Asymmetry of the Middle Turbinates and Ethmoid Sinuses

Variant anatomy of nasal turbinates: supreme, superior and middle conchae bullosae, paradoxical superior and inferior turbinates, and middle accessory turbinate.

Multiple anatomical variants were encountered during a cone beam computed tomography (CBCT) study of the nasal cavity of a 43-year-old male patient. These were mostly related to the nasal turbinates, suggestive for an unusual development of ethmoturbinals. Pneumatized turbinates were observed: bilateral supreme, superior, and middle concha bullosa. There were bilateral paradoxically curved supe...

Giant osteomas of the ethmoid and frontal sinuses: Clinical characteristics and review of the literature

Giant osteomas of the ethmoid and frontal sinuses ary very rare, with only a few dozen cases reported in the literature. Given their rarity, the clinical characteristics and treatment of this disease remain controversial. In this study, the clinical presentation and surgical methods used to treat three patients with giant osteomas of the ethmoid and frontal sinuses are described, combined with ...

Combined Aplasia of Sphenoid, Frontal, and Maxillary Sinuses With Hypoplasia of The Ethmoid Sinus

which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Paranasal sinuses are prone to a great diversity of anomalies. Aplasia of the frontal sinus is a relatively common phenomenon and may be accompanied with hypoplasia of the maxillary sinus, but combined aplasia or underde-velopment of the paranasal sinuses is unusual (1, 2)...

Inflammation and remodelling patterns in early stage chronic rhinosinusitis.

BACKGROUND A distinct set of inflammatory and remodelling factors have been found elevated in chronic rhinosinusitis. OBJECTIVE The investigation of their expression in early stage disease may reveal early events in this common disease. METHODS Sinonasal mucosal samples from nine patients with early stage CRSsNP were taken from the inferior and middle turbinates, the uncinate process, maxil...
