Experience in surgical treatment of large osteomas of the paranasal sinuses

Osteomas are benign neoplasms affecting both tubular and flat bones of the body. When the paranasal sinuses are affected, their most frequent localization is the frontal sinus. The growth of osteomas is extremely slow, but when it reaches a significant size, the tumor destroys the walls of the paranasal sinuses and affects nearby structures, which can lead to severe intraocular and intracranial complications. The only method of treating osteomas of the paranasal sinuses is surgical. There are several surgical approaches to remove them. There is no single approach for choosing the method of surgical removal of osteomas of the paranasal sinuses. The article describes our experience in treating 7 patients with different localization and sizes of osteomas of the paranasal sinuses. The factors influencing the choice of one or another access during surgical removal of the tumor are described.
A clinical case. The article also presents a clinical observation of a large (22х31х38 mm) osteomas of the frontal sinus, spreading to the cells of the lattice labyrinth, lobbing into the orbit and pushing the eyeball laterally. A 19-year- old patient turned to the ENT clinic of the M. F. Vladimirsky State Medical University of the Ministry of Health of the Russian Federation with complaints of a cosmetic defect. The removal of a large osteoma of the frontoethmoid area was performed using open access through an incision along the eyebrow with a continuation to the slope of the nose, with the reconstruction of the lost walls of the paranasal sinuses with titanium platinum. A good functional and cosmetic result has been achieved.
