Profile of Laryngeal Microsurgeries in Patients Over 60 Years Old

Abstract Introduction The increase in life expectancy is an incentive to the development of researches with the elderly population aiming at actions that may ensure healthy and active aging. Objective To analyze the profile of laryngeal microsurgery performed in patients > 60 years old. Methods A retrospective observational study, with a cross-sectional design. A retrospective analysis of the medical records of elderly patients submitted to laryngeal microsurgery was performed at a private hospital in Curitiba, state of Paraná, Brazil, between January 2004 and December 2016. Were included all of the patients > 60 years old that underwent laryngeal microsurgery during this period. Results During the studied period, 213 laryngeal microsurgeries were performed in 181 patients > 60 years old. There was a preponderance of male patients. The mean age was 67.6 years old. Squamous cell carcinoma (SCC) was the most prevalent disorder (26%), followed by Reinke edema (20%), papillomatosis (14%), polyps (11%), leukoplakia (8%), minor structural alterations (8%), associated lesions (9%), and others (4%). Men presented a higher probability of SCC diagnosis, regardless of the age group, while Reinke edema was more frequently observed in women. A directly proportional relation between the frequency of laryngeal cancer and age increase was also observed. No significant differences were observed in professional voice users. Conclusion Further researches are required to properly comprehend the factors associ- ated with laryngeal lesions and determine prevention and treatment approaches.

Manejo anestésico de resección de quiste de vallécula en neonato. A propósito de un caso / Anesthetic management of vallecular cyst resection in neonate. A case report

Difficult airway management is one of the most important challenges an anesthesiologist faces. It is due to the high morbidity and mortality that it entails. The challenge is even greater if the patient is a newborn. For this reason, we should have different strategies that allow us to anticipate and treat possible complications derived from the procedure. In this case, we present a newborn with vallecular cyst and respiratory distress who is admitted for cyst resection. The gold-standard in anticipated difficult airway management is the fibrobronchoscope. We decided to perform an alternative management by means of orotracheal intubation with videolaryngoscope (Glydescope®) in spontaneous ventilation

El manejo de una vía aérea difícil es uno de los retos más importantes a los que puede enfrentarse un anestesiólogo debido a la elevada morbimortalidad que conlleva. El reto aún es mayor si el paciente es un neonato. Por este motivo, debemos contar con diferentes estrategias que permitan anticipar y poder tratar las posibles complicaciones derivadas del procedimiento. En este caso, presentamos un neonato con quiste de vallécula con clínica de trabajo respiratorio que es admitido para cirugía de exéresis del quiste. El gold standard en el manejo de una vía aérea difícil conocida es el fibrobroncoscopio. Nosotros decidimos realizar un manejo anestésico alternativo mediante intubación orotraqueal con videolaringoscopio (Glydescope®) en ventilación espontánea.

Comparison of the efficacy of vocal training and vocal microsurgery in patients with early vocal fold polyp / Comparação entre a eficácia do treinamento vocal e da fonocirurgia em pacientes com pólipo de prega vocal incipiente

Abstract Introduction: Vocal fold polyp is a benign proliferative disease in the superficial lamina propria of the vocal fold, and vocal microsurgery can improve the voice quality of patients with vocal fold polyp. In preliminary studies, we found that vocal training could improve the vocal quality of patients with early vocal fold polyp. Objective: This study aimed to compare the efficacies of vocal training and vocal microsurgery in patients with early vocal fold polyp. Methods: A total of 38 patients with early vocal fold polyp underwent 3 months of vocal training (VT group); another 31 patients with early vocal fold polyp underwent vocal microsurgery (VM group). All subjects were assessed using laryngostroboscopy, voice handicap index, and dysphonia severity index, and the efficacies of vocal training and vocal microsurgery were compared. Results: The cure rates of vocal training and vocal microsurgery were 31.6% (12/38) and 100% (31/31), respectively. The intragroup paired-sample t-test showed that the post treatment vocal handicap index, maximum phonation time, highest frequency (F0-high), lowest intensity (I-low), and dysphonia severity index in both the VT and VM groups were better than those before treatment, except for the jitter value. The intergroup independent-sample t-test revealed that the emotional values of vocal handicap index (t = − 2.22, p = 0.03), maximum phonation time (t = 2.54, p = 0.013), jitter (t = − 2.11, p = 0.03), and dysphonia severity index (t = 3.24, p = 0.002) in the VT group were better than those in the VM group. Conclusions: Both, vocal training and vocal microsurgery could improve the voice quality of patients with early vocal fold polyp, and these methods present different advantages.

Resumo Introdução: O pólipo de prega vocal é uma doença proliferativa benigna da camada superficial da lâmina própria da prega vocal e a microfonocirurgia pode melhorar a qualidade vocal desses pacientes. Em estudos preliminares, observamos que o treinamento vocal era capaz de melhorar a qualidade vocal de pacientes com pólipo incipiente de prega vocal. Objetivo: Este estudo teve como objetivo comparar a eficiência entre treinamento vocal e microfonocirurgia em pacientes com pólipo incipiente de prega vocal. Método: Um total de 38 pacientes com pólipo incipiente de prega vocal foram submetidos a três meses de treinamento vocal (grupo TV); outros 31 pacientes foram submetidos à microfonocirurgia (grupo MC). Todos os indivíduos foram avaliados por meio de laringoestroboscopia, índice de desvantagem vocal e índice de severidade da disfonia e a eficácia entre treinamento vocal e microfonocirurgia foi comparada. Resultados: As taxas de cura do treinamento vocal e da microfonocirurgia foram de 31,6% (12/38) e 100% (31/31), respectivamente. O teste t para amostras pareadas intragrupo mostrou que o índice de desvantagem vocal pós-tratamento, tempo máximo de fonação, frequência máxima, intensidade mínima e índice de severidade da disfonia nos grupos TV e MC foram melhores do que aqueles antes do tratamento, exceto pelo valor do jitter. O teste t para amostras independentes intergrupos revelou que o valor emocional do índice de desvantagem vocal (t = -2,22, p = 0,03), tempo máximo de fonação (t = 2,54, p = 0,013), jitter (t = -2,11, p = 0,03) e índice de severidade da disfonia (t = 3,24, p = 0,002) no grupo TV foram melhores do que os do grupo MC. Conclusões: Tanto o treinamento vocal quanto a microfonocirurgia podem melhorar a qualidade da voz de pacientes com pólipo incipiente de prega vocal e esses métodos apresentam diferentes vantagens.

A morphological classification for vocal fold leukoplakia / Classificação morfológica das leucoplasias de prega vocal

Abstract Introduction: There is still no general method for discriminating between benign and malignant leukoplakia and identifying vocal fold leukoplakia. Objective: To evaluate the reliability of a morphological classification and the correlation between morphological types and pathological grades of vocal fold leukoplakia. Methods: A total of 375 patients with vocal fold leukoplakia between 2009 and 2015 were retrospectively reviewed. Two observers divided the vocal fold leukoplakia into flat and smooth, elevated and smooth, and rough type on the basis of morphological appearance. The inter-observer reliability was evaluated and the results of classification from both observers were compared with final pathological grades. Clinical characteristics between low risk and high risk group were also analyzed. Results: The percentage inter-observer agreement of the morphological classification was 78.7% (κ = 0.615, p < 0.001). In the results from both observers, the morphological types were significantly correlated with the pathological grades (p1 < 0.001, p2 < 0.001, Kruskal-Wallis test; r1 = 0.646, p1 < 0.001, r2 = 0.539, p2 < 0.001, Spearman Correlation Analysis). Multivariate analysis showed patient's age (p = 0.018), the size of lesion (p < 0.001), and morphological type (p < 0.001) were significantly different between low risk group and high risk group. Combined receiver operating characteristic curve analysis of significant parameters revealed an area under the receiver operating characteristic curve of 0.863 (95% CI 0.823-0.903, p < 0.001). Conclusions: The proposed morphological classification of vocal fold leukoplakia was consistent between observers and morphological types correlated with pathological grades. Patient's age, the size of lesion, and morphological type might enable risk stratification and provide treatment guidelines for vocal fold leukoplakia.

Resumo Introdução: Ainda não há um método universal estabelecido para diferenciar entre a leucoplasia benigna e maligna ou identificar as leucoplasias das pregas vocais. Objetivo: Avaliar a confiabilidade de uma classificação morfológica e a correlação entre os tipos morfológicos e os graus histopatológicos das leucoplasias de pregas vocais. Método: Os registros de 375 pacientes com leucoplasia da prega vocal assistidos entre 2009 e 2015 foram revisados retrospectivamente. Dois observadores dividiram a leucoplasia da prega vocal entre tipo plano e liso, elevado e liso, e rugoso, com base na aparência morfológica. A confiabilidade interobservador foi avaliada e os resultados de classificação de ambos os observadores foram comparados com os graus histopatológicos finais. As características clínicas entre os grupos de baixo risco e alto risco também foram analisadas. Resultados: A porcentagem da concordância interobservador da classificação morfológica foi de 78,7% (κ = 0,615, p < 0,001). Nos resultados de ambos os observadores, os tipos morfológicos correlacionaram-se significativamente com os graus histopatológicos (p1 < 0,001, p2 < 0,001, teste de Kruskal-Wallis; r1 = 0,646, p1 < 0,001, r2 = 0,539, p2 < 0,001, análise de correlação de Spearman). A análise multivariada mostrou que a idade do paciente (p = 0,018), o tamanho da lesão (p < 0,001) e o tipo morfológico (p < 0,001) foram significativamente diferentes entre o grupo de baixo risco e o de alto risco. A análise da curva ROC (Receiver Operating Characteristic) combinada de parâmetros significativos revelou uma área sob a curva de 0,863 (IC 95%: 0,823 ± 0,903, p < 0,001). Conclusões: A classificação morfológica proposta para leucoplasia de prega vocal foi consistente entre observadores e os tipos morfológicos correlacionaram-se com os graus histopatológicos. A idade do paciente, o tamanho da lesão e o tipo morfológico podem permitir a estratificação de risco e fornecem diretrizes de tratamento para a leucoplasia da prega vocal.

Variant of the Technique for Laryngeal Microsurgery in Cases of Difficult Laryngoscopy

Abstract Introduction Low exposure of the larynx can make laryngeal microsurgery difficult or even impossible. The application of rigid and contact endoscopy enabled oblique and retrograde angled visualization, allowing transoperative staging with greater reach of the anatomical areas. However, there is difficulty or even impossibility of performing the surgical act, due to the incompatibility of the angled path with the straight surgical tools. Objective To demonstrate the efficiency of the variant of the technique for laryngeal microsurgery in cases of difficult laryngoscopy and to analyze the new surgical instruments specific to the endoscopic procedure. Methods This is a cross-sectional retrospective study, based on the analysis of 30 medical records of patients treated surgically at a philanthropic hospital in the state of Sergipe, Brazil, between the years of 2014 and 2015. Results The technical variant used 30- and 70-degree endoscopes that provided complete oblique view of the endolarynx. The association of angled instruments (forceps, suction pumps, retractors and scissors) enabled the execution of the surgical procedures. Conclusion The association of rigid endoscopy with angled instruments promoted full visualization of the surgical lesion and operative resolution. (AU)

Enfermedad de Rosai-Dorfman con compromiso laríngeo: a propósito de un caso / Rosai-Dorfman disease with laryngeal involvement: about a case

RESUMEN La enfermedad de Rosai-Dorfman (ERD) o histiocitosis sinusal con linfadenopatía masiva es una enfermedad infrecuente, de etiología desconocida caracterizada por linfadenopatías cervicales masivas bilaterales. El compromiso extraganglionar puede ocurrir en diferentes sitios, incluida la vía aérea, en la cual la localización nasosinusal es la más frecuente, pero puede comprometer también otros sitios de la vía aérea superior. Dentro de éstos, el compromiso laríngeo es muy poco frecuente. Se presenta el caso de una paciente de 82 años con antecedentes de ERD localizada en los ganglios linfáticos cervicales en remisión espontánea, que desarrolló posteriormente una obstrucción subaguda de las vías respiratorias. La tomografía computarizada y la nasofaringolaringoscopía mostraron lesiones subglóticas que obstruían severamente las vías respiratorias. Se realizó una traqueostomía de emergencia y biopsia de las lesiones, confirmando el diagnóstico de ERD extranodal.

ABSTRACT Rosai-Dorfman disease or sinus histiocytosis with massive lymphadenopathy is a rare disease of unknown etiology characterized by bilateral massive cervical lymphadenopathy. Extranodal involvement can occur in different sites including airway where nasosinusal involvement is common but this disease may occur in other sites of the upper airway. Laryngeal involvement is rare. We present the case of an 82-year-old female patient with a history of Rosai-Dorfman disease located in cervical lymph nodes in spontaneous remission that subsequently develops airway obstruction. Computed tomographic scan and nasopharyngolaryngoscopy showed subglottic lessons that severely obstructed the airway. Emergency tracheotomy and biopsy were performed, confirming the diagnosis of extranodal RDD. Patient was observed and tracheostomy was maintained with good tolerance.

Amiloidosis laríngea: a propósito de un caso / Laryngeal amyloidosis: a case report

RESUMEN La amiloidosis es una enfermedad poco frecuente, de etiología desconocida, caracterizada por la presencia de depósitos extracelulares de proteínas fibrilares en diversos órganos y tejidos, teniendo una amplia gama de manifestaciones clínicas según localización y tamaño de los depósitos. En cabeza y cuello, el sitio de presentación más frecuente es la laringe. Suele presentarse con disfonía y/o disnea progresiva, cuyo tratamiento definitivo, sin estar estandarizado, suele ser la resección quirúrgica. Se presenta a continuación el caso de un paciente de 78 años, con historia de disnea en reposo y estridor laríngeo leve de 6 meses de evolución, cuya nasofibroscopía evidenció una masa subglótica, determinando lumen crítico de vía aérea superior. Biopsia reveló amiloidosis, siendo tratado de manera exitosa con exéresis tumoral vía laringoscopía directa.

ABSTRACT Amyloidosis is a rare disease of unknown etiology, characterized by the presence of extracellular acumulations of fibrillar proteins in a variety of organs and tissues, with a wide range of clinical manifestations depending on the location and size of the deposits. In head and neck, the most common site of presentation is the larynx. It usually presents with dysphonia and / or progressive dyspnea, whose definitive treatment, without being standardized, is usually surgical resection. A case of a 78-year-old patient with a history of dyspnea at rest and mild laryngeal stridor of 6 months of evolution is presented, whose nasofibroscopy showed a subglottic mass at the cricoid level, determining a critical upper airway lumen. Biopsy revealed extensive amyloidosis of the upper respiratory tract mucosa, being successfully treated with tumoral excision under direct laryngoscopy.

El 75% de los pacientes operados presentó mejoría en patrón de onda mucosa videolaringoestroboscópica. Todos los pacientes en los que se disponía de encuestas de valoración subjetiva de la voz pre y posoperatorias demostraron mejoría vocal significativa. Conclusión: Los quistes de cuerda vocal son lesiones que afectan a niños y adultos. La videolaringoestroboscopía es clave en el diagnóstico de estas lesiones, y el tratamiento quirúrgico con microfonocirugía es efectiva en cuanto a resultados vocales desde el punto de vista anatómico y funcional.

Introduction: Vocal cord cysts are a relatively frequent cause of dysphonia. Their origin is still controversial, and their diagnosis and management continue to be a clinical challenge. Aim: To describe and analyze the clinical characteristics of vocal cord cysts in our series of patients. Material and method: Descriptive retrospective study of patients with diagnosis of vocal cord cyst attended in our center between June 2012 and December 2015. Results: 44 patients had the diagnosis of vocal cord cyst, which represents 4.32% of the patients that attended our Voice Center during that period. Most of the patients were adults, and among them 68.29% corresponded to women. 34.1% of the patients were submitted to surgical treatment with microphonosurgery technique. 75% of the surgical patients presented an improvement in the pattern of the videolaryngostroboscopic mucosal wave. All the patients in which pre and postsurgical subjective voice assessment polls were available, showed a significant voice improvement. Conclusion: Vocal cord cysts are lesions that affect both children and adults. The videolaryngostroboscopy evaluation is key in the diagnosis of these lesions, and the surgical treatment with microphonosurgery is effective in terms of anatomical and functional vocal results.

Pólipo bilateral de cuerda vocal: presentación de un caso clínico / Bilateral vocal cord polyp: case report

Los pólipos de cuerda vocal son lesiones laríngeas benignas. Se asocian a micro-traumatismos por mal uso vocal que generan remodelación de la lámina propia y el epitelio. Es más frecuente en hombres entre los veinte y cuarenta años. En la gran mayoría de los casos se presenta de manera unilateral. Si bien estas lesiones están bien documentadas en la literatura, es raro encontrar presentaciones bilaterales, por lo que su enfrentamiento y manejo puede ser discutible. Se presenta el caso de una paciente de sexo femenino de 41 años, fumadora, que consulta por disfonía de larga data. Se diagnostican pólipos bilaterales de cuerda vocal, realizando una intervención quirúrgica en un tiempo, con un resultado favorable.

Vocal cord polyps are benign Iaryngeal lesions. They are associated to micro traumatisms because ofvocal misuse, generating a remodelation of the lamina propria and the epithelium. It is more common in men between twenty and forty years of age. In the vast majority of cases it unilaterally occurs. While these are well documented injuries in the literature, it is rare to find bilateral presentations, so their confrontation and management may be debatable. We present the case of a female patient, smoker, who consulted for chronic dysphonia. Bilateral vocal cord polyps were diagnosed, performing a bilateral resection with a positive outcome.

Abordaje cerrado en patología de vía aérea superior con el uso de microelectrodos: nuestra experiencia / Approach closed upper airway pathology using microelectrodes: our experience

El láser como alternativa a la cirugía abierta de la vía aérea superior ha venido a modificar la forma de abordaje de las patologías en esta área, pero no deja de ser un procedimiento costoso que no está al alcance de todos los servicios. Por este motivo se han reinventado nuevas formas de abordaje que cumplan los mismos requisitos tanto de la cirugía abierta como con láser pero con un menor coste. Presentamos una serie de 30 casos realizados en un período de 6 años por motivos tanto tumorales como no, en los que se realizaron abordajes cerrados a través de microcirugía con disección mediante microelectrodos. Obteniendo pocas complicaciones y una disminución de la estancia hospitalaria significativa. Con lo cual nos parece una técnica eficiente para abordajes de este tipo.

The laser as an alternative to open surgery of the upper airway has come to change the form of approaching the disease in this area, but it is still an expensive procedure that is not available to all services. For this reason a new ways of approach to meet the same requirements both open as laser but at a lower cost surgery. We present a series of 30 cases performed over a period of 6 years for reasons as much tumor, which closed approaches through microsurgical dissection were performed using microelectrodes. Obtaining few complications and significant decreased hospital stay. Our considerations is it seems an efficient technique for such approaches.

Quiste de vallécula como causa de estridor congénito: reporte de un caso y revisión de la literatura / Vallecula cyst as a cause of congenital stridor: case report and literature review

El quiste de vallécula congénito es una malformación de vía aérea poco frecuente que se manifiesta principalmente con estridor laríngeo y que puede plantear problemas diagnósticos y terapéuticos complejos, a menudo en situaciones de riesgo vital. Se presenta el caso de un recién nacido de pretérmino (RNPT) de 36 semanas pequeño edad gesta-cional (PEG), portador de un estridor laríngeo congénito y mal incremento pondoestatural que en relación a una infección respiratoria baja, presentó empeoramiento del estridor laríngeo a los 48 días de edad cronológica. Por insuficiencia respiratoria aguda requirió de intubación orotraqueal que no resultó dificultosa. La extubación fue fallida por presentar estridor inspiratorio franco. La nasofibroscopía demostró una lesión de aspecto quístico en base de lengua que desplazaba la epiglotis hacia posterior obstruyendo parcialmente el lumen de la vía aérea. Por laringoscopía directa se realizó marsupialización. Se realiza la revisión bibliográfica y se analiza el caso y su tratamiento.

Congenital vallecular cyst is a rare airway malformation mainly manifested by laryngeal stridor and could generate complex diagnostic and therapeutic problems, often in life-threatening situations. We present the case of a pre-term newborn of 36 weeks small for gestational age, who at 48 days of chronological age showed worsening of a congenital laryngeal stridor in the context of a lower respiratory tract infection associated to low weight gain from birth. For reasons of acute respiratory failure, orotracheal intubation was executed which was not difficult. Extubation was failed because the child presents significant inspiratory stridor. Nasofibroscopy showed a cystic lesion of the tongue base that pushed backward the epiglottis obstructing partially the airway lumen. Marsupialization was performed by direct laryngoscopy. A Bibliographic review was done and the case and its treatment are discuss.

Las lesiones adquiridas que con mayor frecuencia debemos diagnosticar y tratar son las lesiones post intubación, principalmente la estenosis subglótica. En este capítulo se describen estas afecciones de la vía aérea del niño, haciendo énfasis en la importancia de un diagnóstico precoz y preciso además de definir las alternativas modernas de tratamiento.

The descriptive review, from recurrent respiratory papillomatosis of the disease, an enigmatic / A revisão descritiva da papilomatose respiratória recorrente da doença, um enigmático

INTRODUCTION: The recurrent respiratory papillomatosis (RRP), which is caused by the human papilomavirus type 6 and 11, is the most common benign neoplasm in the larynx among infants and the second more frequent cause of the hoarseness in childhood. Is a enigmatic disease that can be devastating for those whom are affected. Is way misunderstood, and the investigation is still on matter. OBJECTIVE: This review had as objective provide a global vision and an update of what is recognized about the RRP and that is ahead of interns therapies. This surgical and adjuvant was performed through the research of database PubMed, MEDLINE, Cumulative index to nursing and health, Allied Literature and Cochrane. Eletronic library sought to use the headers of the subject "Recurrent Respiratory Papillomatosis", "Juvenile Laryngeal Papillomatosis", "Respiratory Papillomatosis", "Pediatric Laryngeal Obstruction" and "Airway Management". The obtained results were analyzed of relevance for the theme. DISCUSSION: The human papillomavirus (HPV) is a little DNA virus that contain. The recurrent respiratory papillomatosis can affect people of any age, with the younger patient identified in a day of age and the oldest with 84 years. The most common presentation is the supporter of the RRP, it is the hoarseness. The therapy has been repetitive and debulking. The objective is to erradicate the disease, without damaging the normal structures. None modality has proven effective in the eradication of RRP. CONCLUSION: Recurrent Respiratory Papillomatosis is a frustrating disease, capricious with the potential of the morbid consequences by the cause of involvement of the airway and the risks of malignant degeneration.

INTRODUÇÃO: A papilomatose respiratória recorrente (PRR), que é causado pelo papilomavírus humano tipos 6 e 11, é a neoplasia benigna mais comum da laringe entre as crianças ea segunda causa mais frequente de rouquidão na infância. É uma doença enigmática que pode ser devastadora para aqueles a quem ela afeta. É muito mal compreendido, e investigação continua na ativa assunto. OBJETIVO: Esta revisão teve por objectivo proporcionar uma visão global e uma atualização do que é conhecido sobre RRP e que está à frente de interms therapies.This cirúrgica e adjuvante foi realizada através de pesquisa das bases de dados PubMed, MEDLINE, Index cumulativa de Enfermagem e Saúde Allied Literatura e Cochrane biblioteca electrónica procurou usar os cabeçalhos de assunto ''papilomatose respiratória recorrente'', ''papilomatose laríngea juvenil'', ''papilomatose respiratória'', ''obstrução laríngea pediátrica'' e ''gestão das vias aéreas''.

A papilomatose respiratória recorrente pode afetar pessoas de qualquer idade, com o paciente mais jovem identificado em um dia de idade eo mais velho de 84 anos. A apresentação mais comum é o sustentáculo da PRR é hoarseness. The de terapia tem sido repetida debulking. O objetivo é erradicar a doença, sem danificar as estruturas normais. Nenhum única modalidade tem mostrado ser eficaz na erradicação da PRR. CONCLUSÃO: Papilomatose respiratória recorrente é uma doença frustrante caprichoso com o potencial para consequências mórbidas por causa de seu envolvimento das vias aéreas eo risco de degeneração maligna.

Laringocele como diagnóstico diferencial de quiste tiroideo / Laryngocele as a differential diagnosis of a thyroid cyst

A cervical mass is a usual complaint within the clinical practice. Among possible causes, thyroid cysts and nodules are frequent findings. However, there are differential diagnoses that arise from neighboring structures, which can be difficult to assess. We report an 18 years old male presenting with a cervical mass, clinically and ecographically suggestive of a right thyroid cyst. Fine needle aspiration was negative for neoplastic cells. Within surgery a paratracheal lesion was identified and resected. The histological findings were compatible with a laryngocele. A laryngocele is an abnormal dilatation of the laryngeal sacule that can simulate a thyroid cyst. Computarized tomography and magnetic resonance are of great importance in its diagnosis, but sometimes is found within surgery or in the anatomopathologic study.

Las masas cervicales son un motivo de consulta usual dentro de la práctica clínica. Dentro de estas, los nódulos y quistes de origen tiroideo son hallazgos frecuentes. Aún así, existen diagnósticos diferenciales originados de estructuras vecinas a la glándula tiroides, cuyo diagnóstico inicial es difícil. Presentamos el caso de un varón de 18 años con una masa cervical derecha, clínica y ecográficamente sugerente de un quiste tiroideo. La punción-aspiración con aguja fina fue negativa para células neoplásicas. En el intraoperatorio se identificó una lesión paratraqueal derecha que fue resecada. El diagnóstico histológico fue compatible con un laringocele. El laringocele es una dilatación anormal del sáculo laríngeo que puede simular un quiste tiroideo. La tomografía computarizada y la resonancia magnética son de gran utilidad en su diagnóstico, pero en ocasiones éste se realiza en el intraoperatorio o mediante el estudio anatomopatológico.

Amiloidose laríngea nodular isolada: relato de caso / Isolated laryngeal amyloidosis nodular: a case report

Introdução: A amiloidose isolada da laringe é rara, sendo a localização isolada mais comum em cabeça e pescoço. Pode ser dividida em difusa e nodular, sendo o tratamento prioritariamente cirúrgico. Objetivo: Descrever um caso de amiloidose nodular isolada de laringe, com revisão da literatura. Relato do Caso: Paciente do sexo feminino, 23 anos, apresentou-se com queixas de bolo cervical e disfonia há cerca de 3 meses. A videolaringoscopia revelou lesão de aspecto polipoide de grande volume em prega vocal esquerda. Submetida à remoção por microcirurgia de laringe, o laudo histopatológico foi compatível com amiloidose, sendo submetida à investigação clínica adicional simplificada para localizações extralaríngeas de amiloidose, a qual foi negativa. Permanece em acompanhamento clínico e laringoscópico semestral. Comentários Finais: A amiloidose isolada da laringe, apesar de rara, deve ser sempre cogitada pelo otorrinolaringologista, uma vez que se trata da apresentação clínica mais frequente da doença em cabeça e pescoço, com aspecto muitas vezes indistinguível ao de outras lesões benignas. É indispensável a investigação para manifestações extralaríngeas.

Introduction: Isolated amyloidosis of the larynx is rare, being the single most common location in head and neck. Can be divided into diffuse and nodular, and the surgical treatment priority. Objective: To describe a case of isolated nodular amyloidosis of the larynx, with review of literature. Case report: A female patient, 23 years, presented with complaints of dysphonia and cervical cake for about three months. A laryngoscopy revealed a polypoid lesion of large volume in the left vocal cord. Underwent microsurgery for the removal of the larynx, the histopathological report was consistent with amyloidosis, and underwent further simplified for clinical research locations extralaryngeal of amyloidosis, which was negative. It remains in clinical and laryngoscopic semester. Final Comments: The isolated amyloidosis of the larynx, although rare, should always be entertained by the otolaryngologist, since it is the most frequent clinical presentation of disease in head and neck, often indistinguishable in appearance to that of other benign lesions. It is indispensable for research extralaryngeal demonstrations.
