Wide nasal bridge
Broad nasal bridge
HP:0000431
What it means
Increased breadth of the nasal bridge (and with it, the nasal root).
Care should be taken to distinguish between increased width of bone and Fullness of paranasal tissue. A wide nasal bridge should be distinguished from Telecanthus and Hypertelorism. A wide nasal bridge can be either prominent or depressed, which should be coded separately.
