OBJECTIVE To evaluate the use of sinoscopy for detection and treatment of ventral conchal sinus (VCS) and/or rostral maxillary sinus (RMS) disease in horses. STUDY DESIGN Case series ANIMALS Horses (n=60) with suspected paranasal sinus disease. METHODS Horses were evaluated by sinoscopy through a conchofrontal sinus (CFS) portal with ventral conchal bulla (VCB) fenestration. Other endosco...

purpose: to report a patient with exotropia due to medial rectus muscle entrapment as a complication of endoscopic dacryocystorhinostomy (edcr). case report: a 34-year-old female was referred with left exotropia 18 days after edcr for treatment of primary nasolacrimal duct obstruction. she had a large angle left exotropia in primary position as well as complete limitation of adduction and parti...

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)...

This study aims to determine the relationship between nasal septal deviation, concha bullosa, and chronic rhinosinusitis by using a definitive pathological and simplified model. Fifty-two consecutive sinus computed tomography scans were performed on patients who received endoscopic sinus surgery and whose final diagnosis was paranasal sinus fungus balls. The incidences of nasal septal deviation...

Craniofacial osteomas may be located either superficially or intraosseously on any bone of the cranium or face or within a paranasal sinus. Osteomas within the paranasal sinus account for 0.01% to 0.43% of patients; of these, up to 80% occur in the frontal sinus. An osteoma of maxillary sinus is extremely rare. We describe a rare case of osteoma of a 56-year-old Asian woman in the maxillary sinus.

Nasopharyngeal carcinoma (NPC) may spread to the paranasal sinuses. This retrospective study describes the features of paranasal sinus involvement in NPC on computed tomography (CT) and magnetic resonance imaging (MRI). One hundred and fourteen patients with histologically proven NPC underwent staging with both CT and MRI. Maxillary sinus infiltration was demonstrated on MRI in 10 patients; sph...

BACKGROUND AND PURPOSE The incidence of middle turbinate pneumatization, or concha bullosa, has been well described in the literature. However, to our knowledge, no study has evaluated concha bullosa in relation to nasal septal deviation. We sought to analyze the incidence of concha bullosa and any correlation with nasal septal deviation and paranasal sinus disease. METHODS Three neuroradiolo...
