Preauricular approach to infratemporal fossa.

Area of Science:

• Neurosurgery
• Surgical Oncology
• Anatomy

Background:

• Skull base surgery requires specialized approaches for accessing critical anatomical regions.
• Minimizing surgical morbidity and preserving neurological function are paramount in skull base procedures.

Observation:

• A new surgical technique is described for skull base access.
• The approach employs a preauricular incision, zygomatic arch division, and coronoid process manipulation.
• Facial nerve preservation and avoidance of mastoidectomy are key features.

Findings:

• This method allows simultaneous access to the infratemporal fossa and middle cranial fossa.
• Reconstruction involves temporalis muscle or pericranial flaps, fat grafts, and internal wiring for skeletal fixation.
• The technique was successfully applied to cases involving both benign and malignant lesions.

Implications:

• This approach offers a potentially less morbid alternative for skull base tumor resection.
• It may improve functional outcomes and reduce postoperative complications.
• Further studies can validate its efficacy and expand its application in skull base surgery.
