SOME otolaryngologists who have tried the intranasal approach for the correction of bony choanal atresia of the posterior nares1-8 have brought to my attention the difficulty they encountered in obtaining a permanent opening. Their problem was the closure of the opening created, reverting back to an atresia, requiring additional surgery with no better results. Dilating instruments and graduated catheters were used over a period of months in a vain effort to obtain a permanent opening. Such procedures are unsatisfactory and very troublesome.
I have therefore been prompted to write this paper to point out and explain the reasons for this failure. Chances are that it resulted from a fault in the technique, due to the unsuccessful and improper covering of the newly created bony opening with the mucous membranes present. A permanent opening can and must be obtained if the intranasal technique is properly adhered to, and followed.
