摘要

AIM: To evaluate feasibility of establishing a clinically applicable reference value through those unaffected salivary gland on sialoscintigraphic data obtained from patients presented with obstructive sialadenitis affected a single gland. MATERIALS AND METHODS: Ninety-one patients suffered from single salivary gland swelling, pain/tenderness and received sialoscintigraphic examinations were retrospectively enrolled. The quantitative data parameters, including the uptake ratio, maximal accumulation, maximal excretion, time to maximal (Tmax) and time to minimal (Tmin) activity of the affected and unaffected glands, were calculated for analysis. Data were also obtained and recorded for comparison from 50 patients who fulfill the American-European criteria for the diagnosis of Sjogren's syndrome. RESULTS: The maximal excretion appeared to be the best indicator for distinguishing affected and unaffected glands of obstructive diseases, for parotid and submandibular glands (P = 0.0002 and P < 0.0001, respectively). The area under the receiver-operating characteristic curve (AUC) is 0.82 for submandibular glands. In patients with Sjogren's syndrome, the maximal excretion and Tmin were the best parameters, for parotid (P = 0.002 and P < 0.0001, respectively) and submandibular glands (P < 0.0001 and P = 0.002, respectively). Uptake ratio was a good parameter for submandibular gland (P < 0.0001). The AUC of maximal excretion and uptake ratio for submandibular glands is 0.81 and 0.77, respectively. CONCLUSION: Quantitative data obtained from the unaffected glands of patients with obstructive sialadenitis could be used as reference values for the functional evaluation of salivary gland disorders with maximal excretion as one of the reliable parameters.
