Efficacy of montelukast for adenoid hypertrophy in paediatrics: A systematic review and meta-analysis.

INTRODUCTION: Leukotrienes play a significant role in the pathogenesis of adenoid hypertrophy (A.H.). Therefore, we aimed to analyse the role of montelukast, a leukotriene receptor antagonist, alone or in combination with mometasone, a potent local intranasal steroid, for the treatment of A.H. METHODS: Participants were children with A.H. were treated with montelukast alone or montelukast and mometasone furoate. The main outcome measures were effect of montelukast on clinical symptoms of A.H. A literature review was conducted using online search engines, Cochrane Library, PubMed, Web of Science and Scopus, for randomized clinical trials assessing children with A.H. treated with montelukast alone or montelukast and mometasone furoate. Seven randomized clinical trials (RCTs) were included with 742 children. RESULTS: Our study reveals that montelukast alone or in combination with intranasal mometasone furoate significantly improves clinical symptoms of adenoid hypertrophy such as snoring, sleeping disturbance, mouth breathing and A/N ratio. Montelukast was superior to placebo in decreasing snoring (SMD = -1.00, 95% CI [-1.52, -0.49]), sleep discomfort (SMD = -1.26, 95% CI [-1.60, -0.93]), A/N ratio (MD = -0.11, 95% CI [-0.14, -0.09]) and mouth breathing (SMD = -1.36, 95% CI [-1.70, -1.02]). No difference was detected between montelukast and mometasone versus mometasone alone in snoring (SMD = -0.21, 95%CI [-0.69, 0.27]); however, the combination group was superior to the mometasone alone in mouth breathing (SMD = -0.46, 95% CI [-0.73, -0.19]). CONCLUSIONS: The limitation of studies included a small sample size, with an overall low to medium quality. Thus, further larger, higher-quality RCTs are recommended to provide more substantial evidence.

Predicting the outcome after adenoidectomy-alone for adenoid hypertrophy causing sleep disordered breathing.

PURPOSE: By using preoperative parameters age, body mass index, nasopharyngeal obstruction as assessed using flexible videonasopharyngoscopy, and quality of life scores in patients undergoing adenoidectomy-alone because of adenoid hypertrophy causing sleep disordered breathing, we aimed to examine the relationship between the change in quality of life scores, and preoperative parameters and to develop a tool to predict the change. MATERIALS AND METHODS: Patients who were scheduled for adenoidectomy-alone in a 12-month period were included. Flexible videnonasopharyngoscopy of the nasopharynx was performed. Nasopharyngeal obstruction was measured by using Image J software. Preoperative quality of life was evaluated using OSA-18 quality of life survey. OSA-18 survey has 5 subcategories consisting of sleep disturbance (O1), physical suffering (O2), emotional distress (O3), daytime problems (O4), caregiver concerns (O5). A question about the overall quality of life(O6) was added. Postoperative OSA-18 domain scores were obtained at the 3-month-follow-up. Preoperative OSA-18 subscores were compared to postoperative subscores. Linear regression analysis to predict the proportional change in OSA-18 subscores was performed. RESULTS: Our study group consisted of 94 cases. Mean postoperative O1, O2,O3, O4 and O5 scores were significantly lower compared to the preoperative scores. Mean postoperative O6 score was significantly higher. Linear regression analysis was carried out for predicting change in O1(r2 = 0.686; p = 0.006), O5(r2 = 0.711; p = 0.003) and O6(r2 = 0.757; p = 0.001). CONCLUSION: Change in quality of life scores for sleep disturbance, physical suffering and general quality of life may be predicted by using preoperative parameters.

Meta-analysis of Chinese medicine in the treatment of adenoidal hypertrophy in children.

OBJECTIVE: To evaluate the efficacy and safety of Chinese medicine in the treatment of adenoid hypertrophy in children. METHOD: Screening standard articles, extracting relevant data from meta-analysis, were analyzed by Revman5.1 software, by searching PubMed, Medline, VIP, Wan Fang and Chinese HowNet database 2006-2016 in traditional Chinese medicine treatment of children with adenoid literature. RESULTS: 206 articles met the inclusion criteria, of which ten were selected and included in the meta-analysis, and there were 803 patients. The results showed that the remission rate of the Chinese medicine treatment group was better than that of the Western medicine group. The combined effect of the amount of OR 2.06, 95% Cl (1.45, 2.96) and the combined effect of the amount of the test Z = 4.12, P < 0.00001 showed the recurrence of the disease was lower in traditional Chinese medicine treatment group than the Western medicine group. The combined effect of the amount of OR 3.05, 95% Cl (2.11, 4.56) and the combined effect of the amount of the test Z = 5.86, P < 0.00001 showed the total effective rate is high in the traditional Chinese medicine treatment group than the Western medicine group. The difference between the combined effect of the amount of OR 2.79, 95% Cl (1.78, 5.03) and the combined effect of the amount of the test of Z = 4.54, P < 0.00001 was statistically significant, which showed the treatment effect of Chinese medicine group is obviously better than the Western medicine group. CONCLUSION: The use of Chinese medicine for the treatment of children with adenoid hypertrophy has good clinical efficacy.

Adenoid hypertrophy causing obstructive sleep apnea in children after pharyngeal flap surgery.

PURPOSE: Pharyngeal flap surgery used for treatment of velopharyngeal insufficiency (VPI) may be followed by obstructive sleep apnea (OSA) especially if the patient has developed adenoid hypertrophy. However, adenoidectomy may adversely affect speech in these patients. The aim of this study was to assess the effectiveness of transnasal endoscopic power-assisted adenoidectomy in relieving OSA in patients with adenoid hypertrophy who underwent pharyngeal flap surgery, and the impact of the procedure on their speech. METHODS: Transnasal endoscopic power-assisted adenoidectomy for nine children presenting with adenoid hypertrophy was performed. The patients had previously undergone pharyngeal flap surgery for treatment of VPI. Flexible nasopharyngoscopy was used in the diagnosis of adenoid hypertrophy. Pre- and postoperative polysomnography with measurement of apnea-hypopnea index (AHI) was done. Additionally, auditory perceptual assessment of speech (APA) and nasalance scores was measured pre- and postoperatively. RESULTS: All patients were shown to have OSA by polysomnography, and a larger adenoid size was significantly associated with a higher AHI. We achieved a significant improvement in AHI after adenoidectomy. However, six patients still demonstrated OSA, albeit with a reduced severity. Speech was not adversely affected postoperatively as the APA and nasalance scores showed non-significant changes. CONCLUSION: Adenoid hypertrophy may be encountered in children who undergo pharyngeal flap surgery, which may cause OSA. Transnasal endoscopic power-assisted adenoidectomy is a safe and effective method for treatment of OSA in those patients without prejudicing the pharyngeal flap, and it has no adverse effect on speech.

[The effect of orthodontic treatment on the change of oropharynx features in patients with dentoalveolar anomalies and nasopharyngeal tonsil hypertrophy].

The paper presents the results of comprehensive survey and orthodontic treatment of 40 children with dentoalveolar anomalies and nasopharyngeal tonsil hypertrophy aged 7-9 years. The linear parameters obtained by cone beam CT and TWH in the lateral projection were analyzed. The study revealed changes, indicating that the presence of nasopharyngeal tonsil hypertrophy, leads to pathology of the dental system and estimated the efficiency of muscle training and combined use of functional devices and elastopositioner «Corrector¼ for the treatment of anomalies of dentition and the formation of physiological occlusion in the process of permanent teeth eruption.

[Effectiveness of a herbal preparation tonsilgon N for the treatment of children presenting with chronic adenoiditis].

The objective of the present study was to estimate the effectiveness of the herbal preparation tonsilgon N exhibiting the anti-inflammatory and immunostimulating properties for the treatment of the children presenting with pathology of a pharyngeal tonsil. A total of 62 children at the age varying from 3 to 11 years with chronic adenoiditis (CA) were available for the examination. The study group was comprised of 32 children, the control one included 30 patients. The study has demonstrated the improvement of daytime nasal breathing in the study group compared with the control patients by 15% on day 5, by 30% on day 7, and by 73% on day 9 after the onset of the treatment. The intensity of rhinorrhea in the children treated with the herbal preparation decreased sooner than in the control group. Nasal breathing at night improved as soon as day 5 after the onset of therapy. However, the difference between the treated and control children was statistically significant only on day 7 whereas night-time nasal breathing on day 9 improved in the study group by 1.4 times compared with the control one. It is concluded that the inclusion of therapy with tonsilgon N in the combined treatment of the children presenting with chronic adenoiditis increases its effectiveness and accelerates the process of reconvalescence. Tonsilgon N is a safe medication suitable for the prolonged application.

[The possibilities for the treatment of exudative otitis media in the children presenting with chronic adenoiditis].

The objective of the present study was to improve the effectiveness of medicamental therapy of exudative otitis media in the children with recurrent and chronic adenoiditis. It was shown that the use of fluifort (carbocysteine lysine salt) for the treatment of exudative otitis media in the children presenting with chronic adenoiditis is a more effective approach in comparison with the expectant management. It is concluded that the application of carbocysteine lysine salt in combination with the mometasone furoate nasal spray ensures the rapid elimination of the symptoms of adenoiditis and significantly accelerates the resolution of exudative otitis media compared with the monotherapeutic treatment.

[Laryngopharyngeal reflux as a possible cause of adenoiditis in adult patients].

The objective of the present study was to attract attention of practitioners to the possibility of involvement of pharyngel tonsils in the pathological process in the patients presenting with gastroesophageal reflux. Two clinical cases are reported to illustrate the possibility of development of adenoid vegetations in the adult subjects with laryngopharyngeal reflux. The use of the omeprazole test and the treatment with proton pump inhibitors produced the favourable outcome (adenoid regression) without the application of intranasl corticosteroids and the surgical intervention.

[Immunomodulators for topical application to prevent and manage chronic adenoiditis in children].

The authors report the results of a study on the efficacy of topical application of the immunomodulator IRS 19 in children presenting with chronic adenoiditis and grade I-III hypertrophy of adenoid vegetation. The use of this preparation is shown to faster and more efficaciously normalize the volume of the lymphoid tissue than irrigation of the nasopharynx with saline solutions. Moreover, the treatment of chronic adenoiditis with IRS 19 promoted normalization of biocenosis of the nasopharyngeal secretion and significantly decreased the abundance of pathogenic microflora. Specifically, the overall frequency of exacerbations and the frequency of exacerbations of adenoiditis decreased three- and two-fold respectively while the duration of the disease shortened. It is recommended that the topical immunomodulator IRS 19 should be included in the programs of planned seasonal treatment of children suffering chronic adenoiditis (to be applied at least 2-3 times annually).

Long-term outcome of concurrent coblator turbinoplasty with adenotonsillectomy in children with allergic rhinitis.

BACKGROUND: Allergic rhinitis (AR) is one of the most prevalent chronic diseases in children. Patients with AR tend to have more persistent symptoms after adenotonsillectomy (T&A). OBJECTIVES: This study was aimed to evaluate the outcome of additional concurrent coblation-assisted turbinoplasty with adenotonsillectomy (T&A + T) in patients with AR. MATERIAL AND METHODS: This study included 104 children who underwent T&A, and 67 who underwent T&A + T. All patients were diagnosed as AR and were aged < 12 years at the time of surgery. Symptoms (snoring, mouth breathing, nasal obstruction, rhinorrhea, itching, and sneezing) were evaluated preoperatively and postoperatively via a questionnaire and a telephone survey. RESULTS: None of the six symptoms investigated differed significantly between the two groups preoperatively, and all evaluated symptoms exhibited dramatic improvements after the surgery in both groups. The T&A + T group showed significantly greater difference of improvement in mouth breathing and nasal obstruction than T&A group. There were no significant difference of improvements in snoring, rhinorrhea, itching and sneezing postoperatively between two groups. In multiple regression analysis, postoperative obstructive symptoms including mouth breathing and nasal obstruction were significantly associated with concurrent turbinoplasty. CONCLUSION: Concurrent turbinoplasty should be considered especially in patients who have AR and adenotonsillar hypertrophy to improve obstructive symptoms.

Efficacy of Pidotimod use in treating allergic rhinitis in a pediatric population.

BACKGROUND: Allergic rhinitis (AR) and adenoidal hypertrophy (AH) are the most frequent causative disorders of nasal obstruction in children, leading to recurrent respiratory infections. Both nasal cavities are colonized by a stable microbial community susceptible to environmental changes and Staphylococcus aureus seems to play the major role. Furthermore, nasal microbiota holds a large number and variety of viruses with upper respiratory tract infections. This local microbiota deserves attention because its modification could induce a virtuous cross-talking with the immune system, with a better clearance of pathogens. Although AR and AH present a different etiopathogenesis, they have in common a minimal chronic inflammation surrounding nasal obstruction; hence it would be challenging to evaluate the effect of an immunomodulator on this minimal chronic inflammation with possible clinical and microbiological effects. The aim of this study is therefore to evaluate the efficacy of an immunomoldulator (Pidotimod) on nasal obstruction in children with AR and/or AH and whether its action involves a variation of nasal microbiota. METHODS: We enrolled 76 children: those with allergic rhinitis (AR) sensitized to dust mites entered the AR group, those with adenoidal hypertrophy (AH) the AH group, those with both conditions the AR/AH group and those without AR ± AH as controls (CTRL). At the first visit they performed: skin prick tests, nasal fiberoptic endoscopy, anterior rhinomanometry, nasal swabs. Children with. AR ± AH started treatment with Pidotimod. After 1 month they were re-evaluated performing the same procedures. The primary outcome was the evaluation of nasal obstruction after treatment and the secondary outcome was the improvement of symptoms and the changes in nasal microflora. RESULTS: All patients improved their mean nasal flow (mNF) in respect to the baseline. In AR children mNF reached that one of CTRL. In AH children±AR the mNF was lower in respect to CTRL and AR group. We did not find any differences among all the groups at the two different time points in nasal microflora. CONCLUSIONS: Pidotimod is able to give an improvement in nasal obstruction, especially in AR children but this effect seems to be not mediated by changes in nasal microbiota.

Using nasal steroids to treat nasal obstruction caused by adenoid hypertrophy: does it work?

OBJECTIVE: To systematically review the evidence for the usage of nasal steroids to improve symptoms of nasal airway obstruction in children with adenoidal hypertrophy. DATA SOURCES: Published studies indexed in the MEDLINE (1951 to 2008), EMBASE (1974 to 2008), and the Cochrane databases (Issue 3, 2008). REVIEW METHODS: Data from the included trials were extracted and trial quality was assessed. Meta-analysis was not applicable and data were summarized in a narrative format. Evidence from excluded studies was also discussed. RESULTS: Seven studies (six randomized controlled trials and one cohort study) met the inclusion criteria of the review, including a total of 493 patients. Six of these studies demonstrated significant efficacy of various nasal steroids (mometasone, beclomethasone, flunisolide) in improving nasal obstruction symptoms and in reducing adenoid size, as measured with symptom scores and fiber-optic nasopharyngeal endoscopy, respectively. The response appeared to be a group effect and may be maintained longer-term by continuing nasal steroids at a lower maintenance dose. The treatment was safe and well-tolerated with few minor adverse events. CONCLUSION: The available evidence suggests that nasal steroids may significantly improve nasal obstruction symptoms in children with adenoid hypertrophy. This improvement appears to be associated with a reduction of adenoid size. Evidence of long-term efficacy is limited but suggests that in many children maintenance therapy is needed if symptom-relief is to persist. Further studies are required to support the use of nasal steroids as a first-line approach in these children.

Comparison of intraoperative bleeding between microdebrider intracapsular tonsillectomy and electrocautery tonsillectomy.

OBJECTIVES: We sought to assess the quantity of intraoperative bleeding from microdebrider intracapsular tonsillectomy (IT) relative to electrocautery tonsillectomy (ET). METHODS: Intraoperative tonsil bleeding was measured prospectively for all children younger than 19 years of age who underwent primary tonsillectomy for recurrent tonsillitis or adenotonsillar hypertrophy at a tertiary care academic children's hospital. We performed IT in 57 patients (33 male, 24 female; mean age, 64.3 months) and ET in 51 patients (20 male, 31 female; mean age, 92.4 months). RESULTS: Microdebrider IT resulted in more intraoperative bleeding than ET (27.9 versus 8.7 mL, p = 0.003; and 1.2 versus 0.2 mL/kg, p <0.001). The median and maximum blood losses, respectively, were 0.6 and 9.5 mL/kg for IT and 0 and 2.0 mL/kg for ET. Blood loss for ET was not related to whether a resident versus an attending physician was the operating surgeon (p = 0.11). A linear regression model did not demonstrate greater bleeding with recurrent tonsillitis (IT, p = 0.39; ET, p = 0.89) or with increased patient age (IT, p = 0.08; ET, p = 0.62). CONCLUSIONS: Microdebrider IT produces more intraoperative bleeding than ET. The difference in blood loss is statistically but not clinically significant. Microdebrider IT causes bleeding within acceptable limits, and thus patients and physicians should not be discouraged from choosing this procedure solely on the basis of the amount of intraoperative blood loss.

Phonological development in children with obstructive sleep-disordered breathing.

Adeno-tonsillar hypertrophy with obstructive sleep disordered breathing (OSDB) is known to affect oral-motor function, behaviour, and academic performance. Adeno-tonsillectomy is the most frequently performed operation in children, with total tonsillectomy (TE) being more common than partial resection, 'tonsillotomy' (TT). In the present study 67 children, aged 50-65 months, with OSBD were randomized to TE or TT. The children's phonology was assessed pre-operatively and 6 months post-operatively. Two groups of children served as controls. Phonology was affected in 62.7% of OSBD children before surgery, compared to 34% in the control group (p < .001). Also, OSBD children had more severe phonological deficits than the controls (p < .001). Phonology improved 6 months equally after both surgeries. Despite improvement post-operatively, the gap to the controls increased. Other functional aspects, such as oral motor function, were normalized regardless of surgical method--TE or TT. The impact of OSBD should be considered as one contributing factor in phonological impairment.

[Complication and prevention of transnasal endoscopic adenoidectomy in children].

OBJECTIVE: To discuss the complication and the prevention of transnasal endoscopic adenoidectomy in children. METHODS: A total of 215 children patients with adenoid hypertrophy were treated with transnasal endoscopic adenoidectomy and were followed up for 1-6 months postoperatively. We summarized the complication and their management. RESULTS: The children had a disappearance or relief of their clinical symptoms and manifestations after endoscopic adenoidectomy. Involved complication included 10 nose bleedings, 30 nasal synechia, 1 adenoidal regrowth. CONCLUSION: Endoscopic adenoidectomy is performed under direct and clear view that allows surgeons to operate conveniently and shorten surgical time. Surgeons still have to be alert to these complications and try to avoid them.

Endoscopic assisted powered adenoidectomy versus conventional adenoidectomy - a randomised controlled trial.

OBJECTIVE: To compare endoscopic assisted powered adenoidectomy with conventional curettage adenoidectomy. METHODS: 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. RESULTS: 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. CONCLUSION: 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.

Effectiveness and safety of Chinese herbal medicine for pediatric adenoid hypertrophy: A meta-analysis.

OBJECTIVE: Chinese herbal medicine has been gradually used to treat pediatric adenoid hypertrophy. This meta-analysis were conducted to evaluate the clinical efficacy and safety of Chinese herbal medicine in the treatment of pediatric adenoid hypertrophy. METHODS: Randomized controlled trials involving Chinese herbal medicine in the treatment of pediatric adenoid hypertrophy were identified from Cochrane Central Register of Controlled Trials, PubMed, EMBASE, Chinese National Knowledge Infrastructure, Chinese Biomedical Database, Wanfang Database and VIP Information Database. The methodological quality of trials was evaluated with Cochrane Handbook criteria, and the Cochrane Collaboration's Review Manager 5.3 software was used for Meta-analysis. RESULTS: A total of 13 valid articles involving 1038 patients were included. The meta-analysis showed that: Compared with western medicine treatment, Chinese herbal medicine significantly improved clinical efficacy (RR = 1.33, 95% CI [1.24,1.43]), and significantly decreased A/N ratio (MD = -0.04,95%CI [-0.05,-0.03]). Chinese herbal medicine also prominently improved the quality of life (MD = -4.77,95%CI [-8.35,-1.20]). Meanwhile, it dramatically improved snoring (MD = -0.46,95%CI [-0.62,-0.30]); mouth breathing (MD = -0.52,95%CI [-0.66,-0.39]); nasal obstruction (MD = -0.56,95%CI [-0.68,-0.45]). CONCLUSION: Chinese herbal medicine has good clinical efficacy and safety on pediatric adenoid hypertrophy, which need to be confirmed by high quality, multiple-centre, large sample randomized controlled trials.

[Endoscopic adenoidectomy]. / Endoskopik adenoidektomi.

OBJECTIVES: This study evaluated endoscopic adenoidectomy operations performed in children for hypertrophic adenoid tissue in the nasopharynx. PATIENTS AND METHODS: A total of 125 patients (67 boys, 58 girls; mean age 4.8+/-2.4 years; range 2 to 15 years) underwent endoscopic adenoidectomy under general anesthesia for one or more of the following complaints: nasal obstruction, mouth breathing, snoring, loss of appetite, slower development than peers, and decreased hearing. Preoperatively, 48 patients were eligible for endoscopic rhinoscopy, which showed an adenoid mass causing total or almost total obstruction of the nasal passage. In the remaining patients, lateral cranial radiographs showed a mass narrowing the air passage in the nasopharynx. Postoperative controls were carried out at one and four weeks by physical examination and an inquiry into the patients' satisfaction. In addition, endoscopic rhinoscopy was performed in the fourth week in eligible patients. Final controls were carried out at the end of the second year. RESULTS: At the end four weeks, none of the patients had nasal obstruction or related complaints. Postoperative endoscopic rhinoscopy performed in 39 patients showed almost complete removal of adenoid tissues. None of the patients exhibited recurrent adenoid hypertrophy at the end of two years. CONCLUSION: Hypertrophic adenoid tissue in the nasopharynx, especially those encroaching on the nasal cavity, can be removed completely under direct endoscopic visualization. Endoscopic adenoidectomy is a more satisfactory method than conventional adenoidectomy, because it allows control of how much adenoid tissue is removed.

Coblation: improving outcomes for children following adenotonsillectomy.

Tonsillectomy and adenoidectomy, 2 of the most common childhood surgeries, are performed for a number of indications, the most common being airway obstruction caused by adenotonsillar hypertrophy. Other indications for tonsillectomy include recurrent pharyngotonsillitis, streptococcal carriage, recurrent peritonsillar abscess, halitosis, and presumed neoplasia. Although adenotonsillar surgery is a safe and effective technique for treating disease and obstruction, parents remain concerned about postoperative morbidity, for which the potential is much greater after tonsillectomy than adenoidectomy. Postoperative pain and hemorrhage are 2 unpleasant side effects that can prolong postoperative recovery. Surgeons use a variety of surgical techniques to remove the tonsils and adenoids. When compared with older techniques, such as cold steel dissection and monopolar electrocautery, a new technique named Coblation that uses lower temperatures than electrocautery to remove tonsil tissue and achieve hemostasis, has been shown to reduce pain and decrease postoperative narcotic use, leading to shorter recovery times and a quicker return to normal in children.
