To investigate variations in the management and outcomes of peritonsillarabscesses, and to develop a trainee collaborative network in the UK.

Data were collected prospectively on suspected peritonsillar abscess casespresenting over a 2-month period at 42 participating secondary care centres,covering a population of 16 million. The primary outcome was an adverseevent at 30 days, defined as re-presentation or re-drainage.

Eighteen per cent of the 325 cases experienced an adverse event. Follow-updata were valid for 90 per cent of cases. Regression analyses showed asignificant reduction in adverse events in the 12 per cent of patients whowere discharged within 12 hours, and there was no significant increase inadverse events for the 70 per cent receiving corticosteroids.

Out-patient management of peritonsillar abscess is not commonly practised inthe UK. Corticosteroid usage is common and appears safe. This studydemonstrates that trainees working in collaboration can effectively deliverprospective multicentre cohort studies in the UK.

To investigate the assessment and management of paediatric snoring and obstructive sleep apnoea in UK otolaryngology departments.

A telephone questionnaire survey of UK otolaryngology departments was conducted over a 16-week period.

The response rate was 61 per cent (85 out of 139 trusts). Use of pre-operative pulse oximetry was reported by 84 per cent of respondents, mainly to diagnose obstructive sleep apnoea (73 per cent) or stratify post-operative risk (46 per cent). Thirty-one per cent of respondents reported using post-operative pulse oximetry. Twenty-five per cent of respondents have a dedicated management protocol for paediatric obstructive sleep apnoea and snoring. Thirty-four per cent require prior clinical commissioning group approval before performing surgery. Fifty-eight per cent of respondents reported following up their obstructive sleep apnoea patients after surgery. The mean follow-up period (±standard deviation) was 6.8 ± 1.2 weeks.

There is variation in the assessment and management of paediatric snoring and obstructive sleep apnoea across the UK, particularly in the use of pre- and post-operative pulse oximetry monitoring, and further guidelines regarding this are necessary.

This study aimed to assess the utility of onlay pectoralis major myofascial flap in preventing pharyngocutaneous fistula following salvage total laryngectomy.

A retrospective analysis was performed of 172 patients who underwent salvage laryngectomy for recurrent carcinoma of the larynx or hypopharynx between 1999 and 2014. One hundred and ten patients underwent primary closure and 62 patients had pectoralis major myofascial flap onlay.

The overall pharyngocutaneous fistula rate was 43 per cent, and was similar in both groups (primary closure group, 43.6 per cent; onlay flap group, 41.9 per cent; p = 0.8). Fistulae in the onlay flap group healed faster: the median and mean fistula duration were 37 and 55 days, respectively, in the primary closure group and 20 and 25 days, respectively, in the onlay flap group (p = 0.008).

Use of an onlay pectoralis major myofascial flap did not decrease the pharyngocutaneous fistula rate, although fistula duration was shortened. A well-designed randomised-controlled trial is needed to establish parameters for its routine use in clinical practice.

Otological symptoms (otalgia, subjective hearing loss, blocked ear sensation, tinnitus and vertigo) associated with temporomandibular disorders are documented features of Costen's syndrome. However, the origin of these symptoms and the causes of hearing loss are unknown. This study aimed to characterise hearing loss in a large number of patients with temporomandibular disorders. The causes of these symptoms were explored in patients with otological symptoms and normal audiometric findings.

A prospective case study and literature review were performed. The audiometric features of 104 temporomandibular disorder patients were compared with those of 110 control participants.

A large proportion of temporomandibular disorder patients had several otological symptoms. Twenty-five per cent of unilateral or bilateral temporomandibular disorder patients had either unilateral (ipsilateral) or bilateral hearing loss; respectively, which was usually mild (p = 0.001). Hearing loss was predominantly sensorineural.

The main cause of otological symptoms (apart from otalgia) and of audiometric findings in temporomandibular disorder patients is postulated to be an altered middle-ear to inner-ear pressure equilibrium.

Carbon dioxide laser posterior transverse cordotomy is a common option for bilateral vocal fold paralysis. This study prospectively evaluated aerodynamic and acoustic effects of unilateral carbon dioxide laser posterior transverse cordotomy in bilateral vocal fold paralysis patients.

The study comprised 11 bilateral vocal fold paralysis patients (9 females, 2 males), with a mean age of 46.6 ± 14.1 years. All patients were treated by laser posterior transverse cordotomy. Pre-operative and two-month post-operative assessments were conducted, including: dyspnoea scales, maximum phonation time measurement, spirometry and bicycle ergometry.

All subjective and objective aerodynamic parameters showed statistically significant improvements between the pre- and post-operative period. Objective spirometric and ergometric parameters showed a significant increase post-operatively. The changes in objective voice parameters (fundamental frequency (f0), jitter, shimmer, soft phonation index and noise-to-harmonic ratio) were statistically non-significant; however, there was a significant improvement in subjective voice parameters post-operatively, as assessed by the voice handicap index and grade-roughness-breathiness-asthenia-strain scale (p = 0.026 and p = 0.018 respectively).

Unilateral carbon dioxide laser posterior transverse cordotomy is an effective procedure that results in improved dyspnoea and aerodynamic performance with some worsening of voice parameters.

To evaluate the effects of autologous serum usage on throat pain, haemorrhage and tonsillar fossa epithelisation in patients after tonsillectomy.

Thirty-two patients (aged 4–15 years) were included in the study. Tonsillectomy was performed and autologous serum was administered topically to the right tonsillar fossa during the operation, and at 8 and 24 hours post-operatively. The left side served as the control. A visual analogue scale was used to record the patient's pain every day. Each patient's oropharynx was observed on the 5th and 10th post-operative days to examine bleeding and epithelisation.

The pain scores for the side administered autologous serum were significantly lower than those for the control side, on the night following the operation and on the 1st, 2nd, 5th and 6th post-operative days. Tonsillar fossa epithelisation was significantly accelerated on the study side compared with the control side on the 5th and 10th post-operative days.

In tonsillectomy patients, topically administered autologous serum contributed to throat pain relief and tonsillar fossa epithelisation during the post-operative period.

Sublingual immunotherapy in patients with allergic rhinitis sensitised to house dust mites is safe, but its efficacy is controversial and sublingual immunotherapy with Blomia tropicalis has not yet been studied. This study sought to evaluate the efficacy of sublingual immunotherapy with house dust mite extract in children and adults with house dust mite allergic rhinitis over a period of two years.

A prospective observational study was conducted of children and adults diagnosed with house dust mite allergic rhinitis who were treated with sublingual immunotherapy from 2008 to 2012. Total Nasal Symptom Scores, Mini Rhinoconjunctivitis Quality of Life scores and medication usage scores were assessed prospectively.

Thirty-nine patients, comprising 24 children and 15 adults, were studied. Total Nasal Symptom Scores and Mini Rhinoconjunctivitis Quality of Life scores dropped significantly at three months into therapy, and continued to improve. Medication usage scores improved at one year into immunotherapy.

Sublingual immunotherapy with house dust mite extracts, including B tropicalis, is efficacious as a treatment for patients with house dust mite allergic rhinitis.

• All patients with head and neck cancer (HNC) should undergo tumour classification and staging prior to treatment. (R)

• Pre-therapeutic clinical staging of HNCs should be based on at least a C2 factor (evidence obtained by special diagnostic means, e.g. radiographic imaging (e.g. computed tomography, magnetic resonance imaging or ultrasound scan), endoscopy, biopsy and cytology). (R)

• Imaging to evaluate the primary site should be performed prior to biopsy to avoid the effect of upstaging from the oedema caused by biopsy trauma. (G)

• Panendoscopy is only recommended for symptomatic patients or patients with primary tumours known to have a significant risk of a second (synchronous) primary tumour. (G)

A prospective randomised study was conducted at a tertiary care hospital to evaluate the effects of financial incentives for smoking cessation targeted at a high-risk population.

Patients with a past history of head and neck cancer were voluntarily enrolled over a two-year period. They were randomised to a cash incentives or no incentive group. Subjects were offered enrolment in smoking cessation courses. Smoking by-product levels were assessed at 30 days, 3 months and 6 months. Subjects in the incentive group received $150 if smoking cessation was confirmed.

Over 2 years, 114 patients with an established diagnosis of head and neck cancer were offered enrolment. Twenty-four enrolled and 14 attended the smoking cessation classes. Only two successfully quit smoking at six months. Both these patients were in the financially incentivised group and received $150 at each test visit.

Providing a financial incentive for smoking cessation to a population already carrying a diagnosis of head and neck cancer in order to promote a positive behaviour change was unsuccessful.

This study aimed to compare two sampling methods for nasal nitric oxide in healthy individuals and allergic rhinitis patients, and to examine the within-subject reliability of nasal nitric oxide measurement.

The study included 23 allergic rhinitis patients without concomitant asthma and 10 healthy individuals. For all participants, nitric oxide levels were measured non-invasively from the lungs through the mouth (i.e. the oral fractional exhaled nitric oxide) and the nose. Nasal nitric oxide was measured by two different methods: (1) nasal aspiration via one nostril during breath holding and (2) single-breath quiet exhalation against resistance through a tight facemask (i.e. the nasal fractional exhaled nitric oxide).

Compared with healthy participants, allergic rhinitis patients had significantly higher average oral and nasal nitric oxide levels. All methods of nitric oxide measurement had excellent reliability.

Nasal nitric oxide measurement is a useful and reliable clinical tool for diagnosing allergic rhinitis in patients without asthma in an out-patient setting.

This study aimed to develop a functional model of subglottic stenosis by inducing direct airway irritation in transplanted mouse laryngotracheal complexes.

Laryngotracheal complexes from C57BL/6 mice were harvested and divided into three groups: uninjured, mechanically injured and chemically injured. Donor laryngotracheal complexes from each group were placed in dorsal subcutaneous pockets of recipient mice. Each week, the transplanted laryngotracheal complexes were harvested, and tissues were fixed, sectioned, and stained with haematoxylin and eosin. Representative slides were reviewed by a blinded pathologist, to determine the formation of granulation tissue, and graded as to the degree of granulation formation.

Direct airway irritation induced granulation tissue formation under the disrupted epithelium of airway mucosa; this was seen as early as two weeks after chemical injury.

Results indicate that granulation tissue formation in a murine model may be an efficient tool for investigating the development and treatment of subglottic stenosis.

Dedicated otolaryngology high dependency units are uncommon. This paper reports the first experiences of such a facility in the UK, assessing reason for admission, duration of stay, occupancy rate and need for care escalation. The study sought to assess the presence of similar units in the UK.

A retrospective review of high dependency unit admissions over an 18-month period and a national survey of otolaryngology departments in the UK were conducted to establish the overall presence and location of similar high dependency units.

A total of 128 patients were admitted during the study period, mainly following surgery and because of airway compromise. The average duration of stay was 2–3 days (range, 1–12 days). The occupancy rate was 31.7 per cent. No patients required their care to be escalated to the intensive care unit. Seven similar high dependency units were identified in the UK.

The care provided prevented the need for escalation of care to an intensive care unit. This challenges the need for patient management on intensive care units following major surgery or airway compromise for those not requiring assisted ventilation. High dependency units similar to ours are not widespread.

• Accurate diagnosis of the type of malignancy is a key component of effective management. (R)

• Surgeons and oncologists should understand the scope and limitations of cellular pathology in order to inform multidisciplinary discussions. (R)

• A clinically suspected diagnosis of malignancy should be confirmed by biopsy or cytology before operation. (R)

• Cytopathological diagnoses should be discussed with surgeons and radiologists to maximise the information gained from each modality of investigation. (R)

• Pathological investigations are the basis for accurate cancer staging and stratification of clinical outcomes. (R)

Head and neck cancer emergency presentations are uncommon but persistent. However, there is little published literature on this aspect of cancer and patient demographics. This study aimed to assess the incidence, patient profile, tumour site and stage of emergency cancer presentations in our region.

Retrospective review of regional cancer database over a five-year period.

Emergency presentations accounted for 7 per cent of all cases. There was no difference in patient age and risk factors between the emergency and non-emergency presentations. The emergency presentation group showed a greater proportion of female patients compared to the non-emergency presentation group (30 vs 15 per cent). In all emergency presentations, the cancer was at advanced stages. Oropharyngeal cancer was the commonest emergency presentation of cancer, but the third commonest in the non-emergency group.

Emergency presentations are increasing annually. Female patients and oropharyngeal cancer showed greater representation compared to male patients and laryngeal cancer.

Surgeons are exposed to a variety of occupational risks, including work-related musculoskeletal disorders. This study investigated the prevalence of these latter disorders amongst UK ENT surgeons and compared this with the existing literature.

A survey containing questions on work-related musculoskeletal disorders was distributed to the entire membership of ENT-UK electronically, with the assistance of its Survey Guardian. A literature review on the subject was then performed.

A total of 323 completed questionnaires were received (a 24 per cent response rate). Work-related musculoskeletal disorders had been experienced by 47.4 per cent of respondents. There were no statistical differences between the occurrence of work-related musculoskeletal disorders and: grade, length of time spent in the specialty or the subspecialty of respondents. Eighty-five per cent of affected surgeons sought treatment, with 22.9 per cent taking time off work and six surgeons retiring early. The literature review only identified five related studies.

Despite the scarcity of studies, work-related musculoskeletal disorders are common amongst ENT surgeons in the UK. Such disparity highlights the need for more research and appropriate ergonomic intervention within the specialty.

Giant basal cell carcinoma, in which the tumour measures 5 cm or greater in diameter, is a very rare skin malignancy that accounts for less than 1 per cent of all basal cell tumours. Very few studies have reported on the incidence, resection and reconstruction of this lesion worldwide.

In total, 17 patients with giant basal cell carcinoma of the head and neck region underwent surgical excision and reconstruction at our hospital. Medical charts were retrospectively reviewed and analysed.

The lesion was usually in the forehead, eyelid, lips or nasal-cheek region. The greatest diameter ranged from 5 to 11 cm, with 5–6 cm being the most common size at the time of presentation. All patients had their tumour resected and reconstructed in a single-stage procedure, mostly with a local advancement flap, and with no post-operative flap failure.

Giant basal cell carcinoma of the head and neck can be successfully treated with a local flap in a single-stage approach.

To assess the distance between the bony groove created during subannular tubes placement and the chorda tympani, and examine the depth of the hypotympanum and retrotympanum.

Grooves drilled in cadaver temporal bones at two levels were imaged to measure: the distance between the chorda tympani nerve and the tympanic sulcus, and the depth of the hypotympanum and the retrotympanum relative to the annulus.

The chorda tympani was between 0 and 5 mm from the groove cut across the annulus. The hypotympanum average depth was 2 mm (0.44–6.40 mm) and the retrotympanum average depth was 1 mm (0–2.53 mm).

Grooves drilled across the tympanic sulcus should be placed at a point 20 per cent of the height of the tympanic membrane or lower; this will ensure least risk of injury to the chorda tympani nerve. The depth of the hypotympanum and retrotympanum dictates that the posteroinferior part of a subannular tube flange should be approximately 2 × 1 mm.

Inadvertent (or incidental) parathyroidectomy can occur during thyroidectomy. However, the factors associated with inadvertent parathyroidectomy remain unclear. This study aimed to report the rate of inadvertent parathyroidectomy during thyroidectomy and associated risk factors.

Variables including fine needle aspiration cytology findings, age, sex, thyroid weight, concurrent neck dissection, extent of thyroidectomy, and the presence of cancer and parathyroid tissue within the specimen were recorded for 266 patients. The incidence of post-operative hypocalcaemia was also recorded. Univariate and multivariate analysis were performed to identify factors associated with inadvertent parathyroidectomy.

The inadvertent parathyroidectomy rate was 16 per cent. Univariate analysis revealed that cancer and concurrent neck dissection predicted inadvertent parathyroidectomy. On multivariate analysis, only concurrent neck dissection remained an independent predictor of inadvertent parathyroidectomy: it was associated with a fourfold increase in inadvertent parathyroidectomy.

The inadvertent parathyroidectomy rate was 16 per cent and concurrent neck dissection was identified as an independent predictor of inadvertent parathyroidectomy.
