Unilateral Cleft Lip Repair Using Anatomical Subunits

Unilateral cleft lip repair aims to restore normal lip form, symmetry, and function while minimizing visible scarring and long-term deformity. The anatomical subunits technique "Fisher Technique" applies principles of aesthetic subunit reconstruction to cleft lip repair, emphasizing precise restoration of the philtral column, Cupid’s bow, vermilion, and nasal sill. This video presents a step-by-step demonstration of unilateral cleft lip repair using the anatomical subunits approach, highlighting preoperative marking, subunit-based incision design, and layered reconstruction of the orbicularis oris muscle.

Key operative steps include accurate identification of lip markings, technique of marking landmarks and the dissection and execution of the procedure are heighlighted. Technical nuances for achieving symmetric Cupid’s bow peaks, balanced vermilion height, and improved nasal base alignment are emphasized.

The anatomical subunits technique offers a reliable and aesthetically driven method for unilateral cleft lip repair, facilitating improved lip symmetry, natural scar concealment, and durable functional outcomes. This video is intended as an educational resource for trainees and practicing surgeons seeking a structured, anatomy-based approach to primary cleft lip reconstruction.
