Purpose: To compare the complication rates arising from surgical removal of lower third molars (L3M) under general anaesthesia (GA) versus local anaesthesia (LA) in the Oral and Maxillofacial Surgery (OMFS) Department, Hospital Sultanah Nora Ismail (HSNI), Batu Pahat, Johor, Malaysia. Materials and methods: This is a retrospective clinical audit of patients who underwent L3M removal under LA or GA from 1/1/2013 to 31/3/2018, with recorded complications such as surgical site infection (SSI), wound breakdown, severe pain, trismus, retained tooth structure, nerve injury and dry socket evaluated at different time intervals. Results: A total of 313 patients with 375 L3M were included in this study (male: 160, 51.1%;female: 153, 48.9%) with an age range of 18 to 40 years (mean = 27.43 years). 79 L3M were removed under GA (34.2% were classified as mild;65.8% were moderate), whereas 296 L3M were removed under LA, (31.4% were mild impaction, 63.9% moderate and 4.7% severe. Preoperative antibiotics were given before all L3M removal under GA, while only 23 out of 296 L3M removal under LA had antibiotics. 15.2% of L3M removal under GA and 16.6% of those done under LA were associated with complications. Generally, patient with GA had lesser complications;however only SSI outcome was significant (p = 0.034). Conclusion: L3M removal under LA may have a higher risk of SSI when compared to GA. This raises the possibility that a single prophylactic antibiotic dose may prevent SSI in LA procedures.
