Study of Effect of Resection of Cephalic Portion of Nasal Alar Cartilage on Nasal Tip Rotation
Abstract
Background: One of the most common techniques of nasal tip surgery in rhinoplasty is conservative resection of cephalic portion of nasal alar cartilage; although, there is a controversy about its effectiveness on nasal tip rotation in textbooks and articles. Therefore, in this research, we have studied the effect of conservative resection of cephalic portion of alar cartilage on nasal tip rotation.
Methods: 35 patients were selected from the patients who were candidates for septoplasty, after getting their agreement. In surgery we performed conservative resection of cephalic portion of alar cartilage. Nasolabial angles were calculated, using the lateral photographs of the patients before and six monthes after surgery. The means of these angles were analyzed with t-paired test.
Results: The means and standard deviations of nasolabial angles before and six months after surgery were 91.49±7.35 and 91.57±7.04, respectively. Calculated P-value was 0.52.
Conclusion: There was no meaningful difference between means of nasolabial angles before and six months after surgery (P-value was greater than 0.05). Therefore, in this research we concluded that conservative resection of cephalic portion of alar cartilage has no effect on nasal tip rotation.
