There are a variety of techniques for treating chronically discharging radical mastoid cavities. The purpose of this article is to report the preliminary results of an original technique for reconstruction of the posterior auditory canal using a titanium net combined with porous hydroxyapatite coating. Titanium is fixed with two screws to the mastoid tip and zygomatic root to prevent the risk of implant dislocation. Eight patients with chronically discharging radical mastoid cavities that failed medical management underwent reconstruction of the mastoid cavity using this technique. After surgery, all cases had rapid healing and good aeration of the middle ear and mastoid. One tympanic membrane reperforated, and no extrusion of the prostheses were detected clinically or on computed tomography scanning. The minimum postoperative follow-up period has been 12 months (range 12-48 months). To date, there has been no evidence of cholesteatoma recurrence. The preliminary results remain encouraging. Larger series and longer follow-up, however, are advisable to prove real validity.

Abstract
There are a variety of techniques for treating chronically discharging radical mastoid cavities. The purpose of this article is to report the preliminary results of an original technique for reconstruction of the posterior auditory canal using a titanium net combined with porous hydroxyapatite coating. Titanium is fixed with two screws to the mastoid tip and zygomatic root to prevent the risk of implant dislocation. Eight patients with chronically discharging radical mastoid cavities that failed medical management underwent reconstruction of the mastoid cavity using this technique. After surgery, all cases had rapid healing and good aeration of the middle ear and mastoid. One tympanic membrane reperforated, and no extrusion of the prostheses were detected clinically or on computed tomography scanning. The minimum postoperative follow-up period has been 12 months (range 12-48 months). To date, there has been no evidence of cholesteatoma recurrence. The preliminary results remain encouraging. Larger series and longer follow-up, however, are advisable to prove real validity.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
