This paper reviews our experience of potassium titanyl phosphate (KTP) laser in transcanal totally endoscopic cholesteatoma surgery.

A prospective cohort study was conducted in a tertiary referral centre, involving a consecutive series of children with cholesteatoma who underwent totally endoscopic cholesteatoma surgery with a KTP laser.

The patients’ mean age was 10.5 years (range, 1.8–18 years). A KTP laser was used in 70 of the 83 cases (84 per cent). The laser was not used in 13 ‘clean’ cases, in which disease was removed more easily. Residual disease was detected in five cases (6 per cent), of which the KTP laser had been used in four (5 per cent). No complications were associated with KTP laser use.

The combination of KTP laser use with endoscopic visualisation is effective for minimising the risk of residual disease using a minimally invasive surgical approach. The thin, semi-flexible fibre carrier of the KTP laser is ideally suited to work alongside the endoscope within the narrow confines of the ear canal.

To determine whether patients would have equivalent or improved outcomes when receiving non-surgical management versus surgical removal for vocal process granulomas.

A chart review was performed for 53 adults with vocal process granulomas. All patients received baseline anti-reflux treatment consisting of twice-daily proton pump inhibitors and vocal hygiene education. Further treatment approaches were divided into non-surgical (i.e. inhaled corticosteroids, voice therapy, botulinum toxin injections) and surgical groups. Subjective parameters (Voice Handicap Index 10 and Reflux Symptom Index) and outcomes were tabulated and statistically compared. Cause of granuloma was also analysed to determine if this influenced outcomes.

Of 53 patients, 47 (89 per cent) experienced reduction in granuloma size, while 37 (70 per cent) experienced complete resolution. The rate of complete granuloma resolution after initial treatment strategy alone was significantly higher in non-surgical compared to surgical patients (67 and 30 per cent, respectively; p = 0.039). No difference in outcome was seen between iatrogenic and idiopathic granulomas.

Non-surgical patients were more likely to experience initial treatment success than those who underwent surgical removal. Continued emphasis should be placed on conservative treatment options prior to surgery for patients with this condition.

This study aimed to assess the outcomes of a prelacrimal recess approach assisted middle meatal antrostomy in the management of hard to reach maxillary sinus pathologies.

Twenty-five patients with maxillary sinus pathology underwent prelacrimal recess approach assisted middle meatal antrostomy (with a prelacrimal recess width of more than 3 mm). Patients were prospectively evaluated using both the Arabic version of the Sino-Nasal Outcome Test-22 and nasal endoscopy at least 6 months post-operatively.

Our study included 25 maxillary sinuses (13 with antrochoanal polyps, 10 with maxillary fungal ball and 2 with a migrated part of a tooth). At a mean follow-up period of 10.9 months, all patients showed significant improvement in total mean Sino-Nasal Outcome Test-22 score. There was recurrence of one case with antrochoanal polyp and two cases with asymptomatic synechia. Injury to the nasolacrimal duct was not reported.

A prelacrimal recess approach assisted middle meatal antrostomy is a reliable and safe technique to manage pathologies in hard to reach regions within the maxillary sinus.

This study investigated the risk of contamination of lidocaine hydrochloride 5 per cent w/v and phenylephrine hydrochloride 0.5 per cent w/v topical solution after modification of the application technique.

This paper reports a prospective basic sciences study involving 22 study samples and 1 control sample of the lidocaine hydrochloride and phenylephrine hydrochloride topical anaesthetic spray. The samples were assessed for microbiological contamination after a single use on patients using a modified application technique. The modification involves keeping the nozzle (actuator) pressed down whilst withdrawing the spray to at least 30 cm (1 ft) from the patient, before releasing the nozzle (actuator) and subsequently reapplying the spray.

Three of the 23 samples confirmed bacterial growth in the bottle contents, but there was no growth in any of the samples from the pump. These bacteria are considered to be contaminants.

There is a potential to use the lidocaine hydrochloride 5 per cent w/v and phenylephrine hydrochloride 0.5 per cent w/v topical solution as a multi-use spray by changing the actuator between patients. This would have significant beneficial cost implications without the attendant infection control risk.

To assess intubation management in difficult airway patients by performing a multidisciplinary pre-operative examination of the airway using a flexible fibre-optic laryngoscope.

Patients with a known but stable difficult airway were evaluated prior to surgery in the pre-operative holding suite by both an ENT surgeon and an anaesthesiologist via a fibre-optic laryngeal examination.

Performing a pre-operative fibre-optic examination of the difficult airway led to a change in intubation strategy in 6 out of 12 cases. Intubation ‘first-pass’ success occurred in 9 out of 12 (75 per cent) of our patients.

By performing a multidisciplinary airway examination immediately prior to surgery, a safe plan to intubate on the initial attempt was developed. This resulted in improved first-pass success at intubation compared to historical data.

To evaluate VIIth–XIIth cranial nerve (hypoglossal–facial nerve) anastomosis results by age.

A total of 34 patients who attended a follow-up visit in 2016, aged 20–63 years, were enrolled. The House–Brackmann facial nerve function grading system and the Facial Clinimetric Evaluation scale were applied.

Regarding post-anastomosis facial nerve function, in the group aged 40 years or less, 14 patients (78 per cent) had House–Brackmann grade III and 4 patients (22 per cent) had House–Brackmann grade IV facial nerve function post-anastomosis. In the group aged over 40 years, nine patients (56 per cent) had House–Brackmann grade III and seven patients (44 per cent) had House–Brackmann grade IV facial nerve function post-anastomosis. There was a statistically significant difference between the two groups in mean facial movement domain scores (p = 0.02). Analysis between age and facial movement score in all 34 patients demonstrated a moderate negative correlation (Pearson correlation coefficient: −0.38) and statistical significance (p = 0.02).

Facial reanimation yielded better results in younger than in older patients.

Pyriform aperture stenosis is a rare form of congenital nasal obstruction; it poses a management dilemma for otolaryngologists and physicians alike. It can result in poor weight gain and potentially life-threatening airflow obstruction. The challenge lies in the difficulty to predict which patients will require invasive operative management versus conservative therapy alone.

This case demonstrates the successful use of high-flow nasal cannula therapy in a young child with pyriform aperture stenosis.

Robust personal protective equipment is essential in preventing the transmission of coronavirus disease 2019 to head and neck surgeons who are routinely involved in aerosol generating procedures.

This paper describes the collective experience, across 3 institutes, of using a reusable half-face respirator in 72 head and neck surgery cases.

Cost analysis was performed to demonstrate the financial implications of using a reusable respirator compared to single-use filtering facepiece code 3 masks.

The reusable respirator is a cost-effective alternative to disposable filtering facepiece code 3 respirators. Supplying reusable respirators to individual staff members may increase the likelihood of them having appropriate personal protective equipment during their clinical duties.

Wide-ranging outcomes have been reported for surgical and non-surgical management of T3 laryngeal carcinomas. This study compared the outcomes of T3 tumours treated with laryngectomy or (chemo)radiotherapy in the northeast of England.

The outcomes of T3 laryngeal carcinoma treatment at three centres (2007–2016) were retrospectively analysed using descriptive statistics and survival curves.

Of 179 T3 laryngeal carcinomas, 68 were treated with laryngectomies, 57 with chemoradiotherapy and 32 with radiotherapy. There was no significant five-year survival difference between treatment with laryngectomy (34.1 per cent) and chemoradiotherapy (48.6 per cent) (p = 0.184). The five-year overall survival rate for radiotherapy (12.5 per cent) was significantly inferior compared to laryngectomy and chemoradiotherapy (p = 0.003 and p < 0.001, respectively). The recurrence rates were 22.1 per cent for laryngectomy, 17.5 per cent for chemoradiotherapy and 50 per cent for radiotherapy. There were significant differences in recurrence rates when laryngectomy (p = 0.005) and chemoradiotherapy (p = 0.001) were compared to radiotherapy.

Laryngectomy and chemoradiotherapy had significantly higher five-year overall survival and lower recurrence rates compared with radiotherapy alone. Laryngectomy should be considered in patients unsuitable for chemotherapy, as it may convey a significant survival advantage over radiotherapy alone.

Vocal fold injection augmentation is a recognised treatment modality for glottic insufficiency. Causes of glottal closure insufficiency include vocal fold paralysis, paresis, atrophy, sulcus vocalis, scarring and vocal fold deficiency after laryngeal surgery. A variety of materials exist for injection augmentation. This study aimed to compare voice improvement after injection augmentation between two injectable materials: carboxymethyl cellulose and calcium hydroxyapatite.

This retrospective study included 66 consecutive patients with glottic insufficiency who underwent injection augmentation.

Among the patients who received their first injection augmentation with carboxymethyl cellulose and their second injection augmentation with calcium hydroxyapatite (n = 28), voice quality improved significantly after both injection augmentations. No significant differences were observed in any of the objective and subjective voice quality measurements examined following carboxymethyl cellulose and calcium hydroxyapatite injections.

Voice improvement after injection augmentation depends mainly on the improvement of glottic closure, rather than the injection material.

This study aimed to compare the outcomes of ventilation tube insertion and balloon Eustachian tuboplasty as a first line treatment for otitis media with effusion in children.

This was a retrospective evaluation of 62 children, 30 cases that underwent balloon Eustachian tuboplasty (group 1) and 32 cases that underwent ventilation tube insertion (group 2), from July 2016 to April 2018.

The pre-operative air–bone gap of patients who underwent balloon Eustachian tuboplasty was 15–35 dB (mean: 27.6 ± 8.2 dB). The mean pre-operative air–bone gap decreased to 9.6 dB after a mean of 14.4 months (p < 0.05). The air–bone gap decreased from 25.6 dB to 17.6 dB in the ventilation tube group. There was a significant improvement in the air–bone gap values in both groups; however, this decrease was significantly higher in the balloon Eustachian tuboplasty group (p = 0.043).

Balloon Eustachian tuboplasty may be an effective and safe method for use as a first-line treatment of otitis media with effusion in children.

This paper aimed to: retrospectively analyse single-centre results in terms of surgical success, respiratory outcomes and adverse events after short-term follow up in obstructive sleep apnoea patients treated with upper airway stimulation; and evaluate the correlation between pre-operative drug-induced sleep endoscopy findings and surgical success.

A retrospective descriptive cohort study was conducted, including a consecutive series of obstructive sleep apnoea patients undergoing implantation of an upper airway stimulation system.

Forty-four patients were included. The total median Apnoea–Hypopnea Index and oxygen desaturation index significantly decreased from 37.6 to 8.3 events per hour (p < 0.001) and from 37.1 to 15.9 events per hour (p < 0.001), respectively. The surgical success rate was 88.6 per cent, and did not significantly differ between patients with or without complete collapse at the retropalatal level (p = 0.784). The most common therapy-related adverse event reported was (temporary) stimulation-related discomfort.

Upper airway stimulation is an effective and safe treatment in obstructive sleep apnoea patients with continuous positive airway pressure intolerance or failure. There was no significant difference in surgical outcome between patients with tongue base collapse with or without complete anteroposterior collapse at the level of the palate.

The coronavirus disease 2019 pandemic has necessitated rapid adaptations to all levels of clinical practice. Recently produced guidelines have suggested additional considerations for tracheostomy and advocated full personal protective equipment, including filtering facepiece code 3 masks. Air seal with filtering facepiece code 3 masks is often challenging, and full-face respirators and powered air-purifying respirators with hoods need to be employed. The infection prevention benefits of this equipment are accompanied by potential issues in communication.

In an attempt to minimise surgical error through miscommunication, the authors sought to introduce a simple sign language system that could be used as an adjunct during surgery.

Following evaluation of pre-existing sign language platforms and consideration of multiple surgical factors, 14 bespoke hand signals were ultimately proposed.

Whilst this novel sign language system aims to bridge the communicative gap created by additional personal protective equipment, further development and validation of the proposed tool might be beneficial.

To ascertain whether simulation-based teaching is superior to lecture-based teaching for an induction programme using a home-made induction model.

A simulation-based induction programme was designed and separate lecture-based teaching covering the same content was organised for junior doctors. The junior doctors were asked to complete pre- and post-induction surveys regarding confidence and anxiety levels. The skills taught included microsuction, flexible nasendoscopy, and anterior and posterior nasal packing. Structured interviews were conducted after the programme to gain qualitative data for analysis. The trainees’ knowledge retention was compared using a standardised written assessment one month after the session.

Simulation-based teaching using the induction model was associated with a statistically significant increase in confidence levels and reduction in anxiety levels, and was associated with greater knowledge retention.

A regular simulation induction programme should be introduced using the induction model, as it leads to better knowledge retention and increased confidence levels.

Post-surgical bleeding after tonsillectomy occurs in 2–7 per cent of cases. This study examined whether heart rate and haematocrit changes are associated with the amount of bleeding.

In this retrospective analytical study, data were collected from the medical charts of patients admitted with post-surgical bleeding.

Over the course of 10 years, there were 218 cases of post-operative bleeding in children aged under 18 years. There was a significant increase in heart rate after the bleeding had started, and a significant decrease in both haemoglobin and haematocrit levels (p < 0.05). There was no significant correlation between the differences in haemoglobin and haematocrit and changes in heart rate.

No correlation was found between the differences in haemoglobin and haematocrit levels and the changes in heart rate from before the surgery to after the bleeding had started. The monitoring of paediatric patients’ heart rate after tonsillectomy surgery solely for the purpose of predicting acute blood loss is therefore discouraged.

Transoral laser microsurgery for glottic squamous cell carcinoma is the standard of care at many institutions. Repeat transoral laser microsurgery for recurrence may avoid the need for radiotherapy and total laryngectomy. This study aimed to identify oncological and functional outcomes in a cohort of patients who had undergone repeat transoral laser microsurgery procedures.

A retrospective review of prospectively collected data of patients treated with transoral laser microsurgery for carcinoma in situ or tumour stages T1 or T2 glottic cancer, from 2003 to 2018.

Twenty patients were identified. Additional treatment was not needed in 45 per cent of patients. The five-year overall survival rate was 90 per cent. The disease-specific survival rate was 100 per cent. The laryngeal preservation rate was 85 per cent. There was improvement in mean Voice Handicap Index-10 scores following repeat transoral laser microsurgery treatment, when comparing the pre- and post-operative periods (mean scores = 15.5 vs 11.5, p = 0.373).

Repeat transoral laser microsurgery can be an oncologically safe alternative to other salvage therapies for glottic squamous cell carcinoma recurrence, without sacrificing functional outcomes.

To compare the results of endoscopic and microscopic ossicular chain reconstruction surgery.

Patients undergoing ossicular chain reconstruction surgery via an endoscopic (n = 31) or microscopic (n = 34) technique were analysed for age, gender, Middle Ear Risk Index, ossicular chain defect, incision type, ossicular chain reconstruction surgery material, mean air conduction threshold, air–bone gap, air–bone gap gain, word recognition score, mean operation duration and mean post-operative follow up.

Post-operative air conduction, air–bone gap and word recognition score improved significantly in both groups (within-subject p < 0.001 for air conduction and air–bone gap, and 0.026 for word recognition score); differences between groups were not significant (between-subject p = 0.192 for air conduction, 0.102 for air–bone gap, and 0.709 for word recognition score). Other parameters were similar between groups, except for incision type. However, endoscopic ossicular chain reconstruction surgery was associated with a significantly shorter operation duration (p < 0.001).

Endoscopic ossicular chain reconstruction surgery can achieve comparable surgical and audiological outcomes to those of microscopic ossicular chain reconstruction surgery in a shorter time.

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.

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.

The simulator provides an effective tool on which surgical trainees can practise, develop and maintain a variety of otomicroscopy skills.

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.

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.

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.

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.

Nasal obstruction when lying down is a common complaint in patients with chronic nasal obstruction, but rhinomanometry is typically performed in the sitting position. This study aimed to analyse whether adding rhinomanometry in a supine position is a useful examination.

A total of 41 patients with chronic nasal obstruction underwent rhinomanometry and acoustic rhinometry, sitting and supine, before and after decongestion, as well as an over-night polygraphy.

Total airway resistance was measurable in a supine position in 48 per cent (14 of 29) of the patients with total airway resistance of equal to or less than 0.3 Pa/cm3/second when sitting and in none (0 of 12) of the patients with total nasal airway resistance of more than 0.3 Pa/cm3/second when sitting. After decongestion, this increased to 83 per cent and 58 per cent, respectively.

Increased nasal resistance when sitting predicts nasal breathing problems when supine. Rhinomanometry in a supine position should be performed to diagnose upper airway collapse when supine.
