The perimeatal exposure of the condyle

Area of Science:

• Oral and Maxillofacial Surgery
• Neurosurgery
• Anatomy

Background:

• The glenoid fossa is a critical anatomical structure in the temporomandibular joint.
• Surgical access to the glenoid fossa can pose risks to surrounding neurovascular structures.
• Previous surgical approaches may lead to complications such as facial nerve injury or post-operative stenosis.

Purpose of the Study:

• To describe a novel surgical technique, the perimeatal approach, for accessing the glenoid fossa.
• To evaluate the safety and efficacy of the perimeatal approach in preventing specific surgical complications.

Main Methods:

• The perimeatal approach combines preauricular and postauricular incisions.
• This technique avoids excessive anterior tissue retraction to protect the frontal branch of the facial nerve.
• The cartilaginous meatus is intentionally not transected during the procedure.

Main Results:

• The perimeatal approach provides effective access to the glenoid fossa.
• Damage to the frontal branch of the facial nerve is avoided due to minimal tissue retraction.
• Transection of the cartilaginous meatus is prevented, mitigating risks of stenosis and infection.

Conclusions:

• The perimeatal approach is a safe and effective method for glenoid fossa surgery.
• This technique minimizes the risk of facial nerve injury and post-operative complications.
• Preservation of the cartilaginous meatus is a key advantage of the perimeatal approach.
