Comparison of treatment outcomes of transnasal vocal fold polypectomy versus microlaryngoscopic surgery.
Laryngoscope. 2015 May; 125(5):1155-60.L

Abstract

OBJECTIVES/HYPOTHESIS

Office-based procedures have been proposed for the treatment of vocal polyps, including indirect laryngoscopic surgery and angiolytic laser photocoagulation. Our previous report documented good treatment outcomes by combining the two aforementioned procedures. This study was intended to further compare the treatment outcomes of office transnasal vocal fold polypectomy (VFP) with those of microlaryngoscopic surgery (MLS).

STUDY DESIGN

A matched cohort study.

METHODS

This study retrospectively enrolled 50 age-, gender-, and size-matched patients with vocal polyps treated by VFP or MLS at a tertiary teaching hospital from January 2012 to October 2013. Treatment outcomes were evaluated before, 2 weeks, and 6 weeks after the procedures via perceptual rating of voice quality, acoustic measurement of the speech signal, 10-item voice-handicap index, maximal phonation time, subjective rating of voice quality, and videolaryngostroboscopic evaluation.

RESULTS

Both VFP and MLS resulted in significant clinical improvements 2 and 6 weeks postoperatively. Study results exhibited similar objective outcomes between VFP and MLS, whereas patients who received VFP reported higher subjective voice quality than those receiving MLS 2 weeks postoperatively. Six weeks after the procedures, the objective and subjective treatment outcomes were not significantly different between the two treatment groups.

CONCLUSION

This study shows that transnasal VFP may be used as an effective alternative treatment for small vocal polyps. Patients who received office VFP experienced rapid symptomatic relief with a higher degree of subjective effectiveness than MLS 2 weeks postoperatively, whereas the overall treatment outcomes showed a comparable level of effectiveness for both modalities.
