[Digital volume tomography in the diagnosis of the surgical anatomy of the frontal recess area].

Frontal recess anatomy can be very complex, with accessory cells, such as frontal bulla, agger nasi, suprabulla, and frontal ethmoidal (Kuhn) cells, which may lead to obstruction of the frontal sinus. Digital volume tomography of paranasal sinuses used in this investigation revealed the rate of types of development of various anatomic structures and their correlation with frontal sinusitis in patients with (a study) and without the latter (a control group).
