Mandibular third molar surgery with primary closure and tube drain

Area of Science:

• Oral and Maxillofacial Surgery
• Surgical Techniques
• Wound Management

Background:

• Impacted third molar removal is a common surgical procedure.
• Postoperative complications such as swelling, pain, and wound breakdown can occur.
• The use of surgical drains following primary wound closure is a debated topic.

Purpose of the Study:

• To compare the efficacy of small surgical tube drains with primary wound closure versus simple primary wound closure alone after impacted third molar removal.
• To evaluate the impact of surgical drains on postoperative complications including pain, swelling, and wound healing.

Main Methods:

• A randomized cross-over study involving 23 patients undergoing impacted third molar removal.
• Comparison between two groups: drain group (small surgical tube drain with primary wound closure) and no drain group (simple primary wound closure).
• Data collected included operation time, mouth opening, pain severity, facial swelling, and incidence of wound breakdown, edema, and bleeding.

Main Results:

• The drain group experienced significantly longer operation times and wider immediate postoperative mouth opening (P > or = 0.01).
• Facial swelling was significantly reduced in the drain group (P > or = 0.01).
• Fewer patients in the drain group experienced wound breakdown, edema, and bleeding compared to the no drain group.

Conclusions:

• The use of small surgical drains with primary wound closure appears to be beneficial in reducing postoperative complications after impacted third molar surgery.
• While operation time and immediate mouth opening may increase, the overall reduction in swelling and wound-related issues suggests a favorable outcome for the drain group.
• Surgical drains may be a valuable adjunct for managing impacted third molar extraction sites.
