title: Sole effect of genioglossus advancement on apnea hypopnea index of patients with obstructive sleep apnea.
abstract: CONCLUSIONS
  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.
  
  
  OBJECTIVE
  The aim of this study was to evaluate the impact of GA on AHI of patients with obstructive sleep apnea (OSA).
  
  
  METHODS
  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 <20 with at least 50% reduction.
