The classification of the complications aimed to assess the difficulty of their treatment as well as estimate its real cost. Methods: The retrospective study covered 185 patients who underwent surgery for a skeletal deformity in the form of maxillary constriction or in which maxillary constriction was one of its components treated by a team of maxillofacial surgeons at one center (97 females and 88 males, aged 15 to 47 years, mean age 26.1 years). Complications were divided into two groups: early complications (up to 3 weeks after surgery) and late complications (&gt;3 weeks after surgery). In relation to the occurrence of complications, we analyzed the demographic characteristics of the group, type of skeletal deformity (class I, II, III), presence of open bite and asymmetry, surgical technique, type and size of appliance used for maxillary expansion, as well as the duration of surgery. Results: In the study group, complications were found in 18 patients (9.73%). Early complications were found in nine patients, while late complications were also found in nine patients. Early complications include no possibility of distraction, palatal mucosa necrosis, perforation of the maxillary alveolar process caused by the distractor and asymmetric distraction. Late complications include maxillary incisor root resorption, no bone formation in the distraction gap, and maxillary incisor necrosis. None of the patients required prolonged hospitalization and only one required reoperation. Conclusions: Complications were found in 18 patients (9.73%). All challenges were classified as minor difficulties since they did not suppress the final outcome of the treatment of skeletal malocclusion. However, the complications that did occur required additional corrective measures. Surgically assisted rapid maxillary expansion, when performed properly and in correlation with the correct orthodontic treatment protocol, is an effective and predictable technique for treating maxillary constriction.<\/jats:p>","DOI":"10.3390\/jcm13072053","type":"journal-article","created":{"date-parts":[[2024,4,2]],"date-time":"2024-04-02T10:58:31Z","timestamp":1712055511000},"page":"2053","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Complications of Surgically Assisted Rapid Maxillary\/Palatal Expansion (SARME\/SARPE)\u2014A Retrospective Analysis of 185 Cases Treated at a Single Center"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9375-0369","authenticated-orcid":false,"given":"Rafa\u0142","family":"Nowak","sequence":"first","affiliation":[{"name":"Department of Otolaryngology and Maxillofacial Surgery, Institute of Medical Science, University of Zielona G\u00f3ra, 65-046 Zielona G\u00f3ra, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Szymon","family":"Przywitowski","sequence":"additional","affiliation":[{"name":"Face Surgery and Aesthetic Center, Pl.
