A Case of Parotid Gland Fistula After Microtia Reconstruction Successfully Treated With Botulinum Toxin Type A.

Parotid gland fistula after microtia reconstruction is relatively rare, with only 3 cases having been reported in the literature. It may be caused by the presence of an accessory parotid gland or surgical damage to parotid gland tissues. The principal treatment is dressing the wound. Here, we report the first case of parotid fistula after microtia reconstruction using a delayed retroauricular flap, which healed following wound dressing and an injection of botulinum toxin type A (CBTXA) into the parotid gland.
