Summary
Surgically assisted rapid maxillary expansion is effective for correcting transverse maxillary deficiencies. This study found no significant differences between techniques with or without pterygoid plate detachment.
Area of Science:
- Orthodontics
- Maxillofacial Surgery
- Dental Research
Background:
- Transverse maxillary deficiencies are common in skeletally mature patients.
- Surgically assisted rapid maxillary expansion (SARME) is an established treatment.
- Pterygoid plate detachment is a variable in SARME techniques.
Purpose of the Study:
- To compare the efficacy of SARME with and without pterygoid plate detachment.
- To evaluate skeletal changes following these two SARME techniques.
Main Methods:
- A randomized cohort study of 10 adult patients (18-40 years) with transverse maxillary deficiency (>4 mm).
- Two groups (n=5 each): SARME with pterygoid plate detachment vs. without.
- Measurements included dental casts, cephalometric radiographs, and occlusal radiographs pre- and post-operatively (30 days).
Main Results:
- No statistically significant differences were observed between the pre- and post-operative measurements for either group.
- Both SARME techniques resulted in similar skeletal outcomes in the short term.
Conclusions:
- Current evidence suggests pterygoid plate detachment may not significantly alter SARME outcomes.
- Limited randomized controlled trials exist; larger sample sizes are needed for definitive conclusions.
