BACKGROUND AND OBJECTIVES Methicillin-resistant Staphylococcus aureus (MRSA) is one of major pathogens in patients with chronic suppurative otitis media (CSOM). In addition to intrinsic MRSA infection of the mastoid air cell system, nasal colonization of MRSA, a known predictor of postoperative surgical site infection, may pose increased risk of postoperative complications. The purpose of this ...

INTRODUCTION Although several anatomical anomalies in the middle turbinate have been reported, they usually remain asymptomatic. However, complicated aberrant middle turbinate extending through the choana to the contralateral nasopharynx has not been reported. CASE PRESENTATION A 23-year-old Korean woman presented with a 6-month history of nasal obstruction and postnasal discharge refractory ...

OBJECTIVE To report a rare case of unilateral cavernous sinus thrombosis caused by contralateral sphenoid sinusitis. CASE REPORT A 33-year-old female visited our hospital for severe, right-sided, temporal headache, chemosis, periorbital edema, and proptosis. These signs were associated with congested erythematous nasal mucosa with purulent discharge from the right superior nasal meatus. Contr...

The VIIth cranial (facial) nerve is largely motor in function (some sensory fibres from external acoustic meatus, fibres controlling salivation and taste fibres from the anterior tongue in the chorda tympani branch). It also supplies the stapedius (so a complete nerve lesion will alter auditory acuity on the affected side). From the facial nerve nucleus in the brainstem, fibres loop around the ...

OBJECTIVES To evaluate the accuracy of acoustic rhinometry (AR) measurements, and to assess how well AR detects obstructions of various sizes at specific sites in the nasal cavity, we created a cast model from an adult cadaver nasal cavity. METHODS The actual cross-sectional areas of the cast model nasal passage were determined by computed tomography and compared with the corresponding areas ...

A 70-year-old man with a history of chronic middle and external ear suppuration presenting with acute meningitis due to Bacteroides uniformis is described. Anaerobic organisms including Bacteroides species were cultured from the affected external auditory meatus. Administration of metronidazole led to complete clinical recovery and a cholesteatoma was subsequently surgically evacuated. Chronic ...

The Late Pleistocene Shanidar 1 older adult male Neandertal is known for the crushing fracture of his left orbit with a probable reduction in vision, the loss of his right forearm and hand, and evidence of an abnormal gait, as well as probable diffuse idiopathic skeletal hyperostosis. He also exhibits advanced external auditory exostoses in his left auditory meatus and larger ones with complete...
