[Abstract] PURPOSE: To analyze a single institution’s experience of solitary venous malformation (VM) in the accessory parotid region. METHODS: From 2002 to 2009, a total of 10 consecutive patients with solitary venous malformation (VM) in the accessory parotid region were retrospectively analyzed. Clinical records were reviewed for patient demographic data, presenting symptoms and signs, imaging modalities used, histological and immunohistochemical results, surgical data, and clinical outcomes. RESULTS: The sample consisted of 5 males and 5 females with a mean age of 42.8 years. The course of disease ranged from 0.5 to 168.0 months with a mean time of 64.9 months. The mean size of the masses was 1.7 cm×1.5 cm (1.0 cm×0.8 cm to 2.5 cm×2.5 cm). Investigations included Doppler ultrasonography (US) and computed tomography (CT) scanning. Surgical excision using various surgical approaches was performed in all patients. Postoperative pathologic examination confirmed the diagnosis of VM. The mean follow-up period was 41.2 months (range 2 months to 94 months) with no recurrence reported. CONCLUSIONS: For solitary VM in the accessory parotid region, investigations, such as Doppler US or CT scanning or the use of fine needle aspiration cytology, may aid in clinical diagnosis. The primary treatment of these lesions is surgical excision, and the prognosis is good with fewer recurrence. Supported by National Natural Science Foundation of China(81272979).
