choanal atresia

Choanal atresia is a congenital condition that affects the nasal airway, making it harder for individuals to breathe. It occurs when excess tissue blocks one or both sides of the nasal airway, causing narrowing or blockage of the nasal passages.

Characteristics:

• Congenital: Choanal atresia is present from birth.
• Narrowing or blockage: The condition involves a narrowing or complete blockage of the nasal airway by tissue.
• Difficulty breathing: Individuals with choanal atresia may experience difficulty breathing, especially when trying to inhale.

Associations:

• CHARGE syndrome: Choanal atresia is often associated with CHARGE syndrome, a rare genetic disorder.
• Treacher Collins syndrome: The condition is also linked to Treacher Collins syndrome, a genetic disorder that affects the development of facial bones and other tissues.
• Tessier syndrome: Choanal atresia has been associated with Tessier syndrome, another rare genetic disorder.

Causes:

The exact cause of choanal atresia is not fully understood. However, it is believed to be related to abnormalities in the development of the nasal passages during fetal growth.

Choanal atresia is a congenital condition that affects the back of the nose, causing breathing difficulties in newborns. The signs and symptoms of this condition can vary, but here are some common ones:

• Recurrent nasal drainage: This is often the most common symptom, where one side of the nose has persistent mucoid discharge (1).
• Noisy breathing: Babies with choanal atresia may exhibit noisy or labored breathing, especially when they try to breathe through their mouth (6).
• Difficulty breathing: Breathing difficulties can occur, particularly if the condition is bilateral (affecting both sides of the nose) (2).
• Feeding difficulties: Some babies may experience feeding difficulties due to respiratory distress (3).
• Inability to pass a suction catheter: A healthcare provider may have trouble passing a 5/6 French suction catheter through one side of the nose, indicating a blockage (3).

It's essential to note that choanal atresia can be asymptomatic in some cases, and symptoms may not appear until later in life. However, if you suspect your baby is experiencing any of these symptoms, it's crucial to consult with a healthcare provider for proper evaluation and treatment.

Choanal atresia, a congenital disorder where the nasal choanae are occluded, can be diagnosed through various diagnostic tests.

Initial Clinical Evaluation

The initial clinical evaluation typically includes several tests to confirm the diagnosis:

• Introduction of a 6 or 8 French suction catheter via the nostrils [8]
• Methylene blue dye test [8]
• Cotton wisp test [8]
• Laryngeal mirror examination [2]

These tests help healthcare providers assess the nasal passages and determine if there is a blockage.

Imaging Studies

Imaging studies are also essential in diagnosing choanal atresia:

• Fiberoptic nasal endoscopy: This procedure allows doctors to visualize the nasal cavity and identify any blockages [9]
• Noncontrast axial CT scan: A CT scan can help determine the exact location and severity of the blockage [9]

Other Diagnostic Tests

Additional diagnostic tests may be performed, including:

• Saline and aspiration catheter test: This test involves introducing saline or a catheter into the nasal cavity to check for patency [7]
• Sinus x-ray: A sinus x-ray can help identify any abnormalities in the sinuses [6]

Diagnostic Imaging Centers

If you're looking for diagnostic imaging centers, there are several options available:

• Caresouth Carolina, Florence MRI & Imaging
• Southeastern Radiology
• OrthoSC MRI
• Image Care
• Clermont Radiology
• North Carolina Diagnostic Imaging
• Long Bay Diagnostic Imaging
• Carolinas Imaging Services - Rock Hill
• Carolina Forest Imaging Center [11]

These centers offer a range of diagnostic imaging services, including CT scans and X-rays.

Definition of Diagnostic

The term "diagnostic" refers to the process of identifying or determining the presence of a disease or condition. In the context of choanal atresia, diagnostic tests are used to confirm the diagnosis and determine the severity of the blockage [12].

[2] - Healthcare providers usually diagnose newborns with bilateral choanal atresia while they’re still in the hospital.

[7] - A positive saline and aspiration catheter test means that the saline or catheter does not pass through the nasal cavity into the pharynx.

[8] - Initial clinical evaluation includes introduction of a 6 or 8 French suction catheter via the nostrils, methylene blue dye test, cotton wisp test, and laryngeal mirror examination.

[9] - Fiberoptic nasal endoscopy and noncontrast axial CT scan are keys to diagnosis, with bilateral choanal atresia likely clinically evident earlier than unilateral.

Medical Management of Choanal Atresia

While surgery is the only long-term treatment for choanal atresia, medical management can provide temporary relief of symptoms. According to [6], medical management is generally reserved for temporary relief of symptoms.

• Emergency Treatment: In cases where both nasal passages are blocked (bilateral choanal atresia), emergency treatment usually consists of placing a plastic airway (tube) into the mouth to keep the mouth open, allowing the baby to breathe adequately [5].
• Intubation: The immediate treatment for children with this condition is to place a breathing tube so they can breathe adequately. Most children with choanal atresia require intubation to ensure adequate oxygenation [8].

However, it's essential to note that medical management is only temporary and does not address the underlying blockage in the nasal passage.

Surgical Treatment

Surgery is the definitive treatment for choanal atresia, aiming to restore the normal nasal passage. The ideal procedure involves restoring the normal anatomy of the nasal passage [3]. Surgical techniques include:

• Combined Transoral-Transnasal: This technique provides a good alternative for managing choanal atresia, with easier and more efficient surgery [7].
• Nasal Stents: To ensure the newly created holes stay open, surgeons place small plastic tubes (nasal stents) in each nostril, held in place by stitches [9].

While medical management can provide temporary relief, surgical treatment is essential for a long-term solution to choanal atresia.

Differential Diagnosis of Choanal Atresia

Choanal atresia, a congenital condition characterized by the blockage of the rear opening of the nasal cavity, can be challenging to diagnose due to its similarity with other conditions. The differential diagnosis for choanal atresia includes:

• Deviated or dislocated nasal septum: A condition where the thin wall of cartilage and bone between the two sides of the nasal passages is displaced or crooked, which can cause breathing difficulties [6].
• Turbinate hypertrophy: A condition where the turbinate bones in the nasal cavity become enlarged, leading to nasal obstruction [3].
• Septal hematoma: A collection of blood in the nasal septum that can cause nasal obstruction and other symptoms [1].
• Mucosal swelling: Inflammation or swelling of the mucous membranes in the nasal passages, which can cause breathing difficulties [1].
• Pyriform aperture stenosis: A congenital condition where the opening of the nasal cavity is narrowed, leading to breathing difficulties [2].
• Nasolacrimal duct mucocele: A condition where a small sac forms in the nasolacrimal duct, causing nasal obstruction and other symptoms [2].

These conditions can present with similar symptoms to choanal atresia, such as difficulty breathing or nasal congestion. Therefore, it is essential to perform a thorough diagnostic evaluation to determine the correct diagnosis.
