Abstract: | The objective of this study is to assess the results of repairing septal perforations with a vascularized pedicled alar cartilage
island flap. Using the external rhinoplasty approach, a vascularized flap of alar cartilage, harvested as a cephalic trim
and pedicled on the ascending columellar branches of the superior labial artery was raised. Bilateral mucoperichondrial septal
flaps were elevated and the alar flap was transposed and secured within the defect and bilaterally overlaid with temporalis
fascia. Silastic sheets were placed and remained in situ until the grafts were revascularized from the peripheries of the
defect as well as centrally from the alar flap. The revascularized temporalis fascia acted as a scaffold for nasal remucosalization.
The alar flap also increased the long-term structural robustness of the repair. Between 1999 and 2003, 14 patients with septal
perforations ranging from 10 to 31 mm underwent septal reconstruction using this technique. There were nine males and five
females. The flap was successfully raised in all cases and long-term closure was maintained in 12 patients (86%). The alar
cartilage flap is an effective technique for repairing septal perforations in selected patients. It provides vascularized
tissue which nourishes the grafts during remucosalization, and a cartilaginous framework, which affords long-term structural
support to the repair. It also obviates the need to transpose nasal mucosa and create a secondary defect. The rhinoplasty
approach furthermore permits additional nasal deformities to be corrected at the same time.
