Reconstruction of Scalp and Calvarial Defects Using Latissimus Dorsi Myocutaneous Free Flap

Purpose: Reconstruction of scalp and calvarial defects should provide both aesthetic and functional aspects. The inelastic nature of the scalp and previous surgery or radiation preclude the use of primary closure or a local flap. With development of microsurgical technique, a free tissue transfer is a good option. We use the latissimus dorsi myocutaneous free flap for reconstruction. Materials and Methods: A review of all latissimus dorsi free flap reconstructions performed in nine patients from 2009 to 2012 was conducted. There were six males and three females, ranging in age from seven to 69 years, and nine different regions, including five temporal regions, two occipital regions, and two frontoparietal regions. The flaps ranged in size from $9.0{\times}10.0cm$ to $14.0{\times}15.0cm$. Recipient vessels available for microanastomosis were most often the superficial temporal vessels and two patients had anastomoses to the external carotid artery and internal jugular vein. Results: All flaps survived postoperatively. With a median follow-up period of 14 months, no major complications were noted. However, two patients developed minor wound dehiscence, and a hematoma was observed in one patient. Conclusion: We performed the latissimus dorsi myocutaneous free flap reconstruction, which is one of the most popular reconstructive methods. The latissimus dorsi myocutaneous free flap reconstruction has been proven successful in our patients with satisfactory results. During the long term follow-up period, even though depressions were observed on the defect area in some patients, they were treated successfully with cranioplasty. Therefore, we recommend the latissimus dorsi myocutaneous free flap for reconstruction of scalp and calvarial defects.
