The objective of this systematic review and meta-analysis was to evaluate the role of doxycycline in the management of chronic rhinosinusitis.

This was a systematic review using Ovid Medline, Cinahl, Scopus and Cochrane and was limited to meta-analyses, systematic reviews and randomised, clinical trials. A combination of the following search terms was used: ‘sinusitis’, ‘nasal polyps’, ‘doxycycline’ and ‘tetracycline’. Raw means and standard deviations were extracted from the included studies. The meta-analysis was performed using mean differences of pre- versus post-doxycycline treatment.

A total of 279 studies were screened, of which 5 studies met the criteria (all randomised, controlled trials published between 2010 and 2021). The interventions, endpoints and measured outcomes varied across all studies. Meta-analysis performed on pre- versus post-doxycycline treatment for Sino-Nasal Outcome Test-22, nasal polyp scores and symptom scores did not yield statistically significant results.

This review identified a small number of high-quality studies on the use of doxycycline in chronic rhinosinusitis. There does not seem to be convincing evidence for the routine use of doxycycline in patients with chronic rhinosinusitis. Further research may try to identify certain phenotypes of chronic rhinosinusitis that may better respond to doxycycline.

High rates of recidivism are reported after paediatric cholesteatoma surgery. Our practice has adapted to include non-echoplanar diffusion-weighted magnetic resonance imaging for the diagnosis of residual or recurrent cholesteatoma. This audit aimed to evaluate the performance of non-echoplanar diffusion-weighted magnetic resonance imaging in our paediatric population.

A retrospective review was conducted of non-echoplanar diffusion-weighted magnetic resonance imaging scans performed to detect residual disease or recurrence after surgery for cholesteatoma in children from 1 January 2012 to 30 November 2017 in our centre. Follow-up diffusion-weighted magnetic resonance imaging scans were reviewed to 16 August 2019.

Thirty-four diffusion-weighted magnetic resonance imaging scans were included. The sensitivity and specificity values of diffusion-weighted magnetic resonance imaging for detecting post-operative cholesteatoma were 81 per cent and 72 per cent, respectively. Positive predictive and negative predictive values were 72 per cent and 81 per cent, respectively.

Use of diffusion-weighted magnetic resonance imaging is recommended as a replacement for routine second-look surgical procedures in the paediatric population. However, we would caution that patients require close follow up after negative diffusion-weighted magnetic resonance imaging findings.

There is no consensus in the literature regarding the relationship between high-resolution computed tomography findings and hearing thresholds in pure-tone audiometry in otosclerosis. This study evaluated the association between high-resolution computed tomography findings and pure-tone audiometry in otosclerosis in the spongiotic phase.

A cross-sectional study was conducted of 57 ears with surgically confirmed stapes fixation and tomographic findings. Air conduction and bone conduction thresholds on audiometry, and air–bone gap, were analysed.

There were no correlations between sites affected by otospongiosis and air conduction threshold, bone conduction threshold or air–bone gap in the analysed tomographic images, but the diameter of the otospongiotic focus was greater in the presence of extension of the otospongiotic foci to the cochlear endosteum.

There were no relevant associations between high-resolution computed tomography findings and pure-tone audiometric measurements. However, the diameter of the otospongiotic focus was greater in the presence of extension of the otospongiotic foci to the cochlear endosteum.

Endoscopic hydro-mastoidectomy, in which mastoidectomy is performed underwater, can be employed during transcanal endoscopic ear surgery for cholesteatoma removal. It was hypothesised that endoscopic hydro-mastoidectomy might take less time than endoscopic non-underwater mastoidectomy because the endoscope does not need to be removed for cleaning.

This study compared the mastoidectomy and total operative durations between the endoscopic hydro-mastoidectomy (n = 25) and endoscopic non-underwater drilling (control, n = 8) groups. Moreover, it compared the size of resected areas of the external auditory canal between the two groups.

The mastoidectomy time of the endoscopic hydro-mastoidectomy group was significantly shorter than that of the control group (p < 0.01). The total operative time did not differ significantly between the endoscopic hydro-mastoidectomy and control groups (p = 0.17). The resected area was significantly larger in the endoscopic hydro-mastoidectomy group than in the control group (p < 0.05).

Endoscopic hydro-mastoidectomy enables more extensive bone resection within a shorter period.

This study aimed to understand, in a long-term follow-up study, whether the placement of grommets had been necessary after cleft palate surgical correction.

A case–control, retrospective study was carried out on consecutive paediatric patients who underwent surgical repair of a cleft palate.

The study population included 138 patients, divided into 2 groups: group 1 – patients in whom grommets were placed at the time of cleft palate surgery, and group 2 – patients in whom grommets were not placed at the time of cleft palate surgery. During the follow up, in groups 1 and 2, 65.2 per cent and 67.8 per cent, respectively, did not need subsequent grommet placement after cleft palate surgery.

Of patients, 56.5 per cent did not need ventilation tubes at any point during follow up. The placement of grommets is not innocuous; therefore, its use at the time of cleft palate surgical repair should be reconsidered.

This study aimed to analyse whether referral for specialist balance testing influences diagnosis and management of patients with dizziness.

This was a retrospective study examining patients referred for vestibular function testing between 1 January 2018 and 30 June 2018.

A total of 101 patients were referred, with 69 patients (68.3 per cent) receiving a preliminary ‘pre-vestibular function testing balance diagnosis’, which included benign paroxysmal positional vertigo (32.7 per cent), Ménière's disease (13.8 per cent) and migraine (14.9 per cent). Following vestibular function testing, revised diagnoses were achieved for 54 patients (53.5 per cent), including benign paroxysmal positional vertigo (14.9 per cent), Ménière's disease (3.0 per cent) and migraine (10.9 per cent). Pre-vestibular function testing balance diagnoses were confirmed for 32.4 per cent of patients. If no pre-vestibular function testing suspected diagnosis was provided, vestibular function testing was significantly more likely to be inconclusive. Following vestibular function testing, 38.6 per cent were discharged, 21.7 per cent were referred to another specialty and treatment was commenced for 17.8 per cent of patients.

Referral for vestibular function testing has a role when attempting to answer a clear clinical question. Diagnosing the underlying aetiology of complex imbalance is challenging, but diagnosis can be assisted by judicious use of vestibular function testing.

A seasonal trend of patients with idiopathic sudden sensorineural hearing loss may direct research into possible aetiology.

This study reviewed data from the medical records of patients who presented from 2004 to 2019 and who were diagnosed with new-onset idiopathic sudden sensorineural hearing loss. Seasonal pattern was assessed using chi-square and Rayleigh tests, and further confirmed by Monte Carlo simulation.

The study included 740 patients with a mean age of 48.3 years and a median age of 49 years. There was no statistical evidence for a difference in the distribution of sensorineural hearing loss cases for the four seasons of each year or with the cumulative data. New-onset idiopathic sudden sensorineural hearing loss cases averaged around 11 per month; there was no statistical evidence for a seasonal difference, as determined either by the Rayleigh test or with Monte Carlo simulation.

There was no evidence to support the claim that idiopathic sudden sensorineural hearing loss incidence displays a seasonal pattern. More research is necessary to explore potential external factors such as climate or infection.

This study aimed to analyse the computed tomography parameters for effective ventilation in patients with adhesive otitis media.

Twenty-six patients with unilateral adhesive otitis media were included in the study. The patients’ temporal bone computed tomography images were retrospectively reviewed. Eustachian tube length and diameter were measured. Mastoid pneumatisation and middle-ear size were evaluated by measuring petroclival and Eustachian tube–tympanic cavity ventilation angles.

The average Eustachian tube length was 38.4 mm and 38.9 mm in adhesive otitis media and healthy ears, respectively. The Eustachian tube diameter of the adhesive otitis media ears (1.47 mm) was significantly narrower than that of the healthy ears (1.83 mm). There were no significant differences in the angles between adhesive otitis media and healthy ears.

A narrow Eustachian tube diameter was associated with developing adhesive otitis media. Measuring Eustachian tube diameter is simple and can be routinely performed when examining temporal bone computed tomography images for Eustachian tube function evaluation.

This study aimed to determine the predictors of olfactory improvement after endoscopic sinus surgery among patients with chronic rhinosinusitis with nasal polyps.

This prospective cohort study included patients admitted to a university hospital between 2006 and 2012. Assessment using odour identification testing, a sinonasal symptom questionnaire, the Rhinosinusitis Disability Index and mucus biomarker levels was performed at various time points. Correlation of variables with identification score differences at six post-operative time points and at baseline was performed, followed by multiple linear regression to determine significant predictors at each of the six post-operative time points.

Baseline absence of acute sinusitis, elevated serpin F2 and anterior rhinorrhoea predict early olfactory improvement, whereas baseline allergic rhinitis predicts late olfactory improvement. Baseline odour identification score was the strongest predictor across all time points.

Patients with chronic rhinosinusitis and nasal polyps with worse disease or baseline olfactory function may benefit more from endoscopic sinus surgery in terms of olfactory improvement.

Effective nasal reconstruction requires skin and soft tissue cover, cartilage or bone structure, and mucosal lining. Ideal lining is thin, pliable and vascularised, making reconstruction challenging. This paper presents the first case series with long-term outcomes of pericranial flaps used as inner lining for nasal reconstruction.

Patients undergoing paramedial forehead flaps from 2007 to 2019 were identified using second-stage nasal reconstruction billing codes. Patients with pericranial flaps for lining, for whom there were data on resulting outcomes and complications, were identified.

Sixty-six patients underwent second-stage nasal reconstruction. Eighteen patients had paramedian forehead and pericranial flaps for inner lining reconstruction. The flap lining had no immediate post-operative complications. Three patients suffered partial to major reconstructive failure post radiotherapy. Other complications included nasal stenosis and orocutaneous fistula.

Combined with paramedian forehead flaps, the pericranial flap is reliable as inner lining for nasal reconstruction. It is easily accessible and useful in resections with limited mucosal options.

The coronavirus disease 2019 pandemic led to increased pressure on health services, which, combined with variable social restrictions, led to decreased referrals for head and neck cancer. This study assessed whether there were lasting changes to head and neck cancer referrals during different stages of the pandemic response in 2020 and 2021.

A retrospective review was conducted of all cases referred for suspected head and neck cancer to our institution in January 2020, April 2020, April 2021 and June 2021.

There was a rebound 91 per cent increase in referrals between April 2020 and April 2021 following the 59 per cent decrease in referrals between January 2020 and April 2020. Males made up 47.1 per cent of referrals in January 2020, 40 per cent in April 2020 and 37.82 per cent in April 2021.

Further research is recommended to investigate the reasons why there is a continued decline in male referrals and the effect this has on their outcomes.

This study aimed to compare the cost per use of video-rhinolaryngoscopy using reusable and disposable devices in a tertiary referral centre.

A cost-comparison study was performed that utilised retrospective cost data and prospective utilisation data to compare the total costs of using reusable video-rhinolaryngoscopes versus a single-use alternative.

It was estimated that 4776 and 1821 procedures were performed annually with reusable and disposable video-rhinolaryngoscopes, respectively. The cost per use was £66.61 for reusable devices versus £150.00 for disposable devices. The break-even point (i.e. when cost per use was equal, occurred at 1374 procedures per year). Thereafter, it was cheaper to use reusable devices.

Disposable rhinolaryngoscopes may present a cheaper solution to services with low rates of rhinolaryngoscope utilisation. However, for larger services considering replacement of their reusable rhinolaryngoscopes with disposable units, it is likely that the recurring costs will be prohibitive in the medium to long term.

To explore the diagnostic value of anteroposterior-to-transverse ratio for predicting thyroid cancer.

A total of 2306 nodules were divided into 5 groups according to their size. The ability of the anteroposterior-to-transverse ratio to predict thyroid cancer was analysed in each group on the basis of the sensitivity, specificity, accuracy and Youden index.

The median anteroposterior-to-transverse ratio was 0.83, with an interquartile range of 0.28. The area under the receiver operating characteristic curve was 0.709 (p < 0.001). When the diameter of a thyroid nodule was less than 1.5 cm, an anteroposterior-to-transverse ratio of more than 0.9 was associated with higher sensitivity, accuracy and Youden index, compared with an anteroposterior-to-transverse ratio of greater than 1.0, but the specificity was lower. When the diameter of a thyroid nodule was 1.5 cm or more, an anteroposterior-to-transverse ratio of greater than 0.9 was associated with higher sensitivity and Youden index, compared with an anteroposterior-to-transverse ratio of greater than 1.0, but specificity and accuracy were lower.

The anteroposterior-to-transverse ratio was a meaningful indicator of thyroid cancer, and its predictive effectiveness could be influenced by nodule size.

The added value of hybrid positron emission tomography is increasingly recognised in head and neck cancer. However, its potential role in salivary gland carcinomas has been scarcely investigated.

A consecutive cohort of 45 salivary gland carcinoma patients who underwent pre-therapeutic hybrid positron emission tomography and surgical resection was reviewed. This study investigated whether maximum standardised uptake value correlated with tumour phenotype.

Tumours of high-grade disease on histology (salivary duct carcinoma, carcinoma ex pleomorphic adenoma) had higher maximum standardised uptake value (Kruskal–Wallis test, p = 0.011) than low-grade tumours (adenoid cystic carcinoma and acinic cell carcinoma). Patients with pathologically confirmed node-positive disease had significantly higher maximum standardised uptake value of the primary tumour than patients with pathologically confirmed node-negative disease (Kruskal–Wallis test, p = 0.012).

Maximum standardised uptake value of the primary tumour may guide clinical decision-making in patients with salivary gland carcinomas, as a high maximum standardised uptake value is associated with high-grade tumour histology and the presence of lymph node metastases. Clinicians may consider more aggressive surgery for these patients.

To study the safety and efficacy of Artiss fibrin sealant in lateral neck dissection, focusing on drain retention time, length of hospital stay and post-operative complications.

A retrospective review was conducted of patients who underwent neck dissection in a UK hospital over a 12-month period.

Twenty-three patients were identified; 13 patients had Artiss and a drain, 10 patients had Artiss only. All drains were removed by post-operative day 2. No post-operative fluid collections or complications were recorded. Patients who had Artiss only without a drain were discharged on post-operative day 1.

The use of Artiss reduced the drain retention time and hospital stay, with no post-operative complications. Neck dissection can be safely undertaken with no drain, and can potentially be carried out as a day-case procedure, with the application of Artiss. These findings benefit patients and the National Health Service by improving the patient journey and reducing overall costs.

ENT is underrepresented in the curriculum, and this has been compounded by coronavirus disease 2019. Recent restructures have removed ENT placements from the curriculum. This lack of exposure needs to be addressed, and increased use of online learning represents an opportunity to facilitate this. This study aimed to evaluate whether online learning can effectively deliver undergraduate ENT teaching.

An online ENT module was created; content was structured on the Sheffield Medical School curriculum. Pre- and post-module tests and 5-point Likert scales were used to assess student knowledge and confidence, respectively.

A total of 115 participants were recruited. Test scores improved by 29 per cent (p < 0.001) and confidence by 66 per cent. Anatomy and ENT conditions demonstrated significant improvement in confidence, with a lower confidence score for examination.

This study showed improved knowledge and confidence, whilst highlighting greater efficacy in content over practical skills teaching. Online learning is a validated educational tool; however, it should not be used as a replacement but as an adjunct to supplement learning.

The operating theatre, as the primary learning environment for surgeons, needs to be conducive to achieve successful training. A validated 27-item questionnaire aimed at evaluating the training experience of higher surgical trainees in the operating theatre was developed.

The initial questionnaire was developed using a literature review and a focus group. Items were validated with content validity index (CVI) and Cronbach's alpha.

The initial version of 33 questions was modified in the focus group into a 29-item 4-point Likert scale questionnaire covering 3 areas. Of these 29 items, 27 reached the threshold CVI of 0.87, and they achieved a Cronbach's alpha of 0.89 from 17 responses.

The quantitative validations in the instrument are comparable to other existing medical education evaluation tools. Aspects of non-technical skills and human factors were featured heavily and perceived to be important for learning in the operating theatre.

Numerous factors are considered to impact on the rate of complications during salvage total laryngectomy procedures. Neck dissection could be one of these factors. This study analysed the pattern of lymph node metastasis and rate of occult neck disease during salvage total laryngectomy as well as the impact of neck dissection on survival and complication rates.

This was a retrospective analysis of a prospectively maintained laryngectomy database in two large tertiary teaching hospitals.

The rate of occult neck disease was 11.1 per cent. Most cases with occult neck disease had rT4 disease. Patients with complications, advanced tumour stage and positive margins had a significant decrease in overall survival. Patients receiving elective neck dissection did not have any survival benefit. Positron emission tomography-computed tomography showed a very high specificity and negative predictive value.

According to the low risk of occult neck disease when using contemporary imaging techniques as well as the lack of impact on survival, conservative management of the neck should be considered for crT1-T3 recurrence.

Early exposure and mentorship in surgical specialties like otolaryngology – head and neck surgery are critical for medical students. This paper presents initiatives implemented at our institution to engage early-career medical students with the field.

A hands-on laryngoscope workshop was organised, and a centralised online platform was created for research and mentorship opportunities using a collaborative project management tool. Both measures were advertised via e-mail to student interest groups and campus diversity groups. At the end of the workshop, participating students completed an online distributed survey.

Students’ perception of their knowledge of airway anatomy and related clinical scenarios significantly improved after the laryngoscopy workshop (p = 0.001 and p = 0.002, respectively). All attendees indicated that the workshop increased their comfort level with procedures and that they would recommend the workshop to colleagues. Nearly half of participants reported becoming ‘very interested’ in exploring otolaryngology – head and neck surgery through future elective courses.

Implementation of such initiatives at other institutions can generate medical student interest and may improve diversity in otolaryngology – head and neck surgery.
