Objective measurement of the deviated nose and a review of surgical techniques for correction.

Although many surgical techniques have been introduced, there are few clinical studies investigating postoperative results in crooked nose deformity. The aim of this study is to discuss the surgical choices for specific deformities and to report the long-term quantitative surgical results of our cases. One hundred and twenty cases (38 women, 82 men) with crooked noses (48 I-shaped, 72 C-shaped) operated on by the authors were included in the study.

Contralateral normal ear after mastoid surgery: evaluation by otoacoustic emissions (mastoid drilling and hearing loss).

Mastoid drilling can cause transient hearing loss in the contralateral normal hearing ear.
