Atresia de coana unilateral: reporte de un caso pediátrico / Unilateral coana atresia. A pediatric case report

La atresia de coanas se caracteriza por la obliteración de la abertura nasal posterior. Es la anomalía congénita más frecuente de las fosas nasales. Tiene una incidencia de 1 cada 5000 a 7000 neonatos, con predominio en el sexo femenino. Puede presentarse en forma aislada o asociada a otros síndromes como el CHARGE (coloboma [C], malformaciones cardíacas [H], atresia de coanas [A], retraso psicomotor y/o en el crecimiento [R], hipoplasia de genitales [G], malformaciones auriculares y/o sordera [E, por su sigla en inglés]). Las manifestaciones clínicas son la obstrucción nasal, cianosis y dificultad respiratoria desde el nacimiento cuando es bilateral. Las atresias unilaterales se caracterizan por insuficiencia ventilatoria nasal y rinorrea unilateral, y pueden pasar inadvertidas. El diagnóstico se realiza mediante endoscopia y estudios por imágenes. El tratamiento es quirúrgico; existen diferentes técnicas y vías de abordaje. Se presenta el caso de un paciente masculino de 7 años con atresia unilateral de coana derecha con resolución microendoscópica, colocación de tutor externo, con buena resolución.

Choanal atresia is characterized by obliteration of the posterior nasal opening. It is the most common congenital anomaly of the nasal passages. It has an incidence of 1 in 5000 to 7000 newborns; predominantly female. It can occur in isolation or in association with other syndromes such as CHARGE (coloboma [C], cardiac malformations [H], choanal atresia [A], psychomotor and/or growth retardation [R], genital hypoplasia [G], atrial malformations and/or deafness [E]. Clinicallypresents nasal obstruction, cyanosis and respiratory distress from birth when bilateral, unilateral atresias are characterized by nasal ventilatory insufficiency and unilateral rhinorrhea, which may go unnoticed. Diagnosis is made by endoscopy and imaging tests. Treatment is surgical, with different techniques and approaches.A 7-year-old male patient is presented with unilateral atresia of the right choana with microendoscopic resolution, placement of an external tutor, with good resolution.

Evaluación de la obstrucción nasal por métodos subjetivos y pico flujo inspiratorio nasal en niños y adolescentes con rinitis crónica / Assessment of nasal obstruction by subjective methods and peak nasal inspiratory flow in children and adolescents with chronic rhinitis

Introducción. La obstrucción nasal (ON) es el síntoma más molesto de la rinitis crónica (RC). Los estudios que correlacionaron métodos subjetivos y objetivos de ON realizados en niños y adultos produjeron resultados contradictorios. Objetivos. Analizar la correlación entre escalas subjetivas de ON con determinaciones de pico flujo inspiratorio nasal (PFIN) y comparar la valoración subjetiva de la ON y el PFIN en niños según su edad. Población y métodos. Participaron pacientes con RC. Se estimó la correlación entre la evaluación subjetiva de la ON mediante una escala visual análoga (ON-EVA, por su sigla en inglés) y la Escala de evaluación de los síntomas de obstrucción nasal (NOSE, por su sigla en inglés) y medición del flujo aéreo nasal pre- y posvasoconstrictor, mediante PFIN. Se analizaron las diferencias entre los grupos de 8 a 11 años y los de 12 a 15 años para la valoración subjetiva de la ON y PFIN. Resultados. Se incluyeron 79 pacientes entre 8 y 15 años. No se comprobó correlación entre ON-EVA y PFIN antes y después del vasoconstrictor (r = -0,19; p = 0,11 y r = -0,18; p = 0,15 respectivamente) ni entre NOSE y PFIN basal (r = -0,23; p = 0,07). Hubo diferencias en el PFIN entre niños de 8-11 años y 12 a 15 años (p = <0,0001), pero no se demostraron diferencias en la percepción subjetiva por ON-EVA (p = 0,7591). Conclusión. No se demostró correlación entre puntajes subjetivos de ON y PFIN en niños y adolescentes con RC. Los niños mayores perciben menos la ON que los de menor edad. Las escalas subjetivas de ON no reemplazan su medición con PFIN en pacientes con rinitis.

Introduction. Nasal obstruction (NO) is the most irritating symptom of chronic rhinitis (CR). The results of studies that correlated subjective and objective methods of NO in children and adults were contradictory. Objectives. To analyze the correlation between subjective NO scales and peak nasal inspiratory flow (PNIF) measurements and compare the subjective NO assessment and PNIF in children by age. Population and methods. Participants were patients with CR. The correlation between the subjective NO assessment using a visual analog scale (NO-VAS) and the Nasal Obstruction Symptom Evaluation (NOSE) and nasal airflow measurement pre- and post-vasoconstrictor administration using the PNIF was estimated. The differences in the subjective NO assessment and PNIF between children aged 8-11 years and 12-15 years were analyzed. Results. A total of 79 patients aged 8-15 years were included. No correlation was established between the NO-VAS and the PNIF before and after vasoconstrictor administration (r = -0.19; p = 0.11 and r = -0.18; p = 0.15 respectively) or between the NOSE and the baseline PNIF (r = -0.23; p = 0.07). Differences were observed in the PNIF between children aged 8-11 years and 12-15 years (p = < 0.0001), but there were no differences in the subjective perception assessed with the NO-VAS (p = 0.7591). Conclusion. No correlation was demonstrated between the subjective NO score and the PNIF in children and adolescents with CR. Older children have a lower perception of NO than younger ones. Subjective NO scales cannot replace the PNIF measurement in patients with rhinitis

Atresia congénita bilateral de coanas en una adolescente: reporte de un caso / Congenital bilateral choanal atresia in an adolescelent: a case report

La atresia congénita de coanas se caracteriza por la presencia de placas que obliteran la comunicación entre la cavidad nasal y la nasofaringe desde el nacimiento. Se considera como incompatible con la vida cuando la condición es bilateral. El siguiente es el caso de una paciente femenina, de 17 años, sin síndromes asociados, con obstrucción y descarga nasal anterior bilateral, asociado a respiración oral desde el periodo neonatal. El diagnóstico de atresia bilateral de coanas fue confirmado por medio de endoscopía nasal y tomografía computarizada (TC). La imagen confirmó la presencia de placas atrésicas de composición mixta. La paciente recibió tratamiento quirúrgicamente por vía transnasal con resección de las placas y modelado de neocoana.

Congenital choanal atresia is characterized by the presence of plates obliterating the communication between the nasal cavity and the nasopharynx from birth. If bilateral, this condition is incompatible with life. This following is the case of a 17-year-old female patient, without associated syndromes, with bilateral nasal obstruction and anterior discharge, associated to oral breathing, starting in her neonatal period. The diagnosis of bilateral choanal atresia was confirmed by nasal endoscopy and computed tomography (CT) scan, due to the presence of atretic plates of mixed composition. The patient was surgically treated with plate resection and modeling of a neochoana by means of a transnasal surgical approach.

Effects of oral isotretinoin therapy on the nasal cavities / Efeitos nasais da terapia com isotretinoína oral

Abstract Introduction Isotretinoin (13 cis-retinoic acid) is the most effective treatment for acne vulgaris and is the only treatment option that can provide either remission or a permanent cure. Objective The aim of this study was to use both subjective and objective methods to assess the nasal complaints of patients with severe acne who received oral isotretinoin therapy. Methods Fifty-four subjects were enrolled in the study. All the subjects were assessed with subjective (NOSE and VAS questionnaires) and objective (rhinomanometry and saccharine) tests to determine the severity of their nasal complaints. Results The mean severity scores (min: 0; max: 100) for nasal dryness/crusting and epistaxis were 0.47 ± 1.48 (0-5); 0.35 ± 1.30 (0-5) at admission, 3.57 ± 4.45 (0-10); 2.26 ± 4.71 (0-20) at the first month, and 4.28 ± 6 (0-20); 2.26 ± 4.71 (0-20) at the third month of the treatment respectively. Total nasal resistance of 0.195 ± 0.079 (0.12-0.56) Pa/cm3/s at admission, 0.21 ± 0.084 (0.12-0.54) Pa/cm3/s at the first month, and 0.216 ± 0.081 (0.14-0.54) Pa/cm3/s at the third month. Conclusion Oral isotretinoin therapy can cause the complaint of nasal obstruction. In addition, nasal complaints, such as dryness/crusting and epistaxis, significantly increase in patients during the therapy schedule.

Melanoma mucoso nasal: una enfermedad impredecible / Mucosal melanoma of the nasal cavity: an unpredictable disease

RESUMEN El melanoma mucoso maligno es un tumor neuroectodérmico de menos del 5% de las neoplasias nasosinusales. Es un tumor de mal pronóstico clásicamente su promedio de supervivencia a cinco años es cercano al 28% y 17,5% a diez años, siendo aún peor cuando existe metástasis en cuello. Se presentan a continuación dos casos de melanoma mucoso en cavidad nasal y senos paranasales, el primero mujer 58 años con melanoma septal llevada a septotomía abierta más quimioterapia y radioterapia adyuvante, con recurrencia en cuello submaxilar derecho tratada con vaciamiento supraomohioideo actualmente sin recurrencia; el segundo hombre de 40 años con antecedente de resección melanoma septal quien presenta nuevo melanoma región etmoidal izquierda luego de su primera cirugía y es llevado a resección endoscópica transnasal sin tratamiento adyuvante por decisión del paciente.

ABSTRACT Sinonasal mucosal melanoma is a neuroectodermic tumor account less 5% of nasosinusal tumors. It has a poor prognosis with a five-year average survival near 28% and 17.5% to 10 years; if neck metastasis is even worst. Here we present two clinical cases. First one a woman 58 years old with septal melanoma who receives an open septectomy with chemotherapy and radiotherapy with submaxillary recurrence treated with supraomohyoid neck dissection. The second case, a man 40 years old with previous septal melanoma surgery who has an ethmoid sinus recurrence and receives transnasal endoscopic surgery without adjuvant therapy by patient desire.

Adenoma pleomorfo originado en pared lateral nasal: reporte de un caso clínico / Pleomorphic adenoma of lateral nasal wall: a case report

RESUMEN El adenoma pleomorfo constituye la neoplasia benigna más frecuente de las glándulas salivales mayores, y puede también presentarse en otros sitios con mucha menor frecuencia como orofaringe, hipofaringe y nasofaringe. El adenoma pleomorfo intranasal es muy infrecuente y los casos descritos en la literatura local se refieren a tumores septales. Se presenta un caso clínico de una paciente que consulta por obstrucción nasal unilateral a derecha asociado a, epistaxis y epífora ipsilateral con estudio imagenológico y biopsia que sugiere adenoma pleomorfo de la pared lateral nasal. Se realiza revisión bibliográfica al respecto.

ABSTRACT The pleomorphic adenoma is the most frequent benign neoplasm of the major salivary glands. It can also present itself in other places with much less frequency such as oropharynx, hypopharynx and nasopharynx. The intranasal pleomorphic adenoma is very unusual and the cases described in the local literature address septal tumors. A clinical case is presented of a patient who consulted for unilateral right nasal obstruction associated with epistaxis and ipsilateral epiphora with imaging study and biopsy suggesting pleomorphic adenoma of the lateral nasal wall. A bibliographic review is made in this regard.

An often neglected area in crooked nose: middle turbinate pneumatization / Uma área frequentemente negligenciada no nariz torto: pneumatização da concha média

Abstract Introduction: Crooked or deviated nose is a deviation of the nose from the straight vertical position of the face. Extensive pneumatization of the middle turbinate, also called concha bullosa or bullous middle turbinate (BMT) is known to be one of the possible etiologic factors in nasal obstruction, recurrent sinusitis, and headache. There is no study concerning a link between BMT and crooked nose. Objective: To investigate the association between crooked nose and the presence of a BMT. Methods: A total of 199 patients who underwent open septorhinoplasty were retrospectively analyzed. Preoperative paranasal Computerized Tomography (CT) findings, preoperative photodocumentation, and anterior rhinoscopic examination findings were documented. Of the 199 patients, 169 were found to meet the criteria and were included in the study. CT scans were examined to note the presence of BMT, inferior turbinate hypertrophy, and septum deviation (SD). SDs and crooked noses were classified. Results: Ninety-four of 169 patients (56%) presented a crooked nose deformity and seventy-five of 169 patients (44%) presented a straight nose. While 49 (52%) crooked nose patients had a bulbous and extensive BMT, 20 patients with straight nose (26.6%) had a BMT. A statistically significant relationship was found between the presence of crooked nose and BMT, regardless of the side of the disease (p = 0.011). Conclusion: This study revealed a link between crooked nose and BMT.

Resumo Introdução: O nariz torto ou o nariz com desvio é um nariz com um desvio da posição vertical reta da face. A pneumatização extensa da concha média, também chamada de concha bolhosa ou concha média bolhosa (CMB), é conhecida por ser um dos possíveis fatores etiológicos da obstrução nasal, sinusite recorrente e cefaleia. Não há estudo relativo a uma associação entre CMB e nariz torto. Objetivo: Investigar a associação entre o nariz torto e a presença de CMB. Método: Foram analisados retrospectivamente 199 pacientes que se submeteram a septorrinoplastia aberta. Achados pré-operatórios paranasais à tomografia computadorizada (TC), fotodocumentação pré-operatória e exame rinoscópico anterior foram registrados. Dos 199 pacientes, observou-se que 169 atendiam aos critérios e foram incluídos no estudo. As TC foram examinadas para observar a presença de CMB, hipertrofia de conchas inferiores e desvio de septo (DS). Os DS e narizes tortos foram então classificados. Resultados: Dos 169 pacientes, 94 (56%) apresentavam uma deformidade de nariz e 75 (44%) apresentavam nariz reto. Enquanto 49 (52%) pacientes com nariz torto tinham CMB extensa, 20 pacientes com nariz reto (26,6%) tinham CMB. Uma relação estatisticamente significativa foi encontrada entre a presença de nariz torto e CMB, independentemente do lado da doença (p = 0,011). Conclusão: Este estudo revelou uma relação entre o nariz torto e CMB.

Fibroangioma nasofaríngeo juvenil: experiencia de 15 años en el Hospital Barros Luco Trudeau / Juvenile nasopharyngeal fibroangioma: the experience of 15 years in Hospital Barros Luco Trudeau

Introducción: El fibroangioma nasofaríngeo juvenil es un tumor vascular benigno localmente agresivo, que afecta casi exclusivamente la nasofaringe de adolescentes de sexo masculino. Su manejo es complejo dada su extensión, naturaleza vascular y sus frecuentes recurrencias. Objetivo: Mostrar la experiencia de 15 años en fibroangioma juvenil en nuestro centro. Material y método: Estudio descriptivo retrospectivo de los pacientes con diagnóstico de ingreso de fibroangioma nasofaríngeo juvenil al Servicio de Otorrinolaringología del Hospital Barros Luco Trudeau entre los años 1997 y 2011, caracterizando al grupo de estudio en cuanto a características clínico-demográficas, vasos aferentes, relación entre etapa tumoral y vascularización, manejo terapéutico, complicaciones y recurrencias. Resultados: Se obtuvo un total de 20 pacientes, todos de sexo masculino, con un promedio de edad de 13,9 años. El síntoma de presentación más frecuente fue la epistaxis a repetición y obstrucción nasal presente en el 90% y 80%, respectivamente. Todos los pacientes se estudiaron con tomografia computarizada y recibieron embolización arterial preoperatoria. La mayoría de los tumores fueron de tipo II (65%) y III (20%), según clasificación de Radkowski. La técnica quirúrgica más empleada fue abierta (57,8%). Radioterapia en un caso. El vaso aferente principal fue la maxilar interno ipsilateral en el 100%. Todos los fibroangiomas etapa III eran además irrigados por la arteria carótida interna. Se encontró 20% de persistencia y 15% de recidiva. Conclusión: Nuestros resultados concuerdan con la gran mayoría de las series publicadas en la literatura. Epistaxis recurrente, obstrucción nasal y tumor nasal unilateral deben hacernos sospechar de esta patología en un adolescente masculino. El tratamiento de elección es la cirugía con embolización preoperatoria. La vía de abordaje endoscópica presenta menor morbilidad posoperatoria en pacientes con estadios I y II de Radkowski. Todos los fibroangiomas con compromiso intracraneano, presentan irrigación también del sistema carotideo interno.

Introduction: Nasopharyngeal Fibroangioma is a locally aggressive benign vascular tumor. Its management is complex given its size, vascular nature and its frequent recurrences. Aim: To show the experience of 15 years in Juvenile Fibroangioma in our center. Material and method: Retrospective descriptive study of patients admitted with a diagnosis of Juvenile Fibroangioma Nasopharyngeal in the Department of Otolaryngology Hospital Barros Luco Trudeau between 1997 and 2011. Results: A total of 20 patients was obtained. The most common presenting symptom was recurrent epistaxis and nasal obstruction present in 90% and 80% respectively. The most common surgical technique was open (57.8%). Radiotherapy in one case. The main afferent vessel was the ipsilateral internal maxillary in 100%. All Fibroangioma stage III were also supplied by the internal carotid artery. 20% of persistence and 15% of recurrence was found. Conclusion: Recurrent epistaxis, nasal obstruction and unilateral nasal tumor should raise the suspicion of this disease in a male teenager. The treatment of choice is surgery with preoperative embolization. The route of endoscopic approach has less postoperative morbidity in patients with stage I and II of Radkowski. All Fibroangioma with intracranial commitment, have also the internal carotid irrigation system.

Difficult septal deviation cases: open or closed technique? / Difficult septal deviation cases: open or closed technique?

Abstract Introduction: The aim of this study is to compare the functional aspects of open technique (OTS) and endonasal septoplasty (ENS) in "difficult septal deviation cases". Methods: 60 patients with severe nasal obstruction from S-shaped deformities, multiple deformities, high deviations etc. were included in the study. The OTS was used in 30 patients and the ENS was performed in 30 patients. The Nasal Obstruction Symptom Evaluation (NOSE) scale was administered preoperatively and at first month following surgery. Patients were also evaluated for pain postoperatively with Visual Analog Scale (VAS). Results: The mean NOSE score was decreased 62.5-11.0 in the OTS group and 61.3-21.33 in the ENS group. Improvement of the symptoms following the two surgical techniques is similar and no statistically significant difference was found between both techniques. Also there was no statistically significant difference in postoperative pain between the OTS and ENS groups evaluated by VAS. Conclusion: ENS is as successful as the OTS in management difficult septal deviation cases. In patients with severe septal deformities type of the surgical technique should be selected according to the surgeon's experience and the patient's preference.

Resumo Introdução: O objetivo deste estudo é comparar os aspectos funcionais da septoplastia entre a técnica aberta (STA) e a endonasal (SEN) em "casos difíceis de desvio de septo nasal". Método: Foram incluídos 60 pacientes com obstrução nasal devido a deformidades em forma de S, múltiplas deformidades, desvios altos, etc. A STA foi usada em 30 pacientes e a SEN em 30. A escala de avaliação do sintoma de obstrução nasal (NOSE) foi administrada no pré-operatório e no primeiro mês após a cirurgia. Os pacientes também foram avaliados com Escala Visual Analógica (EVA) para dor no pós-operatório. Resultados: O escore médio de NOSE foi reduzido de 62,5-11,0 no grupo da STA e de 61,3-21,33 no grupo da SEN. Houve melhora dos sintomas com as duas técnicas cirúrgicas e não foi encontrada diferença estatisticamente significativa entre elas. Também não houve diferença estatisticamente significativa nos graus de dor no pós-operatório que tenha sido avaliada pela EVA entre o grupo de STA e o de SEN. Conclusão: De acordo com nossos dados, a SEN é tão bem-sucedida quanto a STA no tratamento de casos difíceis de desvio de septo nasal. Em pacientes com deformidades septais graves, o tipo de técnica cirúrgica deve ser escolhido de acordo com a experiência do cirurgião e a preferência do paciente.

Mucocele maxilar secundario a cirugía ortognática: reporte de un caso / Maxillary mucocele after an orthognathic surgery: case report

El mucocele es un tumor pseudoquístico poco frecuente en el seno maxilar y una rara complicación de la cirugía ortognática. El caso reportado describe la presentación de un mucocele que afecta parcialmente el seno maxilar y se presenta clínicamente como un tumor nasal. Se trata de una mujer de 44 años que, luego de 12 años de realizarse cirugías ortognáticas, presenta dolor facial y obstrucción de la fosa nasal derecha. La tomografía axial computarizada de senos paranasales revela una masa de contenido líquido que ocupa la mitad inferior del seno maxilar derecho, extendiéndose a la fosa nasal ipsilateral. La paciente es intervenida por vía endoscópica realizándose una marsupialización intranasal y meatotomía media, evolucionando satisfactoriamente en un seguimiento de dos años.

Mucoceles are not often found in the maxillary sinus, and is a rare surgery complication, in this case, orthognathic. This review describes a mucocele that partially occupies the right maxillary sinus, causing a chronic nasal obstruction. This is the case of a 44 year-old female patient, which after 12 years of several orthognathic surgeries, presents facial pain and right nasal obstruction. The paranasal sinus computed tomography reveals a mass with liquid content that occupies the lower part of the right maxillary sinus and compromises the right nasal cavity. The patient was treated with an intranasal marsupialization and a middle meatotomy with endoscopic nasal approach. Evolution was satisfactory two years after the intervention.

Calcinosis tumoral en septum nasal en un paciente con insuficiencia renal crónica dializado. Presentación de un caso / Tumoral calcinosis in nasal septum in a patient with chronic renal failure in dialysis. Presentation of a case

Los trastornos metabólicos ocasionados por la insuficiencia renal y la diálisis para su tratamiento pueden conducir a la precipitación de sales de fosfato cálcico con la consecuente formación de tumores en diversas localizaciones. Estos pueden ser únicos o múltiples, pudiendo ocasionar obstrucción y compresión de distintas estructuras anatómicas con la consecuente alteración funcional. Si bien el manejo clínico de las alteraciones antes citadas es fundamental, la cirugía adquiere relevancia en estas situaciones. Se presenta un caso de Calcinosis Tumoral única ubicada en el tercio anterior del septum nasal, ocasionando obstrucción de la fosa nasal. La tomografía computada orientó el diagnóstico y la resección tumoral completa por vía nasal fue el tratamiento elegido. El informe de anatomía patológica confirma el diagnóstico de Calcinosis Tumoral. A los nueve meses de seguimiento en el postoperatorio no se evidencia recidiva.

Metabolic disorders caused by chronic renal failure and dialysis for its treatment can lead to the precipitation of calcium phosphate salts with the consequent formation of tumors in various locations. These can be single or multiple, and may cause obstruction and compression of different anatomical structures with consequent functional alteration. Although the clinical management of the above mentioned alterations is fundamental, the surgery acquires relevance in these situations. We present a case of unique tumoral calcinosis located in the anterior third of the nasal septum, causing obstruction of the nasal fossa. Computed tomography guided diagnosis and complete tumor resection by nasal route was the treatment chosen. The pathological anatomy report confirms the diagnosis of tumor calcinosis. At nine months post-operative follow-up there was no evidence of tumor recurrence.

Influência do retalho faríngeo sobre a nasalidade e a nasalância na produção de sons nasais em indivíduos com fissura labiopalatina / Influence of pharyngeal flap surgery on nasality and nasalance scores of nasal sounds production in individuals with cleft lip and palate

RESUMO Objetivo: Verificar a influência da cirurgia de retalho faríngeo para a correção da insuficiência velofaríngea sobre a nasalidade e a nasalância da fala na produção de sons nasais de indivíduos com fissura labiopalatina. Métodos Estudo prospectivo realizado com 159 indivíduos com fissura de palato±lábio reparada, de ambos os gêneros, com idades entre 6 e 57 anos. Todos os participantes apresentavam insuficiência velofaríngea residual com indicação para cirurgia de retalho faríngeo e foram submetidos à avaliação perceptivo-auditiva e nasométrica da fala, antes e após (14 meses, em média) a cirurgia de retalho faríngeo. A hiponasalidade foi classificada perceptivamente em ausente ou presente e a nasalância foi determinada por meio do nasômetro, utilizando amostras de fala com sons predominantemente nasais, a fim de se estimar a hiponasalidade. O valor de 43% foi utilizado como limite inferior de normalidade. A nasalidade e a nasalância foram comparadas antes e após a cirurgia (p<0,05). Resultados: A hiponasalidade perceptiva foi observada em 14% dos indivíduos, enquanto que os valores de nasalância sugestivos de hiponasalidade (<43%) foram obtidos em 25% deles após a cirurgia, havendo correlação entre os métodos utilizados. Conclusão A cirurgia de retalho faríngeo influenciou na produção dos sons nasais, causando hiponasalidade em parcela significativa dos indivíduos. A presença deste sintoma de fala pode ser ainda um indicador de obstrução das vias aéreas superiores provocada pelo retalho faríngeo, que deve ser investigada de forma objetiva e criteriosa no pós-operatório.

ABSTRACT Objective To verify the influence of pharyngeal flap surgery on the management of velopharyngeal insufficiency on nasality and speech nasalance on nasal sound production in individuals with cleft lip and palate. Methods Prospective study in 159 individuals with repaired cleft palate±lip, of both genders, aged 6 to 57 years old. All the participants presented residual velopharyngeal insufficiency and were submitted to pharyngeal flap surgery. Perceptual speech evaluation and nasometric assessment were performed before and after (14 months on average) the pharyngeal flap surgery. Hyponasality was rated as absent or present, and nasalance scores were determined by means of nasometer using nasal stimuli, with a cutoff score of 43% used as the lowest limit of normality. Nasality and nasalance were compared before and after surgery (p<0.05). Results On the basis of correlation between both the methods used, perceptual hyponasality was observed in 14% of the individuals, whereas nasalance scores indicating hyponasality (<43%) were obtained in 25% of the patients after surgery. Conclusion Pharyngeal flap surgery influenced the production of nasal sounds, causing hyponasality in a significant proportion of individuals. The presence of this speech symptom can also be an indicator of upper airway obstruction caused by pharyngeal flap, which should be investigated objectively and prudently postoperatively.

Síndrome de nariz vacía / Empty nose syndrome

El síndrome de nariz vacía es una enfermedad de reciente descripción, que no tiene una definición clínica clara. Se puede originar como complicación de la cirugía de resección de cornetes, en especial del inferior. La fisiopatología no está del todo definida, pero es probable que posterior a la resección de cornetes se altere la permeabilidad nasal, interfiriendo con los mecanismos neurosensitivos y con las funciones de los cornetes. Su síntoma principal, es la obstrucción nasal paradójica. El diagnóstico es clínico, basado en los síntomas con los hallazgos de una cavidad nasal amplia posterior a la cirugía nasal. El tratamiento es difícil por lo subjetivo de los síntomas, prefiriendo en un comienzo el tratamiento médico y reservando la cirugía para casos más severos. Lo más importante es la prevención, realizando cirugías lo más conservadora posibles de la anatomía de la cavidad nasal.

The Empty Nose Syndrome is a recently described disease, which has no clear clinical definition. It is a rare complication of turbinate surgery especially in the inferior turbinectomy. The pathophysiology is unclear, but after turbinectomy the nasal patency could be affected and this can interfere with neurosensory mechanisms and functions of the turbinates. The most common symptom is the paradoxical nasal obstruction. The diagnosis is clinical, based on symptoms with the discovery of a wide nasal cavity after nasal surgery. Treatment is difficult because of the subjective symptoms, initially preferring medical treatment and surgery is reserved for more severe cases. Most important is the prevention, being as conservative as possible with the nasal cavity.

Pituitary macroadenoma presenting as a nasal tumor: case report / Macroadenoma hipofisário, apresentando-se como um tumor nasal: relato de caso

CONTEXT: Pituitary macroadenomas are rare intracranial tumors. In a few cases, they may present aggressive behavior and invade the sphenoid sinus and nasal cavity, causing unusual symptoms. In this paper, we report an atypical case of pituitary adenoma presenting as a nasal mass. CASE REPORT: The patient was a 44-year-old woman who had had amenorrhea and galactorrhea for ten months, with associated nasal obstruction, macroglossia and acromegaly. Both growth hormone and prolactin levels were increased. Magnetic resonance imaging showed a large mass originating from the lower surface of the pituitary gland, associated with sella turcica erosion and tumor extension through the sphenoid sinus and nasal cavity. Histopathological analysis demonstrated a chromophobe pituitary adenoma with densely packed rounded epithelial cells, with some atypias and rare mitotic figures. There was no evidence of metastases. CONCLUSION: Macroadenoma invading the nasal cavity is a rare condition and few similar cases have been reported in the literature. This study contributes towards showing that tumor extension to the sphenoid sinus and nasopharynx needs to be considered and investigated in order to make an early diagnosis when atypical symptoms like nasal obstruction are present. .

CONTEXTO: Macroadenomas hipofisários são tumores intracraniais raros. Em alguns casos, podem apresentar comportamento agressivo e invadir o seio esfenoidal e a cavidade nasal, causando sintomas não usuais. Neste relato de caso, descrevemos um caso atípico de adenoma hipofisário manifestando-se como uma massa nasal. RELATO DE CASO: A paciente de 44 anos, do sexo feminino, apresentava amenorreia e galactorreia por 10 meses associando-se a obstrução nasal, macroglossia e acromegalia. Os níveis do hormônio de crescimento e de prolactina apresentaram-se aumentados. Ressonância magnética mostrou uma grande massa originada da superfície inferior da glândula hipofisária associada com erosão da sela túrcica e extensão do tumor através do seio esfenoidal e cavidade nasal. Análise histopatológica demonstrou adenoma hipofisário cromófobo com células epiteliais arrendondadas densamente agrupadas com algumas atipias e escassas figuras de mitose. Não houve evidências de metástase. CONCLUSÃO: O macroadenoma invasivo para a cavidade nasal é uma condição rara e há poucos relatos similares descritos na literatura. Este trabalho contribui para mostrar que, na presença de sintomas atípicos como a obstrução nasal, a extensão para o seio esfenoidal e para a nasofaringe deve ser considerada e investigada para um diagnóstico precoce. .

Radiographic adenoid evaluation - suggestion of referral parameters / Avaliação radiográfica da adenoide - sugestão de parâmetros de referência

OBJECTIVE: this study aimed to evaluate the usefulness of current radiographic measurements, which were originally conceived to evaluate adenoid hypertrophy, as potential referral parameters. METHODS: children aged from 4 to 14 years, of both genders, who presented nasal obstruction complaints, were subjected to cavum radiography. Radiographic examinations (n = 120) were evaluated according to categorical and quantitative parameters, and data were compared to gold-standard videonasopharyngoscopic examination, regarding accuracy (sensitivity, negative predictive value, specificity, and positive predictive value). RESULTS: radiographic grading systems presented low sensitivity for the identification of patients with two-thirds choanal space obstruction. However, some of these parameters presented relatively high specificity rates when three-quarters adenoid obstruction was the threshold of interest. Amongst the quantitative variables, a mathematical model was found to be more suitable for identifying patients with more than two-thirds obstruction. CONCLUSION: this model was shown to be potentially useful as a screening tool to include patients with, at least, two-thirds adenoid obstruction. Moreover, one of the categorical parameters was demonstrated to be relatively more useful, as well as a potentially safer assessment tool to exclude patients with less than three-quarters obstruction, to be indicated for adenoidectomy. .

OBJETIVO: o objetivo deste estudo foi de investigar a utilidade de medidas radiográficas destinadas à avaliação da tonsila faríngea a serem utilizadas como potenciais parâmetros de encaminhamento. MÉTODOS: crianças de quatro a 14 anos, de ambos os gêneros, que apresentavam queixas referentes à obstrução nasal foram submetidas à radiografia do cavum. Os registros radiográficos (n = 120) foram avaliados de acordo com parâmetros categóricos e quantitativos, e dados resultantes foram comparados ao exame padrão-ouro de videonasofaringoscopia, em relação às suas taxas de acurácia (sensibilidade, valor preditivo negativo, especificidade e valor preditivo positivo). RESULTADOS: os parâmetros radiográficos categóricos apresentaram baixa sensibilidade para a identificação de pacientes portadores de 2/3 de obstrução do espaço coanal. No entanto, alguns destes parâmetros apresentaram especificidades relativamente altas quando 3/4 de obstrução coanal era o ponto de corte de interesse. Dentre as variáveis quantitativas, um modelo matemático se mostrou mais adequado para identificar pacientes com mais de 2/3 de obstrução coanal. CONCLUSÃO: este modelo demonstrou, assim, ser potencialmente útil como método de rastreamento para identificação de pacientes com pelo menos 2/3 de obstrução adenoidiana. Além disso, um dos parâmetros categóricos analisados demonstrou ser relativamente mais útil e potencialmente seguro para eliminar pacientes queixosos com menos de 3/4 de obstrução a serem indicados à adenoidectomia. .

Revisión de 25 casos de papiloma invertido en 8 años / Review of 25 cases of inverted papilloma in 8 years

Introducción: El papiloma invertido es un tumor benigno inusual del tracto nasosinusal, caracterizado por el riesgo de recurrencia y transformación maligna. Objetivo: Nuestro objetivo es describir la serie de casos diagnosticados con papiloma invertido del tracto nasosinusal entre 2002 y 2010. Material y método: Se trata de un análisis retrospectivo de los casos nuevos de papiloma invertido del tracto nasosinusal atendidos en nuestro Hospital entre los años 2002 y 2010. Resultados: Se presentaron 25 casos nuevos de papiloma invertido. Los síntomas tenían en promedio 2 años de evolución, siendo la obstrucción nasal y rinorrea los más frecuentes. La etapificación preoperatoria fue realizada mediante tomografía computarizada en 15 pacientes. El abordaje endoscópico fue el preferido. Cincuenta y seis por ciento de los pacientes correspondía a la etapa 2 de la clasificación de Krause. El promedio de seguimiento fue 29 meses. Durante ese periodo, 4 casos presentaron recurrencia, correspondiendo al 16% de nuestra serie. La mitad de ellos presentó displasia o atipia al momento de la recurrencia. Ocurrió 1 caso de transformación maligna, el cual se presentó como un carcinoma indiferenciado. Conclusión: Las características generales son similares a los reportes internacionales. En nuestro medio los pacientes son diagnosticados en etapas avanzadas de la enfermedad, no obstante, el abordaje endoscópico es el método quirúrgico preferido.

Introduction: Inverted papilloma is an unusual benign tumor of the sinonasal tract, characterized by an important risk of recurrence and malignant transformation. Aim: Our objective is to describe the case series diagnosed with inverted papilloma of the sinonasal tract between the years 2002 and 2010. Material and method: A retrospective analysis of new cases of inverted papilloma of the sinonasal tract treated at our Hospital between the years 2002 and 2010. Results: 25 cases of newly diagnosed inverted papilloma presented in our institution. The symptoms had on average 2 years of evolution, being nasal obstruction and rhinorrhea the most frequent. Preoperative staging by computed tomography (CT) was performed in 15 patients. The endoscopic aproach was preferred as surgical approach. 56% of the patients corresponded to stage 2 of Krause classification. Median folow up was 29 months. During that period, 4 patients had recurrence, corresponding to 16% in our series. Half of these patients had dysplasia or atypia at the time of recurrence. 1 case of malignant transformation ocurred, which presented as an undifferentiated carcinoma. Conclusions: General characteristics were similar to those reported in international reports. In our setting, patients are diagnosed in advanced stages of disease, nevertheless, endoscopic approach is the preferred surgery method.

Respiração oral e alteração de fala em crianças / Oral breathing and speech disorders in children

OBJETIVO: Verificar alterações na fala em crianças respiradoras orais e relacioná-las com o tipo respiratório, a etiologia, o gênero e a idade. MÉTODO: Foram avaliados 439 respiradores orais com idade entre quatro e 12 anos. Considerou-se atraso no desenvolvimento de fala a presença de alterações em crianças acima de cinco anos de idade. As alterações observadas foram interposição de língua (IL), ceceio frontal (CF), troca articulatória (TA), omissões (OM) e ceceio lateral (CL). Relacionou-se etiologia da respiração oral, gênero, idade, tipo respiratório e alterações de fala. RESULTADOS: Alterações de fala foram diagnosticadas em 31,2% dos pacientes sem relação com o tipo respiratório: oral ou misto. Maior frequência de trocas articulatórias e mais de uma alteração de fala ocorreram no gênero masculino. IL foi documentada em 53,3% pacientes, seguida por TA em 26,3% e CF em 21,9%. Concomitância de duas ou mais alterações de fala ocorreu em 24,8% das crianças. CONCLUSÃO: Respirar pela boca pode afetar o desenvolvimento da fala, a socialização e o desempenho escolar. A detecção precoce da respiração oral é essencial para prevenir e minimizar seus efeitos negativos sobre o desenvolvimento global dos indivíduos.

OBJECTIVE: To assess speech alterations in mouth-breathing children, and to correlate Mouth breathing; them with the respiratory type, etiology, gender, and age. METHOD: A total of 439 mouth-breathers were evaluated, aged between 4 and 12 years. The presence of speech alterations in children older than 5 years was considered delayed speech development. The observed alterations were tongue interposition (TI), frontal lisp (FL), articulatory disorders (AD), sound omissions (SO), and lateral lisp (LL). The etiology of mouth breathing, gender, age, respiratory type, and speech disorders were correlated. RESULTS: Speech alterations were diagnosed in 31.2% of patients, unrelated to the respiratory type: oral or mixed. Increased frequency of articulatory disorders and more than one speech disorder were observed in males. TI was observed in 53.3% patients, followed by AD in 26.3%, and by FL in 21.9%. The co-occurrence of two or more speech alterations was observed in 24.8% of the children. CONCLUSION: Mouth breathing can affect speech development, socialization, and school performance. Early detection of mouth breathing is essential to prevent and minimize its negative effects on the overall development of individuals.
