Gustatory rhinorrhea after maxillectomy. Two case reports and considerations on etiology and pathophysiology.
Gustatory rhinorrhea consists of free discharge of thin mucus from the nose during ingestion or after other gustatory stimulus. At maxillectomy, the nerve fibers going both to the salivary glands of the palate and to the secretory glands of the nasal mucosa may be damaged. A misdirection between the regenerating fibers of these two groups produces gustatory rhinorrhea.
