An open roof deformity is a term used to describe the appearance of the nose after a large dorsal hump reduction.
Nasal hump open roof deformity.
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.
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.
Notwithstanding the optimal method of nasal osteotomy remains controversial as evidenced by the variety of approaches with no consensus between authors.
Moreover the election of the technique responds to surgeon s preference.
On profile view a large dorsal hump causes the nose to look like it has a big bump.
After the bone is sliced away the nose looks great on profile view.
The best way to explain an open roof deformity is to start by explaining hump reduction rhinoplasty.
Nasal osteotomies are a cornerstone step for closing an open roof deformity after dorsal hump surgery.
An open roof deformity is created by not performing osteotomies after the hump has been removed.
