“…Over the years, the program has been under constant development in order to improve the accuracy of “measuring” the aesthetic outcome after cleft surgery. As visible scarring plays a role in facial aesthetics, SymNose was further developed to enable the calculation of a subjective scar area between the central half of the upper lip and the lowest outline of the nose (Pigott and Pigott, 2016). Another topic of interest has been variations in lip volume per child.…”

Objective: To provide a normal comparison group against which to judge symmetry results after cleft surgery and to introduce the thin lip correction (TLC) feature in SymNose. A lip–aspect ratio algorithm has been added to the latest version of SymNose to compensate for the higher degree of overlap in thicker lips when compared to thin lips. Design: Retrospective analysis of symmetry in healthy participants, using the computer-based program SymNose on both anteroposterior (AP) and base view images. Photographs of 91 noncleft children were traced twice by 3 independent investigators experienced with SymNose. Participants: Five-year-old healthy participants from a local state school in Tavistock (West Devon, United Kingdom). Main Outcome Measure: Asymmetry expressed as the perimeter mismatch percentage for nose and lip features on AP view images and for nose features on base view images. Results: The perimeter mismatch reference range for the nose (AP view) was 2.65% to 30.91%, for the lip 2.13% to 15.44%, for the nose (base view) 1.69% to 14.84%, for the nostrils 4.68% to 26.6%, and for the width–height ratio 1.15% to 1.80%. The perimeter mismatch percentage for the lip without TLC was significantly higher compared to the perimeter mismatch percentage with TLC ( P < .001). Conclusion: This article provides a noncleft reference range for all perimeters drawn from SymNose against which to compare results after cleft surgery at 5 years of age. Furthermore, it shows the importance of correcting for variance in lip volume per child.
