisions of 1st and 2nd instances, available on the Court of Justice of State of São Paulo (Brazil) website, motivated by lingual nerve injury during lower third molar extraction. Methodology: After reading and analysis, information was extracted such as: profile of the litigating parties, duration of the processes, judge decision for the action, indemnity value, professional responsibility and presence of TCLE. Results: In the first instance, six of the nine cases were dismissed, the sentence was reformed in four cases, confirming the merits of the action in seven of the nine cases. In the cases of valid actions, compensation for moral damages ranged from R$ 5 thousand to R$ 50 thousand, with malpractice and negligence being the types of fault most attributed to professionals. Conclusion: Knowing that lingual nerve injury during mandibular third molar extraction, even if predictable, is not always avoidable, the importance of the informed consent (or similar document) in clinical practice as an instrument for the professional's legal defense is mandatory, to avoid the allegation of miss information. This document was mentioned in only three of the nine cases, and in two of these there was no finding of technical or information failure (unfounded action in both instances)

Ortodoncia estética. Tratamientos híbridos o combinados: ortodoncia lingual y vestibular / Aesthetic orthodontics. Hybrid or combined treatments: lingual and vestibular orthodontics

La ortodoncia lingual ha acercado a la consulta ortodóncica a pacientes que nunca antes hubie- ran aceptado un tratamiento ortodóncico. Los tratamientos estéticos son una de las opciones más solicitadas en este siglo por los pacientes adultos, que no solo desean un resultado estético sino que solicitan, también, aparatología estética. Se presenta el caso de una paciente adulta para el que se eligió un tratamiento híbrido: aparatología superior lingual (brackets linguales 2D) y apara- tología inferior vestibular (brackets autoligables, prescripción Roth pasiva-activa). Los brackets 2D son de autoligado, por lo que se utilizan fuerzas biológicas, suaves, constantes y continuas. Es importante en estos casos que ambos maxilares se trabajen con el mismo tipo de fuerzas.

Lingual orthodontics has brought to the orthodontic consultation patients who would never have accepted orthodontic treatment before. In this century, aesthetic treatments are one of the most requested options by adult patients who not only want an aesthetic result but also aesthetic appliances. It is presented the case of an adult patient to which a hybrid treatment was chosen: upper lingual appliances (2D lingual brackets) and lower vestibular appliances (self-ligating brackets, passive-active Roth prescription). 2D brackets are self-ligating, so constant and continuous biological gentle forces are used. In these cases, it is important that both jaws are worked with the same type of forces.

SUMMARY: The aim of this study was to determine the morphologic characteristics of the lingual foramen and lateral lingual foramen using cone-beam CT in elderly Korean. Cone-beam CT images were obtained from 80 Korean older than 50 years (mean age, 65.2 years). The prevalence of the lingual and lateral lingual foramina at the lingual aspect of the mandible was determined. The diameter and height to the upper margin of the foramina from the mandibular inferior margin, and the bone height to the alveolar crest from the mandibular inferior margin were measured. In addition, the location of the lateral lingual foramen, the direction of its canal, and the presence of communication with the mandibular canal were evaluated. All of elderly Korean possessed at least one lingual foramen, with two or three foramina occurring in 77.5 % of Korean. A lateral lingual foramen was observed in 91.3 % of Korean, with the prevalence being highest at the second premolar in dentulous cases (21.6 %; 33/153). The very high frequencies of these foramina were attributable to high frequencies of relatively small-diameter inferior lingual foramen and lateral lingual foramen in the incisor region. The prevalence of a large-diameter (≥1 mm) superior lingual foramen was high, at 31.0 %. A large-diameter lateral lingual foramen in the premolar region occurred at a frequency of 17.0 %; communication with the mandibular canal was observed in 70.0 % of these cases. These quantitative data on the lingual and lateral lingual foramina of the mandible provide valuable information that could help to avoid surgical complications during implant placement in elderly Korean.

RESUMEN: El objetivo de este estudio fue determinar las características morfológicas del foramen lingual y del foramen lingual lateral mediante TC de haz cónico en adultos mayores coreanos. Se obtuvieron imágenes de TC de haz cónico de 80 coreanos mayores de 50 años (edad media, 65,2 años). Se determinó la prevalencia de los forámenes linguales y linguales laterales en la cara lingual de la mandíbula. Se midió el diámetro y la altura hasta el margen superior de los forámenes desde el margen inferior mandibular, y la altura ósea hasta la cresta alveolar desde el margen inferior mandibular. Además, se evaluó la ubicación del foramen lingual lateral, la dirección de su canal y la presencia de comunicación con el canal mandibular. Todos los adultos mayores coreanos tenían al menos un foramen lingual, con dos o tres forámenes en el 77,5 %. Se observó un foramen lingual lateral en el 91,3 %, siendo la prevalencia más alta en el segundo premolar en casos dentados (21,6 %; 33/ 153). Las mayores frecuencias de estos forámenes se atribuyeron a altas frecuencias de foramen lingual inferior y foramen lingual lateral de diámetro relativamente pequeño en la región de los incisivos. La prevalencia de un foramen lingual superior de gran diámetro (≥1 mm) fue alta, del 31,0 %. Un foramen lingual lateral de gran diámetro en la región premolar ocurrió con una frecuencia del 17,0 %; se observó comunicación con el canal mandibular en el 70,0 % de estos casos. Estos datos cuantitativos sobre los forámenes linguales y linguales laterales de la mandíbula proporcionan información valiosa que podría ayudar a evitar complicaciones quirúrgicas durante la colocación de implantes en adultos mayores coreanos.

Lengua vellosa negra en lactante

RESUMEN Introducción: La lengua vellosa negra es un trastorno benigno adquirido, de presentación inusual en pediatría. Consiste en una glositis benigna caracterizada por una hipertrofia de las papilas filiformes linguales, con aumento de su queratinización, lo cual condiciona que la superficie adquiera un aspecto velloso con un color que varía de pardo negruzco a negro, debido a la presencia de microorganismos productores de sustancias cromógenas. Objetivo: Describir las principales características de esta entidad y revisar los conceptos más actuales. Presentación del caso: Lactante de 10 meses que es llevado a consulta al notar la madre que el niño presentaba una lengua de color negro, con antecedentes de haber sido tratado con cefalexina debido a un impétigo contagioso 10 días antes. El examen físico mostró un aumento de volumen de las papilas filiformes linguales, posiblemente vinculada al uso del antibiótico, asociada a una defectuosa limpieza de la lengua. En el estudio microbiológico se aisló Cándida albicans, que se consideró como hallazgo concomitante. El tratamiento consistió en medidas de limpieza de la lengua con buena respuesta. Conclusiones: La lengua vellosa negra es una enfermedad autolimitada rara en lactantes, de diagnóstico clínico y buen pronóstico. El tratamiento debe ir encaminado al empleo de medidas higiénicas, como terapéutica de primera línea. El tratamiento antifúngico por lo general es innecesario. Hasta donde conocemos, este es el primer caso en Cuba, documentado en la literatura médica.

ABSTRACT Introduction: Black hairy tongue is an acquired benign disorder, of unusual presentation in pediatrics. It consists of a benign glossitis characterized by a hypertrophy of the lingual filiform papillae, with increased keratinization, which conditions that the surface acquires a hairy appearance with a color that varies from blackish brown to black, due to the presence of microorganisms that produce chromogenic substances. Objective: Describe the main characteristics of this entity and review the most current concepts. Case Presentation: A 10-month-old infant who is taken to the consultation when the mother notices that the child had a black tongue, with a history of having been treated with cephalexin due to a contagious impetigo 10 days before. Physical examination showed an increase in volume of the lingual filiform papillae, possibly linked to the use of the antibiotic, associated with a defective cleaning of the tongue. In the microbiological study, Candida albicans was isolated, which was considered as a concomitant finding. The treatment consisted of tongue cleaning measures with good response. Conclusions: Black hairy tongue is a rare self-limiting disease in infants, with a clinical diagnosis and a good prognosis. Treatment should be aimed at the use of hygienic measures, as first-line therapy. Antifungal treatment is usually unnecessary. As far as we know, this is the first case in Cuba, documented in the medical literature.

Does size of the cochlear nerve affect postoperative auditory performance in pediatric cochlear implant patients with normal cochlear nerves? / O tamanho do nervo coclear afeta o desempenho auditivo pós-operatório em pacientes pediátricos com implante coclear e nervos cocleares normais?

Abstract Introduction Cochlear implantation is an effective treatment method for severe to profound hearing loss. Many factors that may influence cochlear implantation success have been explained in previous studies. Apart from those, minor differences in size of normal cochlear nerves may affect postoperative performance. Objective To investigate whether the minor differences in cochlear nerve size in normal cochlear nerves affect postoperative cochlear implant performance. Methods 30 pediatric prelingually deaf patients who were treated with cochlear implantation were included in this study. From the reconstructed parasagittal magnetic resonance images, the diameter and cross-sectional area of the cochlear nerve on the ipsilateral and contralateral side were measured. Auditory evaluations were performed 1, 3, 6 and 12 months following the first fitting. All the analysis was performed by using EARS®, evaluation of auditory responses to speech tool. Correlation between cochlear nerve diameter, cross-sectional area and postoperative auditory perception was analyzed to determine whether variation in cochlear nerve size contributes to postoperative auditory performance. Results The mean diameter of the cochlear nerve on the ipsilateral side was 718.4 μm (504.5 − 904.3 μm) and mean cross sectional area was 0.015 cm2 (0.012 − 0.018 cm2). On the contralateral side the mean cochlear nerve diameter was 714.4 μm (502.6 − 951.4 μm) and mean cross sectional area was 0.014 cm2 (0.011 − 0.019 cm2). The correlation between the diameter and cross-sectional area of the ipsilateral and contralateral cochlear nerve revealed no significance. Mean score at first month monosyllable-trochee-polysyllable test, MTP1, was 0.17 (0.08 − 0.33), at 6th month with 6 words test, 6th month MTP6 was 0.72 (0.39 − 1.0), at 6th month with 12 words, 6th month MTP 12 was 0.46 (0.17 − 0.75) and at 12th month with 12 words, 12th month MTP12 was 0.73 (0.25 − 1.0). There was no correlation between the monosyllable-trochee-polysyllable test, values at any time with the diameter of the ipsilateral cochlear nerve. However, the first month MTP, 6th month MTP6 and 12th month MTP12 correlated with the cross-sectional area of the ipsilateral cochlear nerve. Conclusion Measuring the cross sectional area of the normal- appearing cochlear nerve may give important prognostic knowledge on cochlear implant outcomes. In patients with a larger cross sectional area the auditory performance was better and faster. Although normal appearing, slight differences on cross sectional area of the cochlear nerve may affect performance. Measuring the size of the cochlear nerve on parasagittal magnetic resonance images may provide beneficial information on the postoperative rehabilitation process.

Resumo Introdução O implante coclear é um método de tratamento eficaz para a perda auditiva grave a profunda. Muitos fatores que podem influenciar o sucesso do implante coclear foram explicados em estudos anteriores. Além desses fatores, pequenas diferenças no tamanho dos nervos cocleares normais podem afetar o desempenho pós-operatório. Objetivo Investigar se pequenas diferenças no tamanho dos nervos cocleares normais afetam o desempenho pós-operatório do implante coclear. Método Foram incluídos neste estudo 30 pacientes pediátricos surdos pré-linguais, tratados com implante coclear. A partir de imagens de ressonância magnética parassagitais reconstruídas, foram medidos o diâmetro e a área de seção transversal do nervo coclear no lado ipsilateral e contralateral. As avaliações auditivas foram feitas 1, 3, 6 e 12 meses após a primeira adaptação. Todas as análises foram feitas com a ferramenta EARS® (do inglês evaluation of auditory responses to speech). A correlação entre o diâmetro do nervo coclear, a área transversal e a percepção auditiva pós-operatória foi analisada para determinar se a variação no tamanho do nervo coclear contribui para o desempenho auditivo pós-operatório. Resultados O diâmetro médio do nervo coclear no lado ipsilateral foi de 718,4 μm (504,5 a 904,3 μm) e a área da seção transversal média foi de 0,015 cm2 (0,012-0,018 cm2). No lado contralateral, o diâmetro médio do nervo coclear foi de 714,4 μm (502,6 a 951,4 μm) e a área da seção transversal média foi de 0,014 cm2 (0,011 a 0,019 cm2). A correlação entre o diâmetro e a área transversal do nervo coclear ipsilateral e contralateral não revelou qualquer significância. O escore médio do teste monosyllable-trochee-polysyllable no primeiro mês, denominado MTP1, foi de 0,17 (0,08-0,33), no sexto mês com teste de 6 palavras, MTP6, foi de 0,72 (0,39-1,0), no sexto mês com 12 palavras, MTP12, foi de 0,46 (0,17-0,75) e no 12° mês com 12 palavras, MTP12, foi de 0,73 (0,25-1,0). Não houve correlação entre os valores do teste monosyllable-trochee-polysyllable em qualquer momento com o diâmetro do nervo coclear ipsilateral. Entretanto, o teste monosyllable-trochee-polysyllable do primeiro mês, do 6° mês, e o do 12° mês correlacionaram-se com a área transversal do nervo coclear ipsilateral. Conclusão Medir a área da secção transversal do nervo coclear de aparência normal pode fornecer conhecimento prognóstico importante sobre os resultados do implante coclear. Em pacientes com área da secção transversal maior, o desempenho auditivo foi melhor e mais rápido. Embora o nervo coclear pareça normal, pequenas diferenças na área da secção transversal do nervo coclear podem afetar o desempenho, de forma que a medida do tamanho do nervo coclear nas imagens de ressonância magnética na projeção parassagital pode fornecer informações benéficas sobre o processo de reabilitação pós-operatória.

Lingual tonsil hypertrophy: about a case of unpredictable difficult airway / Hipertrofia de la amígdala lingual: a propósito de un caso de vía aérea difícil imprevisible

Abstract: Eleven years old children, proposed for resection of pylocitic astrocytoma of cerebellum, presented with lingual tonsil hypertrophy causing a unpredictable difficult airway approach. The presence of a lingual tonsil hypertrophied isn't diagnosed most of the times, with their occurrence being associated with previous tonsillectomy in more than half of the cases. Its occurrence, and non-identification, can originate scenarios of difficult airway approach, with a higher morbility association.

Resumen: Niño con 11 años, propuesto para exéresis de recidiva de astrocitoma pilocítico del cerebelo con hipertrofia de las amígdalas linguales a condicionar vía aérea difícil no previsible. La hipertrofia de las amígdalas linguales es subdiagnosticada y se suele asociar a amigdalectomía previa en más de la mitad de los casos. Su ocurrencia y no reconocimiento, puede originar situaciones de vía aérea difícil, con alta morbilidad asociada.

Effect of Lingual Frenotomy on Tongue and Lip Rest Position: A Nonrandomized Clinical Trial

Abstract Introduction The tongue plays an important role in the development of craniofacial structures. At rest, the light and constant pressure of the tongue against the hard palate, counterbalanced by the pressure provided by proper lip sealing, serves as a guide for maxillary growth. Ankyloglossia makes tongue coupling against the hard palate difficult, impacting maxillary development, which may lead to breathing disorders. Objective To verify the effect of lingual frenotomy on the resting position of the tongue and lips in infants with ankyloglossia. Methods The sample consisted of 334 infants aged between 1 and 60 days old diagnosed with ankyloglossia. The groups were divided in: a) experimental group (EG), which consisted of infants whose mothers agreed with lingual frenotomy; b) control group (CG), which consisted of infants whose mothers either refused lingual frenotomy or were waiting for surgery. Both the position of the lips and of the tongue at rest were assessed while the infants were sleeping during the quiet sleep phase. For mothers who refused their infants to undergo the surgical procedure, a follow-up of the infants was proposed to verify possible interference of the frenulum with the resting position of the tongue and lips. Infants whose mothers agreed with surgery were referred for lingual frenotomy. Results Regarding the position of the tongue and lips at rest at the initial and final assessments, the statistical analysis demonstrated significant differences between both groups. Conclusion Lingual frenotomy enabled infants diagnosed with ankyloglossia to maintain both tongue coupling against the hard palate and closed lips at rest.
