Clinical and imaging features of middle ear hairy polyps / 中华耳鼻咽喉头颈外科杂志

Objective: To collect the clinical cases of middle ear hairy polyp, and to summarize the imaging features. Methods: We retrospectively analyzed the clinical data of four cases middle ear hairy polyp confirmed by surgical and pathologic between January 2007 and January 2020 at the Affiliated Eye & ENT Hospital of Fudan University. There were three females, one male, with two left ears and two right ears, aged from 1 to 59 years. The CT and MRI imaging of the patients, and the corresponding clinical manifestations were analyzed. Results: Hairy polyps originated from tympanum in one case, originated from Eustachian tube in two cases, exhibiting recurrent otorrhea without evident inducement. The other case, hairy polyps originated from the Eustachian tube pharyngeal orifice and protruded into the nasopharyngeal cavity, with pharynx discomfort and aural fullness, endoscope showed offwhite polypoid mass with a little hair. All the four cases presented polypoid soft tissue masses on CT and MRI imaging, containing soft tissue wall and a large amount of adipose tissue, with soft tissue in the center of the mass which liked the core, and enhanced. MRI showed stratified arrangement of fat and soft tissue in the wall of the mass. Four cases all had surgical treatment, postoperative pathology examination presented that hair follicles, mature sebaceous glands and other skin appendages were found under squamous epithelium. A large amount of adipose tissue, part of muscle tissue, cartilage tissue, and some fibro-collagenous tissue were proliferated in the mass, accompanied by collagen degeneration. Conclusion: The middle ear hairy polyps has imaging characteristics, the polypoid soft tissue mass usually looks smooth and contains a large amount of adipose tissue, with a soft tissue in the center, and can be suggestively diagnosed by CT and MRI.

Cáncer de nasofaringe, una revisión de la literatura / Nasopharyngeal Cancer, a literature review

Resumen Introducción: El cáncer de nasofaringe es una patología poco común que tiene gran impacto en la calidad de vida de los pacientes. Con el advenimiento de nuevos esquemas de tratamiento se ha logrado mejorar el pronóstico con un menor índice de morbilidad. Esta revisión describe la perspectiva actual del cáncer de nasofaringe, basado en la literatura reciente y la disponibilidad de recursos para su tratamiento en una institución médica de Medellín, Colombia. Materiales y Método: Se realizó una búsqueda bibliográfica que incluyó artículos desde 1986 hasta 2018 en diferentes bases de datos como MEDLINE, EBSCO y LILACS. Se incluyó literatura escrita en inglés o español, utilizando como términos MESH neoplasias de nasofaringe, diagnóstico y terapéutica. Resultados: La evaluación diagnóstica oportuna del cáncer de nasofaringe es de vital importancia al proporcionar una estrategia de tratamiento efectiva con menor morbimortalidad. Según la experiencia institucional de los autores, en las etapas clínicas tempranas, se sugiere la radioterapia radical como modalidad única y en etapas intermedias-avanzadas los tratamientos combinados con quimioterapia-radioterapia concomitante o secuencial dependiendo de cada paciente y quimioterapia única en pacientes metastásicos a distancia. Conclusiones: Acorde con el análisis de la literatura y evidencia existente, las estrategias utilizadas son adaptadas a los alcances de la institución como ente de alto nivel en el sector salud. La cirugía representa un papel relevante en la enfermedad recurrente resecable ya sea con técnica endoscópica o abierta. Es importante recordar que la morbilidad postoperatoria no es inocua, y en ocasiones sobrepasa el beneficio obtenido.

Introduction: Nasopharyngeal cáncer is a rare disease that has a huge impact on the quality of life. Survival rates are steadily improving due to new treatments with a lower morbidity index. This review describes the current perspective of nasopharyngeal cancer, based on recent literature and the availability of resources for treatment in the different specialties of an institution in Medellin, Colombia. Materials and Method: A literature review was carried out, including articles from 1986 to 2017 in different databases such as MEDLINE, EBSCO and LILACS. Written literature in English or Spanish was included, using MESH terms as Nasopharyngeal, diagnostic and therapeutic neoplasms. Results: Nasopharyngeal cancer timely diagnostic is of vital importance. According to the institutional experience, in early clinical stage radiotherapy is suggested as a single modality. Intermediate stages treatments options are concurrent chemo radiotherapy or sequential radiotherapy according to each patient case. In distant metastatic stage single chemotherapy is used. Conclusions: According to existing evidence strategies used are adapted to the scope of the institution as a high-level entity in health sector. Surgery represents a relevant role in recurrent resecable disease with either endoscopic or open technique. It is important to remember that postoperative morbidity is not harmless, and sometimes exceeds the benefit obtained.

Small cell neuroendocrine carcinoma of the nasopharynx: a rare case report

Small cell neuroendocrine carcinoma rarely appears primarily in the head and neck and exhibits aggressive behavior with a poor prognosis. The pathologist has a significant role in the diagnosis, and a consensual treatment still does not exist. The authors report the case of a middle-aged male patient who presented repeated episodes of massive epistaxis. The diagnostic work-up disclosed the diagnosis of small cell neuroendocrine carcinoma of the nasopharynx. The patient was treated with chemotherapy followed by radiotherapy. Imaging examinations performed after the end of treatment showed apparent complete remission of the disease. The patient was kept under active surveillance with no signs of local relapse or distant metastasis after 4 years of follow-up.

Immediate impact of rapid maxillary expansion on upper airway dimensions and on the quality of life of mouth breathers

OBJECTIVE: To assess short-term tomographic changes in the upper airway dimensions and quality of life of mouth breathers after rapid maxillary expansion (RME). METHODS: A total of 25 mouth breathers with maxillary atresia and a mean age of 10.5 years old were assessed by means of cone-beam computed tomography (CBCT) and a standardized quality of life questionnaire answered by patients' parents/legal guardians before and immediately after rapid maxillary expansion. RESULTS: Rapid maxillary expansion resulted in similar and significant expansion in the width of anterior (2.8 mm, p < 0.001) and posterior nasal floor (2.8 mm, p < 0.001). Although nasopharynx and nasal cavities airway volumes significantly increased (+1646.1 mm3, p < 0.001), oropharynx volume increase was not statistically significant (+1450.6 mm3, p = 0.066). The results of the quality of life questionnaire indicated that soon after rapid maxillary expansion, patients' respiratory symptoms significantly decreased in relation to their initial respiratory conditions. CONCLUSIONS: It is suggested that RME produces significant dimensional increase in the nasal cavity and nasopharynx. Additionally, it also positively impacts the quality of life of mouth-breathing patients with maxillary atresia. .

OBJETIVO: avaliar, por meio de tomografias, as mudanças em curto prazo nas vias aéreas superiores e na qualidade de vida em pacientes respiradores bucais, após expansão rápida da maxila (ERM). MÉTODOS: foram avaliados 25 pacientes respiradores bucais com atresia maxilar, com idade média de 10,5 anos, por meio de tomografia computadorizada de feixe cônico (TCFC) e questionário padronizado de qualidade de vida submetido aos pais/responsáveis, antes e imediatamente após a ERM. RESULTADOS: a ERM promoveu uma expansão, de forma semelhante e significativa, tanto na largura do soalho nasal anterior (2,8mm, p < 0,001) quanto na largura do soalho nasal posterior (2,8mm, p < 0,001). No volume aéreo da nasofaringe e fossas nasais, houve aumento significativo (+1646,1mm3 p < 0,001); entretanto, no volume aéreo da orofaringe, houve aumento não significativo (+1450,6 mm3 p = 0,066). Os resultados do questionário de qualidade de vida indicaram melhora significativa na qualidade de vida dos pacientes após a ERM, em comparação ao questionário inicial. CONCLUSÕES: a ERM promoveu aumento dimensional significativo nas fossas nasais e na nasofaringe, bem como melhorou significativamente a qualidade de vida dos pacientes. .

Rhinosporidiosis of the Neck: A Rare Occurrence.

Rhinosporidiosis is a chronic granulomatous disease caused by a fungus Rhinosporidium seeberi, It frequently involves the nasopharynx and presents as a painless, friable, polypoidal growth hanging anterior to the nares or posteriorly into the pharynx. Th e lesions appear pink with minute white dots, which give it a strawberry-like appearance. Histopathologically, the organisms appear as sporangia containing large numbers of round or ovoid endospores. Several drugs have been tried, but Dapsone has proven to be most eff ective. In the present case, the lesion was seen on the anterior border of the mandible which is a very rare site for this infection. Th e growth was pedunculated and proliferative mimicking an aggressive lesion. On histology, also a rare fi nding of involvement of lymph nodes by the sporangia was noted.

Primary Nasopharyngeal Tuberculosis.

Tuberculous infection of the upper respiratory tract is an uncommon clinical condition and in that nasopharyngeal involvement is struck with rarity per se. This condition is often prevalent in people of low socioeconomic strata living in endemic areas, especially in developing countries. It has a silent and indolent course and most commonly mimicks nasopharyngeal carcinoma in its clinical presentation. In absence of concurrent pulmonary involvement, it is often misdiagnosed or diagnosed only after the biopsy has been taken. Nevertheless, high index of suspicion is required on part of the clinician to diagnose this comparatively rare entity.

Imaging Finding of Malignant Melanoma of Eustachian Tube with Extension to Middle Ear Cavity: Case Report

We report a case of malignant melanoma of Eustachian tube with extension to the middle ear cavity and nasopharynx in a 51-year-old woman who presented with right ear fullness. Computed tomography showed a soft tissue mass in the middle ear cavity and causedthe widening and eroding of the bony eustachian tube. Magnetic resonance imaging showed well enhancing mass in eustachian tube extending nasopharynx to middle ear cavity. A biopsy of the middle ear cavity mass revealed a malignant amelanotic melanoma.

Manifestações neoplásicas em rinofaringe / Neoplasic manifestation in rhinopharynx

As neoplasias primárias de nasofaringe são raras na infância e adolescência. Sintomas como obstrução nasal persistente, cefaleia, epistaxes recorrentes e abaulamento paranasal ou de palato são comuns à maioria delas e podem ser confundidos com outras doenças infecciosas ou alérgicas.As neoplasias mais frequentes na faixa etária pediátrica são os rabdomiossarcomas, os linfomas não Hodgkin, o estesioneuroblastoma, o carcinoma de nasofaringe e o angiofibroma juvenil. A biópsia ou ressecção da lesão quando possível, seguida de tratamento quimio e radioterápico, quando indicado, compõem o tratamento destas neoplasias.

Clinicopathological study of non-neoplastic lesions of nasal cavity and paranasal sinuses.

An analysis of cases presenting as mass in nasal cavity (NC), paranasal sinuses (PNS), and nasopharynx (NP) was done over a period of 7 years in Jawaharlal Nehru Medical College, Aligarh. A provisional diagnosis was made after clinical assessment and radiological investigations, but final diagnosis was made after histopathological examination. The incidence of masses in NC, PNS, and NP was 34.3 cases per year, non-neoplastic lesions constituted 60% of these cases and their incidence was 20.7 cases per year. All the cases were carefully examined histopathologically and it was found that the region was affected by a variety of non-neoplastic lesions. Among 240 cases, 145 were non-neoplastic and 95 were neoplastic The lesions in the decreasing order of frequency were - nasal polyp, rhinoscleroma, tuberculosis, fungal infection, fibrous dysplasia, ossifying fibroma, cysts, nasal glioma, and cemento-ossifying fibroma. NP was involved by a range of neoplastic lesions; however, no non-neoplastic lesion was seen in this region.

Diagnóstico por imagem dos tumores da nasofaringe / Imaging diagnosis of nasopharyngeal tumors

A nasofaringe é a parte mais superior das vias aéreas superiores. Seu limite superior é a base do osso esfenóide e occipital, situa-se anteriormente às duas primeiras vértebras cervicais e à frente do clivo. Seus limites laterais são formados pelas margens do músculo constritor superior da faringe e pela fáscia faringobasilar, recessos faríngeos, toro tubário e tuba auditiva. O limite inferior é um plano horizontal que passa pelo palato duro e pelo músculo palatofaríngeo. Anteriormente, comunica-se com a cavidade nasal via coana posterior. Mede cerca de 2,0 cm de diâmetro ântero-posterior e cerca de 4,0 cm de extensão crânio-caudal. O carcinoma de células escamosas compreende aproximadamente 70 por cento a 98 por cento de todas as neoplasias malignas da nasofaringe em adultos. Este tipo de tumor apresenta alta incidência na população asiática, sendo mais comum entre os homens e o terceiro mais comum entre as mulheres. A manifestação clínica do carcinoma da nasofaringe depende do tamanho da lesão e da sua localização, sendo que as lesões de pequenas dimensões são geralmente assintomáticas. A tomografia computadorizada e a ressonância magnética desempenham papel essencial e complementar no estadiamento e no tratamento dos pacientes portadores de câncer da nasofaringe.

The nasopharynx is located in the upper aerodigestive tract. Its roof is formed by the basisphenoid, basiocciput and the anterior aspect of the first two cervical vertebrae, in front of the clivus. The lateral walls are formed by the margins of the superior constrictor muscle and the pharyngobasilar fascia, pharyngeal recess, torus tubarius and pharyngeal opening of auditory tube. The inferior margin of the nasopharynx is a horizontal plane passing through the hard palate and palatopharyngeal muscle. Anteriorly, it is in direct continuity with the nasal cavity through the posterior choanae. It is approximately 2.0 cm in anteroposterior diameter and about 4.0 cm in craniocaudal extent. Squamous cell carcinoma accounts for about 70 percent to 98 percent of nasopharyngeal malignant lesions found in adults. This tumor presents a high incidence in Asians, most frequently in men, and is the third most frequent cancer in women. The clinical presentation of this disease depends on the size and site of the lesion, with small-sized lesions being asymptomatic. Computed tomography and magnetic resonance imaging play essential and complementary roles in the staging and treatment of patients with nasopharyngeal cancer.

Nasopharyngeal tuberculosis: a case report presenting with neck mass

Tuberculosis is a common infectious disease. Nasopharyngeal involvement is a rare finding. We present a case [33-year old female] of known chronic renal failure with primary nasopharyngeal tuberculosis. The only manifestation of disease was bilateral cervical lymphadenopathy. There were no tuberculosis lesions in other organs. Diagnosis was made based on result of pathological examination of biopsy. Improvement was obtained by anti tuberculosis therapy. Tuberculosis must be considered in differential diagnosis of nasopharyngeal mass

Escolares submetidos a videonasofaringoscopia na escola: achados e aceitação / Schoolchildren submitted to nasal fiber optic examination at school: findings and tolerance

OBJETIVO: Verificar a aceitação da videonasofaringoscopia por crianças, no ambiente escolar, para avaliação de vegetações adenoideanas e determinar a sua prevalência nessa população MÉTODO: Estudo transversal realizado em amostra proporcional (n = 368) de escolares da primeira série do ensino fundamental de Aracaju (SE), com idades entre 6 e 13 anos, submetidos a videonasofaringoscopia flexível. Todas se submeteram à mesma rotina de exame, feito na própria escola, sem a necessidade de contenção ou qualquer tipo de sedação. RESULTADOS: As crianças que foram submetidas a avaliação nasofibroscópica aceitaram bem o procedimento, permitindo a adequada avaliação das cavidades do nariz e nasofaringe. A prevalência de hipertrofia adenoideana grau I foi de 50,6 por cento, a de grau II foi de 35,1 por cento e a de grau III foi de 14,3 por cento. As hipertrofias adenoideanas graus II e III apresentam maior número de sintomas obstrutivos. CONCLUSÃO: A videonasofaringoscopia flexível pode ser realizada, com excelente aceitação, fora do ambiente hospitalar ou consultório, como mostra este estudo realizado em ambiente escolar, indicando que sua utilização pode ser mais ampla, tornando-a mais acessível a um maior número de pessoas. A prevalência dos três graus de hipertrofia adenoideana encontrada em Aracaju difere de alguns estudos por ter sido realizada em crianças não triadas para sintomas respiratórios.
