Binder's syndrome has some characteristic signs, such as orbital hypotelorism, shortened and flat noses, diminutive columella, crescent shaped nostrils, acute nasolabial angle, convex upper lip, class III malocclusion, absent anterior nasal spine, and maxillary hypoplasia. Binder's syndrome patients usually need the correction of the following three: the hypoplatic nose, the perialar flatness due to underdevelopment of the piriform margin, and the hypoplastic maxilla with its malocclusion. The authors treated eleven(n=14) patients through various surgical techniques depending on the clinical signs. In order to correct the nasomaxillary hypoplasia, the autogenous bones, the autogenous cartilages and the alloplastic implants were used. In three patients with severe nasomaxillary retrusion, the combined Le Fort I and II osteotomies and the perinasal osteotomy were performed. The results were analyzed using the proportion indices from the preoperative and postoperative lateral photographs of the patients. The postoperative values of all the proportion indices were significantly higher compared to the preoperative ones. For nasal dorsal augmentation, columellar lengthening and peripiriform augmentation, autogenous bone grafts were found to be very effective. The use of high-density porous polyethylene sheets for columellar lengthening was preferred over the use of nasal septal cartilages. Two types of osteotomy were the most effective for nasomaxillary augmentation in severe deformity.

For decades, many surgical techniques have been devised for correction of the gummy smile including mucosal resection, myectomy, the implant spacer technique, and osseous shortening of the alveolar-maxillary complex in case of vertical maxillary excess. However there are several problems in those techniques: the mucosal resection and the myectomy tends to recur, there would be the morbidity of the implant in the implant spacer technique, and the osseous shortening of the alveolar-maxillary complex is a procedure for the long face syndrome. Our technique is freeing the levator labii suprioris muscles and cinching them to the anteroinferior nasal septal cartilage for loss of muscle action. Seventeen patients(14 females and 3 males; mean age, 24 years) underwent operations. Preoperative photogrammetric analysis indicated the range of gum exposure when smiling was 2.0-9.0mm(mean, 3.8mm) and the maxillary lip length in repose was 17.0-29.0mm(mean, 23.1mm). Three to 31 months(mean, 12 months) after the operation, the results were analysed using the Wilcoxon signed ranks test. The postoperative gum exposure was ranged 0.0-4.0mm(mean, 0.4mm) (-3.4mm, p<0.05). And the maxillary lip length was elongated about 4%(+1.0 mm, p<0.05). Results were also analyzed clinically by the ordinary scale method. The gum exposure when smiling was excellent and the nature of the smile was good. Upper lip stiffness developed in all patients, but resolved completely within 1 month after the operatio. Hypesthesia of the upper lip was noted in 8 cases, but also disappeared within 2 months. Additionally, this technique resulted in narrowing of the interalar distance. Our technique is effective in correcting a gummy smile, but would not be recommended for patients with an abnormally narrow interalar distance.

Hemifacial microsomia is a condition most frequently associated with facial asymmetry. Authors have experienced eighteen patients with mild hemifacial microsomia who were classified as type IA and IB. For the correction of mandibular asymmetry, mandibular augmentation was performed on the mandibular angle of the affected side using mandibule shaped porous high-density polyethylene(Medpor) in thirteen patients. Reduction mandibuloplasty was performed on the mandibular angle of the normal side using lateral cortectomy in four patients, and genioplasties were used in 2 patients. Osseous genioplasty(n=10), buccal fat removal(n=4), augmentation rhinoplasty(n=2), and onlay bone graft(n=1) as ancillary procedures were simultaneously executed. Except for 4 patients in whom the implants were removed due to exposure and infection, all other patients were satisfied with a more symmetric contour of their face. The results were clinically evaluated through ordinary scale method and photogrammetric analysis. The mean score was rated 'good' as 12.5 points, and the mean bigonial distance index and the mean gonion-midsagittal distance index were 105.20%(p=0.035) and 100.65%(p=0.368), respectively, which meant a more symmetry of the lower face. In minor asymmetry of the mandible in cases of hemifacial microsomia, augmentation with cautions of the affected side, reduction with lateral cortectomy of the mandible in the non-affected side, and an even osseous genioplasty can provide the patient with a more symmetric lower face.

Purpose: In the treatment of the unilateral cleft lip nasal deformities, the correction of the low-nostril height and short-columella are very difficult problems. We report the treatment outcomes of web uni-limb Z-plasty used for correction of unilateral cleft lip nasal deformities by using photographic analysis. Methods: A total of 36 patients with unilateral cleft lip nasal deformities were enrolled in this study, who underwent web uni-limb Z-plasty and were followed up for at least 6 months. First, a triangular flap was made on the medial side of alar-columella web. The nostril apex of cleft side was corrected to a higher point compared to noncleft side by 2 mm. The flap was transposed into the defect of the vestibule. To reduce the bulging of the flap, horizontal cinching sutures were added. Postoperative outcomes were evaluated by using photographic analysis. 2 indices and 1 angle were measured on their photographs taken before and after the surgery. Symmetry was also evaluated by means of the noncleft side to cleft side index. For anthropologic assessment, observers described postoperative outcomes, using Ordinary Scale Method. Results: The postoperative values obtained in photographic analysis improved compared to preoperative ones. More improving anthropologic assessment was shown in post-than pre-operative.Conclusion: Although, further long term follow up is needed, we found this technique to be an effective procedure to the symmetry of nostril apex level and the lengthening of columella in the unilateral cleft lip nasal deformities.

In cryptotia the upper part of the auricle is buried beneath the temporal scalp, so the upper auriculocephalic sulcus is absent and auricular cartilage deformity is accompanied. The goals of surgical correction of cryptotia are to release the upper ear from temporal scalp to restore auriculocephalic sulcus, and to correct the cartilage deformity. Authors have experienced 23 auricles in 14 patients with cryptotia to correct cryptotia using lotus flower shaped V-Y advancement flap for the upper auricular skin deficiency and scoring for cartilage deformity. Lotus flower shaped flap is designed above superior pole of auricle. Designed flap has wider lower third than conventional V-Y flap. After complete exposure of upper auricular cartilage, cartilage deformity is corrected by scorings on lateral surface of the scapha and medial surface of the superior crus of antihelix. For construction of auriculocephalic sulcus, the flap is advanced inferiorly about 1cm and 3 stab incisions on the flap are made at the expected auriculocephalic sulcus. The cinch suture is done between dermal layer of the stab incisions and auriculocephalic sulcus cartilage with 4-0 Prolene??. Packing gauze is tied at corrected scapha for contour maintenance. A satisfactory contour of scapha and antihelical crus and deep auriculocephalic sulcus were maintained postoperatively. However, hypertrophic scar formation was found due to tension. Our method is similar to Ono's method in triangular flap shape. But the lotus flower shaped flap has wider lower 1/3 than Ono's triangular flap and provides sufficient skin for formation of auriculocephalic sulcus without additional rhomboid flap elevation in front of the ear.

Purpose: Complete septal extension grafts have been widely used in rhinoplasty for effective projection of the short retruded columella in Asian patients. Autologous septal cartilages and porous high-density polyethylene sheets are frequently used as septal extension grafts. This study was conducted to compare the postoperative results of porous polyethylene sheets and septal cartilages used for correction of unilateral cleft lip nasal deformities by using photogrammetric analysis. Methods: This study investigated a total of 49 patients with cleft lip nasal deformities who underwent corrective surgery, and were followed up for at least 6 months. Septal cartilages were used in 39 patients, and porous polyethylene sheets were used in 10 patients. In all patients, through the open rhinoplasty, complete septal extension grafts were sutured to the caudal margin of the septal cartilage, and the alar cartilage was sutured with suspension. The cleft side alar cartilage was overcorrected by approximately 3 - 5 mm. Postoperative outcomes were evaluated by using photogrammetric analysis. Five indices and 4 angles were measured on their photographs taken before and after the surgery. In patients with unilateral cleft lip nasal deformities, symmetry was also evaluated by means of columellar length index. Results: The postoperative values obtained in photogrammetric analysis showed improvements in comparison with the preoperative ones. The polyethylene group produced more improved outcomes than the septal cartilage group but also resulted in more complications at the same time. Conclusion: The results of this study indicates that complete septal extension grafts are efficient for the correction of unilateral cleft lip nasal deformities. However, since postoperative complications occur more frequently in the polyethylene group than in the septal cartilage group, caution is advised in using porous high-density polyethylene sheets in patients with cleft lip nasal deformities.

Purpose: In Korean rhinoplasty, alloplasts such as silicone rubber have been used for dorsal and tip augmentations. However, alloplasts have produced complications such as deviation, exposure, and infection. Although autogenous tissue is an ideal material, the amount of the cartilage in Korean is not sufficient. Therefore, the authors developed a method to harvest the maximum amount of the septal and conchal cartilage. The authors first performed a complete septal extension graft for short and retruded columella and then performed nasal augmentation using various autogenous tissues. Methods: These surgical techniques were performed on 11 patients. Their average age was 27 years. An open approach with a V-shaped columellar labial incision was performed. At first, the complete septal extension graft was fixed on the entire caudal margin of the septum, and the alar cartilage was suspended to the septal extension graft to make the tip projected and the columella advanced caudally. A temporal fascial ball was used for radix augmentation. For dorsal augmentation, a batten-shaped septal cartilage graft wrapped with or without the temporal fascia or a diced cartilage graft wrapped with the temporal fascia was performed. For nasal tip augmentation, a shield graft and a cap graft or a folded conchal cartilage graft was performed.Results: The mean follow-up period was 11.2 months. The overall results were natural and satisfactory. Two patients underwent slight absorption and caudal displacement. With the exception of these cases, no complications were observed. Conclusion: Korean rhinoplastic surgeons are accustomed to using the alloplasts despite of serious complications. When rhinoplasty using autogenous tissue was performed, some complications occurred such as the displacement of the diced cartilage graft wrapped with the fascia, but many of the complications of alloplastic rhinoplasty were avoided. Therefore, we propose that by this time Korean rhinoplastic surgeons need to change their preference from alloplastic rhinoplasty to autogenous rhinoplasty.
