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.

Craniodiaphyseal dysplasia is a rare genetic disorder of bone due to modelling errors of long bones and skull bones. Facial and cranial thickening and distortion are particularly striking in this form. The genetic understanding of this disorder is unsatisfactory. We present one case of Craniodiaphyseal dysplasia involving facial bone, skull that causes nasal obstruction. This 3-year old female who was diagnosed of craniodiaphyseal dysplasia presented abnormal facial figuring, which is excessively thickened cortical bone resulting in very large craniofacial bony structure. The patient sufferred from respiratory difficulty due to complete obstruction of choana. We performed surgical recanalization of choanal atresia by transpalatal approach and gained good postoperative result.

Bilateral choanal atresia in the neonate should be corrected surgically as soon as possible after maintaining the airway with Mc-Govern nipple. The treatment of choice is the transnasal endoscopic removal of the atretic plate including posterior inferiorpart of the bony nasal septum using microdebrider and drill. Although many authors propose not using postoperative stent, thismight not be applied to the neonatal bilateral cases. A description of the practical stenting technigue will be provided.
