Chronic otitis media — Obliterative techniques

Abstract

Early obliteration dates back to Mosher¹in 1911, who employed subcutaneous full thickness postauricular tissues down to the sterno-mastoid muscle to occlude the antrum and epitympanum. He used a superior pedicle which leaves the obliteration material insufficiently supplied by arteries and nerves. Tongues of temporalis muscle have also been brought to mastoid cavity for obliteration but these grafts frequently suffer from insufficient blood and nerve supply and generally contain an insufficient bulk.²
