All the patients were assessed for pain, trismus and swelling using the visual analog scale, and the data were collected and analyzed with the paired t test after 2 and 7 days. Results: The swelling and pain in group I was greater than that in group II, with a statistically significant difference (P < 0.005). The trismus in group I was greater than that in group II, with a statistically significant difference after 7 days (P=0.03). Conclusion: Our results have shown that the patients in the secondary closure group experienced a significantly lesser amount of pain,trismus and swelling postoperatively compared the primary closure group.
