Cutaneous squamous cell carcinoma (SCC) of the head and neck may metastasize in up to 5% of patients, with the parotid lymph nodes the most frequent site for spread. Metastases frequently show delayed presentation after the primary cancer had been treated. The optimum treatment should be surgery followed by adjuvant radiotherapy, with an appropriate parotidectomy, and preservation of the facial nerve if not involved by tumor and treatment to the neck. In a clinically N0 neck, levels I to III should be cleared for facial primaries, levels II to III for anterior scalp and external ear primaries, and levels II to V for posterior scalp primaries. Approximate 5‐year disease‐specific survival (DSS) after treatment was 70% to 75%. Patients with immunosuppression, in particular transplant recipients, are at high risk of developing aggressive metastatic cutaneous SCC. Modifications of the staging systems have demonstrated the prognostic benefits of accurately staging parotid and/or neck nodal disease.

Objectives: Mucosal changes in the paranasal sinuses are detected in 30–50% of scans for non‐rhinological disease. This study assesses the relationship between symptoms of rhinosinusitis and radiological evidence of sinus pathology in patients undergoing magnetic resonance imaging (MRI) scans for unrelated pathology.

Trans‐oral surgical and non‐surgical management options for oropharyngeal squamous cell carcinoma (OPSCC) appear to offer similar survival outcomes. Functional outcomes, in particular swallowing, have become of increasing interest in the debate regarding treatment options. Contemporary reviews on function following treatment frequently include surrogate markers and limit the value of comparative analysis.

BACKGROUND Oropharyngeal cancer is increasing in prevalence in the UK and this is thought to be due to the emergence of disease related to human papilloma virus. METHOD A literature review was conducted on the diagnosis and latest management of oropharyngeal cancer. RESULTS In non-smokers, human papilloma virus related disease is thought to have better outcomes, but this casts doubt on previous research which did not stratify patients according to human papilloma virus status. However, this theory provides a route for researchers to risk stratify and de-escalate treatments, and hence reduce treatment burden. In addition, the emergence of minimally invasive transoral techniques allows surgeons to remove large tumours without many of the side effects associated with radical (chemo)radiotherapy. CONCLUSION The emergence of human papilloma virus related disease and minimally invasive techniques have led the clinical and academic community to reconsider how oropharyngeal cancer is managed. Comparative and risk-stratification trials are urgently required and ongoing.

The diagnosis of cancer of unknown primary (CUP) in head and neck occurs when the treating clinicians have utilised all available diagnostic tests and failed to identify the origin of the disease. There is no agreed consensus on which diagnostic investigations to use, or the order in which to use them in, although broad recommendations exist. Small tumours arising in the tongue base can be below the limits of resolution of conventional diagnostic techniques. Given the difficulty in targeting the tongue base, current practice involves blind random biopsies, which leads to a variable detection rate. Robotically assisted surgical removal of the tongue base, tongue base mucosectomy (TBM) has been shown to improve diagnostic yield. This study reports the diagnostic hit rate for tongue base primaries using this technique.

Persistent throat symptoms are common in adults. Globus pharyngeus (a feeling of a lump in the throat), dysphonia, throat clearing, cough, excessive phlegm, throat pain, and postnasal secretions are present in up to 25% of primary care attenders, and more than 60 000 people are referred to secondary otolaryngological care annually.1 Treating persistent throat symptoms with gastric acid suppression has been in vogue for more than a decade, on the basis that they represent “atypical” manifestations of gastro-oesophageal reflux disease (GORD).2 So called extraoesophageal reflux or laryngopharyngeal reflux is internationally acknowledged as a separate GORD subcategory from “typical” oesophageal reflux disease.3 However, the relation between gastric reflux and persistent throat symptoms, and the role of proton pump inhibitor (PPI) treatment remains controversial.4 5 More than half of UK otolaryngologists prescribe PPIs for persistent throat symptoms.6 The message has also filtered through to primary care that PPIs are a reasonable “empirical” treatment. PPI treatment is a substantial expense for healthcare systems and increasingly treatment of persistent throat symptoms is adding to this. The cost of PPI treatment to the National Health Service in England for all conditions, including persistent throat symptoms, was £425m (€540m;
