Skull base reconstruction after anterior craniofacial resection
1Unit of Cranio-Maxillofacial Surgery, Istituto Nazionale per lo Studio e la Cura dei Tumori, Milano, Italy.
Summary
For anterior skull base defects after craniofacial resection, a pedicled pericranial flap is recommended. This method effectively prevents complications like brain herniation and CSF leakage.
Area of Science:
- Neurosurgery
- Otolaryngology
- Head and Neck Surgery
Background:
- Anterior craniofacial resection is a common procedure for nasoethmoid tumors involving the skull base.
- Reconstruction methods for anterior skull base defects remain a subject of debate.
- Techniques have evolved from simple closures to complex reconstructions using flaps and augmentation.
Purpose of the Study:
- To evaluate different reconstruction methods for anterior skull base defects following resection.
- To determine the optimal approach for preventing complications such as brain herniation, infection, and cerebrospinal fluid (CSF) leakage.
Main Methods:
- Review of relevant literature on anterior skull base reconstruction.
- Analysis of clinical experience from 168 anterior craniofacial resections.
- Comparison of outcomes associated with various reconstruction techniques.
Main Results:
- Various reconstruction methods exist, including galeal-pericranial flaps, free flaps, and bony/alloplastic augmentation.
- The primary goals of reconstruction are to prevent brain herniation, intracranial infections, CSF leakage, and pneumocephalus.
- Clinical experience suggests a pedicled pericranial flap is a highly effective method.
Conclusions:
- A pedicled pericranial flap is the preferred method for closing anterior skull base defects after resection.
- This technique offers a reliable solution for preventing major postoperative complications.
