We herein report four operative cases of temporal bone glomus tumors encountered between 2016 and 2021. Two of the cases were glomus jugulare, and the other two were glomus tympanicum. Characteristic symptoms included pulsatile tinnitus in the two patients with glomus tympanicum. Preoperative audiometry revealed conductive hearing loss on the affected side and air-bone gap in three patients. One of the glomus jugulare cases required three surgeries: a biopsy, resection, and reoperation. Vascular embolization was performed in all four cases. There was no evidence of pre- or postoperative neurologic deficit in any cases. No postoperative recurrence or regrowth was observed in any cases, and the patients are under follow-up. Because glomus tumors are rich in blood vessels, preoperative embolization and the use of a high-frequency bipolar coagulator may aid in performing safe surgery.
