An occasional finding on physical exam is an asymmetric appearance of the nose due to a positional deformity. Most likely, this results from an unfortunate position in utero. The nares in this case are asymmetric and slightly flattened towards the infant's right, even though the septum is still centrally located.

Positional Nasal Deformity
Viewed from below, one can more clearly appreciate the asymmetry of the nares and the angulation of the septum.

Positional Nasal Deformity
When the tip of the nose is compressed gently in the presence of a dislocated septum, the deformity appears to worsen. In this photo, the tip of the nose is actually beside the base of the septum. With positional deformity, the septum would stay straight, even if the nares appear uneven. Although some authors estimate the incidence of dislocated septum to be as high as 4%, in our experience this condition is quite rare. An experienced pediatric otolaryngologist can relocate the septum fairly easily, without surgery, if consulted early (within the first few days of life), so recognition of this condition and timely referral is important to prevent permanent deformity.

Dislocated Nasal Septum
At first glance, this infant also appears to have a positional deformity of the nose, but here the actual diagnosis is dislocated nasal septum (a dangerous look-alike which can result in permanent deformity if not corrected). One clue, present in this photo, is that the vertical axis of the nose deviates to the infant's left. With positional deformity, the nares may look asymmetric, but the nose itself is straight.

Dislocated Nasal Septum
From this view, the deformity is more easily seen. The septum is not straight and the whole bottom segment of the nose appears to be shifted to the baby's left (look towards the bridge of the nose to appreciate this). Compressing the tip of the nose gently can also help distinguish this condition from a positional problem, as the next photo demonstrates.
