Hypothesis
Is mandibular anglectomy an effective treatment for improving mouth opening in patients with masticatory muscle tendon-aponeurosis hyperplasia (MMTAH)?
Conclusion
Mandibular anglectomy is effective in maintaining the mouth opening range in patients with MMTAH.
Supporting Evidence
- Patients who underwent mandibular anglectomy showed a significantly greater mouth opening range both preoperatively and postoperatively compared to those who did not undergo the procedure.
- At six months postoperatively, the mean mouth opening range in all patients was 40.1 mm, with those who had mandibular anglectomy achieving 46.8 mm.
Takeaway
This study found that a surgery called mandibular anglectomy helps people open their mouths better if they have a condition that makes it hard to do so.
Methodology
The study retrospectively analyzed 14 patients diagnosed with MMTAH, assessing their mouth opening range before and after surgery.
Limitations
The study was conducted at a single center with a small sample size.
