Although facial nerve paralysis has been reported in association with amyloidosis, histologic confirmation of facial nerve involvement with amyloid has not been previously demonstrated. A case of localized primary amyloidosis of the facial nerve is presented, and a new magnetic resonance technique for imaging the facial nerve is described.

Chronic parotitis is a disorder characterized by recurrent painful swelling of the gland with purulent sialorrhea. Occasionally, the condition fails to respond to medical management and definitive surgical therapy is necessary. Sialolithiasis is the usual etiology in cases of parotitis, although occasionally severe recurrent parotid infections are superimposed on underlying Sjögren's disease. Total parotidectomy with facial nerve dissection has been used in such cases in our department and has proved to be an excellent way to manage this disease. A summary of our results indicate that the recurring infections were eradicated and that the complication rate is tolerable, considering the magnitude of the problem. We feel that it is better to use surgical management early rather than wait for the formation of fistulae or abscesses.

Acalculous inflammation of the parotid gland has been regarded by some as a specific disorder that can be staged as to the severity of the disease process. A review of the literature, however, indicates a divergence of opinion. It is the purpose of this study to test this hypothesis by a retrospective double-blind analysis of clinical, sialographic and histopathologic findings. Forty-two patients who were seen by the Department of Otolaryngology, Washington University School of Medicine from 1961 to 1970 were evaluated by two separate teams. There were 20 sialograms and 30 pathologic specimens, and all were re-examined. Eleven patients had both sialographic studies and histopathologic examination. The clinical presentations and sialographic findings were reviewed. These findings were then compared to each other. Our results indicate that we could not evaluate the severity of the clinical disease by sialography or histopathology. There was no consistent method of staging the sialographic and pathologic findings. In addition, there was no correlation between these two parameters. They reflect neither the patient's clinical syndrome pattern nor the extent of disease. It appears that the parotid gland responds variable to inflammation. These observations are exemplified by case histories.

A 25-year retrospective study of 63 pediatric surgical cases of benign parotid disease was done. Inflammatory disorders accounted for 34 of the cases. The remaining 29 non-inflammatory conditions included vasoformative, solid, and cystic lesions and were nearly always asymptomatic.
