A Modified Approach in Lip Repositioning Surgery: A Prospective Study in a Twin Population with a 3-Year Follow-up
The International Journal of Periodontics & Restorative Dentistry
|November 24, 2021
Summary
A modified lip repositioning technique using periosteal sutures demonstrated stable, long-term clinical outcomes and improved patient satisfaction for maxillary lip hypermobility up to three years post-surgery.
Area of Science:
- Oral and Maxillofacial Surgery
- Plastic Surgery
- Orthodontics
Background:
- Maxillary lip hypermobility, often presenting as excessive gingival display, can impact aesthetics and patient confidence.
- Existing surgical techniques for lip repositioning aim to correct this but may lack long-term stability.
- Twin studies offer a unique model to control for genetic factors in evaluating treatment efficacy.
Purpose of the Study:
- To evaluate the long-term clinical and patient satisfaction outcomes of a modified lip repositioning technique incorporating periosteal sutures.
- To compare the efficacy and stability of the modified technique against the original LipStaT technique in a twin population.
Main Methods:
- A randomized controlled trial was conducted with 12 participants (twin pairs) diagnosed with maxillary lip hypermobility.
- Participants were assigned to either the control group (original LipStaT) or the test group (modified LipStaT with periosteal sutures).
- Clinical measurements (lip width, vertical translation, gingival display) and patient satisfaction surveys were collected for up to 3 years post-operation.
Main Results:
- Both techniques showed significant reductions in vertical lip translation and gingival display from baseline.
- The modified technique with periosteal sutures demonstrated more stable outcomes at the 3-year follow-up compared to the original technique.
- Participants in the test group reported higher satisfaction scores at the 3-year mark.
Conclusions:
- The modified lip repositioning technique utilizing periosteal sutures provides stable, long-term correction of maxillary lip hypermobility.
- This enhanced technique improves patient satisfaction and offers a more predictable outcome compared to the original method.
- Periosteal sutures are a valuable addition to lip repositioning surgery for achieving sustained aesthetic and functional results.
