Congenital anomalies of the head and neck region such as preauricular sinus and skin tag, thyroglossal duct cyst, branchial anomaly, cystic hygroma and dermoid cyst are common in pediatric population. It is important for pediatricians and pediatric surgeons to be familiar with the embryology and the anatomical characteristic of these lesions in order to diagnose and treat them properly. Three hundred and nineteen patients with congenital head and neck anomalies treated at Hanyang University Hospital between 1980 and 1999 were reviewed to determine the relative frequency of the anomalies and to analyze the method of management. Eight-four (25.1 %) of 335 lesions were preauricular sinus and skin tag, 81 (24.2 %) were thyroglossal duct cyst, 81 (24.2 %) branchial anomaly, 58 (17.3 %) cystic hygroma and 31 were (9.2 %) dermoid cyst. The male-to-female ratio was 1.4:1. Thyroglossal duct cyst most commonly present at 3-5years, however branchial anomalies commonly are diagnosed in children younger than 1 year. Preauricular sinus showed familial tendency in three patients and was bilateral is 33.8 %. Most head and neck anomalies in children have specific clinical and anatomical characterics. A careful history and physical examination is very useful for diagnosis and proper management. Experienced pediatric surgeons should do the initial surgery since the recurrence rate after incomplete surgical excision can be high.

Purpose: To report a rare case of concealed penis that was aggravated by circumcision and simple way of treatment using skin flap. The concealed penis is a primarily pediatric disease and is usually treated by urologists. The plastic surgeons tend to see these patients when it become secondary deformation or in conjoinment with other specialties. In such situation, the plastic surgeons do not have many experiences. Methods: A 3-year-old boy was admitted with aggravated concealed penis after circumcision in congenital webbed penis. Patient had been operated with scar revision and skin flap and peri operative antibiotics. Results: The patient recovered well without any complication such as infection, hematoma and necrosis of flap. Patient was discharged POD#7 with remaining sutures. Patient was followed up for 7 months and he has no sign of erectile dysfunction, voiding dysfunction and evidence of inflammation of the urinary system. Conclusion: We experienced a case of concealed penis that was aggravated from aggressive circumcision in congenital webbed penis.

Facial rejuvenation procedures can be roughly divided into face lift surgery and nonoperative, less invasive procedures, such as fat grafts, fillers, botulinum toxin injections, thread lifts, or laserbrasion. Face lift surgery or rhytidectomy is the procedure most directly associated with rejuvenation, due to its fundamental ability to restore the anatomical changes caused by aging. Various methods of face lift surgery have been developed over the last hundred years, thanks to advances in the understanding of facial anatomy and the mechanisms of aging, as well as the dedication of innovative surgeons. However, no generally applicable standard method exists, because the condition of each patient is different, and each operative method has advantages and disadvantages. Specific characteristics of the skin of Asians and their skeletal anatomy should be considered when determining the operative method to be used on Asian patients. Plastic surgeons should improve their ability to analyze the original aesthetic properties and problem areas of each patient, drawing on scientific knowledge about the aging process, and they should develop the skills necessary to perform various rejuvenative techniques. In the present article, we reviewed various face lift procedures and the current methods of modified double plane face lift, based on our clinical experience of over 30 years.

Dupuytren's contracture is a condition commonly encountered by hand surgeons, although it is rare in the Asian population. Various surgical procedures for Dupuytren's contracture have been reported, and the outcomes vary according to the treatment modalities. We report the treatment results of segmental fasciectomies with multiple transverse incisions for patients with Dupuytren's contracture. The cases of seven patients who underwent multiple segmental fasciectomies with multiple transverse incisions for Dupuytren's contracture from 2006 to 2011 were reviewed retrospectively. Multiple transverse incisions to the severe contracture sites were performed initially, and additional incisions to the metacarpophalangeal (MCP) joints, and the proximal interphalangeal (PIP) joints were performed if necessary. Segmental fasciectomies by removing the fibromatous nodules or cords between the incision lines were performed and the wound margins were approximated. The mean range of motion of the involved MCP joints and PIP joints was fully recovered. During the follow-up periods, there was no evidence of recurrence or progression of disease. Multiple transverse incisions for Dupuytren's contracture are technically challenging, and require a high skill level of hand surgeons. However, we achieved excellent correction of contractures with no associated complications. Therefore, segmental fasciectomies with multiple transverse incisions can be a good treatment option for Dupuytren's contracture.

For implant treatment there must be sufficient bone to house the implant body. At least 5mm wide residual bone is needed and usually a 6mm width is preferred by clinicians. However, surgeons sometimes find patients with a narrow ridge, which makes it difficult to place an implant. Therefore, many clinicians perform bone graft or a ridge splitting technique to overcome these poor conditions. The time and cost can be reduced using the ridge splitting technique with immediate implant placement. Recently, many studies reported reliable consequences of ridge splitting technique. This paper reports a successful of implant placement with a ridge splitting technique in a very thin alveolar ridge.

Various surgical techniques, such as endoscopic surgery and robotic surgery, are developed to optimize the esthetic outcome even in operations for malignancy. A modified face-lift or retroauricular approach are used to minimize postoperative scarring. Recently, robot-assisted surgery is being done in various fields and considered as favorable treatment method by many surgeons. However its high cost is a nonnegligible fraction for many patients. On the other hand, endoscopic surgery, which is cheaper than robotic surgery, is minimally invasive with contentable neck dissection. Although it is a difficult technique for a beginner surgeon due to its limited operation view, we suppose it as an alternative method for robotic surgery. Herein, we report two cases of endoscopic neck dissection via retroauricular incision with a discussion regarding the pros and cons of endoscopic neck dissection.

Fractures of the orbital floor and walls are among the most frequent maxillofacial fractures. Virtual three-dimensional (3D) planning and use of patient-specific implants (PSIs) could improve anatomic and functional outcomes in orbital reconstruction surgery. The presented case was a victim of a terrorist attack involving improvised explosive devices. This 58-year-old female suffered severe wounds caused by a single piece of metal from a bomb, shattering the left orbital floor and lateral orbital wall. Due to remaining hypotropia of the left eye compared to the right eye, late orbital floor reconstruction was carried out with a personalised 3D printed titanium implant. We concluded that this technique with PSI appears to be a viable method to correct complex orbital floor defects. Our research group noted good aesthetic and functional results one year after surgery. Due to the complexity of the surgery for a major bony defect of the orbital floor, it is important that the surgery be executed by experienced surgeons in the field of maxillofacial traumatology.

Alveolar soft-part sarcoma(ASPS) is a rare, aggressive malignancy of uncertain histologic origin with a propensity for vascular invasion and distant metastasis. ASPS may mimic benign vascular neoplams of malformation but careful evaluation of the unique imaging features on CT scans, MR images, and angiograms lead to the correct diagnosis. ASPS of the tongue is slow-growing, painless mass, especially ASPS of the base the tongue is difficult to be noticed by patient, dentists or oral and maxillofacial surgeons on oral examintion because of its location and clinical resemblance to a benign lesion. And it leads to delayed or inadequate diagnosis. We report radiologic and clinical features of an ASPS of the basal portion of the tongue in a 17-year-old boy, showing normal appearance, but palpation of the tongue and floor of the mouth reveals the tumor. Among the 23 cases of a primary ASPS of tongue reported, 7 cases occured on the basal region of the tongue, inculding the present one. There has been no recurrence or metastasis as of 3 years postoperatively.

This nationwide survey was conducted to evaluate the current status of clinical practice for gastric cancer patients in Korea. The Information Committee of the Korean Gastric Cancer Association (KGCA) sent questionnaires containing 45 items about the preoperative diagnosis, medical and surgical treatment, and postoperative follow-up for gastric cancer patients to all 298 KGCA members in 108 institutes. Response rates were $32.6\%$ (97/298) for individuals and $59.3\%$ (64/108) for institutes. Most university hospitals responded (response rate of university hospitals: $71.6\%$, 48/67). The preoperative staging work up was performed primarily by abdominal CT, followed by bone scans, abdominal ultrasound, endoscopic ultrasound, and so on. Gastric cancer patients with stages II, III, and IV usually received adjuvant chemotherapy after a curative operation. About half of the surgeons regarded 2 cm as a safe resection margin in early gastric cancer and 5 cm in advanced gastric cancer. More than half of surgeons usually performed a D2 lymph node dissection in early gastric cancer and D2+$\alpha$ lymph node dissection in advanced gastric cancer. About $20\%$ of surgeons performed less invasive surgery and/or function-preserving surgery, such as a pylorus-preserving gastrectomy, a laparoscopic wedge resection, or a laparoscopy-assisted distal gastrectomy.
