Absceso mastoideo como presentación de colesteatoma congénito en preescolar ¿cuál es el origen? / Mastoid abscess as congenital cholesteatoma presentation in a child what is the origin?

Resumen El colesteatoma congénito es una entidad que puede manifestarse con una amplia variedad de síntomas o ser silente durante largo tiempo y constituir un hallazgo incidental. Una vez diagnosticada es importante valorar su extensión y el compromiso de estructuras adyacentes, para lograr una adecuada planificación quirúrgica, eliminando la enfermedad y manteniendo la mejor funcionalidad posible. Se presenta un caso de colesteatoma congénito infantil.

Abstract Congenital cholesteatoma is an entity that can manifest with a wide variety of symptoms or be silent for a long time and constitute an incidental finding. Once diagnosed, it is important to assess the extension to apply the most efficient treatment, eliminating the disease and providing functionality if possible. A case of congenital cholesteatoma in a child is presented.

Recurrence of Cholesteatoma: A Retrospective Study Including 1006 Patients for More than 33 Years

Abstract Introduction Cholesteatomas are benign tumors consisting of skin, and growing inside a retraction pocket in the tympanic membrane. Cholesteatomas can occupy the entirety of the middle ear, and are known for their osteolytic capabilities. Surgery is the only curative treatment for cholesteatomas. Objective To describe the risk of recurrence after first-time surgically-treated middle- ear cholesteatoma (STMEC1) on the island of Funen from 1983 to 2015. Methods Cases of STMEC1 were identified in the Danish National Hospital Register. The medical records were reviewed. Time-to-event analyses were applied. The ears were followed from STMEC1 to a secondary cholesteatoma, emigration, death, or end of follow-up. Results Records from 1,006 patients with STMEC1 were reviewed. A total of 54 patients were submitted to surgery on both ears. The total sample consisted of 1,060 ears with STMEC1; 300 were children's (< 16 years) ears, and 760 were adult's ears. The total observation time was of 12,049 years. The overall estimated proportion with recurrence 5 years after surgery was of 37% in children and of 15% in adults. The older the child was at the first surgery, the risk decreased by 7% per year. In children, canal wall up (CWU) mastoidectomy without obliteration was associated with a hazard ratio for recurrence of 1.9 (95% confidence interval [95%CI]: 1.2-3.0) compared with CWU with obliteration. Conclusion Compared with adults, children were had 2.6 times more risk of recurrence. Procedures performed without mastoidectomy had the lowest risk of recurrence. In children, obliteration was associated with a significantly lower risk of recurrence. However, patients were not randomized regarding the surgical approach; thus, the association between approach and risk of recurrence was likely influenced by confounding factors.

Effects of cavity reconstruction on morbidity and quality of life after canal wall down tympanomastoidectomy / Efeitos da reconstrução da cavidade da timpanomastoidectomia com técnica aberta na morbidade e qualidade de vida

Abstract Introduction: Canal wall down tympanomastoidectomy is commonly used to treat advanced chronic otitis media or cholesteatoma. The advantages of canal wall down mastoidectomy are excellent exposure for disease eradication and postoperative control of residual disease; its disadvantages include the accumulation of debris requiring life-long otological maintenance and cleaning, continuous ear drainage, fungal cavity infections, and the occurrence of dizziness and vertigo by changing temperature or pressure. Objective: To evaluate whether cavity-induced problems can be eliminated and patient comfort can be increased with mastoid cavity reconstruction. Methods: In total, 11 patients who underwent mastoid cavity reconstruction between March 2013 and June 2013 comprised the study group, and 11 patients who had dry, epithelialized CWD cavities were recruited as the control group. The study examined three parameters: epithelial migration, air caloric testing, and the Glasgow Benefit Inventory. Epithelial migration, air caloric testing, and the Glasgow Benefit Inventory were evaluated in the study and control groups. Results: The epithelial migration rate was significantly faster in study group (1.63 ± 0.5 mm/week) than control group (0.94 ± 0.37 mm/week) (p = 0.003, p < 0.05). The mean slow component velocity of nystagmus of the study group (13.33 ± 5.36°/s) was significantly lower when compared to control group (32.11 ± 9.12°/s) (p = 0.018). The overall the Glasgow Benefit Inventory score was −7.21, and the general subscale, physical and social health scores were −9.71, −21.09, and +20.35, respectively in the control group. These were +33.93, +35.59, +33.31, and +29.61, respectively in the study group. All but the social health score improved significantly (0.007, 0.008, 0.018, and 0.181, respectively). Conclusions: Cavity reconstruction improves epithelial migration, normalizes caloric responses and increases the quality of life. Thus, cavity rehabilitation eliminates open-cavity-induced problems by restoring the functional anatomy of the ear.

Resumo Introdução: A timpanomastoidectomia com a técnica Canal Wall Down, ou técnica aberta, é comumente utilizada para tratar otite média crônica avançada ou colesteatoma. As vantagens da mastoidectomia pela técnica aberta são uma excelente exposição para a erradicação da doença e controle pós-operatório da doença residual; suas desvantagens incluem o acúmulo de detritos que requerem manutenção e limpeza otológica ao longo da vida, drenagem contínua da orelha, infecções fúngicas na cavidade e a ocorrência de tonturas e vertigem com alterações de temperatura ou pressão. Objetivo: Avaliar se os problemas induzidos pela cavidade podem ser eliminados e o conforto do paciente aumentado com a reconstrução da cavidade mastoide. Método: No total, 11 pacientes submetidos à reconstrução da cavidade mastoide entre março de 2013 e junho de 2013 constituíram o grupo de estudo, e 11 pacientes com cavidades secas e epitelizadas, operadas pela técnica aberta, foram recrutados como grupo controle. O estudo analisou três parâmetros: migração epitelial, prova calórica com estimulação a ar e o questionário Glasgow Benefit Inventory. A migração epitelial, a prova calórica e o Glasgow Benefit Inventory foram avaliados nos grupos de estudo e controle. Resultados: A taxa de migração epitelial foi significativamente mais rápida no grupo de estudo (1,63 ± 0,5 mm/semana) do que no grupo controle (0,94 ± 0,37 mm/semana) (p = 0,003, p < 0,05). A velocidade média do componente lento do nistagmo no grupo de estudo (13,33 ± 5,36°/s) foi significativamente menor se comparada ao grupo controle (32,11 ± 9,12°/s) (p = 0,018). O escore global do Glasgow Benefit Inventory foi de -7,21 e os escores da subescala geral, saúde física e social foram -9,71, -21,09 e +20,35, respectivamente, no grupo controle. Esses escores foram +33,93, +35,59, +33,31 e +29,61, respectivamente, no grupo de estudo. Todos, exceto o escore de saúde social, melhoraram significativamente (0,007, 0,008, 0,018 e 0,181, respectivamente). Conclusões: A reconstrução da cavidade melhora a migração epitelial, normaliza as respostas da prova calórica e aumenta a qualidade de vida. Assim, a reabilitação da cavidade elimina os problemas induzidos por cavidades abertas ao restaurar a anatomia funcional da orelha.

Carcinoma de osso temporal sem foco metastático primário: relato de caso e revisão de literatura / Carcinoma temporal bone unfocused metastatic primary: case report and literature review

Os tumores do osso temporal são raros e geralmente apresentam sintomas como otorreia, otalgia e hipoacusia, por isso podem ser facilmente confundidos com um processo infeccioso, retardando o diagnóstico e piorando o prognóstico do paciente. KS, 7 anos, masculino. Estado geral: regular. Ao exame: consciente; linfonodos cervicais palpáveis, móveis; massa palpável, imóvel e indolor em topografia retroauricular esquerda; surdez à esquerda e paralisia facial esquerda. Tomografia computadorizada de crânio evidenciou lesão expansiva do osso temporal captante de contraste com extensão para fossa média e posterior do crânio. Realizada complementação radiológica com ressonância de encéfalo, a qual apresentou imagem hipercaptante em T1 contrastado. Nas incidências T2, observa-se edema lobotemporal adjacente à lesão. Exame angiográfico cerebral apresentou obstrução tumoral do seio sigmoide esquerdo. Paciente submetido à mastoidectomia radical esquerda com ligadura e ressecçãodo seio sigmoide esquerdo resultando em ressecção completa lesional. Anatomopatológico e exame imunoistoquímico compatíveis com adenocarcinoma. Encaminhado para terapia oncológica com quimioterapia e radioterapia. Óbito após quatro meses do tratamento neurocirúrgico. O diagnóstico precoce associado com a extensão do tumor acarreta melhor ou pior prognóstico para os pacientes acometidos por essa moléstia.

Tumors of the temporal bone are rare and usually have symptoms such as otorrhea, otalgia and hearing loss and, therefore, can be easily confused with an infectious process delaying diagnosis and worse prognosis. KS, age 7, male. General condition: regular. On examination: conscious, palpable cervical lymph nodes, mobile; palpable mass, painless and property surveying retroauricular left, left deafness and facial paralysis left. Cranial computed tomography showed a lesion of the temporal bone with extensionto the middle fossa and posterior skull that enhance with contrast. Performed complementation with radiological MRI brain image which showed uptake, in contrast T1. Incidences in T2, there is edema temporal lobe adjacent to the lesion. Cerebral angiography showed a tumor obstructing the left sigmoidsinus. Patient underwent left radical mastoidectomy with ligation and resection of the left sigmoid sinus resulting in complete lesional resection. Histopathological and immunohistochemical examination compatible with adenocarcinoma. Referred for cancer therapy with chemotherapy and radiation. Death within four months after neurosurgical treatment. Early diagnosis associated with tumor extension carries a better or worse prognosis for patients affected by this disease.
