The items that need to be examined for adenoid hypertrophy mainly include blood routine, X-ray examination, rhinoscopy, sleep apnea monitoring and so on. 1. Routine blood test: The routine blood test can be used to clarify whether the patient is infected or not, as well as anemia and other conditions. 2. X-ray examination: X-ray examination can be used to clarify the degree of thickening of the soft tissues in the nasopharynx and to exclude congenital malformations of the skull base, tumors and other diseases. 3. Rhinoscopy: including anterior rhinoscopy and indirect nasopharyngoscopy, through the anterior rhinoscopy, after the nasal mucosa is fully converged, the red block of nasopharynx can be seen to be elevated in some patients; while in the indirect nasopharyngoscopy, the red block of nasopharynx can be seen to have the red block of elevation in the posterior wall of nasopharyngeal apex, and the surface can be presented as an orange petal shape. 4. Sleep respiratory monitoring: patients with adenoid hypertrophy are often accompanied by nocturnal apnea, hypoventilation and hypoxia, etc. The impact of hypertrophied tissues on respiratory physiology can be assessed by sleep respiratory monitoring. Adenoid hypertrophy, can go to the hospital to improve the above examination, to clearly diagnose and assess the severity of the patient’s condition.
