Introduction and Objectives: Buccal mucosal graft (BMG) is frequently used for the reconstruction of urethral strictures with acceptable donor-site morbidity after graft harvest. There are only a few prospectively designed studies with a small number of patients reporting oral complications, particularly the mouth opening in the long terms. We did an objective assessment of mouth opening before and after 6 months of BMG urethroplasty as well as pain scores. Materials and Methods: Fifty-eight patients who underwent BMG urethroplasty were included in the study between May 2013 and December 2014. Preoperative mouth opening (reference point between two incisors with the highest of three readings taken as final) was measured using a Vernier caliper. Harvest site was left open to heal by secondary intentions. Postoperatively, mouth opening and pain scores using self-administered (Visual Analog Scale [VAS]) assessed on day 1 and day 3, and follow-up at 1 week, 1 month, and 6 months. Data were analyzed as mean (standard deviation [SD]), proportion, and median (inter-quartile range [IQR]) with two-tailedP < 0.05 as statistically significant. Results: The mean age was 39.6 years. The graft was harvested from a single cheek in 50% of patients. In remaining, it was taken from both cheeks, both cheeks with lip, and both cheeks with the tongue in 29.31%, 17.24%, and 3.5%, of patients, respectively. Preoperative mouth opening (5.13 cm [0.08]) was statistically significantly more than mouth opening on day 1 (4.34 cm [0.09]), day 3 (4.48 [0.09]), and day 7 (4.69 cm [0.09]). Mean difference became insignificant at the interval of 1 month (4.91 cm [0.09]) with 6 months' values showing marginal improvement over preoperative values (5.14 cm [0.07]). Pain was tolerable and patients reported low median VAS 2 (2–4) on day 1 and day 3 each. Reported median VAS became 0 (0–0) on day 7. Conclusion: Mouth opening restriction after BMG urethroplasty is a definite entity in the initial postoperative period, which becomes nonsignificant by 6 months. The pain has no effect on mouth opening.
