Impact of Partial Mastoid Obliteration on Caloric Vestibular Function in Canal Wall Down Mastoidectomy

Abstract

Our technique of partially obliterating tympanomastoid cavities with autologous bone pâté being covered by cartilage plates results in small cavities with complete epithelialization of all surfaces. Furthermore, obliteration of mastoid cavities confers protection to the labyrinthine organ, thereby reducing postoperative vertigo on caloric stimulation.
