OBJECTIVE: The objective of this study was to prospectively evaluate the long-term efficacy of rapid maxillary expansion (RME) in a group of @entity1 with @entity27 ( @entity27 ). MATERIAL AND METHOD: Thirty-one @entity1 diagnosed with @entity27 were involved in the study. These @entity1 had isolated maxillary narrowing and absence of enlarged adenotonsils at baseline. Twenty-three individuals (73% of the initial group) were followed up annually over a mean of 12 years after the completion of orthodontic treatment at a mean age of 8.68 years. Eight @entity1 dropped out over time due to either moving out of the area (n   =   6) or refusal to submit to regular follow-up (n   =   2). Subjects underwent clinical reevaluation over time and repeat polysomnography (PSG) in the late teenage years or in their early 20s. During the follow-up period, eight @entity1 dropped out and 23 individuals (including 10 @entity1 ) underwent a final clinical investigation with PSG (mean age of 20.9 years). The final evaluation also included computerized tomographic (CT) imaging that was compared with pre- and post-initial treatment findings. RESULTS: Yearly clinical evaluations, including orthodontic and otolaryngological examinations and questionnaire scores, were consistently normal over time, and PSG findings remained normal at the 12-year follow-up period. The stability and maintenance of the expansion over time was demonstrated by the maxillary base width and the distance of the pterygoid processes measured using CT imaging. CONCLUSION: A subgroup of @entity27 @entity1 with isolated maxillary narrowing initially and followed up into adulthood present stable, long-term results post RME treatment for pediatric @entity27 .
