Soft-tissue osteoma of the temple
Roh, Si-Gyun,Kim, Yun-Seob,Kim, Jong-Lim,Shin, Jin-Yong,Lee, Nae-Ho Korean Cleft Palate-Craniofacial Association 2021 Archives of Craniofacial Surgery Vol.22 No.5
A 65-year-old woman presented with a solid mass on the right temporal area. The mass had grown for over 2 years without any initiating event of trauma or inflammation. Before excision, the patient went through a computed tomography scan, revealing a calcified mass without bony connection. Under general anesthesia, an excisional biopsy was performed. Microscopic examination confirmed a diagnosis of soft tissue osteoma. Soft tissue osteoma is rare, especially in the head and neck region. Osteomas in the temporal region have not been reported yet. Due to its rarity, osteoma might be misdiagnosed as another soft tissue or bone origin tumor. Its treatment of choice is simple excision. In this review, we present an unusual clinical form of soft tissue osteoma.
Reconstruction of the sciatic nerve using bilateral vascularized sural nerve grafts: a case report
Si-Gyun Roh,천재영,이내호,신진용,김종림 대한수부외과학회 2022 대한수부외과학회지 Vol.27 No.1
An injury of a peripheral nerve may require reconstruction for motor and sensory function recovery. However, if the nerve defect is long, especially in the lower extremities, reconstruction with successful functional recovery has proven to be difficult. We documented a case of bilateral vascularized sural nerve graft repair of a large and long sciatic nerve defect following malignant tumor resection on the posterior thigh. Although we were unable to achieve satisfactory outcomes in motor function recovery, we did achieve some degree of sensory function recovery.

Background: Plastic and reconstructive surgeons consider a variety of options to salvage limbs of patients when operating on soft tissue defects of the plantar forefoot in diabetic foot ulcers. This study focuses on the efficacy and durability of perforator flaps compared to that of random flaps, when covering the plantar forefoot area in diabetic patients. Methods: From January 2011 to August 2020, we performed 49 plantar forefoot reconstructions to cover soft tissue defects in diabetes patients using local random flaps, regional perforator-based flaps, or free flaps. The patients’ clinical characteristics, size of defects, surgical outcomes and complications were reviewed retrospectively. Results: Forty-nine patients underwent plantar forefoot reconstruction over the period reviewed. Eleven patients were female and the others were male. The mean age of the patients was 54.2 years (range, 32–73 years). Median follow-up was 5.2 months. The mean size of the defect was 7.2×4.5 cm. During follow-up periods, partial or complete loss of flaps was closely observed. We identified wound complications in 67% of local random flaps compared to 11% and 21% in regional and free flaps, respectively. Conclusion: Soft tissue defects in the distal third of the foot can severely worsen diabetic patients’ quality of life. Perforator-based flaps, providing better vascularized tissue than random flaps, can be used to attain acceptable functional and aesthetic results for plantar forefoot reconstruction in diabetes patients.

The reconstruction of total lower eyelid defects is challenging to plastic surgeons due to the complicated anatomical structure of the eyelid. In addition, in the setting of cancer excision, the resection is deep, which requires some volume augmentation. However, in some cases,free tissue transfer is not applicable. We report a case of using a temporoparietal fascia flap (TPFF) for reconstructing a total lower eyeliddefect. A large erythematous mass in an 83-year-old woman was diagnosed as squamous cell carcinoma by biopsy. After wide excision,the defect size was about 8× 6 cm. The lower eyelid structures including the tarsus were removed. The TPFF including the superficial temporal artery was elevated and inset to the defect area. After the flap inset, a split-thickness skin graft with an acellular dermal matrix wasperformed on the fascial flap. There were no wound problems such as infection, dehiscence, or necrosis. After the patient’s discharge, partial skin graft loss and ectropion occurred. The complications resolved spontaneously during the postoperative period. We report a case ofreconstructing a lower eyelid defect using a TPFF. A TPFF can be applied to patients with large defects for whom free tissue transfer surgery is not appropriate as in this case.
Tubed-Groin Flap for Coverage of Deep Burn Injuries in Two Adjacent Fingers: A Case Report
천재영,Lee Nae-Ho,Roh Si-Gyun,Shin Jin Yong 대한창상학회 2022 Journal of Wound Management and Research Vol.18 No.2
The reconstruction of two adjacent fingers is challenging for reconstructive surgeons, especially if there is a circumferential skin and soft-tissue loss along with bone exposure. Herein, we present the case of a 22-year-old male with a circumferential defect in two adjacent fingers due to an electrical burn. The patient had a circumferential soft-tissue defect with middle phalangeal bone exposure in the left index and middle fingers, revealed after serial debridement and ostectomy. After failure of free flap reconstruction, other options were considered, and the defects were repaired using a newly designed tubed-groin flap. Afterwards, flap detachment was performed on postoperative day 21 and provisional syndactyly separation without a skin graft was performed 2 weeks after flap detachment surgery. The patient was satisfied with the well-reconstructed fingers, which demonstrated adequate length and function. A full range of motion of the metacarpophalangeal joint was restored. The newly designed tubed-groin flap can be an efficient method to easily and effectively reconstruct a circumferential defect in two adjacent fingers.

Background A recent advancement in microsurgery, the free flap is widely used in the reconstruction of the lower leg and foot. The simple and effective methods of local flaps, including transposition and advancement flaps, have been considered for patients with chronic debilitation who are unable to endure long surgical procedures or general anesthesia. However, the location and size of the wound may restrict the clinical application of a local flap. Under these circumstances, a sural flap can be an excellent alternative, rendering satisfying clinical outcomes in chronically debilitated patients. Methods Between 2008 and 2012, 39 patients underwent soft tissue defect treatment by sural artery flap as a final method. All of the patients had at least one chronic disease or more (diabetes, hypertension, vascular disease, etc.). Also, all of the patients had a history of chronic lower extremity ulceration, which revealed no response to several months of conservative treatment. Results The results of the 39 cases had a success rate of 100% with 39 complete recoveries. Nine cases suffered complications: partial necrosis (n=4), wound dehiscence without necrosis (n=3), hematoma (n=1), and infection (n=1). Conclusions The sural artery flap is not only useful for the lower leg but also for the heel, and other various parts. Furthermore, it is a relatively simple surgical technique for reconstructing the defect area for patients with various chronic conditions with a high surgical risk or contraindications to surgery.

Yonsei Dermatology celebrated its centennial in 2017, marking 100 years since Kung Sun Oh established the first Department of Dermatology and Urology in Korea in 1917. Following the footsteps of Kung Sun Oh, a pioneer of Korean dermatology, its members united and worked to provide the best medical service and achieve academic milestones in dermatology. Over the past hundred years, Yonsei Dermatology has played a pivotal role in the advancement of medical science and academia in Korea. The main activities of the department include medical care, education, and dermatologic research. Its research activities have encompassed a wide spectrum of dermatologic manifestations from skin immunology and pathology to introduction of newly developed treatment technologies. As Kung Sun Oh was the first Korean professor of dermatology at Severance Medical School and a passionate educator, we continue to serve his will by nurturing medical students and dermatology special-ists to serve as global medical leaders. The Kung Sun Oh Memorial Lecture, first hosted in 1977, was the beginning of mutual international academic exchange in the field of dermatology in Korea. The memorial lecture has played a major role in advancing the academic status of Korean dermatological science by inviting distinguished dermatologists from around the world as guest lecturers. Yonsei Dermatology has played a key role in the history of modern medicine and dermatology in Korea over the last 100 years and continues to make an impact. (Ann Dermatol 30(5) 513∼521, 2018)
