Otorhinolaryngological Management in Taiwanese Patients with Mucopolysaccharidoses.

Background: Mucopolysaccharidoses (MPSs) are lysosomal storage disorders wherein glycosaminoglycans accumulate because the enzymes that degrade them are insufficient. The earliest symptoms, which are the main reasons for seeking consultation, are otorhinolaryngological and commonly occur in MPS I, II, IV, and VI. This retrospective study aimed to determine the occurrence of otorhinolaryngological manifestations in MPS patients in Taiwan and to analyze the prognosis of surgical intervention, including its effect on symptoms.Methods: We reviewed 42 patients (30 males and 12 females), with a median age of 20.5 years, who had MPS (16.7% type I, 35.7% type II, 19.0% type IIIB, 21.4% type IVA, and 7.2% type VI). The following otorhinolaryngological manifestations were collected: annual number of upper respiratory tract infections (URTIs) and otitis media with effusion (OME) episodes, adenoid size, tonsillar size, and apnea-hypopnea index (AHI).Results: Among 42 patients, we found recurrent otitis media in 42.9% of the patients, hearing loss in 83.3% (mixed: 52.4%, conductive: 21.4%, and sensorineural: 9.5%), frequent URTIs in 47.6%, and obstructive sleep apnea syndrome in 35.7%. Moreover, 76% of the patients underwent ear, nose, and throat (ENT) surgery, including adenoidectomy, tonsillectomy, tympanostomy with ventilation tube insertion, tracheotomy, and supraglottoplasty.Conclusions: MPS patients had a high incidence of ENT problems. ENT surgery reduced the severity of hearing loss, degree of symptoms related to upper airway obstruction, and severity of respiratory tract and otological infections of patients with MPS.

Assessment of Friedman Classification by Measuring Actual Tonsil Size During Surgery

Background and Objectives: Adenotonsillar enlargement is a common cause of pediatric illnesses, including obstructive respiratory disease and recurrent airway infection. The current tonsil grading systems evaluate tonsil size, but the correlation with actual tonsillar size in a clinical setting has not been established.Materials and Method: Between May and July of 2018, we recruited 31 children who underwent adenotonsillectomy with no major craniofacial abnormalities. The actual size of the palatine tonsils, the long (L1) and short (S1) axes of the tonsil beyond the anterior pillar, and the real axes (L2 and S2) after tonsil extraction from the fossa were measured during surgery. Adenoid size was determined by measuring the adenoid-nasopharynx (AN) ratio through lateral view x-ray of the neck.Results: Though S1 was related to the Friedman scale (p<0.001), measured real axes were not (L2: p=0.058, S2: p=0.056). Also, adenoid size and AN ratio did not relate statistically to the Friedman scale (p=0.565). One of the measured real tonsil size parameters (S2) was related to AN ratio (p=0.048).Conclusion: For pediatric patients undergoing tonsillectomy and adenoidectomy, the Friedman grading scale based on physical examination may not reflect the actual size of the tonsils. Therefore, for children with obstructive sleep disorder or recurrent tonsillitis, intraoperative measurement of tonsil size can be helpful.

Assessment of Predicting Factors for Pediatric Sleep Disordered Breathing

The aim of this study was to evaluate the association between various predicting tools and Apnea-Hypopnea Index (AHI) to identify children with sleep disordered breathing (SDB). From 5 to 10 years old who came for orthodontic counseling, 61 children, whom had lateral cephalograms, pediatric sleep questionnaire (PSQ) records, and portable sleep monitoring results, were included in this study. A total of 17 measurements (11 distances and 6 angles) were made on lateral cephalograms. The measurements of lateral cephalograms, PSQ scales and portable sleep monitoring results were statistically analyzed. 49 of 61 (80%) patients showed AHI > 1, which suspected to have SDB and their mean AHI was 2.75. In this study, adenoid size (A/N ratio), position of the hyoid bone from mandibular plane, gonial angle, and PSQ scale were related to a higher risk of pediatric SDB. Also, oxygen desaturation index (ODI) and snoring time from sleep monitoring results were statistically significant in children with SDB using Mann-Whitney test (<i>p</i> ＜ 0.05).<br/>In conclusion, evaluation of hyoid bone position, adenoidal hypertrophy, gonial angle in lateral cephalogram, and PSQ scale was important to screen out potential SDB, especially in children with frequent snoring.

Incidence of cure and residual obstructive sleep apnea in obese children after tonsillectomy and adenoidectomy stratified by age group

ObjectivesCurrent clinical guidelines by the American Academy of Pediatrics recommends adenotonsillectomy (T&A) as the first-line treatment for pediatric OSA. However, obese children experience a decreased incidence of cure from T&A compared to non-obese children, with obesity increasing risk of residual post-operative OSA by up to 3.7-fold. In addition to obesity, increased age has also been linked to more severe baseline OSA, among other factors. In this study, we examined how age effects the post-operative outcome in obese children with OSA. MethodsA retrospective chart review was performed to assess post-operative T&A polysomnography outcomes of obese children. Inclusion criteria included patients who were 17 years old and younger, underwent T&A, were obese and had both pre- and post-operative sleep studies. The patients were split into 3 different groups based on their age: Group 1 (0–6 years old), Group 2 (7–11 years old), and Group 3 (12–17 years old). Results55 patients were included in the study: 13 in Group 1, 20 in Group 2, and 22 in Group 3. For Groups 1, 2, and 3 respectively, data averages were BMI percentile 99.20, 98.49, and 98.92 (P = 2.77); z-score 2.79, 2.36, and 2.45 (P = 0.026), tonsil size 3.17, 3.15, and 3.23 (P = 0.898), adenoid size 2.42, 2.05, and 1.77 (P = 0.015), time between the preoperative and postoperative PSG 179, 240, and 202 days (P = 0.481), and time from surgery to postoperative PSG 126, 170, and 127 days (P = 0.544). The average preoperative oAHI was 52.56, 41.23, and 43.49 (P = 0.732), post-operative oAHI was 1.94, 4.79, and 4.44 (P=.417); and change in oAHI was 50.62, 36.44, and 39.25 (P = 0.617). When comparing the age group of 0-6-year-olds to the older remaining patients, the post-operative oAHI was the only variable to show a significant difference between the two-groups with a P value of 0.038. The percentage of patients with post-operative resolution of OSA (oAHI<2), mild, moderate, and severe OSA, respectively, were 53%, 29%, 9%, and 9% for all patients, 70%, 23.1%, 7%, and 0% for group 1; 50%, 35%, 5%, and 10% for group 2; and 45%, 27%, 13%, and 13% for group 3. The percent of the patients requiring post-surgical nighttime airway support were 18%, 7%, 15%, and 26% for Groups All, 1, 2, and 3, respectively. ConclusionWe found that despite having the highest rates of obesity and the most severe OSA, obese patients under 7 years old performed better following T&A, with greater cure rate, overall reduction of oAHI, and decreased need for post-surgical nighttime airway support.

Inverse Relationship between Adenoid Size and Asthma or Atopy in Children: A Preliminary Study

Background and Objectives One of the most common surgical procedures in children is adenoidectomy, but the causes of adenoid hypertrophy are not fully understood. Some studies have found that allergies can be a risk factor for adenoid hypertrophy, asthma being one of these allergic diseases. This study aimed to investigate the relationship between adenoid size and asthma in a group of children.Subjects and Method This study reviewed a total of 2063 pediatric patients with or without atopy and asthma who visited the Otorhinolaryngology and Pediatric unit at a tertiary medical center from January 2011 to June 2016. We classified these patients into 4 groups according to the presence of asthma or atopy and randomly selected 100 patients from each group (to a total of 400 pts): group 1 (asthma-, atopy-); group 2 (asthma-, atopy+); group 3 (asthma+, atopy-) and group 4 (asthma+, atopy+). The presence of allergic sensitization (atopy) was evaluated by CAP test and total IgE. Asthma was diagnosed according to the diagnosis criteria in the Korean guideline for asthma. Adenoid size was evaluated with the adenoidal-nasopharyngeal ratio (A/N ratio) by the adenoid view.Results The four groups did not differ from each other significantly in age or sex. There was a negative correlation between adenoid size and atopic and asthmatic condition. Group 1 had a significantly larger A/N ratio than the other groups (group 1=0.534±0.138; group 2=0.469± 0.140; group 3=0.476±0.135; group 4=0.482±0.128, &lt;i&gt;p&lt;/i&gt;&lt;0.05). However, group 4 showed nearly identical results to groups 2 and 3, despite the combination of asthma and atopy in group 4.Conclusion Large adenoids were negatively associated with atopy and asthma. This finding may be explained by a decrease in adenoid stimulation by nasal obstruction and a difference in the immune system, including allergic immune reactions. Further studies are needed.

Otitis media with effusion is not a sterile inflammatory process: scanning electron microscope evidence.

We aimed to demonstrate whether chronic otitis media with effusion (OME) is a sterile condition or biofilms-related disease through direct visualization of middle ear mucosa by Scanning electron microscopy (SEM) and culture of the effusion. This case-control study included 60 children in two groups; the case group included 50 patients undergoing ventilation tube insertion (VTI) for Chronic OME (COME), and the control group included ten patients undergoing cochlear implantation (CI) surgery presenting normal middle ear mucosa. Biopsies from both groups' middle ear mucosa were evaluated for biofilm formation using scanning electron microscopy (SEM). Middle ear effusion (MEE) samples from COME patients were cultured on blood agar to detect and identify any bacterial growth. The adenoid size was evaluated and correlated to the biofilm formation in COME patients. There was a significant difference between case and control groups regarding biofilm formation (p-value < 0.001*). Biofilm was evident in 84% of the COME patients (cases group) and absent in the control group. Only 12 COME patients (24%) had positive MEE culture, however, 76.2% of patients with biofilm had a negative culture. Streptococcus pneumonia was the most common otopathogen found either alone or combined with other otopathogens. There was a significant negative correlation between adenoid size and biofilm grade among the studied patients. The visual identification of middle ear biofilms indicated their role in chronic OME. Middle ear biofilms need to be expected in children with OME, especially those who do not need adenoid surgery.

Snoring toddlers with and without obstructive sleep apnoea differed with regard to snoring time, adenoid size and mouth breathing.

The difficulty of assessing the likelihood of obstructive sleep apnoea (OSA) in children who snore without full-night polysomnography is widely recognised. Our aim was to identify features that were characteristic of two-year-old children with OSA and evaluate whether this information could be used to assess the likelihood of OSA. The study was carried out as part of the Child-Sleep Project, a longitudinal birth cohort study of children born at Tampere University Hospital, Finland. This part of the study focused on the children in the cohort who snored and was carried out between 2013 and 2015. The primary outcomes were measured using parental questionnaires, polysomnography and clinical examinations. In total, 52 children participated at a mean age of 27months (range 23-34). Of these, 32 (44% male) snorers and 20 (70% male) controls. The most significant findings were that children who had OSA demonstrated longer snoring time (P=.003), a greater tendency for mouth breathing (P=.007) and bigger adenoid size (P=.008) than snorers without OSA. Snoring time, adenoid tissue size and mouth breathing were important features that identified the likelihood of OSA in snoring toddlers.

Inflammatory fibrous hyperplasia in pediatric dentistry due to deleterious habit: case report

This paper reports the clinical case of a pediatric dentistry patient, presenting a correlation between non-nutritive suction and inflammatory fibrous hyperplasia. A 10-year-old female patient attended the Pediatric Dentistry Clinic of the Araçatuba Dental School-Brazil (FOA/UNESP) with her mother, who reported a "little ball under the upper lip" of the daughter, observed three months before, with gradual increase. The clinical examination revealed poor positioning of tooth 21 and a fibrous hyperplasia at 2 cm from the upper region of the respective tooth. A presumptive diagnosis of inflammatory fibrous hyperplasia was established. The proposed treatment was lesion excision, fabrication of a Hawley appliance for repositioning of tooth 21 and counseling on the need to cease the deleterious digital sucking habit. We conclude that elimination of the traumatic agent is fundamental for therapeutic success, in addition to surgical removal.Descriptors: Hyperplasia; Fingersucking; Habits.ReferencesEspinoza-Zapata M, Loza-Hernández G, Mondragón-Ballesteros R.

Management of Pediatric Chronic Rhinosinusitis

Chronic pediatric rhinosinusitis is a common entity, with an annual incidence of 4% in the US schoolchildren’s population. The predominant contributing factor in younger children is adenoid pathology and in older children, allergic rhinitis. Recent research on sinus microbiome, biofilm, inflammatory response, and therapeutic alternatives is providing new insights in this prevalent disease. Adenoid size does not correlate with the severity of the disease suggesting that it is due to the biofilms observed in both adenoiditis and hypertrophic adenoids. There is new consensus among the experts on the definition and clinical diagnosis of pediatric chronic rhinosinusitis (PCRS). In PCRS, inflammation is mediated by helper T lymphocyte type 2 with limited glandular hyperplasia or fibrosis observed histologically. Both innate and adaptive immunity contribute to the heterogeneous inflammatory pathogenesis of PCRS that is driven by genetic, environmental, and microbiome factors. Medical treatment includes nasal hygiene, anti-inflammatory, and antibiotic therapy. When medical treatment fails, adenoidectomy is the surgical treatment of choice in children less than 6 years old, adenoidectomy plus possible endoscopic endonasal surgery (EES) between ages 6 and 12, and EES for children 12 and older. Balloon sinuplasty has been reported to be effective between 70 and 80% in older children. This review focuses on the most recent PCRS consensus statements, novel research in histopathology and microbiome, and the evolving medical and surgical therapeutic options for this challenging disease.

Study on the correlation between OSAS and thoracic deformity in children: A retrospective single-center study in China

ObjectiveTo evaluate the correlation between obstructive sleep apnea syndrome (OSAS) and the development of thoracic deformity in Children. MethodsA retrospective analysis was performed with the medical records of 39 pediatric OSAS patients with thoracic deformity and matching 39 without thoracic deformity as control group between January 2015 and June 2019. The contrast was performed with age, gender, height, weight, body mass index (BMI), apnea/hypopnea index (AHI), the lowest oxyhemoglobin saturation (loSpO2)at night, tonsil and adenoid size, Alkaline phosphatase (ALP)and trace elements and metals between two groups. ResultsBMI, AHI, the lowest SpO2, Phosphorus and Zinc were the risk factors of thoracic deformity. Age, gender, disease history, the size of tonsil and adenoid, ALP and other trace elements were no significant difference occurred between two groups. ConclusionOSAS characterized by apnea and hypoxia which are caused by narrow upper airway may be one cause of thoracic deformity in children. Pediatricians, thoracic and otolaryngologic surgeons should be alert to OSAS when thoracic deformities are diagnosed in children.

Low vitamin D levels and frequencies of regulatory T cells (Tregs) are associated with adenotonsillar hypertrophy in children

ObjectiveTo evaluate the levels of vitamin D and the frequencies of regulatory T cells (%Tregs) in children undergoing adenotonsillectomies (T&As) and their controls. MethodsWe prospectively collected data from 130 children aged from 2 to 14 years old undergoing T&As and 60 undergoing unrelated elective procedures from November 1, 2015 to December 20, 2017 at the First Affiliated Hospital of Anhui Medical University. Demographic and disease specific data was obtained in addition to blood samples for the measurement of 25-hydroxy (OH)-vitamin D, interleukin-10 and %Tregs. ResultsAmong the 130 patients undergoing T&As who had 25(OH) vitamin D levels measured, 40.8% were vitamin D deficient (25(OH) vitamin D < 20 ng/mL), 42.3% were insufficient (20 ng/mL < 25(OH) vitamin D < 30 ng/mL), only 16.9% were sufficient (25(OH) vitamin D > 30 ng/mL). Compared with the control group, children undergoing adenotonsillectomies exhibited a significant decrease in the level of serum 25(OH) vitamin D and %Tregs (p < 0.01, p < 0.01). The level of 25(OH) vitamin D and % Tregs did not correlate to parameters like BMI, age, sex in the children undergoing T&As. The lower Vitamin D levels were related to higher OSA-18 scores (Pearson correlation, r = −0.476, p < 0.01), tonsil size (Spearman rank correlation, r = −0.563)and adenoid size (Spearman rank correlation, r = −0.291). In the different vitamin D concentration groups, the mean values of %Tregs were not equal (ANOVA, F = 7.389, p = 0.001). ConclusionChildren undergoing T&As have a lower level of 25(OH) vitamin D and %Tregs. Low 25(OH) vitamin D levels were related to higher OSA-18 scores and greater lymphoid tissue size rather than sex, age, increased BMI. Vitamin D and Treg cells are associated with adenotonsillar hypertrophy.

Correlative Multicentric Analysis of Dimensions of Nasopharynx and Adenoid Size, and its Burden in Otitis Media with Effusion: An Indian Scenario.

Diseases of adenoids are commonly observed in children. It indirectly leads to pathology in the middle ear cleft. It has been demonstrated both by radiological techniques and middle ear pressure studies that adenoids can and do obstruct the Eustachian Tube. The Adenoid-Nasopharyngeal Ratio (ANR), can offer a simple arithmetic measure of nasopharyngeal obstruction. Coupled with tympanometry, it also predicts the degree to which the middle ear is affected. Multicentric study done at two centres in India. 230 patients were studied. Children were in the age group of 5-14years. The nasopharyngeal and adenoid dimensions were measured separately using the Fujioka method. The adenoid-nasopharyngeal ratio was derived by the arithmetic method. All patients were also subjected to tympanometry. ANR decreased from 0.728 to 0.663 with an increase in age from 5 to 12years. ANR between 0.701-0.800 had maximum number of Type B (140) and Type C (71) Tympanogram whereas between 0.801 and 0.900, all Tympanogram were found to be of Type B or Type C with none belonging to Type A. Using ANR and Tympanometry, the effects of the adenoids on the middle ear can be quantified indirectly. Both these modalities are easily available, economical, safe and can be performed at the Out Patient Level. This aids in timely and appropriate management thus preventing discomforting symptoms caused by the adenoids locally and also the morbidity caused to the middle ear in the long term.

The microbiome of pediatric patients with chronic rhinosinusitis.

This study aimed to compare the microbiota of pediatric patients with chronic rhinosinusitis (CRS) who are undergoing adenoidectomy to treat their disease with that of healthy control patients. Patients undergoing adenoidectomy-only for obstructive sleep apnea (n = 50) and CRS (n = 37) were recruited. Preoperative 22-item Sino-Nasal Outcome Test (SNOT-22) or Sinus and Nasal Quality of Life Survey (SN-5) were collected. Each patient had samples collected from their nasopharynx (adenoid bed) and nasal cavity (sinus) at the onset of surgery. 16S ribosomal ribonucleic acid (rRNA) gene sequencing was subsequently performed to obtain per sample taxonomic abundances. Statistical analyses included permutational multivariate analysis of variance (PERMANOVA), alpha (within sample) diversity measures, and changes in taxonomic abundance. Moraxella was the most abundant organism. Nasopharyngeal swabs demonstrated higher alpha diversity compared to the nasal cavity. The diversity was not different based on CRS vs obstructive history. There was an increase in diversity with increasing age, and eczema contributed to a greater difference in diversity between the nasopharynx and nasal cavity. Diversity was not affected by adenoid size; however, use of nasal steroids, inhaled steroids, and antihistamines influenced diversity in both the nasopharynx and nasal cavity. Nasopharyngeal samples were higher in relative abundance for Fusobacterium, Prevotella, Porphyromonas, and Campylobacter compared to the nasal cavity. The nasopharynx and nasal cavity differed in both microbiota composition and diversity. In contrast, no significant difference in composition or diversity were found in CRS vs control patients. Ecological changes in the nasopharyngeal and sinus site may contribute to the etiology for adenoid hypertrophy in both healthy controls and CRS patients.

NASOPHARYNGOSCOPY VERSUS PLAIN RADIOGRAPHY IN ADENOID SIZE ASSESSMENT

This is a prospective comparative study of adenoid size assessment by using radiography versus nasopharyngoscopy using examination of the adenoid under general anesthesia (GA) as a standard method. This study was conducted on 35 children presented with signs and symptoms of adenoid hypertrophy. All patients were examined by both lateral radiograph view of the postnasal space and nasopharyngoscopy, then both results were compared. The results for small size adenoid can not be calculated because of small sample size. For medium sized adenoid, the sensitivity for radiography and nasopharyngoscopy are 36.36%, 54.54% respectively, the specificity was 47.36%, 84.21% respectively and the accuracy was 43.33%, 73.33% respectively. For large sized adenoid the sensitivity for radiography and nasopharyngoscopy was 38.89%, 83.33% respectively, the specificity was 100%, 66.66% respectively, and the accuracy was 63.33%, 76.66% respectively. In conclusion, nasopharyngoscopy is a simple, safe, repeatable, readily available at the ENT unit, with no radiation hazards, and with negligible trauma. Over all, nasopharyngoscopy has a higher sensitivity, specificity and accuracy than radiography.

Risk factors for residual mouth breathing in children who had completely resolved obstructive sleep apnea after adenotonsillectomy.

Adenotonsillectomy is the first-line treatment for pediatric obstructive sleep apnea (OSA). However, although completely resolved OSA after adenotonsillectomy, some children still showed persistence of mouth breathing. Therefore, we attempted to identify risk factors for residual mouth breathing in children with OSA after successful adenotonsillectomy. This study retrospectively enrolled children who underwent adenotonsillectomy as a treatment of OSA. Additionally, children who showed apnea-hypopnea index ≥ 1 on 1-year postoperative polysomnography or adenoid regrowth on one-year postoperative lateral cephalogram were excluded. The presence of allergic rhinitis, septal deviation, dentofacial abnormalities, the size of tonsil and adenoid was also evaluated in all enrolled children. Dentofacial abnormalities were defied as a high palatal arch, macroglossia, retrognathia, micrognathia, and overcrowding of teeth which assessed by dentists. A total of 62 children were enrolled (no residual mouth-breathing group, n = 18 and residual mouth-breathing group, n = 44) in this study. There were no significant differences in demographic factors, physical examination, and sleep parameters, except age and preoperative adenoid size. On the multiple logistic regression analysis, we found that older age, large adenoid size, and presence of dentofacial abnormalities significantly correlated with residual mouth breathing (adjusted coefficient estimates = 0.3890, 2.3611, and 2.8615, respectively) after successful adenotonsillectomy. Older age, large adenoid size, and presence of dentofacial abnormalities in children with OSA may be the risk factors for residual mouth breathing after successfully resolved OSA.

Pediatric Versus Adult Chronic Rhinosinusitis.

Pediatric and adult chronic rhinosinusitis (CRS) have some similarities but a number of differences. This article reviews the similarities and differences between pediatric and adult CRS. Rhinosinusitis is an inflammatory disease of the nose and the paranasal sinuses. In adults, inflammation in CRS without polyps (CRSsNP) mainly manifests with T-helper 1 lymphocytes while in CRS with polyps (CRSwNP) manifests with T-helper 2 lymphocytes and eosinophilic inflammation. In children, CRS inflammation manifests with neutrophils, macrophages, and lymphocytes. The associations between the ostiomeatal complex occlusion and CRS are revealed in adults but are not so evident in children. Although the relationship between the CRS and allergic rhinitis is still controversial, recent findings have shown an association between allergen sensitization and a specific group of adults with rhinosinusitis. Intranasal corticosteroids and saline constitute the first-line of medical treatment for both pediatric and adult rhinosinusitis. Low-dose macrolides are used for immunomodulatory activities and beneficial effects to adult patients with CRSsNP were demonstrated by recent meta-analyses. For surgical treatment, adenoidectomy is a key strategy to eradicate mature biofilms in pediatric CRS and effective in treating children with CRS regardless of the adenoid size. Although endoscopic sinus surgery has been proven to improve quality of life outcomes in adult CRS, it should be only considered in the pediatric CRS after failure of adenoidectomy. Pediatric and adult CRS are different in many aspects, including immunopathogenesis and management. Investigations should be considered in specific cases. After failure of medical treatments, endoscopic sinus surgery is recommended for adults, while adenoidectomy is primarily considered for children.

Feasibility study of determining a risk assessment model for obstructive sleep apnea in children based on local findings and clinical indicators

ObjectiveTo test a feasible and reliable model for diagnosing obstructive sleep apnea (OSA) in children, based on the clinically relevant parameters, in comparison to a polysomnography. MethodsA total of 94 children with the suspected underlying OSA were included in the analyses. An association between clinical parameters (modified Mallampati score, tonsil size, adenoid size, age, gender, and body mass index) and apnea-hypopnea index (AHI) obtained following an overnight polysomnography was assessed, and significant variables were incorporated in the logistic regression model. Also, the sensitivity and specificity calculations of the model with the inclusion of ROC curve analysis were performed. ResultsAll tee local clinical parameters were significantly associated with AHI (P < 0.001). The most significant correlation with AHI was shown with the modified Mallampati score (r = 0.723), following with tonsil size (r = 0.673), and adenoid size (r = 0.502). The sensitivity of the tested model was 84%, and specificity was 74%. ConclusionThis study derived a model based on the local clinical findings that significantly overlapped with the results of an overnight polysomnography, in diagnosing OSA in children.

Cold versus hot adenoidectomy: A prospective, randomized controlled trial

ObjectiveAdenoidectomy can be performed using the cold method (mainly adenoid curettes) or the hot method (suction diathermy). Both techniques have similar intra and postoperative outcomes. However, the long-term clinical outcome of improving sleep disorder symptoms has not been well established. The objective of this study was to compare outcomes of hot method and cold method adenoidectomy one year following the surgery. Study designA prospective, randomized, single-blinded study of children under age 16 years who underwent adenoidectomy during the years 2014–2017. Patients were randomized to hot or cold adenoidectomy techniques. SettingA tertiary health care referral center. Subjects and methodsThe final analysis included 58 children, mean age 5.9 years (range 1.2–15). The primary outcome was change in the Pediatric Sleep Questionnaire (PSQ) scores one month and one year after surgery. The secondary outcome was complication rate. ResultsClinical and demographic parameters were similar between the patients in the hot method group (n = 30) and the cold method group (n = 28). Adenoid size and estimated bleeding were similar between the groups. At one month after surgery, PSQ score was improved by a mean + 0.31 in the hot method group compared to +0.32 in the cold method group (p = 0.54). Improvement in PSQ scores was greater following hot than cold adenoidectomy at one year after surgery (+0.31 points vs. +0.22 points, p = 0.009). ConclusionHot adenoidectomy is associated with better outcome than the cold technique, as reflected by PSQ scores one year after the surgery.

Long-term Impact of Adenotonsillectomy on the Quality of Life of Children with Sleep-disordered breathing.

Introduction Adenotonsillectomy is the first-line treatment for obstructive sleep apnea secondary to adenotonsillar hypertrophy in children. The physical benefits of this surgery are well known as well as its impact on the quality of life (QoL), mainly according to short-term evaluations. However, the long-term effects of this surgery are still unclear. Objective To evaluate the long-term impact of adenotonsillectomy on the QoL of children with sleep-disordered breathing (SDB). Method This was a prospective non-controlled study. Children between 3 and 13 years of age with symptoms of SDB for whom adenotonsillectomy had been indicated were included. Children with comorbities were excluded. Quality of life was evaluated using the obstructive sleep apnea questionnaire (OSA-18), which was completed prior to, 10 days, 6 months, 12 months and, at least, 18 months after the procedure. For statistical analysis, p -values lower than 0.05 were defined as statistically significant. Results A total of 31 patients were enrolled in the study. The average age was 5.2 years, and 16 patients were male. The OSA-18 scores improved after the procedure in all domains, and this result was maintained until the last evaluation, done 22 ± 3 months after the procedure. Improvement in each domain was not superior to achieved in other domains. No correlation was found between tonsil or adenoid size and OSA-18 scores. Conclusion This is the largest prospective study that evaluated the long-term effects of the surgery on the QoL of children with SDB using the OSA-18. Our results show adenotonsillectomy has a positive impact in children's QoL.

Mometasone furoate intranasal spray is effective in reducing symptoms and adenoid size in children and adolescents with adenoid hypertrophy

IntroductionThe use of mometasone furoate (MF) intranasal spray in treating adenoid hypertrophy (AH) has a variable outcome due the different methods of adenoid size evaluation. The aim of our study was to evaluate the effect of MF intranasal spray in children and adolescents with AH using a reliable and consistent endoscopic evaluation. Material and methodA prospective interventional study was conducted. Evaluation took place during the first visit (week 0) and second visit (week 12). Symptoms of nasal obstruction, rhinorrhoea, cough and snoring were assessed, and an overall total symptoms score was obtained. A rigid nasoendoscopic examination using a four-grading system of adenoid size from 1 to 4 was performed. Patients were treated with MF intranasal spray for 12 weeks. Patients’ aged 7–11-years old used 1 spray in each nostril once daily, while patients aged 12–17 used two sprays in each nostril once daily. Reassessment was carried out during the second visit (week 12). ResultsA total of 74 patients was recruited. There were significant improvements from week 0 to week 12 in the symptoms’ score for nose obstruction, rhinorrhoea, cough, snoring including the total nasal symptoms’ score (p<0.001). AH significantly reduced in size from week 0 (2.89±.87) to week 12 (1.88±.83) (p<0.001). ConclusionMF intranasal spray is effective in improving the symptoms attributed to AH as well as reducing the adenoid size. MF intranasal spray is advocated as a treatment option before adenoidectomy is considered.
