A novel measurement system for assessing the nose in patients with cleft lip and palate (CLP)

Abstract

ObjectiveThe presented study shows a new and innovative method to determine nasal asymmetries in a simple way in patients with cleft lip and palate (CLP) in order to plan corrective surgery. Design86 non-syndromic patients with cleft lip and palate were divided into 2 groups: a) patients with unilateral cleft lip and palate b) patients with bilateral cleft lip and palate. Patientsfollow-up of hospital records of 86 patients aged 2–18 years. Main outcomeBased on standardised photos of the nose from 3 different directions, the nose symmetry was assessed. A new digital measurement system was used, which is integrated into proven clinical programmes. These were compared with a control group. In addition, a mirror fog test and a standardised questionnaire were used. ResultThe overall results showed a good symmetry of the nose postoperatively, as well as a high satisfaction of the patients and their parents. Profile and angle measurements showed a better result. ConclusioThe presented measurement system and especially the Cleft Lip Component Symmetry Index (CLCSI) allows an individual and very effective assessment of the symmetry of the nose as well as a control of the growth in patients with CLP. The method is easy to apply in daily practice, even for untrained practitioners.
