Cleft lip re-repair: How does it affect the nasolabial appearance?

Cleft lip re-repair is a procedure frequently endorsed to enhance a compromised nasolabial appearance. However, the actual effect of such revision surgery on the nasolabial appearance has scarcely been studied. Therefore, the aim of this study was to critically review surgical outcomes of patients that underwent surgical re-do of their cleft lip, using well-validated objective and subjective methods and standardised outcome measures.

20 patients with at least 6 months follow-up after cleft lip re-repair were assessed. Standardised pre- and postoperative photographs were analysed. The objective assessment was carried out using the SymNose-software. Furthermore, a subjective evaluation of the nasolabial area was conducted by ten examiners who rated seven parameters using a Likert-scale ranging from 1to5. The objective evaluation showed substantial improvement regarding symmetry values. Significant postoperative decrease in labial asymmetry from 26.42% (±8.13) to 18.77% (±6.28) (p < 0.001) and upper lip asymmetry in relation to the facial midline (26.91% (±8.03) vs. 18.27% (±5.17) (p < 0.001)) was observed. Similar results were corroborated in the subjective analysis. Differences regarding the ratings were detected considering the examiners’ professional background and level of expertise. Cleft re-repair was found to significantly improve upper lip symmetry and lead to a more harmonious nasolabial appearance.
