From the results and complications seen in the present study, and analyzing papers from the literature, it is possible to conclude that stapedotomy is a procedure that can be included in residency programs, if there are surgical cases for the residents.
RESUMOOs ceratocistos odontogênicos são apresentados como lesões benignas do complexo maxilomandibular, de grande potencial de crescimento e de grande destruiçäo óssea podendo, quando em múltiplas apresentações, serem associados à "Síndrome de Gorlin", existindo, para tanto, duas teorias para o seu desenvolvimento: uma delas a partir de remanescentes da lâmina dentária, e outra a partir da proliferação de células da camada basal ou do epitélio oral para a mandíbula ou maxila. Os ceratocistos odontogênicos são lesões de caráter geralmente assintomáticos, sendo comumente descobertos em exames radiográficos panorâmicos ou periapicais de rotina. Suas formas de tratamento estão relacionadas ao seu grande potencial recidivante. O presente trabalho tem como objetivo o relato de caso clínico de uma jovem de quatorze anos de idade, em que um ceratocisto odontogênico paraqueratinizado na maxila foi retirado cirurgicamente por enucleação. Tal técnica foi escolhida uma vez que a retirada completa do cisto em questão não representava complicações dos pontos de vista dental e/ou anatômico; e facilitava o estudo integral da lesão com relação ao exame anatomohistopatológico, analisando ainda seus aspectos clínicos, histopatológicos e radiográficos.Termos de indexação: Síndrome do nevo basocelular.

Introduction Inverted papilloma is a rare benign tumor of the nasal fossa, which usually originates from its lateral wall. Only 5% of cases demonstrate exclusive sinus involvement. Primary sphenoid sinus involvement is even rarer. Although considered a benign lesion, the tumor has a potentially invasive nature and has also been found to have an associated malignancy rate of 7 to 15%.
Objectives To report a case of inverted nasal papilloma originating in a rare location: the sphenoid sinus.
Resumed Report a 56-year-old woman, presented to our outpatient clinic complaining of frontal headache, occasional otalgia and recent forgetfulness. She was initially evaluated by a neurologist and then submitted to a head magnetic resonance imaging. A lesion was found to be filling both sphenoid sinuses. Sinus computed tomography showed an opacified sphenoid sinus with apparent bony integrity. The patient underwent sphenoidotomy through a transnasal endoscopic approach. A bleeding papillomatous lesion was identified. A biopsy was performed and histopathologic study suggested inverted papilloma. The lesion was then completely resected. The patient has been followed for 60 days after surgery; no signs of recurrence were found upon flexible nasofibroscope examination.
Conclusion Inverted Papilloma exclusively involving the sphenoid sinus is a rare entity. Non specific symptomatology and Clinical presentation make this kind of tumor a diagnostic and therapeutic challenge. The Endoscopic Sphenoidotomy has been the treatment of choice. Close follow-up is required in order to detect possible recurrences and malignant transformation.
