OBJECTIVE: To evaluate the role of @entity2701 on the genioglossus muscle in the performance of genioglossus advancement on @entity25 @entity1353 in @entity1 undergoing @entity27 ( @entity27 ) surgery. STUDY DESIGN: Prospective study. SETTING: Academic practice. SUBJECTS AND METHODS: Twenty-three subjects underwent genioglossus advancement with uvulopalatopharyngoplasty for @entity27 . Subjects underwent pre- and postoperative polysomnography, cephalometry, and subjective assessment questionnaires. Eighteen subjects completed the study. The @entity2701 force of the mandible and the bicortical width of the genial tubercle were measured and surgical response determined. RESULTS: Improvement in @entity27 index (AHI) was seen in 15 of 18 subjects (83.3%). Eleven subjects were classified as responders and 7 as nonresponders (61.1% success), with responders exhibiting a statistically significant reduction in mean delta AHI as compared with nonresponders: 28.3    26.2 versus 2.0    22.0 events per hour (95% confidence interval, 1.8-50.8; P = .037). The Epworth Sleepiness Scale improved from 13.2    4.5 to 7.6    3.4 (P = .002). There was no significant difference in body mass index, neck circumference, overall @entity2701 , or mandibular width between responders and nonresponders. However, there was a significant difference in the @entity2701 :width ratio between responders (53.9    6.38 g/mm) and nonresponders (65.4    11.2 g/mm; 95% confidence interval, 0.92-22.1; P = .036). CONCLUSION: This article describes a novel approach to determine the force applied to the genioglossus during advancement and its correlation to postoperative outcomes. The @entity2701 :width ratio may be an indicator for postoperative success and delta AHI improvement in @entity27 @entity1 .
