We report a case of tooth loss and alveolar bone necrosis secondary to herpes zoster in the region innervated by the third branch of the trigeminal nerve. The patient was a 74-year-old man who was referred to our department with chief complaints of tooth loss and exposure of the alveolar bone in the left mandible. He had a history of herpes zoster of the trigeminal nerve and had spontaneous loss of the left mandibular second premolar and first molar approximately 2.5 months and 1.5 months before his first visit, respectively. Initial examination revealed exposure of the alveolar bone of the two affected teeth, with gingival swelling and flare. In addition, paresthesia was present in the region innervated by the third branch of the left trigeminal nerve, for which a dermatologist had prescribed vitamin B12. Antibacterial treatment with local irrigation was performed after initial presentation. Five weeks after his first visit, we observed the elimination of a sequestrum. Currently, the exposed bone has disappeared, and the patient's disease course has been uneventful. The pathological diagnosis was bone necrosis associated with infection.

The tumor extension of T4 cases of upper gum carcinoma (UG-Ca) is clinically similar to T2 cases of maxillary sinus carcinoma (NIS-Ca). However, the prognosis of the former is remarkably unfavorable compared with the latter. A comparative study between 16 cases of UG-Ca (T4) and 14 cases of MS-Ca (T2) was undertaken in order to assess the difference in their prognosis.<BR>The 5 year accumulative survival rate of UG-Ca (T4) was 36.5% and MS-Ca (T2) was 92.3%. While the control rate of the primary lesion after initial therapy, the former was 50% and the latter was 78.6%. As for the rat of cervical metastases noted clinically, it was 75% and 35.7% respectively. Bilateral cervical metastases was noted in 6 cases of UG-Ca (T4) and none in MS-Ca (T2). With respect to the 5 year accumulative survival rate of the cases with pathologically confirmed nodal involvement, it was 0% for UG-Ca (T4) but MS-Ca (T2) was 66.7%.<BR>The unfavorable prognosis for UG-Ca (T4) cases was attributed to failure to control primary and cervical metastases. Therefore, it is necessary to reexamine the margin of the primary resection and the timing for carrying out RND.
