A two-centre experience of tonsil biopsies in the investigation of patients with tonsillar asymmetry.

INTRODUCTION: We aim to evaluate our experience of tonsil biopsies in the investigation of patients presenting with asymmetrical tonsils. METHODS: A two-centre retrospective analysis of all patients who underwent histology sampling of the palatine tonsils between 1 January 2013 and 31 December 2018 was completed. Data collected included patient demographics, method of obtaining tonsil tissue, histological diagnosis and need for repeat tissue sampling. A follow-up period of 36 months was allowed to establish whether any patients re-presented with missed diagnoses. RESULTS: In total, 937 patients were included for analysis: 375 (40.0%) had a biopsy, of which 191 (50.9%) were performed in clinic. The mean duration from initial appointment with the ear, nose and throat clinic to tissue sample collection was 17.6 days (range 0-327 days) for all biopsies, reducing to 0.2 days (range 0-17 days) for biopsies performed in clinic. This was significantly shorter than for tonsillectomies (mean 38.9 days, range 0-444 days; p<0.05). Of the patients who underwent tonsil biopsy, six (1.6%) had malignancy that was not unequivocally diagnosed on initial biopsy. In all six patients, prior clinical suspicion was high, and repeat tissue sampling was undertaken on receipt of negative histology results. CONCLUSIONS: Tonsil biopsy is a viable alternative to tonsillectomy for histology in the assessment of tonsil asymmetry. Tonsil biopsy in the outpatient setting has reduced surgical morbidity, significantly less delay in diagnosis, less inconvenience for patients and lower healthcare costs compared with formal tonsillectomy. Although tonsil biopsies should not be used in isolation, they can be useful in the investigation of patients presenting with tonsillar asymmetry.

Systematic review and meta-analysis of the diagnostic effectiveness of positron emission tomography-computed tomography versus magnetic resonance imaging in the post-treatment surveillance of head and neck squamous cell carcinoma.

OBJECTIVE: There is currently no consensus on the ideal protocol of imaging for post-treatment surveillance of head and neck squamous cell carcinoma. This study aimed to consolidate existing evidence on the diagnostic effectiveness of positron emission tomography-computed tomography versus magnetic resonance imaging. METHOD: Systematic electronic searches were conducted using Medline, Embase and Cochrane Library (updated February 2021) to identify studies directly comparing positron emission tomography-computed tomography and magnetic resonance imaging scans for detecting locoregional recurrence or residual disease for post-treatment surveillance. RESULTS: Searches identified 3164 unique records, with three studies included for meta-analysis, comprising 176 patients. The weighted pooled estimates of sensitivity and specificity for scans performed three to six months post-curative treatment were: positron emission tomography-computed tomography, 0.68 (95 per cent confidence interval, 0.49-0.84) and 0.89 (95 per cent confidence interval, 0.84-0.93); magnetic resonance imaging, 0.72 (95 per cent confidence interval, 0.54-0.88) and 0.85 (95 per cent confidence interval, 0.79-0.89), respectively. CONCLUSION: Existing studies do not provide evidence for superiority of either positron emission tomography-computed tomography or magnetic resonance imaging in detecting locoregional recurrence or residual disease following curative treatment of head and neck squamous cell carcinoma.

The effect of surgical complications on ENT trainees.

BACKGROUND: The 'second victim phenomenon' is a term attributed to the traumatic effect a medical error can have on healthcare professionals. Patient safety incidents have been shown to occur in as many as one in seven patients in hospital. These incidents cause significant, potentially devastating, trauma to patients and their relatives, and can have deep and long-lasting effects on the health professionals involved. These incidents can have a negative impact on doctors' emotional wellbeing; their professional practice in relation to this impact has not been extensively investigated in surgical trainees. METHOD: A survey of UK otolaryngology trainees was conducted to investigate the effects of complications and medical errors on trainees, and examine how these are discussed within departments. RESULTS AND CONCLUSION: The findings suggest that further training is required and would be warmly received by otolaryngology trainees as part of higher surgical training.

Streamlining grommet pathways for otitis media with effusion and hearing loss in children: our experience.

BACKGROUND: Grommet insertion is a common surgical procedure in children. Long waiting times for grommet insertion are not unusual. This project aimed to streamline the process by introducing a pathway for audiologists to directly schedule children meeting National Institute for Health and Care Excellence Clinical Guideline 60 ('CG60') for grommet insertion.Method and resultsA period from June to November 2014 was retrospectively audited. Mean duration between the first audiology appointment and grommet insertion was 294.5 days (median = 310 days). Implementing the direct-listing pathway reduced the duration between first audiology appointment and grommet insertion (mean = 232 days; median = 231 days). There has been a reduction in the time between the first audiology appointment and surgery (mean difference of 62.5 days; p = 0.024), and a reduction in the time between second audiology appointment and surgery (28 days; p = 0.009). CONCLUSION: Direct-listing pathways for grommet insertion can reduce waiting times and expedite surgery. Implementation involves a simple alteration of current practice, adhering to National Institute for Health and Care Excellence Clinical Guideline 60. The ultimate decision regarding surgery still rests with ENT specialists.
