OBJECTIVES/HYPOTHESIS: This study aimed to describe the diagnosis and management of congenital dilation of Stensen's duct (CDSD) in seven cases.
Retrospective study.
We collected data including medical records, radiology, and histopathology findings and follow-up for seven patients (four males) with CDSD. The mean age was 23.9 years (range, 2-72 years).
The clinical features of CDSD were the primary presentation of painless swelling in the cheek without an obvious cause that was unilateral or bilateral and occurred at any age, and a swelling along Stensen's duct. In patients without a history of inflammation, aggressive massage of the swelling could produce abundant intraoral salivary flow. Parotid sialography demonstrated a dilated Stensen's duct with a smooth margin but no obvious obstruction. All seven patients underwent superficial parotidectomy including the intact Stensen's duct. No patient showed recurrent swelling after a follow-up of 6 to 65 months.
CDSD is an uncommon congenital disorder of the parotid gland. Management with parotidectomy is effective.
目的/假说：本研究旨在描述 7 例先天性 Stensen 管扩张症（CDSD）的诊断和治疗方法。
回顾性研究。
我们收集了 7 例（4 例男性）CDSD 患者的病历、影像学和组织病理学检查及随访资料。平均年龄为 23.9 岁（范围，2-72 岁）。
CDSD 的临床特征为单侧或双侧无明显原因的无痛性面颊肿胀，可发生于任何年龄，且沿 Stensen 管出现肿胀。在无炎症病史的患者中，对肿胀进行积极按摩可产生大量的口腔内唾液流。腮腺造影显示 Stensen 管扩张，边缘光滑，但无明显阻塞。7 例患者均行包括完整 Stensen 管在内的腮腺浅叶切除术。随访 6 至 65 个月后，无患者出现复发性肿胀。
CDSD 是一种罕见的腮腺先天性疾病。采用腮腺切除术治疗效果良好。
