Influence of different techniques of secondary cleft lip revision surgery on upper lip projection.

Patient dissatisfaction with labial appearance in the adult cleft lip is frequently linked to poor upper lip projection. Other areas of concern include asymmetry and impaired upper lip height. Different surgical techniques are available to address volumetric deficiencies, according to extent and localization. However, data comparing outcomes in these different areas are limited. The main aim of this study was to assess the relative gains in upper lip projection. An evaluation of upper vermilion height and symmetry was also performed. Thirty-seven consecutive patients treated by a single surgeon had their pre- and postoperative results measured using standardized photographs; these were analysed using subjective and objective outcome measures. Seven examiners evaluated anonymized pre- and postoperative side and front views for subjective evaluation. The objective analysis was performed using Adobe Photoshop. Fifteen lip revisions, four Abbe flaps, 12 dermal grafts, and six PermaLip implants were performed. In bilateral cleft lip and palate patients, Abbe flaps showed the most significant improvement in labial projection, followed by PermaLip implants and dermal grafts. In unilateral cleft lip and palate patients, PermaLip implants best addressed impaired lip projection, followed by dermal grafts. Overall, functional lip revisions showed excellent outcomes for upper lip symmetry; however, only minor changes in labial projection were found.
