Ultrasonography in the Evaluation of Midpalatal Suture in Surgically Assisted Rapid Maxillary Expansion
Özet
Surgically assisted rapid maxillary expansion (SARME), which combines orthodontics and surgery, is a well-established therapy for transverse maxillary hypoplasia in adults after sutural closure or completion of skeletal maturation. X-rays are usually the preferred monitoring technique for this treatment. Recently, ultrasound scanning has been used successfully in the follow-up of patients undergoing distraction osteogenesis. In this study, ultrasonography (US) was used in the evaluation of bone callus formation in the midpalatal suture in 3 patients undergoing SARME. For each patient, US was performed immediately after active expansion, at 2 and 4 months of the expansion period, at the removal of the expander 6 months later, and at 2 months after expander removal. The results indicated that US might be a useful and accurate method to assess bone fill in the midpalatal suture in patients undergoing SARME. However, further studies are necessary to clarify the US scores in a larger patient group undergoing SARME.
