Abstract
To evaluate the efficacy of eight different surgical treatments based on maxillomandibular advancement (MMA), which has emerged in recent years, for adult obstructive sleep apnoea (OSA) patients. The literature was searched from January 2010 to May 2020 for studies of adult OSA patients with different types of MMA procedures to perform a network meta-analysis. The outcomes were changes in the apnoea-hypopnoea index (AHI), the lowest pulse oxygen saturation (SpO2 min) and the Epworth Sleepiness Scale (ESS). Treatment hierarchy was summarized according to the rank charts. Eight studies were included and encompassed a total of 227 adult patients diagnosed with OSA. Among them, 225 patients underwent combined surgery or simple MMA surgery, including modified maxillomandibular advancement (MMMA),counterclockwise maxillomandibular advancement (CMMA), drug-induced sleep endoscopy and maxillomandibular advancement (MMA + DISE), transoral robotic surgery and maxillomandibular advancement (MMA + TORS), uvulopalatopharyngoplasty (UPPP), maxillomandibular advancement and uvulopalatopharyngoplasty (MMA + UPPP), uvulopalatopharyngoplasty with uvula preservation and maxillomandibular advancement (MMA + HUPPP); MMA consisting of Le Fort I osteotomy and bilateral inverted-L osteotomy (ILOs), genioplasty and iliac bone grafting; and MMA consisting of Le Fort I osteotomy, bilateral sagittal split ramus osteotomies and genioplasty. The results showed that the most effective surgical treatment is MMA + HUPPP [-56.79 (WMD); 95% confidence interval (CI): -113.02 to -3.33] (P < 0.00001), which was far superior to other approaches. MMA combined with HUPPP had the highest efficacy. The MMA consisted of Le Fort I osteotomy, bilateral sagittal split ramus osteotomies and genioplasty; CMMA and MMA + TORS are likely also great choices.
