Objective To evaluate the curative effect of the lateral nasal artery pedicled nasolabial flap for reconstruction of nasal defects. Methods From August 2005 to March 2009, 12 cases of large nasal tip and alar defects were repaired with the lateral nasal artery pedicled nasolabial flap. There were 5 male patients and 7 female patients with a mean ageof 48.6 years (range, 35-60 years). Five cases of nasal defects were caused by trauma and other defects were caused by excision of carcinoma or hemangioma; the courses of disease were 1 to 10 years and 3 months to 40 years, respectively. The nasal defect size ranged from 2.0 cm × 1.5 cm to 4.5 cm × 2.5 cm. All defects were reconstructed with lateral nasal artery pedicled nasolabial flap in 9 cases and with island flap in 3 cases. The flap size ranged from 2.5 cm × 2.0 cm to 7.0 cm × 3.0 cm. Five patients required cartilage grafts for alar rim support and the distal end of the nasolabial flap was thinned and folded to repair the nasal l ining. The donor sites were sutured directly. Results The mild venous stasis at the distal end of three island flaps occurred at 5-24 hours postoperatively and alleviated spontaneously. All flaps survived. Incision at donor and accepted sites healed by first intention. Flap revision was performed in 5 cases after 6-15 months because of mild swell ing at the pedicles of skin flaps. All patients were followed up 8-24 months, with an average of 13 months. All patients achieved satisfactory results in nasal appearance, flap texture and color, and ventilatory function. No obvious scar was found at donor sites. Conclusion The nasolabial flap is an excellent choice for reconstruction of defects of nasal tip and ala.
ObjectiveTo explore the application and effectiveness of thin-ribbed cartilage with the perichondrium in the correction of secondary cleft lip nasal deformity as the lateral crural onlay graft.MethodsA retrospective study was performed based on the data of 28 patients with secondary nasal deformity of cleft lip between October 2015 and April 2017. There were 16 males and 12 females with an average age of 24 years (range, 18-31 years). There were 11 cases with secondary nasal deformities on the left side, 13 cases on the right side, and 4 cases on both sides. Three-dimensional stereotaxy of the nasolabial muscles was used to correct the deformity. The costal cartilage as the support was used to perform nasal columella and nasal dorsum while the thin-ribbed cartilage with the perichondrium was used as wing cartilage support. The photography of nasal position was taken before operation and at 6-8 months after operation. The midpoint of the junction between the nasal columella and the upper lip was marked point O; the lateral horizontal line passing through the point O was marked as X-line, and the longitudinal line (the midline) as Y-line. The distance of the highest point of the affected nostril to the X-line, the distance of the nostril’s outermost point to the Y-line, the symmetries of both the most lateral and the highest point of the bilateral nostrils, and the distance of the highest point of the nasal tip to the X-line were measured.ResultsAll incisions healed by first intention. All patients were followed up 6 to 24 months with an average of 12 months. The size and shape of the noses were stable, and no compli cation, such as cartilage exposure, hematoma, or infection occurred during the postoperative follow-up. There were 4 cases with obvious incision scars, 3 cases with nostril and alar asymmetry, and 1 case of lateral side of the nose without well positioned. The symmetry of the highest points of bilateral nostrils was 57.643%±27.491% before operation and 90.246%±18.769% after operation. The symmetry of the most lateral points of the bilateral nostrils was 77.391%±30.628% before operation and 92.373%±21.662% after operation. And there were significant differences between pre- and post-operation (P<0.05). There were also significant differences in the distance of highest point of the affected nostril to the X-line, the distance of the nostril’s outermost point to the Y-line, and the distance of the highest point of the nasal tip to the X-line (P<0.05). No thoracic contour change occurred at the costal cartilage donor site.ConclusionThe thin-ribbed cartilage with the perichondrium has good support and long-term stability, and it can be used as one of the ideal materials for nasal alar cartilage transplantation for nasal deformity secondary to cleft lip.
