The "Double-channel, Tunnel-like" Approach for Managing Zygomatic Arch Fractures.

Area of Science:

• Oral and Maxillofacial Surgery
• Plastic and Reconstructive Surgery
• Trauma Surgery

Background:

• Zygomatic arch fractures often require surgical intervention for optimal restoration.
• Traditional open reduction and internal fixation (ORIF) methods can involve extensive incisions and potential complications.

Purpose of the Study:

• To present a minimally invasive surgical approach for ORIF of zygomatic arch fractures.
• To evaluate the efficacy and safety of a novel preauricular incision technique.

Main Methods:

• A preauricular hairline incision was utilized to create a "double-channel tunnel-like" approach.
• This technique allowed for complete zygomatic arch exposure without special instruments or additional incisions.
• The method was applied to a patient with an unsuccessful closed reduction of a zygomatic arch fracture.

Main Results:

• The minimally invasive technique enabled precise reduction and robust fixation of the zygomatic arch fracture.
• Postoperative computed tomography confirmed satisfactory fracture alignment and fixation.
• The patient exhibited an inconspicuous scar and no observed injury to the frontal branch of the facial nerve.

Conclusions:

• The proposed preauricular minimally invasive approach offers a streamlined and effective method for zygomatic arch fracture ORIF.
• This technique provides excellent visualization, precise reduction, and satisfactory cosmetic results with minimal risk of nerve injury.
