Menzies School of Health Research, Charles Darwin University, Darwin, NT, Australia.

Introduction: Otitis media (OM) is a common childhood illness, often resolving without intervention and acute and long-term complications are rare. However, Australian Aboriginal and Torres Strait Islander infants and children experience a high burden of OM and are at high risk of complications (tympanic membrane perforation and chronic infections). Bacterial OM is commonly associated with , non-typeable , and . Read More

Otitis externa (OE) is a condition that involves inflammation of the external ear canal. OE is a commonly reported condition in humans and some veterinary species (for example, dogs, cats), but has not been reported in the literature in macaques. Here, we present a case series of acute and chronic OE likely precipitated by abrasion of the ear canal with a tympanic membrane electrode in 7 adult male rhesus macaques (). Read More

Laboratory for Biomaterials and Drug Delivery, The Department of Anesthesiology, Critical Care and Pain Medicine, Boston Children's Hospital, Harvard Medical School, Boston, Massachusetts 02115, United States.

Localized and non-invasive delivery of therapeutics across barriers in the body is challenging. Examples include the flux of drugs across the tympanic membrane (TM) for the treatment of middle ear infections, and across the round window to treat inner ear disease. With the emergence of macromolecular therapies, the question arises as to whether such delivery can be achieved with macromolecules. Read More

Innate Immunity in the Middle Ear Mucosa.

Front Cell Infect Microbiol 2021 29;11:764772. Epub 2021 Oct 29.

Menzies Health Institute Queensland, School of Medicine, Griffith University, Gold Coast, QLD, Australia.

Otitis media (OM) encompasses a spectrum of clinical presentations ranging from the readily identifiable Acute OM (AOM), which is characterised by otalgia and fever, to chronic otitis media with effusion (COME) where impaired hearing due to middle ear effusion may be the only clinical symptom. Chronic suppurative OM (CSOM) presents as a more severe form of OM, involving perforation of the tympanic membrane. The pathogenesis of OM in these varied clinical presentations is unclear but activation of the innate inflammatory responses to viral and/or bacterial infection of the upper respiratory tract performs an integral role.

Eur Ann Otorhinolaryngol Head Neck Dis 2021 Dec 7;138(6):467-469. Epub 2021 Jul 7.

Department of Otorhinolaryngology, School of Medicine and Pharmacy, Vietnam National University, 144 Xuan Thuy Street, Hanoi City, Viet Nam.

Indian J Otolaryngol Head Neck Surg 2021 Jun 30:1-8. Epub 2021 Jun 30.

Department of ENT and HNS, SRN Hospital, Prayagraj, Uttar Pradesh India.

The tympanic membrane (TM) undergoes a number of pathological changes in middle ear disease which can be detected by a video-otoendoscope. Middle ear disease is also accompanied by changes in middle ear pressure which can be assessed by tympanometry. The objectives of this study were to find the correlation between video-otoendoscopy and tympanometry in acute middle ear infections and to deduce which of the two is more efficient and reliable for early diagnosis.

Topical versus systemic antibiotics for chronic suppurative otitis media.

Cochrane Database Syst Rev 2021 02 9;2:CD013053. Epub 2021 Feb 9.

Telethon Kids Institute, The University of Western Australia, Perth, Australia.

Background: Chronic suppurative otitis media (CSOM), sometimes referred to as chronic otitis media (COM), is a chronic inflammation and often polymicrobial infection (involving more than one micro-organism) of the middle ear and mastoid cavity, characterised by ear discharge (otorrhoea) through a perforated tympanic membrane. The predominant symptoms of CSOM are ear discharge and hearing loss. Antibiotics are the most common treatment for CSOM, which act to kill or inhibit the growth of micro-organisms that may be responsible for the infection. Read More

In vivo dynamic characterization of the human tympanic membrane using pneumatic optical coherence tomography.

J Biophotonics 2021 04 18;14(4):e202000215. Epub 2020 Aug 18.

Department of Bioengineering, University of Illinois at Urbana-Champaign, Urbana, Illinois, USA.

Decreased mobility of the human eardrum, the tympanic membrane (TM), is an essential indicator of a prevalent middle ear infection. The current diagnostic method to assess TM mobility is via pneumatic otoscopy, which provides subjective and qualitative information of subtle motion. In this study, a handheld spectral-domain pneumatic optical coherence tomography system was developed to simultaneously measure the displacement of the TM, air pressure inputs applied to a sealed ear canal, and to perform digital pneumatic otoscopy.
