Subcranial-supraorbital and temporal approach for tumor resection

Area of Science:

• Neurosurgery
• Craniofacial Surgery
• Skull Base Surgery

Background:

• Fronto-orbital tumors present complex surgical challenges.
• Traditional transcranial approaches may have limitations in exposure and reconstruction.
• Skull base reconstruction requires robust techniques for optimal outcomes.

Purpose of the Study:

• To describe the advantages of the subcranial approach over the transcranial approach for fronto-orbital tumor resection.
• To illustrate reconstruction and fixation techniques for bone grafts.
• To emphasize methods for reconstructing critical anatomical structures.

Main Methods:

• Detailed description of the subcranial surgical approach.
• Illustration of primary reconstruction and fixation using miniplates or wire ligatures.
• Application of lyophilized cartilage and Biocement for orbital roof and skull base defect repair.

Main Results:

• The subcranial approach offers superior exposure for fronto-orbital tumors and skull base.
• Effective reconstruction of bone defects using miniplates, wire ligatures, lyophilized cartilage, and Biocement.
• Successful reconstruction of the temporomandibular joint fossa in extensive resections.

Conclusions:

• The subcranial approach is advantageous for fronto-orbital tumor resection and skull base exposure.
• Various materials and techniques facilitate reliable bone graft fixation and defect reconstruction.
• This approach enables comprehensive management of complex craniofacial defects.
