BACKGROUND Sinus mucosa abnormalities on image studies, which is the major diagnostic measure for sinusitis, were investigated in patients with nasopharyngeal carcinoma (NPC) after intensity-modulated radiotherapy (IMRT). METHODS A retrospective review of the MRIs for patients with NPC was conducted. Sinus mucosa abnormalities were staged by the Lund-Mackay system. RESULTS A total of 94 pat...

INTRODUCTION Congenital choanal atresia is a relatively rare deformity, especially bilateral congenital choanal atresia. We report a case of bilateral congenital choanal atresia in a 22-year-old Chinese man, who was also diagnosed with congenital right accessory nasal deformity, osteoma of his left ethmoid sinus and congenital keratoleukoma of his right eye. CASE PRESENTATION A 22-year-old Ch...

A case of giant ethmoid osteoma treated by functional endoscopic sinus surgery is described. The tumour was closely adherent to the surrounding anatomical structures--lamina papyracea, cribriform plate, spheno-ethmoidal recess--and protruded into the nasopharynx. Complete removal of the tumour, under general anaesthesia, using intranasal drill and diode L.A.S.E.R, was achieved. The principal as...

Disorders of the paranasal sinuses, particularly the sphenoid sinus, can be associated with significant disorders of the optic and other cranial nerves. We examined 100 consecutive routine CT scans, 100 posterior fossa CT scans, and 100 MR scans to look for evidence of sinus disease, especially of the sphenoid sinus. The sphenoid sinus was abnormal in 7% of scans by all methods. Other sinuses w...

Orbital emphysema is generally recognized as a complication of orbital fractures involving any paranasal sinuses. The recognition about its etiology has extended beyond sole trauma, but few articles mentioned tumors to be a possible cause.In this case report, we present a patient with orbital emphysema associated with ethmoid osteoma without orbital cellulitis or trauma history. The patient dev...

BACKGROUND Epistaxis is a common otolaryngology emergency and is often controlled with first-line interventions such as cautery, hemostatic agents, or anterior nasal packing. A subset of patients will continue to bleed and require more aggressive therapy. METHODS Intractable spontaneous epistaxis was traditionally managed with posterior nasal packing and prolonged hospital admission. In an ef...

As endoscopic sinus surgery has been used widely in sinus pathologies and advancements in computerized tomography technologies, the importance of the lateral nasal wall anatomy and its variations has been emphasized more commonly. In evaluation of endoscopic and radiological anatomy of paranasal sinuses attention must be paid to these variations. Concha bullosa which is an anatomical variation ...
