We use hydroxyapatite prosthesis for the reconstruction of the ossicular chain in stapes surgery. In this study, we report a case series of endoscopic ear surgery using a basket-type hydroxyapatite prosthesis. METHODS: We retrospectively examined 8 cases of endoscopic transcanal stapes surgery using hydroxyapatite prostheses. We evaluated the postoperative results and complications. RESULTS: The average postoperative air-bone gaps were within 10 dB in all cases. Postoperative sensorineural hearing loss was not observed in any case. There was an intraoperative complication with the chorda tympani in 1 patient. We were able to preserve the chorda tympani of all patients, including this case. Postoperative transient dizziness and transient taste disorder were observed in 50% of cases. No other complications, including facial nerve palsy, tympanic membrane perforation, or postoperative infection, were observed. CONCLUSIONS: The postoperative results and complications were comparable to those of surgery under a microscope. The hydroxyapatite prosthesis could be a possible alternative for the piston-type titanium or polytetrafluoroethylene prosthesis.
