Management of Acute Facial Nerve and Parotid Injuries.

Area of Science:

• Plastic Surgery
• Otolaryngology
• Emergency Medicine

Background:

• Acute head and neck soft tissue trauma frequently leads to emergency department visits.
• Facial nerve and parotid duct injuries can cause significant long-term morbidity if diagnosis is delayed.

Purpose of the Study:

• To provide a guide for evaluating and managing facial trauma, specifically focusing on facial nerve and parotid duct injuries.
• To discuss relevant anatomy, treatment decisions, risks, benefits, and complication management.

Main Methods:

• Review of relevant anatomical structures of the facial nerve and parotid duct.
• Discussion of diagnostic considerations, including a comprehensive facial nerve examination and suspicion for parotid duct injury.
• Outline of surgical repair techniques for facial nerve transection (neurorrhaphy) and parotid duct injuries.

Main Results:

• Neurorrhaphy outcomes depend on tension-free anastomosis and timely repair.
• Parotid duct repair strategies are site-dependent.
• Management of complications associated with facial nerve repair and parotid duct injuries is detailed.

Conclusions:

• Prompt and accurate evaluation by facial plastic surgeons is essential for patients with facial trauma.
• Understanding facial nerve and parotid duct anatomy and injury patterns guides effective treatment and improves patient outcomes.
