Diabetic foot ulcer is a serious complication which result from long-standing diabetes. Especially, severe infected diabetic foot ulcer results in unwanted lower extremity amputation. The diabetic patient is considered the relative contraindication for microsurgery because of the severe peripheral vascular disease. Recently, microvascular free tissue transfer technique applied to diabetic foot ulcer. It is well known that free tissue transfer provides immediate soft tissue coverage and control of infection. So it is possible that preservation of the lower extremity through free tissue transfer. A retrospective study of diabetic patients who had infected foot ulcer from 1999 to 2000 with foot defects reconstructed with free tissue transfer were reviewed. Thirteen patients were studied with mean follow-up of 12.7 months. There were two deaths during follow-up period. There were two failures after free flap surgery. All eleven survived patients were ambulatory. There was no recurrence of ulcer. No patient need amputation above the ankle joint. We have found that free tissue transfer for infected diabetic foot ulcer is very effective surgical technique. Careful patient selection and regular follow-up is important.

Background: Prolonged air leak is a common complication after thoracoscopic bullectomy. Materials and methods: A technique is described to minimize postoperative air leak in thoracoscopic surgery for the treatment of recurrent or persistent spontaneous pneumothorax. Results: A 3.5cm utility incision is made in the anterior axillary line at the level of the third intercostal space, and blebs and bullae are stapled and sutured without excision, using standard surgical instruments and stapler. Conclusions: This technique may be useful to reduce prolonged air leak after removal of the bleb and bullous lesion, and may minimize the delayed recurrence of ipsilateral pneumothorax.

Arthroscopic treatment has been reported to provide effective improvement of ankle function when used in treatment of small osteochondral lesion of talus; however, favorable long-term results have been less predictable for large osteochondral lesion of talus. In cases in which primary arthroscopic treatment fails, the decision regarding which subsequent technique to choose has become increasingly difficult, as good clinical outcomes may be unlikely for such patients irrespective of the surgical technique used. Redomicrofracture should be used judiciously for treatment of osteochondral lesion of talus in which arthroscopic treatment has failed.

The two major concerns in skin grafting are poor color match at the recipient site and donor site morbidity. To overcome the limitations of the classic skin graft, we have used dermis graft-deepithelialized split thickness skin graft-for coverage of small to medium sized wounds. The important aspects of this methods involve the immediate return of epidermis to the donor site to overcome donor site morbidity and restoration of the epidermis at the recipient site by neo epithelization from the adjacent skin. From April of 2001 to July of 2003, the dermis graft was applied to 32 patients. Simultaneously, the regular split thickness skin graft procedure was performed in 33 patients. We compared the healing time in all patients. The scar condition was also evaluated at 2 to 12 months after operation. The entire dermis grafts were reepithelialized in 15.5 days. The skin grafted wounds were healed by 11.8 days. Regarding the donor sites, donor sites of dermis graft healed within 7.5 days. On the contrary those of regular skin graft required 12.8 days. The donor sites of the dermis graft were also superior to those of skin graft in scar quality and patient satisfaction. The dermis graft technique for wound coverage compares favorably to regular skin graft technique in both recipient and donor sites aesthetically and functionally.

Background: The presence of septa increases the risk of Schneiderian membrane perforation during sinus lift procedure, and therefore, the chance of graft failure increases. We present a safe method of managing septa and, in particular, overcoming small and palatally located septa. Methods: After the elevation of the flap and the creation of a small bony window positioned anterior to the septum, the Schneiderian membrane is lifted carefully. A thin and narrow osteotome is then placed at the indentation created at the base of the septum, and mobilization of the septum is achieved by gentle malleting. The membrane is again carefully lifted up behind the septum. Results: There was one small membrane perforation case in all 16 cases, and none of these patients showed postoperative complications such as implant failure, infection, or maxillary sinusitis. Conclusions: This technique is useful for overcoming the problem of maxillary sinus septa hindering the sinus floor elevation procedure, leading to fewer complications.

Three-dimensional (3D) computed tomography image models are helpful in reproducing the maxillofacial area; however, they do not necessarily provide an accurate representation of dental occlusion and the state of the teeth. Recent efforts have focused on improvement of dental imaging by replacement of computed tomography with other detailed digital images. Unfortunately, despite the advantages of medical simulation software in dentofacial analysis, diagnosis, and surgical simulation, it lacks adequate registration tools. Following up on our previous report on orthognathic simulation surgery using computer-aided design/computer-aided manufacturing (CAD/CAM) software, we recently used the registration functions of a CAD/CAM platform in conjunction with surgical simulation software. Therefore, we would like to introduce a new technique, which involves use of the registration functions of CAD/CAM software followed by transfer of the images into medical simulation software. This technique may be applicable when using various registration function tools from different software platforms.

A 19-year-old woman presented to our dental clinic with anterior crossbite and mandibular prognathism. She had a concave profile, long face, and Angle Class III molar relationship. She showed disharmony in the crowding of the maxillomandibular dentition and midline deviation. The diagnosis and treatment plan were established by a three-dimensional (3D) virtual setup and 3D surgical simulation, and a surgical wafer was produced using the stereolithography technique. No presurgical orthodontic treatment was performed. Using the surgery-first approach, Le Fort I maxillary osteotomy and mandibular bilateral intraoral vertical ramus osteotomy setback were carried out. Treatment was completed with postorthodontic treatment. Thus, symmetrical and balanced facial soft tissue and facial form as well as stabilized and well-balanced occlusion were achieved.

Nipple-areolar complex (NAC) reconstruction is the final step in the long journey of breast reconstruction for mastectomy patients. Successful NAC reconstruction depends on the use of appropriate surgical techniques that are simple and reliable. To date, numerous techniques have been used for nipple reconstruction, including contralateral nipple sharing and various local flaps. Recently, it has been common to utilize local flaps. However, the most common nipple reconstruction problem encountered with local flaps is the loss of nipple projection; there can be approximately 50% projection loss in reconstructed nipples over long-term follow-up. Several factors might contribute to nipple projection loss, and we tried to overcome these factors by performing nipple reconstructions using a boomerang flap technique, which is a modified C-V flap that utilizes the previous mastectomy scar to maintain long-term nipple projection.

Background Descent of the lateral aspect of the brow is one of the earliest signs of aging. The purpose of this study was to describe an open surgical technique for lateral brow lifts, with the goal of achieving reliable, predictable, and long-lasting results. Methods An incision was made behind and parallel to the temporal hairline, and then extended deeper through the temporoparietal fascia to the level of the deep temporal fascia. Dissection was continued anteriorly on the surface of the deep temporal fascia and subperiosteally beyond the temporal crest, to the level of the superolateral orbital rim. Fixation of the lateral brow and tightening of the orbicularis oculi muscle was achieved with the placement of sutures that secured the tissue directly to the galea aponeurotica on the lateral aspect of the incision. An additional fixation was made between the temporoparietal fascia and the deep temporal fascia, as well as between the temporoparietal fascia and the galea aponeurotica. The excess skin in the temporal area was excised and the incision was closed. Results A total of 519 patients were included in the study. Satisfactory lateral brow elevation was obtained in most of the patients (94.41%). The following complications were observed: total relapse (n=8), partial relapse (n=21), neurapraxia of the frontal branch of the facial nerve (n=5), and limited alopecia in the temporal incision (n=9). Conclusions We consider this approach to be a safe and effective procedure, with long-lasting results.
