[Non-surgical management of parotid gland and duct injuries: interest of botulinum toxin].

Salivary fistulas and sialoceles are rare complications of post-traumatic or postoperative parotid gland and duct injuries. Local injections of type A botulinum toxin represent a new and effective treatment for complications of these injuries, which is less invasive, stressful and lengthy than conventional methods. The authors report five cases in which three salivary fistulas and two sialoceles were successfully treated by botulinum toxin injections. The therapeutic protocol is described; it allows simple management of these complications and use of smaller doses than those described in the literature for treatment of sialoceles. The authors recommend use of botulinum toxin injections in first intention for management of salivary fistulas and sialoceles.
