Definition

Choanal atresia is a medical condition where the passage between the nose and throat is blocked. This blockage can happen on one side (unilateral) or both sides (bilateral) of the nasal passage. It can affect newborns and older individuals, causing difficulty in breathing through the nose. Let’s break down this condition into simple terms to understand its types, causes, symptoms, diagnostic tests, treatments, medications, surgeries, preventions, and when to seek medical help.

Types of Choanal Atresia

  1. Unilateral Choanal Atresia: This occurs when only one side of the nasal passage is blocked.
  2. Bilateral Choanal Atresia: Both sides of the nasal passage are blocked, making breathing through the nose challenging.

Causes of Choanal Atresia

  1. Congenital: Choanal atresia often occurs during fetal development when the nasal passages fail to open properly.
  2. Genetic Factors: Sometimes, genetic factors can play a role, making certain individuals more predisposed to this condition.
  3. Environmental Factors: Exposure to certain environmental toxins or substances during pregnancy may increase the risk.

Symptoms of Choanal Atresia

  1. Difficulty Breathing: Newborns or infants may have trouble breathing through the nose, especially during feeding or sleeping.
  2. Nasal Discharge: There may be nasal discharge, which can be clear or bloody.
  3. Noisy Breathing: Breathing sounds may be loud or noisy due to the blocked nasal passages.
  4. Mouth Breathing: Babies may prefer breathing through their mouths instead of their noses.
  5. Feeding Difficulties: Difficulty in feeding due to trouble breathing while sucking.
  6. Failure to Thrive: In severe cases, where the condition is not promptly treated, babies may have trouble gaining weight and growing properly.

Diagnostic Tests for Choanal Atresia

  1. Physical Examination: A doctor may perform a physical examination to assess the nasal passages and breathing.
  2. Nasal Endoscopy: A thin, flexible tube with a camera (endoscope) is inserted into the nose to visualize the blockage.
  3. CT Scan: A computed tomography (CT) scan provides detailed images of the nasal passages and helps identify the blockage.
  4. X-ray: X-rays may be taken to assess the anatomy of the nasal passages and detect any blockages.

Non-Pharmacological Treatments

  1. Surgery: The primary treatment for choanal atresia is surgical intervention to open the blocked nasal passages.
  2. Nasal Stenting: In some cases, nasal stents may be placed temporarily after surgery to keep the passages open during healing.
  3. Nasal Irrigation: This involves rinsing the nasal passages with a saline solution to keep them moist and clear.
  4. Positional Therapy: Placing the baby in certain positions during sleep may help improve breathing.

Medications

  1. Antibiotics: Antibiotics may be prescribed if there is an associated infection in the nasal passages.
  2. Nasal Decongestants: These medications help reduce nasal congestion and may be used temporarily to relieve symptoms.

Surgeries for Choanal Atresia

  1. Transnasal Endoscopic Surgery: This minimally invasive procedure involves using an endoscope to remove the blockage and open the nasal passages.
  2. Transpalatal Surgery: In cases where endoscopic surgery is not feasible, an incision may be made through the roof of the mouth to access the blockage.

Preventions and When to See a Doctor

  1. Prenatal Care: Seeking regular prenatal care and avoiding exposure to harmful substances during pregnancy may help reduce the risk.
  2. Prompt Medical Attention: If a newborn exhibits symptoms such as difficulty breathing or feeding, noisy breathing, or persistent nasal discharge, it’s essential to seek medical help promptly.
  3. Regular Check-ups: Regular visits to a pediatrician can help monitor the baby’s growth and development, allowing early detection of any potential issues.

In summary, choanal atresia is a condition where the nasal passages are blocked, making breathing through the nose difficult. It can affect newborns and older individuals and may require surgical intervention to open the blocked passages. Early diagnosis and prompt treatment are essential for better outcomes. If you notice any symptoms in yourself or your child, don’t hesitate to seek medical advice.

Doctor visit helper

Prepare before seeing a doctor

A simple rural-patient checklist to help you explain symptoms clearly, ask better questions, and avoid unsafe self-treatment.

Safety note: This is not a prescription or diagnosis. For severe symptoms, pregnancy danger signs, children with serious illness, chest pain, breathing difficulty, stroke-like weakness, or major injury, seek urgent care.

Which doctor may help?

Start with a registered doctor or the nearest qualified health center.

What to tell the doctor

  • Write when the problem started and how it changed.
  • Bring old prescriptions, investigation reports, and current medicines.
  • Write allergies, pregnancy status, diabetes, kidney/liver disease, and major past illnesses.
  • Bring one family member if the patient is weak, elderly, confused, or a child.

Questions to ask

  • What is the most likely cause of my symptoms?
  • Which danger signs mean I should go to hospital quickly?
  • Which tests are necessary now, and which can wait?
  • How should I take medicines safely and what side effects should I watch for?
  • When should I come for follow-up?

Tests to discuss

  • Vital signs: temperature, pulse, blood pressure, oxygen saturation
  • Basic physical examination by a clinician
  • CBC, urine test, blood sugar, or imaging only when clinically needed

Avoid these mistakes

  • Do not use antibiotics, steroid tablets/injections, or strong painkillers without proper medical advice.
  • Do not hide pregnancy, kidney disease, ulcer, allergy, or blood thinner use.
  • Do not delay emergency care when danger signs are present.

Medicine safety and first-aid guide

This section is for patient education only. It does not replace a doctor, pharmacist, or emergency care.

Safe first steps

  • Avoid heavy lifting, sudden bending, and prolonged bed rest.
  • Use comfortable posture and gentle movement as tolerated.
  • Discuss physiotherapy, X-ray, or MRI only when clinically needed.

OTC medicine safety

  • For mild back pain, pain-relief medicine may be discussed with a doctor or pharmacist.
  • Avoid repeated painkiller use if you have kidney disease, stomach ulcer, uncontrolled blood pressure, or are taking blood thinners.

Avoid these mistakes

  • Do not start antibiotics without a proper medical decision.
  • Do not use steroid tablets or injections casually for quick relief.
  • Do not delay emergency care because of home remedies.

Get urgent help if

  • Back pain with leg weakness, numbness around private area, loss of urine/stool control, fever, cancer history, or major injury needs urgent care.
Medicine names, dose, and timing must be decided by a qualified clinician or pharmacist after checking age, pregnancy, allergy, other diseases, and current medicines.

For rural patients and family caregivers

Doctor / service to discuss: Qualified healthcare provider; specialist depends on symptoms and examination.
  1. Step 1

    Check danger signs first

    If danger signs are present, seek emergency care and do not wait for online information.

  2. Step 2

    Record the symptom story

    Write when symptoms started, severity, medicines already taken, allergies, pregnancy status, and test results.
