Alar Base Surgery

Smiling deformity: This is a condition where the nasal tip droops significantly when the patient smiles and distorts the nose’s appearance, and the distance between the nasal tip and the upper lip decreases. If this deformity includes the appearance of gums while smiling, it is called the gummy smile.

Michel Kane [13] described the use of botulinum toxin by injecting into muscles associated with the dynamic behavior of the NLF. In certain patients, mimetic muscles around the NLF have cutaneous insertions in the fold, making it prominent by their early to mid-thirties. In the early 30s to late 50s, botulinum toxin can thus be used to weaken muscles (such as the LLSAN), thereby improving the NLF. A canine or gummy smile may also be improved in this manner. However, in case of ptosis of the soft tissues, botulinum toxin in the mimetic muscles is of limited use.

A gummy smile (greater than 2 mm of gingival show), in its mild form may be considered cute in the young, but can often be distracting in the adult. The perioral complex consists of interdigitating lip elevators and depressors with the orbicularis muscle, and as such is extremely diverse and confusing. Numerous anatomical variants of gummy smile have been described,33–38 however, the authors have found that for the purposes of injection therapy, three basic types exist, as defined by the intended location of toxin injections: those that target the confluence of the levator labii superioris alaeque nasi (LLSAN) and zygomaticus minor muscles; those that target the orbicularis oris; and those that target both.

Although clinically MH is not a medical problem or a disease, the demand for cosmetic corrections is on the increase, mainly by fair-skinned people and when MH is located on the anterior labial gingiva (2–5).This problem is aggravated in patients with a “gummy smile” or excessive gingival display while smiling (2–7). Gingival depigmentation is a periodontal surgical procedure, whereby the gingival hyperpigmentation is removed or reduced with different treatment methods, such as bur abrasion, scraping with scalpel, partial thickness flap, gingivectomy, cryotherapy, electrosurgery, free gingival autografting, chemical methods, subepithelial connective tissue graft, lasers and combination techniques (1–4). Even though selection of a technique is mainly based on clinical experience and individual preferences, most authors recognize laser ablation as the most effective, pleasant and reliable technique for depigmentation of gingiva (1–4).

This problem was resolved by the introduction of horseshoe osteotomy, which allows for posterior-superior maxillary repositioning with no risk of damaging the descending palatine artery [12]. Although previous reports have described LeFort I osteotomy combined with horseshoe osteotomy as useful for patients with a severe gummy smile, long face and bimaxillary protrusion [9,12–15], modified horseshoe osteotomy for treatment of facial asymmetry caused by maxillary cant has not been reported. We expressed this modified method as unilateral horseshoe osteotomy in this case report.
