Summary
Piezoelectric surgery offers reduced pain and swelling for mandibular cyst enucleation compared to traditional rotary methods. This innovative technique demonstrates superior postoperative outcomes and patient comfort.
Area of Science:
- Oral and Maxillofacial Surgery
- Minimally Invasive Surgical Techniques
Background:
- Mandibular cysts pose surgical challenges, often requiring enucleation.
- Conventional rotary instrumentation carries risks of nerve damage and prolonged recovery.
Purpose of the Study:
- To compare piezoelectric surgery with conventional rotary surgery for mandibular cyst enucleation.
- To evaluate the suitability and postoperative outcomes of both surgical methods.
Main Methods:
- Eighty patients with cystic mandibular lesions were randomly assigned to either piezoelectric (piezo-group) or conventional rotary (rotatory-group) surgery.
- Postoperative swelling was assessed at 24, 48, 72 hours, and 1 week.
- Patient-reported pain was recorded daily for 7 days using a Visual Analog Scale (VAS).
Main Results:
- The piezoelectric group experienced significantly lower VAS pain scores and reduced swelling.
- Recovery time was shorter in the piezoelectric group.
- No mandibular nerve lesions were observed with piezosurgery, unlike the 8% incidence of hypesthesia in the rotary group.
Conclusions:
- Piezosurgery is an effective alternative for mandibular cyst enucleation compared to traditional burs.
- This technique leads to significantly less postsurgical pain and swelling.
- Piezoelectric surgery enhances patient recovery and minimizes nerve injury risk.
