摘要

Introduction

Accessory innervation from the cervical plexus is attributed as a plausible explanation for inadequate pain control during surgical removal of mandibular impacted third molars. This study assessed the effectiveness of adjuvant superficial cervical plexus block (SCPB) to the conventional inferior alveolar nerve block (IANB) for managing intraoperative pain during mandibular third molar surgery.

Materials and Methods

A double-blind, randomized trial with 64 patients undergoing mandibular third molar surgery was divided into two groups of 32 patients. Group A received IANB alone, while Group B received IANB with SCPB. Intraoperative pain was the primary outcome, measured by visual analogue scale. Pain on the first and fifth post-operative days was a secondary outcome. Paired t-tests analysed the data, with p < 0.05 indicating significance.

Results

Statistical analysis revealed that Group A patients who received only IANB had significantly higher VAS pain scores both during the intraoperative procedure and on the first post-operative day (P < 0.05) compared to Group B who received the adjuvant SCPB injection.

Conclusion

Combining SCPB with IANB effectively reduced intraoperative pain during mandibular impacted tooth removal and improved patient comfort on the first post-operative day. This highlights SCPB's value as an adjuvant for better pain management in mandibular third molar surgery.
