Treatment of Pulsatile Tinnitus Associated with Multiple Factors

引用

Chinese Medical Journal 2015年第3期128卷 413-414页

作者： Xiao-Bo Ma Guo-Peng Wang Rong Zeng Shu-Sheng Gong Department of Otolaryngology Head and Neck Surgery Beijing Tongren Hospital Capital Medical University Beijing 100730 China

Numerous factors may lead to pulsatile tinnitus （PT）, including atherosclerosis, benign intracranial hypertension, glomus tympanicum tumor, dural arteriovenous fistulas （dAVFs）, abnormalities of the sigmoid sinus （dehiscence and diverticulum）, and jugular bulb anomalies （glomus jugular tumor, diverticulum, high-riding or dehiscent jugular bulb）. However, exact causes often cannot be found in many patients even after a detailed physical examination and extensive auxiliary examinations. Moreover, no effective treatment is available for these patients. Patients with PT associated with multiple factors are seldom reported, and the condition is essentially intractable. Here, we reported three cases with PT involving multiple factors.
