Wide nasal bridge
Page most recently updated 7 September 2026
This page focuses on wide nasal bridge as a morphologic feature of conditions that may also be associated with psychiatric manifestations, such as psychosis, mania, autism spectrum disorder, ADHD, OCD, and self-injurious behaviours. The page begins with a clinical definition of wide nasal bridge based on the standardized Elements of Morphology terminology, together with visual examples from the same source. This is followed by a list of conditions in which wide nasal bridge has been described in association with psychiatric manifestations.
Of note, to optimize clinical utility, the list does not include conditions associated with intellectual disability in the absence of other psychiatric features.
Each condition listed below is linked to a dedicated page within this resource. These pages describe the psychiatric manifestations associated with each condition, as well as other morphologic and broader clinical features, allowing the differential diagnosis to be considered from multiple perspectives.

Definition
Subjective: Increased breadth of the nasal bridge.
Note: 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 considered separately.
Synonyms: Broad nasal bridge.
