A study of the role of different forms of chronic rhinitis in the development of otitis media with effusion in children affected by adenoid hypertrophy

Otitis media with effusion in preschool children with adenoid hypertrophy: Risk factors and nursing care

AIM

To evaluate the influencing factors of otitis media with effusion (OME) in children with adenoid hypertrophy and to provide evidence for clinical treatment and care of children with adenoid hypertrophy.

DESIGN

A retrospective study.

METHODS

Preschool children with adenoid hypertrophy treated in our hospital from 1 January 2021 to 30 July 2022 were included. We analysed the characteristics of OME and non-OME children with adenoid hypertrophy. Pearson correlation analysis and logistic regression analysis were performed to evaluate the risk factors for OME in children with adenoid hypertrophy.

CONCLUSION

A total of 166 children with adenoid hypertrophy were included; the incidence of OME in children with adenoid hypertrophy was 34.94%. The incidence of OME decreased significantly with the increase in age (p = 0.014). Logistic regression analysis showed that age < 3 years (OR = 3.149, 95%CI: 2.812-3.807) and duration of adenoid hypertrophy ≥12 months (OR = 2.326, 95%CI: 2.066-2.612) were the risk factors of OME in children with adenoid hypertrophy (all p < 0.05).

PATIENT CONTRIBUTION

The incidence of adenoid hypertrophy with OME is high in preschool children, and it is related to the age and duration of adenoid hypertrophy.

Allergy in pathogenesis of Eustachian Tube Dysfunction

Eustachian tube dysfunction (ETD) is a condition where the Eustachian tube (ET) fails to function normally, resulting in symptoms such as aural fullness, tinnitus, autophony, and hearing loss. ETD can further lead to middle ear diseases such as otitis media effusion and adhesive otitis media, which is becoming more common in the field of otology. Although the pathogenesis of ETD remains unclear, recent animal studies and clinical experiments have found allergic reactions and allergic diseases are closely related to the occurrence of ETD. As the mucosa of the ET is continuous with that of the nasopharynx and tympanic cavity, it is reasonable to assume that the immunological basis of the ET itself is similar to that of respiratory allergic diseases. However, due to the special anatomical location and complex pathogenesis of the ET, there is still no unified diagnostic gold standard. Additionally, there is an ongoing debate regarding whether ETD can be classified as a distinct disease or even an allergic disease. Furthermore, the effectiveness of anti-allergic therapy in patients with ETD is yet to be fully understood. Therefore, this review elaborates on the possible mechanisms of allergic reactions in the occurrence and development of ETD, and explores the potential role of anti-allergic therapy in managing this condition, in order to provide new insights into the pathogenesis and prevention of ETD.

150th Anniversary of global adenoid investigations: unanswered questions and unsolved problems

Although the problem of adenoid hypertrophy (AH) has been diagnosed and treated by doctors and scientists from around the world for the last 150 years, there is still no consensus regarding appropriate diagnosis, conservative treatment options, and qualification for surgery. This manuscript presents current knowledge on these issues and compares diagnostic methods and the effectiveness of treatment options. Factors that may influence the obtained treatment results are also described, and a questionnaire is proposed to compare the results of treatment. The objective of drawing attention to this problem is to obtain better results from conservative treatment in the future and better-qualified patients for surgical treatment.

Otitis media in children: Which phenotypes are most linked to allergy? A systematic review

BACKGROUND

Allergic rhinitis is a common childhood disease responsible for a major impact on quality of life and healthcare resources. Many hypotheses have been proposed to explain the link between allergy and otitis media, although a definitive mechanism has not been identified yet. One of the major critical points is that authors failed in distinguishing among different phenotypes of middle ear inflammation. This review pointed out literature evidence from the laboratory and clinical experience linking allergy to different phenotypes of otitis media in children.

METHODS

We performed a systematic review in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) process. Our search yielded 3010 articles that were finally screened. This resulted in 20 manuscripts of which the full texts were included in a qualitative analysis. We paid particular attention in distinguishing among phenotypes of otitis media.

RESULTS

Clinical evidence and analyses of biomarkers suggested that allergy may be linked to some phenotypes of otitis media and, in particular, to otitis media with effusion (OME) and acute re-exacerbations in children with middle ear effusion. It was not possible to perform the analysis for allergy and acute and chronic otitis media because of paucity and heterogeneity of data.

CONCLUSION

Allergy should be considered in the diagnostic workup of children with OME as well as OME should be excluded in children with persistent moderate to severe AR. In these cases, clinicians should evaluate prompt and accurate treatment of allergy in improving outcomes, although futures studies are required to increase evidence supporting that anti-allergy treatment may be effective in the recovery and outcome of otitis media with effusion.

Role of Allergy in Eustachian Tube Dysfunction

PURPOSE OF REVIEW

Eustachian tube dysfunction (ETD) presents with symptoms of aural fullness and pressure, muffled hearing, tinnitus, and otalgia. When severe, it can lead to many common ear disorders such as otitis media with effusion, tympanic membrane retraction/perforation, and cholesteatoma. These diseases are prevalent in both the pediatric and adult population and significantly impact quality of life. The pathophysiology of ETD in the absence of an obstructive lesion has long been debated but is thought to be related to functional obstruction (i.e., inefficient tensor veli palatini muscle) and/or nasal cavity and nasopharyngeal inflammation. In the acute setting, the most common cause of nasal inflammation is an upper respiratory infection. When symptoms become chronic, however, the inflammation is thought to be associated with nasal irritants such as nasal allergens, i.e., allergic rhinitis (AR). The purpose of this review is to summarize our current understanding of the relationship between allergy and ETD.

RECENT FINDINGS

Past studies are either lacking or have reported equivocal findings regarding the relationship between allergy and ETD, and the 2018 International Consensus Statement on Allergy and Rhinology: Allergic Rhinitis has deemed the current level of evidence linking AR and ETD as low quality. A more recent study using a large adult population dataset did support an association between AR and ETD, but did not find that all cases of ETD are related to allergies. Furthermore, current evidence suggests that the use of medications that can decrease intranasal inflammation, such as intranasal corticosteroids or oral antihistamines, does not result in significant symptomatic improvement in patients with ETD. However, these studies included all patients with ETD, and evidence is lacking regarding the treatment effect of these medications on the subset of patients with concurrent AR and ETD. Current best evidence does support an association between AR and ETD; however, not all patients with ETD suffer from AR, and vice versa. Further research is necessary to understand the mechanism behind this positive association and to elucidate the cause of chronic ETD in patients without associated allergies.

The Proposed Usage of Intranasal Steroids and Antihistamines for Otitis Media with Effusion

PURPOSE OF REVIEW

To examine the role of allergy medications in the treatment of otitis media with effusion (OME), focusing on use of intranasal steroids and antihistamines.

RECENT FINDINGS

There has been ongoing controversy regarding the role of allergy in the development of OME. Treatment of OME with medications commonly used for allergic symptomatology has been studied. Proposed treatment options include decongestants, mucolytics, oral steroids, topical steroids, antihistamines, and antibiotics. We begin by evaluating the proposed association between allergy and OME, and then evaluate intranasal steroids and oral antihistamine therapy in the treatment of OME. The role of the adenoid and concurrent nasal symptomatology is also addressed. The preponderance of data suggests that neither intranasal steroids nor antihistamines improve the long-term clearance of isolated OME and are therefore not recommended. However, data are notably limited with regard to improvement rates in OME in patients specifically with concurrent allergy and/or adenoid hypertrophy. Future studies of medications for OME would ideally incorporate study designs controlling for both allergic rhinitis and adenoid hypertrophy, to better understand the impact of these medications on OME in these subgroups of patients.

Otitis media with effusion in children: Pathophysiology, diagnosis, and treatment. A review

Otitis media with effusion (OME) is a frequent paediatric disorder. The condition is often asymptomatic, and so can easily be missed. However, OME can lead to hearing loss that impairs the child's language and behavioural development. The diagnosis is essentially clinical, and is based on otoscopy and (in some cases) tympanometry. Nasal endoscopy is only indicated in cases of unilateral OME or when obstructive adenoid hypertrophy is suspected. Otitis media with effusion is defined as the observation of middle-ear effusion at consultations three months apart. Hearing must be evaluated (using an age-appropriate audiometry technique) before and after treatment, so as not to miss another underlying cause of deafness (e.g. perception deafness). Craniofacial dysmorphism, respiratory allergy and gastro-oesophageal reflux all favour the development of OME. Although a certain number of medications (antibiotics, corticoids, antihistamines, mucokinetic agents, and nasal decongestants) can be used to treat OME, they are not reliably effective and rarely provide long-term relief. The benchmark treatment for OME is placement of tympanostomy tubes (TTs) and (in some cases) adjunct adenoidectomy. The TTs rapidly normalize hearing and effectively prevent the development of cholesteatoma in the middle ear. In contrast, TTs do not prevent progression towards tympanic atrophy or a retraction pocket. Adenoidectomy enhances the effectiveness of TTs. In children with adenoid hypertrophy, adenoidectomy is indicated before the age of 4 but can be performed later when OME is identified by nasal endoscopy. Children must be followed up until OME has disappeared completely, so that any complications are not missed.

The Influence of Age on the Relationship Between Allergic Rhinitis and Otitis Media

PURPOSE OF REVIEW

To examine the relationship between otitis media, allergic rhinitis, and age.

RECENT FINDINGS

Otitis media and allergic rhinitis are prevalent conditions with a controversial relationship. Some data suggest that these entities are significantly associated, either through allergic rhinitis inducing Eustachian tube dysfunction or through allergic pathophysiology simultaneously occurring intranasally and in the ear. Other studies, however, have refuted this relationship. For example, treatment with antihistamines does not reliably improve OME, making causation and association challenging to establish. Age may have an effect on the nature of the relationship between allergic rhinitis and otitis media, by impacting both the individual conditions and their association. Epidemiological, immunological, and adenoidal studies have suggested that differences occur with age, and this review encapsulates the related data and publications. We begin by evaluating how allergic rhinitis and otitis media each are affected by age, then evaluate the role that age may have in the relationship between the two conditions. Adult and pediatric literature are evaluated so as to include the full impact of age across patients' lifespan. Age induces changes in immunity, patterns of inflammation, and susceptibility to both allergic rhinitis and otitis media with effusion. Age may also be an effect modifier which impacts the nature of the relationship between these two conditions. The influence of age on the association between these highly prevalent conditions remains a topic of active study.

Superficial punctate keratopathy in a pediatric patient was related to adenoid hypertrophy and obstructive sleep apnea syndrome: a case report

BACKGROUND

Known causes of superficial punctuate keratopathy (SPK) in children include entropion, viral infection, blepharokeratoconjunctivitis (BKC), and toxicity of eye drops. However, there are some SPK patients whose causes could not be identified well. Herein, we describe the history, diagnosis, treatment, and prognosis of a rare case.

CASE PRESENTATION

To report a case of superficial punctate keratopathy (SPK) which coexisted with floppy eyelid syndrome (FES) and presented as intermittent red eye and blurred vision in an 11-year-old boy who slept in the prone position. His condition did not improve despite treatment with topical antibiotics (levofloxacin, tobramycin), steroid eye drops (prednisolone), and artificial tears. The patient was diagnosed with tonsil hypertrophy and nasopharyngeal adenoid hypertrophy and obstructive sleep apnea syndrome (OSAS). He underwent tonsillectomy and adenoidectomy. Then he started sleeping in the supine position postoperatively. The SPK, red eye and blurred vision completely resolved after surgery without additional treatment. The corneal sensation also recovered gradually during the next 7 years. However, the floppy eyelid did not resolve.

CONCLUSION

Recurrent SPK of childhood might be related to tonsil hypertrophy, adenoid hypertrophy and OSAS, which can be rehabilitated by a surgical approach.

International consensus (ICON) on management of otitis media with effusion in children

Otitis media with effusion (OME) is a common childhood disease defined as the presence of liquid in the middle ear without signs or symptoms of acute ear infection. Children can be impacted mainly with hearing impairment and/or co-occurring recurrent acute otitis media (AOM) thus requiring treatment. Although many meta-analyses and national guidelines have been issued, management remains difficult to standardize, and use of surgical and medical treatments continue to vary. We convened an international consensus conference as part of the 2017 International Federation of Oto-rhino-laryngological Societies Congress, to identify best practices in OME management. Overall, regional differences were minor and consensual management was obtained on several important issues. At initial assessment, although a thorough medical examination is necessary to seek reflux, allergy or nasal obstruction symptoms; an age-appropriate auditory test is the only assessment required in children without abnormal history. Non-surgical treatments poorly address the underlying problem of an age-dependent dysfunctional Eustachian tube; auto-inflation seems to be the only beneficial, low-risk and low-cost non-surgical therapy. There was a clear international recommendation against using steroids, antibiotics, decongestants or antihistamines to treat OME, because of side-effects, cost issues and no convincing evidence of long-term effectiveness. Decisions to insert tympanostomy ventilation tubes should be based on an auditory test but also take into account the child's context and overall hearing difficulties. Tubes significantly improve hearing and reduce the number of recurrent AOM with effusion while in place. Adjuvant adenoidectomy should be considered in children over four years of age, and in those with significant nasal obstruction or infection.

Panel 1: Epidemiology and Diagnosis

Objective

To create a literature review between 2011 and June 1, 2015, on advances in otitis media (OM) epidemiology and diagnosis (including relevant audiology studies).

Data Sources

Electronic search engines (PubMed, EMBASE, and Cochrane Library) with a predefined search strategy.

Review Methods

Articles with appropriate epidemiologic methodology for OM, including acute mastoiditis and eustachian tube dysfunction. Items included OM worldwide and in high-risk populations, OM-related hearing loss, news in OM diagnostics, prenatal risk factors and comorbidities, postnatal risk factors, genetics, microbiological epidemiology, guidelines, and quality of life.

Conclusions

Diagnostic evidence and genetic studies are increasing; guidelines are introduced worldwide; and there is evidence of benefit of pneumococcal conjugate vaccines. New risk factors and comordities are identified in the study period, and quality of life is affected in children and their families.

Implications for Practice

Chronic suppurative OM occurs worldwide and contributes to lifelong hearing loss. Uniform definitions are still lacking and should be provided. An association between HIV and chronic suppurative OM has been found. Tympanometry is recommended for diagnosis, with or without pneumatic otoscopy. Video otoscopy, algorithms, and validated questionnaires may assist clinicians. Childhood obesity is associated with OM. Heritability accounts for 20% to 50% of OM diagnoses. OM-prone children seem to produce weaker immunologic responses to pneumococcal conjugate vaccines. Clinicians tend to individualize treatment without adhering to guidelines.

An objective assessment of halitosis in children with adenoid vegetation during pre- and post-operative period

OBJECTIVES

Although most specialists in otorhinolaryngology and pediatrics find halitosis to be a common problem in children with adenoid hypertrophy, there are no objective data on this topic in the literature. Whether adenoid hypertrophy is a risk factor for halitosis or whether halitosis is a sign of adenoid hypertrophy remains unclear. Thus, the aim of this study was to investigate whether children diagnosed with adenoid hypertrophy have a higher probability of halitosis than do children in the normal population and whether adenoidectomy can decrease oral malodor.

METHODS

Forty children with adenoid hypertrophy and 40 healthy subjects aged 5-15 years were included in the study. The children with adenoid hypertrophy underwent adenoidectomy operations and were followed for 3 months. We measured volatile sulfur compounds (VSCs), hydrogen sulfide (H2S), methyl mercaptan (CH3SH), and dimethyl sulfide (CH3)2S using an objective method, a portable gas chromatograph (OralChroma; AbiMedical, Osaka, Japan).

RESULTS

The mean CH3SH and (CH3)2S levels were significantly different (p < 0.05) between the adenoid hypertrophy group and the controls. The H2S, CH3SH, and (CH3)2S levels in the third postoperative month were significantly lower (p < 0.05) than those in the preoperative period, and there was no significant difference postoperatively between the patients with adenoid hypertrophy and controls. There was a positive correlation between age and VSC levels, and CH3SH levels were significantly higher in patients with ventilation tube insertion, rather than just adenoidectomy.

CONCLUSIONS

There was a statistically significant association between halitosis and adenoid hypertrophy, and a significant improvement in halitosis was obtained following adenoidectomy. The present study provides an association between halitosis and adenoid hypertrophy. If there is no other oral pathology causing halitosis, halitosis can be a sign of adenoid hypertrophy in children.

Nasal Mucociliary Clearance in Adenoid Hypertrophy and Otitis Media with Effusion

Mucociliary clearance (MCC), which exists in many systems, is the first defensive mechanism of the human body. Nasal MCC has an important role in transporting the secretions of the nasal cavity and paranasal sinuses along with the trapped inhaled pathogens to the nasopharynx. Physiologic or pathologic situations that effect nasal MCC, such as temperature, humidity, nasal obstruction, allergic rhinitis, chronic infections, etc., lead to impaired MCC and related local or circumjacent system disorders. With this perspective, when a unified airway with a multiple disease principle is considered, investigating the relationship between adenoid hypertrophy (AH), otitis media with effusion (OME) and nasal MCC is logical. In this review, histological and physiologic properties of nasal MCC and its possible role involving pathologic situations such as AH and OME is discussed together with recent literature findings.

Does the type of rhinitis influence development of otitis media with effusion in children?

Otitis media with effusion (OME) is characterized by the presence of fluid in the middle ear cavity behind an intact eardrum and is considered a multifactorial condition with Eustachian tube dysfunction as the underlying pathophysiologic condition. One of the most debated causes of OME is allergy, in particular allergic rhinitis. The aim of this paper is to review the role of rhinitis in the development of OME and in particular the role of both allergic (AR) and non-allergic rhinitis (NAR). Most of the recent literature confirms the role of AR in the development of OME, while there are few reports on the role of NAR. In non-allergic children affected by obstructive adenoid hypertrophy, the presence of mast cells in the nasal smear was associated with a high risk of developing a chronic OME.
