[Mastoid cavity obliteration with allogenic and autologous material].

Introduction: Surgical obliteration is the treatment of choice for symptomatic mastoid cavities. Various methods and materials are available. Allogeneic material is easily available but can lead to wound infections due to rejection, granulation and inflammatory reactions.

Mastoid cavity obliteration leads to a clinically significant improvement in health-related quality of life.

Objective: To assess the change in health-related quality of life (HRQoL) in patients undergoing mastoid cavity obliteration.

Methods: Patients who had undergone canal wall-down mastoidectomy for chronic otitis media with creation of a persistent mastoid cavity and underwent revision tympanomastoid surgery including mastoid cavity obliteration using autologous material were included. Audiological measurements including air conduction (AC) and bone conduction (BC) pure-tone averages (PTA) and the air-bone gap (ABG) were assessed.
