Aim: The objective of the current study was to evaluate the soft tissue changes on the lateral cephalometric x-ray associated with the lip repositioning surgery and/or botulinum toxin injections.

Methods: Thirty female patients were included in this study who suffered from gummy smile owing to hypermobility of the upper lip. Lateral cephalometric x-ray was obtained for all patients where soft tissue analysis was done by tracing using software program and the interlabial distance and lip length at rest were verified. Patients were divided at random into 3 groups, group 1 were treated with lip repositioning surgery, group 2 were treated with botulinum toxin injections and group 3 was treated by botox injections followed by lip repositioning surgery after 14 days. Postoperative assessment included recording the changes in the same preoperative measurement.

Results: Post-operative assessment using lateral cephalometric soft tissue showed an increase in the upper lip length with a decrease in the inter-labial distance at rest in the third group.

Conclusion: Lateral cephalometric soft tissue analysis has been proven to provide adequate information about the upper lip changes associated with both procedures.
