Adenoid hypertrophy is a common childhood condition with unclear etiology and potentially severe consequences. The disease consists of increased adenoid tonsils and represents one of the most frequent surgical indications in this age period.
Presentation
The disease affects males and females to the same extent and is rarely encountered after the age of 15 years because adenoid tissue undergoes a normal process of involution beyond this age [1] [2]. Patients usually present between the ages of 3 and 5 because adenoid growth causes nasopharyngeal airway narrowing [3]. Children from high socioeconomic classes are infrequently affected.
In incipient stages, adenoid hypertrophy is asymptomatic. As the disease progresses, patients manifest with chronic mouth breathing, sleep disturbances, nasal obstruction, rhinorrhea, swallowing difficulties, snoring, cough, epistaxis, and halitosis. Hearing loss develops gradually as a consequence of persistent or recurring middle ear infections. If left untreated for a long period of time, the patient presents with hyponasal voice and a typical facies, characterized by elongated middle facial area and narrow palate [4].
When obstructive sleep apnea develops as a consequence of adenoid hypertrophy, it can cause more severe, long-term morbidity such as failure to thrive, learning difficulties, delayed speech [5], decreased intelligence quotient, and hyperactivity. Possible cardiovascular impairment consists of elevated diastolic blood pressure, left ventricular hypertrophy, and decreased right ventricular ejection fraction [1] [6].
Clinical examination may reveal signs consistent with atopy such as a cough, expiratory wheezing and rhonchi, and prolonged expiratory time.

Recurrent Otitis Media
Chronic adenoid infection could lead to the obstruction of the nasopharyngeal Eustachian tube orifice and consequent recurrent otitis media. Therefore, a complete examination of an ear, nose, and throat is useful in all patients. [symptoma.com]
An adenotonsillectomy is indicated in patients with chronic/recurrent sinusitis, chronic/recurrent otitis media, and/or symptomatic nasal obstruction. Epidemiology Adenoid hypertrophy is the most common cause of nasal obstruction in children. [amboss.com]

Numerous studies have shown that adenoidectomy is more effective than conservative treatment in patients with recurrent otitis media, especially exudative otitis media. [czytelniamedyczna.pl]

Tonsillar Hypertrophy
There was also a significant difference between rates of tonsillar hypertrophy and nasopharynx obstruction in the EN group (p 0.009). [pagepressjournals.org]
Due to the multifactorial etiology of the tonsillar hypertrophy, the patient’s comorbidities must also be taken into account. [czytelniamedyczna.pl]
For most of them there is a vicious cycle established, where the adenoid-tonsillar hypertrophy constitutes the main item for the rest of the visceral-cranial alterations and the teeth occlusion. [medigraphic.com]
There might also be a genetic link, as tonsillar hypertrophy often runs in families. [healthline.com]

Halitosis
As the disease progresses, patients manifest with chronic mouth breathing, sleep disturbances, nasal obstruction, rhinorrhea, swallowing difficulties, snoring, cough, epistaxis, and halitosis. [symptoma.com]
The adenoids are located at the back of nose and when enlarged, may cause nasal obstruction, recurrent sinusitis, post nasal drip, sleep apnea, chronic runny nose, halitosis and even chronic cough. [childrensnational.org]
Halitosis (bad breath) can occur because of infections of the tonsils. Snoring because of obstruction to the airway from the enlarged tonsils. [entcenterutah.com]
Workup
Adenoid hypertrophy is best diagnosed by means of flexible nasopharyngoscopy. This investigation is indicated when the manifestations presented above are present or when the patient presents with recurrent sinusitis, otitis media, or persistent ear effusions. When obstructive sleep apnea is suspected, a sleep study is called for in order to gather information about its severity. Radiological evaluation, such as the lateral neck X-ray should be avoided unless more severe pathology, such as neoplasia or angiofibroma, is suspected. However, if a radiography is performed, due to the fact that it is still considered a valid and reliable test [7] [8], the physician should assess not the absolute dimensions of the adenoids, but the degree of obstruction they cause. If adenoids are very small or absent, an immune deficiency should be investigated, while severely enlarged masses may suggest lymphatic malignancy.
Adenoid flora occasionally needs to be assessed. It is usually composed of group A beta-hemolytic streptococci, but Staphylococcus aureus, Streptococcus pneumoniae, and Haemophilus influenzae may also be encountered. Anaerobic bacteria may be found in the core of the adenoids [9]. Other possibly present bacteria include Enterococcus species, Staphylococcus epidermidis, Streptococcus viridans, Escherichia coli, Pseudomonas, Moraxella, Klebsiella, Neisseria, Prevotella, Fusobacterium, Peptostreptococcus, and Bacteroides species [10] [11]. Chronic adenoid infection could lead to the obstruction of the nasopharyngeal Eustachian tube orifice and consequent recurrent otitis media. Therefore, a complete examination of an ear, nose, and throat is useful in all patients.
Biopsy specimens reveal reactive hyperplasia of B-cells and inflammatory infiltrates consisting of polymorphonuclears, plasmocytes, or eosinophils [2] [12].
