Various vestibular stimuli, including air-conducted sound (ACS), bone-conducted vibration (BCV), and galvanic vestibular stimulation (GVS), can be used to elicit vestibular-evoked myogenic potential (VEMP). VEMP obtained from the sternocleidomastoid (SCM) muscle is called cervical VEMP (cVEMP), while that recorded at extraocular muscles is termed ocular VEMP (oVEMP). cVEMP was first recognized as fundamental in determining the sacculo-collic reflex (SCR) pathway in the mid-1990s. In the mid-2000s, oVEMP was successfully recorded and emerged as the basis for a promising examination for evaluating the integrity of the vestibulo-ocular reflex (VOR) pathway...

OBJECTIVES: Unilateral tinnitus must be investigated with an IAM MRI to rule out a rare but important finding of a cerebello-pontine angle lesion. A streamlined pathway was designed to uniquely enable GPs to make direct and concurrent referrals for an IAM MRI alongside an audiology-led one-stop tinnitus clinic. The primary aim was evaluating the efficacy of the streamlined pathway. The secondary aim was to identify defect measures and associated costs. Design A prospective, experimental non-randomised control study with retrospective controls was used...

The postcricoid space and pyriform sinus are difficult to completely display under routine laryngoscopy examination. We present the results obtained from 50 patients who were randomly recruited to receive a laryngoscopy examination via a routine, Valsalva manoeuvre combined with anterior cervical skin traction (V-ACST), followed by a Valsalva manoeuvre combined with the modified Killian method (V-MK). The routine method is not suitable for displaying the postcricoid space. In general, both the V-ACST and V-MK displayed the postcricoid space and pyriform sinus very well...

OBJECTIVES: The main purpose of this study was to evaluate flap size and flap design of skin islands in myocutaneous serratus anterior free flaps (SAFFs) in fresh cadavers and to further investigate whether myocutaneous SAFFs are suitable flaps for pharyngeal reconstruction after laryngopharyngectomy. METHODS: Dissection and injection of methylene blue was performed in 20 hemithoraces of 13 fresh cadavers to evaluate flap size and location of skin islands. Based on these preclinical data, we performed pharyngeal reconstruction with myocutaneous SAFF in 5 patients after laryngopharyngectomy...

OBJECTIVES: Subjective visual vertical (SVV) is a simple, quick and reliable test for measuring utricular function. The literature on the effects of fundamental demographic variables such as age and gender on SVV is inconclusive and should be supported by research with larger samples. The aim of the present study was to determine the influences of age, gender and geometric pattern of visual image on SVV among healthy adults. STUDY DESIGN: This study employed a repeated measures design...

Direct visualisation of the upper aerodigestive tract is a fundamental skill for ENT surgeons. Rigid endoscopes themselves have seen little transformation since they were first developed for gastroscopy by Kussmaul in 18681 . In an era of ultra high definition and 3D technology, a straight, rigid metal tube with adjoining light source carrier to inspect mucosal surfaces up to 40cm from the surgeon's eye could benefit from updating. In our department, we favour the use of the video-laryngoscope, specifically the C-MAC system from Karl Storz...

Between January 2006 and December 2015, 320 patients with vocal fold paralysis (VFP) were identified in Kuopio University Hospital, Finland. The overall annual incidence rate of VFP was 11.4 per 100 000 inhabitants (95% confidence interval 10.1-12.8). The most common etiologies of VFP were iatrogenic (50.6%), idiopathic (21.6%), and neoplasm (14.7%). The incidence of VFP during surgical procedures was 5.2% in thyroid surgery, 4.3% in parathyroid surgery, 16.6% in esophageal surgery, 5.6% in mediastinoscopy, 4% in non-cardiac surgery through sternotomy, 3...

In suspension microlaryngoscopy, the endotracheal tube, which hampers the vision of the subglottic plane, may disturb the surgery. Transnasal Humidified Rapid-Insufflation Ventilatory Exchange (THRIVE) provides effective aventilatory mass flow under deep sedation and seems an interesting approach to operate without endotracheal tube. The objective is to evaluate the indications, the technique and the failures of THRIVE in laryngeal surgery. This prospective study included 19 patients over the age of 18, that overwent laryngeal surgery under laryngosuspension...

Adenoidectomy is a commonly performed paediatric ear nose and throat operation. It is indicated in children for the treatment of nasal obstruction, recurrent otitis media with effusion, and sleep-disordered breathing. Conventionally the procedure was performed by cold curettage, with a higher rate of persistent postoperative bleeding. Monopolar suction diathermy adenoidectomy shows improved haemostasis with reduced intraoperative blood loss and postoperative bleeding. This article is protected by copyright...

We read with interest the recent article titled 'Expression of 15-lipoxygenase-1 in Merkel cell carcinoma is linked to advanced disease'. Frochman-Frana and colleagues concluded that ALOX15 expression is seen in primary MCC tumor samples as well as lymph node metastasis samples. Primary tumors of metastatic MCC had a higher expression rate of ALOX15 compared to samples without metastatic disease, providing evidence in support of ALOX15's association with cancer development.

Definitive diagnosis of allergic fungal sinusitis is confirmed by pathologists postoperatively. We aimed at identifying preoperative predictive factors for allergic fungal sinusitis (AFS) diagnosis in order to support the surgical strategy that requires a complete surgical debridement of the fungal material, thus differing from classical endoscopic surgery for chronic rhinosinusitis (CRS). The confirmation of systemic corticotherapy indication and its rapid postoperative introduction reduces the risk of relapse...

Approximately 9% to 42% of people with head and neck cancer (HNC) belong to the intermediate-risk (IR) class. The benefit of postoperative radiotherapy (PORT) may not be uniform across various patient subgroups of IR-HNC. Our 134-patient experience retrospectively explores the issue of which IR-HNC patient subset (T3-T4 or nodal metastases without extracapsular spread/ECS) may benefit from PORT. Particular attention should be paid to a more intensive adjuvant regimen of chemoradiotherapy for the nodal metastases ECS-free patient cohort because of the poorer disease-free survival after PORT alone that was observed in the present study...

Inner ear malformations were significantly associated with a facial nerve anomaly in 11% of cases. The most frequent malformations associated with facial nerve anomalies are common cavity and cochlear hypoplasia. Middle ear malformations, especially the hypoplastic stapes, were frequently associated with an inner ear malformation. Although essential, pre-operative imaging does not allow detection of all facial nerve anomalies. During cochlear implantation in malformed cochlea, we recommend the use of facial nerve monitoring when accessing the round window niche...

Workforce planning is essential to ensure enough doctors, with the necessary skills and training, are available to meet the demands on the health service. This task is challenging within the NHS due to the time period over which forecasts are made and the complexity of healthcare delivery.The aim of this study was to identify the number of Ear, Nose and Throat (ENT) consultants, trainees, non-consultant-grade doctors and vacancies across England, Scotland and Wales and compare with previous data from England recorded in 2014 and 2010...

18F FDG PET is superior to other imaging techniques in revealing residual laryngeal cancer after radiotherapy. Unfortunately, its specificity is low, due to FDG uptake in inflammation and in anaerobic conditions. PET imaging with the amino acid-based radiopharmaceutical C11-methionine (MET) should be less influenced by post-radiation conditions. The aim of this study was to investigate the potential of MET in diagnosing recurrent laryngeal cancer after radiotherapy as compared to 18F-FDG. METHODS: Forty-eight patients with a clinical suspicion of local residual disease at least three months after completion of radiotherapy or chemoradiotherapy for a T2-4 laryngeal carcinoma, along with an indication for direct laryngoscopy, were included...
