Karapandzic Flap Technique

Abstract

The reconstruction of lip defects poses a surgical challenge, especially when malignancies affecting the oral commissure require extensive excisions leading to considerable tissue loss. Optimal reconstruction methods must restore functionality, maintain aesthetics, and harmonize with adjacent tissues. The Karapandzic flap, introduced in 1974, provides a neurovascular myocutaneous technique that safeguards essential structures while preserving lip mobility and sensation.
This report emphasizes the reconstruction of a substantial lip defect subsequent to the excision of basal cell carcinoma utilizing the Karapandzic flap. The technique offers benefits such as a single-stage procedure, maintenance of vascular and nerve networks, and enhancement of oral function with increased lip mobility. Notwithstanding possible drawbacks like temporary microstomia and asymmetry of the oral commissure, the Karapandzic flap provides enhanced functional and aesthetic results relative to alternative techniques. This method proficiently targets the intricate musculature at the oral commissure, delivering a substantial functional reconstruction while circumventing the rigidity and diminished sensation linked to alternative techniques.
The Karapandzic flap is a dependable and effective method for reconstructing substantial lip defects, including those affecting the oral commissure. Although early postoperative microstomia may arise, it generally ameliorates with time, rendering this technique a commendable option for attaining optimal functional and aesthetic outcomes in lip reconstruction.
