Purpose: This study aims to evaluate the surgical outcomes with the use of a combination of the middle temporal artery (MTA) flap and the inferior musculoperiosteal (IMP) flap for mastoid obliteration after canal wall down mastoidectomy.
Methods: Seventy-five patients who have undergone canal wall down mastoidectomy and mastoid obliteration with the MTA and the IMP flaps at a single tertiary hospital were included. Surgical outcomes measured included the creation of a dry mastoid cavity as measured by a previously developed semi-quantitative scale, mastoid cavity epithelization time, rate of revision surgery needed, and rate of recurrent cholesteatoma.
