Background: The study aimed to evaluate nasal reconstruction techniques customized for Asians. The currently available nasal reconstruction guidelines are based on Caucasian patients, and their applicability is limited in Asian patients due to differences in anatomical and structural features. Methods: A retrospective analysis was performed of the medical records of 76 patients who underwent nasal reconstruction at a single center between January 2010 and June 2020. A comprehensive evaluation was conducted of patients' baseline demographics and clinical characteristics, including age, sex, medical history, defect size and location, reconstructive procedure, pathological diagnosis, postoperative complications, and recurrence. Results: In 59 cases (77%), nasal defects resulted from tumor ablation, and the remaining 17 cases involved post-traumatic (20%) and infection-induced (3%) tissue damage. The most common defect location was the alae, followed by the sidewalls, tip, and dorsum. Forehead flaps were the most commonly used reconstructive technique, followed by nasolabial advancement flaps, rotation flaps, and skin grafts. Each procedure was applied considering aspects of structural anatomy and healing physiology specific to Asians. Complications included nasal deformity, hypertrophic scarring, secondary infection, and partial flap necrosis, but no cases required additional surgical procedures. Tumors recurred in two cases, but tumor recurrence did not significantly affect flap integrity. Conclusion: Nasal reconstruction techniques applied considering Asians' facial features resulted in fewer postoperative complications and higher patient satisfaction than the approaches that are currently in widespread use. Therefore, this study is expected to serve as an essential reference for establishing treatment guidelines for nasal reconstruction in Asians.

Purpose: Subciliary approaches to orbitozygomatic fractures have high incidence of complications such as scleral show and ectropion. Abnormal rearrangement of eyelid flaps may be a very important factor to induce abnormal cicatrical and consequent contracture. To prevent this problem, we used temporary lower eyelid suspension. Methods: A total of two hundred five patients were investigated for lower eyelid complication of orbitozygomatic fractures that underwent reconstruction with subciliary approach. The lower eyelid margin was pulled up toward the forehead using lower eyelid suspension suture to stretch the lower lid flaps. The lid suspension was maintained for one day after surgery. Results: The complications of the lower eyelid were in 15 cases(7.3%); seven cases(3.4%) of visible depressed scar, three cases(1.4%) of scleral show, two cases(1%) of ectropion, two cases(1%) of conjunctival swelling and one case(0.5%) of hematoma. Conclusions: The lower eyelid suspension seems to allow adhering lid flap in proper anatomical position and in the status of the maximal stretch and consequently preventing the severe complications such as scleral show and ectropion caused by scar contraction after subciliary approach.

Patients with Crouzon syndrome have increased risks of cerebrospinal fluid rhinorrhea and meningoencephalocele after LeFort III osteotomy. We report a rare case of meningoencephalocele following LeFort III midface advancement in a patient with Crouzon syndrome. Over 10 years since it was incidentally found during transnasal endoscopic orbital decompression, the untreated meningoencephalocele eventually led to intermittent clear nasal discharge, frontal headache, and seizure. Computed tomography and magnetic resonance imaging demonstrated meningoencephalocele in the left frontal-ethmoid-maxillary sinus through a focal defect of the anterior cranial base. Through bifrontal craniotomy, the meningoencephalocele was removed and the anterior cranial base was reconstructed with a pericranial flap and split calvarial bone graft. Secondary frontal advancement was concurrently performed to relieve suspicious increased intracranial pressure, limit visual deterioration, and improve the forehead shape. Surgeons should be aware that patients with Crouzon syndrome have the potential for an unrecognized dural injury during LeFort III osteotomy due to anatomical differences such as inferior displacement and thinning of the anterior cranial base.

A 59-year-old woman presented to our clinic with a 3.5×3-cm protruding mass on her forehead. A skull X-ray revealed a radiolucent osteolytic lesion on the left side of the frontal bone. Additionally, computed tomography showed a 3.1×1.7×3.6-cm mass exhibiting a "sunburst" pattern situated between the outer and inner tables of the skull, just superior and lateral to the left frontal sinus. This pattern suggested the presence of an intraosseous vascular malformation (IVM). The lesion was approached via a bicoronal incision. En-bloc resection was performed, removing the mass along with approximately 0.5 cm of the surrounding normal bone without injury to the exposed frontal sinus mucosa. The exposed mucosa was reinforced with a galeal flap, and cranioplasty with bone cement was performed to repair the resulting bony defect. Pathological examination confirmed a diagnosis of intraosseous cavernous-type malformation with mixed cavernous and capillary histological features. We report this case of IVM and review the existing literature, highlighting the satisfactory functional and aesthetic outcomes after surgery.

Purpose: Frontal sinus fractures are relatively less common than other facial bone fractures. They are commonly concomitant with other facial bone fractures. They can cause severe complications but the optimal treatment of frontal sinus fractures remains controversial. Currently, many principles of treatment were introduced variously. The authors present valid and simplified protocols of treatment for frontal sinus fractures based on fracture pattern, nasofrontal duct injury, and complications. Methods: A retrospective chart review was performed on 36 cases of frontal sinus fractures between January, 2004 and January, 2009. The average age of patients was 33.7 years. Fracture patterns were classified by displacement of anterior and posterior wall, comminution, nasofrontal duct injury. These fractures were classified in 4 groups: I. anterior wall linear fractures; II. anterior wall displaced fractures; III. anterior wall displaced and posterior wall linear fractures; IV. anterior wall and posterior wall displaced fractures. Also, assessment of nasofrontal duct injury was conducted with preoperative coronal section computed tomographic scan and intraoperative findings. Patients were treated with various procedures including open reduction and internal fixation, obliteration, galeal frontalis flap and cranialization. Results: 12 patients are group I (33.3 percent), 14 patient were group II (38.8 percent), group III, IV were 5 each (13.9 percent). Frontal sinus fractures were commonly associated with zygomatic fractures (21.8 percent). 9 patients had nasofrontal duct injury. The complication rate was 25 percent (9 patients), including hypoesthesia, slight forehead irregularity, transient cerebrospinal fluid leakage. Conclusion: The critical element of successful frontal sinus fracture repair is precise diagnosis of the fracture pattern and nasofrontal duct injury. The main goal of management is the restoration of the sinus function and aesthetic preservation.

Tissue expansion has now been widely used in various soft tissue defects and deformities. It is to reconstruct the lesion site by providing donor tissue of the same color, texture, and similar thickness and sensation with minimal scar formation and minor donor site morbidity. It is achieved through using a temporary expander capable of accumulating normal saline. Internal pressure from expander exerts its force on the flap, which gradually expands to provide additional tissue for reconstruction. We have applied tissue expander in three patients. The first case was soft tissue loss on the left forehead. The second case was multiple scar formation on the left mandibular angle and upper cervical area. The third case was scar contraction on the right cheek. All cases have been successfully reconstructed without complications.

Purpose: Angiosarcoma of the scalp is unusual vascular tumor originating from endothelial cell. Angiosarcoma is an aggressive tumor with high propensity for both local recurrence and distant metastasis. We report 2 cases of angiosarcoma having poor prognosis recently. Methods: Case 1 was a 67 - year - old male patient. He visited the hospital with a $3{\times}5cm$ sized discolored mass in forehead. It began at one month ago from coming to the hospital. Case 2 was a 64 - year - old male patient. He visited for our hospital to remove a $4{\times}5cm$ sized scalp mass. He had a pruritis on scalp from 9 months ago before coming to the hospital. Despite of the conservative treatments, the wound was not healed and advanced necrotic lesion with hemorrhage. Results: Case 1 diagnosed as an angiosarcoma. He underwent a radical operation 5 times. But the tumor expanded multiple area in dura & frontal area of the brain. The patient rejected the treatment any more. And he died one month later. Case 2 diagnosed as an angiosarcoma and metastased to skull in MRI. He got a radical resection including cranium. Three months later, it recurred to ipsilateral Sternocleidomastoideus muscle. He got a additional operation & started radiotherapy. And now he is receiving chemotherapy, but the recurred lesion is expanding. Conclusion: Angiosarcoma is a highly malignant tumor. Especially it arises in vascularized area, it easily metastases. So it is the best to treat angiosarcoma with surgery included wide margins. Despite of the lesion is small, we remember that angiosarcoma is a tumor that consider to metastases.

Background: Localized scleroderma is characterized by a thickening of the skin from excessive collagen deposits. It is not a fatal disease, but quality of life can be adversely affected due to changes in skin appearance, joint contractures, and, rarely, serious deformities of the face and extremities. We present six cases of localized scleroderma in face from our surgical practice. Methods: We reviewed six localized scleroderma cases that were initially treated with medication and then received follow-up surgery between April 2003 and February 2015. Six patients had facial lesions. These cases presented with linear dermal sclerosis on the forehead, oval subcutaneous and dermal depression in the cheek. Results: En coup de sabre (n=4), and oval-shaped lesion of the face (n=2) were successfully treated. Surgical methods included resection with or without Z-plasty (n=3), fat graft (n=1), dermofat graft (n=1), and adipofascial free flap (n=1). Deformities of the affected parts were surgically corrected without reoccurrence. Conclusion: We retrospectively reviewed six cases of localized scleroderma that were successfully treated with surgery. And we propose an algorithm for selecting the best surgical approach for individual localized scleroderma cases. Although our cases were limited in number and long-term follow-up will be necessary, we suggest that surgical management should be considered as an option for treating scleroderma patients.

Purpose: The prevalence of antibiotic-resistant Streptococcus pneumoniae meningitis has increased worldwide. There are some reports about postoperative antibiotic-resistant Streptococcus pneumoniae infection after craniofacial surgery, but, there is no report in Korea. We present a report on the treatment of postoperative multidrug-resistant Streptococcus pneumoniae (MRSP) meningitis and sepsis after craniofacial surgery based on our experience. Methods: The patient was a 7-year-old boy with Crouzon's disease who was treated by fronto-orbital bar advancement. Intraoperatively, frontal sinus opening was seen during osteotomy which was covered with forehead galeopericranial flap. MRSP meningitis was diagnosed after the surgery, he was treated with intravenous vancomycin, meropenem, and levofloxacin. Results: The patient was treated successfully after 3 weeks of intravenous antibiotics treatment. During the 8 month follow-up period, there was no neurologic sequelae. Conclusion: Postoperative infection after craniofacial surgery is an important phenomenon that needs immediate recognition. Prevention, early diagnosis, and treatment immediate after onset are important as countermeasures against postoperative drug-resistant bacterial infection. To prevent adverse outcome and reoperation, proper antibiotics treatment should be performed.

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.
