“…Choanal atresia is an uncommon congenital disorder in which the back of the nasal passage (choana) is blocked, usually by abnormal bony or soft tissue (membranous) due to failed recanalization of the nasal fossae during fetal development [ 1 – 3 ]. The incidence of congenital choanal atresia is about 1: 5000 to 1: 8000 [ 1 , 2 ].…”

Successful Noninvasive Respiratory Management of an Infant with Bilateral Choanal Atresia and a Supernumerary Nostril Located on the Columella by a Mouthpiece: A Case Report

Patient: Female, Newborn Final Diagnosis: Bilateral choanal atresia and a supernumerary nostril located on the columella Symptoms: Respiratory distress Clinical Procedure: — Specialty: Pediatrics and Neonatology Objective: Rare disease Background: Choanal atresia with a supernumerary nostril located on the columella is extremely rare. Infants are obligate nasal breathers because the oral airway is invariably blocked during calm respiration. Infants breathe through the mouth only during crying, and they only have nasal breathing until 5 months of life. Congenital nasal anomalies have been reported to be fatal from birth, requiring tracheal intubation or tracheostomy in the early post-natal period. In these cases, it is crucial to maintain an adequate airway. Case Report: A 2948-g female infant was born at 40 weeks by normal vaginal delivery. Her Apgar scores were 9 and 9 at 1 and 5 min, respectively. She had retractive breathing, cyanosis, and a supernumerary nostril at birth. She had no other anomalies. Computed tomography showed bilateral membranous choanal atresia. She needed nasal continuous positive pressure or a high-flow nasal canula for oxygen desaturation during crying, apnea, and dyspnea. However, her respiratory symptoms did not improve completely. On day 25 of life, she was given a mouthpiece to support mouth breathing. Her respiratory symptoms improved gradually, and she was discharged on day 73 of life with a mouthpiece. Conclusions: A very rare case of choanal atresia with a supernumerary nostril located on the columella was described. A mouthpiece was effective for breathing, obviating the need for emergency surgical intervention in the early postnatal period. Emergency procedures were avoided, probably because this case involved incomplete bilateral membranous choanal atresia rather than complete bony atresia.

“…2 Stenting is known to minimize the risk of restenosis, but it can lead to infection, scars (especially to septal, alar cartilages, and columella), and granulation formation with the possibility of restenosis. 2 , 5 This leads to stents in children with a higher risk of failure, including neonates and bilateral choanal atresia cases. A new reinforced choanal atresia stent patent was granted from the UK (Patent No.…”

Background Choanal Atresia is an obliteration by an atretic plate of the posterior choanae due to a failure of the bucconasal membrane to rupture. The insertion of stents post choanal atresia repair is familiar. Still, there are limited studies in the literature that specify the time to remove it, the best materials, and the effectiveness of each kind. Objective Our study aims to compare different types of choanal atresia stents and flaps and the outcome of different kinds of stents and flaps that use post-operatively. Also, to assess the risk of restenosis post-operatively with varying types of Stent and flaps. Methods A systematic review via databases for different types of stents and flaps used in choanal atresia, including 31 studies with precise technique, variety of stents, restenosis rates, and risk factors (unilaterality, the component of the atretic plate). And about 10 different approaches to flaps reconstruction were mentioned. Results According to the data, we observed a successful rate of choanal atresia repair by using the ordinary ETT post-operatively ranged from 28 to 94.2%, which could be explained due to many factors. Post-operative Instructions on care and suctioning provided a good impact. Other types of stents found in case series like steroid eluting stents, Nelaton catheters, Silastic stents, or modified ETT have a promising future during 26 to 39 weeks follow-up. Still, they need further studies with randomization and more data. Flaps with different approaches and techniques showed promising results and fewer complication rates with or without stents, also now have been used in practice providing suitable alternatives for stents. Conclusion The original types of choanal atresia stents were shown to have a wide variety of results, while innovative materials of stents showed promising results, however, in relatively small case studies. Flaps were now used in practice giving other choices for stents with fewer complications, better healing, and new choana formation.

Background Surgery on bilateral choanal atresia surgery is challenging and this case is rare in adults. In addition, stenosis issue postoperatively is commonly seen. Case presentation Transnasal endoscopic neochoanal technique was performed on a 27 years old female with the detailed surgical procedure was described. Neither stent nor nasal tamponade was applied. Ten months follow-up revealed a patent-wide neochonae. Discussion Transnasal endoscopic neochoanal technique without stent and nasal tamponade can be considered the procedure of choice in the management of CA cases. Conclusions Transnasal endoscopic neochoanal technique is considered an effective surgical procedure on bilateral choanal atresia.
