Purpose

This study evaluates anthropometric outcomes of a modified Onizuka technique for unilateral cleft lip (cleft lip) repair using 3-dimensional (3D) photogrammetry, with emphasis on anatomic subunit reconstruction without preoperative numerical measurements.

Methods

A prospective cohort study was conducted at a tertiary craniofacial center.

<0.2 mm

Results

<0.2 mm

cleft and noncleft sides matched below what the human eye can detect

More results

The cohort comprised 60.7% males, with 70.5% having left-sided clefts and 67.2% having complete clefts.

Median age at surgery was 5.0 months.

All intraclass correlation coefficient values exceeded 0.75, indicating good to excellent reliability.

No statistically significant differences were observed between cleft and noncleft sides (all P>0.05).

Conclusion

The modified Onizuka technique achieves symmetric outcomes in unilateral cleft lip repair, validated by objective 3D metrics.
