Value of Endoscopy in Surgical Procedures to Stapedial Region

Abstract

Objectives: Evaluate the role of endoscopic approaches during exclusive or combined (microscopic and endoscopic) procedures to stapedial region, particularly in difficult cases or in anatomic abnormalities. Methods: From 2009 to 2014, 56 endoscopic exclusive or combined (microscopic and endoscopic) approaches to the stapedial region were performed at the otolaryngology department, University Hospital of Modena. Operations performed were stapedoplasties or explorative tympanotomies for conductive hearing loss. Video, patient charts, and operative reports from surgeries were reviewed in February 2014. Cases in which stapedial abnormalities were identified were included and analyzed in the present study. Results: In 8 cases a malformed stapes was identified. Of those, 6 were eventually treated, while in 2 cases, after a diagnosis was made, a conservative attitude was chosen. Under endoscopic view, precise procedures under direct view were made possible, even in very delicate and hidden regions. Conclusions: Whether chosen as a pure explorative tool, or as the main operatory visualization modality, endoscopy can guarantee very good visualization of the stapedial region, and may help in diagnosing and fixing altered stapedial conditions.
