这是一位极度嗜睡的患者，他的Epworth Sleepiness Scale(爱普沃斯嗜睡量表)得分17，如果此项得分超过10以上，就已算达到需医疗介入的嗜睡程度。
他自己从医院带来的睡眠报告显示，AHI高达64.5(AHI>30属重度睡眠呼吸中止)，最低血氧来到60%。
针对下颚后缩且重度呼吸睡眠中止的患者，正颚手术(Maxillo-Mandibular Advancement, MMA)应该列为优先的治疗选项之一，更何况这位患者完全无法接受长期须配戴阳压呼吸器。
由手术后的电脑断层可以看出，透过上下颚骨的重组，狭窄且阻塞的呼吸道已得到良好的拓宽与支撑，同时，脸型、下巴线条、牙齿角度与咬合状态也受惠于正颚手术。
最重要的，术后的睡眠报告显示，AHI已降低到4.3，已达到与正常人无异的标准，最低血氧也升高到83%，主观感受上，除了大大降低打呼之外，他感觉到白天有精神许多而不会嗜睡。
This is a patient suffering from severe hypersomnia(excessive sleepiness), with an Epworth Sleepiness Scale score of 17.
A score exceeding 10 indicates a level of hypersomnia requiring medical intervention.
The sleep report brought by the patient shows an AHI (Apnea-Hypopnea Index) of 64.5 (AHI > 30 is considered severe obstructive sleep apnea), and the lowest blood oxygen level reached 60%.
For patients with mandibular retrusion and severe obstructive sleep apnea, Maxillo-Mandibular Advancement (MMA) surgery should be prioritized as a treatment option, especially since this patient is completely unable to accept long-term use of CPAP (Continuous Positive Airway Pressure).
Post-operative CT scans reveal that through the reconstruction of the maxilla and mandible, the narrowed and obstructed airway has been effectively widened and supported.
Additionally, the patient's facial contour, jawline, tooth angle, and occlusion have also benefited from MMA surgery.
Most importantly, the post-operative sleep report indicates that the AHI has decreased to 4.3, meeting the standard of normal individuals, and the lowest blood oxygen level has increased to 83%.
Subjectively, the patient feels significant improvement, with reduced snoring and greater energy during the day.
