Understanding the nature of the biofilm component in the pathogenesis of otitis media [OM] will likely have a meaningful influence on the development of novel strategies to prevent and/or treat this highly prevalent pediatric disease. The design of vaccine candidates for OM that currently focus on preventing colonization are predicated on the assumption that by reducing the burden of bacteria present in the pediatric nasopharynx, one could reduce or eliminate the likelihood of retrograde ascension of the Eustachian tube by bacteria from the nasopharynx to the middle ear. If effective, this strategy could prevent biofilms from ever forming in the middle ear. Additionally, gaining an improved understanding of the unique properties of bacteria resident within a biofilm and the proteins they express while growing as part of this organized community has the potential to identify novel and perhaps biofilm-specific molecular targets for the design of either therapeutic agents or vaccine candidates for the resolution of existing OM.

Objective: Eosinophilic Otitis Media (EOM) is an intractable disease caused by type 2 inflammation, such as Eosinophilic Chronic Rhinosinusitis (ECRS) and bronchial asthma. Biologics have recently been used to treat ECRS and bronchial asthma. Biologics are not indicated for EOM; however, because approximately 10% of ECRS cases has concomitant EOM, concomitant EOM improvement has been observed when dupilumab is administered for ECRS.

Objectives: The aim of this study was to investigate the risk factors that may cause postoperative otomycosis in patients undergoing Chronic Nonsuppurative Otitis Media (CNSOM) surgery.
Methods: In this retrospective study, 409 out of 523 patients met the inclusion criteria. 44 patients diagnosed with otomycosis CNSOM were analyzed.

Purpose: Cost-utility analyses examining the value of new vaccines for pneumococcal disease will require health state utilities as inputs. Existing utilities for pneumococcal infections in young children are limited. The purpose of this study was to estimate health state utilities associated with pneumococcal infections in young children.

Background: Canine aural cholesteatoma (more appropriately named tympanokeratoma) is an epidermoid cyst whose aetiopathogenesis remains poorly recognised in veterinary medicine. There are a few reports published, possibly because it may be underdiagnosed.
Objectives: To characterise the clinical aspects of dogs with tympanokeratoma, to describe the otoendoscopic, advanced imaging and histopathological findings of tympanokeratoma and to report the best approach to diagnose canine auricular tympanokeratoma in a retrospective study.

The authors describe a rare case of non-Hodgkin lymphoma (NHL) with primary involvement of the external auditory canal (EAC) and subsequent dissemination to the central nervous system, initially manifesting as a benign ear infection. This case highlights the importance of considering differential diagnoses in patients with persistent or worsening symptoms unresponsive to empirical treatment. A 53-year-old man presented with a one-week history of aural fullness, otalgia, and otorrhea in the left ear.
