There is growing concern over a future shortfall in provision of UK otolaryngology consultants. There is a declining rate of applications to otolaryngology specialty training in the UK.

This study aimed to systematically review the literature to establish what factors influence medical students’ and junior doctors’ decision to pursue a career in otolaryngology.

Medline, Embase and PubMed databases were searched in January 2019. Additional manual reference checks of identified literature were performed.

Eleven articles were included in the review. Common factors that positively influenced the decision to pursue a career in otolaryngology were exposure to the specialty, positive role models and a good work-life balance. Lack of exposure was a consistent deterrent from pursuing a career in otolaryngology.

This review reiterates the need for greater exposure to otolaryngology in the undergraduate curriculum. In addition, mentorship for students with an interest in otolaryngology should be a priority.

Concurrent chemotherapy with radiotherapy is the standard treatment for locoregionally advanced nasopharyngeal cancer. Cetuximab can be used in the treatment of head and neck squamous cell carcinoma. However, the randomised studies that led to approval for its use in this setting excluded nasopharyngeal cancer. In the context of limited data for the use of cetuximab in nasopharyngeal cancer in the medical literature, this review aimed to summarise the current evidence for its use in both primary and recurrent or metastatic disease.

A literature search was performed using the keywords ‘nasopharyngeal neoplasm’, ‘cetuximab’ and ‘Erbitux’.

Twenty studies were included. There were no randomised phase III trials, but there were nine phase II trials. The use of cetuximab in the treatment of nasopharyngeal carcinoma has been tested in various settings, including in combination with induction chemotherapy and concurrent chemoradiotherapy, and in the palliative setting.

There is no evidence of benefit from the addition of cetuximab to standard management protocols, and there is some evidence of increased toxicity. There is more promise for its use in metastatic or locally recurrent settings. This review draws together the existing evidence and could provide a focus for future studies.

Mastoiditis is an otological emergency, and cross-sectional imaging has a role in the diagnosis of complications and surgical planning. Advances in imaging technology are becoming increasingly sophisticated and, by the same token, the ability to accurately interpret findings is essential.

This paper reviews common and rare complications of mastoiditis using case-led examples. A radiologist-derived systematic checklist is proposed, to assist the ENT surgeon with interpreting cross-sectional imaging in emergency mastoiditis cases when the opinion of a head and neck radiologist may be difficult to obtain.

A 16-point checklist (the ‘mastoid 16’) was used on a case-led basis to review the radiological features of both common and rare complications of mastoiditis; this is complemented with imaging examples.

Acute mastoiditis has a range of serious complications that may be amenable to treatment, once diagnosed using appropriate imaging. The proposed checklist provides a systematic approach to identifying complications of mastoiditis.

The evidence supporting the efficacy of antibiotic therapy in the treatment of chronic rhinosinusitis is not compelling. A limited number of studies show that the changes in the nasal microbiome in patients following drug therapy are unpredictable and variable. The evidence for the impact of oral antibiotics on the gut microbiota is stronger, possibly as a result of differences in drug distribution to various sites around the body. There are few studies on sinus mucosal and mucus levels of oral antibiotics used in the treatment of chronic rhinosinusitis. The distribution dependent effects of antibiotics on the sinonasal microbiome is unclear.

This review highlights that relative drug concentrations and their efficacy on microbiota at different sites is an important subject for future studies investigating chronic rhinosinusitis.

Acquired anterior glottic web poses a significant challenge to laryngologists given its propensity to recur following treatment, and there are a wide variety of described techniques.

A systematic review of the medical literature was undertaken in order to identify all articles pertaining to the management of acquired anterior glottic web.

Thirteen studies meeting the inclusion criteria were identified and analysed. All were retrospective series, with varying surgical techniques and outcome measures. Only two studies reported on the use of topical mitomycin C.

Mucosal graft techniques and keel placement appear to improve success rates, but both carry risks and disadvantages. Based on the available evidence, the use of topical agents such as mitomycin C cannot be recommended in the management of acquired anterior glottic web.

Machine learning algorithms could potentially be used to classify patients referred on the two-week wait pathway for suspected head and neck cancer. Patients could be classified into ‘predicted cancer’ or ‘predicted non-cancer’ groups.

A variety of machine learning algorithms were assessed using the clinical data of 5082 patients. These patients had previously been referred via the two-week wait pathway for suspected head and neck cancer to two separate tertiary referral centres in the UK. Outcomes from machine learning classification were analysed in comparison to known clinical diagnoses.

Variational logistic regression was the most clinically useful technique of those chosen to perform the analysis and patient classification; the proportion of patients correctly classified as having ‘non-cancer’ was 25.8 per cent, with a false negative rate of 1 out of 1000.

Machine learning algorithms can accurately and effectively classify patients referred with suspected head and neck cancer symptoms.

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.

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.

The indications for expanded endoscopic transnasal approaches continue to increase, with more complex skull base defects needing to be repaired. This study reviews the management of large anterior skull base defects with opening of the sellar diaphragm.

A prospective analysis of endonasal endoscopic surgery carried out at Son Espases University Hospital between January 2013 and December 2018 was performed. The analysis included only the cases with a significative intra-operative cerebrospinal fluid leak. In all cases, reconstruction was performed by combining the gasket seal technique with a pedicled mucosal endonasal flap.

Twenty-eight patients were included. The mucoperiosteal nasoseptal flap, the lateral wall flap and the middle turbinate flap were used in 13, 8 and 7 patients, respectively, combined with the gasket seal technique. One case of post-operative cerebrospinal fluid leak was observed (3.57 per cent).

The combination of a gasket seal with an endonasal mucosal flap is an excellent technique for repairing large anterior skull base defects.

To examine the relationship between the therapeutic effect of intratympanic methylprednisolone perfusion and histone acetylation in refractory sudden sensorineural hearing loss.

Thirty-four refractory sudden sensorineural hearing loss patients were enrolled and treated with intratympanic methylprednisolone perfusion. Pure tone average, acetylated histone H3, acetylated histone H4 and histone deacetylase 2 (HDAC2) were measured in peripheral blood mononuclear cells before and after intratympanic methylprednisolone perfusion. Sixteen healthy volunteers were recruited to obtain normal reference values.

Pure tone average in sudden sensorineural hearing loss patients improved from 84.14 ± 13.54 dB to 73.56 ± 18.45 dB after intratympanic methylprednisolone perfusion. Up-regulations in HDAC2 protein level, and down-regulations in histone H3 and H4 acetylation were observed in the intratympanic methylprednisolone perfusion sensitive group (pure tone average gain of 15 dB or more), while no significant changes were observed in the intratympanic methylprednisolone perfusion insensitive group (pure tone average gain of less than 15 dB).

Intratympanic methylprednisolone perfusion can improve hearing in a considerable number of refractory sudden sensorineural hearing loss patients. The therapeutic effect is closely related to reduced histone acetylation.

To report device failures, audiological signs and other reasons for revision cochlear implant surgery, and discuss indications for revision surgery.

Revision procedures between November 1997 and August 2017 were retrospectively analysed. Over 20 years, 2181 cochlear implant operations were performed, and 114 patients underwent 127 revision operations.

The revision rate was 4.67 per cent. The full insertion rate for revision cochlear implant surgery was 88.2 per cent. The most frequent reasons for revision surgery were: device failure (59 per cent), wound breakdown (9.4 per cent) and electrode malposition (8.7 per cent). The device failure rate was: 2.78 per cent for Advanced Bionics, 1.82 per cent for Cochlear and 5.25 per cent for Med-El systems. The number of active electrodes was significantly increased only for Med-El devices after revision surgery. The most common complaints among 61 patients were: gradually decreased auditory performance, sudden internal device shutdown and headaches.

The most common reason for revision surgery was device failure. Patients should be evaluated for device failure in cases of: no hearing despite appropriate follow up, side effects such as facial nerve stimulation, and rejection of speech processor use in paediatrics. After revision surgery, most patients have successful outcomes.

This study aimed to analyse the common presentations and treatment outcomes in cases involving nasal foreign bodies.

A retrospective study was carried out over three years, from January 2014 to December 2017. Patient biodata, clinical presentation, nasal foreign body type and management outcome data were obtained from the medical records and analysed.

A total of 341 cases were analysed. The average patient age was 3.7 ± 1.2 years (range, 1–19 years).Of the nine cases involving button batteries, septal perforation was initially seen in four cases and three cases had subsequent septal perforation.

Only button battery nasal foreign bodies were associated with increased septal perforation. Use of physiological seawater nasal spray was found to reduce the likelihood of septal perforation. Most nasal foreign bodies could be removed under local anaesthesia.

Concha bullosa may be associated with paranasal sinus infections and nasal obstruction. Middle concha mucosa membranes have olfactory neurofibrils. This study investigated the impact of routinely used concha bullosa surgery techniques – crushing and lateral laminectomy – on nasal and olfactory functions.

Forty-three adult patients who had undergone surgery for a symptomatic concha bullosa completed the odour test, nasal obstruction visual analogue scale, 22-item Sino-Nasal Outcome Test, and peak nasal inspiratory flow test, pre-operatively and three months post-operatively. The pre- and post-operative results within and between the two treatment groups were compared.

Intragroup comparison of mean pre- versus post-treatment changes revealed statistically significant findings for the nasal obstruction visual analogue scale, Sino-Nasal Outcome Test, peak nasal inspiratory flow and olfaction tests (all p < 0.05). However, there were no statistically significant changes when comparing the scores between the groups (intergroup comparison).

Lateral laminectomy and crushing in concha bullosa surgery have no negative effects on olfactory function. Concha bullosa surgery provides positive outcomes regarding nasal complaints in symptomatic patients.

This study aimed to assess the potential role of pneumatisation of the mastoid and its communicating air cells in the development of middle-ear barotrauma in aircrew members.

Seventy-nine aircrew members (158 ears) underwent temporal computed tomography. All were assessed before flying by clinical examination and audiology evaluation, followed by post-flight examination to detect barotrauma.

Aircrew members’ ears were divided into 3 groups based on barotrauma and temporal bone pneumatisation: 33 ears with barotrauma and temporal bone pneumatisation of 71 cm3 or greater (group A); 12 ears with barotrauma and temporal bone pneumatisation of 11.2 cm3 or lower (group B); and 113 ears with no barotrauma (group C). Mean pneumatisation volumes were 91.05 cm3, 5.45 cm3 and 28.01 cm3 in groups A, B and C, respectively. A direct relationship was observed between volume of temporal bone pneumatisation of 71 cm3 or greater and barotrauma grade.

Pneumatisation volume of the mastoid and its communicating air cells that ranges from 11.3 cm3 to 70.4 cm3 serves as a reliable predictor of the avoidance of middle-ear barotrauma associated with flying in aircrew members who have normal resting middle-ear pressure and good Eustachian tube function.

Silver nitrate cautery and bipolar electrocautery are commonly used in the treatment of epistaxis. Currently, there are no recommendations on optimum contact times or power for nasal cautery. ENT consultant practice in the UK has not previously been evaluated.

This study examined the burn depth associated with silver nitrate (75 per cent concentration) cautery and bipolar electrocautery on porcine septum samples, using varying contact times and power. ENT consultants completed a survey evaluating their practice.

ENT consultant practice of nasal cautery was shown to vary widely. Silver nitrate cautery with a contact time of less than 30 seconds does not cause a full thickness burn. The findings lend some support to bilateral cauterisation with silver nitrate. Bipolar electrocautery should be set at lower than 10 W and with a contact time of less than 4 seconds to reduce the risk of complications associated with a full thickness burn.
