Glomus jugulare tumors treatment by gamma knife radiosurgery: A single center study.

Objective: Glomus jugulare tumor are benign vascular tumors and surgical resection is almost impossible. We have treated these tumors by Gamma knife radiosurgery and share our experience. Methods: This study was conducted at the Neurospinal and Cancer Care Institute, Karachi from January 2010 to May 2020. Thirty-four patients with glomus jugulare tumors treated with gamma knife radiosurgery were included in the study. The comprehensive clinical and demographic characteristics of all patients were collected through a manually designed questionnaire. Computed tomography, digital subtraction angiography and magnetic resonance imaging were used to make the diagnosis. Data was incorporated and analyzed by SPSS version 26. Results: A total of 34 patients were included in the study of which 16(47%) were males and 18(53%) were females with first follow up after 6-month up to two year clinical and radiological follow-up. The mean age of the patients was 42.5±13.5 with a minimum age of 20 years and maximum age of 65 years. The KPS scale was 2.09±0.45 and the volume of the tumor was 33.8±22.5 cm Conclusions: Gamma Knife radiosurgery is a safe and effective primary therapy and salvage therapy for residual and recurrent cases of glomus jugulare and tympanicum tumors.
