Abstract

The choanal atresia is considered as one of important disease processes in rhinology particular, and in otorhinolaryngology as general. This condition is worthwhile situation, because it might be presented as emergency circumstance especially if it is associated with bilateral and complete obliteration of posterior choanal of the nasal cavity. However, this condition is due to the congenital and developmental defect of the canalization of the posterior choana, therefore, the diagnosis of the bilateral and complete choanal atresia will become very suggestable among the distressed newborns with nasal breathing difficulties. Moreover, the missing of the diagnosis will be increased among the unilateral or partial disease. Thus, it becomes a challenge to find out different methods and maneuvers to diagnose it. In accordance, as one of many clinical trials to achieve the optimum, safest, simplest as well as diagnostic maneuver for the missed unilateral choanal atresia, we created this presented test, which was found to be very beneficial and helpful to discover the missed unilateral choanal atresia during the performance of adenoidectomy surgery. In the same context, I recommend to consider this simple and safe test as a routine step during the adenoidectomy procedure. Hence, the patient is anesthetized and this will facilitate the conduction of this test to exclude one of the unforeseen disorders, which exaggerates the obstructive manifestation of adenoid enlargement as well as it prevents the complete cure of the child after the adenoidectomy.
