Craniomaxillofacial deformities/cosmetic surgeryComplications Following Surgically Assisted Rapid Palatal Expansion: A Retrospective Cohort Study
Section snippets
Study Design and Sample
The investigators designed and implemented a retrospective review of all patients who underwent SARPE at Kaiser Permanente Oakland Medical Center (Oakland, CA) from January 2004 through December 2008. This study was approved by the Kaiser Foundation Research Institute's institutional review board.
Subjects eligible for study inclusion were consecutive patients who underwent SARPE by 1 of 6 surgeons at the Kaiser Permanente Oakland Medical Center, with or without resident assistance, who had at
Results
One hundred thirty-one patients who underwent SARPE during the study period were identified and 11 were excluded. The study cohort consisted of 120 patients with a median age of 29.5 years (interquartile range, 22.0 to 39.0 yrs) and slightly more than half (51.7%) were women. The median follow-up was 5.6 months (interquartile range, 1.0 to 19.25 mo; Table 1). Relevant comorbidities included diabetes (n = 2), the human immunodeficiency virus (n = 1), and current smoking (n = 13). The vast
Discussion
Of 120 patients who underwent SARPE, 41 developed complications. Overall, most complications were minor and resolved with local measures; however, 15% (n = 18) required additional unanticipated treatment. Asymmetric or inadequate expansion, the most frequent surgical complication, was found in 13.3% (16/120) of the study cohort. Dental and/or periodontal problems, including central incisor discoloration, gingival recession, and periodontal bone loss, occurred in 15% of the cohort. Two patients

Dental complications are usually observed weeks or months after the SARME and mostly concern premolars and molars as these teeth anchor the device [8]. It is important to evaluate the periodontal condition of the anchor teeth to prevent complications.
