For permanent relief of pain in patients suffering from glossopharyngeal neuralgia, the glossopharyngeal nerve (ninth cranial nerve) is divided intracranially.* Not only does this operative procedure control the pain in the area supplied by the ninth nerve but it also results, apparently, in little or no objective sensory deficit. In several papers † it has been stated, however, that the operation produces considerable loss of sensation in the area of the posterior part of the pharynx and the tonsillar fossa, believed to be supplied by the ninth cranial nerve. Anatomic studies have been presented which demonstrate rather extensive loss of appreciation of touch, pain, and temperature in the posterior part of the pharynx after isolation and section of the ninth nerve (Fig. 1). In some papers ‡ it has even been suggested that difficulties of deglutition may be a postoperative sequel, with fluids running out of the nostril. The latter
