This study compared the performance of two new bone-anchored hearing aids with older bone-anchored hearing aids that were not fully digital.

Fourteen experienced bone-anchored hearing aid users participated in this cross-over study. Performance of their existing bone-anchored hearing aid was assessed using speech-in-noise testing and questionnaires. Participants were then fitted with either a Ponto Pro or a BP100 device. After four weeks of use with each new device, the same assessments were repeated.

Speech-in-noise testing for the 50 per cent signal-to-noise ratio (the ratio at which 50 per cent of responses were correct) showed no significant differences between the Ponto Pro and the BP100 devices (p = 0.1) However, both devices showed significant improvement compared with the participants' previous bone-anchored hearing aid devices (p < 0.001). There were no significant differences between the two new devices in the questionnaire data.

Both fully digital bone-anchored hearing aids demonstrated superior speech processing compared with the previous generation of devices. There were no substantial differences between the two digital devices in either objective or subjective tests.

To determine the prevalence and characteristics of various diagnostic groups amongst patients referred to ENT practices with the primary complaint of dizziness.

A prospective, observational, multicentre study.

Consecutive patients presenting with dizziness to the participating ENT practices were enrolled. Seven ENT specialists at three clinics participated.

Benign paroxysmal positional vertigo was diagnosed in 53.3 per cent of the 1034 study patients. Fifty-nine per cent of these experienced night-time awakening with dizziness, which was a significant proportion in comparison to the other diagnostic groups. Benign paroxysmal positional vertigo was the most frequent diagnosis in all age groups, including those over 70 years.

In this study of patients referred to ENT for dizziness, benign paroxysmal positional vertigo was the dominant diagnostic entity, in all age groups and overall. All clinicians in contact with dizzy patients must consider benign paroxysmal positional vertigo, especially in the elderly.

The protein 14-3-3 sigma plays a role in cell cycle arrest by sequestering cyclin-dependent kinase 1 cyclin B1 complexes, as well as cyclin-dependent kinases 2 and 4, hence its definition as a cyclin-dependent kinase inhibitor. However, the nature of the interaction between these biological markers in nasopharyngeal carcinoma is unknown. This study aimed to investigate whether altered expression of these markers contributes to nasopharyngeal carcinogenesis.

The study population consisted of 30 nasopharyngeal carcinoma patients and 10 patients without nasopharyngeal carcinoma. The nasopharyngeal carcinoma cell lines TW02, TW04 and Hone-1 were also assessed. We analysed levels of messenger RNA and protein for the p16 gene and the 14-3-3 sigma, Epstein–Barr nuclear antigen 1, and cyclin-dependent kinase 2 and 4 proteins, in nasopharyngeal carcinoma tissue specimens and cell lines and in normal nasopharyngeal tissue.

Protein and messenger RNA levels for cyclin-dependent kinase 2 and Epstein–Barr nuclear antigen 1 were significantly higher in nasopharyngeal carcinoma compared with normal tissue, while levels of cyclin-dependent kinase 4 generally were not; results for 14-3-3 sigma varied. Nasopharyngeal carcinoma patients had diminished p16 gene expression, compared with normal tissue.

Levels of cyclin-dependent kinase 2 and Epstein–Barr nuclear antigen 1 were significantly higher in nasopharyngeal carcinoma than in normal tissue, while p16 gene expression was diminished. These three proteins may contribute to nasopharyngeal carcinogenesis.

This study aimed to investigate the validity and feasibility of cervical oesophagostomy as a treatment for patients with severe dysphagia after radiotherapy for nasopharyngeal carcinoma.

The study retrospectively analysed the clinical data, symptoms, physical signs, treatment and outcomes of 12 patients treated with cervical oesophagostomy for severe dysphagia after radiotherapy for nasopharyngeal carcinoma, from 2006 to 2010.

In all 12 cases, the oesophageal stoma remained stable, without any complications such as pharyngeal fistula or inflammation. No oesophageal stricture or granuloma growth was observed. All patients reported significant improvement in their nutritional status and quality of life after the oesophagostomy surgery.

Cervical oesophagostomy is a valid and feasible method of treating severe dysphagia following radiotherapy for nasopharyngeal carcinoma. Oesophagostomy shows specific advantages over nasogastric tubing, gastrostomy and jejunostomy. Patients' nutrition and quality of life can be improved significantly if cervical oesophagostomy is executed in a timely fashion, especially in cases with severe trismus and multiple radiation-induced cranial nerve palsies unresponsive to rehabilitation.

We aimed to investigate the diagnostic accuracy of contact endoscopy in evaluating oral and oropharyngeal mucosal lesions.

Between January 2010 and December 2011, 34 patients with lesions of the oral and oropharyngeal mucosa were enrolled in the study. Comparison between initial contact endoscopy results and ‘gold standard’ tissue biopsy was undertaken.

Nine patients had histologically confirmed squamous cell carcinoma, 2 had carcinoma in situ, 3 had dysplastic lesions and 20 patients had various benign lesions. Contact endoscopy demonstrated sensitivity and specificity of 89 and 100 per cent respectively in the evaluation of malignant lesions. Benign lesions were correctly categorised in 50 per cent of cases (10/20). The video images from contact endoscopy could not be interpreted in six cases.

Contact endoscopy demonstrates high sensitivity and specificity in the imaging of malignant lesions with reduced reliability in the evaluation of benign lesions. Significant shortcomings also exist in the design of current technology that we believe represent a significant barrier to the reliable collection of useful video data.

Laryngeal cancer patients who continue to smoke after treatment are at an elevated risk of mortality and morbidity. This study aimed to identify factors associated with continued tobacco use following treatment in patients with laryngeal cancer.

A smoking behaviour questionnaire, a self-report measure, was sent to 112 patients who were diagnosed with laryngeal cancer during 2006–2011 at the Brighton and Sussex University Hospitals, Brighton, UK. Patient demographics, tumour and treatment-related variables, comorbidity and socio-economic status were obtained from the medical records.

Eighty-one per cent of patients responded to the survey; 22 per cent of these reported continued tobacco use after treatment. Treatment modality was found to be a predictor of post-therapeutic smoking (odds ratio: 4.9, p = 0.01); patients who received less invasive therapy (transoral laser microsurgery) were more likely to smoke after treatment.

The findings of this preliminary study suggest that treatment modality influences smoking behaviour in patients with laryngeal cancer, which may have important implications for the design of anti-smoking interventions.

Post-operative facial palsy is the most important potential complication of parotid surgery for benign lesions. The published prevalence of facial weakness is up to 57 per cent for temporary weakness and up to 7 per cent for permanent weakness. We aimed to identify potential risk factors for post-operative facial palsy.

One hundred and fifty patients who had undergone parotid surgery for benign disease were retrospectively reviewed. Tumour factors (size, location and histopathology), patient factors (age and sex) and operative factors (operation, surgeon grade, surgeon specialty and use of intra-operative facial nerve monitoring) were all analysed for significant associations with post-operative facial palsy.

The overall incidence of facial palsy was 26.7 per cent for temporary weakness and 2.6 per cent for permanent weakness. The associations between facial palsy and all the above factors were analysed using Pearson's chi-square test and found to be non-significant.

These outcomes compare favourably with the literature. No significant risk factors were identified, suggesting that atraumatic, meticulous surgical technique is still the most important factor affecting post-operative facial palsy.

New surgical techniques and devices have been described that decrease post-tonsillectomy morbidities. This study aimed to compare the two most popular tonsillectomy techniques.

Forty children underwent tonsillectomies using both the thermal welding and cold dissection techniques. In each patient, one side was removed with thermal welding and the other was removed with cold dissection.

There was a significant decrease in intra-operative blood loss, and the mean operation time was significantly lower on the thermal welding side compared with the cold dissection side. On the cold dissection side, tissue healing (i.e. the rate of complete tissue healing) was better and less pain was reported compared with the thermal welding side. However, there were no significant differences between the two techniques in terms of throat pain scores on the 1st, 3rd or 14th day post-operatively, or tissue healing scores on any of the post-operative days assessed.

Cold dissection resulted in better tissue healing and lower pain scores than thermal welding, but thermal welding was associated with less intra-operative blood loss and lower mean operation time than cold dissection.

First bite syndrome is a condition characterised by severe facial pain brought on by the first bite of each meal. This can severely affect the patient's ability to eat.

We present a 70-year-old woman for whom we performed a laser ablation of the left ear tympanic plexus, as treatment of first bite syndrome. A permeatal approach was used to raise a tympanomeatal flap. The tympanic plexus was identified on the promontory and a 4 mm2 area of the plexus was ablated using CO2 laser. The flap was repositioned and a dressing was placed with topical antibiotics.

At two-month follow up, there was full resolution of the patient's symptoms.

First bite syndrome carries a high morbidity; treatment options are variable, and often unsuccessful. We describe the first documented case of laser tympanic plexus ablation, with a very effective initial response. This procedure represents a useful therapeutic option for first bite syndrome.

It is common for ENT specialists to be called to neonatal intensive care units to assess neonates with suspected laryngomalacia. At Addenbrooke's Hospital, Cambridge, UK, it is standard practice to initially try to assess the larynx whilst the patient is awake. This can cause the patient to cry and become irritable, and can induce worry in the parents. A literature search revealed that numerous procedures have been successfully performed on neonates and infants whilst they were being pacified.

This paper describes various procedures where pacification has been used effectively. Furthermore, it reports a pacification technique developed for per-oral flexible laryngoscopy in awake neonates and infants.

Tracheostomies are a common procedure within the specialties of otolaryngology and intensive care. The ENT department at Monklands Hospital has developed the position of tracheostomy clinical nurse specialist to improve the management of tracheostomy patients. There is evidence to support the development of a multidisciplinary team for the management of tracheostomy patients following intensive care unit treatment; however, the creation of a specific tracheostomy clinical nurse specialist position has not been widely endorsed in the literature.

This paper describes the role of the tracheostomy clinical nurse specialist, advocating this position within the multidisciplinary team.

To describe a case of bilateral superior and posterior semicircular canal dehiscences, and the use of a unilateral transmastoid approach to address both right-sided defects simultaneously.

In a patient with right-sided hyperacusis, bilateral dehiscence of both the superior and the posterior semicircular canals was identified, located adjacent to the common crus, together with a right-sided, anterosuperiorly positioned sigmoid sinus and a high-riding jugular bulb. Results for audiography and cervical vestibular evoked myogenic potential testing were consistent with right-sided semicircular canal dehiscence. At surgery, a right-sided transmastoid approach provided access to plug both defects simultaneously, following posterior mobilisation of the sigmoid sinus. The patient's hyperacusis was completely resolved, with a 10–30 dB improvement in his right ear air conduction hearing, without decrement in bone conduction.

In properly selected patients, a transmastoid approach can be used to effectively manage superior semicircular canal dehiscence and posterior semicircular canal dehiscence simultaneously. Pre-operative computed tomography is recommended to evaluate the dehiscence sites and to identify complicating vascular anatomy.

To describe an unusual cause for hearing loss in an adult.

A 37-year-old man presented with a year's history of right-sided hearing loss. He had no history of trauma, or local or systemic infection. He was otherwise well, took no medication and had no allergies. He had a two-year history of low back pain. On examination, he had a retracted right tympanic membrane with no perforation, and a middle-ear effusion. Nasendoscopy was normal. Examination of other systems was unremarkable. Computed tomography of the temporal bones with contrast demonstrated a large, right, intra-cerebral internal carotid artery aneurysm compressing the eustachian tube. After a balloon occlusion test, he underwent endovascular occlusion of the parent vessel. He made a good post-operative recovery. A subsequent abdominal ultrasound excluded an abdominal aneurysm as a cause of his low back pain. His hearing had not improved three days post-operatively, and was to be formally assessed and monitored in the clinic.

A carotid aneurysm is a rare cause of eustachian tube compression but must be considered in the differential diagnosis of conductive hearing loss. Aneurysms may have systemic causes, and their presence in other systems should be excluded as they may be multiple.

We report a novel, computed tomography guided treatment for autophony associated with a patulous eustachian tube.

Case report and literature review of the management of patulous eustachian tube.

A 36-year-old woman presented with disabling autophony. Otoscopic examination revealed a poorly mobile right tympanic membrane. High resolution temporal bone computed tomography excluded superior semicircular canal dehiscence. The patient was diagnosed with patulous eustachian tube but failed to achieve therapeutic benefit from conventional endoscopic placement of a silicone elastomer suspension implant adjacent to the eustachian tube. Subsequently, she underwent further silicone elastomer suspension implant placement via a trans-cutaneous, computed tomography guided approach. The patient achieved prompt symptomatic relief and remained symptom-free at six-month follow up.

This is the first published description of treatment of patulous eustachian tube using a computed tomography guided, trans-cutaneous approach. It serves to highlight to otolaryngologists the fact that computed tomography guided treatment of patulous eustachian tube may control disabling symptoms in patients who have failed to respond to convention endoscopic management.

We report a missed case of otosyphilis presenting as otic capsule lucencies on temporal bone computed tomography.

A 58-year-old woman presented with a 15-year history of bilateral, mixed hearing loss together with otic capsule lucencies, subsequently confirmed as otosyphilis. A literature review of otosyphilis was undertaken based on a PubMed search of studies published between 1988 and 2012, using the key words ‘otosyphilis’, ‘otodystrophy’, ‘otic capsule lucencies’ and ‘luetic osteitis’.

Although rare, otosyphilis is important to recognise as it is one of the few treatable causes of deafness when diagnosed early. The differentiating computed tomography features of luetic osteitis (otosyphilis) of the temporal bone have only rarely been described. We emphasise how these imaging features can be used to distinguish the rare but treatable condition of luetic osteitis from other, more common conditions with similar imaging findings.

Maxillary sinus atelectasis is a form of chronic rhinosinusitis of uncertain aetiology. Previously, the conventional treatment for this condition has been standard endoscopic surgery. There are no reports in the literature of successful treatment using balloon sinuplasty.

A case of a patient with right maxillary sinus atelectasis is presented, who was treated using the balloon sinuplasty technique.

The patient's right maxillary sinus atelectasis was successfully treated using balloon sinuplasty. Three-month follow-up evaluation documented retention of the remodelled form of the uncinate process, and of maxillary sinus os patency.

This is the first report of successful use of the balloon sinuplasty technique for the treatment of maxillary sinus atelectasis. Follow up demonstrated resolution of the underlying pathophysiology. Further study of the balloon sinuplasty technique for the treatment of maxillary sinus atelectasis is required to determine whether it has widespread applicability, given the current standard treatment.

We report three-dimensional fluid-attenuated inversion recovery magnetic resonance imaging findings in a patient with relapsing polychondritis.

Case report.

A 76-year-old woman initially presented with bilateral auricular swelling together with dyspnoea. Three months later, she experienced left hearing loss and recurrent vertigo. A biopsy of the auricle was performed and relapsing polychondritis was diagnosed. The patient underwent three-dimensional fluid-attenuated inversion recovery magnetic resonance imaging 4 hours after intravenous injection of a standard dose of gadolinium. Gadolinium enhancement was visible throughout the vestibule and the endolymphatic space could not be visualised, suggesting breakdown of the blood–labyrinth barrier.

This is the first radiological report to demonstrate breakdown of the blood–labyrinth barrier in a case of relapsing polychondritis with inner ear impairment.

Zenker's diverticulum is a propulsion diverticulum in the pharynx. Current practice for the management of symptomatic pharyngeal pouches includes endoscopic pharyngeal stapling, performed trans-orally, and external approaches via a cervical incision. There is no published recommendation on how to approach diverticula with extension into the mediastinum, which may not be adequately treated with the above methods.

We describe two cases in which thoracoscopic mobilisation of Zenker's diverticulum was performed using video-assisted thoracoscopic surgery together with traditional transcervical mobilisation and excision of the pouch. This allowed safe surgical access to the inferior limit of the pouch, and delivery of the sac into the neck incision following division of any inferior adhesions (to the great vessels in one case).

In the first report of this technique, we describe a thorough, safe method of dissecting large diverticula that extend into the mediastinum, which minimises the risk to mediastinal structures.
