Surgical resection of tumors in the maxillofacial region sometimes results in extended defects of soft and hard tissue that frequently causes aesthetic, functional and especially mental damages. It is essential for patients with such facial defects to reduce the scar and maxillofacial asymmetry. To attain esthetic facial appearance after hemimaxillectomy, we devise a new design, so called 'IOIO Incision' (InfraOrbital-IntraOral incision). The new approach is established on infraorbital region to expose maxillofacial skeleton in aspect of face. And the other incision is designed on intraoral region. The IOIO incision provide excellent aesthetic result after hemimaxillectomy, because of reduced minimal facial scar contraction. Maxillofacial surgeons are used to designing Weber-Fergusson incision in resection of maxillofacial tumors, but disadvantages of the incision were large scar and asymmetry of face. To improve theses problem, we attempted IOIO Incision.. For correct osteotomy of posterolateral wall of maxillary sinus, 1. Fenestra formation on zygomatic body for easily access of reciprocating saw to posterolateral wall of maxillary sinus. 2. To achieve better visual field in posterolateral aspect of maxilla, fat tissue is removed from infratemporal fossa. This new, versatile procedure can be used for benign and malignant lesions of the maxillary area. We introduce cases with review of literatures.

Vocal fold scarring is an intractable phonosurgical condition. The number of patients with vocal fold scars is increasing with the aging of society and with the increasing application of laryngeal microsurgery. Many methods are available to treat these, including voice therapy, stem cells, regenerative scaffolds, and growth factors. However, no standard treatment strategy has yet been established, and novel techniques are required. Basic fibroblast growth factor has been shown to be effective for the treatment of mild chronic vocal fold scarring. The combined use of basic fibroblast growth factor and regenerative scaffolds is currently under investigation. Here, we report a female patient in whom vocal fold scarring developed after two laryngeal microsurgeries. We performed laryngeal microsurgery to remove the scar tissue and used basic fibroblast growth factor and a collagen scaffold to promote healing. The patient's voice quality was greatly increased, and she was content with her voice after 2 years of follow-up. This is the first report of this methodology in Korea and is presented along with a review of the literature.

Purpose: Reconstruction of the cleft earlobe is challenging. Several procedures are available to reconstruct congenital earlobe deformities. However, for large defective type, surgical procedures and designs are complex and tend to leave a visible scar. We present a simple method of reconstruction for defective type congenital cleft earlobe using a one stage technique with infraauricular transposition flap. This allows for easy and accurate size estimation and good aesthetic outcomes. Methods: A 4-year-old male patient has congenital cleft earlobe and antihelical deformity. Otoplasty for antihelical deformity correction and one stage infra-auricular transposition flap for earlobe reconstruction were performed. The flap was designed from the inferoanterior margin of the earlobe. The size of the flap was determined based on the normal side, and the width and length of the flap was 1 cm and 3 cm in size, respectively. An incision was made at the midline of the defective lobule. Further, the elevated flap was inserted. The elevated flap and the incision margins of the lobule were sutured together. Then, the donor site was closed primarily. Results: The volume and shape of the reconstructed earlobe were natural. There was no flap necrosis. The donor site had no morbidities and scar was not easily notable. Conclusion: Infra-auricular transposition flap can be designed easily and offer sufficient volume of earlobe. Furthermore, the scar is inconspicuous. In conclusion, infra-auricular transposition flap can be a good option for reconstructing a large defect type cleft earlobe.

Purpose: The Inaba's procedure, the treatment of osmidrosis axillae, has the advantages of low recurrent rate and easy to learn, yet it produces early postoperative discomfort and scar formation by tie - over dressing. The authors modified the Inaba's procedure by using delayed suture of the incision wound and omitting tie - over dressing. The comparative study of Inaba's procedure and its modification was performed to confirm the advantages of modified procedure. Methods: The study contains the retrospective analysis of the medical records of 296 patients with osmidrosis who were treated using the Inaba's procedure from December, 1996 to February, 2007. The study also contains the prospective analysis of 20 patients, from March, 2007 to July, 2008, who were treated by the modified Inaba's procedure with delayed suture of the incision wound and gentle pressure dressing instead of tie - over dressing. The operative results of two groups were compared and verified by Mann - Whitney U test(SPSS 12.0). Results: The incidence of complications was 14.5% in the Inaba's procedure, whereas 6.2% in the modified Inaba's procedure. Both procedures have the same basic surgical procedure in terms of the location of incision site and subdermal shaving of the sweat glands, and therefore similar good results were obtained in the aspect of postoperative axillary odor, recurrent rate and postoperative condition of axillary hair. Certainly, the modified Inaba's procedure had better outcome in each element of PSS(Patient Scar Self-Rating Scale), compared to the Inaba's procedure. In addition, the modified Inaba's procedure showed a statistical significance in dressing - related pain reduction and overall satisfaction. Conclusion: The modified Inaba's procedure had advantages of decreased early postoperative complications such as hematoma, discomfort and pain caused by tie - over dressing, and decreased scar formation. However, the drawback was delayed suture of the incision wound after 48 hours.

Background: Full-thickness skin grafts (FTSGs) have been widely used after facial skin cancer resection, for correcting defects that are too wide to be reconstructed using a local flap or if structural deformation is expected. The preauricular, posterior auricular, supraclavicular, conchal bowl, nasolabial fold, and upper eyelid skin areas are known as the main donor sites for facial FTSG. Herein, we aimed to describe the effectiveness of using infraclavicular skin as the donor site for specific cases. Methods: We performed FTSG using the infraclavicular skin as the donor site in older Asian adults following skin cancer resection. Outcomes were observed for > 6 months postoperatively. The Manchester Scar Scale was used for an objective evaluation of satisfaction following surgery and scarring. Results: We analyzed the data of 17 patients. During follow-up, the donor and recipient sites of all patients healed without complications. Upon evaluation, the average Manchester Scar Scale scores for the recipient and donor sites were 7.4 points and 5.7 points, respectively. Conclusion: In general, conventional donor sites, such as the preauricular, posterior auricular, and supraclavicular sites, are widely used for facial FTSG because they achieve good cosmetic results. However, the infraclavicular skin may be a useful donor for facial FTSG in cases where the duration of time spent under anesthesia must be minimized due to a patient's advanced age or underlying health conditions, or when the recipient site is relatively thick area, such as the nose, forehead, or cheek.

Cesarean scar pregnancy (CSP) is a rare complication that occurs in less than 1% of ectopic pregnancies, and uterine didelphys is one of the rarest uterine forms. We report a successful laparoscopic excision and repair of CSP in a woman with uterine didelphys and a double vagina. A 34-year-old gravida one, para one woman with a history of low transverse cesarean section presented to our hospital with a suspected CSP. She was confirmed to have uterine didelphys with a double vagina during an infertility examination 7 years earlier. Magnetic resonance imaging showed a 2.5-cm gestational sac-like cystic lesion in the lower segment of the right uterus at the cesarean scar. We decided to perform a laparoscopic approach after informing the patient of the surgical procedure. The lower segment of the previous cesarean site was excised with monopolar diathermy to minimize bleeding. We identified the gestational sac in the lower segment of the right uterus, which was evacuated using spoon forceps. The myometrium and serosa of the uterus were sutured layer-by-layer using synthetic absorbable sutures. No remnant gestational tissue was visible on follow-up ultrasonography one month after the surgery. This laparoscopic approach to CSP in a woman with uterine didelphys is an effective and safe method of treatment. In women with uterine anomalies, it is important to confirm the exact location of the gestational sac by preoperative imaging for successful surgery.

In adult congenital muscular torticollis (CMT) patients, physical therapy is not as effective because the development of sternocleidomastoid muscle (SCM) muscle is complete. While surgical release can address CMT in adult patients, the risk of general anesthesia and visible postoperative scar is a concern, expecially in patients with mild symptoms. In this paper, we report our experience in treating such patients with minimal-incision myotomy under local anesthesia. A review was performed for all adult patients who had undergone the simple myotomy procedure. Surgical indication was reserved for patients with mild fibrotic band in the SCM muscle with minimal lengthdiscrepancybetween the muscles. All patients had recognizable head tiltand palpation of fibrotic band on affected side of the neck. Surgical details are described in the main body of text. Three female patients had undergone the procedure. Torticollis was resolve in all patients with complete restoration of ranage of motion. There were no postoperative complications, and patient satisfaction was high. We have reported three cases of mild CMT in adult female patients, who had undergone minimal-incision myotomy under local anesthesia. Outcomes were satisafactory with no morbidity to report. With careful patient selection, this method offers an alternate treatment option for adult CMT patients with mild symptoms.

Purpose: To review the surgical results of stiff elbow using the posterior extensile approach which provides a wide surgical view with a single posterior skin incision. Materials and Methods: From February 1999 to May 2002, we performed 6 surgical correction of stiff elbow using posterior extensile approach and followed the patients more than 1 year. In order to get better result, we performed cadaver study (four elbows of two fresh cadavers). Average duration of follow up was 15.7 months $(14{\sim}21)$. Functional results was analyzed using Brobery and Morrey analysis scale. Results: The approach through the plane between the extensor carpi radialis longus and the extensor carpi radialis brevis was ideal, because it preserves normal anatomy and provides a wide surgical view of the anterior joint. The posterior joint could be approached directly between the medial head of the triceps brachii and brachialis medially, the lateral head of triceps brachii and brachioradialis laterally. In all patients, an improved ROM was obtained with intra and extra-articular adhesiolysis: an average $61.7^{\circ}$ improvement $(50{\sim}75)$. Functional results were as follows: five excellent, one good. In addition, the patients' satisfaction was high since the scar from the operation was only a single line at the posterior surface of the elbow. Conclusion: In the treatment of stiff elbow, posterior extensile approach is thought to be useful because this method provides wide anterior and posterior surgical view.
