Summary
The triangular transposition flap (TTF) likely reduces wound dehiscence after lower third molar surgery compared to the envelope flap. This can improve healing and decrease postoperative complications for impacted wisdom teeth removal.
Area of Science:
- Oral and Maxillofacial Surgery
- Dental Research
Background:
- Wound dehiscence post-lower third molar surgery prolongs recovery and can cause persistent pain.
- Managing complications like wound dehiscence is crucial for optimal patient outcomes.
Purpose of the Study:
- To compare the incidence of wound dehiscence between two soft tissue flap designs.
- Evaluate flap designs for removing mesioangular class IB mandibular impactions.
Main Methods:
- A split-mouth technique compared envelope flaps and triangular transposition flaps (TTF).
- Patients with mesioangular class IB impacted lower third molars were included.
- Outcomes assessed included wound dehiscence, infection, and dry socket formation.
Main Results:
- No infections were reported; dry sockets occurred in 3 (envelope) and 4 (TTF) cases.
- Wound dehiscence was observed in 43% of envelope flap cases versus 19% for TTF.
- Large dehiscences (>5mm) were more frequent with envelope flaps (67% vs 65% for TTF), and extra appointments were higher for the envelope group (10% vs 4.1%).
Conclusions:
- The triangular transposition flap (TTF) appears more effective in preventing postoperative wound dehiscence than the envelope flap.
- TTF may lead to better wound healing and fewer complications after lower third molar surgery.
