Abstract Nasal polyps are associated with hyponasality. The effect of functional endoscopic sinus surgery (FESS) on voice quality has not been adequately investigated; therefore, this study developed objective and subjective measurements to compare nasal polyp patients pre- and postsurgery. An observational prospective study was conducted at Srinagarind Hospital, Khon Kaen University, Thailand. Bilateral nasal polyposis patients who underwent FESS between August 1, 2015 and August 1, 2017, were recruited. All participants were assessed for nasal polyp grade, nasometry, acoustic parameters, acoustic perception, and patient satisfaction before surgery and at the 1-, 3- and 6-month follow-ups. Forty-six patients, 29 males and 17 females (mean age 48.2 years ± 16.2 years), were enrolled. Mean nasometry scores were significantly improved at 1, 3 and 6 months after surgery (p 0.05). Overall acoustic perception, assessed with a set of words and sentences, showed significant improvement in hyponasality voice after surgery (p 0.05). Patient satisfaction with voice changes after surgery was high, with significantly increased mean scores between the 1- and 6-month follow-ups (p
