“…Total resection of the tumor was obtained in all studies presented, apart from three patients in the series of Fermi, et al [14], because the tumors were closely related to the carotid artery. As for the complications, the most common one was tympanic membrane perforation in five patients [2,4,10,14,15], dysgeusia in four just from the series of Fermi, et al [14], and hearing loss in one patient [5]. In our three cases, no major complications were recorded.…”

“…The most common methods, used for coagulation were bipolar cautery [4,5,13,14] and lasers. Argon plasma coagulation (APC) [13], diode [1], CO 2 [1,[3][4][5]15], and potassium titanyl phosphate (KTP) [1,2] lasers have all been used to achieve hemostasis. In two of our cases, a type of monopolar coagulation was used, by leaning the monopolar diathermy tip against a suction catheter.…”

Glomus tympanicum are benign tumors of vascular origin, arising from the neural crest cells and located on promontory. The treatment of choice is surgical excision of the lesion. Traditionally, it is performed under microscopic observation. With the introduction of endoscopes in the field of ear surgeries, an endoscopic approach has also evolved. Herein, we present case reports of three patients diagnosed with glomus tympanicum tumors who were operated on using an endoscopic approach. A review of the literature is also performed. The mass was completely excised in all patients, and there were no signs of recurrence at the follow-up at least a year later. Endoscopic ear surgery is a safe and effective method of managing glomus tympanicum tumors. Its main limitation is the tumor size; however, in most cases, tumors of stages I to II as per the Glasscock-Jackson classification and types A1 to B1 according to the modified Fisch-Mattox classification can be completely removed endoscopically. Careful preoperative selection of patients warrants the best outcomes.
