facial bipartition
Surgical technique that divides the midface vertically to correct hypertelorism and midface width abnormalities.
Full Definition
Facial bipartition is an advanced craniofacial procedure that involves splitting the midface down the midline and repositioning the orbital-maxillary segments to correct excessive intercanthal distance and facial width. This technique is commonly used in patients with frontonasal dysplasia, median facial clefts, or certain craniosynostosis syndromes. The procedure requires precise osteotomies through the nasal bones, maxilla, and orbits, followed by medial repositioning of the facial segments. Bone grafting is typically required to fill gaps created by the repositioning.
Usage
Usage note: Reserved for cases with significant hypertelorism that cannot be corrected by other means.
