This disease is present right from birth.  The patients with choanal atresia have obstructed or narrowed nasal passage  that causes difficulty in breathing. It occurs due to abnormal development of  the internal structure of the nose during fetal growth. If present in one nose,  it results in the discharge of mucus. The presence of choanal atresia in both  the nose may cause the infant shortness of breath. As the newborns cannot  breathe from their mouth, the condition of obstruction of both the nasal  passage is considered a medical emergency and requires immediate management.<\/p>\n<h2>What Are The Symptoms Of Choanal Atresia?<\/h2>\n<p> The  symptoms experienced by the patient depend upon unilateral or bilateral choanal  atresia. Patients experience severe symptoms in the case of bilateral choanal  atresia. The patients may have acute respiratory distress. They also have  cyanosis that becomes better with crying. However, the cyanosis returns at  rest. Episodes of choke and progressive airway obstruction result in feeding  difficulty. It is because of the inability of the infant to breathe and eat  simultaneously. <\/p>\n<p> The  symptoms of patients with unilateral choanal atresia are less severe. They rarely  experience respiratory distress conditions. However, they may have persistent  discharge from the nostril of the affected side. Further, they may also have  the problem of chronic sinusitis. Choanal atresia is associated with various  other conditions. The most common being CHARGE syndrome that may cause ear  problems, genital disease, heart disease, and mental retardation. <\/p>\n<h2>What Are The Types Of Choanal Atresia?<\/h2>\n<p> Depending  upon the single or both nasal pathways involved, there are two types of choanal  atresia. These are:<\/p>\n<ul>\n<li><strong>Unilateral  choanal atresia:<\/strong> It is a more common type of choanal atresia than  bilateral choanal atresia. In this condition, there is a blockage on one side  of the nose. The nose block is usually on the right side. The infant  compensates for the obstruction by breathing from the open nostril.<\/li>\n<li><strong>Bilateral  choanal atresia:<\/strong> It is characterized by blockage in both the nostril.  It is a dangerous situation as babies do not breathe from their mouths. It may  result in cyanosis.<\/li>\n<\/ul>\n<p>Both types  of choanal atresia are further divided into the following types:<\/p>\n<ul>\n<li><strong>Bone and  soft tissue blockage:<\/strong> The blockage is formed of bones and soft tissues. It  occurs in almost 70% of cases of choanal atresia.<\/li>\n<li><strong>Bone  blockage: <\/strong>In this type, the blockage is made up of only the bones. It  constitutes around 30% of the cases.<strong><\/strong><\/li>\n<\/ul>\n<h2>What Is The Prevalence Of Choanal Atresia?<\/h2>\n<p>The  incidence of choanal atresia is around 1 in 5000 to 1 in 8000 live births. It  is twice as common in females as males. Unilateral is more common than  bilateral with a ratio of incidence of about 3:2.<\/p>\n<h2>What Are The Causes Of Choanal Atresia?<\/h2>\n<p> The exact  cause of choanal atresia remains unknown. However, researchers believe that it  is a combination of environmental and genetic factors. It has been found that  mothers who took thyroid drugs have a higher incidence of choanal atresia in  their babies. However, it is not clear whether this increased risk is due to  the thyroid disease itself or the thyroid drugs.<\/p>\n<p>Several  other conditions occur along with the choanal atresia. These conditions are CHARGE  syndrome, Treacher Collins syndrome, Crouzon syndrome, Tessier syndrome, Coloboma,  and Genital hypoplasia.<\/p>\n<h2>How Doctor Diagnoses Choanal Atresia?<\/h2>\n<p> The doctor  diagnoses bilateral choanal atresia soon after the birth due to difficulty  breathing in the infant. The doctor then performs a further examination to rule  out the presence of other causes of nasal obstruction. The doctor inserts the  thin plastic tube from the nostril to the pharynx. If the blockage is present,  it may not pass through it. <\/p>\n<p> The doctor  may also perform the imaging tests such as CT scans and MRIs. This test may  help the doctor to rule out the other causes of nasal obstruction. Further,  with the help of imaging techniques, the doctor may also determine the anatomy  and thickness of the bony plate.<\/p>\n<h2>What Are The Treatments For Choanal Atresia?<\/h2>\n<p> Treatment  depends upon the severity of the condition and symptoms of the infant. Usually,  the patients with unilateral choanal atresia do not require treatment and are  under frequent monitoring of the clinicians. However, it is necessary to keep  their open nose clear. For this, the doctor may prescribe a saline solution.<\/p>\n<p> Surgery is  the only option in patients with bilateral choanal atresia. The doctor performs  the surgery as soon as possible. The patient is kept on nasal tube breathing  until surgery. The surgery may be through endoscopy or open procedure depending  upon the condition. <\/p>\n<h2>What Is The Outlook Of Choanal Atresia?<\/h2>\n<p>Babies with  unilateral choanal atresia do not have any problem most of their life. During  surgery in bilateral choanal atresia, the surgeons remove the tissues that  obstruct the passage. Thus, after surgery, the patient leads a healthy life. <\/p>\n","protected":false},"excerpt":{"rendered":"<p>Choanal atresia is a congenital condition. This disease is present right from birth.
