Intracranial section of the glossopharyngeal and upper roots of the vagus nerves has been recommended, the cardiac dysrhythmia being controlled with atropine, isoprenaline, or transvenous pacemaker. Carbamazepine is known to relieve the pain of uncomplicated glossopharyngeal neuralgia.2 In our first patient the combination of carbamazepine and demand pacemaker abolished both pain and syncope wi...

BACKGROUND AND PURPOSE Tumors of the cranial nerve sheath constitute 5% to 10% of all intracranial neoplasms, yet few articles have described their CT and MR characteristics. We report the imaging findings in a relatively large series of schwannomas of the jugular foramen, contrasting them with other disease entities, especially vestibular schwannomas and tumors of the glomus jugulare. METHOD...

The jugular foramen is a depression on the medial and inferior surface of the petrous pyramid formed by temporal and occipital bones [1,2]. It extends anteriorly, laterally and inferiorly from the endocranium to the exocranium between the temporal and occipital bones. The foramen is divided into two parts by a fibrous or osseous bridge that connects the jugular spine on petrous part of the temp...

Glossopharyngeal insufflation is used by competitive breath-hold divers to increase lung gas content above baseline total lung capacity (TLC) in order improve performance. Whilst glossopharyngeal insufflation is known to induce hypotension and tachycardia, little is known about the effects on the pulmonary circulation and structural integrity of the thorax. Six male breath-hold divers were stud...

Mice lacking both the P2X2 and the P2X3 purinergic receptors (P2X-dblKO) exhibit loss of responses to all taste qualities in the taste nerves innervating the tongue. Similarly, these mice exhibit a near total loss of taste-related behaviors in brief access tests except for a near-normal avoidance of acidic stimuli. This persistent avoidance of acids despite the loss of gustatory neural response...

A rare cause of reflex syncope is metastatic cancers involving the head and neck. These can irritate the glossopharyngeal nerve and lead to glossopharyngeal neuralgia with associated syncope. This type of syncope is difficult to treat since it commonly involves both a vasodepressor and cardioinhibitory response, and typically requires removal of the irritative focus. We report a case of a 52-ye...
