We describe a patient with nasopharyngeal lymphoma who was admitted for chemotherapy. At admission, otoscopic examination revealed a large polyp occluding the left external ear canal. The polyp was removed, and histopathologic examination showed the same tumor that was found previously in the nasopharynx. Magnetic resonance imaging showed an infiltrative process that involved the left side of the nasopharynx and extended toward the left middle and external ear. To our knowledge, this is the first case report of a direct extension of nasopharyngeal lymphoma into the middle and external ear.

Introduction: The tympanic cavity contains three tiny bones, the malleus, incus, and stapes, which have a fundamental role in the transmission of sound. Recent research emphasizes the use of CBCT for the anatomic study of the temporal bone. The information about middle ear anatomy on CBCT scans is meager; hence, this retrospective study was conducted to identify and determine the various morphometrical parameters of the malleus using CBCT which can be helpful during reconstructive procedures for the otologic surgeon.

Objective: To evaluate the diagnostic potential of spontaneous otoacoustic emissions (SOAE), distortion product otoacoustic emissions (DPOAE), and pure-tone audiometry (PTA) in patients with pulsatile tinnitus (PT) caused by sigmoid sinus wall anomalies (SSWA).
Methods: This study included 20 PT patients and 20 matched healthy controls. SOAE, DPOAE, and PTA were assessed before and after compression of the internal jugular vein.

Background: Subjective tinnitus is characterized by perception of sound in the absence of any external or internal acoustic stimuli. Many approaches have been developed over the years to treat tinnitus (medical and nonmedical). However, no consensus has been reached on the optimal therapeutic approach.

Infections by non-O1/non-O139 serogroups of Vibrio cholerae (NOVC) are increasing worldwide. Infected patients usually display self-limiting diarrhoea or external ear and wound infections. We present a rare case of bacteraemia secondary to NOVC infection.

Unlabelled: The concept of genome-microbiome interactions, in which the microenvironment determined by host genetic polymorphisms regulates the local microbiota, is important in the pathogenesis of human disease. In otolaryngology, the resident bacterial microbiota is reportedly altered in non-infectious ear diseases, such as otitis media pearls and exudative otitis media. We hypothesized that a single-nucleotide polymorphism in the ATP-binding cassette sub-family C member 11 () gene, which determines earwax properties, regulates the ear canal microbiota.
