Abstract

BACKGROUND:

A systematic review of the use of stroboscopy as a treatment outcome measure of vocal fold function in patients treated for laryngeal cancer is presented.

METHODS:

Computerized literature searches were performed. Eligible articles were admitted when stroboscopy was used to measure vocal fold function before and after treatment in patients with laryngeal cancer. Data extracted included: tumor stage and location, treatment modality, stroboscopy parameters, parameter scale, number of raters, rater reliability, methodology, and level of evidence.

RESULTS:

Of 520 articles retrieved, 11 studies met inclusion criteria. A total of twenty-four parameters were reported. Rating scales and rater reliability varied.

DISCUSSION:

Major methodological differences exist in studies using stroboscopic findings as voice outcome measures in patients' post-cancer treatment. These differences lead to equivocal findings when assessing the utility of stroboscopy as an outcome measure. Standardized, reliable scoring and reporting systems for laryngeal stroboscopic examinations are needed.
