GLOMUS TYMPANICUM: AN OVERVIEW
Nội dung chính của bài viết
Tóm tắt
ABSTRACT
Objective: To review the clinical, radiological, and therapeutic characteristics of glomus tympanicum tumors, providing an updated overview of current diagnostic and treatment approaches in Vietnam and internationally. Methods: A comprehensive literature review was conducted using publications from 2010–2025 retrieved from databases including PubMed, Scopus, ScienceDirect, and Vietnamese Otorhinolaryngology journals. Studies were synthesized and compared based on specific criteria: epidemiology, clinical presentation, imaging features (CT–MRI), treatment modalities, and complications. Results: Glomus tympanicum is a benign, slow-growing vascular tumor, predominantly affecting middle-aged women. The primary symptoms are pulsatile tinnitus and conductive hearing loss. High-resolution CT and MRI play crucial roles in definitive diagnosis, staging, and surgical planning. Surgical excision remains the mainstay of treatment, achieving tumor control rates exceeding 90%. Preoperative embolization and endoscopic ear surgery (EES) have been shown to minimize intraoperative bleeding, reduce complications, and improve hearing preservation. The most common postoperative complications are transient hearing loss and residual tinnitus; facial nerve palsy is rare (<8%) and typically reversible. Conclusion: Early diagnosis facilitated by advanced imaging and otoscopic evaluation significantly improves treatment outcomes. Current trends favor minimally invasive approaches, specifically combined endoscopic–microscopic surgery, which demonstrates high efficacy. Further multicenter studies are recommended for long-term outcome assessment and recurrence monitoring
