For centuries, the tympanum has remained the only visible structure of the organ of hearing. This study aimed to trace the understanding of the tympanic membrane from antiquity to the early twentieth century.

A review was conducted of primary and secondary historical and scientific literature describing the tympanic membrane anatomy.

Although ancient polymaths sensed that sounds were vibrations that could spread in the air and be perceived by the hearing organ, there were numerous misconceptions about the tympanum until human dissections performed during the Renaissance. The tympanum was correctly described only centuries later when technological advances enabled otologists to understand it as a fundamental part of the hearing organ.

The tympanic membrane history reflects key stages in medical knowledge; limited for centuries, a great technological leap was possible in the nineteenth century, contributing to the emergence of otologists and laying the foundations of modern otology.

The aim of this study was to identify any relationship between hearing loss and mild cognitive impairment.

This was a systematic review and meta-analysis of randomised controlled trials conducted using Medline and the Cochrane Library up to 24 June 2020. Prospective, cohort and cross-sectional, and observational studies that reported on the relationship between mild cognitive impairment and hearing loss were included.

A total of 34 studies reporting data on 48 017 participants were included. Twenty-three studies observed a significant association between hearing loss and mild cognitive impairment. The pooled risk ratio across all studies of prevalence of mild cognitive impairment in people with hearing loss was 1.44 (random-effects; 95 per cent CI = 1.27–1.64; p < 0.00001; I2 = 0 per cent). Significantly more people with mild cognitive impairment had peripheral hearing loss compared with those without (risk ratio, 1.40 random-effects; 95 per cent CI = 1.10–1.77; p = 0.005; I2 = 0 per cent). When the incidence was studied, significantly more people with peripheral hearing loss had mild cognitive impairment compared with those without (risk ratio = 2.06 random-effects; 95 per cent CI = 1.35–3.15; p = 0.0008; I2 = 97 per cent); however; a high level of statistical heterogeneity was evident.

Most of the studies included in this systematic review observed a significant association between hearing loss and mild cognitive impairment.

Cholesteatoma is a benign but destructive epithelial lesion in the middle ear and/or mastoid. It is hard to translate data from previous research to daily clinical practice. In this study, factors influencing recurrence rates in daily clinical practice were identified.

The study included 67 patients who were treated for a cholesteatoma with combined approach tympanoplasty. The average follow-up time was 35 months.

The recurrence rate was 23.3 per cent in adults and 45.5 per cent in children. Predictors of recurrence were younger age and a low tegmen. A cholesteatoma in a child and the simultaneous presence of a low tegmen led to recurrence in 82.8 per cent of the patients.

Patients – especially children – with a low tegmen have an increased risk of recurrence. It is recommended that ENT surgeons be aware of recurrence in children, particularly in the case of a low tegmen.

To determine the short- and long-term outcomes of triple semicircular canal occlusion as a potential alternative for patients with intractable Ménière's disease.

A retrospective case series was performed in university settings, enrolling patients with intractable Ménière's disease with previous maximum treatment, who underwent transmastoid, triple semicircular canal occlusion. The study documented: pre- and post-operative Dizziness Handicap Inventory scores at six weeks and one year post-treatment, pure tone audiometry, and surgical aspects.

Two female patients, aged 42 and 65 years, underwent unilateral three-semicircular-canal occlusion. Their respective Dizziness Handicap Inventory scores improved from 88 to 68 and 54 to 30 at six weeks post-operatively, with scores of 66 and 0 at one year post-treatment. The one patient with pre-existing functional hearing maintained her hearing threshold post-operatively.

Triple semicircular canal occlusion is a safe, hearing-preserving, extracranial alternative technique that can control rotatory vertigo in patients with intractable Ménière's disease, when other measures have failed.

Studying otolith functions after unilateral vestibular neuritis using ocular vestibular-evoked myogenic potentials and subjective visual vertical tests could give different results.

A total of 39 patients underwent a vestibular assessment that included the Dizziness Handicap Inventory and horizontal and vertical semicircular canal function testing with video head impulse testing, ocular vestibular-evoked myogenic potential testing, cervical vestibular-evoked myogenic potentials and subjective visual vertical testing.

All patients showed a significant alteration (asymmetry ratio more than 40 per cent) for ocular vestibular-evoked myogenic potentials as well as for subjective visual vertical testing (more than −2° to more than +2°) during the acute phase, whereas after 72 hours from the acute vertigo attack normal values (asymmetry ratio less than 40 per cent) were found in 6 out of 39 patients for ocular vestibular-evoked myogenic potentials and 36 out of 39 for the subjective visual vertical (less than −2° to less than +2°).

Ocular vestibular-evoked myogenic potentials are the most suitable test to evaluate otolith functions in patients with unilateral vestibular neuritis in the acute and sub-acute phase.

Cleft palates are one of the most common congenital malformations. Because of the loss of Eustachian tube function, middle-ear ventilation is reduced. The aim of this study was to determine if middle-ear effusions were present at birth or at the three-month audiological evaluation.

A total of 53 children with a cleft palate were included. Data review included the results of newborn hearing screening, microscopic findings, a tympanometry, a free field audiometry and intra-operative findings.

A total of 58.4 per cent of patients had a median, 26.4 per cent had a bilateral, 11.3 per cent had a unilateral and 3.8 per cent had a limited soft palate cleft. Newborn hearing screening showed a pass in 83.1 per cent of newborns bilaterally. The first ear microscopy showed a bilateral middle-ear effusion in 90.6 per cent of cases. During cleft surgery, bilateral paracentesis was performed in all cases, and in 90.6 per cent middle-ear effusion was sucked out.

The majority of children with a cleft palate do not present with middle-ear effusion at birth. It develops within several days or weeks of life.

Three-dimensional endoscopes provide a stereoscopic view of the operating field, facilitating depth perception compared to two-dimensional systems, but are not yet widely accepted. Existing research addresses performance and preference, but there are no studies that quantify anatomical orientation in endoscopic ear surgery.

Participants (n = 70) were randomised in starting with either the two-dimensional or three-dimensional endoscope system to perform one of two tasks: anatomical orientation using a labelled three-dimensional printed silicone model of the middle ear, or simulated endoscopic skills. Scores and time to task completion were recorded, as well as self-reported difficulty, confidence and preference.

Novice surgeons scored significantly higher in a test of anatomical orientation using three-dimensional compared to two-dimensional endoscopy (p < 0.001), with no significant difference in the speed of simulated endoscopic skills task completion. For both tasks, there was lower self-reported difficulty and increased confidence when using the three-dimensional endoscope. Participants preferred three-dimensional over two-dimensional endoscopy for both tasks.

The findings demonstrate the superiority of three-dimensional endoscopy in anatomical orientation, specific to endoscopic ear surgery, with statistically indistinguishable performance in a skills task using a simulated trainer.

To assess benefits of surgical intervention at an early age and focus on surgical techniques using exclusively autologous cartilage grafts.

Five children aged 8–15 years, treated between March 2016 and 2020, underwent augmentation rhinoplasty using autologous cartilage, with post-operative follow up ranging from 1.5 to 2 years. Photographs and Rhinoplasty Outcome Evaluation questionnaire scores were examined.

Augmentation was achieved without complications. No restricted skin or mucosal pockets were encountered. Patients showed improved confidence and perspective with regard to self-image, and were less socially self-conscious. There was significant improvement in all Rhinoplasty Outcome Evaluation questionnaire scores.

Early surgery allows augmentation with easier release of skin and mucosal pockets, and without the tension otherwise encountered if primary augmentation is performed at a later age. It offers a chance to improve confidence and self-perception in a growing child conscious about their appearance, which may make them socially withdrawn. Autologous cartilage gives better results than bone grafts, and is comparable with silicone but without its complications.

To correlate computed tomography findings and endoscopic localisation of the anterior ethmoidal artery during surgery, and to analyse the intranasal landmarks and abnormalities of the artery.

The anterior ethmoidal artery was studied with high-resolution computed tomography and endoscopic surgery in 30 patients undergoing functional endoscopic sinus surgery (group A), and with endoscopic dissection on 30 human cadavers (group B).

The anterior ethmoidal artery was demonstrated on computed tomography in 25 patients and intra-operatively in 12 (group A). It was identified in 26 cadavers (group B). Dehiscence of bony canal and branching was noted in 10.53 per cent of cases. The mean (± standard deviation) intranasal length of the anterior ethmoidal artery was 7.29 (± 1.21) mm, the distance of the artery from the axilla of the middle turbinate was 16.24 (± 2.75) mm, and the mean distance from the ground lamella was 8.97 (± 1.46) mm.

High-resolution computed tomography scanning prior to functional endoscopic sinus surgery is mandatory to identify the anterior ethmoidal artery. Endoscopically, the axilla of the middle turbinate and the ground lamella can serve as dependable reference points to identify the artery. Cadaver dissection improves understanding of anatomy.

This study aimed to determine the number, reasons and costs of surgical voice restoration related tracheoesophageal valve attendances over 36 months at a head and neck oncology unit.

Demographic, medical and valve related details from all patient contacts were recorded, including self-change information, urgent appointment information, modifications required and costs of prostheses.

Over 3 years, 99 patients underwent 970 valve changes. The main reasons for changes were central leakage, prophylactic change and self-change at home. Changes were significantly more frequent in the first 12 months (mean, 42 days) compared with longstanding patients (mean, 109.96). Intervals between changes were unpredictable; no predictive factors reached statistical significance. Mean expenditure on valves was £966.63 per week (including value added tax and in-house customisation).

Valve lifespan is comparable with outcomes in similar units despite more pre-emptive and patient-led changes and more comprehensive data inclusion. Investigation into how patient satisfaction and costs relate to valve selection and units’ service delivery models is needed.

Risk factors for salivary gland carcinoma are poorly understood. Although links between background radiation, smoking and obesity have been previously suggested, no studies have so far established any significant results. This study aimed to establish correlations between common environmental and lifestyle risk factors and different subtypes of salivary gland carcinoma.

A study of population data in Wales spanning 27 years was conducted; 2 national databases were used to identify 356 cases of primary salivary gland carcinoma over this period. Histological subtype of cancer and geographical location of each case was recorded. Public health data was used to establish radon levels, smoking, obesity and activity levels of populations in each geographical location. A population matched multivariate analysis of variance analysis was performed using histological subtype and risk factor data for each geographical location.

A significantly higher incidence of mucoepidermoid cancer in populations with higher background radon levels (p = 0.006), epithelial-myoepithelial cancer in populations with higher smoking levels (p = 0.029) and adenoid cystic cancer in populations with higher obesity levels (p = 0.028) was found.

To the authors’ knowledge, this is the first study to establish significant links between background radiation, smoking and obesity with different subtypes of salivary gland carcinoma.

Rhino-orbital mucormycosis was seen in epidemic proportions during the second wave of the coronavirus disease 2019 pandemic. Many of these post-coronavirus rhino-orbital mucormycosis patients underwent maxillectomy for disease clearance. Rehabilitating such a large number of patients with surgical obturators as an emergency in a low-income setting was challenging.

High-density polyurethane foam was used to make a temporary obturator for patients who underwent maxillectomy. These obturators helped alleviate functional problems like dysphagia and nasal regurgitation, improving nutritional outcomes and shortening the hospital stay.

The coronavirus disease 2019 pandemic gave physicians time-sensitive challenges, for which immediate alternatives to established care were required. A maxillary obturator made of high-density polyurethane foam is an innovative solution to rehabilitate maxillectomy patients in the immediate post-operative period.

Cochlear implantation can be used when a patient's hearing cannot satisfactorily be improved after optimised hearing aid fitting. However, in patients with a cochlear nerve or brain disorder affecting hearing, the benefits of cochlear implants are not so straightforward.

This paper describes a 58-year-old patient suffering from multiple sclerosis and profound sensorineural hearing loss, rehabilitated with a cochlear implant. Literature concerning cochlear implantation in demyelinating conditions was systematically reviewed using PubMed/Medline and Web of Science databases.

The patient's cochlear implantation was successful, with speech discrimination scores remaining above 90 per cent for eight years post-operatively. No previous cases of cochlear implantation with multiple sclerosis related hearing loss have been reported, despite the high incidence of hearing loss in multiple sclerosis patients.

This paper demonstrates that multiple sclerosis lesions should not be an exclusion criterion in an otherwise suitable candidate for cochlear implantation.

Neonatal nasal obstruction may result in respiratory distress, feeding difficulties, sleep apnoea and failure to thrive; hence, it requires thorough evaluation and prompt intervention. Congenital inferior turbinate hypertrophy is relatively uncommon, and its presentation can mimic other congenital nasal anomalies.

This paper reports two cases of congenital inferior turbinate hypertrophy in neonates that resulted in significant respiratory distress, feeding difficulties and sleep disturbance. Both patients were successfully treated surgically by endoscopic nasal dilatation and stenting. A literature search was performed to identify articles on congenital inferior turbinate hypertrophy in neonates and its management.

Albeit rare, congenital inferior turbinate hypertrophy should be considered a differential diagnosis in newborns presenting with respiratory distress at birth.

A 43-year-old woman presented with a 3-week history of globus sensation and malaise. A computed tomography scan of her neck showed a large right paratracheal abscess secondary to an infected tracheal diverticulum. The patient was admitted under the ENT surgical team, and underwent incision and drainage of the abscess. There were no post-operative complications and she was discharged home after 2 days, on oral antibiotics.

This case demonstrates that a tracheal diverticulum may become infected and present as a cervical abscess. To our knowledge, this is the fourth reported case in the international literature of abscess formation related to an infected tracheal diverticulum.
