Article
Objectives: To investigate the combined effect of changing pulse shape and grounding configuration to manage facial nerve stimulation (FNS) in cochlear implant (CI) recipients. Patients: Three adult CI recipients with severe FNS were offered a replacement implant when standard stimulation strategies and programming adjustments did not resolve sy...

Objective: To analyse the epidemiology of otosclerosis in a British cohort collected between 2011 and 2017. Design: Retrospective cohort study. Setting: Five UK ENT Departments. Patients: Patients with surgically confirmed otosclerosis. Main outcome measures: Questionnaire data documented family history of otosclerosis, age of onset, medic...
Article
Objective: To examine inter-aural hearing preservation results in children undergoing simultaneous bilateral cochlear implantation (CI). Methods: Retrospective case review in tertiary referral centre. All children undergoing simultaneous bilateral CI between January 2013 and June 2014 (18 months). Patients eligible for inclusion in the study had pr...
Article
Objective To report a novel management strategy for mixed hearing loss in advanced otosclerosis. Methods A 50-year-old male was referred to St Thomas’ Hearing Implant Centre with otosclerosis; he was no longer able to wear conventional hearing aids because of recurrent otitis externa. The patient underwent short process incus vibroplasty (using th...
Article
Objectives This paper reports three cases of severe post-stapedectomy granuloma, emphasising the variable presentation of this devastating complication and the challenges of its management. Methods A retrospective review was conducted of three cases of post-stapedectomy granuloma requiring surgical debulking between 2010 and 2015. Clinical symptom...
Article
Objective: To present the management strategy and outcomes for our series of superior semicircular canal dehiscence syndrome (SSCDS) patients. Study design: Retrospective cross-sectional study. Setting: Tertiary referral center. Patients: Thirty-seven consecutive patients referred from June 2011 to January 2015. Diagnosis of SSCDS based on p...
Article
Objective and importance: In children with X-linked deafness, cochlear malformations challenge the implant surgeon to avoid electrode insertion into the internal auditory meatus and prevent a continuous cerebrospinal fluid (CSF) leak. We describe our experience of cochlear implantation (CI) in two children with profound hearing loss secondary to X...

Article
Full-text available
Otosclerosis is a relatively common heterogenous condition, characterised by abnormal bone remodelling in the otic capsule leading to fixation of the stapedial footplate and an associated conductive hearing loss. Although familial linkage and candidate gene association studies have been performed in recent years, little progress has been made in id...
Article
Objective: To assess cochlear implant (CI) outcomes, and factors affecting outcomes, for children with aplasia/ hypoplasia of the cochlea nerve. We also developed a new grading system for the nerves of the internal auditory meatus (IAM) and cochlea nerve classification. Study design: Retrospective patient review. Setting: Tertiary referral hos...
Article
Objective: In 1977, Tjellstrom et al. used the concept of osseointegration and implanted patients with a titanium screw as part of the first bone-anchored hearing solution. Despite good hearing outcomes with the percutaneous device, there has been a drive for the development of transcutaneous bone conduction systems because of soft tissue complicat...
Article
Objectives The aim of this study was to assess if large vestibular aqueduct syndrome (LVAS), with the increase in perilymphatic pressure, affects impedance changes over time with different types of Cochlear® implant electrode arrays Contour, Straight, and CI 422. To report speech perception outcomes for these cochlear implant recipients. Methods Re...

The aim of this study is to determine the incidence and causes for cochlear explantation/re-implantation in children as a retrospective case review in a Quaternary paediatric Cochlear Implant (CI) Centre. The subjects included in the study were Paediatric CI patients requiring cochlear explantation/re-implantation. Outcome measurements were inciden...
Article
We would like to report a novel method for the treatment of obstructive sleep apnoea (OSA), upper airways resistance syndrome (UARS) and snoring in selected patients. Continuous positive airway pressure1 (CPAP) is the gold standard treatment for OSA and there are a number of other devices such as mandibular advancement devices2 (MAD) and surgical i...
Article
The London Postgraduate School of Surgery has increased its minimum requirement for workplace-based assessments (WBAs) from 40 to 80 per annum. Specialty trainees were alerted to this increase by email in March 2012. This has been the requirement for core trainees since October 2011. In response to this increase for specialty trainees, an online su...
Article
The free fibular flap is commonly used for mandibular reconstruction because of its length, consistent blood supply, and relative ease of harvest. The bone has been shown to maintain mass over time, which confers a potential advantage over other osseous flaps. We know of no published papers on changes in height of fibular bone in patients treated f...
Article
Objectives Determine the incidence and risk factors for cochlear re-implantation in children. Methods Retrospective case review in a quaternary pediatric cochlear implant (CI) center. Subjects studied: Pediatric CI patients requiring cochlear re-implantation. Interventions: Cochlear explantation/re-implantation. Outcome measures: Etiology and timi...

In the UK, stapes surgery is performed almost universally under general anaesthesia. In 1984 there was consensus that local anaesthesia should be the technique of choice in stapes surgery. Despite reports of successful use of local anaesthesia for middle ear surgery, this is still not widely accepted practice in the UK. We describe the senior autho...
Article
There is a paucity of studies on patient-reported outcome measures in adult tonsillectomy. Our aim was to add to the body of health-related quality of life (HRQOL) evidence on adult tonsillectomy at a time when this intervention is being branded a low priority treatment in the United Kingdom (UK). We designed a prospective questionnaire study that...
Article
Surgical emphysema is a recognised complication of percutaneous tracheostomy (PT) and it has been shown that this is a particular problem when a fenestrated tracheostomy tube is initially used in patients receiving positive pressure ventilation. The recently published ‘Standards for the care of adult patients with a temporary tracheostomy’ produced...
Article
In the English speaking literature there is very little evidence demonstrating safe and effective tympanomastoid day case surgery in pediatric practice. At a time when there is ongoing pressure for trusts to meet financial government targets and our care provision revolves around a patient centred approach, could otolaryngologists perform more pedi...
Article
Magnetic resonance imaging (MRI) is recognised as the "Gold Standard" investigation for symptoms pertaining to the inner ear and detection of retro-cochlear pathology. There is still no accurate clinical predictor for cerebellopontine angle lesions and increasingly more normal scans are being performed. With constantly increasing demands on ENT out...

Cutaneous manifestations of common viral pathogens or disease processes more common in immunocompromised individuals need to be considered when assessing patients with unusual clinical presentations. To our knowledge this is the first published case of severe nasal herpes simplex infection in an immunocompetent individual. A 27-year-old Burmese wom...
