Indirect laryngeal surgery of vocal fold polyps: a dying or evolving art?

ABSTRACT

Objective: Vocal fold polyps (VFPs) are the most common benign laryngeal lesions that require surgery and are routinely managed by microlaryngoscopy (MLS) under general anaesthesia. Prior to introduction of MLS, VFPs were removed using indirect laryngoscopic surgery (ILS) in local anaesthesia, a procedure that required substantial surgical skill to operate with an unmagnified mirror view of the larynx. With the adoption of wireless endoscopy equipment and personal computers, we tried to simplify this technique so that it can be easily performed in the office. This study aimed to assess the effectiveness of ILS by comparing voice outcomes with MLS. Materials and methods: ILS and MLS were performed in six patients each. Treatment outcomes were measured using a voice self-assessment and objective acoustic analysis. The total cost of both procedures was calculated. Results: Both techniques allowed successful removal of VFPs in all patients, without significant intergroup differences in voice outcomes. The cost of ILS was significantly lower. Conclusions: Despite the pilot nature of the study and the small sample size, our data indicate the potential value of this technique which, considering its simplicity and economic value could be used as an alternative to MLS in carefully selected patients.
