Innervated musculocutaneous lip flap (Karapandzic technique)

Area of Science:

• Reconstructive surgery
• Oral and maxillofacial surgery
• Plastic surgery

Background:

• Full thickness defects of the lower lip can result from trauma or cancer resection.
• Reconstruction aims to restore form, function, and sensation.
• Existing techniques may compromise lip function or sensation.

Purpose of the Study:

• To evaluate the Karapandzic technique for lower lip reconstruction.
• To assess the functional and aesthetic outcomes of the Karapandzic technique.

Main Methods:

• The Karapandzic technique involves sliding and rotating a local flap.
• An intact neurovascular pedicle is maintained throughout the procedure.
• This technique is suitable for full thickness defects exceeding one-third of the lower lip.

Main Results:

• The Karapandzic technique is technically straightforward to execute.
• Excellent aesthetic and functional results were observed.
• Preservation of lip sensation, circulation, and orbicularis oris muscle function was achieved.

Conclusions:

• The Karapandzic technique is a reliable and effective method for reconstructing significant lower lip defects.
• It offers superior functional and sensory preservation compared to other methods.
• This technique should be considered for large full thickness lower lip defects.
