Patient experience and satisfaction of surgically assisted rapid maxillary expansion and mandibular midline distraction

Little is known regarding patient experience and satisfaction with surgically assisted rapid maxillary expansion (SARME) and mandibular midline distraction (MMD). This study therefore aimed to assess patient experience and satisfaction with these techniques in two different groups. The first group answered the post-surgical patient satisfaction questionnaire on a 7-point Likert scale during a long-term follow-up recall. The second group answered a visual analogue scale questionnaire (range: 0–10) with different questions regarding experience and satisfaction, at different time points during the first year of treatment. In both groups, 17 patients were included. Regarding the post-surgical patient satisfaction questionnaire, a mean satisfaction rate of 6.4 (range: 4–7) was reported, with a mean follow-up of 6.5 years post-operatively. In the visual analogue scale group, the mean satisfaction rate was 8.0 and did not significantly differ from the expectations pre-operative (P = 0.96). Both procedures showed relatively low pain scores, although a significant higher score was observed in MMD post-operatively (P = 0.00051). Regarding hindrance, the scores were moderate; the bone-borne distractor in the mandible gained higher scores than the tooth-borne distractor in the mandible. In conclusion, both SARME and MMD gain high satisfaction rates.
