Chronic ethmoiditis

Chronic ethmoiditis proceeds mainly as a catarrhal inflammatory process. Around the outlet openings of the trellised cells, thickenings of the mucous membrane are formed, which are small, multiple polyps. Patients complain of pressing pain in the nose or inner corner of the orbit. Smell reduced. With rhinoscopy, pus is found under the middle shell (damage to the anterior ethmoid cells) or above it (damage to the posterior ethmoid cells). Often, pus is secreted after removal of the polyps. To clarify the diagnosis, data from an x-ray study.

Treatment in acute cases is conservative, as with inflammation of other sinuses. In uncomplicated forms of chronic ethmoiditis, treatment is also conservative. Sometimes such intranasal surgical interventions as removal of the anterior end of the middle shell or polypotomy are used. In advanced cases, an intranasal or external dissection of the cells of the ethmoid labyrinth is performed.
