ABSTRACT
BACKGROUND:
Anthropometric analysis of the face has been performed with direct facial measurement and photogrammetry. Both methods have disadvantages. The aim of our investigation was to create a three-dimensional image of the primary cleft nasal deformity with a video scanner and to carry out linear measurements. MATERIAL ANDMETHODS:
Facial plaster casts of 19 patients with uni- and bilateral cleft lip and palate before primary lip repair were scanned with digital surface photogrammetry DSP 400. The width of the nose and of the nostril floor, the distance of the alar bases, the length of the ala, and the nasal tip protrusion were measured.RESULTS:
Imaging was possible without problems in all models. Direct measurements of the model correlated well with the results of the three-dimensional image. Significant dimensional differences of the nasal parameters examined were noted, depending on the cleft type.DISCUSSION:
A video-supported surface scanner allowed immediate three-dimensional imaging of the face. The computer software analyzed the generated surface exactly. The data measured with the presented system resembled other previously published results.
