Comparative study of continuous lateral osteotomy and microperforating osteotomy in patients undergoing primary rhinoplasty

Abstract

Summary Introduction: Lateral osteotomies play an important role in rhinoplasty and can be performed with different techniques. Objective: To compare the results of narrowing of the nasal dorsum and base through 2 types of lateral osteotomy: continuous and microperforating. Method: We selected 74 patients undergoing rhinoplasty: 37 patients underwent lateral continuous osteotomy and the other 37 underwent microperforating osteotomy, all performed by the same surgeon. We analyzed frontal photography from the pre- and post-operative (6 months) periods, evaluating the width of the nasal dorsum and base. This was a retrospective study. Results and Conclusion: Using Student's t-test, statistical analysis concluded that there was a statistically significant difference in the post-operative narrowing of the nasal dorsum and base following both osteotomy techniques, and there was no statistically significant difference between the 2 techniques.

Lateral Osteotomy for the Surgical Treatment of the Asian Wide Nose

“…Our approach also reduced the risk of severe intraoperative bleeding, postoperative swelling, ecchymosis, and prolonged recovery, which have been associated with conventional lateral osteotomy procedures. 15 In fact, only mild edema and congestion were observed with our technique of osteotomy. Postoperative follow-up showed esthetic results, as confirmed by objective measurements and patient selfassessment.…”

“…It is important to note that a subcutaneous dead space can lead to the accumulation and organization of hematoma, which may impair bone healing at the fracture line, result in abnormal bone hyperplasia, and, ultimately, affect the postoperative outcome. Our approach also reduced the risk of severe intraoperative bleeding, postoperative swelling, ecchymosis, and prolonged recovery, which have been associated with conventional lateral osteotomy procedures 15 . In fact, only mild edema and congestion were observed with our technique of osteotomy.…”

“…In Caucasians, a transdermal lateral perforating osteotomy is often applied. 4,10,[13][14][15][16][17] However, in Asians, an external nasal incision is typically less accepted due to an increased risk of hypertrophic and, thus, obvious scarring. As a consequence, a skin incision is rarely selected for osteotomy.…”

“…A number of osteotomy methods have been previously reported for the treatment of wide nose. In Caucasians, a transdermal lateral perforating osteotomy is often applied 4,10,13–17 . However, in Asians, an external nasal incision is typically less accepted due to an increased risk of hypertrophic and, thus, obvious scarring.…”
