Jae Doo Joo, Dong Hee Kang, Hyon Surk Kim
Background: Orbital resorbable mesh plates are adequate to use for isolated floor and medial wall fractures with an intact bony buttress, but are not recommended to use for large orbital wall fractures that need load bearing support. The author previously reported an orbital wall restoring surgery that restored the orbital floor to its prior position through the transnasal approach and maintained temporary extraorbital support with a balloon in the maxillary sinus. Extraorbital support could reduce the load applied on the orbital implants in orbital wall restoring surgery and the use of resorbable implants was considered appropriate for the author's orbital wall restoring technique...

Linear scleroderma en coup de sabre (LScs) is a variant of localized scleroderma. This disease typically occurs in patients in their 20s or younger individuals and predominantly occurs in the forehead area. A 26-year-old man with linear scleroderma was surgically treated at our center with Medpor (porous polyethylene) and dermal fat graft for the forehead lesion. After 26 months of postoperative follow-up, the depressed lesion that appeared scarred as well as the margins improved significantly. The surgical treatment of LScs using Medpor and dermal fat graft is an effective treatment modality that can increase patient satisfaction...

Intraoperative expansion has been used to cover small to large defects without disadvantages of the conventional tissue expanders. Various materials, for example, expanders and Foley catheters are being used. We introduce a new, convenient and economical device immediately available in the operating room, according to the defect size for intraoperative expansion, with latex gloves or balloons. The retrospective study was done with 20 patients who presented with skin and soft tissue defects. During the operation, expansion was done with latex gloves or balloons inflated with saline through an intravenous line and a three-way stopcock...

A schwannoma is a benign tumor that develops from Schwann cells. It is known to occur more frequently in women than men, and about one third of schwannoma cases occur in the head and neck area. It is also known to originate mainly in the auditory nerve. However, it is rarely associated with the trigeminal nerve, and especially, schwannomas related to the infraorbital nerve are very rare. we report a rare case of a schwannoma involving the infraorbital branch of the trigeminal nerve in a 45-year old male adult...

A 70-year-old male with a history of diabetes mellitus, hypertension, and coronary stent insertion visited our hospital 7 days after biting his lower lip. Swelling and inflammation had worsened despite debridement and antibiotic treatment. On the 8th hospital day, fungal infection with Candida albicans and superimposed bacterial infection with Klebsiella pneumoniae were found on tissue culture. Extensive necrosis resulted in a defect of approximately 3/4 of the entire lower lip and a full-layer skin defect from the vermilion to the gingivobuccal sulcus at the right corner of the mouth...

Patients complaining of swelling and hematoma caused by contusion of the face can be easily seen in the emergency room. Most of the treatments were conservative treatments such as ice bag application, mild compression dressing, and massage. During the follow-up, fibrosis progression due to hematoma was frequently observed in the contusion site. When hematoma or fibrosis is confirmed, hyaluronidase (H-lase) 1,500 IU and 2 mL of normal saline were mixed and subcutaneously injected in crisscross manner. To evaluate the improvement of hematoma before and after hyaluronidase injection, three plastic surgeons evaluated using the Vancouver scar scale and compared preoperative and postoperative images...

Bommie Florence Seo, Kyo Joon Kang, Sung-No Jung, Jun Hee Byeon
Skeletal cavernous hemangiomas are rare, benign tumors that may involve the supraorbital rim and orbital roof. However, such involvement is extremely rare. We report a case of skeletal cavernous hemangioma of the frontal bone involving the orbital roof and rim. En bloc excision and reconstruction, using a calvarial bone graft for the orbital roof and rim defect, was performed. It is important not only to perform total excision of skeletal cavernous hemangiomas, but to properly reconstruct the defects after the total excision since several complications can arise from an orbital roof and rim defect...

Sinonasal intestinal-type adenocarcinoma is a rare neoplasm which can be diagnosed by pathologic report. Nasal obstruction, epistaxis, and rhinorrhea are common symptoms, but presenting with a benign-looking palpable mass is also possible. This is a report of our experience in diagnosing and treating a sinonasal intestinal-type low grade adenocarcinoma. A 63-year-old man initially presented with a rapidly growing palpable mass in the glabella region for 4 months. A malignancy of sinus origin was suspected on imaging studies...

Merkel cell carcinoma (MCC) is an uncommon neuroendocrine cutaneous tumor with poor prognosis. It has the high rate of recurrence, mortality, regional nodal involvement, and distant metastases. It is difficult to diagnose MCC because of its non-specific clinical findings. It usually occurs on sun-exposed areas of the skin, mostly at head and neck. There is a difference in the incidence and prognosis according to site in the head and neck. However, there is no consented site-specific diagnosis, treatment or follow-up protocol for MCC at the head and neck...

Fibrous dysplasia (FD) is a rare, benign bone disease with abnormal bone maturation and fibroblastic proliferation. Optimal treatment of zone 1 craniofacial FD is radical resection and reconstruction. To achieve of structural, aesthetic, and functional goals, we use three-dimensionally designed calvarial bone graft for reconstruction of zygomatic defect after radical resection of FD. The authors used a rapid-prototyping model for simulation surgery for radical resection and immediate reconstruction. Donor site was selected from parietal bone reflect shape, contour, and size of defect...

BACKGROUND: Cases of simultaneous multiple skin cancers in a single patient have become more common. Due to the multiplicity of lesions, reconstruction in such cases is more difficult than after a single lesion is removed. This study presents a series of patients with multiple facial skin cancers, with an analysis of the surgical removal, reconstruction process, and the results observed during follow-up. METHODS: We reviewed 12 patients diagnosed with multiple skin cancers on the face between November 2004 and March 2016...

BACKGROUND: Autogenous bone grafts have several limitations including donor-site problems and insufficient bone volume. To address these limitations, research on bone regeneration is being conducted actively. In this study, we investigate the effects of a three-dimensionally (3D) printed polycaprolactone (PCL)/tricalcium phosphate (TCP) scaffold on the osteogenic differentiation potential of adipose tissue-derived stem cells (ADSCs) and bone marrow-derived stem cells (BMSCs). METHODS: We investigated the extent of osteogenic differentiation on the first and tenth day and fourth week after cell culture...

Jae-Hyuk Yang, Suk Choo Chang, Jin Yong Shin, Si-Gyun Roh, Nae-Ho Lee
BACKGROUND: The facial bone has a complex structure compared to other bones, and various types of fractures can occur due to its characteristics. Among them, in comminuted fractures of anterior maxillary wall, multiple depressed and impacted bony segments cannot be reduced easily when performing internal fixation using plates and screws or wires, and inadequate restoration leads to a range of complications. This paper introduces an alternative technique using a resorbable mesh with fibrin glue to restore comminuted fractures of anterior maxillary wall...

Velopharyngeal insufficiency (VPI) is a common complication after primary palatoplasty. Although the several surgical treatments of VPI have been introduced, there is no consensus guide to select the optimal surgical treatment for VPI patients. The selection of surgical treatment for VPI depends on a multimodal patient evaluation, such as perceptual speech evaluation, nasometery and nasoendoscopy. We can provide more adequate treatment for VPI through the deeper understanding of anatomy and physiology in VPI...

The nose is an important landmark of the face and its shape and beauty is of significant concern. The columella is the subunit between the two nostrils that provides support and projection to the nasal tip and has functional role in nostrils, as well as aesthetic. Ethiology for columellar absence or deficiency is diverse, and it is one of the most complex nasal subunits to reconstruct because of its narrow horizontal dimension, its tenuous vascularity and limited availability of adjacent tissue. We present a patient with columellar, membranous septum and upper lip defect, due to oncological resection...
