Empirical antibiotics constitute the cornerstone of medical therapy for chronic sinusitis due to difficulties of obtaining cultures from the paranasal sinuses. Indirect isolation of the pathogenic microorganisms outside the paranasal sinuses with a non-invasive method may enable administration of specific antibiotics. In this prospective study, we obtained cultures from the middle meatus and et...

Paranasal sinus mucoceles are benign cystic lesions, filled with mucus, occurring due to an obstruction of involved sinus ostium. They are indolent, locally expansive, and destructive. Surgical treatment must be performed and, when done at the correct time, may prevent sequelae. We present a case of ethmoid sinus mucocele with orbit involvement and permanent optical nerve injury.

ectopic eruption of teeth occurs in a variety of locations. commonly seen in palate and maxillary sinus, they have also been reported in nasal cavity, orbit, mandibular condyle, coronoid process, and facial skin. here, we report a rare case of recurrent sinusitis caused by ectopic tooth in right ethmoid sinus and successful endoscopic removal of it. the symptoms of the patient disappeared after...

BACKGROUND Maxillary sinus mucoceles are relatively rare among all paranasal sinus mucoceles. With the introduction of endoscopic sinus surgical techniques, rhinologic surgeons prefer transnasal endoscopic management of sinus mucoceles. The aim of this study is to describe the clinical presentation of maxillary sinus mucoceles and to establish the efficacy of endoscopic management of sinus muco...
