Facial palsy (FP) is one of the most common neuropathies. 15-30% of patients develop chronic sequelae. Several studies support the use of botulinum toxin A (BoNT-A) in the treatment of FP sequelae. No studies have analysed the cost of treating FP with BoNT-A.

A retrospective review of data from all clinical records of consultations and procedures that took place at the FP Treatment Unit clinic throughout 2017. Type of BoNT-A used, total dose used, unilateral or bilateral injection, date of consultation, and gender were collected. The price of expendable materials, BoNT-A, and the 2017 salary scale was obtained to established costs.

During 2017, 605 clinical procedures were conducted in 240 patients. The mean number of procedures was 2.5(0.80). The average time between procedures was 124(28.72) days.The total annual cost was 34.155,10€. The average annual cost of BoNT-A for each procedure was 39,93€, and the total annual cost of BoNT-A 24.160,58€.On average, more units of IncotoxA were injected. This difference is not reflected in the final cost of each BoNT-A. For patients that achieved treatment stability, the average annual cost per patient was 106,6€ (OnatoxA) and 100,6€ (IncotoxA).

In our Unit, treatment with BoNT-A in FP sequelae had an average annual cost of 124,31€ per patient, requiring a visit to the hospital to receive treatment every 124 days. Given the functional and quality of life improvements, we should consider that it is a beneficial treatment at an acceptable cost.
