Cranioplasties are common procedures in plastic surgery. The use of tissue expansion (TE) in staged cranioplasties is less common. We present two cases of cranioplasties with TE and systematically review literature describing the use of TE in staged cranioplasties and postoperative outcomes. A systematic review was performed by querying multiple databases. Eligible articles include published case series, retrospective reviews, and systematic reviews that described use of TE for staged bony cranioplasty. Data regarding study size, patient demographics, preoperative characteristics, staged procedure characteristics, and postoperative outcomes were collected. Of 755 identified publications, 26 met inclusion criteria. 85 patients underwent a staged cranioplasty with TE. Average defect size was 122 cm², and 30.9% of patients received a previous reconstruction. Average expansion period was 14.2 weeks. The most common soft tissue closures were performed with skin expansion only (75.3%), free/pedicled flap (20.1%), and skin graft (4.7%). The mean postoperative follow-up time was 23.9 months. Overall infection and local complication rates were 3.53 and 9.41%, respectively. The most common complications were cerebrospinal fluid leak (7.1%), hematoma (7.1%), implant exposure (3.5%), and infection (3.5%). Factors associated with higher complication rates include the following: use of alloplastic calvarial implants and defects of congenital etiology (p = 0.023 and 0.035, respectively). This is the first comprehensive review to describe current practices and outcomes in staged cranioplasty with TE. Adequate soft tissue coverage contributes to successful cranioplasties and TE can play a safe and effective role in selected cases.

An arteriovenous fistula (AVF) from the renal artery following a penetrating abdominal trauma is not common. We report the case of a 19-year-old male who presented with a knife stab wound in the right upper quadrant. Due to unstable vital signs and to the protrusion of the mesentery through the stab wound, providing definite evidence of peritoneal violation, an emergent exploratory laparotomy was carried out. There were injuries at the proximal transverse mesocolon and the second portion of the duodenum, with bile leakage. There was also a mild amount of retroperitoneal hematoma near the right kidney, without signs of expansion or pulsation. The mesocolon and the duodenum were repaired. After the operation, abdominal computerized tomography (CT) was performed, which revealed contrast from the right renal artery shunting directly into the vena cava. Transcatheter arterial embolization with a coil and vascular plug was performed, and the fistula was repaired. The patient recovered completely and was discharged without complication. For further and thorough evaluation of an abdominal trauma, especially one involving the retroperitoneum, a CT scan is recommended, when possible, either prior to surgery or after surgery when the patient is stabile. Furthermore, a lateral retroperitoneal hematoma and an AVF after a penetrating trauma may not always require exploration. Sometimes, it may be safely treated non-operatively or with embolization.

Purpose: Although the autogenous tissue transfer has been the mainstay of the breast reconstruction, concern for the donor site morbidity can lead to the superseded method using tissue expander with implant or permanent expander-implant. However, the additional procedure of tissue expansion possibly cause discomfort and raise the cost. We tried to verify the efficacy of using the saline-filled breast implant by itself for the safe and convenient immediate breast reconstruction modality if the patients have small, round and non-ptotic breasts and the sufficient breast skin can be saved with mastectomy. Methods: From July 2002 to July 2005, 29 breasts of 26 patients were restored only with the saline-filled breast implant immediately after the skin sparing or nipple-areolar skin sparing mastectomy in Asan Medical Center. A pocket with pectoralis major and serratus anterior muscle was created and the implant was covered with this muscle pocket. Simultaneous contralateral augmentation was performed in patients whose mastectomy specimen weighed less than 100g. Results: Using only the saline-filled breast implant resulted in the successful reconstruction with few complications including partial necrosis of nipple areolar skin (five cases, 17.2%), capsular contracture (three cases, 10.3%), hematoma (one case, 3.4%), depigmentation of areolar skin (one case, 3.4%), hypertrophic scar (one case, 3.4%), which were all healed by conservative management. There were no significant complications such as implant exposure and subsequent removal. Conclusion: Immediate breast reconstruction only with the saline-filled breast implant can be a satisfactory alternative option for the patients whose breast is small, round and non-ptotic, especially when the nipple-areolar skin of the breast is preserved in the mastectomy.

This report details a case of unexpected, severe post-operative cerebral edema following cranioplasty. We discuss the possible pathological mechanisms of this complication. A 50-year-old female was admitted to our department with sudden onset of stuporous consciousness. A brain computed tomography (CT) revealed a subarachnoid hemorrhage with intracranial hemorrhage and subdural hematoma. Emergency decompressive craniectomy and aneurysmal neck clipping were performed. Following recovery, the decision was made to proceed with an autologous cranioplasty. The cranioplasty procedure was free of complications. An epidural drain was placed and connected to a suction system during skin closure to avoid epidural blood accumulation. However, following the procedure, the patient had a seizure in the recovery room. An emergency brain CT scan revealed widespread cerebral edema, and the catheter drain was clamped. The increased intracranial pressure and cerebral edema were controlled with osmotic diuretics, corticosteroids, and antiepileptic drugs. The edema slowly subsided, but new low-density areas were noted in the brain on follow-up CT 1 week later. We speculated that placing the epidural drain on active suction may have caused an acute decrease in intracranial pressure and subsequent rapid expansion of the brain, which impaired autoregulation and led to reperfusion injury.

A clinical analysis was performed on 97 cases of chest injuries experienced at Department of Thoracic and cardiovascular Surgery, Armed Forces Capital Hospital during 2 years period from 1986 to 1988. Of 97 patients of chest trauma, 39 cases were result from penetrating injuries whereas 58 cases were from non-penetrating injuries, and there were 77 cases of hemothorax and / or pneumothorax, 47 of rib fracture, 8 of foreign body, 6 scapular and clavicle fracture, 5 of diaphragmatic injuries, 4 of paraplegia. The majority of chest injuries were encounted in the age group between 21 and 30 years-old, mean age was 25.9 years-old and all cases were male except one. Gun-shot wound was the most common cause in the penetrating injuries and the majority of non-penetrating chest injury patients were traffic accident and fist or kick accounted for next. The principles of therapy for chest trauma were rapid expansion of the lung by closed thoracostomy[45 cases] and thoracentesis only[3 cases] but thoracotomy done at 27 cases because of massive bleeding or intrapleural hematoma, foreign body, cardiac injury, diaphragmatic injury and bronchial rupture. The over-all mortality was 2.07 percent[2 cases among all], a case was from penetrating injuries and another was from non-penetrating injuries.

Robotic surgery facilitates surgical procedures by employing flexible arms with multiple degrees of freedom and providing high-quality 3-dimensional imaging. Robot-assisted nipple-sparing mastectomy with immediate reconstruction is currently performed to avoid breast scars. Four patients with invasive ductal carcinoma underwent robot-assisted nipple-sparing mastectomy and immediate robot-assisted expander insertion. Through a 6-cm incision along the anterior axillary line, sentinel lymph node biopsy and nipple-sparing mastectomy were performed by oncologic surgeons. The pectoralis major muscle was elevated, an acellular dermal matrix (ADM) sling was created with robotic assistance, and an expander was inserted into the subpectoral, sub-ADM pocket. No patients had major complications such as hematoma, seroma, infection, capsular contracture, or nipple-areolar necrosis. The mean operation time for expander insertion was 1 hour and 20 minutes, and it became shorter with more experience. The first patient completed 2-stage prosthetic reconstruction and was highly satisfied with the unnoticeable scar and symmetric reconstruction. We describe several cases of immediate robot-assisted prosthetic breast reconstruction. This procedure is a feasible surgical option for patients who want to conceal surgical scars.

Cherubism is a rare fibro-osseous condition characterized by bilateral expansion of the mandible and maxilla. Due to its rarity, treatment guidelines for cherubism have not been clearly established. Observation without surgical intervention is typically recommended, as cherubism often regresses spontaneously after puberty. However, a surgical intervention may be necessary if aggressive lesions lead to severe complications. In this report, we present a case involving surgical management of cherubism that did not spontaneously regress until early adulthood. An 18-year-old man was diagnosed with cherubism, presenting characteristic upward-looking eyes and a swollen face. He strongly desired surgical management. Gross contouring of the mandible was performed using an osteotome. Subsequently, delicate contouring was performed by bone burring and curettage. The remaining multiple locular bony defects were filled with demineralized bone matrix. No major complications, including infection and hematoma, occurred during the 8-month follow-up period. The facial contour remained stable without the aggravation of cherubism. The patient was satisfied with the cosmetic results. Considering that cherubism is a rare disease globally, with few reported cases in Korea, and that treatment guidelines are not clearly established, we anticipate that the results of this case will contribute to the development of future protocols for treating cherubism.

The defects of the abdominal wall could be brought about either congenitally, for instances in such cases as omphalocele or gastroschisis, or by various acquired causes-trauma, excision of tumors, excision of burn scar, tissue necrosis caused by infection, hematoma after abdominal surgery, tissue necrosis after radiation therapy and so on. As for the techniques of the reconstruction of the abdominal wall defects, many authors have developed and reported diverse methods. To summarize, primary closure, skin graft, local skin flaps, various myocutaneous flaps, free flap, fascia graft, artificial mesh, tissue expansion, etc could be used in the reconstruction of the abdominal wall defects. The periumbilical perforator-based island skin flap has a many advantages such as no significant sacrifice of the rectus abdominis muscle, wide rotation arc, reliable blood flow of the perforator, short elevation time for flap, and for middle-aged, obese patients, the donor site may be the best from the cosmetic point of view. We used perforator-based island skin flap in 5 cases with reasonable result from March 1999 to May 2001. There were no significant complications and donor sites could be repaired primarily.

Objective : Adequate management of increased intracranial pressure (ICP) is critical in patients with traumatic brain injury (TBI), and decompressive craniectomy is widely used to treat refractory increased ICP. The authors reviewed and analyzed complications following decompressive craniectomy for the management of TBI. Methods : A total of 89 consecutive patients who underwent decompressive craniectomy for TBI between February 2004 and February 2009 were reviewed retrospectively. Incidence rates of complications secondary to decompressive craniectomy were determined, and analyses were performed to identify clinical factors associated with the development of complications and the poor outcome. Results : Complications secondary to decompressive craniectomy occurred in 48 of the 89 (53.9%) patients. Furthermore, these complications occurred in a sequential fashion at specific times after surgical intervention; cerebral contusion expansion ($2.2{\pm}1.2$ days), newly appearing subdural or epidural hematoma contralateral to the craniectomy defect ($1.5{\pm}0.9$ days), epilepsy ($2.7{\pm}1.5$ days), cerebrospinal fluid leakage through the scalp incision ($7.0{\pm}4.2$ days), and external cerebral herniation ($5.5{\pm}3.3$ days). Subdural effusion ($10.8{\pm}5.2$ days) and postoperative infection ($9.8{\pm}3.1$ days) developed between one and four weeks postoperatively. Trephined and post-traumatic hydrocephalus syndromes developed after one month postoperatively (at $79.5{\pm}23.6$ and $49.2{\pm}14.1$ days, respectively). Conclusion : A poor GCS score ($\leq$ 8) and an age of $\geq$ 65 were found to be related to the occurrence of one of the above-mentioned complications. These results should help neurosurgeons anticipate these complications, to adopt management strategies that reduce the risks of complications, and to improve clinical outcomes.

Purpose: Common complications of immediate breast reconstruction with implant are capsular contracture, malposition of implant, hematoma and seroma. Especially, the most severe complication is implant exposure caused by inflammation or necrosis of skin flap margin of mastectomy site. This article reports the experience of cases of salvage in such an exposure of implant. Methods: From July, 2002 to Feb., 2009, sixty-five patients who underwent immediate breast reconstruction with implant were retrospectively analyzed. Exposure of implant was happened in 5 of 65 patients and they were treated at out patient district. Two of five patients were reconstructed with saline implnt and all of them underwent the enveloping of the implant with AlloDerm$^{(R)}$ and Serratus muscle flap. Remaning three patients were reconstructed with silicone implant and all of them underwent the enveloping of the implant with AlloDerm$^{(R)}$. Results: In the group of patients who underwent reconstruction with saline implant, implant exposure was found in one patient due to partial necrosis of the margin of skin flap and debridement and primary repair were done. In the other one patient, dressing with antibiotic ointment were done. And debridement and primary repair were proceeded. In the group of patients who underwent reconstruction with silicone implant, implant exposure was found in one patient. After removal of the implant, tissue expansion was done and a new silicone implant was inserted. Implant exposure were found in the other two patients, antibiotics ointment application and primarily repaired. Conclusion: It was the common knowledge that the exposed implant should be removed. But salvage of the exposed implants may be possible with proper treatment. Four of five patients (80%) with exposed breast implant were salvaged with conservative management.
