摘　　要：目的探讨超声诊断慢性颌下腺炎的价值。方法结石型颌下腺炎组患者25例,非结石型颌下腺炎组患者11例,共39处病变;超声观察颌下腺的大小、形态、边界、腺体回声及血流分布特征,腺管有无扩张,腺管内有无结石,周围软组织、颌下区淋巴结和邻近唾液腺有无累及。结果结石型颌下腺炎组均为单侧发病;19例颌下腺形态饱满,18例颌下腺导管扩张伴结石,7例腺体内结石,3例腺体内及颌下腺导管内结石并存。非结石型颌下腺炎组,8例单侧病变,6例双侧病变;11例颌下腺形态饱满,腺体回声偏低、不均匀,呈＂结节样＂改变,＂结节＂大小3~15 mm。其中,6例颌下腺＂结节＂相互融合形成低回声＂肿块＂。腺体内血流丰富,但血管走行正常。病变颌下腺不伴导管扩张或结石。结论超声检查对于慢性颌下腺炎的诊断和治疗具有重要的参考意义,是一种有效的检查方法。Objective To evaluate the diagnostic value of ultrasonography for chronic submandibular sialadenitis. Methods A total of 36 patients with chronic submandibular sialadenitis were involved in this study, 25 of them were calculous and 11 patients were acalculous. Ultrasonography was performed in submandibular glands for assessment of size, shape, border, and echogenicity, presence of dilated ducts or other intraglandular lesions, inflammatory changes in adjacent tissues, lymphadenopathy, and involvement of other salivary glands. Results All patients with calculous sialadenitis were unilateral. Glands were plump in 19 patients. A main duct calculus and dilatation was found in 18 cases. Seven cases showed intraglandular calculus, and 3 cases showed both duct and intraglandular calculus. Among 14 patients with acalculous sialadenitis, 8 of them were unilateral and the other 6 were bilateral. Glands were plump in 11 cases, showed uneven hypoecho and nodular change with a size between 3 and 5 mm. In 6 of 11 cases, nodules merged together and formed hypoechonic masses. Rich blood supply was found in gland but vessels were nomal. No duct dilatation and calculus were found in diseased gland. Conclusion Ultrasonography could provide an important basis for diagnosis and treatment of chronic submandibular sialadenitis.
