BACKGROUND
The purpose of the present study was to compare and contrast the clinicopathological features and treatment outcome of chronic sialadenitis involving the parotid and submandibular glands, among patients who were treated by excision of the affected gland.
METHODS
In a series of 88 patients treated over an 8-year period, 47 had parotid sialadenitis and 41 had submandibular sialadenitis. In the parotid group, 63% of patients were symptomatic for longer than 6 months compared with 27% in the submandibular group. Calculi were implicated in the disease process in 24% of patients with parotid sialadenitis, compared with 73% of patients with submandibular disease.
RESULTS
Patients with parotid sialadenitis had superficial (n = 14) or near-total parotidectomy (n = 35), while those with submandibular sialadenitis underwent total gland excision. Complications occurred twice as frequently in the parotidectomy group. The rate of temporary facial nerve weakness was 29% after parotidectomy while marginal mandibular nerve dysfunction occurred after 12% of submandibular excisions. Both procedures were highly effective in permanently relieving the symptoms of sialadenitis.
CONCLUSIONS
Parotid sialadenitis is infrequently associated with stones and tends to run a longer course before surgical intervention is necessary. Submandibular sialadenitis usually presents earlier, is secondary to calculi and requires early intervention.
