On profile view a large dorsal hump causes the nose to look like it has a big bump.
Nasal hump open roof deformity.
Medial and lateral osteotomies of the nasal bones are required after the hump removal to close the open roof flattop nasal deformity created by the hump removal itself.
The hump is removed with a scalpel essentially a slice of bone is taken away.
At the time of rhinoplasty osteotomies will re position the nasal bones in such a way as to close the open roof and achieve a result that is natural in appearance.
Open roof deformity is one of the most common and problematic deformities in revision rhinoplasties due to failure to perform or performing incomplete ineffective uneven or unilateral osteotomies between the nasal bones and the maxilla thus impeding a smooth medialization of the nasal bones after either hump resection or humpless dorsum narrowing.
Moreover the election of the technique responds to surgeon s preference.
After the bone is sliced away the nose looks great on profile view.
An open roof deformity is a term used to describe the appearance of the nose after a large dorsal hump reduction.
Nasal osteotomies are a cornerstone step for closing an open roof deformity after dorsal hump surgery.
When a large dorsal hump is reduced the bridge dorsum of the nose appears flat this is an open roof deformity.
