Dolichocephaly (derived from the ancient Greek, δολιχός meaning long) is a condition where the head is longer than would be expected,^[1] relative to its width. The skulls of Neanderthals show a marked dolichocephaly compared to other humans, past or present. In humans, scaphocephaly is a form of dolichocephaly.

Dolicocephalic dog breeds (such as German Shepherd Dogs) have an elongated nose. This makes them vulnerable to fungal diseases of the nose such as aspergillosis.^[2] In human the anierior posterior diameter (length) of dolichocephaly head is more than transverse diameter (width). It has a incidence of 1 in every 4200 babies.

It can present be in cases of Sensenbrenner syndrome, Crouzon syndrome, Sotos syndrome,^[3] as well as Marfan syndrome.

Although dolichocephaly may be associated with some other abnormalities, alone it is just a normal variation; unless symptomatic, it is nothing to worry about. Early diagnosis can be made by X-ray or ultrasonography. Treatment is not essential.
