Congenital atresia of the khoans arises due to the fact that in the embryonic period the mesenchymal tissue covering the lumen of the choana as a membrane does not completely or partially dissolve. In one of 7,000 cases, a newborn baby can not breathe through the nose. A defect is diagnosed at birth, when both passes are blocked. If one pass is blocked, the diagnosis can be made later, usually when there is a leakage of mucus from only one nostril. Recovery of the khohans involves surgical intervention. In this case, a CT scan is done to confirm the diagnosis.
Overview of the types of surgery
The operation is performed under general anesthesia. The surgeon can conduct it in two ways: transnazalno (the introduction of instruments through the nostrils) or transpalatally (an incision is made in the sky), taking into account the anatomy of the nasal passages. The operation is carried out through the nose, if the passages are blocked by a tissue, and a cut is made in the sky if the passages are blocked by a bone. In both cases, the lumen of the koan is formed with the help of nasal stents, which are removed after 6 months.
Postoperative period
After surgery, the baby can breathe normally and can be fed from a bottle. The newborn is left in the hospital under observation for a few days, older children, who have only one nasal passage restored, are discharged a little earlier. The doctor will tell in detail how to take care of the nasal passages so that the child can breathe freely through the stents until they are extracted. Do not also forget about possible complications (inflammatory process or bleeding), with the observation of which you should immediately go to the hospital. After extracting the nasal stents, the doctor will check the airways with an endoscope.
Why it should be done
During the operation, nasal passages are opened so that the child can breathe freely in the future. Newborns in the first weeks of life can breathe only through the nose (excluding crying).
Effectiveness of the operation
Usually the operation gives an excellent result. In most cases, only one surgical intervention is required, but in rare cases - the procedure is repeated (when the nasal passages are closed again).
[Risk factors
In general, the risk is the need for a repeat operation if the nasal passages are closed again. In general, there is an insignificant risk of complications - bleeding or inflammation. Any surgical intervention with the use of general anesthesia has a small degree of risk. Immediately contact the doctor if the child has bleeding, high fever, pus flowing and the baby can not breathe through the nose, as the stents are clogged. In rare cases, during the operation, nasal passages and the skull are injured.
What to think about
The operation can be postponed to 2-3 years in case of blocking one of the channels. Tranasal intervention is faster than transpalital, but further has a greater risk of closing nasal passages.
