Deformities

Fig. 3.1 Congenital deformities.

Abnormal fusion of the nasal processes is uncommon, and may result in varying degrees of deformity.

In this case, the nose is bifid with hypertelorism (the distance between the eyes being greatly increased). In milder cases, the bifid appearance of the nose is less marked, and may just appear as a rather "wide" nose.

Stenosis Choane

Fig. 3.3a, b Congenital atresia of one posterior choana. This congenital deformity may not present until adult life. A total unilateral obstruction from birth may cause suprisingly little trouble to the patient. If, however, the symptoms are marked, the atresia can be treated surgically with removal of the bony obstruction.

Bilateral atresia presents with dyspnea soon after birth. Immediate surgical correction is required. A membranous atresia may be perforated and dilated using metal sounds, but if the atresia is bony it must be opened with a drill, using either a transnasal or transpalatal approach. Indwelling portex tubes are left in place for up to six weeks postoperatively to prevent a recurrence of the stenosis. Choanal atresia is well demonstrated on a computed tomograph (CT) scan, which is diagnostic. The arrow indicates the bony choanal atresia, which can be compared with the normal size. Closure of the posterior choanae with choanal atresia is well seen on this fiberoptic photograph of the postnasal space (b).

Human Deformities
Fig. 3.4a, b Hemangiomas of the face and nose present in babies and are a cosmetic problem. Treatment is deferred, for regression in about 70% of affected children is completed by age seven.
Choanal Atresia Newborns

Fig. 3.5 Nasal glioma. This curious polypoid swelling presents in the noses of children or babies. A biopsy confirms the nasal glioma, which is usually an isolated entity attached to the septum. A CT scan is needed to exclude the possibility of an intracranial attachment, but this is rare. This is a benign lesion.
