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.

Nasal hump open roof deformity.

Nasal osteotomies are a cornerstone step for closing an open roof deformity after dorsal hump surgery. Notwithstanding the optimal method of nasal osteotomy remains controversial as evidenced by the variety of approaches with no consensus between authors. An open roof deformity is created by not performing osteotomies after the hump has been removed. Moreover the election of the technique responds to surgeon s preference.

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. On profile view a large dorsal hump causes the nose to look like it has a big bump. An open roof deformity is a term used to describe the appearance of the nose after a large dorsal hump reduction. When a large dorsal hump is reduced the bridge dorsum of the nose appears flat this is an 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.
