Deneckc and Meyer first proposed excising the alar margin during bilateral cleft lip-nose repair. This technique later expanded to include alar base resection for alar ptosis correction and nasal reduction. The ptotic alar margin is identified and excised. Extended resection may extend the incision to the nasolabial fold, but careful reconstruction is essential to maintain a smooth, natural alar contour.
2.Lateral Nasal Alar Cartilage and Inferior Septal Cartilage Trimming Technique:
Proposed by McKinney and Stalnecker (1984), this involves partial resection of the inferior margin of the lateral nasal alar cartilage and the septal cartilage at the nasal tip to elevate the alar base. This technique is only suitable for patients with thin skin. Resection of the inferior septal cartilage is an effective method for elevating both the alar base and columella.
3. Partial Resection of the Nasal Alar Lining:
Through an intranasal incision between the cartilages, a strip of skin lining the upper margin of the lateral alar cartilage is excised, also achieving alar elevation. However, this technique may cause irregular alar margins or notching deformities and should be performed with caution.
What preparations are required before alar defect repair?
1. Avoid taking aspirin-containing medications for two weeks prior to surgery, as aspirin reduces platelet coagulation function;
2. Patients with hypertension or diabetes must fully disclose their medical history during the initial consultation to enable the attending physician to confirm the surgical plan;
3. Confirm good health with no infectious diseases or other inflammatory conditions prior to surgery;
4. Avoid makeup before surgery;
5. Women should schedule outside their menstrual period.
