Bone resorption is an important aspect of chronic otitis media contributing to many complications of this disease. It is postulated that the mechanism of this localized destructive process is chemical in origin. Collagenase, lysosomal enzymes, prostaglandins, and other cell mediators are thought to induce bone resorption, but the site of action and cellular origin of these substances remains un...

Otitis media with effusion (OME), also called glue ear, is characterised by a collection of fluid in the middle-ear cleft. there is chronic inflammation but without signs of acute inflammation. OME is the most common cause of hearing impairment (and the most common reason for elective surgery) in childhood, where it usually follows an episode of acute otitis media (AOM). It is uncommon in adult...

OBJECTIVE To explore the association between chronic suppurative otitis media and sensorineural hearing loss. METHOD The files of 147 patients with unilateral chronic suppurative media were reviewed in a retrospective study. Differences between diseased and control ear bone conduction thresholds were analysed by the paired student's t-test over the four frequencies (0.5 kHz, 1.0 kHz, 2.0 kHz,...

BACKGROUND Recently, demand for and supply of short-form patient-reported outcome measures (PROMs) have risen throughout the world healthcare. Our contribution to meeting that demand has been translating and culturally adapting the Chronic Otitis Media Questionnaire-12 (COMQ-12) for adults into Serbian and enhancing its psychometric base on the relatively large Serbian COM caseload. Chronic oti...

INTRODUCTION Tuberculous otitis is a diagnostic problem due to the difficulty to obtain microbiological, histomorphological and cytological confirmation of the disease. OBJECTIVE Our objective was to compare clinical and radiological characteristic and development of otogenic complications in patients with tuberculous otitis and otitis with cholesteatoma as the most destructive form of chroni...

The objective of the present work was to study the characteristics of middle ear microflora in the patients presenting with chronic suppurative otitis media (CSOM), clarify changes in its species composition over the territory of the Transbaikal Krai during the period from 2000 till 2013, and elucidate its dependence on the treatment prescribed with due regard for sensitivity of microorganisms ...

INTRODUCTION Citelli's abscess is an extratemporal complication of otitis media. It occurs when pus from the mastoid tip trickles down along the posterior belly of the digastric muscle to the occipital and cervical region. It is a very unusual presenting complication of chronic otitis media with no available data in the until now. CASE REPORT A 10-year-old female was presented to our outpatie...

Even though there are other complications of chronic suppurative otitis media, the aspect of hearing loss is often studied. Nevertheless, the occurrence of sensorineural hearing loss in patients with this disease is still controversial. This study aim (1) to assess the association between sensorineural hearing loss and chronic suppurative otitis media, (2) to investigate some clinical factors t...

Nonencapsulated, nontypeable Hemophilus influenzae (NTHi) remains an important cause of acute otitis and respiratory diseases in children and adults. NTHi bacteria are one of the major causes of respiratory tract infections, including acute otitis media, cystic fibrosis, and community-acquired pneumonia among children, especially in developing countries. The bacteria can also cause chronic dise...

Tympanic membrane (TM) perforation, in particular chronic otitis media, is one of the most common clinical problems in the world and can present with sensorineural healing loss. Here, we explored an approach for TM regeneration where the latent progenitor or stem cells within TM epithelial layers may play an important regulatory role. We showed that potential TM stem cells present highly positi...
