Purpose: Skull base reconstruction is one of the most difficult reconstructive surgical procedures. Due to its complexity, most surgeons have modified the reconstruction methods to minimize the postoperative complications and mortality rate. In the past, flap surgery was not usually performed, but it has recently become more common due to advances in medicine. In this study, we analyzed successful flap surgery methods in skull base reconstruction for large cranial-nasal communications.
Methods: Patients who underwent skull base reconstruction from April 2015 to January 2024 were eligible for this study. Of these patients, we included those who underwent reconstruction using a volumetric flap. Reconstructions that only used the conventional galeal flap, allograft skin, or bone substitute were excluded. The reconstruction methods used local flaps and free flaps.
Results: In total, 22 patients underwent skull base reconstruction. The most frequently used local flap was the bilateral reverse temporalis muscle flap (seven of 11 cases), and the most frequent free flap was the anterior lateral thigh flap (10 of 11 cases). Other local flap operations used the modified temporalis muscle flap and scalp flap. A rectus myocutaneous flap was also used. There were no cases of flap necrosis.
Conclusion: Flap surgery is needed for skull base reconstruction in patients with large cranial-nasal communications. As long as the flap volume is large enough to block and fill the defect, either a local flap or a free flap can be used for reconstruction.
