Abstract
Excessive gingival display (EGD) associated with a hypermobile upper lip (HUL) represents a clinical challenge, often associated with postoperative relapse. This case report describes a modified lip repositioning surgery (LRS), termed the 'Butterfly Technique.' This suturing strategy utilizes a sequential intramuscular pathway to engage the principal elevator muscles, including the orbicularis oris, depressor septi nasi, levator labii superioris alaeque nasi, levator labii superioris, and zygomaticus minor and major muscles, without the need for invasive myotomy. By creating a multipoint containment system, the technique was designed to modulate vertical lip excursion and improve postoperative stability. A 32-year-old woman presenting with approximately 4 mm of gingival exposure during maximum smiling was treated with this protocol, with stable results maintained at the 3-year follow-up. Within the limitations of a single case report, the Butterfly Technique may represent a minimally invasive modification of LRS for the management of EGD associated with HUL. Further controlled clinical studies with larger sample sizes are required to confirm these findings.
