Chronic adenotonsillitis — Clinical Guidelines

Overview

Chronic adenotonsillitis is characterized by recurrent or persistent inflammation of the tonsils and adenoids, often leading to hypertrophy and contributing to frequent upper respiratory tract infections in children 1. This condition significantly impacts quality of life and may necessitate surgical intervention if conservative management fails 1 13.

Diagnosis

Recurrent or persistent sore throat and fever 1.

Presence of enlarged tonsils and adenoids with possible obstructive symptoms 1 12.

Microbiological evidence of infection (e.g., biofilm formation by Haemophilus influenzae 10).

Elevated exhaled nitric oxide levels 4.

Changes in pulmonary function tests, such as reduced peak exploratory flow rate 12.

Imaging or clinical signs of obstructive sleep apnea or cardiopulmonary complications 15 18.

Management

First-line treatments: Antibiotics targeting common pathogens (e.g., Haemophilus influenzae, Streptococcus pneumoniae) 17.

Adjunctive therapies: Aerosol antibiotic therapy as a potential alternative to surgery 8.

Surgical intervention: Adenotonsillectomy is often indicated for refractory cases, with unilateral tonsillectomy showing effectiveness in some cases 13.

Postoperative monitoring: Assessment of arterial blood gases and acid-base balance to evaluate cardiopulmonary status 15.

Special Populations

Pediatrics: Day-case adenotonsillectomy is safe and acceptable in pediatric patients 14.

Comorbidities: Pulmonary function tests are crucial in evaluating and monitoring obstructive pulmonary disease in children with chronic adenotonsillitis 18.

Key Recommendations

Perform adenotonsillectomy for children with chronic adenotonsillitis refractory to medical management to alleviate symptoms and prevent complications (Evidence: Moderate 1 13).

Consider aerosol antibiotic therapy as a non-surgical option for children awaiting adenotonsillectomy, particularly in resource-limited settings (Evidence: Weak 8).

Evaluate pulmonary function pre- and post-adenotonsillectomy in children with chronic adenotonsillitis to monitor for transient obstructive changes (Evidence: Moderate 12 18).
