Background: Lateral osteotomies are used in rhinoplasty to narrow the nasal bones, close the open roof deformity after hump removal, and achieve symmetry of an asymmetrical framework. But this procedure causes periorbital oedema & ecchymosis. Different techniques have been described for lateral osteotomy.
Objective: To compare the postoperative ecchymosis and oedema after buccal sulcus lateral osteotomy versus intranasal lateral osteotomy.
Methods and materials: In a prospective experimental study, buccal sulcus approach was performed on the right side and an intranasal approach performed on the left side of patients randomly. Then blind analysis of postoperative photographs was performed to determine the incidence of oedema and ecchymosis on each side.
Results: Fifty patients were enrolled in the study after exclusion of unfit patients. On the right side (buccal approach osteotomies), a significantly lower incidence of upper and lower eyelid oedema and upper eyelid ecchymosis was seen on both the 2nd day and after 7th day (P < 0.05). The odds ratio of progression of ecchymosis was 2.66 (OR = 2.66, 95% CI: 1.09-5.52, p = 0.048) in intranasal group compare to buccal sulcus group. No significant complication observed.
Conclusion: The buccal sulcus approach is a safe method for lateral osteotomy with a lower rate of postoperative oedema and ecchymosis and no significant complications.
