Patient ReportsLaryngeal Cleft: Symptoms, Causes, Diagnosis and Treatment
Written by Medicover Team and Medically Reviewed by Dr Shashi Kiran Somala , ENT
Table of Contents
Laryngeal Cleft is a rare congenital condition in which there is an abnormal opening between the larynx (voice box) or trachea (windpipe) and the esophagus. This defect allows food and liquids to enter the airway, increasing the risk of choking, aspiration, recurrent lung infections, and breathing difficulties. The severity of symptoms depends on the size of the cleft. Early diagnosis and appropriate treatment are important to protect the airway, improve feeding, and prevent complications.
What are the Symptoms of Laryngeal Cleft?
The symptoms of a laryngeal cleft can vary depending on the severity of the cleft. Common symptoms include:
- Difficulty swallowing (dysphagia)
- Chronic coughing or choking, especially during feeding
- Respiratory distress
- Frequent respiratory infections
- Hoarseness or a weak cry in infants
Laryngeal Cleft and Swallowing Difficulties
Swallowing difficulties are a hallmark symptom of laryngeal cleft. Due to the abnormal connection between the airway and the esophagus, individuals may aspirate food or liquid, leading to coughing and choking. This can also result in recurrent respiratory infections as foreign materials enter the lungs.
What are the Causes of Laryngeal Cleft?
The exact cause of laryngeal clefts remains largely unknown. However, it is believed to be a result of embryological development issues during the early stages of fetal growth. Genetic factors may also play a role, but no specific genetic mutations have been consistently linked to laryngeal clefts.
Laryngeal Cleft and Genetic Factors
Research indicates that some laryngeal clefts might be associated with genetic syndromes, such as Pallister-Hall syndrome or Opitz G/BBB syndrome. However, these cases are rare, and most laryngeal clefts occur sporadically without a clear hereditary pattern.
When to See a Doctor for Laryngeal Cleft?
Infants and children with choking during feeds, recurrent pneumonia, poor weight gain, or persistent aspiration should be evaluated by a ENT Specialist or Pediatric Surgeon as early diagnosis improves outcomes.
You should see a doctor if your child has:
- Repeated choking or coughing during feeding
- Frequent respiratory infections
- Poor feeding or inadequate weight gain
Seek emergency medical attention if your child:
- Develops severe breathing difficulty
- Shows bluish lips or skin
- Experiences repeated aspiration with respiratory distress
These symptoms may indicate significant airway compromise requiring urgent medical care.
How is Laryngeal Cleft Diagnosed?
Diagnosing a laryngeal cleft requires a thorough medical evaluation, often involving multiple diagnostic procedures. An accurate diagnosis is critical for determining the appropriate treatment plan.
Diagnostic Procedures
- Endoscopy: A flexible tube with a camera is inserted through the nose or mouth to visualize the larynx and esophagus.
- Bronchoscopy: This procedure allows doctors to examine the airways and lungs for any abnormalities.
- Swallow Study: A specialized X-ray test, known as a videofluoroscopic swallow study (VFSS), assesses swallowing mechanics and identifies any aspiration.
What are the Treatment Options for Laryngeal Cleft?
The treatment for laryngeal clefts depends on the type and severity of the aperture. In mild cases, non-surgical interventions may be sufficient, while more severe cases often require surgical correction.
Non-Surgical Treatments
For minor laryngeal clefts, treatment may involve:
- Thickened Fluids: Modifying the consistency of liquids can help prevent aspiration.
- Feeding Therapy: Specialized therapy can improve swallowing techniques and reduce the risk of aspiration.
- Speech Therapy: This can assist with any speech or vocal issues associated with the aperture.
Surgical Interventions
In more severe cases, surgery is often necessary to correct the cleft. Surgical options include:
- Endoscopic Repair: A minimally invasive procedure that uses specialized instruments to close the aperture through the mouth.
- Open Surgical Repair: Involves making an incision in the neck to access and repair the cleft. This approach is typically reserved for more complex cases.
Post-Surgical Care
Post-operative care is crucial for ensuring a successful recovery. Patients may require:
- Monitoring for Complications, Such as infection or airway obstruction.
- Continued Speech and Feeding Therapy: To support recovery and adaptation to changes post-surgery.

What is the Recovery Process for Laryngeal Cleft?
Recovery depends on the severity of the cleft and the type of treatment performed. Most children experience significant improvement in feeding and breathing after successful surgical repair, although swallowing therapy may be needed during recovery.
Long-term follow-up helps ensure normal airway function, safe swallowing, and healthy growth.
Recovery Includes
- Regular follow-up with a pediatric ENT specialist.
- Swallowing and feeding therapy.
- Monitoring for aspiration or recurrent infections.
- Nutritional assessment and growth monitoring.
- Following postoperative care instructions.
- Gradual return to age-appropriate feeding.
Frequently Asked Questions
1. What are the symptoms of Laryngeal Cleft?
Symptoms may include coughing, choking, and respiratory distress, indicating a defect in the larynx affecting airway function.
2. What causes Laryngeal Cleft?
Causes are often congenital, resulting from abnormal embryonic development of the larynx during fetal growth.
3. How is Laryngeal Cleft Diagnosed?
Diagnosis typically involves clinical evaluation, laryngoscopy, and imaging studies to assess the extent of the cleft.
4. What are the treatment options for Laryngeal Cleft?
Treatment often involves surgical intervention to repair the cleft and restore normal airway function.
5. What complications can arise from Laryngeal Cleft?
Complications may include chronic respiratory issues and significant impacts on feeding and quality of life if not managed effectively.
