Transcanal endoscopic treatment of benign middle ear neoplasms.

The application of endoscopic surgery for middle ear pathologies is rapidly increasing. At present, its main application is in the treatment of middle ear cholesteatoma. This report describes the application of this technique as treatment for some benign lesions that may involve the middle ear cleft. A retrospective chart review of six patients who underwent exclusive endoscopic tympanic cavity surgery for benign neoplasms was performed between November 2011 and January 2012. Based on charts, images, and surgical reports, data from the patients were summarized for further consideration. All of the six lesions were in the tympanic cavity without involvement of the mastoid region. An exclusive endoscopic transcanal approach was used in all cases. No patient showed signs or symptoms of pathology recurrence. Endoscopic transcanal excision of benign tympanic cavity neoplasms represents a safe procedure, with minimal morbidity and without external incisions or mastoidectomies.
