The use of mitomycin-C for respiratory papillomas: clinical, histologic and biochemical correlation.

Objective: To assess the clinical effects of mitomycin-C (MMC) on human papilloma virus (HPV)-infected tissues of the airway.

Methods: We included 10 patients with previous histologic diagnosis of recurrent respiratory papillomas (RRP) in this prospective study, conducted at the Department of Otolaryngology-Head and Neck Surgery, University of Alexandria, Egypt, between January 2000 and December 2002. Under general anesthesia, each patient underwent laser excision of all visible papillomas, followed by topical application of 1 cc of 0.

Partial laser arytenoidectomy in the management of bilateral vocal fold immobility. A modification based on functional anatomical study of the cricoarytenoid joint.

Objectives: To establish the anatomical relationships of the arytenoid and cricoid cartilages and apply these findings to design an arytenoidectomy based on a sound anatomical basis.

Methods: We prospectively conducted this study between 1996 and 2002 at the Main University Hospital of Alexandria, Egypt. In 50 patients, we endoscopically measured the length of the vocal process and the distance between the vocal process tip and upper border of the cricoid cartilage.
