The typical clinical image involves bilateral mucosal pads separated by a central groove that appear superimposed over the maxillary incisors. The deformity is rather noticeable and esthetically disturbing. Most cases of double lip are congenital, but syndromic appearance of double lip has been described. Surgical reduction of the tissue surplus is the treatment method of choice. The literature suggests excision of excess mucosa and the underlying tissues to correct double upper lip. This report discusses the advantages and pitfalls of resective techniques and suggests a novel, mucosa-sparing, transvestibular approach to correct double upper lip.
