ABSTRACT
INTRODUCTION:
Labyrinthine fistula is one of the most frequent complications of cholesteatoma (CHO), occurring in about 8% of cases in the literature. In about 90% of cases, it is located at the level of the lateral semicircular canal, and its clinical manifestation includes vertigo, nystagmus and positive Hennebert and Tullio signs. The management of lateral semicircular canal fistula (LSCF) secondary to CHO classically requires a retroauricular access by performing a canal wall-up (CWU) or canal wall-down (CWD) mastoidectomy. However, in case of a CHO confined to the tympanic cavity causing a LSCF on the ampullar arm, a transcanal exclusive endoscopic approach could be considered.AIMS:
The aim of this study is to describe the feasibility of a transcanal exclusive endoscopic approach in the management of a CHO confined to the tympanic cavity causing a LSCF on the ampullar arm.METHODS:
From January 2019 to December 2020, three patients with LSCF secondary to mesotympanic CHO underwent transcanal exclusive endoscopic ear surgery repair at the Department of Otolaryngology-Head and Neck Surgery, University Hospital of Modena, Italy.RESULTS:
This technique was successfully employed to treat LSCF in all three cases and was planned as a two-stage surgery, performing ossiculoplasty after 12-18 months. Functional outcomes were also satisfactory complete eradication of CHO, hearing preservation and complete resolution of symptoms.CONCLUSIONS:
In case of a CHO confined to the tympanic cavity causing an LSCF on the ampullar arm, a transcanal exclusive endoscopic approach could be considered as a feasible and safe technique.Palavras-chave
