Abstract

BACKGROUND AND OBJECTIVES
Hump resection by osteotome or rasp is a commonly used surgical technique in hump correction. However, during this procedure, the structure of the osseous-cartilaginous framework is altered and may lead to an open roof deformity or dorsal irregularity. So we preserved the hump as much as possible, and then augmented the radix with silicone. We compared this result to that of the hump resection group.
SUBJECTS AND METHOD
We retrospectively studied 21 patients who underwent rhinoplasty with hump correction. We classified the patients into two groups by operation technique; hump preservation and hump resection. The result of surgery was evaluated by comparing nasal measurements on pre and postoperative photos. Patient's satisfaction about cosmetic results were investigated using the visual analogue scale (VAS). All results were statistically tested.
RESULTS
The hump preservation group (N=13) had 12 cases (92.3%) of isolated hump type and one pseudo hump type (7.7%), whereas the hump resection group (N=8) had 5 cases (62.5%) of generalized hump type and 3 isolated hump type (37.5%). The preoperative nasofrontal angle in hump preservation (129.4degrees+/-10.6) was significantly lower than that in the hump resection group (139.3degrees+/-8.2). The nasion/nasal tip depth ratio in the hump preservation group (0.22+/-0.1) was also lower than that in the hump resection group (0.29+/-0.1) preoperatively; but there was no significant difference between the two groups. VAS was improved significantly in both groups after surgery.
CONCLUSION
Hump preservation and radix augmentation can be an effective and less complicated surgery for patients who have an acute nasofrontal angle with an isolated hump.
