Objectives: Anecdotal evidence suggests that oropharyngeal squamous cell carcinoma (OPSCC) should be suspected in patients presenting with symptoms of peritonsillar abscess (PTA) or cellulitis (PTC). The aim of this study was to estimate the prevalence of OPSCC in patients presenting with symptoms of PTA/PTC.

Method, Setting And Participants: We retrospectively identified all adults with a coded diagnosis of PTA or PTC who presented between 2012 and 2016 inclusive, across six ENT units in Merseyside.

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.

Globus is the sensation of a foreign body in the throat. Investigation and management of patients with globus is widely variable. Most investigations yield negative results yet incur varying patient morbidity and healthcare costs, while malignancy is vanishingly rare in the absence of red flag symptoms and ear, nose and throat examination findings.

We present an unusual case of spontaneous cervical haemorrhage secondary to extra-capsular bleeding from a parathyroid adenoma. Signs and symptoms on presentation included sore throat, dysphagia and anterior chest ecchymosis. While CT confirmed active cervical haemorrhage, elevated serum calcium and parathyroid hormone raised suspicion of possible parathyroid pathology.

Purpose: Seroma/sialocele and haematoma formations following parotidectomy are common complications. Fibrin-sealant tissue glue (FSTG) applied to the surgical bed prior to closure has been used widely to reduce such complications at other surgical sites. We sought to evaluate a potential role in parotidectomy, examining outcomes before and after the use of FSTG was introduced in our department.

Background: Objective acoustic analysis is a key component of multidimensional voice assessment. OperaVOX is an iOS app which has been shown to be comparable to Multi Dimensional Voice Program for most principal measures of vocal function. As a relatively cheap, portable and easily accessible form of acoustic analysis, OperaVOX may be more clinically useful than laboratory-based software in many situations.

This study aimed to report the bone-anchored hearing aid uptake rate and the reasons for their rejection by patients with conductive and mixed hearing losses. A retrospective review was performed of 113 consecutive patients with unilateral or bilateral conductive or mixed hearing loss referred to the Greater Manchester bone-anchored hearing aid (BAHA) programme between September 2008 and August 2011. 98 (86.
