Liberação do músculo depressor do septo nasal e sorriso gengival

Abstract

The Septum Depressor Muscle Release (LMDSN) technique was initially used as an aesthetic approach to correct the tip of the nose, however, in this study, it was performed to correct the gingival smile, since this anatomical structure is related to the fall of the nasal tip, elevation and shortening of the upper lip and increased maxillary gingival exposure. For patient selection, some criteria were taken into account, such as having a gummy smile caused by muscle hypermobility, without skeletal involvement. Thus, the primary objective of this study was to report the clinical case of a 45-year-old female patient, diagnosed with gummy smile caused by upper lip hyperreactivity, in which LMDSN surgical procedure was performed. Secondly, the objective was to describe the technique using cadaver, thus enabling a better elucidation of the anatomical structures involved in this approach. The process performed proved to be effective for reducing the gummy smile, resulting in the stretching of the upper lip at rest, an increase in the vermilion thickness of the lip during the smile and elevation of the tip of the nose. recurrences and subsequent complications were observed during a 1 year follow-up.
