Acute otitis externa: Consensus definition, diagnostic criteria and core outcome set development.

PLoS One 2021 14;16(5):e0251395. Epub 2021 May 14.

Salford Royal Hospital, Salford, United Kingdom.

Objective: Evidence for the management of acute otitis externa (AOE) is limited, with unclear diagnostic criteria and variably reported outcome measures that may not reflect key stakeholder priorities. We aimed to develop 1) a definition, 2) diagnostic criteria and 3) a core outcome set (COS) for AOE.

Study Design: COS development according to Core Outcome Measures in Effectiveness Trials (COMET) methodology and parallel consensus selection of diagnostic criteria/definition. Read More

Examining the utility of nuclear medicine imaging in the diagnosis and management of necrotising otitis externa.

Clin Otolaryngol 2021 May 9. Epub 2021 May 9.

Consultant Otologist, Portsmouth Hospitals University NHS Trust, Queen Alexandra Hospital, Southwick Hill Road, Cosham, Hampshire, PO6 3LY, UK.

The primary objective of this study was to assess whether combination modality imaging (CT, and/or Technetium/Gallium) had any additional benefits over single modality imaging (CT) in the diagnosis and management of NOE. Combination modality imaging, in patients with a negative CT but raised clinical suspicion of NOE, did infer additional benefit over single modality imaging using CT. Gallium scanning, used to determine treatment end, was poorly representative of residual disease presence, with clinical assessment favoured instead. Read More

Dysphagia due to necrotizing otitis externa.

Age Ageing 2021 May;50(3):1004-1005

University of Nottingham School of Health Sciences, Nottingham, UK.

An 88-year-old man presented with delirium, and subsequently developed hoarseness and oropharyngeal dysphagia. This was due to skull-based osteomyelitis from necrotizing otitis externa (NOE), causing lower cranial nerve (X, XII) palsies and venous sinus thrombosis. Diagnosis was delayed as the patient reported no otalgia, had an almost normal looking external auditory canal and was not diabetic. Read More

A Systematic Review of Antibiotic Prescription for Acute Otitis Externa.

Cureus 2021 Mar 27;13(3):e14149. Epub 2021 Mar 27.

Otolaryngology, Warwick Hospital, Warwick, GBR.

Background: There is a perception among ear, nose, and throat (ENT) surgeons that oral antibiotics are over-prescribed for acute otitis externa (AOE), and the potential for topical therapy as first-line treatment is not fully realized in primary care. We evaluated the prescription rate of topical and oral antibiotics for AOE in primary care and in patients referred to the ENT emergency clinic.

Methods: A systematic review was performed by searching the MEDLINE, Embase, PubMed, and Google Scholar databases between January 1990 and October 2020. Read More

Direct Detection and Identification of the Most Common Bacteria and Fungi Causing Otitis Externa by a Stepwise Multiplex PCR.

Front Cell Infect Microbiol 2021 25;11:644060. Epub 2021 Mar 25.

Department of Medical Parasitology and Mycology, School of Medicine, Isfahan University of Medical Sciences, Isfahan, Iran.

Background: Considering the importance of differential diagnosis of infectious otitis externa (OE), a stepwise PCR-based assay using universal and genus- or species-specific primers for the detection/identification of the most prevalent bacterial and fungal OE was developed and evaluated on the ear aspiration specimens of clinically suspected patients.

Methods And Materials: A total of 120 ear aspiration specimens with otomycosis suspicion were subjected to manual DNA extraction using phenol-chloroform extraction after tissue digestion with a lysis buffer. The multiplex PCR was initially performed using pan-fungal and bacterial homemade primers. Read More

Management of tympanic membrane retractions: a systematic review.

Eur Arch Otorhinolaryngol 2021 Mar 10. Epub 2021 Mar 10.

Department of Otolaryngology-Head and Neck Surgery, University Medical Centre Utrecht, Utrecht, The Netherlands.

Importance: Tympanic membrane retraction (TMR) is a relatively common otological finding. However, no consensus on its management exists. We are looking especially for a treatment strategy in the military population who are unable to attend frequent follow-up visits, and who experience relatively more barotrauma at great heights and depths and easily suffer from otitis externa from less hygienic circumstances.
