ObjectivesTo demonstrate different techniques in manipulating the chorda tympani nerve during endoscopic stapedotomy for otosclerotic patients.MaterialsTwenty patients presented with clinically diagnosed otosclerosis were randomly selected from outpatient ENT clinic in a tertiary referral Hospital over a period of 2years (2013–2015) for endoscopic stapes surgery.MethodsThis prospective study demonstrates different management modalities of chorda tympani nerve in endoscopic stapes surgery according to the endoscopic anatomical relationship between the length of the chorda tympani nerve and the degree of scutum overhanging the oval window niche structures (endoscopic scutum- chorda tympani relationship).ResultsThree management techniques were carried out to deal with chorda tympani based on its endoscopic anatomical relationship with the scutum (no manipulation, upward-displacement, downward-displacement). All patients had significant improvement of postoperative hearing. Only 2 patients were managed by downward displacement technique had postoperative change in taste sensation and tongue numbness that improved over a period of 6months.Conclusiontrans-Canal fully endoscopic stapedotomy provides feasible and safe handling of the chorda tympani nerve with best postoperative taste sensation preservation.
