The operative methods for the choanal atresia or stenosis are transseptal, transnasal, transpalatal and transmaxillary approaches. Among them, endoscopic transnasal approach provides excellent visualization and little age limitation. The use of CO2 laser in the management of choanal atresia enables the accurate incision and vaporization. We experienced a case of acquired bilateral choanal stenosis which developed after external irradiation for nasopharyngeal carcinoma. She presented with the symptoms of slowly progressive bilateral nasal obstruction and persistent nasal discharge for the past three years prior to visiting hospital. We successfully managed her by endoscopic transnasal repair with CO2 laser and found this technique to safe and simple.

Congenital Choanal Atresia is a relatively uncommon anomaly. Among various surgical approaches for treating this ailment that have been proposed to date, transpalatal and transnasal endoscopic approaches are the preferred methods for surgical treatments. Because restenosis is the most important post-surgical concern, some authors used topical application of mitomycin C in the choanal atresia and found it to be effective in the prevention and treatment of scar formation. We have experienced a case of right membranous choanal atresia and left membranous choanal stenosis which were treated with a transnasal endoscopic approach using powered instrumentations and topical application of mitomycin C without an application of prolonged stent. Eight months after the treatment, patent neochoanae remains without evidence of restenosis.

Choanal atresia is the congenital failure of one or both posterior nasal apertures to communicate with the nasopharynx. Coexisting congenital anomalies are 20% to 50% of patients. Bilateral choanal atresia almost always presents respiratory distress, sucking difficulty and cyanosis relieved by crying in the newborn. Bilateral choanal atresia in newborns and infants carries significant morbidity and mortality, therefore, prompt correction is required. Athelia is the absence of the nipple-areola complex. It is a rare entity that can be either congenital or acquired. Congenital athelia is always associated with amastia and a syndrome. We report a case of choanal atresia associated athelia, in term baby.

Congenital posterior choanal atresia is a rare congenital deformity. Due to the influence of nose and face and intellectual development, its preferred surgical treatment. But surgical treatment methods and technology are in dispute. The using of high resolution display systems combine with micro tools can effectively reduce postoperative scarring and adhesion formation which is the key point to prevent restenosis. There is also the focus of controversy whether should place an expansive tube after operation. Currently nasal endoscopic approach has become the first choice for otolaryngologist treating congenital posterior choanal atresia.

Choanal atresia is a rare congenital anomaly involving unilateral or bilateral posterior nasal choanal obstruction. Multiple associated anomalies have been described. We describe the case of a 1-month-old boy with bilateral choanal atresia, misdiagnosed after CT as a midline meningocele because the floor of the midline anterior cranial fossa was not ossified and secretion had accumulated in the obstructed posterior nasal choana.

BACKGROUND AND OBJECTIVES: The bilateral choanal atresia is a medical emergency for which surgery is the only and definite treatment. We performed an atretic bone perforation using Hagers dilators. The purpose of this study, then, is to evaluate the efficacy of this simple technique of perforation, dilation and stenting. MATERIAL AND METHODS: We studied five patients who underwent surgery for a complete bilateral bony atresia from 1994 to 2004. All the patients were newborn: two males and three females babies. The male female ratio was 1 : 1.5. Their age varied from 1 day to 4 days. The surgery was performed with Hagers dilators using the puncture and dilation technique. Stenting was carried out in all cases using a non cuffed endotracheal tube. RESULTS: The reestablishment of the nasal passage through a perforating atretic plate was considered a successful criteria of surgery. All the neonates had good nasal air passage after the perforation, dilation and stenting. Two of the patients who were with the CHARGE association died within 7 days due to causes unrelated to surgery. The other three patients had successful removal of stent after six weeks. There was no follow-up afterwards. CONCLUSION: The puncture, dilation and stenting technique by Hagers dilator is safe, quick and simple. It involves minimum blood loss and is without any complications. Stenting, therefore, is essential for preventing restenosis.
