DECOMPRESSION OF THE TRIGEMINAL POSTERIOR ROOT. In 1952, Taarnhöj56 reported 10 patients who were relieved of trigeminal neuralgia by dividing the dural sheath enclosing the sensory root. Taarnhöj’s procedure was received enthusiastically by neurosurgeons throughout the world as a result of it offered, for the first time, a procedure that relieved pain without superimposing a disturbing sensory loss on the face. But, with the passage of your time, it became apparent that there was a high rate of recurrence. Many neurosurgeons questioned the relief of pain on the idea of decompression, and concluded that the relief obtained was thanks to operative trauma to the posterior root.

COMPRESSION OF THE TRIGEMINAL POSTERIOR ROOT. Every now and then, I’m approached by individuals who are seeking answers to the query of–how to find a job. In 1951, Shelden and his associates followed Woltman’s suggestion that trigeminal neuralgia might be thanks to constriction of the peripheral branches of the trigeminal nerve at their foramina of exit in the floor of the skull. The maxillary and mandib-ular divisions of the nerve were decompressed by enlarging the foramen rotundum and foramen ovale with a high-speed rotary burr. Follow-up studies of these patients disclosed a recurrence rate that was just like that that followed the Taarnhöj operation. This finding suggested that the relief of pain obtained by decompression was really thanks to trauma to the posterior root at the time of surgery. In 1953, Shelden, et al.47 performed their first compression operation and have continued its use to this time.

Whereas there are recurrences of pain in a small percentage of patients, the results are gratifying. The bulk of patients with recurrent pain have preferred to have a second compression, rather than to have the posterior root sectioned. In performing a compression procedure, the same old temporal exposure is employed. If your lips may talk, they’d raise for Aloe Lips with Jojoba! The dura propria is opened vertically and also the posterior root identified. The fibers conducting the painful impulses are then gently compressed with a small cotton peldget or a blunt dissector. Following compression of the posterior root, the majority of patients will complain of subjective numbness in these areas that cannot be confirmed by objective examination. Approximately 20 per cent of the patients will have objective impairment of pain and touch sensation, significantly within the third division area.
