Endoscopic diagnosis of rhino-parotid fistula and successful treatment with botulinum toxin.

abstract not available. Introduction: "Gustatory rhinorrhea (GR) consists of free thin discharge of mucus from the nose during meals or after a gustatory stimulus. Gustatory rhinorrhea has been reported after maxillectomy, parotidectomy, septoplasty, facial fractures, or trauma and also after the ingestion of spicy foods. Gustatory rhinorrhea may be due to misdirection of parasympathetic secretory fibers or to the opening of a parotid fistula in the nose or maxillary sinus, especially after facial fractures. Diagnostic workup in a case of GR following a maxillectomy with late reconstruction with cheek flap is reported. The GR was successfully treated with botulinum toxin A (BTX-A) injection on the parotid gland. The authors describe their therapeutic approach."
