OBJECTIVE: To quantify comparative improvement between osseous and soft tissue asymmetry following primary lip repair.
DESIGN: Retrospective analysis of preoperative and postoperative computed tomography scans of infants with unilateral cleft lip and palate. Sixteen soft tissue landmarks were placed using an exploratory two-/three-dimensional image processing system and compared for asymmetry.
PATIENTS: Computed tomography scans were obtained on 26 patients (13 boys, 13 girls) of Chinese ethnicity (mean age = 0.25 years) prior to Millard lip repair. Nineteen of these contributed to follow-up comparative studies prior to palatoplasty at a mean age of 0.92 years. There were 18 left-sided and eight right-sided clefts.
MAIN OUTCOME MEASURE: Euclidean distance matrix asymmetry analysis was used to determine the amount of soft tissue asymmetry pre- and postlip repair. Similar analyses of the same scans were performed for 41 osseous landmarks.
RESULTS: Soft tissue landmarks had 36/39 (92%) preoperative and 13/39 (33%) postoperative asymmetric pairs. Osseous distances demonstrated 77/125 (61%) asymmetric pairs preoperatively and 60/125 (48%) postoperatively. Soft tissue and osseous distances of the lip region demonstrated 32% and 39% postoperative asymmetry, respectively. Soft tissue and osseous distances of the nasal region demonstrated 52% and 72% postoperative asymmetry, respectively. Soft tissue and osseous distances of the facial landmarks demonstrated 24% and 34% postoperative asymmetry, respectively.
CONCLUSIONS: Primary lip repair appears to effect gains in symmetry in soft tissue and provides sufficient molding forces to cause correlating symmetry changes in underlying osseous structures.
