This study aims to evaluate the effectiveness of both injection botulinum toxin type A (Botox) and surgical lip reposition in the correction of the gummy smile due to hyperactive upper lip based on the resulting smile and patients' satisfaction. This is done to device a less damaging (to tissues) and more stable alternative in giving results with statistical importance and aesthetically satisfying results. The method was tested on 24 patients: 12 received the BTX-A injection and the remaining 12 underwent surgical lip reposition. The patients rated their satisfaction according to their gingival display that was defined as the difference between the lower m�¬�¬argin of the upper lip and the superior margin of the right incisor. These patients were followed up at 2 weeks, 2 months and 6 months, post-injection and post-surgery with changes documented by photographs. Both groups answered a questionnaire addressing the overall appe�¬�¬�¬arance and they were asked to rate the improvement of their smile based on a 5-point aesthetic scale. BTX-A injection exhibits better results than those of surgery and had given safer and more satisfactory results than lip reposition. The patients rated the effects of BTX-A as highly favorable, if we take into consideration that BTX-A was temporarily effective but the surgical procedure (lip reposition) is 80% recurrent surgery as the lip reverted back to its original position with almost complete relapse after 6 months, containing all the dangers affiliated with the surgical procedures.
