Mioplastia nasolabial – relato de caso clínico

Abstract

INTRODUCTION: Within the current aesthetic standards sought and imposed in society, the smile makes up a large part of facial aesthetics, which depends on a careful analysis of the face, always seeking harmony, balance and proportion between smile, lips, eyes, skin, among others. A major responsible for causing this facial aesthetic imbalance is the gummy smile, which can trigger aesthetic dissatisfaction, low self-esteem and even interfere with interpersonal relationships. The gummy smile has different causes that need to be correctly identified in order to choose the best treatment. For some cases, the technique called nasolabial myoplasty has been indicated and performed, both for its practicality and effectiveness, providing a satisfactory result in most patients. OBJECTIVE: To report a clinical case of a patient with gummy smile and drooping nose using the nasolabial myoplasty technique for correction. METHODOLOGY: Nasolabial myoplasty surgery was performed to correct gummy smile due to gingival exposure due to lip hypermobility in a female patient, 29 years old, Caucasian. The technique consisted

of an incision in the mucogingival line, with subsequent tissue retraction in the labial- nasal direction, seeking to detach the medial portion of the nasal septum depressor

muscle and dermocartilaginous ligament. Tissue removal was performed in the area between two imaginary lines drawn on the long axis of teeth 11 and 21. After removal, leaving the bone exposed, surgical cement was introduced, keeping it for seven days in the region in order to avoid reinsertion. muscle. Follow-up was performed for six months after therapy, evaluating maintenance of post-surgery lip position, gummy smile correction and patient satisfaction. RESULTS: After 30 days, there was a lengthening of the upper lip at rest, as well as a significant reduction in its shortening when smiling. Accompanied by this, an elevation of the nasal tip at rest and an increase in the thickness of the labial vermilion were observed during smile. The correction of the high smile line was carried out without compromising the harmony of the lip, maintaining the patient's original lip profile. In addition, a high

degree of patient satisfaction was achieved after surgery and maintenance of long- term results. CONCLUSION: Currently, some surgical techniques are presented to

reduce lip hyperactivity, which can be performed intraorally or extraorally. Among these, nasolabial myoplasty is highly indicated, having as main advantages its extreme simplicity and minimal morbidity, in addition to the expressive results obtained quickly and effectively.
