Panel 5: Impact of otitis media on quality of life and development

Validation of the German language version of the Chronic Ear Survey and its psychometric comparison with an established German measurement instrument

BACKGROUND

With the Chronic Ear Survey (CES), a validated measurement instrument for the assessment of disease-specific health-related quality of life (HRQoL) has been available internationally since 2000. The aim of this study was to provide a validated German version of this international instrument and to compare it with the German Chronic Otitis Media Outcome Test 15 (COMOT-15).

METHODOLOGY

The CES was translated into German via a forward-backward translation process. For validation, 79 patients with COM undergoing middle ear surgery were prospectively included. HRQoL was determined preoperatively and 6 months postoperatively using the CES and the COMOT-15. Pure tone audiometry was also performed at both measurement time points. In the control examination, an additional retrospective assessment of the preoperative situation was additionally performed using the CES and the COMOT-15 to assess the response shift. The determined psychometric characteristics were internal consistency, test-retest reliability, discrimination validity, agreement validity, responsiveness, and response shift for both measurement instruments. Convergent validity of both measurement instruments was assessed using linear regression.

RESULTS

On the basis of the CES, patients with COM could be reliably distinguished from patients with healthy ears. The CES showed satisfactory reliability with high internal consistency (Cronbach α 0.65-0.85) and high retest reliability (r > 0.8). The global assessment of HRQoL impairment correlated very well with the scores of the CES (r = 0.51). In addition, it showed a high sensitivity to change (standardized response mean -0.86). Compared to the COMOT-15, it showed a lower response shift (effect size -0.17 vs. 0.44). Both measurement instruments correlated only slightly with air conduction hearing threshold (r = 0.29 and r = 0.24, respectively). The concordant validity of both measurement instruments was high (r = 0.68).

CONCLUSION

The German version of the CES shows satisfactory psychometric characteristics, so that its use can be recommended. The CES focuses on the influence of ear symptoms on HRQoL, whereas the COMOT-15 also includes functional and psychological aspects. Due to only minor response shift effects, the CES is particularly suitable for studies with multiple repeat measurements.

Recurrent otitis media and behaviour problems in middle childhood: A longitudinal cohort study

AIM

To investigate the long-term effects of early-life recurrent otitis media (OM) and subsequent behavioural problems in children at the age of 10 years.

METHODS

Data from the Raine Study, a longitudinal pregnancy cohort, were used to categorise children into those with three or more episodes of OM (rOM group) and those without a history of recurrent OM in the first 3 years of life (reference group). The parent report Strengths and Difficulties Questionnaire was used to assess child behaviour at the age of 10 years. Parental questionnaires were used to report past and present diagnoses of various mental health and developmental conditions, including attention, anxiety, depression, learning, and speech-language problems. Multiple linear and logistic models were used to analyse the data and were adjusted for a fixed set of key confounding variables.

RESULTS

The linear regression analysis revealed significant, independent associations between a history of recurrent OM and higher Strengths and Difficulties Questionnaire scores, including total, internalising, externalising, emotional, attention/hyperactivity and peer problems subscales. Logistic regression analyses revealed an independent increased likelihood for children in the rOM group to have a diagnosis of attention, anxiety, learning and speech-language problems.

CONCLUSION

Children at 10 years of age with an early history of recurrent OM are more likely to exhibit attentional and behavioural problems when compared to children without a history of recurrent OM. These findings highlight the association between early-life recurrent OM and later behavioural problems that may require professional allied health-care interventions.

A Machine Learning Approach to Screen for Otitis Media Using Digital Otoscope Images Labelled by an Expert Panel

Background: Otitis media includes several common inflammatory conditions of the middle ear that can have severe complications if left untreated. Correctly identifying otitis media can be difficult and a screening system supported by machine learning would be valuable for this prevalent disease. This study investigated the performance of a convolutional neural network in screening for otitis media using digital otoscopic images labelled by an expert panel. Methods: Five experienced otologists diagnosed 347 tympanic membrane images captured with a digital otoscope. Images with a majority expert diagnosis (n = 273) were categorized into three screening groups Normal, Pathological and Wax, and the same images were used for training and testing of the convolutional neural network. Expert panel diagnoses were compared to the convolutional neural network classification. Different approaches to the convolutional neural network were tested to identify the best performing model. Results: Overall accuracy of the convolutional neural network was above 0.9 in all except one approach. Sensitivity to finding ears with wax or pathology was above 93% in all cases and specificity was 100%. Adding more images to train the convolutional neural network had no positive impact on the results. Modifications such as normalization of datasets and image augmentation enhanced the performance in some instances. Conclusions: A machine learning approach could be used on digital otoscopic images to accurately screen for otitis media.

Effect of Angiogenesis and Lymphangiogenesis in Diesel Exhaust Particles Inhalation in Mouse Model of LPS Induced Acute Otitis Media

Lymphangiogenesis and angiogenesis might have significant involvement in the pathogenesis of otitis media with effusion. This study investigated the effect of diesel exhaust particles (DEP) on inflammation and lymphangiogenesis in a mouse model of acute otitis media (AOM). BALB/c mice were injected with LPS and exposed to 100 µg/m³ DEP. The mice were divided into four groups: control (no stimulation), AOM, AOM + DEP, and DEP + AOM.

The effects of DEP inhalation pre- and post-DEP induction were estimated based on measurements of the auditory brainstem response, mRNA levels of lymphangiogenesis-related genes and cytokines, and histology of the middle ear. Cell viability of human middle ear epithelial cells decreased in a dose-response manner at 24 and 48 hours post-DEP exposure. DEP alone did not induce AOM. AOM-induced mice with pre- or post-DEP exposure showed thickened middle ear mucosa and increased expression of TNF-α and IL1-β mRNA levels compared to the control group, but increased serum IL-1β levels were not found in the AOM + Post DEP. The mRNA expression of TLR4, VEGFA, VEGFAC, and VEGFR3 was increased by pre-AOM DEP exposure.

The expression of VEFGA protein was stronger in the AOM + Post DEP group than in any other group. The expression of CD31 and CD45 markers in the mouse middle ear tissue was higher in the Pre DEP + AOM group than in the AOM group. This result implies that pre-exposure to DEP more strongly increases inflammation and lymphangiogenesis in a mouse model of acute otitis media.

Results and Quality of Life after Implantation of Active Middle Ear Implants

The provision of implantable hearing aids represents an area with high development and innovation potential. On the one hand, this review article provides an overview of current indication criteria for the treatment with active middle ear implants. On the other hand, outcome parameters as well as functional results after implantation of active middle ear implants are demonstrated and discussed. The focus is mainly placed on audiological results as well as the subjective health status. "Patient Reported Outcome Measures" (PROMs) have become an integral part of the evaluation of hearing implant treatment. Due to low evidence level criteria, the study situation regarding audiological as well as subjective outcome parameters is not satisfactory. The lack of an international consensus on accepted outcome parameters makes a meta-analytical analysis of results immensely difficult. In the studies published to date, patients with sensorineural hearing loss and patients with conductive or mixed hearing loss offered better speech recognition after implantation of an active middle ear implant compared to conventional hearing aids. Current analyses show a significant improvement in general as well as hearing-specific quality of life after implantation of an active middle ear implant. To date, no validated, hearing-specific quality-of-life measurement instruments exist for assessing the success of fitting in children. Especially in children with complex malformations of the outer ear and the middle ear, excellent audiological results were shown. However, these results need to be substantiated by quality-of-life measurements in future.

Tympanoplasty and adenoidectomy in children: Comparison of simultaneous and sequential approaches

Background

The authors sought to compare simultaneous and sequential tympanoplasty and adenoidectomy surgery in pediatric patients.

Methods

This retrospective single-center study included 65 children (36 males, 29 females; mean age 9.16 ± 3.82 years; range 3–17 years) requiring both tympanoplasty and adenoidectomy. Simultaneous surgeries were performed on the same day, during single general anesthesia, whereas sequential surgeries were separated at least 12 weeks. The groups were compared with regard to restoration of hearing, tympanic membrane status, and utilization of medical resources. All study participants had a 12-months follow-up period after surgery.

Results

No statistically significant differences were observed between the groups regarding pre- and post-operative ABG values and average hearing gains. However, the post-operative ABG was significantly lower than the pre-operative ABG in both groups (p<0.001). There were no significant differences between simultaneous and sequential groups with respect to complete healing rates and complications (all p>0.355). Simultaneous tympanoplasty and adenoidectomy surgery management is associated with a significantly decreased cumulative hospital stay, cumulative operating room time, and cumulative pure surgical time (all p≤0.016).

Conclusions

The results of first comparative study of simultaneous versus sequential tympanoplasty and adenoidectomy surgery managements demonstrate no advantages for the sequential approach. The same-day surgery can show the clinical outcomes comparable to those in the sequential group. The simultaneous surgery approach appears to be associated with reduced medical resources consumption. Therefore, simultaneous surgery management is an effective and safe option for children with chronic otitis media and adenoid hypertrophy.

The broader impacts of otitis media and sequelae for informing economic evaluations of pneumococcal conjugate vaccines

INTRODUCTION

Otitis media (OM) is a common childhood infection. Pneumococcal conjugate vaccines (PCVs) prevent OM episodes, thereby reducing short- and long-term clinical, economic, humanistic, and societal consequences. Most economic evaluations of PCVs focus on direct health gains and cost savings from prevented acute episodes but do not fully account for the broader societal impacts of OM prevention.

AREAS COVERED

This review explores the broader burden of OM on children, caregivers, and society to better inform future economic evaluations of PCVs.

EXPERT OPINION

OM causes a substantial burden to society through long-term sequelae, productivity losses, reduced quality of life for children and caregivers, and contribution to antimicrobial resistance from inappropriate antibiotic use. The effect of PCVs on acute OM has been recognized globally, yet the broader impact has not been consistently quantified, studied, or communicated. Economic evaluations of PCVs must evolve to include broader effects for patients, caregivers, and society from OM prevention. Future PCVs with broader coverage may further reduce OM incidence and antimicrobial resistance, but optimal uptake will depend on increasing the recognition and use of novel frameworks that include broader benefits. Communicating the full value of PCVs to decision makers may result in wider access and positive societal returns.

Clinical Practice Guideline: Tympanostomy Tubes in Children (Update)

OBJECTIVE

Insertion of tympanostomy tubes is the most common ambulatory surgery performed on children in the United States. Tympanostomy tubes are most often inserted because of persistent middle ear fluid, frequent ear infections, or ear infections that persist after antibiotic therapy. All these conditions are encompassed by the term otitis media (middle ear inflammation). This guideline update provides evidence-based recommendations for patient selection and surgical indications for managing tympanostomy tubes in children. The guideline is intended for any clinician involved in managing children aged 6 months to 12 years with tympanostomy tubes or children being considered for tympanostomy tubes in any care setting as an intervention for otitis media of any type. The target audience includes specialists, primary care clinicians, and allied health professionals.

PURPOSE

The purpose of this clinical practice guideline update is to reassess and update recommendations in the prior guideline from 2013 and to provide clinicians with trustworthy, evidence-based recommendations on patient selection and surgical indications for managing tympanostomy tubes in children. In planning the content of the updated guideline, the guideline update group (GUG) affirmed and included all the original key action statements (KASs), based on external review and GUG assessment of the original recommendations. The guideline update was supplemented with new research evidence and expanded profiles that addressed quality improvement and implementation issues. The group also discussed and prioritized the need for new recommendations based on gaps in the initial guideline or new evidence that would warrant and support KASs. The GUG further sought to bring greater coherence to the guideline recommendations by displaying relationships in a new flowchart to facilitate clinical decision making. Last, knowledge gaps were identified to guide future research.

METHODS

In developing this update, the methods outlined in the American Academy of Otolaryngology-Head and Neck Surgery Foundation's "Clinical Practice Guideline Development Manual, Third Edition: A Quality-Driven Approach for Translating Evidence Into Action" were followed explicitly. The GUG was convened with representation from the disciplines of otolaryngology-head and neck surgery, otology, pediatrics, audiology, anesthesiology, family medicine, advanced practice nursing, speech-language pathology, and consumer advocacy.

ACTION STATEMENTS

The GUG made strong recommendations for the following KASs: (14) clinicians should prescribe topical antibiotic ear drops only, without oral antibiotics, for children with uncomplicated acute tympanostomy tube otorrhea; (16) the surgeon or designee should examine the ears of a child within 3 months of tympanostomy tube insertion AND should educate families regarding the need for routine, periodic follow-up to examine the ears until the tubes extrude.The GUG made recommendations for the following KASs: (1) clinicians should not perform tympanostomy tube insertion in children with a single episode of otitis media with effusion (OME) of less than 3 months' duration, from the date of onset (if known) or from the date of diagnosis (if onset is unknown); (2) clinicians should obtain a hearing evaluation if OME persists for 3 months or longer OR prior to surgery when a child becomes a candidate for tympanostomy tube insertion; (3) clinicians should offer bilateral tympanostomy tube insertion to children with bilateral OME for 3 months or longer AND documented hearing difficulties; (5) clinicians should reevaluate, at 3- to 6-month intervals, children with chronic OME who do not receive tympanostomy tubes, until the effusion is no longer present, significant hearing loss is detected, or structural abnormalities of the tympanic membrane or middle ear are suspected; (6) clinicians should not perform tympanostomy tube insertion in children with recurrent acute otitis media who do not have middle ear effusion in either ear at the time of assessment for tube candidacy; (7) clinicians should offer bilateral tympanostomy tube insertion in children with recurrent acute otitis media who have unilateral or bilateral middle ear effusion at the time of assessment for tube candidacy; (8) clinicians should determine if a child with recurrent acute otitis media or with OME of any duration is at increased risk for speech, language, or learning problems from otitis media because of baseline sensory, physical, cognitive, or behavioral factors; (10) the clinician should not place long-term tubes as initial surgery for children who meet criteria for tube insertion unless there is a specific reason based on an anticipated need for prolonged middle ear ventilation beyond that of a short-term tube; (12) in the perioperative period, clinicians should educate caregivers of children with tympanostomy tubes regarding the expected duration of tube function, recommended follow-up schedule, and detection of complications; (13) clinicians should not routinely prescribe postoperative antibiotic ear drops after tympanostomy tube placement; (15) clinicians should not encourage routine, prophylactic water precautions (use of earplugs or headbands, avoidance of swimming or water sports) for children with tympanostomy tubes.The GUG offered the following KASs as options: (4) clinicians may perform tympanostomy tube insertion in children with unilateral or bilateral OME for 3 months or longer (chronic OME) AND symptoms that are likely attributable, all or in part, to OME that include, but are not limited to, balance (vestibular) problems, poor school performance, behavioral problems, ear discomfort, or reduced quality of life; (9) clinicians may perform tympanostomy tube insertion in at-risk children with unilateral or bilateral OME that is likely to persist as reflected by a type B (flat) tympanogram or a documented effusion for 3 months or longer; (11) clinicians may perform adenoidectomy as an adjunct to tympanostomy tube insertion for children with symptoms directly related to the adenoids (adenoid infection or nasal obstruction) OR in children aged 4 years or older to potentially reduce future incidence of recurrent otitis media or the need for repeat tube insertion.

Sprachtherapeutische Versorgung 4-jähriger Kinder in Hessen: ein Überblick

Hintergrund

Eine verspätete Erkennung bzw. versäumte Intervention bei Sprachentwicklungsstörungen beeinträchtigen den schulischen und beruflichen Werdegang. Aufgrund ungünstiger soziodemografischer Bedingungen (mangelhafte Deutschkenntnisse der Eltern, niedriges familiäres Einkommen etc.) sowie medizinischer Auffälligkeiten sind zunehmend viele Kinder in ihrer Sprachentwicklung gefährdet.

Ziel der Arbeit

Im Rahmen einer hessischen Sprachstanderfassungsstudie wurde geprüft, inwiefern 4‑jährige Kinder mit (KMM) und ohne Migrationshintergrund (KOM) sprachtherapeutisch versorgt wurden, und wie diese Therapien motiviert waren.

Material und Methoden

Vierjährige Kindergartenkinder (n = 1384) wurden mit dem Sprachtest KiSS.2 untersucht. Beide Untergruppen (KMM und KOM) wurden hinsichtlich sprachbezogener Störungsbilder und sprachtherapeutischer Versorgung verglichen.

Ergebnisse

Insgesamt nahmen 8 % aller Kinder an Sprachtherapien teil. KMM waren fast doppelt so häufig klinisch abklärungsbedürftig wie KOM (21 % vs. 11 %). Bei KOM wurden dagegen mehr sprachbezogene Störungsbilder (z. B. häufige Mittelohrentzündungen) bereits vor der Studienteilnahme diagnostiziert. Klinisch abklärungsbedürftige KOM befanden sich daher häufiger in einer Sprachtherapie als KMM (37 % vs. 23 %).

Diskussion

Es fanden sich Hinweise für Diskrepanzen zwischen Sprachtherapiebedarf und sprachtherapeutischer Versorgung von bestimmten Untergruppen der 4‑jährigen Kinder. Evidenzbasierte, flächendeckende Sprachstanderfassungsprogramme können dazu beitragen, dass bei der Einteilung der Kinder in sprachförder- und sprachtherapiebedürftige weniger falsch-positive bzw. -negative Ergebnisse erzielt werden.

Impact of COVID-19 pandemic on the incidence of otitis media with effusion in adults and children: a multicenter study

Purpose

To compare and analyze the incidence of otitis media with effusion (OME), before and during the COVID-19-related pandemic period, to evaluate the effects of the social changes (lockdown, continuous use of facial masks, social distancing, reduction of social activities) in the OME incidence in children and adults.

Methods

The number of diagnosed OME in e five referral centers, between 1 March 2018 and 1 March 2021, has been reviewed and collected. To estimate the reduction of OME incidence in children and adults during the COVID-19 pandemic period the OME incidence in three period of time were evaluated and compared: group 1—patients with OME diagnosis achieved between 1/03/2018 and 01/03/2019 (not pandemic period). Group 2—patients with OME diagnosis achieved between 1/03/2019 and 1/03/2020 (not pandemic period). Group 3—patients with OME diagnosis achieved between 1/03/2020 and 1/03/2021 (COVID-19 pandemic period).

Results

In the non-pandemic periods (group 1 and 2), the incidence of OME in the five referral centers considered was similar, with 482 and 555 diagnosed cases, respectively. In contrast, the OME incidence in the same centers, during the pandemic period (group 3) was clearly reduced with a lower total number of 177 cases of OME estimated. Percentage variation in OME incidence between the first non-pandemic year considered (group 1) and the pandemic period (group 3) was—63, 3%, with an absolute value decrease value of—305 cases. Similarly, comparing the second non-pandemic year (group 2) and the pandemic year (group 3) the percentage variation of OME incidence was—68, 1% with an absolute value of—305 cases decreased.

Conclusions

Our findings showed a lower incidence of OME during the pandemic period compared with 2 previous non pandemic years. The drastic restrictive anti-contagion measures taken by the Italian government to contain the spread of COVID-19 could have had a positive impact on the lower OME incidence during the last pandemic year.

Continuous Microevolution Accelerates Disease Progression during Sequential Episodes of Infection

Bacteria adapt to dynamic changes in the host during chronic and recurrent infections. Bacterial microevolution is one type of adaptation that imparts a selective advantage. We hypothesize that recurrent episodes of disease promote microevolution through genetic mutations that modulate disease severity. We use a pre-clinical model of otitis media (OM) to determine the potential role for microevolution of nontypeable Haemophilus influenzae (NTHI) during sequential episodes of disease. Whole genome sequencing reveals microevolution of hemoglobin binding and lipooligosaccharide (LOS) biosynthesis genes, suggesting that adaptation of these systems is critical for infection. These OM-adapted strains promote increased biofilm formation, inflammation, stromal fibrosis, and an increased propensity to form intracellular bacterial communities (IBCs). Remarkably, IBCs remain for at least one month following clinical resolution of infection, suggesting an intracellular reservoir as a nidus for recurrent OM. Additional approaches for therapeutic design tailored to combat this burdensome disease will arise from these studies.

Harrison et al. develop a sequential model of otitis media (OM) to investigate microevolution through genetic mutations that modulate disease severity. OM-adapted strains promote increased biofilm, inflammation, stromal fibrosis, and intracellular bacterial community (IBC) development. IBCs remain one month following clinical resolution of infection, suggesting a nidus for recurrent OM.

Effectiveness of the 7- and 13-Valent Pneumococcal Conjugate Vaccines Against Vaccine-Serotype Otitis Media

Background

Despite the demonstrated impact of pneumococcal vaccine (PCV) implementation on otitis media (OM), demonstration of real-life serotype-specific effectiveness of the 7-valent and 13-valent PCVs (PCV7 and PCV13) is lacking owing to the paucity of culture-positive cases. Furthermore, prelicensure PCV13 efficacy against OM was not studied.

Methods

The study was conducted from October 2009 to July 2013. Case patients were children aged 5–35 months with OM (mostly complex OM [recurrent/nonresponsive, spontaneously draining, chronic with effusion]) from whom middle-ear fluid culture was obtained; controls were contemporary children with rotavirus-negative gastroenteritis in a prospective population-based rotavirus surveillance, from the same age group with similar ethnic distribution and geographic location. Vaccine effectiveness (VE) was estimated as 1 minus the odds ratio using unconditional logistic regression, adjusting for time since PCV implementation, age, and ethnicity.

Results

A total of 223 case patients and 1370 controls were studied. Serotypes 19F and 19A together caused 56.1% of all vaccine-type (VT) OM. VE of ≥2 PCV doses in children aged 5–35 months was demonstrated as follows: PCV7 against OM due to PCV7 serotypes, 57.2% (95% confidence interval, 6.0%–80.5%); PCV13 against OM due to PCV13 serotypes, 77.4% (53.3%–92.1%); PCV13 against OM due to the 6 additional non-PCV7 serotypes 67.4% (17.6%–87.1%); PCV13 against OM due to serotype 19F, 91.3% (1.4%–99.2%); and PCV13 against OM due to serotype 3, 85.2% (23.9%–98.4%). PCV7 and PCV13 VE against OM due to serotype 19A in children aged 12–35 months was 72.4% (95% confidence interval, 6.2%–91.9%) and 94.6% (33.9%–99.6%), respectively.

Conclusions

PCV7 and PCV13 were effective against complex OM caused by the targeted serotypes.

Targeting host-microbial interactions to develop otitis media therapies

Otitis media (OM; middle ear infection) is the most common reason for pre-school children to visit a doctor, be prescribed antimicrobials, or undergo surgery. Recent Cochrane reviews of clinical trials have identified that antibiotics and grommet surgery are only moderately effective in treating OM, with recurrent or persistent infection observed in one-third of children. Research efforts are focusing on developing improved therapies to treat OM and prevent disease recurrence. The recurrent nature of OM is mostly due to the persistence of bacterial pathogens within established biofilm in the middle ear. Promising novel therapies are harnessing host-microbe interactions to disrupt middle ear biofilm and permit antibiotics to work more effectively. New approaches are also being developed to prevent OM, including new vaccines and mining the host respiratory microbiome to develop novel bacterial therapies. This review describes how our improved knowledge of human and microbial interactions is driving development of OM therapies to improve health outcomes for children in Australia and worldwide.

Impact of depressive disorders on quality of life after middle ear surgery in patients with chronic otitis media

Purpose

The aim of this study was to determine whether preoperative depressive symptoms influence health-related quality of life (HRQOL) after middle ear surgery in patients with chronic otitis media (COM).

Methods

This prospective clinical case study was conducted at a tertiary referral center. All 102 patients who had undergone middle ear surgery for COM were assessed clinically and by audiometric testing (pure tone audiometry) in pre- and postoperative settings. Disease-specific HRQOL was assessed by the validated chronic otitis media outcome test 15 (COMOT-15) and the Zurich chronic middle ear inventory (ZCMEI-21). General HRQOL was measured using the short form 36 (SF-36). Depressive symptoms were assessed using the patient health questionnaire (PHQ-D). The Charlson comorbidity index (CCI) was used to classify comorbidities. The middle ear status was determined using the ossiculoplasty outcome parameter staging (OOPS) index.

Results

After middle ear surgery, the total COMOT-15 and ZCMEI-21 scores improved significantly (p < 0.001). General HRQOL (total SF-36 score) was unaffected by surgery (p < 0.05). Patients without elevated depressive symptoms had significantly better total scores for the COMOT-15 (p < 0.01), ZCMEI-21 (p < 0.001), and for SF-36 (p < 0.001) postoperatively. The results of the multiple regression analyses show that, after adjusting for the OOPS, CCI, and hearing improvement, preoperative depressiveness was significantly associated with worse postoperative COMOT-15 and ZCMEI-21 outcome scores (β = 0.425 and β = 0.362, p < 0.001).

Conclusion

Preoperative depressiveness was an essential predictive factor for HRQOL in patients with COM. This should be considered during patient selection to provide more suitable preoperative counseling.

[Diagnostics and treatment of adenotonsillar hyperplasia in children]

Adenoidectomy, paracentesis, and tonsillar interventions are the most common operations in childhood. Hypertrophy of the lymphatic tissue of Waldeyer's ring can lead to individually distinct, acute, and chronic symptoms as well as anatomical and functional changes. When presented with affected children in otolaryngologic practice, the combination of parental interview, questionnaire-based screening for obstructive sleep apnea syndrome, and physical examination including ear microscopy, inspection of the oropharynx and, if necessary, the nasopharynx, has proven its worth. Audiometric diagnosis for detection of tympanic effusion should be mandatory. The treatment of choice is adenoidectomy, if necessary plus tonsillotomy and paracentesis with a tympanic tube insert. However, the indication remains controversial, as the effectiveness of the interventions seems to depend on the preoperative severity of symptoms. With a correct indication, effective symptom reduction, improvement in quality of life, and high parent satisfaction can be expected.
