Choanal atresia
Clinical Classification Guidelines
Inclusion Terms
- Atresia of nares (anterior) (posterior)
- Congenital stenosis of nares (anterior) (posterior)
Medical Intelligence & Overview
Choanal atresia is a congenital condition characterized by a blockage of the back of the nasal passage (choanae) that connects the nose to the throat. This blockage can be caused by abnormal bony or soft tissue growth, leading to difficulty breathing through the nose. The condition is present at birth and can affect one or both sides of the nose. Recognizing and understanding this condition is essential for early management and treatment to ensure proper breathing and development in affected infants.
Causes & Symptoms
Clinical Causes: Developmental abnormalities during fetal growth lead to incomplete formation of the nasal passages. Genetic factors may contribute to the occurrence of choanal atresia, sometimes associated with syndromes such as CHARGE syndrome. Environmental factors during pregnancy are suspected but not definitively linked to the condition.
Key Symptoms: Breathing difficulties, especially noticeable during feeding or lying down Noisy breathing or nasal congestion Cyanosis (a bluish tint to the skin), particularly when the baby is feeding or crying Inability to breathe comfortably through the nose Frequent respiratory infections
Diagnostic & Treatment
Diagnosis Path: Diagnosis is typically made based on physical examination and confirmed through imaging studies such as a computed tomography (CT) scan or nasal endoscopy. These tests help determine the location, extent, and type of atresia, whether bony, soft tissue, or mixed. In newborns, a failure to pass a small catheter through the nasal passage may also raise suspicion of choanal atresia.
Treatment Protocols: Treatment involves surgical intervention to remove the obstruction and restore normal nasal airflow. Surgical options include transnasal endoscopic procedures, which are minimally invasive and allow precise removal of abnormal tissue or bone. Postoperative care may involve nasal stents to prevent restenosis and medications to reduce inflammation. Early diagnosis and intervention are crucial for preventing complications and supporting proper breathing and development.
