The post-operative tonsillectomy (POPT) study: A multi-centre prospective paediatric cohort study.

OBJECTIVES: Tonsillectomy is the most common operation performed by otolaryngologists in the UK, despite this we have a poor understanding of the post-operative recovery. We aimed to investigate post-operative bleeding and pain following paediatric tonsillectomy using a patient diary. DESIGN: Prospective observational cohort study. SETTING: Multi-centre study involving 12 secondary and tertiary otolaryngology units across the North of England. Patients were recruited from 1st March 2020 to 30th June 2022. Multilevel ordered logistic regression model statistics were performed. PARTICIPANTS: Children (≥4 years, ≤16 years) undergoing tonsillectomy (with or without adenoidectomy) for benign pathology. MAIN OUTCOME MEASURES: Frequency and severity of post-operative bleeding. Intensity and pattern of post-operative pain. RESULTS: In total 297 children were recruited, with 91 (30.6%) diaries eligible for analysis. Post-operative bleeding occurred in 44% of children. Most frequently blood in the saliva was reported (82.9%). Increasing age significantly increased bleeding odds by 17% per year (p = .001). Bleeding frequency decreased with higher surgeon grade (p = .003) and when performing intracapsular coblation tonsillectomy (p = .02) compared with other techniques. Lower age and intracapsular coblation tonsillectomy, against other techniques, significantly reduced rates of pain post-operatively (p < .0001 and p = .0008). CONCLUSION: A high level of low-level post-operative bleeding was observed. Pain scores remained high for 5 days post-operatively then gradually reduce to normal by day 13. Intracapsular coblation tonsillectomy appears to be superior to all other techniques in terms of reducing post-operative bleeding and pain. These findings should be used to guide patients in the consent process to inform them of the expected nature of post-surgical recovery.

A prospective multicentre external validation study of the Liverpool Peritonsillar abscess Score (LPS) with a no-examination COVID-19 modification.

OBJECTIVES: Our primary aim was to validate the Liverpool Peritonsillar abscess Score (LPS) externally in a new patient cohort. Our secondary aim was to modify the LPS in the light of the COVID-19 pandemic to produce a no-examination variant for use in this instance. DESIGN: Prospective multicentre external validation study. SETTING: Six different secondary care institutions across the United Kingdom. PARTICIPANTS: Patients over 16 years old who were referred to ENT with any uncomplicated sore throat such a tonsillitis or peritonsillar abscess (PTA). MAIN OUTCOME MEASURES: Sensitivity, specificity, positive predictive value and negative predictive value for both the original LPS model and the modified model for COVID-19. RESULTS: The LPS model had sensitivity and specificity calculated at 98% and 79%, respectively. The LPS has a high negative predictive value (NPV) of 99%. The positive predictive value (PPV) was slightly lower at 63%. Receiver operating characteristic (ROC) curve, including the area under the curve (AUROC), was 0.888 which indicates very good accuracy. CONCLUSIONS: External validation of the LPS against an independent geographically diverse population yields high NPV. This may support non-specialist colleagues who may have concerns about mis-diagnosing a PTA. The COVID-19 modification of the LPS has a similar NPV, which may be of use where routine oral examination is to be avoided during the COVID-19 pandemic.

The effect of fibrin sealant tissue glue in reducing post-operative collections following parotidectomy.

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. METHODS: Outcomes were studied retrospectively for 1 year prior to the introduction of FSTG (group A, n = 31), and prospectively for 1 year subsequently (group B, n = 29). Primary outcome measures were seroma/sialocele and haematoma rates. Secondary outcome measures of interest included the use of a surgical drain and the duration of hospital stay. Chi-squared statistics and Mann-Whitney U tests were used to compare the outcomes between groups as appropriate. RESULTS: Seroma/sialocele rates were significantly lower in group B than in group A (n = 2 [6.9%] versus n = 8 [25.8%], p = 0.01) (Fig. 1), with an absolute risk reduction of 18.9%, a relative risk reduction of 26.7%, and a number needed to treat of 5.3. Haematoma rates were similar between groups (n = 0 [0%] versus n = 1 [3.2%], p = 0.36) (Fig. 2). In group A, a surgical drain was used in 24 cases (77.4%), while no cases in group B were drained.Fig. 1Seroma ratesFig. 2Haematoma rates CONCLUSION: The use of FSTG appears to significantly reduce the risk of post-parotidectomy seroma/sialocele formation and facilitates safe, drain-free daycase surgery. We hope this report will prompt other departments to consider using this technique and that our findings will help foster further appraisal in larger, prospective studies going forward.

Outcomes and prognosticators in regionally recurrent cutaneous squamous cell carcinoma of the head and neck.

INTRODUCTION: Data regarding regionally metastatic cutaneous squamous cell carcinoma of the head and neck (cSCCHN) is limited and derived almost exclusively from Australian and United States (US) institutions. We report the first United Kingdom perspective, with the aims of benchmarking survival outcomes and identifying clinically relevant prognosticators. MATERIALS AND METHODS: Ninety-one patients with regionally recurrent cSCCHN treated with curative intent over a ten-year period (2009-2018) were studied retrospectively. Time-to-event analyses were used to estimate oncological outcomes, and log-rank statistics and Cox proportional hazards models used to examine potential prognosticators. Receiver operating characteristics were also used to analyse the influence of nodal disease burden. RESULTS: Parotid involvement (with or without neck involvement) was most common (79.2%), and time to recurrence in those with parotid disease alone significantly shorter than for any other disease distribution (p = 0.034). Respective five-year overall, disease-specific, and disease-free survival estimates were 43.8%, 63.8%, and 36.2%. Extracapsular spread (ECS) portended reduced DFS and DSS (p = 0.012 and p = 0.005 respectively). Increasing nodal burden (≥4 involved nodes) also reduced DSS (p = 0.020), while parotid disease alone predicted more favourable DSS (p = 0.008). ECS and isolated parotid involvement remained significant on multi-variate analysis (p = 0.014 and p = 0.028 respectively). CONCLUSIONS: Oncological outcomes were unfavourable but broadly consistent with previous reports, notionally lending support to a more proactive approach in managing the clinically node negative neck/parotid in selected high-risk cases. Our data also support distinct parotid classification and consideration of involved lymph node number in future staging systems.
