Rhinomanometry evaluation of the effects of adeno tonsillar hypertrophy on the nasal airflow before and after adenotonsillectomy

ABSTRACT

Adeno tonsillar hypertrophy is a common disorder in children resulting in nasopharyngal obstruction with resultant mouth breathing and or snoring. At present upper airway obstruction due to hypertrophy of the tonsils and adenoids with consequent hypoventillation and cor pulmonale has come to be called the cardiopulmonary syndrome. This study comprised 100 children complaining of long standing nasal obstruction due to adenotonsillar hypertrophy. Adeno tonsillectomy was performed and the nasal airway resistance was measured by doing anterior rhinomanometry one week before and one month after surgery. Statistical evaluation of the results showed that the nasal airway resistance was high before the operation and decreased significantly after the operation. It was concluded that the operation of adeno tonsillectomy was very highly effective in reduction of the nasal resistance and relieving symptoms of upper airway obstruction
