The condition almost always presents in the new born, with alternating phases of respiratory distress and apnoea relieved by crying. We report a rare case of bilateral choanal atresia presenting for the first time at 22 years of age. [ncbi.nlm.nih.gov]

We present monozygotic premature twin infants with identical findings of bilateral choanal atresia and no other associated anomalies. To our knowledge, this is the first report of such an occurrence. [nature.com]

• Feeding Difficulties

  This case report describes the multi-disciplinary team approach that included pedodontists to manage the case of a 6-month-old infant with choanal atresia suffering from breathlessness, feeding difficulty, and disturbed sleep. [ncbi.nlm.nih.gov]

  CT scan demonstrating bilateral choanal atresia The symptoms of choanal atresia include: Cyclic respiratory distress relieved with crying Noisy breathing Feeding difficulties Inability to pass a 5/6 French suction catheter into the nasopharynx Nasal drainage [chop.edu]

• Falling

  Parents should contact your GP if: their baby is having difficulty breathing their baby has yellowish ooze from his or her nose their baby is bleeding from his or her nose their baby has a high temperature of 37.5°C or higher the stents become loose or fall [gosh.nhs.uk]

  The respiratory obstruction is cyclic - as the child falls asleep the mouth closes and a progressive obstruction starting with stridor followed by increased respiratory effort and cyanosis. [drtbalu.co.in]

• Pain

  </p> <h3>You may give your child medicine for pain</h3> <p>You may receive a prescription for pain medication, before you leave the hospital. Follow the dosage instructions given to you by the pharmacist. [aboutkidshealth.ca]

  In neonates with isolated bilateral CCA, breast-suction could be started within 1 day (range 1-2 days), and pain-killers were needed on average for 1.5 days (range 1-4 days). [ncbi.nlm.nih.gov]

  There may be mild to moderate pain for a few days. Saline spray is used at home to help rinse the nose and keep it clean. [care.american-rhinologic.org]

• Weight Gain

  Non-nutritive sucking gives your baby a chance to practice at the breast, encouraging sucking and weight gain. [chop.edu]

  During routine checkups, the doctor will monitor your baby's weight gain and growth. Urine colour. The urine should be yellow. Don't be alarmed, though, if you notice a pink colour to the urine during your newborn's first 3 days of life. [healthlinkbc.ca]

• Trisomy 21

  Related conditions include cystic fibrosis, Trisomy 21 (Down syndrome), congenital heart disease, bowel rotational abnormality, annular pancreas, esophageal atresia, anorectal atresia and genitourinary conditions. [chop.edu]

• Rhinorrhea

  Unilateral can be either asymptomatic or present late with rhinorrhea or infection. [ajnr.org]

  Twenty patients were symptom-free after a single operation; nasal obstruction, rhinorrhea, and xerostomia improved significantly for these patients. [ncbi.nlm.nih.gov]

  Unilateral atresia may go unnoticed for years and present with Late rhinorrhea and unilateral nasal congestion, some patients, however, may remain mildly (7). [arquivosdeorl.org.br]

  It causes persistent rhinorrhea, and with bilateral choanal atresia and obstructed airway that can cause cyanosis and hypoxia. [en.wikipedia.org]

• Aspiration

  Possible complications include: Aspiration while feeding and attempting to breathe through the mouth Respiratory arrest Renarrowing of the area after surgery Choanal atresia, especially when it affects both sides, is generally diagnosed shortly after [nlm.nih.gov]

  Symptoms of bilateral choanal atresia also include : Aspirating milk (regurgitating milk into their lower airway) Noisy breathing Turning blue while sleeping or feeding Feeding slowly can allow the baby to breathe between swallows. [umiamihealth.org]

  Patients with bilateral choanal obstruction and patients with unilateral choanal obstruction or rhinitis showed no differences in clinical picture or in referral age. [ncbi.nlm.nih.gov]

  Antibiotics and decongestants are prescribed if there is evidence of rhinitis 3. Patients must be followed up regularly till the stents are removed. Copyright drtbalu 2007 [drtbalu.co.in]

• Tachypnea

  A differential diagnosis of presumed sepsis, cyanotic congenital cardiac disease, and Transient Tachypnea of newborn was made. A chest X ray was done which was normal. [jpma.org.pk]

• Failure to Thrive

  Maggie Rice (played by Meg Ryan) correctly diagnoses the cause of a newborn baby's failure to thrive as due to choanal atresia. [en.wikipedia.org]

• Cyanosis

  A 2-day-old full term male infant was presented with history of attacks of cyanosis, difficulty in suckling and respiration. On examination cyclical change of body colour, ie, alternating cyanosis and normal colour was observed. [ncbi.nlm.nih.gov]

  In the newborn because of the presence of the cyanosis and dyspnea the condition may frequently be misdiagnosed as asphyxia neonatorum. [jamanetwork.com]

  Choanal atresia blocking both sides (bilateral) of the nose causes acute breathing problems with cyanosis (bluish discoloration) and breathing failure. Infants with bilateral choanal atresia may need resuscitation at delivery. [nlm.nih.gov]

• Hearing Impairment

  impairment, and severe growth retardation. [ncbi.nlm.nih.gov]

  Because of these abnormalities, hearing isn’t likely to be fully restored to “normal” even with early intervention during childhood. Ultimately, the degree of hearing impairment will depend on how the inner ear mechanisms are affected. [hamiddjalilianmd.com]

• Ulcer

  Surgery of BCA in a newborn, who is usually underweight or premature in occasions, carry many hazards including, nasal septal perforation, [21] palatal perforation, columella ulceration/necrosis [22] and bleeding rarely leading to death [23] in addition [saudijhealthsci.org]

  During the period of stenting two children self removed the stents from the nose and in one patient a decubitous ulcer formation was observed in the area where the the stent touched the skin of anterior choanae. [czytelniamedyczna.pl]

  Because a stent may cause discomfort, localized infection and ulceration, along with circumferential scar tissue and injury to surrounding normal tissue. [waent.org]

  Repair without stenting reduces the intensity of post-operative management and avoids the potential for stent-related complications, such as discomfort, localized infection and ulceration, circumferential scar or granulation tissue formation (40). [ncbi.nlm.nih.gov]

• Broad Nasal Bridge

  The child also had dysmorphic features including a broad nasal bridge, telecanthus, downward slanting palpebral fissures, prominent ears, mild bilateral clinodactyly of the 5th fingers and bilateral hypoplasia of the 2nd-5th toenails. [ncbi.nlm.nih.gov]

  All were females (2 of them were twin sisters) and presented distinctive facial features: arched eyebrows (7 cases), prominent forehead (5 cases), broad nasal bridge (5 cases) and/or hypoplastic nasal ala (2 cases). [elsevier.es]

• Epistaxis

  Merocel epistaxis packing was used to pack the nasal airway for 3 days postoperatively. All of the patients underwent endoscopy regularly for follow-up. [ncbi.nlm.nih.gov]

Workup Computed tomography (CT) scanning is the radiographic procedure of choice in the evaluation of choanal atresia. For good results, careful suctioning is performed to clear excess mucus, and a topical decongestant is applied. [emedicine.com]

CT workup and histologic specimens show approximately 30% pure bone atresia and 70% mixed membranous and bone atresia with no purely membranous anomalies present. [statpearls.com]

The use of stent did not improve preventive rate of restenosis: 42.9% of restenosis with stent and 47.4% without stent, respectively. Mitomycin C did not seem to be effective in preventing restenosis either. [ncbi.nlm.nih.gov]
