Reconstrução de palato com malha de polipropileno e prótese acrílica para correção de fístula oronasal adquirida em cão / Palate reconstruction with polypropylene mesh and acrylic prosthesis in dog for correcton of acquired oronosal fistulae

As fístulas oronosais adquiridas são defeitos que permitem a comunicação anormal entre as cavidades oral e nasal. Inúmeras causas podem ser atribuídas à etiologia de tal defeito. O presente trabalho visa relatar o caso de um cão com fístula oronasal adquirida que foi submetido à reconstrução cirúrgica do palato com o uso de malha de polipropileno e prótese acrílica. Após estabilização do quadro clínico e remoção manual das larvas, o paciente foi encaminhado para o desbridamento cirúrgico das lesões orais e correção do defeito no palato. A palatoplastia foi realizada com o uso da malha e resina de polimetilmetacrilato autopolimerizável. A malha foi suturada sobre o defeito palatino com pontos simples separados e fio náilon 3-0 nas extremidades da ferida. Em seguida, a resina foi preparada e, ao atingir consistência adequada, foi aplicada e modelada sobre o a malha de polipropileno com o auxílio de um descolador de Molt, sendo também suturada nas bordas da fístula com pontos simples separados e fio náilon 3-0. No mesmo tempo cirúrgico foi inserida uma sonda esofágica para alimentação enteral. Devido complicações cirúrgicas no pós operatório, o paciente foi submetido a mais duas intervenções cirúrgicas para desfecho satisfatório do tratamento. Conclui-se que associação entre a tela de polipropileno e a prótese acrílica foi uma alternativa exequível para a palatoplastia em cão.

Acquired oronosal fistulae are abnormal communication between the oral and nasal cavities. A oronasal fistula can be the result of different causes, like oral myiasis. The objetctive of these paper is to report the case of a dog with acquired oronasal fistula that underwent surgical reconstruction of the palate using polypropylene mesh and acrylic prosthesis. After stabilization of the patient ́s clinical condition and mecanic removal of the larvae, the dog was referred for surgical debridement of the oral lesions and correction of the defect in the palate. Palatoplasty was performed using a mesh and polymethylmethacrylate resin. The mesh was sutured over the palatal defect with separate simple suture and 3-0 naylon thread at the ends of the wound. Then, the resin was prepared and, upon reaching adequate consistency, it was applied and shaped over the polypropylene mesh with Molt peeler. It was also sutured on the edges of the fistula with separate simple suture and 3-0 nylon suture. At the same surgical time, an esophageal tube was inserted for enteral feeding. Due to complications, the dog underwent two more surgical interventions for a satisfactory treatment outcome. It is concluded that the association between the polypropylene mesh and the acrylic prosthesis was a practical alternative for palatoplasty in dogs after oral myiasis.

The use of presurgical orthopedics (OR: 0,014; p<0,000) and feeding with breast milk (OR: 0,033; p<0,003) were protective factors. DISCUSSION. Presurgical orthopedics was the best molding option in patients with wide clefts for the approximation of the cleft bone segments, as a significant protective factor, exclusive breastfeeding was found, data that coincides with the study by López YD., where he mentioned that it produced greater stimulation for palatine ridge fusion although it was not statistically significant. CONCLUSION. Statistically significant factors associated with the development of palatal fistula were the use of pre-surgical orthopedics and feeding with breast milk, classified as protective.

Manejo cirúrgico de sequestro ósseo pósexodontia em paciente portador de displasia cemento-óssea florida: relato de caso / Surgical management of post-exodontia bone sequestral in patients with displasia bone cement-florida: case report

A displasia cemento-óssea florida (DCOF) é uma condição não neoplásica, esclerosante limitada aos ossos maxilares, relacionada ao osso do processo alveolar e, na maioria dos casos envolvendo bilateralmente a mandíbula. É uma condição rara que se apresenta nos maxilares, de forma autolimitante, evoluindo de um estágio osteolítico para osteoblástico, com prevalência pelo gênero feminino, de meia idade a idosas, melanoderma. Dessa forma, o objetivo do trabalho é relatar o caso clínico de uma paciente portadora de displasia cemento-óssea florida apresentando osteomielite local após exodontia.Paciente de 57 anos de idade, melanoderma, compareceu ao ambulatório do Hospital Manoel Victorino (Salvador, BA) do serviço de Cirurgia e Traumatologia Bucomaxilofacial, referindo histórico de exodontia do dente 47 há aproximadamente 02 anos, sem cicatrização local e presença de supuração e odor fétido. Ao exame intrabucal notou- se a presença fístula na região do dente 47 com secreção purulenta espontânea e presença de tecido necrótico. Ao exame de imagem (radiografia panorâmica), foi observado presença de lesões radiopacas multifocais das áreas posteriores mandibulares. Foi submetida a cirurgia, sob anestesia geral, para curetagem de sequestro ósseo e fechamento primário do defeito por primeira intenção e acompanhamento. O objetivo do trabalho foi relatar um caso clínico de um sequestro ósseo mandibular em uma paciente com displasia cemento- óssea florida(AU)

Flowery cementum-bone dysplasia (DCOF) is a non-neoplastic, sclerosing condition limited to maxillary bones, related to the alveolar process bone and, in most cases, bilaterally involving the mandible. When infected can lead to suppuration and kidnapping, resulting in a picture of osteomyelitis. It is a rare condition that occurs in the jaws, in a selflimiting way, evolving from an osteolytic stage to osteoblastic, with prevalence by the female gender, from middle age to the elderly, melanoderma. Therefore, the aim of this paper is to report a diagnosed case of florid cemento-ousseous dysplasia, presenting local osteomyelitis after a extraction. Patient 57 years old, melanoderma, attended the outpatient clinic of the Hospital Manoel Victorino (Salvador, BA) of the Bucomaxillofacial surgery and traumatology department, referring to a history of the right mandible exodontia for approximately 2 years, without local scarring and presence of odor and suppuration fetid The intraoral examination revealed the presence of a fistula in the region distal to the tooth 47 with spontaneous purulent secretion and necrotic tissue. At the imaging examination (panoramic radiography), the presence of multifocal radiopaque lesions of the mandibular posterior areas was observed. She underwent surgery under general anesthesia for curettage of bone sequestration and primary closure of the defect by first intention and follow-up. The objective of this study was to report a clinical case of a mandibular bone sequestration in a patient with florid cementoosseous dysplasia(AU)

Fechamento de comunicação buco-sinusal utilizando o corpo adiposo bucal: Relato de Caso Clínico / Closure of oroantral communications using buccal fat pad: technique report

Introdução: As comunicações buco-sinusais (CBS) são complicações cirúrgicas relativamente frequentes na prática odontológica, relacionadas à extração dos molares superiores. As CBS permitem a passagem de alimentos e outras substâncias para o interior do seio maxilar, propiciando, assim, quadros infecciosos conhecidos como Sinusites. O tratamento das CBS é desafiador. Objetivo: Relatar um caso clínico de fístula bucossinusal tratada pela técnica de fechamento com o corpo adiposo bucal. Relato de caso: paciente do gênero masculino, 59 anos, leucoderma, sem alterações de ordem sistêmica, compareceu ao ambulatório de Pós-graduação da Universidade do Sagrado Coração relatando como queixa principal o fato de "sair líquidos pelo nariz" durante alimentação e havia iniciado após realizar exodontia de raiz residual do dente 16. O mesmo relatou que após a exodontia foi realizada uma tentativa de fechamento da fístula buco-sinusal através do reposicionamento do retalho vestibular e não foi obtido sucesso. Após 45 dias de condicionamento da mucosa do seio maxilar através de irrigações com soro fisiológico e clorexidina a 0,12% foi proposto ao paciente e realizado o fechamento da fístula buco-sinusal através da utilização do corpo adiposo bucal. Conclusão: atualmente para se alcançar o alto índice de sucesso no fechamento de comunicações busco-sinusais utilizamos esta técnica descrita, por ser um procedimento simples e que porprociona resultados satisfatórios ao paciente.

Introduction: Bucosinusal communications are relatively frequent surgical complications in dental practice. Although several conditions are related to this type of communication, the exodontia of upper posterior teeth presents as the main etiological factor. They are diagnosed through fistulas, which communicate the buccal and sinus cavities, thus allowing the passage of food and other substances into the maxillary sinus, thus providing infectious pictures known as Sinusites. Objective: through the report of a clinical case of buccosalusal fistula, we will focus on the success of the closure of buccomasinal communication with Bichat Adipose Body. Technique report: male patient, 59 years old, leucoderma, with no systemic alterations, who attended the University of the Sacred Heart Postgraduation outpatient clinic reporting as a main complaint the fact of "getting fluids through the nose" during feeding and that this had started after performing a residual root exodon of element 16. It also reported that after the exodontia, an attempt was made to close the buccosinusal fistula through the repositioning of the vestibular flap and no success was achieved. After 45 days of conditioning the maxillary sinus mucosa through irrigations with saline solution and 0.12% chlorhexidine, the patient was proposed and the buccosinusal fistula was closed using the Bichat Adipose Body. Conclusion: Today, in order to achieve the high success rate in the closure of buscossinusal communications, we use the Bichat Adipose Body, because it is a simple procedure and provides satisfactory results for the patient.

Pólipos bucales como complicación de una fractura de la tuberosidad / Oral polyps as a complication of a tuberosity fracture

Introducción: la importancia de los senos maxilares se vuelve más clara cuando se entiende que los dientes son responsables del 10 al 12 por ciento de las sinusitis maxilares. Objetivo: caracterizar un caso de pólipos bucales como complicación de una fractura de la tuberosidad. Presentación del caso: se valora una paciente femenina de 62 años que refiere tener una bolita en la boca desde hace 3 semanas, que le ha ido en aumento. Al examen físico bucal encontramos un aumento de volumen en la región posterior maxilar izquierda. Al profundizar en el interrogatorio la paciente refiere que le realizaron una extracción de un molar en el área del aumento de volumen 6 meses atrás, que salió con un fragmento de hueso y que sentía que se le salía el aire, por lo que le suturaron en ese momento. Indicamos medios auxiliares de diagnóstico. Se llegó al diagnóstico de que se trataba el aumento de volumen de pólipos sinusales en una fístula bucoantral como complicación de una fractura de la tuberosidad antigua. Se decidió realizar tratamiento mediante la indicación de antimicrobiano, gotas nasales, inhalaciones, y la realización una técnica de Caldwell Luc, con eliminación de los pólipos presentes, más fistulectomía y cierre mediante colgajo vestibular deslizante. Se tomó muestra para biopsia que informó la presencia de una sinusitis crónica polipoide. Conclusiones: la cirugía bucal es de imprescindible conocimiento para todos los profesionales de la rama estomatológica. El caso presentado de pólipos bucales en una fístula bucoantral como complicación de una fractura de la tuberosidad, de infrecuente presentación en la clínica, contribuye a resaltar la importancia de realizar un correcto interrogatorio para determinar las herramientas diagnósticas y terapéuticas a emplear(AU)

Introduction: the importance of the maxillary sinuses becomes clearer when it is understood that the teeth are responsible for 10 to 12 percent of the cases of maxillary sinusitis. Objective: present a case of oral polyps as a complication of a tuberosity fracture. Case presentation: a 62-year-old female patient attends consultation with a lump in her mouth which she has had for three weeks, during which time it has grown larger. Physical examination reveals a growth in the left posterior maxillary region. During interrogation the patient explained that six months before she was removed a molar from the area of increased volume. The molar had come out with a bone fragment, and she had felt air escaping through the opening, so they sutured right away. We indicated auxiliary diagnostic means. Diagnosis was an increase in the volume of paranasal polyps in an oroantral fistula as a complication of a fracture of the former tuberosity. The treatment indicated was an antimicrobial, nose drops, vaporizations, and performance of a Caldwell Luc technique with removal of the polyps, plus fistulectomy and closure by sliding vestibular flap. A sample was taken for biopsy, which revealed the presence of chronic polypoid sinusitis. Conclusions: training in oral surgery is essential for all dental professionals. The case presented of oral polyps in an oroantral fistula as a complication of a tuberosity fracture, of infrequent clinical presentation, contributes to highlight the importance of proper interrogation to determine the diagnostic and therapeutic tools to be used(AU)

Rehabilitación protésica en pacientes fisurados con fístula buconasal / Prosthetic rehabilitation in patients with cleft lip and buconasal fistula

La fisura labiopalatina consiste en la falta de fusión de los procesos palatinos y labial durante el desarrollo embrionario. Estos pacientes presentan una comunicación buconasal, alteraciones dentarias de forma, tamaño y posición, y un deficiente desarrollo del maxilar. Su tratamiento requiere un trabajo de equipo multidisciplinar, ya que afecta funciones básicas que comprometen su calidad de vida, como comer, hablar o relacionarse socialmente. Aunque la cirugía primaria soluciona mayormente esta anomalía, algunas veces persiste la comunicación entre las cavidades bucal y nasal, lo que se conoce como comunicación o fístula buconasal. Esto supone una mayor dificultad en el cierre quirúrgico, siendo a veces imposible de cerrar a través de la cirugía. En tales casos, la obturación de dicha fístula a través de una prótesis otorga una solución de bajo costo para el paciente y con resultados óptimos a corto y mediano plazo. El objetivo de este artículo es exponer casos de rehabilitación protésica en pacientes con fisura labiopalatina y fístula buconasal posterior al tratamiento quirúrgico.

Cleft lip and palate is the lack of fusion of the palatal and labial processes during embryonic development. Patients are characterised by the presence of buconasal communication, dental alterations, and poor development of the maxilla. Treatment requires multidisciplinary team work, due to the impact on basic functions such as eating, talking or interacting with other people, and even compromising their quality of life. Although primary surgery mostly solves this anomaly, sometimes communication between the oral and nasal cavity persists (called communication or buconasal fistula). This leads to greater difficulty to surgically close it, being impossible in some cases. In these cases, the closure using a prosthesis provides a low-cost solution for the patient, with an optimal result in the short and medium term. The aim of this article is to present cases of prosthetic rehabilitation in patients with cleft lip and buconasal fistula after surgical treatment.

Acquired Palatal Fistula in Patients with Submucous and Incomplete Cleft Palate before Surgery

It is uncommon for a palatal fistula to be detected in individuals who have not undergone surgery, and only sporadic cases have been reported. It is even more difficult to find cases of acquired palatal fistula in patients with submucous or incomplete cleft palate. Herein, we present 2 rare cases of this phenomenon. Case 1 was a patient with submucous cleft palate who acquired a palatal fistula after suffering from oral candidiasis at the age of 5 months. Case 2 was a patient with incomplete cleft palate who spontaneously, without trauma or infection, presented with a palatal fistula at the age of 9 months.

Recurrent Extranodal NK/T-Cell Lymphoma Presenting as a Perforating Palatal Ulcer and Oro-Nasal Fistula

Nasal-type extranodal natural killer/T-cell lymphoma (ENKTL) is a rare disease presenting with non-specific symptoms, typically originating in the nasal cavity, palate, or midfacial region. Oral cavity is an extremely rare site for this type of lymphoma. In this report, we present a case of palatal perforation and oro-nasal fistula as a manifestation of recurrent ENKTL. Complicated disease entity should be considered when surgeons deal with palatal perforation and oro-nasal fistula.

Frequency of oronasal fistulae in complete cleft palate repair

To determine the frequency of oro-nasal fistula in patients undergoing complete cleft palate repair by two flappalatoplasty. Case series. Department of Plastic Surgery, Services Hospital, Lahore, from January to December 2013. Patients admitted to the study place for repair of cleft palate after informed consent obtained were included. Cleft palate was repaired by two-flap palatoplasty, using Bardach technique. Patients were discharged on the second postoperative day and followed-up at third week postoperatively. During follow-up visits, fistulae formation and their sites were recorded on pre-designed proforma. Among the total 90 patients, 40 patients [44.4%] were male and 50 patients [55.6%] were female. The mean age was 6.4 +/- 5.7 years ranging from 9 months to 20 years. At third week follow-up, 5 patients [5.6%] had fistulae formation. Four patients [80%] had anterior fistulae and one patient [20%] had posterior fistula. With two-flap palatoplasty Bardach procedure for repair of cleft palate, the complication of fistula formation was uncommon at 5.6%, provided the repair was tension free and multi-layered

Tratamento endodôntico em molar decíduo com fistula no palato - relato de caso / Endodontic treatment of deciduous molar with palatine fistula - case report

A realização da Endodontia em decíduos com comprometimento pulpar é importante, uma vez que a permanência destes na cavidade bucal servirá de guia para a erupção dos permanentes sucessores. Ocorre que quando a lesão endodôntica não é tratada e se estende além da polpa coronária pode surgir uma fístula, sinal clínico de que na região existe infecção em atividade. A incidência de fístula no palato em crianças é rara. O objetivo deste artigo foi relatar um caso clínico de tratamento endodôntico radical realizado em molar superior decíduo com presença de fístula. Paciente infantil, gênero feminino, 3 anos, apresentava inicialmente edema facial no lado esquerdo e dor de grande intensidade. O dente 64 tinha uma restauração com recidiva de cárie e polpa necrosada com fístula no palato, levando ao diagnóstico de abscesso dentoalveolar agudo. Foi feito como urgência cirurgia de acesso e localização dos condutos radiculares com uso de formocresol como medicação e o dente foi restaurado provisoriamente. Retorno após 7 dias, com sensível melhora do quadro clínico. Com respeito às técnicas de manejo do comportamento infantil, na sequência foi realizado um eficiente preparo biomecânico e obturação com cimento de óxido de zinco e eugenol. A restauração definitiva foi feita com resina composta após 7 dias. Controle após 8 meses não apresentou alterações clínicas ou radiográficas. A manutenção de elementos decíduos na arcada permite completar seu ciclo biológico e proporcionar condições apropriadas para o crescimento e desenvolvimento das bases apicais e do sucessor permanente.

Endodontics in deciduous teeth with compromised pulp is important, since their permanence in the oral cavity will guide the permanent successor eruption. When the endodontic lesion is not treated it extends beyond the coronary pulp and a fistula may appear indicating a clinical sign of infection activity in this site. The incidence of palatal fistula in children is rare. The aim of this paper was to report a clinical case of endodontic treatment performed in a deciduous superior molar presenting fistula. A 3-year-old female patient presented facial edema on the left side and great intensity pain. Dental element 64 was restored. However, it had recurrence of decay and pulpal necrosis with palatal fistula, leading to diagnosis of acute dentoalveolar abscess. As an urgency procedure, access surgery and location of radicular canals were made and formocresol used as an interappointment dressing in pulpectomy with temporary restoration. There was an improvement in her clinical state after 7 days. Respecting the management of infant behavior, it was performed an efficient biomechanical instrumentation and filling with zinc oxide eugenol cement. Definitive restoration was made with composite after 7 days. After 8 months there was no clinical or radiographic worsening. The permanence of deciduous teeth in the dental arches allows the end of their biological cycle and provides appropriate conditions to apical bases growing and development including the permanent successor teeth.

Hard palate fistula and nasal septum perforation after leukemia infection: report of one case / 临床耳鼻咽喉头颈外科杂志

Most of palatal fistula occur from poor repairation of cleft palate, leaving an abnormal channel between mouth and nose. Palatal fistula can cause a series of complications, such as voice and hearing disorder, poor oral and nasal hygiene, psychological diseases and so on. However, hard palate fistula secondary to Leukemia infection is rarely seen, it hasn't been reported yet. We report one case with hard palate fistula and nasal septum perforation after Leukemia infection.

Fístula cutânea odontogênica: relato de caso / Odontogenic cutaneous sinus tract: Case report

Introdução: as fístulas odontogênicas são canais que se originam de um sítio de inflamação dentária e que drenam para as regiões orofacial e do pescoço. Uma das causas mais frequentes para a formação de fístulas odontogênicas é a presença de cáries ou de trauma dentário, com invasão bacteriana do tecido pulpar e posterior necrose pulpar. Objetivo: relatar a história clínica de uma paciente atendida na Faculdade de Odontologia da UESB, apresentando uma fístula cutânea odontogênica. Métodos: paciente de 47 anos de idade, apresentou-se ao serviço de endodontia da UESB queixando-se de uma fístula extrabucal, localizada na região esquerda da face. Depois de consultas a clínicos gerais, otorrinolaringologistas e oftalmologistas, a paciente procurou o atendimento odontológico. Ao exame radiográfico, constatou-se uma lesão cariosa no elemento 22, com presença de patologia periapical. O tratamento endodôntico foi proposto e realizado em única sessão. Resultados: três dias depois, a fístula já havia regredido, restando apenas um cicatriz no local por causa da retração tecidual para o fechamento do orifício de abertura da lesão. Dois meses depois, o exame radiográfico apontou uma formação óssea na região apical do elemento dentário. Conclusão: torna-se evidente a relevância do conhecimento dessa condição por cirurgiões-dentistas e médicos para a correta condução do diagnóstico e do tratamento da patologia

Frequency of fistula formation after two stage repair of cleft palate

To estimate the frequency of fistula formation after two stage repair of cleft palate. A total of 50 patients having completed cleft palate repair with or without lip repair were recruited from December 2007 to February 2009. Patients were diagnosed on history and oral examination. Informed consent was taken from parents. Width of the cleft measured preoperatively. Two stage repairs were done by a single surgeon with a time lapse of six months. Five patients developed clinically significant oronasal fistula. All these fistulas occurred at the junction of hard palate and soft palate within 3 weeks time. The overall rate of true fistula development was 12% over a mean follow up period of 6 months. The incidence of true fistulas that were symptomatic and subsequently required surgical repair was 10%. Fistula rates were higher for more wide clefts but were not affected by gender or age

CONCLUSION: The general rate of oral cutaneous fistulae was 30,3 percent. The significant factors were: T stage, cervical linphadenectomy, pre or postoperative radiotherapy, wound infection and deiscense, and the use of flaps.

Postoperative orocutaneous fistula closure using a vacuum-assisted closure system: a case report

Fleischmann et al. first described the concept of using sub-atmospheric pressure to treat open or infected wounds in 1993. Since then, Argenta and Morykwas developed subatmospheric, or negative pressure dressings in 1997 as a means of managing complicated wounds. Since its introduction in 1997, the vacuum-assisted closure (VAC) system has been used widely in general plastic surgery, general surgery, and orthopedic surgery to manage complicated wounds of the torso and extremities. However, there is a paucity of literature describing its use in the head and neck region, particularly in oral and maxillofacial surgery. We report a successful case of postoperative orocutaneous fistula closure using a VAC system in a 59-year male with a review of the relevant literature.
