Traumatic injuries in the parotid region.

Area of Science:

• Otolaryngology
• Plastic Surgery
• Emergency Medicine

Background:

• The parotid region is vulnerable to penetrating trauma.
• Injuries can affect critical structures including the facial nerve, parotid duct, and external ear canal.

Purpose of the Study:

• To outline the immediate management of penetrating injuries to the parotid region.
• To emphasize the importance of preserving facial nerve function, parotid duct patency, and external ear canal integrity.

Main Methods:

• Clinical assessment of facial nerve branches in the emergency department.
• Electronic stimulation for assessing distal facial nerve viability.
• Probing and repair of parotid duct lacerations.
• Surgical repair and stenting of the external ear canal.

Main Results:

• Early identification and repair of facial nerve injuries allow for timely intervention.
• Parotid duct injuries can be successfully managed with probing and repair.
• External ear canal repair and stenting effectively prevent post-injury stenosis.

Conclusions:

• Prompt and thorough management of penetrating parotid injuries is essential.
• A systematic approach ensures the preservation of facial nerve function and anatomical structures.
• Preventing complications like facial nerve paralysis and ear canal stenosis is achievable with appropriate surgical techniques.
