ABSTRACT

Abstract Introduction Local anesthesia with sedation has been employed for an increasingly number of otolaryngology procedures, and might be associated with lower surgical morbidity and costs. Facial nerve monitoring is often advisable in otology to minimize the risks of injuries to this cranial nerve, but the principles, techniques and parameters involved have only been studied for procedures under general anesthesia. Objective To report the preliminary outcomes of intraoperative facial nerve moni- toring during otologic procedures under sedation and local anesthesia. Methods A total of five procedures and their respective intraoperative electrophysi- ological main findings were described. Facial neuromonitoring was performed using the same device by an electrophysiologist. The monitor sensitivity was set at 100 mV, and a stimulating probe was used whenever needed. Results Progressively decreasing low-amplitude baseline values were usually obtained as the level of anesthesia increased, with isolated oscillations possibly related to some degree of voluntary muscular activity. These oscillations could be easily distinguished from those of the surgical manipulation or electrical stimulation of the nerve, which tended to be of much greater amplitude and shorter latency, occurring during specific surgical steps. Conclusion With a surgical team with proper procedural knowledge and broad expertise regarding the technique, intraoperative facial nerve monitoring under local anesthesia with sedation seemed both feasible and reliable. Thus, the need for intraoperative neuromonitoring should not be an obstacle for otologic procedures under less aggressive anesthetic management.

ABSTRACT

Introduction: The anatomy of the temporal bone is complex due to the large number of structures and functions grouped in this small bone space, which do not exist in any other region in the human body. With the difficulty of obtaining anatomical parts and the increasing number of ear, nose and throat (ENT) doctors, there was a need to create alternatives as real as possible for training otologic surgeons. Objective: Developing a technique to produce temporal bone models that allow them to maintain the external and internal anatomical features faithful to the natural bone. Methods: For this study, we used a computed tomography (CT) scan of the temporal bones of a 30-year-old male patient, with no structural morphological changes or any other pathology detected in the examination, which was later sent to a 3D printer in order to produce a temporal bone biomodel. Results: After dissection, the lead author evaluated the plasticity of the part and its similarity in drilling a natural bone as grade "4" on a scale of 0 to 5, in which 5 is the closest to the natural bone and 0 the farthest from the natural bone. All structures proposed in the method were found with the proposed color. Conclusion: It is concluded that it is feasible to use biomodels in surgical training of specialist doctors. After dissection of the bone biomodel, it was possible to find the anatomical structures proposed, and to reproduce the surgical approaches most used in surgical practice and training implants (AU)

ABSTRACT

ABSTRACT INTRODUCTION: Transcanal myringoplasty has the advantages of demanding lower operative time and minimal external incisions. It can be performed using the microscopic or endoscopic approach. In the last decade, the use of endoscopes in ear surgery has increased significantly. This technique may allow "around the corner" visualization of small recesses, through narrow spaces, without the aid of canalplasty in unfavorable ear canals. OBJECTIVE: To describe a case series of transcanal endoscopic myringoplasty performed in a university service. The characteristics, advantages, and disadvantages of this technique are also discussed. METHODS: A case series study, based on the chart review of patients submitted to transcanal endoscopic myringoplasty in the period from January of 2012 to October of 2014. RESULTS: Data from 22 patients were analyzed. Tympanic perforation closure three months after surgery was observed in 86.4% of all patients. There was statistically significant improvement in pure tone average thresholds after surgery (p < 0.001). CONCLUSION: Transcanal endoscopic myringoplasty is a feasible, safe, and effective procedure; it can be an alternative to microscopic surgery.


Resumo Introdução: A miringoplastia realizada por via transcanal possui como vantagens a maior rapidez do procedimento e menor incisão externa, podendo ser realizada com auxílio de microscópio ou endoscópio. Na última década tem sido observado um aumento do uso de endoscópios na cirurgia otológica. Essa técnica pode permitir melhor visibilização de espaços encobertos e estreitos, sem necessidade canaloplastia em meatos desfavoráveis. Objetivo: Descrever uma série de casos de miringoplastia endoscópica transcanal, em um serviço universitário, discutindo suas particularidades, vantagens e desvantagens. Método: Estudo de série de casos, baseado na revisão de prontuários dos pacientes submetidos a miringoplastia com uso exclusivo de endoscópio rígido, no período de Janeiro de 2012 a Outubro de 2014. Resultados: Foram analisados os dados de 22 pacientes. Na otoscopia pós-operatória, foi observado fechamento da perfuração timpânica em 86,4% dos pacientes, após 3 meses da intervenção. Para a amostra estudada, foi observada melhora funcional estatisticamente significante da média dos limiares tonais (PTA) após a cirurgia (p < 0,001). Conclusão: A miringoplastia endoscópica transcanal é um procedimento seguro, factível e efetivo, podendo ser realizado como alternativa à cirurgia microscópica.

ABSTRACT

Objective Evaluate the feasibility of an adequate exposure with anatomical preservation of labyrinth structures through retrosigmoid transmeatal approach (RSA) in surgeries for resection of acoustic neuromas/vestibular schwannomas (VS). Method Thirty patients underwent surgical resection and were preoperatively evaluated with fine slice high definition CT scans and 3D-MRI volumetric reconstructions. Extension of internal auditory canal (IAC) opening during surgery was measured using 3 mm right-angle calibrated hook and neuronavigation parameters. Postoperatively, the extension of IAC opening and integrity of the labyrinth were confirmed through preoperatively images procedures. Results The preoperative length of IACs varied between 7.8 and 12.0 mm (mean 9.3 mm, SD 0.98, 95%CI 8.9 to 9.6, and median 9.0 mm). Postoperative images demonstrated adequate opening of the IAC and semicircular channels integrity. Conclusion A complete drilling of the posterior wall of IAC through the RSA is feasible and allows direct visualization of the IAC-fundus without damaging the semicircular canals. .


Objetivo Avaliar a possibilidade de exposição adequada preservando anatomia das estruturas labirínticas pelo acesso retrosigmóide-transmeatal (RSA) nas ressecções de schwannomas do vestibular (VS). Método Trinta pacientes foram submetidos à ressecção cirúrgica e avaliados no pré-operatório com tomografias de alta definição e reconstruções de ressonância magnética 3D. A extensão da abertura do conduto auditivo interno (CAI) foi medida e confirmada com parâmetros de neuronavegação. No pós-operatório, a extensão da abertura e a integridade do labirinto foram confirmadas por imagens de tomografia computadorizada. Resultados A extensão do CAI no pré-operatório apresentou variação de 7,8-12 mm (média 9,3 mm, DP 0,98, IC95% de 8,9-9,6 e mediana 9 mm). Imagens pós-operatórias demonstraram abertura adequada do IAC e integridade dos canais semicirculares. Conclusão A abertura completa da parede posterior do CAI pelo RSA é possível e permite a visualização direta do fundo do conduto sem prejudicar os canais semicirculares. .

ABSTRACT

INTRODUÇÃO: Orelha proeminente, popularmente conhecida como orelha em abano, é uma afecção muito frequente em nosso meio. Constitui a deformidade mais comum da cabeça e pescoço, prevalecendo em aproximadamente 5% da população em geral. O trabalho tem como objetivo demonstrar que, com a junção de técnicas cirúrgicas simples, é possível corrigir as deformidades e obter um ótimo índice de satisfação dos pacientes. MÉTODO: Um total de 60 pacientes de ambos os sexos, entre 11 e 40 anos foram submetidos à otoplastia bilateral entre fevereiro de 2009 e dezembro de 2010. RESULTADOS: Em todos os casos se realizou otoplastia bilateral. Não houve casos de hematomas, infecção de sítio cirúrgico ou cicatriz hipertrófica. Cicatrizes visíveis ou granulomas de corpo estranho na face posterior da orelha foram constatados em 5 casos (8,3%). Houve 1 caso de condrite. O índice de deformidade residual com 1 ano de pós-operatório ocorreu em 3 casos, sendo todos bilaterais. Recidiva total foi presenciada em 1 caso (1,7%). Após um ano da cirurgia, 56 pacientes (93,3%) consideraram o resultado como bom e estavam satisfeitos, 3 pacientes sofreram reintervenção por deformidade residual e em 1 caso ocorreu a recidiva total, em que o mesmo não desejou correção. CONCLUSÃO: O presente estudo vem demonstrar que a associação das técnicas de Mustardè com a de Furnas traz alto grau de satisfação, baixo índice de complicações, podendo ser realizada com tranquilidade em nível ambulatorial e com baixo custo.


INTRODUCTION: Prominent ears, popularly known as bat ears, are the most common deformity of the head and neck, occurring in approximately 5% of the general population. This study aims to demonstrate that, with the use of simple surgical techniques, it is possible to correct the deformity and achieve optimal patient satisfaction. METHOD: A total of 60 patients of both sexes, aged between 11 and 40 years, underwent bilateral otoplasty between February 2009 and December 2010. RESULTS: In all cases, bilateral otoplasty was performed. There were no cases of hematomas, surgical site infection, or hypertrophic scars. In 5 cases (8.3%) visible scars or foreign body granulomas were found in the posterior surface of the ear. Chondritis occurred in one patient. Bilateral residual deformity occurred in 3 cases at 1 year post-surgery. Total recurrence was observed in 1 case (1.7%). After one year of surgery, 56 patients (93.3%) considered the result as good and were satisfied, 3 patients underwent reintervention for residual deformity, and total recurrence occurred in 1 case, which the patient did not wish to correct. CONCLUSION: The present study demonstrates that concurrent use of the Mustardé and Furnas otoplasty techniques results in a high degree of satisfaction and a low rate of complications. The procedure can easily be performed at the outpatient level and at a low cost.

ABSTRACT

Poucos trabalhos desde a década de 70 foram realizados a fim de elucidar a prova calórica em alterações da orelha média, apesar de inúmeras controvérsias que este exame pode trazer em estruturas anatômicas tão distintas. Na mastoidectomia radical, estes estudos são mais escassos. OBJETIVO: Este estudo teve como objetivo analisar os achados da estimulação calórica a ar em indivíduos com mastoidectomia radical unilateral sem queixas de tontura. MATERIAL E MÉTODO: Estudo prospectivo, realização da estimulação calórica a ar em 36 indivíduos sem queixas vestibulares, sendo 21 com cirurgia de mastoidectomia aberta unilateral e 15 sem nenhuma alteração na orelha média ou externa. RESULTADOS: 80,95% dos indivíduos apresentaram respostas assimétricas na prova calórica frias, sendo as respostas maiores do lado da mastoidectomia aberta. Em 72,73%, o mesmo efeito ocorreu com a prova calórica quente. Na análise das quatro estimulações, encontrou-se assimetria das provas quente e frias em 81,82% dos casos. Em 47,61%, foi encontrada estimulação paradoxal da prova calórica quente. CONCLUSÃO:As respostas nistágmicas do lado da mastoidectomia aberta foram maiores se comparadas com o lado saudável. A estimulação paradoxal da prova calórica quente foi um achado frequente. Não foram encontradas respostas hipofuncionantes.


Since the 1970s, few studies have been conducted to elucidate the use of caloric tests on middle ear disorders, despite the many controversies that this test may produce in anatomical structures that are so distinct. In cases of mastoidectomy, such studies are even rarer. OBJECTIVE: This study aims to analyze the findings from air caloric stimulation done in individuals submitted to unilateral radical mastoidectomy without complaints of dizziness. MATERIALS AND METHOD: Thirty-six individuals without vestibular complaints were enrolled in this prospective study. Air caloric stimulation was offered to all subjects. Twenty-one individuals had undergone unilateral open mastoidectomy and 15 did not present any middle or outer ear abnormalities. RESULTS: 80.95% of the individuals presented asymmetrical responses in the cold caloric test, with greater response on the side of the open mastectomy. In 72.73% of the subjects the same effect was observed in the hot caloric test. The four stimulation modes revealed asymmetries in both hot and cold tests in 81.82% of the cases. Paradoxical stimulation was observed in 47.61% of hot caloric tests. CONCLUSION: Nystagmic responses on the side of the open mastoidectomy were greater than on the healthy side. Paradoxical stimulation in caloric tests was a frequent finding. No hypofunctioning responses were found.

ABSTRACT

El tratamiento de la otitis media crónica colesteatomatosa en los niños es controversial y difícil. Nos propusimos caracterizar a pacientes pediátricos con colesteatomas extensos e infección activa, así como identificar hallazgos otoscópicos y quirúrgicos, complicaciones, microbiología, eficacia del tratamiento antimicrobiano y afectaciones funcionales auditivas. Se realizó un estudio descriptivo prospectivo con 12 pacientes, en edades entre 4 y 15 años, operados mediante técnica abierta combinada con timpanoplastia y osiculoplastia entre el 2001 y el 2004. La evolución de los pacientes fue seguida hasta los 3 años después de la cirugía. Los hallazgos más frecuentes fueron la perforación epitimpánica posterior marginal (41,6 por ciento), lesión osicular total (50 por ciento), facial timpánico dehiscente y erosión del canal semicircular horizontal (45,4 por ciento). Las complicaciones intratemporales fueron las más frecuentes (50 por ciento). Se realizó reconstrucción tímpano-osicular a 8 pacientes y los resultados auditivos fueron satisfactorios en el 66,6 por ciento, mientras que la respuesta al antimicrobiano utilizado fue eficaz en el 100 por ciento. El uso de la técnica quirúrgica abierta unida a una correcta estrategia antibiótica es lo indicado en los niños con colesteatomas extensos y con infección activa.


The treatment of in children is controversial and difficult. We proposed ourselves to characterize pediatric patients with extensive cholesteatomas and active infection, as well as to identify otoscopic and surgical findings, complications, microbiology, efficiency of the antimicrobial treatment and functional auditive affections. A descriptive and prospective study was conducted among 12 patients aged 4-15 that were operated on by open technique combined with tympanoplasty and ossiculoplasty from 2001 to 2004. The evolution of the patients was followed during 3 years after surgery. The most common findings were posterior marginal epytimpanic perforation (41.6 percent), total ossicular injury (50 percent), tympanic facial dehiscence and erosion of the horizontal semicircular canal (45.4 percent). The intratemporal complications were the most frequent (50 percent). Timpano-ossicular reconstruction was performed in 8 patients, and the hearing results were satisfactory in 66.6 percent, whereas the response to the antimicrobial agent used was efficient in 100 percent of the cases. The use of the open surgical technique together with a correct antibiotic strategy is what is indicated in children with extensive cholesteatomas and active infection.

ABSTRACT

Introducción: Las intervenciones quirúrgicas del oído medio por colesteatoma tienen por objetivo prioritario la erradicación de la enfermedad, logrando en ocasiones conservar o mejorar la audición de estos pacientes. La aticotomía con antroexclusión es una cirugía conservadora que permite la eliminación de un colesteatoma atical manteniendo una anatomía cercana a la normal. Objetivo: Este trabajo busca determinar los cambios auditivos en pacientes sometidos a este procedimiento quirúrgico. Material y método: Se realiza un estudio transversal con audiometrías a pacientes sometidos a aticoantrostomía con antroexclusión entre los años 2000 y 2005. Se registran datos individuales, hallazgos intraoperatorios y valores audiométricos pre y posoperatorios. Resultados: Se incluyen 18 pacientes, edad promedio de 48 años, 61 por ciento de sexo femenino. La diferencia ósea-aérea preoperatoria promedio es de 38 dB (10-51 dB), mientras la posoperatoria es de 33 dB (18-50 dB). El 50 por ciento de los pacientes obtiene un cierre posoperatorio inferior a 30 dB. No existen cambios significativos con respecto a umbrales de vías óseas o aéreas. Conclusiones: La aticoantrostomía es un procedimiento quirúrgico que permite erradicarla enfermedad y preservar la audición de los pacientes. En nuestra serie existe una conservación de la audición, lo que constituye una ventaja con respecto a otras alternativas quirúrgicas.


Introduction. The primary aim of middle ear surgical intervention due to cholesteatoma is the elimination of the disease, while conserving or in some cases improving the patient's hearing ability. Atticostomy with antrum exclution is a conservative surgery that allows attic cholesteatoma removal, maintaining a relatively normal anatomy. Aims. The main goal of this study is to characterize the audiological changes in patients that underwent this surgical procedure. Material and methods. Audiometries were performed to patients that had atticostomy with antrum exclution, between years 2000 and 2005. Individual data, intra-surgery findings, and audiometric data prior and post surgery were recorded. Results. Results from 18 patients, average age 48 years old, 61% females, are presented. Pre surgical average difference between air and bone conduction was 38dB (10-51 dB), whereas post surgical difference was 33 dB (18-50). Fifty percent of patients reached a post surgical level lower than 30 dB. There were no significant changes related to air or bone conduction thresholds. Conclusions. Atticoantrostomy is a surgical procedure that allows both disease elimination and hearing preservation. In our series, hearing was preserved, which represents an advantage over other surgical alternatives.

ABSTRACT

Objetivo: describir los resultados obtenidos con la colocación de dos prótesis estapediales a pacientes sometidos a estapedotomía por otosclerosis. Tipo de estudio: descriptivo y retrospectivo de revisión de casos. Métodos: se utilizaron prótesis de titanio y de teflón-platino para el cierre de la diferencia entre las curvas ósea y aérea (gap) producido por la otosclerosis. Se revisaron 70 casos intervenidos en el Hospital de San José entre el 2002 y 2005, por tres cirujanos. Se utilizo técnica de pequeña fenestración realizada con perforadores manuales; 48 casos cumplieron con los criterios. Se excluyeron los casos de revisión, aquellos con anomalías anatómicas o datos inadecuados pre o postquirúrgicos. Se midió el gap óseo-aéreo con audiometría de tonos puros en cuatro frecuencias y el umbral límite de pérdida auditiva neurosensorial, tomando como base para evaluar los resultados el PTA (promedio tonal auditivo). Resultados: se agruparon 33 casos con prótesis de teflón y 15 de titanio. El cierre del gap óseo-aéreo menor o igual a 10 db fue del 80% para los casos de titanio y del 76% para los de teflón. La pérdida auditiva neurosensorial fue baja para ambos grupos sin diferencia significativa. Discusión: los resultados fueron similares para ambos grupos, pero se observó que la prótesis de titanio fue levemente superior. Los resultados descritos concuerdan con los reportados en la literatura, que muestran un rango en el cierre del gap óseo-aéreo menor de 10 db del 71% al 94%. El número pequeño de casos o la predilección por una de las prótesis puede influenciar el resultado descrito.

ABSTRACT

As relações entre as diversas estruturas nobres e vitais que se apresentam na intimidade do osso temporal constituem ainda hoje um grande desafio para o cirurgião otológico. Os estudos micro-anatômicos do mesmo se encontram entre as grandes armas na busca deste entendimento. OBJETIVO: Estudar as correlações anatômicas entre o canal carótico e a cóclea, e a ocorrência de deiscências do mesmo junto à cavidade timpânica. MATERIAL E MÉTODO: Estudo microscópico de 122 ossos temporais humanos. RESULTADOS As distâncias médias entre o canal carótico e os giros cocleares foram: no local de menor distância 1,05mm; no giro basal, 2,04mm; no giro médio, 2,32mm; e no giro apical, 5,7mm. A ocorrência de deiscências do canal carótico na cavidade timpânica foi de 35,2 por cento. CONCLUSÃO: A pequena distância entre estruturas cocleares e o canal carótico, e a alta prevalência de deiscências do mesmo na cavidade timpânica nos relembram o desafio com o qual o cirurgião otológico se depara ao atuar sobre o osso temporal.

ABSTRACT

Las orejas prominentes o en ASA son causas de tratamiento quirúrgico. Se realizó un estudio en el Servicio de Cirugía Maxilofacial del Hospital General Clinicoquirúrgico Docente Aleida Fernández Chardiet de Güines, con el fin de modificar las técnicas descritas por otros autores para la formación anatómica del antihélix y sustituir el uso de suturas de anclaje por la aplicación del tisuacryl, lo que logra variaciones faciales de conformidad para el paciente. Fueron tratados quirúrgicamente 36 pacientes; la edad predominante fue la de 9 años (28 por ciento); al sexo el masculino correspondió el 61 por ciento; la afección anatómica más frecuente resultó el aumento del ángulo concho mastoideo (56 por ciento), seguida por la pérdida bilateral del antihélix (36 por ciento). No se reportan recidivas en los pacientes operados ni complicaciones como reacción a cuerpo extraño y pericondritis, que pudieran manifestarse por la utilización de hilos de sutura. La adhesión del pabellón auricular en lecho receptor fue satisfactoria, se disminuyó el tiempo de vendaje y desaparecieron quejas de oído reducido, comezón y el olor a sangre vieja en las vendas(AU)


The prominent or akimbo ears require surgical treatment. A study was conducted at the Maxillofacial Surgery Service of "Aleida Fernández Chardiet" General Clinical and Surgical Teaching Hospital so as to modify the techniques described by other authors for the anatomical formation of the antihelix and for substituting the use of anchorage suture by the application of tisuacryl, which allow facial variations satisfying the patient. 36 patients were surgically treated. 9 years old was the predominating age (28 percent). 61 percent were males, and the most frequent anatomical affection was the increase of the mastoideal looped angle (56 percent), followed by the bilateral loss of the antihelix (36 percent). Neither relapses in the patients operated on nor complications, such as reaction to a foreign body and perichondritis that may manifest when suture thread is used, were reported. The adhesion of the auricular pavilion in the receptor bed was satisfactory. The bandage time was reduced and the complaints about reduced ear, itching and smell of old blood in the bandages disappeared(AU)

ABSTRACT

La otitis media crónica (OMC) es una enfermedad que puede causar diversas y graves complicaciones, entre las cuales se encuentra el absceso cerebeloso. Se publica el caso de una paciente de sexo femenino, de 12 años de edad, con antecedentes de OMC derecha de 5 años de evolución y mala adherencia al tratamiento. Previamente hospitalizada una semana en el mes de agosto de 2001, por un cuadro de regudización de su patología de base y laberintitis secundaria, reingresa un mes más tarde por una nueva complicación de su OMC, caracterizada esta vez por signos de focalización cerebelosa. Se solicita una tomografía computada (TC) y una resonancia nuclear magnética (RMN), exámenes que revelan la presencia de un absceso cerebeloso. Debido a lo anterior, se realiza cirugía de drenaje complementada con cirugía de su patología ótica y antibioticoterapia. Es dada de alta en buenas condiciones generales

ABSTRACT

El objetivo de este artículo es hacer una breve descripción de la programación en implante coclear, las estrategias de procesamiento, y el rol que juega en el proceso de rehabilitación. Está dirigido a todas aquellas personas involucradas en el proceso (médicos, cirujanos, audiólogas, fonoaudiólogas, padres y maestros) para que conozcan los objetivos e importancia de la programación en el proceso. Uno de los aspectos que diferencia la rehabilitación con el implante coclear de aquella que se realiza con prótesis auditivas convencionales es la complejidad del sistema, de su funcionamiento y la importancia del ajuste inicial y posterior del procesador de palabra a las características de cada usuario. Al respecto es importante anotar que la experiencia en el manejo de diversos sistemas y sus modos de programación, y del manejo de numerosos usuarios de diversas edades permite adquirir la habilidad y criterio para poder responder a las exigencias que demanda el uso de este sistema

ABSTRACT

Se propone en este trabajo una técnica quirúrgica para el tratamiento de la atelectasia timpánica. La cirugía consiste en la resección de toda la porción retraída en atelectasias grado 2 o mayores, dejando una perforación. En vista de la rapidez de cierre espontáneo de esta perforación (x: 4,7 semanas), se coloca además un tubo de ventilación en el remanente timpánico para intentar evitar una nueva retracción. En un período de dos años, se efectuó una timpanectomía en 79 pacientes (88 oídos), obteniéndose un grupo de 50 oídos con seguimiento promedio de 12,1 meses (rango: 4-28 meses). Se analizó la última otoscopía de cada paciente. De los 50 oídos operados, 34 tenían un tímpano normal, cerrado y sin retracción. En 9 casos, el tímpano se retrajo nuevamente después del cierre espontáneo, y en 6 había una perforación. De estos 6 casos perforados, en 4 el tímpano inicialmente cerró, reperforándose después, y sólo en 2 casos (4 por ciento) no hubo cierre espontáneo. Los buenos resultados anatómicos y funcionales obtenidos hacen de la timpanectomía una técnica a considerar en el tratamiento de las retracciones timpánicas

ABSTRACT

The purpose of this study was to evaluate the effectiveness of regular otologic care on the long-term outcome in patients with cleft palates. We report the otoscopic and audiologic findings of 50 patients who were followed regularly at our center for an average of 15.4 years. All these patients had their cleft palates repaired by the same surgical team and all ears were examined by one of the authors under the microscope and a chart review completed. Thirty eight patients had at least one tube placement. The physical abnormalities noted were tympanosclerosis (36%), retraction of tympanic membrane (TM) (20%), atrophy of TM (15%), perforation (11%), PE tube in situ (11%), thick TM (6%) and PE tube in middle ear (1%). The examination was normal in 36%. A conductive loss was noted in 18% and sensorineural loss in 3%. The results of this study support the concept of regular otologic care for cleft palate patients even when they are overtly asymptomatic.

ABSTRACT

Acute otitis media (AOM) and otitis media with effusion (OME) in children can present with a variety of middle ear effusions (MEE). Even though the character of the effusion may vary, the underlying pathogenesis is often similar. In the last decade, there has been an abundance of new information in the fields of immunobiology and immunochemistry to explain the chronicity of MEE. There are also studies examining the efficacy of vaccination and immunoprophylaxis for recurrent AOM. Diagnosis of otitis media (OM) in a child can be difficult but good visualization by pneumatic otoscopy improves the accuracy of diagnosis of OME. The development of increasing bacterial resistance to antimicrobial therapy reinforces the need to be more rational in treating AOM and OME. The variability of the natural history and the long term sequelae of OME makes medical management more difficult. All children with chronic MEE should have audiologic evaluation. Surgery is recommended should the condition be refractory to medical therapy or if the complications of MEE develop.
