Adenoid hypertrophy is a common cause of upper airway obstruction, and adenoidectomy is one of the most frequently performed operations in children. Topical nasal steroids can act directly on nasopharyngeal lymphoid tissue to decrease its reactive inflammatory changes and potentially reduce its size.

To study the light microscopic changes in adenoidal lymphoid tissue after one month of topical steroid use.

Twenty-six children with adenoid hypertrophy grade 3 scheduled for adenoidectomy were randomly divided into two equal groups: one group received mometasone furoate aqueous nasal spray (Nasonex) 100 mcg/day for four weeks, and a control group received nasal normal saline 0.9 per cent for four weeks. The removed adenoids were examined histopathologically.

Adenoidal tissue from the mometasone group had less reactive germinal centres and less spongiosis compared to the control group. The latter showed proliferating, reactive, variable sized and shaped lymphoid follicles, with congested blood vessels in the interfollicular areas.

The use of intranasal mometasone furoate aqueous nasal spray (Nasonex) for one month reduced adenoidal tissue reactive cellular changes and its vascularity. This is, however, a pilot study; a longer treatment period is needed to assess the effect of treatment on adenoidal size.

Transnasal inferior meatal antrostomy is increasingly used for the treatment of post-Caldwell–Luc mucoceles in maxillary sinus. This study aimed to report the outcomes after inferior meatal antrostomy with a mucosal flap for recurrent mucoceles.

The records of patients who had undergone transnasal inferior meatal antrostomy with or without a mucosal flap were reviewed.

Transnasal endoscopic inferior meatal antrostomy with or without a mucosal flap was performed in 21 and 49 patients, respectively. No complications were observed. A closing of the antrostomy was found in 9 (18.4 per cent) of the 49 patients who underwent antrostomy without a mucosal flap. No closings were observed in the 21 patients who underwent antrostomy with a mucosal flap. There was a significant difference in the rate of closing for surgery with and without the mucosal flap.

Transnasal endoscopic inferior meatal antrostomy with a mucosal flap is a safe method for the treatment of post-Caldwell–Luc maxillary mucoceles that effectively prevents recurrence.

Opioid analgesics are often prescribed following rhinology surgery. This study aimed to evaluate whether the quantity of opioid analgesics prescribed is justified.

Patients were asked about their pain management post-operatively. Parameters recorded included: current pain (using a 10-point Likert scale); type of operation; the opioid analgesics prescribed; and the quantity of opioid tablets taken and other methods of pain relief used.

Thirty-five patients were successfully contacted. The median pain score at one week post-operation was 1 (interquartile range, 0–3). Of these 35 patients, 16 were prescribed opioids, whilst 19 were not. Patients prescribed opioids took a median of 8 tablets (interquartile range, 0.8–10.5) out of the 28 tablets prescribed.

The study shows that the quantity of post-operative opioid analgesics prescribed does not compare with the amount consumed by patients to relieve pain, resulting in a surplus of opioid medication which has the potential to be abused.

Patulous Eustachian tube is a benign but notoriously difficult condition to treat successfully. Symptoms include autophony of voice and breathing, and aural fullness.

This paper presents a series of 8 patients (12 ears) for whom a novel computed tomography guided injection of silicone elastomer suspension implant (Vox) was used to treat patulous Eustachian tube. This is the largest and only series in the current literature using this technique.

The combined complete and partial symptom resolution rate was 91 per cent. Complications related to the procedure are described. The pros and cons of this novel approach are also discussed in relation to traditional endoscopic transnasal techniques.

Computed tomography guided injection of Vox for the treatment of patulous Eustachian tube is suggested to be a feasible alternative to endoscopic transnasal approaches, particularly for refractory cases.

Head and neck soft tissue sarcoma is uncommon. It is both histologically and clinically heterogeneous, ranging from an indolent, locally destructive tumour, to a locally aggressive neoplasm with metastatic potential.

A retrospective review was conducted of all adult head and neck soft tissue sarcomas, including cases of malignant soft tissue sarcoma and all intermediate type tumours, diagnosed between 1997 and 2012.

Sixty-eight cases were identified in this series from the sarcoma multidisciplinary team. Seventeen different histological subtypes of sarcoma were identified. Neither age, gender nor tumour size were significant prognostic indicators for survival in this series.

Prognosis is dependent on histological subtype, underscoring the importance of histological classification. Some histological subtypes occur only once or twice in a decade, even within a large regional referral centre. An accumulation of evidence from relatively small case series is key in the long-term development of treatment strategies.

Adenotonsillectomy is frequently performed for obstructive sleep apnoea, but is associated with post-operative respiratory morbidity. This study assessed the effect of paediatric Otrivine (0.05 per cent xylometazoline hydrochloride) on post-operative respiratory compromise.

Paediatric patients undergoing adenotonsillectomy for obstructive sleep apnoea were included. The control group (n = 24) received no intervention and the intervention group (n = 25) received intra-operative paediatric Otrivine during induction using a nasal patty. Post-operative outcomes included pain, respiratory distress signs and medical intervention level required (simple, intermediate and major).

Post-operative respiratory distress signs were exhibited by 4 per cent of the Otrivine group and 21 per cent of the control group. Sixty-eight per cent of the Otrivine group required simple medical interventions post-operatively, compared to 42 per cent of the control group. In the Otrivine group, 4 per cent required intermediate interventions; none required major interventions. In the control group, 12.5 per cent required both intermediate and major interventions. Fifty per cent of the control group reported pain post-operatively, compared with 40 per cent in the Otrivine group.

Intra-operative paediatric Otrivine may reduce post-operative respiratory compromise in paediatric patients undergoing adenotonsillectomy for obstructive sleep apnoea. A randomised controlled trial is required.

This study aimed to record recent changes in the incidence and clinical and histopathological patterns of rhinoscleroma in the middle of Nile Delta in Egypt.

Twenty-eight patients with rhinoscleroma were included in this study. Patients who were attending the Department of Otolaryngology at Tanta University Hospitals from January 2014 to January 2019 were included. Cases were diagnosed by clinical, bacteriological and histopathological data. Nasal biopsies were taken for histopathological and electron microscopy studies. All patients received a twelve-week course of 500 mg ciprofloxacin tablets twice daily.

The rate of rhinoscleroma was shown to be decreasing compared with previous studies. In this study, the disease mainly affected the nose without involvement of the palate, lips, Eustachian tube or bronchi. Histopathological and electron microscopy analyses showed that most cases were in the atrophic and fibrotic stages rather than the granulomatous stage of disease.

The incidence of rhinoscleroma in Egypt is decreasing and its clinical and histopathological patterns are changing to less advanced forms. This may be explained by the improvement in socioeconomic conditions and methods of treatment.

Ki-67 is a monoclonal antibody that provides a means of evaluating the growth fraction of normal and neoplastic human cell populations. A Ki-67 index of less than 3 per cent is expected for a typical schwannoma. Vestibular schwannomas with an index of greater than 3 per cent are presumed to be actively proliferating and pose a theoretically higher risk for regrowth or recurrence.

A retrospective chart review was conducted. Ki-67 staining was performed and specimens were divided into two groups according to Ki-67 activity: less than 3 per cent (low index), and 3 per cent or greater (elevated index).

Eight patients (53.3 per cent) with elevated Ki-67 had recurrence or regrowth, versus five (8.5 per cent) in the low Ki-67 group. Among the 13 patients with recurrence or regrowth, the average Ki-67 value was 4.3 per cent. Among the 61 patients without recurrence or regrowth, the average Ki-67 value was 1.0 per cent.

The Ki-67 labelling index reliably identifies vestibular schwannomas with an elevated potential for recurrence or regrowth in subtotal or total resection cases. In patients with a Ki-67 index greater than 3 per cent, more frequent clinical examination and radiological follow up are recommended.

Comparing the feasibility of ovine and synthetic temporal bones for simulating endoscopic ear surgery against the ‘gold standard’ of human cadaveric tissue.

A total of 10 candidates (5 trainees and 5 experts) performed endoscopic tympanoplasty on 3 models: Pettigrew temporal bones, ovine temporal bones and cadaveric temporal bones. Candidates completed a questionnaire assessing the face validity, global content validity and task-specific content validity of each model.

Regarding ovine temporal bone validity, the median values were 4 (interquartile range = 4–4) for face validity, 4 (interquartile range = 4–4) for global content validity and 4 (interquartile range = 4–4) for task-specific content validity. For the Pettigrew temporal bone, the median values were 3.5 (interquartile range = 2.25–4) for face validity, 3 (interquartile range = 2.75–3) for global content validity and 3 (interquartile range = 2.5–3) for task-specific content validity. The ovine temporal bone was considered significantly superior to the Pettigrew temporal bone for the majority of validity categories assessed.

Tympanoplasty is feasible in both the ovine temporal bone and the Pettigrew temporal bone. However, the ovine model was a significantly more realistic simulation tool.

It is hypothesised that patients with muscle tension dysphonia have a high prevalence of dysphagia in comparison to normative values reported in the literature.

This prospective study included 44 subjects diagnosed with muscle tension dysphonia, based on symptoms and laryngoscopic findings, and 25 control subjects with no history of dysphonia and normal laryngeal examination findings. Demographic data included age, gender and smoking history. The aetiology of muscle tension dysphonia was classified as primary or secondary. Evaluation involved the Eating Assessment Tool (‘EAT-10’) questionnaire.

Patients’ mean age was 45.93 ± 14.95 years, with a female to male ratio of 1.2:1. Fourteen patients had primary muscle tension dysphonia, while 30 had secondary muscle tension dysphonia. Among patients with secondary muscle tension dysphonia, Reinke's oedema was the most common aetiology. There was a significant difference in the prevalence of dysphagia between the study group and the control group (40.9 per cent vs 8 per cent respectively, p < 0.05).

This study demonstrates a higher prevalence of dysphagia in patients with the presenting symptom of dysphonia and diagnosed with muscle tension dysphonia in comparison to subjects with no dysphonia.

Epistaxis is the most common ENT emergency. This study aimed to assess one-year mortality rates in patients admitted to a large teaching hospital.

This study was a retrospective case note analysis of all patients admitted to the Queen Elizabeth University Hospital in Glasgow with epistaxis over a 12-month period.

The one-year overall mortality for a patient admitted with epistaxis was 9.8 per cent. The patients who died were older (mean age 77.2 vs 68.8 years; p = 0.002), had a higher Cumulative Illness Rating Scale-Geriatric score (9.9 vs 6.7; p < 0.001) and had a higher performance status score (2 or higher vs less than 2; p < 0.001). Other risk factors were a low admission haemoglobin level (less than 128 g/dl vs 128 g/dl or higher; p = 0.025), abnormal coagulation (p = 0.004), low albumin (less than 36 g/l vs more than 36 g/l; p < 0.001) and longer length of stay (p = 0.046).

There are a number of risk factors associated with increased mortality after admission with epistaxis. This information could help with risk stratification of patients at admission and enable the appropriate patient support to be arranged.

To assess the effect of topical betahistine on Eustachian tube function in subjectively abnormal subjects in a hyperbaric chamber.

Active and passive Eustachian tube function was examined using tympanometry in a pressure chamber.

Active Eustachian tube function was tested against the negative middle ear pressure induced by increasing the chamber pressure to +3 kPa. One voluntary swallow decreased middle-ear pressure by a mean of 1.36 kPa. Passive Eustachian tube function was tested by measuring spontaneous Eustachian tube openings as the chamber pressure dropped from +10 kPa to ambient. Four distinct patterns of Eustachian tube behaviour were seen, three of which indicated Eustachian tube dysfunction. Betahistine had no positive effect on Eustachian tube opening, although previous animal studies had suggested a beneficial effect.

Topical betahistine had no effect on Eustachian tube function. Combining a hyperbaric chamber with tympanometry proved ideal for evaluating Eustachian tube function.

This study aimed to determine the predictors of disease progression after functional endoscopic sinus surgery in patients with chronic rhinosinusitis.

A total of 281 adult chronic rhinosinusitis patients who underwent primary bilateral functional endoscopic sinus surgery between 2007 and 2017 and had at least 12 months of follow-up endoscopic evaluation were examined. Patients were divided into eosinophilic (n = 205) and non-eosinophilic chronic rhinosinusitis groups (n = 76). In order to determine adverse factors, post-operative endoscopic appearance scores were analysed in relation to the pre- and intra-operative findings using multiple regression analyses.

The post-operative course of eosinophilic cases deteriorated over time, like the early period for non-eosinophilic cases. Frontal sinus polyps recurred early in eosinophilic chronic rhinosinusitis. Multivariate analyses indicated young adulthood, asthma, high computed tomography score and frontal sinus polyps as significant adverse predictors.

Early, appropriate estimation of sinonasal conditions appears to be crucial for successful surgical management of chronic rhinosinusitis.

Public awareness of ‘red flag’ symptoms for head and neck cancer is low. There is a lack of evidence regarding patient concerns and expectations in consultations for cancer assessment.

This prospective questionnaire study examined the symptoms, concerns and expectations of 250 consecutive patients attending an ‘urgent suspicion of cancer’ clinic at a tertiary referral centre.

The patients’ most frequent responses regarding their concerns were ‘no concerns’ (n = 72, 29 per cent); ‘all symptoms’ were a cause for concern (n = 65, 26 per cent) and ‘neck lump’ was a symptom causing concern (n = 37, 17 per cent). The expectations of patients attending clinic were that they would find out what was wrong with them, followed by having no expectations at all. Overall patient knowledge of red flag symptoms was lacking and their expectations were low.

Patients with non-cancer symptoms are frequently referred with suspected cancer. Patients with red flag symptoms are not aware of their significance and they have low expectations of healthcare.

To compare conventional cold curettage adenoidectomy with endoscopic assisted coblation adenoidectomy in terms of operative time, primary blood loss, post-operative residual tissue and post-operative pain.

This prospective non-randomised study was carried out on 60 patients aged 5–12 years. One group underwent conventional cold curettage adenoidectomy and the other underwent endoscopic assisted coblation adenoidectomy, with 30 patients per group.

Mean operation duration was significantly higher for endoscopic assisted coblation adenoidectomy. Mean blood loss was 44.33 ml in conventional cold curettage adenoidectomy and 32.47 ml in endoscopic assisted coblation adenoidectomy. The pain grade was significantly lower in endoscopic assisted coblation adenoidectomy. Forty per cent of patients who underwent conventional cold curettage adenoidectomy had adenoid tissue post-surgery, while it was completely absent in endoscopic assisted coblation adenoidectomy patients.

Coblation adenoidectomy has significant advantages over conventional adenoidectomy in terms of reduced blood loss, no post-operative residual tissue and lower pain grade on day 1 after surgery.

Surgery for chronic suppurative otitis media performed in low- and middle-income countries creates specific challenges. This paper describes the equipment and a variety of techniques that we find best suited to these conditions. These have been used over many years in remote areas of Nepal.

Extensive chronic suppurative otitis media is frequently encountered, with limited pre-operative investigation or treatment possible. Techniques learnt in better-resourced settings with good follow up need to be modified. The paper describes surgical methods suitable for resource-poor conditions, with rationales. These include methods of tympanoplasty for subtotal wet perforations, hearing reconstruction in wet ears and open cavities, large aural polyps, and canal wall down mastoidectomy with cavity obliteration. Various types of autologous ossiculoplasty are described in detail for use in the absence of prostheses. The following topics are discussed: decision-making for surgery on wet or best hearing ears, children, bilateral surgery, working with local anaesthesia, and obtaining adequate consent in this environment.

Simulation-based training has a fundamental role in medical education as it allows the learner to gain experience managing emergencies in a safe, controlled environment.

This 1-day course consisted of eight high-fidelity simulation scenarios, followed by a video-assisted debrief focusing on the technical and non-technical (communication skills, teamwork, leadership and situational awareness) aspects of managing ENT and head and neck emergencies.

Eight courses have run since June 2014. Post-course questionnaires demonstrated that candidates’ confidence scores in managing airway and head and neck emergencies increased following completion of the course (p < 0.0001).

This was the first fully immersive ENT simulation course developed in the region. The learning objectives for each scenario were mapped to the ENT Intercollegiate Surgical Curriculum Programme. Feedback from the course indicated a continued demand for this style of training, leading to its inclusion in the training calendar.

There has been little reported on the transoral reconstructive options following salvage transoral robotic surgery. This paper describes the facial artery musculomucosal flap as a method to introduce vascularised tissue to a previously irradiated resection bed.

A facial artery musculomucosal flap was used to reconstruct the lateral pharyngeal wall in 13 patients undergoing salvage transoral robotic surgery for oropharyngeal squamous cell carcinoma. Outcomes recorded include flap and donor site complications, length of stay, and swallowing and speech outcomes.

There were no immediate or late flap complications, or cases of delayed wound healing in this series. There were two facial artery musculomucosal related complications requiring surgical management: one bleed from the facial artery musculomucosal donor site and one minor surgical revision. Healing of the flap onto the resection bed was successful in all cases.

The facial artery musculomucosal flap provides a suitable transoral local flap option for selected patients undergoing salvage transoral robotic surgery for oropharyngeal malignancies.

To analyse the incidence of second primary lung cancer following treatment for laryngeal cancer and to identify risk factors for its development.

Retrospective case series.

The five-year actuarial incidence of second primary lung cancer was 8 per cent (1.6 per cent per year). This was associated with a very poor median survival of seven months following diagnosis. Supraglottic tumours were associated with an increased risk of second primary lung cancer compared to glottic tumours in both univariate (hazard ratio = 4.32, p = 0.005) and multivariate analyses (hazard ratio = 4.14, p = 0.03).

Second primary lung cancer occurs at a rate of 1.6 per cent per year following a diagnosis of laryngeal cancer, and this is associated in a statistically significant manner with supraglottic primary tumour. The recent National Lung Cancer Screening Trial suggests a survival advantage of 20 per cent at five years with annual screening using low-dose computed tomography scanning of the chest in a comparable cohort to ours. These findings have the potential to inform post-treatment surveillance protocols in the future.

To explore the role of T-helper 17 cells and their cascade in the pathogenesis of laryngeal cancer.

Prospectively, 110 consecutive patients with a suspicious laryngeal lesion were evaluated for serum levels of T-helper 17 cell related interleukins, including interleukins 23, 17A and 22, determined by enzyme-linked immunosorbent assay. The patients were divided into 2 groups after pathological evaluation: 49 patients with malignancy and 61 with benign pathology. Associations between interleukin levels and malignancy were determined via correlation analyses.

Interleukin 17A and 22 levels were significantly higher in the malignancy group than the benign lesion group. Pearson correlation analysis showed that interleukins 17A and 22 acted in a cascade, but interleukin 23 did not. According to predictive values, interleukin 17A levels were 3.87 times and interleukin 22 levels were 1.09 times more likely to be associated with laryngeal cancer. The cut-off values for predicting laryngeal cancer were 3.55 pg/ml for interleukin 17A and 119.82 pg/ml for interleukin 22.

T-helper 17 cell related interleukins are potential biomarkers that may be helpful in diagnosing laryngeal cancer. Moreover, these data may support neutralisation of T-helper 17 cell related cytokine activity, which could be an attractive strategy for treating laryngeal cancer.
