Diagnostic criteria and core outcome set development for necrotising otitis externa: the COSNOE Delphi consensus study.

Objective: Evidence for necrotising otitis externa (NOE) diagnosis and management is limited, and outcome reporting is heterogeneous. International best practice guidelines were used to develop consensus diagnostic criteria and a core outcome set (COS).

Methods: The study was pre-registered on the Core Outcome Measures in Effectiveness Trials (COMET) database.

Cartilage grafts mimicking cholesteatoma recurrence on diffusion-weighted magnetic resonance imaging: a case series.

Background: Cholesteatomas present a high risk for residual and recurrent disease, and the surveillance of post-operative patients can be challenging. Diffusion-weighted magnetic resonance imaging is becoming the preferred method for investigating recidivism; however, false positive imaging findings increase the risk of patients undergoing unnecessary second look surgery.

Case Reports: This study reports two patients with false positive diffusion restriction associated with cartilage grafts that mimicked cholesteatoma and resulted in second look surgery with no disease found at operation.

The diagnostic yield of head and neck imaging in symptomatic patients with a normal clinical examination.

Aim: Nationally, concern has been raised about the overuse of diagnostic testing. In patients with unilateral otalgia and no history of Head and Neck Cancer (HNC), 1% had a malignancy detected on imaging that was not detected on clinical examination.

Methods: We performed a retrospective review of "MRI soft tissue neck" scans performed at our hospital from May 2020 to May 2021.

Silicone granuloma: a cause of cervical lymphadenopathy following breast implantation.

We report a case of a 54-year-old woman with saline-based breast implants who presented to the ear, nose and throat neck lump clinic with a 2-week history of bilateral neck lumps. She was found to have multiple palpable cervical lymph nodes bilaterally in levels IV and Vb. The ultrasonography demonstrated multiple lymph nodes with the snowstorm sign and a core biopsy confirmed a silicone granuloma (siliconoma).

Imaging features of non-epithelial tumours of the larynx.

Neoplasms of the head and neck most commonly seen within the larynx are likely malignant and epithelial in origin. Although uncommon, non-epithelial types are occasionally encountered in clinical practice. Owing to the rare nature of these entities, they can lead to diagnostic and treatment uncertainty.
