Abstract
INTRODUCTION: Traditionally, galeal flap or cranialization was often used to reconstruct the skull base defect caused by trauma or tumor removal. However, in the case of huge skull base defect, galeal flap is not enough to block the communication between nasal cavity and intracranial space. In this study, authors suggest combination flap of galea and reverse temporalis muscle as a method for reconstruction of huge skull base defect. MATERIALS AND METHODS: From 2016 to 2019, retrospective review was conducted, assessing 7 patients with bone defect which is not just opening of frontal sinus but extends to frontal sinus and cribriform plate. Reconstructions were done by combination of galeal flap and reverse temporalis muscle flap transposition. RESULTS: Defects were caused by nasal cavity tumor with intracranial extension or brain tumor with nasal cavity extension. There was no major complication in every case. During the follow up period, no patient had signs of complication such as ascending infection, herniation and CSF rhinorrhea. Postoperative radiologic images of all patients that were taken at least 6 months after the surgery showed that flaps maintained the lining and the volume well. DISCUSSION: Conventional reconstruction of skull base defect with galeal flap is not effective enough to cover the large sized defect. In conclusion, galeal flap in combination with reverse temporalis muscle flap can effectively block the communication of nasal cavity and intracranium.
