Background: Recently, the use of barbed pharyngoplasty (BP) has become widespread in snoring and obstructive sleep apnoea (OSA) palatal surgery, but there are no studies regarding the short- and long-term complications resulting from these different techniques. This systematic review aimed to report the complications and side effects of different BP techniques.
Methods: An electronic search was performed on PubMed/MEDLINE, Google Scholar, and Ovid databases. The PRISMA statement was followed. Databases were searched from inception through September 2, 2021.
Results: We included 14 prospective clinical studies consisting of 769 patients aged 23 to 81 years. The associated intra-operative complications of BP were as follows: partial thread extrusion (2.9%), self-limited bleeding (2.9%), broken needle (1.0%), and suture rupture (1.0%). Short-term complications were as follows: thread/knot extrusion (12.4%), dysphagia (5.6%), bleeding (1.5%), velopharyngeal insufficiency (1.5%), anterior pharyngoplasty dehiscence (1.2%), tonsillar haemorrhage (1.0%), excessive postnasal discharge (1.0%), barbed suture failure (0.5%), acute infection (0.2%), mucosal granulomas (0.2%), chipped tooth caused by mouth gag displacement (0.2%), and fibrous scar (0.2%). Long-term complications were as follows: foreign body sensation (7.8%), sticky mucus in throat (5.9%), dysphagia (3.6%), rhinolalia (3.1%), throat phlegm (1.1%), nose regurgitation (0.8%), dry throat (0.6%), and throat lump (0.3%).
Conclusion: BP is a safe technique free of significant side effects and major complications. However, in this review, patients undergoing BP were very heterogeneous in terms of characteristics of patients chosen and severity of diseases, surgical technique used (myoresective vs non-myoresective), time of follow-up, and mono level vs multilevel surgery. More studies on a larger scale with long-term follow-up are needed to confirm these promising results.
