Severe paediatric obstructive sleep apnoea in typically developing children with adenotonsillar hypertrophy is primarily managed surgically. Non-emergency ENT surgery was paused early in the coronavirus disease 2019 pandemic and children were offered medical management for obstructive sleep apnoea.

A service evaluation was performed to assess the impact of continuous positive airway pressure alongside medical management for severe obstructive sleep apnoea.

Over 5 months during 2020, in a tertiary care setting, two children (one boy and one girl), aged 2.7 years and 4.1 years, were offered continuous positive airway pressure and medical treatments for severe obstructive sleep apnoea whilst surgery was paused during the coronavirus disease 2019 pandemic. Both children failed to establish continuous positive airway pressure therapy because of ongoing disturbed sleep on ventilation, and they proceeded to adenotonsillectomy. Sleep-Related Breathing Disorder scale scores improved following surgical intervention.

Continuous positive airway pressure therapy is poorly tolerated in children with severe obstructive sleep apnoea secondary to adenotonsillar hypertrophy. Surgery remains the most appropriate treatment.

There is limited understanding of treatment pathways for paediatric sleep-disordered breathing. This study explored current UK pathways and what is important to well-being for parents and children.

The study comprised in-depth qualitative interviews (n = 22) with parents of children (2–9 years) with symptoms of sleep-disordered breathing referred to a regional ENT clinic (n = 11), general practitioners who might refer these children to ENT (n = 5) and hospital doctors involved in treating these children (n = 6). Interviews were audio recorded, transcribed verbatim, anonymised and analysed thematically.

General practitioners rarely identify seeing children with sleep-disordered breathing; conversely hospital doctors identify unsuspected issues. Parents are worried their child will stop breathing, but routes to referral and diagnosis are not straightforward. Modern technology can aid investigation and diagnosis. Patient weight is an issue for general practitioners and hospital doctors. Adenotonsillectomy is the treatment of choice, and information on paediatric sleep-disordered breathing is needed.

Guidelines for the management of paediatric sleep-disordered breathing are needed.

Adenotonsillectomy is a recognised treatment for paediatric obstructive sleep apnoea. Recent literature highlights the need to assess outcomes in the extremely obese subpopulation. This study reviewed the efficacy of adenotonsillectomy performed in patients with extreme obesity.

A retrospective analysis of attendees at a tertiary paediatric obesity clinic was performed, identifying patients with a body mass index z-score equal to or more than three who had undergone adenotonsillectomy for obstructive sleep apnoea. Electronic patient records, including respiratory polygraphy, were analysed.

Nine patients met the study criteria. All required nocturnal non-invasive ventilation pre-operatively. Mean age at referral was 6.9 years, and average age of non-invasive ventilation commencement was 7.8 years. Post-operatively, 8 patients (89 per cent) required non-invasive ventilation with evidence of post-operative obstructive sleep apnoea.

In extreme obesity, adenotonsillectomy does not prevent the need for non-invasive ventilation. Management of this patient group requires treatment of obesity alongside potential surgical intervention. Poor efficacy in treating obstructive sleep apnoea may influence the decision to proceed with adenotonsillectomy.

There is limited understanding amongst patients and parents of paediatric patients regarding adenoidectomy. Most patients access health-related information online. The aim of this study was to assess the suitability of online information on adenoidectomy.

The term ‘adenoid’ was used to search Google, and the first 50 websites identified were screened. For each website, the readability and quality were assessed.

Of the 41 websites that met the inclusion criteria, the mean readability scores corresponded to ‘difficult to read’ and university-level reading categories. For the quality of the websites, the mean score corresponded to ‘fair’ with 39 per cent of the websites containing either ‘poor’ or ‘very poor’ quality data. The ENT UK information is one of the most readable and reliable online resources.

The online information on adenoidectomy is largely set at an inappropriate readability level and of variable quality. Surgeons should consider assisting their patients with online searches regarding adenoidectomy.

Tonsillectomy and adenoidectomy have been among the most commonly performed procedures in children for approximately 100 years. These procedures were the first for which unwarranted regional variation was discovered, in 1938. Indications for these procedures have become stricter over time, which might have reduced regional practice variation.

This paper presents a historical review on practice variation in paediatric tonsillectomy and adenoidectomy rates. Data on publication year, region, level of variation, methodology and outcomes were collected.

Twenty-one articles on practice variation in paediatric tonsil surgery were included, with data from 12 different countries. Significant variation was found throughout the years, although a greater than 10-fold variation was observed only in the earliest publications.

No evidence has yet been found that better indications for tonsillectomy and adenoidectomy have reduced practice variation. International efforts are needed to reconsider why we are still unable to tackle this variation.

This study aimed to analyse social, health and environmental factors associated with the development of chronic otitis media by age nine.

This was a prospective, longitudinal, birth cohort study of 6560 children, reviewed at age nine. Chronic otitis media defined as previous surgical history or video-otoscopic changes of tympanic membrane retraction, perforation or cholesteatoma. Non-affected children were used as the control group.

Univariate analysis demonstrated an association between chronic otitis media and otorrhoea, snoring, grommet insertion, adenoidectomy, tonsillectomy, hearing loss, abnormal tympanograms and preterm birth. Multivariate analysis suggests many of these factors may be interrelated.

The association between chronic otitis media and otorrhoea, abnormal tympanograms and grommets supports the role of the Eustachian tube and otitis media (with effusion or acute) in the pathogenesis of chronic otitis media. The role of snoring, adenoidectomy and tonsillectomy is unclear. Associations suggested by previous studies (sex, socioeconomic group, parental smoking, maternal education, childcare, crowding and siblings) were not found to be significant predictors in this analysis.

Velopharyngeal insufficiency is the inability to close the velopharyngeal port during speech and swallowing, leading to hypernasal speech and food regurgitation.

This study aimed to explore the aetiological factors contributing to the development of velopharyngeal insufficiency in a non-cleft paediatric population, especially following adenoidectomy.

A retrospective case review was conducted of all children without a known cleft palate, born between 2000 and 2013, who were referred to a tertiary cleft centre with possible velopharyngeal insufficiency.

The data for 139 children diagnosed with velopharyngeal insufficiency following referral to the cleft centre were analysed. Thirteen patients developed the condition following adenoidectomy; only 3 of these 13 had a contributing aetiological factor.

Velopharyngeal insufficiency is a rare but significant complication of adenoidectomy. The majority of patients who developed velopharyngeal insufficiency following adenoidectomy did not have an identifiable predisposing factor. This has important implications for the consent process and when planning adenoidectomy.

To compare endoscopic assisted powered adenoidectomy with conventional curettage adenoidectomy.

A randomised controlled trial was conducted at a tertiary care teaching hospital. Fifty patients with a symptom complex pertaining to adenoid hypertrophy and requiring adenoidectomy were chosen and divided into 2 groups of 25 each. Patients in group A underwent conventional curettage adenoidectomy and those in group B underwent endoscopic assisted powered adenoidectomy. Comparison was based on the parameters of surgical time, intra-operative bleeding, post-operative pain and completeness of adenoid removal.

The surgical time was significantly longer with the powered instrument. Mean blood loss was greater in the powered group, but was statistically insignificant. The powered procedure fared significantly better, with lower pain scores and more instances of complete tissue resection.

A curved microdebrider blade can be used safely and precisely for adenoidectomy under endoscopic vision. It enables complete resection of adenoid tissue. This method also proves to be an excellent teaching aid.

This study assessed the preferences of surgeons regarding surgical modalities used for adenotonsillectomy, and determined anxiety levels related to the adenotonsillectomy procedure.

A 10-question survey created by the authors was administered to 413 ENT specialists attending the 4th Congress of Otorhinolaryngology Head and Neck Surgery, held in October 2017 in Barcelona, Spain.

Cold knife dissection was the preferred surgical modality for both adenoidectomy and tonsillectomy. Most participants reported encountering one to five patients with post-tonsillectomy bleeding throughout their entire career. The mean anxiety levels during surgery and the 10-day post-operative period were 3.39 ± 2.14 and 4.18 ± 2.63, respectively (p < 0.05). There was a significant negative correlation between anxiety level and surgeon's experience (p < 0.05).

Cold dissection is still the preferred surgical modality for adenotonsillectomy, while both suture ligation and electrocautery are used for haemostasis. Paediatric adenotonsillectomy is likely to generate anxiety in ENT surgeons, and the possibility of secondary post-tonsillectomy bleeding increases the anxiety levels of surgeons in the post-operative period.

To compare conventional cold curettage adenoidectomy with endoscopic assisted coblation adenoidectomy in terms of operative time, primary blood loss, post-operative residual tissue and post-operative pain.

This prospective non-randomised study was carried out on 60 patients aged 5–12 years. One group underwent conventional cold curettage adenoidectomy and the other underwent endoscopic assisted coblation adenoidectomy, with 30 patients per group.

Mean operation duration was significantly higher for endoscopic assisted coblation adenoidectomy. Mean blood loss was 44.33 ml in conventional cold curettage adenoidectomy and 32.47 ml in endoscopic assisted coblation adenoidectomy. The pain grade was significantly lower in endoscopic assisted coblation adenoidectomy. Forty per cent of patients who underwent conventional cold curettage adenoidectomy had adenoid tissue post-surgery, while it was completely absent in endoscopic assisted coblation adenoidectomy patients.

Coblation adenoidectomy has significant advantages over conventional adenoidectomy in terms of reduced blood loss, no post-operative residual tissue and lower pain grade on day 1 after surgery.

This study aimed to evaluate post-adenoidectomy quality of life in children with refractory chronic rhinosinusitis.

A prospective interventional study of children aged 4–12 years with chronic refractory rhinosinusitis was conducted. A total of 60 children completed follow up. Nasal endoscopy and non-contrast computed tomography of the paranasal sinuses were performed, and both symptoms and their effects on patient quality of life pre- and post-adenoidectomy were evaluated.

The most frequent symptoms were nasal obstruction, cough, fever and fatigue, which were experienced by 100 per cent, 90 per cent, 85 per cent and 81.7 per cent of children, respectively. Nasal endoscopy showed oedema and discharge were present in all children. A statistically significant post-operative improvement in sinus and nasal quality of life was seen in 53 children (88.3 per cent).

Adenoidectomy is a simple, first-line surgical procedure for managing paediatric chronic rhinosinusitis refractory to maximal medical therapy and leads to an improved quality of life.

To systematically search for studies reporting outcomes for adenoidectomy alone as a treatment for paediatric obstructive sleep apnoea and use the data to perform a meta-analysis.

Nine databases, including PubMed and Medline, were systematically searched through to 1 April 2016. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement was followed.

A total of 1032 articles were screened and 126 full texts were reviewed. Three paediatric studies (47 patients) reported outcomes. Overall, apnoea–hypopnoea index values decreased from 18.1 ± 16.8 to 3.1 ± 5.5 events per hour (28 patients). Random-effects modelling demonstrated a mean difference of −14.43 events per hour (I2 = 23 per cent (low inconsistency)). The apnoea–hypopnoea index standardised mean difference was −1.14 (large magnitude of effect). The largest reduction in apnoea–hypopnoea index was observed in children aged less than 12 months (reduction of 56.6−94.9 per cent). Lowest oxygen saturation values improved from 80.0 ± 9.5 to 85.5 ± 6.0 per cent (13 children).

Adenoidectomy alone has improved obstructive sleep apnoea in children, especially in those aged less than 12 months; however, given the low number of studies, isolated adenoidectomy remains an area for additional research.

Children with obstructive sleep apnoea commonly undergo adenotonsillectomy as first-line surgical treatment. This paper aimed to investigate whether this intervention was associated with weight gain after surgery in the paediatric population with obstructive sleep apnoea.

Two independent researchers systematically reviewed the literature from 1995 to 2014 for studies on patients who underwent adenotonsillectomy with weight-based measurements before and after surgery. The databases used were Ovid Medline, Embase and PubMed.

Six papers satisfied all inclusion criteria. Four of these papers showed a significant weight increase and the others did not. The only high quality, randomised, controlled trial showed a significant increase of weight gain at seven months follow up, even in patients who were already overweight before their surgery.

The current evidence points towards an association between adenotonsillectomy and weight gain in patients with obstructive sleep apnoea in the short term.

This study aimed to measure changes in disease-specific quality of life in children following tonsillectomy or adenotonsillectomy.

A multicentre prospective cohort study was performed involving seven ENT departments in England. A total of 276 children entered the study over a 2-month period: 107 underwent tonsillectomy and 128 adenotonsillectomy. Forty-one children referred with throat problems initially managed by watchful waiting were also recruited. The follow-up period was 12 months. Outcome measures were the T14, parental impressions of their child's quality of life and the number of days absent from school.

One-year follow-up data were obtained from 150 patients (52 per cent). The mean baseline T14 score in the non-surgical group was significantly lower (T14 = 23) than in the tonsillectomy group (T14 = 31) or the adenotonsillectomy group (T14 = 35; p < 0.001). There was a significant improvement in the T14 scores of responders in all groups at follow up. The effect size was 1.3 standard deviations (SD) for the non-surgical group, 2.1 SD for the tonsillectomy group and 1.9 SD for the adenotonsillectomy group. Between-group differences did not reach statistical significance. A third of children in the non-surgical group underwent surgery during the follow-up period.

Children who underwent surgical intervention achieved a significant improvement in disease-specific quality of life. Less severely affected children were managed conservatively and also improved over 12 months, but 1 in 3 crossed over to surgical intervention.

To review the literature on the outcomes of ENT operations in order to assess whether ENT operations are effective.

The value of evidence-based medicine in relation to ENT was appraised, as was the perception of effectiveness. Literature on common ENT operations, including grommet insertion, tonsillectomy and adenoidectomy, and correction of the nasal septum, was evaluated.

When evaluating the effectiveness of ENT operations, the patient's overall condition and improvements after surgery should be measured. Objective and subjective factors should both be considered as good evidence, especially with the increasing role that evidence-based medicine plays in decisions of whether to operate. The literature review provides evidence that ENT operations are effective.

This study aimed to explore adenoid regrowth after transoral power-assisted adenoidectomy down to the pharyngobasilar fascial surface.

Transoral adenoidectomy down to the pharyngobasilar fascia surface was performed on 39 patients under endoscopic guidance, using a power-assisted system. The operation time, amount of blood loss and iatrogenic injury, presence of complications, and success and regrowth rates were recorded to assess the feasibility, safety and effectiveness of our surgical technique.

In this adenoidectomy procedure, the pharyngobasilar fascia was left intact. The estimated blood loss was 5–50 ml (mean 15 ml), and the success rate was 97.3 per cent. Early complications occurred in 2.3 per cent of patients, while no long-term complications occurred in the cohort. No regrowth was found in the follow-up assessments, which were performed for 18–36 months after surgery.

Adenoid regrowth was rare after adenoidectomy down to the pharyngobasilar fascial surface. The pharyngobasilar fascia can therefore be considered a surgical boundary for adenoidectomy.

Adenoidectomy and tonsillectomy are the oldest surgical procedures. The neutrophil-to-lymphocyte ratio is an inflammatory marker. This study aimed to investigate neutrophil-to-lymphocyte ratios in chronic tonsillitis patients and to determine whether this ratio reflects the pre- and post-operative inflammatory status in these patients.

Patients and healthy individuals were assigned to four groups: the adenoid hypertrophy, adenotonsillar hypertrophy, chronic tonsillitis and control groups. The neutrophil-to-lymphocyte ratio was calculated for each patient before surgery and one month post-surgery. Pre- and post-operative white blood cell, neutrophil and lymphocyte counts and neutrophil-to-lymphocyte ratios were compared both within and between groups.

Pre- and post-operative neutrophil-to-lymphocyte ratios were significantly higher in the chronic tonsillitis group than in the adenoid hypertrophy and adenotonsillar hypertrophy groups (p < 0.01 and p < 0.05, respectively). In the chronic tonsillitis group, post-operative neutrophil-to-lymphocyte ratios were significantly lower than pre-operative ratios (p = 0.045). The pre-operative neutrophil-to-lymphocyte ratio was significantly higher in the chronic tonsillitis group than in the adenoid hypertrophy, adenotonsillar hypertrophy and control groups (p = 0.000). In contrast, there was no significant difference in post-operative neutrophil-to-lymphocyte ratios among all groups (p = 0.584).

The neutrophil-to-lymphocyte ratio measurement can be used in chronic tonsillitis patients as an effective auxiliary method for determining the necessity and timing of tonsillectomy and post-operative follow up, thereby helping prevent complications due to delayed or inadequate treatment.

Post-operative high dependency unit beds are often requested for patients undergoing adenotonsillectomy for obstructive sleep apnoea. This study evaluated the utilisation of high dependency unit beds for such cases at our institution, a paediatric tertiary referral centre.

A retrospective case note review of patients admitted to the high dependency unit following adenotonsillar surgery for obstructive sleep apnoea, over a two-year period, was performed.

Sixty-six cases were identified. Thirty-nine patients underwent pre-operative overnight pulse oximetry; of these, 30 patients had desaturations noted. Seventeen patients had significant post-operative desaturations. These were predicted in all 11 patients who had undergone pre-operative pulse oximetry. The remaining six had not undergone pre-operative pulse oximetry. Nineteen patients required high dependency unit care; eight had experienced post-operative desaturations.

High dependency unit care may be required following adenotonsillectomy for obstructive sleep apnoea. In this study, pre-operative overnight pulse oximetry had 100 per cent sensitivity in predicting post-operative desaturations, and may therefore aid the appropriate utilisation of high dependency unit beds for patients undergoing adenotonsillectomy for obstructive sleep apnoea.

Adenoidectomy is often carried out in children for conditions such as nasal obstruction, otitis media with effusion, and obstructive sleep apnoea. Traditionally, it is performed as a blind procedure with a St Clair Thomson curette. An acceptable alternative technique is suction diathermy adenoidectomy. This study aimed to ensure that the complication rate of this latter technique was within published rates and national guidelines.

A retrospective case note review was conducted, and information regarding surgery, indications and complications was collected.

Post-operative haemorrhage was recorded for 2 of 121 patients (at days 10 and 11 post-operatively): 1 returned to the operating theatre and the other was managed conservatively. Two patients were diagnosed with infection post-operatively and managed with oral antibiotics. A further four patients re-presented with pain; in all cases, this was recorded as secondary to tonsillar fossa infection, rather than being pain related to adenoidectomy.

Given the rare but serious potential complications, the authors support National Institute for Health and Clinical Excellence guidance, which recommends that only surgeons with specific training perform this technique. By using the standard procedures for clinical governance, it is possible to ensure safe practice of even little-used techniques.
