Facial nerve dysfunction is a common complication after vestibular schwannoma (VS) resection. Traditional grading scales such as House-Brackmann (HB), Sunnybrook, and Fisch are subjective and prone to inter-rater variability. Emotrics, a computer vision-based tool, offers objective facial analysis, but its role in neurosurgical populations remains underexplored.
Quantitative facial analysis with Emotrics shows promise as an objective measure of facial nerve outcomes after vestibular schwannoma surgery, but clinicians should await larger validation studies before replacing established grading scales in routine practice.
Objective, software-based facial nerve assessment could standardize outcome measurement after vestibular schwannoma surgery, reducing the subjectivity of current clinical grading systems used across neurotology and skull base surgery teams.
