Kim JW, et al. - The authors evaluated the related factors affecting the success rate of limited palatal muscle resection (LPMR) and inspected if drug-induced sleep endoscopy (DISE) could speculate the therapeutic response to LPMR in patients with obstructive sleep apnea (OSA). For determining the success in OSA patients undergoing LPMR, DISE was discovered to be the only predictive method. Findings also revealed that patients with anteroposterior or concentric total obstruction in the velopharynx could serve as suitable candidates for LPMR.
