This retrospective study aimed to establish a robust rating system for assessing post-operative outcomes in congenital aural atresia patients undergoing auricular reconstruction. The newly introduced EAR scale, a weighted grading system, not only considers anatomical landmarks but also factors such as ear alignment. In addition, the outer-ear cartilage scale and the visual analogue scale (VAS) were introduced. These scales were compared among themselves and against two established scales.
Methods
Nine raters assessed 17 eligible patients who underwent auricular reconstruction between 2001 and 2020.
Results
The study compared inter-rater agreement among scales, with the EAR scale proving the most reliable (Krippendorff's alpha coefficient, α = 0.45), outperforming existing measures. The outer-ear cartilage scale and the VAS exhibited lower inter-rater agreement, indicating inferiority in assessing aesthetic outcomes.
Conclusion
The EAR scale emerged as an effective tool for evaluating post-operative outcomes in congenital aural atresia auricular reconstruction.
Cocaine is one of the most used recreational drugs. Whilst medical uses exist, chronic recreational nasal use of cocaine is associated with progressive destruction of the osseocartilaginous structures of the nose, sinuses and palate – termed cocaine-induced midline destructive lesions.
Case report
A 43-year-old male with a history of chronic cocaine use, presented with conductive hearing loss and unilateral middle-ear effusion. Examination under anaesthesia revealed a completely stenosed left Eustachian tube orifice with intra-nasal adhesions. The adhesions were divided and the hearing loss was treated conservatively with hearing aids. Whilst intra-nasal cocaine-induced midline destructive lesions are a well-described condition, this is the first known report of Eustachian tube stenosis associated with cocaine use.
Conclusion
This unique report highlights the importance of thorough history-taking, rhinological and otological examination, and audiometric testing when assessing patients with a history of chronic cocaine use. This paper demonstrates the complexity of managing hearing loss in such cases, with multiple conservative and surgical options available.
This chapter focuses in particular on import restrictions and export controls as weapons of economic warfare as used against Russia, as opposed to the sanctions measures that are the focus of much of the book. These tools supplement the sanctions measures and help promote the same foreign policy ends through alternative means. For example, the chapter examines changes to Russia’s “most favored nation” status, and the resulting effect on imports into the U.S. from Russia. Import bans were also implemented on many items from Russia in multiple jurisdictions. Export controls of high-tech items are also discussed.
Laterality of paired organs involves the function of the eyes, ears, hands and feet. Whilst most people have a right-handed preference, about 10 per cent are left-handed. Similarly, the right eye is usually preferred to the left. Medicine is both taught and practised for those with right hand and eye preference, and left-handed medical students and doctors must negotiate the right-handed world.
Objective
This brief review looks at society's attitudes, medical training and the practice of otolaryngology in the UK towards laterality and handedness.
Method
Literature review.
Results
Studies suggest that left-handers are more versatile and so are more ambidextrous. Conversely, this may result in problems when a right-hander tries to undertake a procedure with the non-dominant hand.
Conclusion
Cultures and attitudes are changing towards those who are left-handed. Left-handed surgeons may encounter difficulties in the clinical environment throughout their training.
Chondrodermatitis nodularis helicis is a benign, but painful inflammatory condition of the ear, characterised by a tender nodule located on the helix or antihelix. This study aimed to investigate the occurrence of chondrodermatitis nodularis helicis associated with the use of coronavirus disease 2019 masks during the pandemic.
Method
A retrospective single-centre study was performed from February 2020 to February 2022 in the Maxillo-Facial Unit at the University Hospital of Siena, Italy.
Results
During the indexed period, 11 patients were affected by chondrodermatitis nodularis helicis. All patients wore a mask for more than 8 hours a day, every day for several months.
Conclusion
Although there is no certain proof of the correlation between masks and chondrodermatitis nodularis helicis, an increase in the incidence of this condition was highlighted in our single-centre experience in the pandemic period. The prolonged use of coronavirus disease 2019 masks may explain this correlation.
Cholesteatomas present a high risk for residual and recurrent disease, and the surveillance of post-operative patients can be challenging. Diffusion-weighted magnetic resonance imaging is becoming the preferred method for investigating recidivism; however, false positive imaging findings increase the risk of patients undergoing unnecessary second look surgery.
Case reports
This study reports two patients with false positive diffusion restriction associated with cartilage grafts that mimicked cholesteatoma and resulted in second look surgery with no disease found at operation. This study also discusses the related medical literature, including potential causes of abnormal diffusion restriction and methods to negate this.
Conclusion
Caution should be exercised when considering second look surgery in the presence of a cartilage graft and a high confidence of disease clearance. A multi-disciplinary approach is recommended for the operating surgeon to review the images with a radiologist.
Although today there is extensive scientific literature on aural myiasis, a historical study of the subject has yet to appear. This short article reports the first description of aural myiasis in the Western medical literature.
Methods
Methods involved: (1) scholarship review of ear diseases within Ancient Greek and Roman medical texts (L'Année philologique); (2) linguistic analysis for text identification through the Library of Latin Texts, the Thesaurus Linguae Latinae and the Loeb Classical Library; and (3) translation of the Latin texts that described cases of aural myiasis with commentary.
Results
To our knowledge, the earliest case of aural myiasis in Latin medical literature is reported by the Roman encyclopaedist Celsus (first century CE). In his De Medicina, he describes cases of Wohlfahrtia magnifica maggot infestation of the ear and how to treat affected patients.
Conclusion
Despite present advances in otology, we believe that much insight can still be gained from this ancient example of medical history in ear diseases. A more comparative analysis of the subject is to be considered in the future, which will provide more data from different cultures and times.
Round window approaches are used to insert a cochlear implant electrode array into the scala tympani. This study aimed to review the literature to find the reported round window approaches.
Method
This review was performed according to the Preferred Reporting Items for Systematic Review and Meta-Analyses (‘PRISMA’) guidelines. Articles that described their surgical approach to the round window were included. The PubMed, Scopus, Web of Science and Cochrane Library electronic databases were searched through to June 2021. The study protocol was registered on Prospero (reference number: CRD42021226940).
Results
A total of 42 reports were included. The following approaches were documented: the standard facial recess, keyhole, retrofacial, modified suprameatal, transaditus, combined posterior tympanotomy and endomeatal, modified Veria, canal wall down approaches, and endoscopically assisted technique.
Conclusion
This review suggested that there are numerous distinct round window approaches, providing alternatives when the round window is inaccessible through the standard facial recess.
This study aimed to analyse the effectiveness of using the bony sigmoid sinus plate for repair of meato-mastoid fistulae.
Method
A retrospective study of all cases between January 2013 and December 2019 at our secondary-tertiary centre was conducted. Inclusion criteria for study were: (1) cases with focal meato-mastoid fistulae and (2) focal meato-mastoid fistulae that were repaired by using bony sigmoid sinus plate using the bony sigmoid sinus plate technique. There were 13 cases that fulfilled these criteria.
Results
The outcome of the repair of meato-mastoid fistulae with bony sigmoid sinus plate was very encouraging. All 13 cases did well. Two patients had delayed epithelialisation at 9 and 12 months after surgery.
Conclusion
The technique of repairing meato-mastoid fistulae by using bony sigmoid sinus plate is simple, repeatable and provides effective physiological reconstruction of the posterior canal wall. Bony sigmoid sinus plate is easily and locally available in all cases undergoing cortical mastoidectomy. This plate of bone has a curvature, consistency and structure that match well with that of the posterior or superior canal wall. In addition, this technique is cost-effective with good patient compliance.
Lateral temporal bone resections are used in the management of locally advanced peri-auricular cutaneous squamous cell carcinomas, but there is still conflicting evidence regarding the staging, surgical and adjuvant treatment decisions.
Methods
A retrospective analysis was performed on all patients who underwent lateral temporal bone resection for cutaneous squamous cell carcinoma between January 2015 and December 2019 at a dedicated tertiary oncology referral centre.
Results
Twenty-nine patients were included, with a median age of 77 years. Computed tomography, magnetic resonance imaging and positron emission tomography showed good diagnostic accuracy in identifying disease in the parotid gland, external auditory canal and mastoid bone, but had poor sensitivity in identifying cervical nodal metastasis. Six patients had recurrence at a median of 4.8 months post-operatively. Tumour differentiation (p = 0.0040) and post-operative radiotherapy (p = 0.0199) were associated with significantly better recurrence-free survival.
Conclusion
Lateral temporal bone resection for peri-auricular cutaneous squamous cell carcinoma requires careful surgical planning using clinico-radiological correlation, particularly in patients with poorly differentiated tumours.
Mastoid exploration remains an advanced, mainstay operation within ENT, in which the surgical trainees’ role has been debated. This audit compares mastoid exploration outcomes between trainees and consultants.
Methods
Cortical mastoidectomy, atticotomy, atticoantrostomy, modified radical mastoidectomy, combined-approach tympanoplasty and revision mastoidectomy operations performed between 2009 and 2020 were reviewed. Complications assessed were: facial palsy, labyrinth injury, dead ear, disease recurrence and time to recurrence. The chi-square test was used to determine significant associations.
Results
A total of 118 operations were surveyed. Thirty-five per cent of procedures (n = 41) were performed by trainees under supervision, and 65 per cent (n = 77) were carried out solely by consultants. Patients from 5 per cent of trainees’ operations (n = 2) developed recurrence, compared with 7.8 per cent of consultants’ (n = 6) (p = 0.55). No other complications developed in either group.
Conclusion
The results corroborate those of other studies, indicating no significant increase in complication rate from consultants to trainees. Trainees likely completed less complicated cases. The stepwise incorporation of trainees did not compromise patient safety.
This case series, conducted during the coronavirus disease 2019 pandemic, investigates the impact of leaving aural foreign bodies in situ for a prolonged period of time, including the risk of complications and success rates of subsequent removal attempts.
Method
A retrospective study of aural foreign body referrals over a six-month period was carried out.
Results
Thirty-four patients with 35 foreign bodies were identified (6 organic and 29 inorganic). The duration of foreign bodies left in situ ranged from 1 to 78 days. Four patients suffered from traumatic removal upon initial attempts. First attempts made by non-ENT specialists (68.8 per cent) all failed and were associated with a high risk of trauma (36.4 per cent).
Conclusion
Because of the coronavirus disease 2019 pandemic, this is the first case series to specifically investigate the relationship between the duration of aural foreign bodies left in situ and the risk of complications. Our data suggest that prolonged duration does not increase the incidence of complications.
To evaluate the spectral resolution achieved with a cochlear implant in users who were implanted using round window route electrode insertion versus a traditional cochleostomy technique.
Methods
Twenty-six patients were classified into two groups according to the surgical approach: one group (n = 13) underwent cochlear implantation via the round window technique and the other group (n = 13) underwent surgery via cochleostomy.
Results
A statistically significant difference was found in spectral ripple discrimination scores between the round window and cochleostomy groups. The round window group performed almost two times better than the cochleostomy group. Differences between Turkish matrix sentence test scores were not statistically significant.
Conclusion
The spectral ripple discrimination scores of patients who had undergone round window cochlear implant electrode insertion were superior to those of patients whose cochlear implants were inserted using a classical cochleostomy technique.
This study aimed to provide a systematic review on survival outcome based on Pittsburgh T-staging for patients with primary external auditory canal squamous cell carcinoma.
Method
This study was a systematic review in compliance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines performed until January 2018; pertinent studies were screened. Quality of evidence was assessed using the grading of recommendation, assessment, development and evaluation working group system.
Results
Eight articles were chosen that reported on 437 patients with external auditory carcinoma. The 5-year overall survival rate was 53.0 per cent. The pooled proportion of survivors at 5 years for T1 tumours was 88.4 per cent and for T2 tumours was 88.6 per cent. For the combined population of T1 and T2 cancer patients, it was 84.5 per cent. For T3 and T4 tumours, it was 53.3 per cent and 26.8 per cent, respectively, whereas for T3 and T4 tumours combined, it was 40.4 per cent. Individual analysis of 61 patients with presence of cervical nodes showed a poor survival rate.
Conclusion
From this review, there was not any significant difference found in the survival outcome between T1 and T2 tumours. A practical classification incorporating nodal status that accurately stratifies patients was proposed.
To develop a simulator of the external auditory canal and tympanic membrane that enables surgical trainees to practise their otomicroscopy skills, which is particularly valuable at a time where there is limited patient contact because of the coronavirus disease 2019 lockdown.
Methods
A simulator of the external auditory canal and tympanic membrane was made using a cardboard bowl, a 2 ml syringe and a latex glove. The simulator was used to practise otomicroscopy skills, including microsuction, foreign body removal, myringotomy and grommet insertion. Five doctors in the ENT department participated, ranging from core surgical training year two doctor to specialty doctor.
Results
The simulator provides an effective tool on which surgical trainees can practise, develop and maintain a variety of otomicroscopy skills.
Conclusion
This inexpensive, easy and quick-to-make simulator enables trainees to practise their otomicroscopy skills on an approximately accurate model during a time when there is minimal clinical opportunity to develop these skills, particularly because of the coronavirus disease 2019 pandemic.
To explore the feasibility of constructing a proof-of-concept artificial intelligence algorithm to detect tympanic membrane perforations, for future application in under-resourced rural settings.
Methods
A retrospective review was conducted of otoscopic images analysed using transfer learning with Google's Inception-V3 convolutional neural network architecture. The ‘gold standard’ ‘ground truth’ was defined by otolaryngologists. Perforation size was categorised as less than one-third (small), one-third to two-thirds (medium), or more than two-thirds (large) of the total tympanic membrane diameter.
Results
A total of 233 tympanic membrane images were used (183 for training, 50 for testing). The algorithm correctly identified intact and perforated tympanic membranes (overall accuracy = 76.0 per cent, 95 per cent confidence interval = 62.1–86.0 per cent); the area under the curve was 0.867 (95 per cent confidence interval = 0.771–0.963).
Conclusion
A proof-of-concept image-classification artificial intelligence algorithm can be used to detect tympanic membrane perforations and, with further development, may prove to be a valuable tool for ear disease screening. Future endeavours are warranted to develop a point-of-care tool for healthcare workers in areas distant from otolaryngology.
Individuals with superior semi-circular canal syndrome often describe vestibular symptoms elicited by loud sounds, as well as other pressure-induced symptoms. They also often report other symptoms, including autophony, hyperacusis, cognitive dysfunction, spatial disorientation, anxiety and migraine headaches. Symptoms occur due to the presence of a ‘third window’ created by the dehiscence of the superior semi-circular canal. This case report describes a minimally invasive technique to provide soft reinforcement of the round window.
Case report
Our patient underwent a permeatal procedure whereby the tympanic membrane was raised to allow inspection of the middle ear. The round window niche was identified and the round window membrane was reinforced with fat. The mucosa of the bony meatus leading to the round window was then disrupted before the application of a double layer of perichondrium to allow further reinforcement.
Conclusion
The case provides support for the use of ‘soft reinforcement’ as a simple and effective technique to treat the symptoms of superior canal dehiscence syndrome.
Comparing the feasibility of ovine and synthetic temporal bones for simulating endoscopic ear surgery against the ‘gold standard’ of human cadaveric tissue.
Methods
A total of 10 candidates (5 trainees and 5 experts) performed endoscopic tympanoplasty on 3 models: Pettigrew temporal bones, ovine temporal bones and cadaveric temporal bones. Candidates completed a questionnaire assessing the face validity, global content validity and task-specific content validity of each model.
Results
Regarding ovine temporal bone validity, the median values were 4 (interquartile range = 4–4) for face validity, 4 (interquartile range = 4–4) for global content validity and 4 (interquartile range = 4–4) for task-specific content validity. For the Pettigrew temporal bone, the median values were 3.5 (interquartile range = 2.25–4) for face validity, 3 (interquartile range = 2.75–3) for global content validity and 3 (interquartile range = 2.5–3) for task-specific content validity. The ovine temporal bone was considered significantly superior to the Pettigrew temporal bone for the majority of validity categories assessed.
Conclusion
Tympanoplasty is feasible in both the ovine temporal bone and the Pettigrew temporal bone. However, the ovine model was a significantly more realistic simulation tool.
The National Institute for Health and Care Excellence referral guidelines prompting urgent two-week referrals were updated in 2015. Additional symptoms with a lower threshold of 3 per cent positive predictive values were integrated. This study aimed to examine whether current pan-London urgent referral guidelines for suspected head and neck cancer lead to efficient and accurate referrals by assessing frequency of presenting symptoms and risk factors, and examining their correlation with positive cancer diagnoses.
Methods
The risk factors and symptoms of 984 consecutive patients (over a six-month period in 2016) were collected retrospectively from urgent referral letters to University College London Hospital for suspected head and neck cancer.
Results
Only 37 referrals (3.76 per cent) resulted in a head and neck cancer diagnosis. Four of the 23 recommended symptoms demonstrated statistically significant results. Nine of the 23 symptoms had a positive predictive value of over 3 per cent.
Conclusion
The findings indicate that the current referral guidelines are not effective at detecting patients with cancer. Detection rates have decreased from 10–15 per cent to 3.76 per cent. A review of the current head and neck cancer referral guidelines is recommended, along with further data collection for comparison.
To compare round window niche visibility as seen endoscopically during cochlear implant surgery with pre-operative high-resolution computed tomography of the temporal bone.
Methods
Nineteen patients scheduled for cochlear implantation, aged 2–20 years, were referred for computed tomography from October 2016 to March 2018. Angles were measured between the lines passing through the mid-sagittal plane and cochlear basal turn on the scans. Endoscopic round window niche visibility during posterior tympanotomy was categorised as: type I = 100 per cent, type IIa = more than 50 per cent, type IIb = less than 50 per cent or type III = 0 per cent. Pre-operative computed tomography measurements were used to predict round window niche visibility before surgery and correlated with intra-operative findings.
Results
The mean (range) of pre-operative angles on computed tomography for endoscopic visibility types I, IIa and IIb, were 64.06° (61.16–69.37°), 63.81° (58.61–71.35°) and 56.48° (50.37–59.05°), respectively, a statistically significant finding (one-way analysis of variance test, p = 0.016).
Conclusion
Pre-operative high-resolution temporal bone computed tomography measurements are useful in predicting round window niche visualisation as viewed endoscopically during posterior tympanotomy. The angle was more acute in type IIb compared to type I.
