Madarosis and facial alopecia presumed secondary to botulinum a toxin injections.

Abstract

PURPOSE:

: Botulinum neurotoxins are considered relatively safe therapy for treatment of inappropriate muscle spasms. As seen in this report, undesirable consequences may result.

METHODS:

: The author conducted a clinical interview and examination of the patient.

RESULTS:

: Unilateral left-sided madarosis and facial alopecia were observed in a patient undergoing botulinum A toxin injections for the treatment of left oromandibular dystonia. The patient had started treatment 18 months previously. He received injections every 3 months in the left masseter and left temporalis muscles. He first noted loss of his left sideburn 8 months into treatment. After 10 months of treatment, he noted that he no longer needed to shave on the left side of his face. Eighteen months after receiving his first botulinum toxin injection, madarosis of the temporal aspect of the left lower lid was observed.

CONCLUSIONS:

: This is the first case report documenting an idiosyncratic unilateral madarosis and facial alopecia as adverse side effects presumed secondary to botulinum A toxin injections.
