columella
Pronunciation: kol-you-MEL-ah
The tissue column separating the nostrils, important in nasal surgery and aesthetics.
Full Definition
The columella is the narrow strip of tissue that separates the nostrils and extends from the nasal tip to the upper lip. In rhinoplasty, columellar positioning and shape significantly influence nasal aesthetics and function. Common concerns include columellar show, retraction, or asymmetry. Surgical modification may involve cartilage grafting, soft tissue repositioning, or scar revision. The columellar-labial angle is a key aesthetic measurement in nasal analysis.
Usage
Usage note: The adjective form is 'columellar,' as in 'columellar strut graft.'
