Total Endoscopic Approach in Glomus Tympanicum Surgery.

Area of Science:

• Otolaryngology
• Neurosurgery
• Surgical Oncology

Background:

• Glomus tympanicum (GT) is a benign vascular tumor originating in the middle ear.
• Endoscopic ear surgery presents an alternative management strategy for GT.
• This study evaluates the endoscopic transcanal approach for GT resection.

Purpose of the Study:

• To assess the efficacy of the endoscopic transcanal approach in managing glomus tympanicum.
• To determine the applicability and feasibility of this surgical technique.

Main Methods:

• Prospective study of 13 patients with Class I and II glomus tympanicum tumors.
• Tumor classification based on location: anterior (Group A), promontory (Group B), and entire middle ear (Group C).
• Tumor removal performed using a transcanal endoscopic approach with specialized flap elevation and hemostasis.

Main Results:

• Tumor distribution: 30% Group A, 46% Group B, 23% Group C.
• Pulsatile tinnitus resolved in most patients post-surgery.
• Mixed hearing loss was common; air conduction improved in 9 cases, with no change in bone conduction.
• No major complications or recurrence observed during 30 months of follow-up.

Conclusions:

• The endoscopic transcanal approach provides enhanced visualization and access for glomus tympanicum resection.
• This technique facilitates safe, rapid, and reliable tumor removal.
• The endoscopic approach enhances surgical comfort for both the patient and the surgeon.
