Pedunculated polyp removal by means of larynx fiberendoscopic surgery

Abstract

To evaluate the stroboscopic and acoustic results obtained with larynx fiberendoscopic surgery (LFS) to remove pedunculated vocal fold polyps. Prospective study, comparing before and after surgery results. We used a series of 31 patients, with a pedicled vocal fold polyp. To remove the pedunculated polyp, we used LFS. This technique consists of excising vocal fold injuries under local anaesthesia by means of micro tweezers using a canal larynx fiberscope. Subjects were evaluated on three occasions: before surgery, 2 and 4 weeks after surgery. After surgery, improvement obtained in stroboscopy examination was statistically significant (p < 0.001) and 100% of the patients had recovered a mucosal wave. After 4 weeks of surgery, all acoustic parameters reached normality ranges. LFS used for the removal of pedunculated vocal fold polyps produces acoustic and stroboscopic improvements, comparable to those obtained using direct laryngoscopy.
