Orbital tumor surgery (orbitotomy) is a microsurgical procedure to remove orbital masses, eliminating the pathological focus while preserving visual function. Guided by advanced imaging techniques, the ophthalmic surgeon selects the optimal approach to access the tumor. Using microsurgical instruments and an operating microscope, the growth is removed with minimal trauma to surrounding tissues. The surgery is recommended for benign and malignant orbital tumors, cysts, and inflammatory pseudotumors. As a result, pressure on the optic nerve and eyeball is relieved, eye mobility is restored, and the patient quickly returns to normal daily activities.
