Analysis of the complications in patients undergoing orthognathic surgery by piezosurgery®: A 13 years retrospective study

Orthognathic surgery is a branch of maxillo-facial surgery increasingly in demand, which deals with the correction of skeletal deformities. The aim of the present study is to identify the most common post-operative complications following orthognathic bimaxillary surgery performed by means of Piezosurgery® . Furthermore, through an examination of the available scientific literature, we wanted to establish whether the frequency of postoperative complications were consistent with those already reported. A retrospective study on 58 patients who underwent orthognathic surgery with a bilateral sagittal osteotomy (BSSO) of the mandibular bone branch, maxillary surgery with Le Fort I mono-segmented or multi-segmented approach, and genioplasty technique using Piezo-surgery® . The complications taken into consideration were disorders of the temporomandibular joint (TMJ), paraesthesia and hypoesthesia, asymmetries, nose enlargement, nasal septum devia-tion, nasal obstruction, dental discolorations, pulpal necrosis, occlusion and masticatory efficiency, gingival recession, periodontal problems, dysgeusia, nausea and vomiting, weeping alterations, hearing problems, delayed healing, superinfection, removal of synthesis means, reoperation, cica-tricial outcome, and bilateral pneumothorax. It has been highlighted that a number and type of postoperative complications matched those reported by the most recent literature reviews. Tem-poromandibular disorders and paraesthesia were the most common ones. The only complication rate that differed from the literature was nerve damage, which was significantly lower. Post-surgi-cal complications depend on the used surgical techniques, clinical work, and treatment methods. The use of piezoelectric devices in orthognathic surgery operations provides an innovative, safe, and effective technique compared to traditional methods.
