This is to report the histo-pathologic findings of the degenerated inferior alveolar
nerves(IAN) causing uncontrollable neuralgia persisted for over 3 years.
The patients had sufferred from frequent attack of unbearable pain along the
mandibular branches of the Vth nerve. The pain arised spontaneously 5-10 times a day
and lasted for 2-5 minutes. The medications including Tegretol were
neither so effective to alleviate the pain level, nor enough to keep free from pain all
days.
The peripheral neurectomies were preceded by diagnostic nerve block, and partial
resection of the IAN in the mandibular canals were approached by sagittal split osteomy
of the ramus.
The histopathologic findings of the resected IAN were as follows ;
1. Special staining with Luxol Fast Blue (LFB) and Masson Trichrome (MT) disclosed
marked degeneration of the axons, decreased in number and fibrosis between the nerve
fibers.
2. EM study revealed destruction of myelin continuity surrounding axons, degeneration
of Schwann cell and endoneureal sheath, and coarse collagen between the destructed
axons.
3. The 3 of 6 patients presented again with recurred pain in 2-3 years after the
peripheral neurectomies. Excisional biopsy of the retromolarpterygomandibular softtissues
disclosed the collateralization neuropathy beside the long-buccal nerves and their
neuromatous findings.
