Grading Facial Nerve Function Following Combined Static and Mimetic Surgical Techniques

Area of Science:

• Otolaryngology
• Neurosurgery
• Plastic Surgery

Background:

• Facial nerve injuries often require complex surgical reanimation techniques.
• Existing grading scales may not adequately assess functional recovery in all patient populations, particularly those with non-anatomically intact nerves.
• Accurate assessment is crucial for guiding treatment and evaluating outcomes in facial reanimation.

Purpose of the Study:

• To introduce a novel grading scale for evaluating functional recovery of the facial nerve.
• To provide a practical tool for clinicians managing patients after mimetic and static facial reanimation procedures.
• To address the need for an efficient assessment method in a unique patient cohort.

Main Methods:

• Development of a new, proposed facial nerve grading system.
• Demonstration of the grading scale using specific case presentations.
• Application of the scale to patients who underwent neural grafting, microvascular free-flap reconstruction, or static surgical procedures.

Main Results:

• The proposed grading scale is novel and has not been previously described in the literature.
• The scale is specifically designed for and applicable to a unique patient population undergoing facial reanimation.
• The scale facilitates accurate and rapid assessment of facial nerve recovery by otolaryngologists.

Conclusions:

• The new facial nerve grading scale offers an efficient method for assessing recovery in patients previously difficult to follow.
• The scale is practical and user-friendly for clinical settings.
• This tool enhances the ability to monitor and manage functional outcomes after facial reanimation surgery.
