“…In the neonatal period when the habit of mouth breathing is in development (James & Hastings, 1932), a "cyclic cyanosis" (Fig. 3) is a frequent observation (Lebensohn, 1923;Hogeman & Toremalm;Key & Mendel, 1968;Dion & Tache). About one-third of the cases in the present study were diagnosed during this period.…”

A follow-up study on 82 patients with congenital choanal atresia revealed that the malformation was twice as common in females as in males and occurred on the right side only in 56% of the cases. The family histories, however, revealed no obvious hereditary trend, and a chromosome analysis showed no abnormalities. Additional malformations were observed in 49% of the patients, but with no constant pattern substantiating a syndrome. The findings of the present study indicate that the atresia may result from a persisting bucconasal membrane. In about 50% of the patients the nasal cavity was funnel-shaped with a posterior narrow end, but the height of the palatal vault did not differ from the normal. The frequency of otitis media and sinusitis was high, 31% and 21% respectively.

“…All operations were performed under general anaesthesia with trans/endonasal perforation of the atretic membrane. A plastic (Portex) tube of an inner diameter of about 3 mm in which an oval hole had been cut in the middle (Fearon and Dickson, 1968;Hogeman and Toremalm, 1968) was then passed through one nostril and led out of the other. The tube was fixed in front of the columella (Fig.…”

“…The nasal cavity formed as the lateral palatine processes fuse in posterior direction. There is absorption of thin membrane which separates the oral and nasal cavity forming the posterior choana [6]. The factors which may cause atretic choana are medial outgrowth of the vertical or horizontal process of the palatal bone and persistent mesenchyme with misdirection of developmental flow [7].…”

Bilateral Choanal atresia is a medical emergency. Corrective surgery is the mainstay of the treatment. Hegar's dilator was used in all cases to break the bony/membranous atretic plate. The 22 cases of choanal atresia all operated by the first author were included in this study. Eight cases were 1-5 year old with bilateral choanal atresia and all required immediate surgery as they had repeated attacks of respiratory distress and cycle of cyanosis. Eight cases were of CHARGE Syndrome. All the cases were operated under general anaesthesia. Hegar's dilators were used and nasal stents were placed in all cases. Although complete nasal patency was achieved by surgery, in 8 cases, neonates could not survive due to the CHARGE Syndrome. The mortality was unrelated to the surgery. The 14 cases which were not related to CHARGE Syndroma had a good postoperative recovery. 3 cases were above 15 years old with unilateral complete bony/membranous choanal atresia and they presented with continuos nasal discharge. Hegar's dilators are a safe and simple method of surgery for choanal atresia. Nasal stenting is mandatory to prevent restenosis.
