Abstract

BACKGROUND:

This study was designed to comparatively assess laryngeal function and quality of life (QOL) of patients after laser surgery (LS) or radiotherapy (RT) for early glottic cancer.

METHODS:

Sixty-four patients with T1 glottic cancer treated with RT or type II cordectomy underwent both subjective and objective vocal assessments. The LS group was divided into the following: (1) vaporization with defocused mode (laser surgery [LS]-Vap); and (2) excision with focused mode using lower power (LS-Ex).

RESULTS:

Auditory-perceptual evaluation and videostroboscopic images in the LS-Ex group worsened shortly after treatment and time-dependent recovery was quicker than in the LS-Vap group. The LS-Ex group showed equivalent posttherapeutic vocal function with the RT group by acoustics, aerodynamics, and self-assessment questionnaire analysis, whereas the LS-Vap group showed statistically significant worse function.

CONCLUSION:

The multidimensional assessment showed that early glottic cancer could be successfully treated by either RT or LS-Ex with equivalent posttherapeutic laryngeal function and QOL. © 2016 Wiley Periodicals, Inc. Head Neck 38: 1085-1090, 2016.
