RESUMO
The presence of lower lip pits in individuals with Van der Woude syndrome (VWS) may cause discomfort due to saliva secretion. Furthermore, one of the main complaints in relation to lip pits is poor aesthetics, which often affects quality of life. The aim of this systematic review was to identify the best technique for the surgical removal of lower lip pits in terms of aesthetic and functional characteristics. A search of the PubMed, Embase, Web of Science, Science Direct, and Scopus databases was performed on December 27, 2016, which retrieved 88 records without duplicates. Among these papers, three ultimately met all eligibility criteria. The three studies included a total of 61 individuals, with follow-up ranging from 6 months to 10 years and sample collection from 10 to 24 years. The findings demonstrated that the outcome of surgical removal of lower lip pits was better with the use of vertical wedge excision, inverted-T lip reduction, Mutaf-Goldstein technique and modified simple excision than with simple excision. Simple excision may result in postoperative complications, such as mucocele and pit recurrence.
