Although the exact cause of laryngomalacia is not known, some factors may affect this condition:

1. Congenital Anomalies: Congenital anomalies in infants may contribute to the development of laryngomalacia.
2. Genetic Factors: Babies with a family history of laryngomalacia or other respiratory problems may be at increased risk.
3. Other Respiratory Problems: Other conditions that affect breathing can worsen the symptoms of laryngomalacia.

The most common symptoms of laryngomalacia are:

• Wheezing Breath: A loud, wheezing sound heard when the baby breathes. This occurs due to vibration of the soft tissue of the larynx.
• Feeding Difficulty: Some babies may have difficulty breathing while eating.
• Sleep Problems: Audible breathing during sleep and sleep pauses may be observed.
• Skin Colour Changes: Babies who have difficulty breathing may have blue skin colour changes (cyanosis). This condition requires urgent medical intervention.

Laryngomalacia is usually diagnosed by the following methods:

• Physical Examination: The paediatrician assesses the baby's breathing and voice for any abnormalities.
• Laryngoscopy: Direct visualisation of the larynx through an endoscope. This procedure can be used to better assess the condition.

Laryngomalacia usually improves spontaneously, but if symptoms become pronounced, the following treatment methods can be applied:

1. Monitoring: In mild cases, the doctor usually prefers to monitor the condition. Symptoms usually decrease with the growth and development of the baby.
2. Feeding Adjustments: Breathing difficulties can be reduced by changing the baby's position during feeding.
3. Surgical Intervention: If symptoms are severe and affect quality of life, surgical intervention for laryngomalacia may be considered. This is usually a procedure to make the larynx more open.

Babies with laryngomalacia usually see their symptoms decrease or disappear completely as they grow older. Most children recover between 18 months and 2 years of age. However, if symptoms persist or other breathing problems occur, additional medical evaluation and intervention may be needed.

Laryngomalacia is usually a benign condition and is not a concern for most babies. However, if symptoms worsen in any way, or if there is difficulty breathing, it is important to contact a health professional immediately. With treatment and monitoring, most babies can grow up healthy and regain normal respiratory function.
