Quantitative ultrasound imaging of healthy and reconstructed cleft lip: a feasibility study.

Objective: To investigate the feasibility of echographic imaging of healthy and reconstructed cleft lip and to estimate tissue dimensions and normalized echo level.

Methods: Echographic images of the upper lip were made on three healthy subjects and two patients using a linear array transducer (7 to 11 MHz bandwidth) and a noncontact gel coupling. Tissue dimensions were measured using calipers.

Dental age in children with a complete unilateral cleft lip and palate.

Objective: To assess dental age in children with a complete unilateral cleft lip and palate and to compare this with a noncleft control group.

Design: Two-group, mixed-longitudinal cohort study.

Setting: Cleft group from an academic center for cleft lip and palate treatment.
