Reconstruction of a full-thickness alar defect requires independent blood supplies to the inner and outer surfaces. Because of this, secondary operations are commonly needed for the division of skin flap from its origin. Here, we report a single-stage reconstruction of full-thickness alar defect, which was made possible by the use of a nasolabial island flap and septal mucosal hinge flap. A 49-year-old female had presented with a squamous cell carcinoma of the right ala which was invading through the mucosa. The lesion was excised with a 5-mm free margin through the full-thickness of ala. The lining and cartilage was restored using a septal mucosa hinge flap and a conchal cartilage from the ipsilateral ear. The superficial surface was covered with a nasolabial island flap based on a perforator from the angular artery. The three separate tissue layers were reconstructed as a single subunit, and no secondary operations were necessary. Single-stage reconstruction of the alar subunit was made possible by the use of a nasolabial island flap and septal mucosal hinge flap. Further studies are needed to compare long-term outcomes following single-stage and multi-stage reconstructions.

Oblique facial cleft is extremely rare. The frequency was reported 1/1300 cases of facial cleft. The cleft appears to be bilateral in approximately 20% and more often on the right when unilateral. Oblique facial cleft is nearly always associated with cleft lip and palate. Thus, the case that is unilateral on the left and not associated with cleft lip or palate is very rare. We experienced a case of 2 years 6 months old Philippine girl who had oblique facial cleft that is not associated with cleft lip or palate. The probable cause and treatment is discussed with a review of literatures.

Poly(g-glutamic acid) (g-PGA) is a very promising biodegradable polymer that is produced by microorganism of Bacillus subtilis. Because g-PGA is water-soluble, anionic, biodegradable, and even edible, its potential applications have been studied from an industrial standpoint. In this study, we fabricated porous g-PGA foams by means of a freeze-solvent extraction method for tissue-engineering applications. Porous g-PGA foams were chemically cross-linked using a hexamethylene diisocyanate solution. An aqueous basic solution was used to neutralize g-PGA foam for cell culturing. During an in vitro cell culture study, it was observed that primary rabbit ear chondrocytes were well at tached and spread over the surface oft hree-dimensional cross-linkedg-PGA foam. From these results, it is concluded that cross-linkedg-PGA foam is aprom is in gmaterial for tissue-engineering applications, especially those pertaining to the regeneration of human cartilage.

The human nose is located in the center of the face and it's cosmetic importance is high. The contour of the nasal dorsum and side walls play a major role in the shaping of the nose, and even a slight distortion may results in significant variance of the human facies. However, in the case of patients with wide nasal bone, augmention rhinoplasty can make nasal planes look wide, resulting in bulbous appearing noses or lateral borders of the nasal implant may be visible after the surgery making the final cosmetic results unsatisfactory. To solve such problems, from march, 1999 to march, 2004, the authors have performed augmention rhinoplasty in 36 patients. The cause of operations were as follows: flat nose 20, hump nose 5, deviated nose 4, secondary rhinoplasty 7. Paramedian osteotomy was performed at a distance that was the same as the width of the implant from the midline(5 mm + 5 mm). To prevent it from connecting to the roof at the lateral osteotomy line, intentional green stick fracture of the roof was performed. Agumentation rhinoplasty was done with either Silicone or Gortex and ear cartilage as a supplement. The follow up period was 2 weeks to 13 months with an average of 5.5 months. There were no infections and postoperative bleeding. As a result, the nose was augmented higher and narrower than before which we and the patient both found highly satisfactory.

Auricular endochondral pseudocyst is a very rare, benign intracartilaginous cystic lesion which most commonly presents as a cystic mass in the anterior plane of the auricle. We present a case report of a 48-year-old man with a fluctuating lesion of 3 week's duration on the left auricle, with no specific history of trauma or disease. Initial incisional drainage revealed an abundance of serous fluid, which quickly recurred. Surgical removal of the hypertrophic perichondrium forming the pseudocyst anterior wall and ear cartilage curettage was carried out with intraoperative absolute alcohol sclerotherapy, followed by compression dressings. The auricle healed uneventfully, with a good final cosmetic result and no recurrence within a 6-month follow-up period. We report this unusual case as the first in Korean plastic surgery with a review of the literature.

The columella, nasal tip, lip relationship in the secondary bilateral cleft deformity remains an enigma and a great challenge for the cleft surgeon. A subset of patients with bilateral cleft lip still require columellar lengthening and nasal correction, despite the advances in preoperative orthopedics and primary nasal corrections. An approach to correct this deformity is described. This consists of 1) lengthening the columella, 2) open rhinoplasty, allowing definitive repositioning of lower lateral cartilages, ear cartilage grafting to the tip and columella when necessary, 3) nasal mucosal advancement, 4) alar base narrowing and 5) reconstruction of the orbicularis oris as required. In surgical repair of the cleft lip nose, the timing of the operation(during lip closure, before or after the puberty growth sput), and the operative technique play a key role in the final result. In this study, 13 cleft lip patients who had undergone a secondary cheilorhinoplasty at the Department of Oral and Maxillofacial Surgery, Pusan National University Hospital were evaluated to check the proper time and method of the operation.

Background: Preauricular sinus (PAS) is a common congenital anomaly, and complete excision is recommended to prevent recurrence. However, PAS has a high recurrence rate as a result of incomplete removal due to the high variability of the sinus ramifications, making its treatment challenging. In this study, we standardized the surgical procedure to reduce the complications and recurrence rate and compared the postoperative results between the non-standardized and the standardized groups. Methods: This retrospective study included 97 patients (120 ears) who had undergone PAS excision by a single surgeon between October 2014 and September 2022 and underwent at least 6 months of follow-up. After October 2018, all patients were treated using the standardized method, which comprised the use of magnifying glasses, exploration with a lacrimal probe, the use of methylene blue staining, and excision of a piece of surrounding normal tissue and related cartilage in continuity with the specimen. There were 38 patients (45 ears) in the non-standardized group and 59 patients (75 ears) in the standardized group. Results: Recurrence was observed in six of 120 ears, indicating an overall recurrence rate of 5.0%. Recurrence occurred in five ears (11.1%) in the non-standardized group and one ear (1.3%) in the standardized group. The standardized group had a significantly lower recurrence rate (p= 0.027) than the non-standardized group. Conclusion: We defined a standardized sinectomy protocol and used it for the surgical treatment of PAS. With this standardized method, we were able to reduce the rates of complications and recurrence without the use of a long incision.
