Insights
Adenotonsillar hypertrophy obstructs airways in children, impairing lung function. Adenotonsillectomy significantly improves pulmonary function, as measured by peak expiratory flow rate, aiding child development.
Area of Science:
- Pediatric Otolaryngology
- Respiratory Medicine
- Pediatric Pulmonology
Background:
- Adenotonsillar hypertrophy is a primary cause of pediatric upper airway obstruction.
- This condition can lead to hypoxia by compromising pulmonary functions.
- Peak expiratory flow rate (PEFR) is a reliable indicator of lung function in children.
Purpose of the Study:
- To evaluate the improvement in pulmonary functions in children following adenotonsillectomy.
- To assess changes in peak expiratory flow rate (PEFR) before and after the surgical procedure.
Main Methods:
- A prospective, observational study involving 40 children (5-15 years) with adenotonsillar hypertrophy.
- Assessment of adenoid hypertrophy using nasal endoscopy and X-ray.
- Measurement of PEFR pre-operatively and one month post-operatively using a Mini Wright peak flow meter.
- Comparison of subjective improvement using a visual analogue score.
Main Results:
- Adenotonsillectomy resulted in a statistically significant improvement in PEFR, ranging from 16% to 25.3%.
- Patients with severe hypertrophy (Grade III tonsillar, Grade IV adenoid) showed a 25.3% PEFR improvement.
- A 98.8% subjective improvement was noted in snoring complaints post-surgery.
Conclusions:
- Adenotonsillectomy effectively improves pulmonary functions in children with adenotonsillar hypertrophy.
- Enhanced lung function post-surgery may contribute to better physical and cognitive development.
- Improved pulmonary function may reduce the risk of future cardiopulmonary issues.
Abstract:
Adenotonsillar hypertrophy is one of the commonest causes of upper airway obstruction in children. It can cause hypoxic state by impairing pulmonary functions. Peak expiratory flow rate is a basic, convenient and reliable indicator of pulmonary function in children. To study the improvement in pulmonary functions by assessing Peak expiratory flow rate, before and after adenotonsillectomy in children.
Design:
Cross sectional, prospective, observational study.
Setting:
Department of otorhinolaryngology in tertiary care centre.
Subjects:
Included 40 children aged between 5 and 15 years, who had adenotonsillar hypertrophy and underwent adenotonsillectomy.
Method:
Diagnostic nasal endoscopy and X-ray, nasopharynx, was done to assess the grade of adenoid hypertrophy endoscopically and radiologically respectively. Peak expiratory flow rate was assessed using Mini Wright peak expiratory flow meter pre-operatively and 1 month post-operatively and both the readings were compared. Subjective improvement was also compared pre-operatively and post-operatively using visual analogue score. This study included 40 patients with male to female ratio of 1.6:1, 92.5% presented with mouth breathing. 92.5% presented with grade III tonsillar hypertrophy and 70% with grade III adenoid hypertrophy endoscopically. After adenotonsillectomy, improvement in Peak expiratory flow rate ranged from 16 to 25.3% which was statistically significant. Patients with grade III tonsillar and grade IV adenoid hypertrophy showed 25.3% improvement. Subjective improvement was 98.8% in the complaint of snoring. Adenotonsillectomy significantly improves pulmonary functions. This may help to improve physical and cognitive development in children and decrease chances of getting cardiopulmonary problems in later life.

Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants.

Alveolar Surface Tension
The alveolar fluid lines the luminal surface of the alveoli and exerts a force called surface tension. This force is caused by the polar water molecules in the liquid being more strongly attracted to each...
Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla. Benzonatate operates peripherally within the respiratory tract by...
