What is Laryngeal Atresia?
Laryngeal atresia is an extremely rare condition. During the early part of the baby’s development, the voice box (larynx) does not form correctly. It stays closed and does not open once the baby is born. This causes severe breathing problems for the baby at birth.
Sometimes a baby with laryngeal atresia may have other serious problems with their airway.
Diagnosis
Laryngeal atresia is often found during a routine prenatal ultrasound. But it may go unnoticed during pregnancy. If discovered at birth, the baby will have severe breathing problems.
Initial Lifesaving Measures
If the condition was not found during pregnancy, once the baby is born an incision is immediately made into the lower part of the windpipe (trachea) to allow them to breathe. A trach tube is placed through this opening and breathing is done through this tube rather than through the nose and mouth.
If the laryngeal atresia is found before birth, the baby is delivered by the ex-utero intrapartum treatment procedure (called EXIT). The EXIT procedure is performed in an operating room equipped to treat mother and baby in one location.
Treatment
Once the infant is stable, a team of specialists performs a thorough exam. These doctors, members of the Cincinnati Children’s Aerodigestive Center, will discuss their findings and treatment plan with you. The focus of early treatment is to get the baby ready for surgery to repair the airway. This may include treating any conditions that may affect the success of the surgery.
In most cases, open laryngeal reconstructive surgery is indicated. This surgery involves placing grafts in the airway to make the airway bigger. A stent is typically placed in the airway to keep the grafts in place while they heal. During this time, the patient’s tracheotomy tube will remain in place.
Surgery for these children is challenging, and many children need more than one operation before removing the tracheotomy.
Long-Term Outlook
Many children with laryngeal atresia require multiple operations during their lifetime. They may have voice problems as they grow. Their voice will sound different because it will not come from the vocal cords. Such post-surgical voice problems are managed by a team of voice experts at Cincinnati Children’s Center for Pediatric Voice Disorders.
