Background
The key step in the evaluation of parotid lumps is to differentiate benign lesions from malignant ones. The ENT-UK guidelines advocate the use of fine needle aspiration cytology (FNAC). There are minimal evidence-based data concerning alternative diagnostic tools.
Objective
We decided to investigate the accuracy of magnetic resonance imaging (MRI) compared with FNAC in correctly diagnosing malignant parotid tumours.
Methods
All patients who had undergone parotidectomy from January 2012 to June 2013 were identified. The parotid sample list was acquired from the pathology department. Only parotidectomies carried out for primary tumour removal were considered; all parotidectomies performed as part of a complete dissection for other primary malignancies were excluded.
Retrospective analysis identified the investigations that took place prior to surgery. The results of each test were compared to the definitive histopathology result, which was considered the ‘gold standard’ diagnosis.

Data represent numbers of patients unless indicated otherwise. MRI = magnetic resonance imaging; FNAC = fine needle aspiration cytology; PPV = positive predictive value; NPV = negative predictive value
Conclusion
Accurate pre-operative assessment of benign versus malignant parotid lumps helps the surgeon to plan excision and determine the need for neck dissection; it can also significantly alter the incidence of peri-operative facial nerve paresis or paralysis.
Our results highlight the sensitivity of MRI as a diagnostic tool in differentiating malignant from benign parotid lesions. Fine needle aspiration cytology demonstrates significant accuracy in benign lesions, but appears limited for malignant pathology. There may be a substantial role for MRI; we feel this should be explored by analysing a larger cohort of malignant parotid tumour data, the outcomes of which may have a potentially significant impact on changing current recommended practice.
Background and objective
Over 55 000 tonsillectomies are performed in England every year. Historically, patients stay overnight. The Royal College of Surgeons deemed tonsillectomies inappropriate for day-case surgery in 1985, citing reactionary haemorrhage as the contraindication. Since then, published evidence has concluded that this risk is low, prompting a shift in practice. We present the challenges of improving rates of day-case tonsillectomies in the absence of a dedicated day-case unit.
Methods
Data on day-case tonsillectomy rates in both children and adults were collected over six months in 2011 (n=123). New local protocols were designed specifically for day-case tonsillectomies. Day-case tonsillectomy rates were re-audited over six months in 2012 (n = 125) to assess the effect of intervention.
Results
Day-case tonsillectomy rates increased in children from 9 to 25 per cent. A similarly significant increase was noted in adults, from 6 to 43 per cent. There were two re-admissions over the re-audit period, neither of which involved day-case patients.
Conclusion
This project demonstrates how healthcare processes can be streamlined to save time and resources without compromising patient safety. By engaging colleagues and patients, we made dramatic improvements, without needing to construct an expensive, purpose-built day-case facility, which is all the more relevant in times of efficiency savings.
Background and objective
‘Procedures of limited clinical value’ is a term first highlighted in the McKinsey report (2009), which examined potential cost-cutting measures within the future National Health Service (NHS). It is a term used by some trusts to describe surgical procedures that, they feel, are not cost effective. With the NHS now facing intense financial pressures, we undertook a study to examine whether five core procedures within the specialty of ENT had been restricted.
Methods
Numbers of operative procedures carried out over a six-year period (2007–2012) at six separate hospitals across the Wessex Deanery were obtained. Five surgical ENT procedures commonly classified as procedures of limited clinical value were studied: tonsillectomy, adenoidectomy, septorhinoplasty, pinnaplasty, and myringotomy with grommet insertion.
Results
In total, 22 839 surgical procedures were included. A year-on-year variability in the number of each of the five individual procedures was observed. However, when comparing the cumulative data from pre-2009 to post-2009, there were no significant changes in the numbers of procedures carried out. On individual examination of hospitals, no significant changes were seen in the numbers of tonsillectomies, adenoidectomies and myringotomies performed. However, a significant drop in the numbers of pinnaplasty and septorhinoplasty procedures was observed in some hospitals.
Conclusion
Since the introduction of the concept of procedures of limited clinical value in 2009, there has not been a significant drop in the number of core ENT procedures performed across the Wessex region. However, there seems to be significant inter-hospital variation with respect to some ENT procedures. With the introduction of clinical commissioning, the inter-hospital variation in surgical provision may well increase.
