Abstract:
OBJECTIVE:To investigate the difference of phonation patterns by dividing patients with vocal fold polyps and vocal nodules into two groups according to muscle tension patterns (MTP).
METHOD:Fifty-six patients with vocal fold polyps and vocal nodules were divided into two groups according to phonation with MTP or not by video strobolaryngoscopy.
RESULT:MTP could be found in 85% patients with vocal nodules and in 55.56% patients with vocal fold polyps. Significant difference was found in patients with/without MTP, and difference was also found in every type of MTP.
CONCLUSION:MTP lies in most patients with vocal nodules while only part of patients with vocal fold polyps, which indicated that vocal fold polyps and vocal nodules may demonstrate different phona
