The time from the start of numbness to when the subject first requested a dose of oral analgesic was taken as duration of analgesia. Patients were instructed to rate the extent of their pain at 3, 6, 9, and 12 h on the day of surgery (D1), on the first day after surgery (D2) and second day after surgery (D3) using the same VCS Post-operative analgesic consumption was based on the number of tablets used on a daily basis; on the day of surgery (D1), first day after surgery (D2) and second day after surgery (D3) .
Post operatively patients will be given a treatment regimen of antibiotics and analgesics. They should be instructed not to take any analgesics until the lip and tongue were no longer numb All patients were contacted by telephone the day after surgery and encouraged to complete their questionnaires.
