Swallowing evaluation after surgery for obstructive sleep apnea syndrome: uvulopalatopharyngoplasty vs. expansion pharyngoplasty.

Purpose: To evaluate the effect of pharyngeal surgery on swallowing pattern in patients with obstructive sleep apnea syndrome (OSAS), and to compare two surgical techniques: uvulopalatopharyngoplasty (UPPP) and expansion pharyngoplasty (EP), through videofluoroscopy.

Methods: Longitudinal prospective cohort, in a tertiary referral center. 17 adult patients were enrolled this study, divided into two groups: patients who underwent UPPP (n = 10) or EP (n = 7).

Standardization of acoustic measures for normal voice patterns.

Unlabelled: Studies have established that normative data is necessary for acoustic analysis. The aim of the present study is to standardize fundamental frequency measures (fo), jitter, shimmer and harmonic-noise ratio (HNR) for young adults with normal voice.

Method: 20 males and 20 females, between 20 and 45 years, without signs and symptoms of vocal problems; CSL-4300 Kay-Elemetrics; vowels /a/ and /é/.
