ObjectiveNumerous factors are considered to impact on the rate of complications during salvage total laryngectomy procedures. Neck dissection could be one of these factors. This study analysed the pattern of lymph node metastasis and rate of occult neck disease during salvage total laryngectomy as well as the impact of neck dissection on survival and complication rates.MethodThis was a retrospective analysis of a prospectively maintained laryngectomy database in two large tertiary teaching hospitals.ResultsThe rate of occult neck disease was 11.1 per cent. Most cases with occult neck disease had rT4 disease. Patients with complications, advanced tumour stage and positive margins had a significant decrease in overall survival. Patients receiving elective neck dissection did not have any survival benefit. Positron emission tomography-computed tomography showed a very high specificity and negative predictive value.ConclusionAccording to the low risk of occult neck disease when using contemporary imaging techniques as well as the lack of impact on survival, conservative management of the neck should be considered for crT1-T3 recurrence.

BackgroundThe introduction of transoral robotic surgery into routine management of patients is complex. It involves organisational, logistical and clinical challenges. This study presents our experience of implementing such a programme and provides a blueprint for other centres willing to establish similar services.MethodsImplementation of the robotic surgery programme focused on several key domains: training, logistics, governance, multidisciplinary team awareness, pre-operative imaging, anaesthesia, post-operative care, finance, patient selection and consent. Programme outcomes were evaluated by assessing operative outcomes of the first 117 procedures performed.ResultsThe success of the transoral robotic surgery programme has been possible because of the scrupulous planning phase before the first procedure, and the time invested on team awareness and training.ConclusionImplementation of a new transoral robotic surgery service has led to: the development of a dedicated transoral robotic surgery patient care protocol, the performance of progressively more complex procedures, the inclusion of transoral robotic surgery training and the establishment of several research projects.

Three-dimensional (3D) image reconstruction of tumors based on serial histological sectioning is one of the most powerful methods for accurate high-resolution visualization of tumor structures. However, 3D histological reconstruction of whole tumor has not yet been achieved. We established a high-resolution 3D model of molecular marked whole laryngeal cancer by optimizing the currently available techniques. A series of 5,388 HE stained or immunohistochemically stained whole light microscopic images (200 ×) were acquired (15.61 TB).The data set of block-face images (96.2 GB) was also captured. Direct volume rendering of serial 6.25 × light microscopy images did not demonstrate the major characteristics of the laryngeal cancer as expected. Based on fusion of two datasets, the accurate boundary of laryngeal tumor bulk was visualized in an anatomically realistic context. In the regions of interest, micro tumor structure, budding, cell proliferation and tumor lymph vessels were well represented in 3D after segmentation, which highlighted the advantages of 3D reconstruction of light microscopy images. In conclusion, generating 3D digital histopathological images of a whole solid tumor based on current technology is feasible. However, data mining strategy should be developed for complete utilization of the large amount of data generated.

Objective The global coronavirus disease 2019 (COVID-19) pandemic has necessitated rapid alterations to diagnostic pathways for head and neck cancer patients that aim to reduce risk to patients (exposure to the hospital environment) and staff (aerosol-generating procedures). Transoral fine needle aspiration cytology offers a low-risk means of rapidly diagnosing patients with oral cavity or oropharyngeal lesions. The technique was utilised in selected patients at our institution during the pandemic. The outcomes are considered in this study. Method Diagnostic outcomes were retrospectively evaluated for a series of patients undergoing transoral fine needle aspiration cytology of oral cavity and oropharyngeal lesions during the COVID-19 pandemic. Results Five patients underwent transoral fine needle aspiration cytology, yielding lesional material in 100 per cent, with cell blocks providing additional information. In one case, excision biopsy of a lymphoproliferative lesion was required for final diagnosis. Conclusion Transoral fine needle aspiration cytology can provide rapid diagnosis in patients with oral cavity and oropharyngeal lesions. Whilst limitations exist (including tolerability and lesion location), the technique offers significant advantages pertinent to the COVID-19 era, and could be employed in the future to obviate diagnostic surgery in selected patients.

Penetrating neck injuries are becoming more common because of the increasing prevalence of knife and gun crimes. The immediate and long-term consequences of injury to the neck can be significant because of the close relationship of important anatomical structures in a confined space. Delayed recognition of major injury and inadequate treatment results in high morbidity and mortality. Developing a clear understanding of the underlying anatomy, common mechanisms of injury and principles of management will provide first responders, emergency doctors and trauma surgeons with confidence in appropriate evidence-based management. Early involvement of otolaryngologists or head and neck surgeons is advisable. Two cases of penetrating neck injury from the June 2017 London Bridge terror attack are discussed.

Objectives: Squamous cell carcinoma of the nasal vestibule is rare variant of skin cancer. The TNM classification for skin cancer has been used, whereas, Wang has devised an independent staging system, which he stated was more accurate. The purpose of this study was to analyse the prognostic indicators for survival in a patients with nasal vestibule cancer from the Princess Margaret Hospital, Toronto. Design: A retrospective review of case notes from the Princess Margaret Hospital archives was performed. Setting: The Princess Margaret Hospital/Ontario Cancer Institute is the tertiary regional Head and Neck Oncology Centre for ON, Canada. Participants: All patients with nasal vestibule cancer (ICD10 C300) were included. Main outcome measures: Univariate and multivariate analyses were performed and Kaplan–Meier survival curves constructed. Results: Eighty-four patients were identified. The mean age was 67, there was a male preponderance of 2 : 1. Primary radical radiation was used in 77% of patients. Age (P = 0.02), N stage (P = 0.0001) and Wang classification (P = 0.0001) were associated with prediction of overall survival using multivariate analysis. Grade, depth of invasion and N stage were associated with disease-free survival outcome. A 5-year overall survival rate of 58% and disease-free survival of 52% was seen. Conclusion: Nasal vestibule cancer behaves in a more aggressive manner than any other skin cancers affecting the head and neck. The Wangs’ classification appears to be a better prognostic indicator for overall survival then the TNM classification for skin cancer.

The current management of thyroid lymphomas (TL) includes the combined use of chemotherapy and radiotherapy, with surgery mainly confined to diagnosis through an open biopsy following ultrasound-guided fine-needle aspiration cytology (US-FNAC).To analyse the clinical presentation and methods of diagnosis of TL, its pitfalls and the management of these tumours presenting with compression symptoms and airway obstruction.A retrospective review of nine patients diagnosed with TL at Guy's and St Thomas Hospital NHS Foundation Trust in London over the past 5 years.Nine consecutive patients were identified with the diagnosis of TL, and seven (78%) of them being women and with a mean age of 65 years. All patients presented with an anterior neck mass while four (44.4%) presented with stridor and vocal cord palsy. Two (22.2%) presented with a hoarse voice, dysphagia, and only one patient had a B symptom of weight loss. FNAC was diagnostic in three patients (33.3%) and a report of multi-nodular goitre in one patient. There was clinical suspicion of TL in three patients (33.3%). Of the three patients presenting with stridor, two had an open biopsy followed by the initiation of dexamethasone therapy and resolution of symptoms within 48 h. One patient had a partial thyroidectomy following a suspected diagnosis of multi-nodular goitre from US-FNAC. One patient required tracheostomy for airway management.Diagnosis of TL may be difficult. However, US-FNAC is useful in raising the suspicion of a TL. Open biopsy is still the definitive diagnostic tool of choice. In the emergency setting of airway obstruction, once definitive diagnosis is achieved, dexamethasone therapy and endotracheal intubation for airway management are all that is required for optimal management strategy. Surgical intervention has no role except for providing tissue for diagnosis.

The purpose of this study was to determine the oestrogen and progesterone receptor status of a selection of salivary tumours. Using immunohistochemistry, we detected nine oestrogen receptor and six progesterone receptor positive tumours from a sample of 36. One acinic cell carcinoma and two mucoepidermoid carcinomas demonstrated positivity for both receptors. We suggest that there may be role for oestrogen manipulation in the management of some salivary tumours.

Background Primary adenocarcinomas of the parotid gland are rare and account for less than 5% of all head and neck malignant neoplasms. There is considerable variation in biological behaviour within this group; low-grade tumours exhibit slow growth rates with minimal or no local invasion. High-grade tumours, however, show a high incidence of local recurrence and distant metastasis. Aim The purpose of this paper is to analyse the important prognostic indicators for this cancer. Methods A systematic review was performed involving 19 published studies from 1987 to 2005 which included 4631 patients. T stage, grade of tumour, N stage and adjuvant radiotherapy on overall (5 year) survival were analysed as prognostic indicators. Results T stage ( p = 0.041, hazard ratio 1.8 (confidence interval 1.2–2.9)), N stage ( p = 0.05, hazard ratio 1.1 (0.2–1.8)), and high-grade ( p = 0.001, hazard ratio 2.1 (1.5–2.7)) were associated with a significantly worse survival. The effect of adjuvant radiotherapy was to improve overall survival: p = 0.002, hazard ratio 2.9 (1.5–4.7). The mean 5 year survival for advanced high-grade parotid cancer was 35%. Conclusion High-grade advanced parotid cancers are associated with a poor survival. Adjuvant radiotherapy is indicated in these tumours and this improves survival.

The aim of this study was to determine the relationship between glottic space and breathy voice. Using a new computerized method of analysing the glottic area of video images with the Vocim computer system, 16 patients with a vocal cord palsy and 31 with non-organic dysphonia were examined. The quality of the breathy voice was assessed and correlated with the size of the glottic space during phonation. There was a positive (r = 0.70) correlation between glottic area and breathy voice in vocal cord palsy. There was no correlation (r = 0.002) in non-organic dysphonia. Therefore in this study population, for vocal cord palsy, glottic area is the dominant feature in determining voice quality. This relationship is not maintained in non-organic dysphonia.

Laryngomalacia is the most common paediatric airway problem presenting as stridor in the neonate. This congenital anomaly is thought to be caused by inward inspiratory collapse of the supraglottic larynx due to a prolapsed, tall and tubular epiglottis with flaccid aryepiglottic folds. The natural history of this condition usually results in spontaneous resolution by the second year of life. Although acquired cases of adult laryngomalacia have been reported, a search of the literature has yet to show any cases of idiopathic laryngomalacia. We present two cases of idiopathic acquired laryngomalacia in adults.

Tissue adhesives have been available and in use for more than 40 years. They have, however, never been popular for ossiculoplasty because of the reported excessive inflammatory reaction and ototoxicity. The authors present a case of ossicular disruption successfully repaired with tissue adhesive and review the literature.

An audit of 334 patients who underwent magnetic resonance imaging (MRI) as investigation for a possible diagnosis of vestibular schwannoma was carried out to assess adherence to previously agreed screening guidelines. This represents one year's activity. A posterior fossa tumour was identified in 12 patients. Scan requests were judged to be inappropriate for 28 cases. The issues surrounding the screening for acoustic neuroma are discussed.
