Abstract

Tsunoda K, Soda Y, Tojima H, Shinogami M, Ohta Y, Nibu K, Tayama N, Niimi S, Hirose H. Stroboscopic observation of the larynx after radiation in patients with T1 glottic carcinoma. Acta Otolaryngol (Stockh) 1997; Suppl 527: 165-166.

We studied laryngeal video stroboscopy (LVS) system for evaluation of patients with glottic carcinoma (T1N0M0) before and after radiotherapy. There were 10 patients with T1 glottic squamous cell carcinoma (9 men and 1 woman) who received radiotherapy at the Hitachi General Hospital. We performed LVS before and after radiotherapy. The presence or absence of mucosal waves (MW) was particularly noted. No MW were present before radiotherapy but at 1-6 months after, MW gradually appeared. One year after radiotherapy all patients showed MW on LVS. In patients with glottic carcinoma MW recovered after radiation therapy. LVS may be useful for the clinical follow-up of post-radiation patients for early detection of recurrence of glottic carcinoma.
