Abstract Conclusion: Selected patients might have beneﬁted from genioglossus advancement (GA), even it was applied solely. GA provided signiﬁcant reduction on the apnea hypopnea index (AHI), with a 53% surgical success. Objectives: The aim of this study was to evaluate the impact of GA on AHI of patients with obstructive sleep apnea (OSA). Method: From January 2008 to April 2014 patients who underwent a genioglossus advancement procedure alone were included into the study and records of these cases were analyzed retrospectively. Pre-operative and post-operative values of body mass index (BMI), Epworth Sleepiness Scale (ESS), nocturnal polysomnographic data including AHI, mean, and minimum oxygen saturation were compared. Results: There were 16 males and one female patient with the mean age of 46 years. The AHI showed a signiﬁcant reduction from 27.5 ± 8 pre-operatively to 17.3 ± 12.6 post-operatively. The pre-operative and post-operative mean O2 saturation value improved from 92.1 ± 2.4% to 93.4 ± 1.7%. Pre-operative ESS scores decreased signiﬁcantly from 7.7 ± 1.6 to 4.8 ± 1.9. There were no signiﬁcant difference between pre- and post-operative values of BMI and minimum O2 saturation. The success rate was found to be 53%, which was based on success criteria as an AHI of 0.05) between pre-operative and post-operative minimum O2 saturation values. The
pre-operative and post-operative values of ESS, AHI, mean O2 saturation, and minimum O2 saturation are summarized in Table I. None of the patients had major complications of the GA procedure, including mandible fractures, mental nerve injury, and loss of tooth after root injury. However, 16 of the 17 patients (94%) suffered from transient numbness, lasting a mean of 2.8 ± 1 weeks (range = 1–5 weeks), of the lower lip and mental region. Surgical success was deﬁned as AHI
