Abstract
• In this study, preoperative and postoperative ear canal volumes of ears subjected to obliterative radical mastoidectomy were assessed. The measurements were performed using sterile saline solution both at the preoperative stage (V0) and at the early (one year, V1) and the late (five to 13 years, V2) postoperative stages. The mean V0 was 0.8 mL (SD, 0.2 mL); V1, 1.0 mL (SD, 0.3 mL); and V2, 1.2 mL (SD, 0.4 mL). The differences were highly significant. Clinically, the widening of the ear canals was mainly slight and appeared evenly in the epitympanic area and in the posterior ear canal wall. (Arch Otolaryngol 1982;108:208-209)
