- Webster’s Triangle is a triangular bony strut at the piriform aperture which represents the attachment point of the inferior turbinate.
- This is clinically important with performing a lateral osteotomy during rhinoplasty as the osteotomy should begin high on the piriform aperture above Webster’s triangle in order to avoid subsequent internal nasal valve collapse.
- This technique is termed the high-low-high lateral osteotomy, as you start high on the piriform aperture, proceed downwards into the maxillary groove (low), and then curve back upwards to the nasofrontal suture (high).
