This study was performed to evaluate the effects of preoperative and postoperative radiation on the healing of surgical wound and the relationship between surgery-radiation interaval histopathologically. Experimental animals were 64 rats of Sprague-Dawely strain weighing about 180grams. In postoperative radiation group, a single dose of 1000 rads irradiation was delivered on 1,2,3, weeks after incision and 24 animals were sacrificed on the 1st, 3rd, 7th, and 14th day after radiation. In preoperative radiation group incision was performed on 1,2,3,4 weeks after a single dose of 1000 rads and 32 animals were sacrificed on the 1st, 3rd, 7th, and 14th after incision. Tissue specimens were prepared as usual methods and stained with hematoxyline-eosin for ordinary light microscopy. Histopathologic study revealed the following favorable results : 1. In 2 and 3 weeks radiation group after incision, the healing process was unaffected by radiation. 2. In 1 week radiation group after incision, the healing process was slightly retarded, as compared with 2,3 weeks radiation group after incision. 3. In 1,2 and 3 weeks incision group after radiation, the healing process appeared about 7 days later than that of control group. 4. In 4 weeks incision after radiation, the healing process was unaffected by radiation.

Split-thickness skin grafting (STSG) is the gold standard for coverage of acute burns and reconstructive wounds. However, the choice of the donor site for STSG varies among surgeons, and the scalp represents a relatively under-utilized donor site. Understanding the validity of potential risks will assist in optimizing wound management. A comprehensive literature search was conducted of the PubMed database to identify studies evaluating scalp skin grafting in human subjects published between January 1, 1964 and December 31, 2019. Data were collected on early and late complications at the scalp donor site. In total, 27 articles comparing scalp donor site complications were included. The selected studies included analyses of acute burn patients only (21 of 27 articles), mean total body surface area (20 of 27), age distribution (22 of 27), sex (12 of 27), ethnicity (5 of 27), tumescent technique (21 of 27), depth setting of the dermatome (24 of 27), number of harvests (20 of 27), mean days of epithelization (18 of 27), and early and late complications (27 of 27). The total rate of early complications was 3.82% (117 of 3,062 patients). The total rate of late complications was 5.19% (159 of 3,062 patients). The literature on scalp skin grafting has not yet identified an ideal surgical technique for preventing donor site complications. Although scalp skin grafting provided superior outcomes with fewer donor site complications, there continues to be a lack of standardization. The use of scalp donor sites for STSG can prevent early and late complications if proper surgical planning, procedures, and postoperative care are performed.

The common causes of neck closed injuries are automobile accidents and sports troubles; open injuries are gun-shot wounds and stab wounds. Generally, the treatment of wide laryngopharyngeal injuries consists of tracheostomy for adequate airway, simple repair and, later, surgical intervention for chronic laryngeal stenosis and hypopharyngeal reconstruction. Recently, authors experienced a case of extensive communicated wound with large defect on the layngopharyngeal structures and anterior neck skin. This large defect was reconstructed with horizontal cervical skin flap after total laryngectomy.

Gunshot wounds to the face are often dramatic at the time of presentation. Although care must be individualized, protocol approach helps the clinician rapidly evaluate patient and plan treatment. Early X-ray films help to determine the precise trajectory. Rapid neurologic assessment and early CT scanning based on physical examination ot trajectory will allow for identification of even occult injuries early. Lead poisoning arising from bullet lead in the synovial cavity of the hip, synovial cavity of the chest and pleural space have been reported. A combination of surgical debridement and chelation therapy with oral succimer produce a satisfactory outcome. We have managed a patient with Lt facial gunshot wound and Lt mandible angle fracture by open reduction of angle fracture and surgical removal of remnant bullet and medially advanced cheek skin flap. We have obtained good result and report this case with review of literatures.

Pressure sores are a common complication of hospitalized patients. However, It is often impossible to correct surgically because the general conditions of these patients are poor. It is known that the hydrogel has a powerful autolytic effect by providing moist environments and facilitates wound healing and hydrocolloid dressing is also known to promotes granulation tissue formation and epithelialization. The patients were treated with hydrogel(Purion $gel^{(R)}$, Coloplast A/S, Denmark) and hydrocolloid dressing (Comfeel Plus Transparent $Dressing^{(R)}$, Coloplast A/S, Denmark) after surgical debridement of pressure sores progressed to stage III(n=2) and IV(n=7). This combination treatment could facilitate to debride the nectrotic tissue and promote granulation tissue formation epithelialization simultaneously. We could achieve complete healing of pressure sores using the combination treatment without requiring surgical correction. In conclusion, hydrogel in combination with hydrocolloid dressing is effective in acheiving complete healing of progressed pressure sores.

For recent years, use of autologous fat injection has increased significantly in facial contouring surgery. Along with such increase in use, complications like atypical mycoplasma infection have been also on the increasing trend. The authors report two cases of Mycobacterium chelonae infection that occurred after autologous fat injection. Patients were treated as infection that resistant to common antibiotics and results were negative to routine culture and Gram staining. Acid-fast bacillus stain, polymerase chain reaction (PCR) test and mycobacterial cultures were conducted for diagnosis under suspicion of atypical mycoplasma infection. Then, combination antibiotics therapy, surgical treatment, and steroid injection were performed for treatment. Both patients were diagnosed with Mycobacterium chelonae in PCR test. They were positive to mycobacterial cultures. Combination antibiotics therapy was repeated to improvement of symptom. However, they could not be free from side effects such as deformation in facial contour, scar and pigmentation even after full recovery. When chronic wound infections after autologous fat injection, we must suspect atypical or mycobacterial infection and conduct examinations for a early diagnosis and proper antibiotic therapy that is effective to the nontuberculous mycobacteria.

Local flaps exhibit excellent color matching that no other type of flap can compete with. Moreover, surgery using a local flap is easier and faster than surgery using a distant or free flap. However, local flaps can be much more difficult to design. We designed 2 templates to plan a V-Y rotation advancement flap. The template for a unilateral V-Y rotation advancement flap was used on the face (n=5), anterior tibia (n=1), posterior axilla (n=1), ischium (n=1), and trochanter (n=2). The template for a bilateral flap was used on the sacrum (n=8), arm (n=1), and anterior tibia (n=1). The causes of the defects were meningocele (n=3), a decubitus ulcer (n=5), pilonidal sinus (n=3), and skin tumor excision (n=10). The meningocele patients were younger than 8 days. The mean age of the adult patients was 50.4 years (range, 19-80 years). All the donor areas of the flaps were closed primarily. None of the patients experienced wound dehiscence or partial/total flap necrosis. The templates guided surgeons regarding the length and the placement of the incision for a V-Y rotation advancement flap according to the size of the wound. In addition, they could be used for the training of residents.

The complications of a tracheotomy are caused by inappropriate surgical techniques, unsuitable cannula selections, and improper wound care. Among these, the solutions to problems of surgical technique and wound care have been reported in many articles. Detailed methods for preventing complications by the cannula are rare. The authors tried to find a way of preventing complications by the cannula Materials and Methods : The authors analized complications in 70 patients who had a temporary tracheotomy and were wearing a cannula. And the complications were compared between 4 commercial cannulas used in our institute. The examination methods used were a simple neck lateral radiogram and flexible endoscopy. Results： The order of most commonly found complications were as followed; at the suprastoma, end of cannula, level of tracheotomy, and infrastoma. Among 4 cannulas, a particular product had so many complications compared to the other 3 cannulas. The most common cause of complications was unsuitable cannula. All complications were cured with no sequelae. Flexible endoscopy is far superior to radiologic exam for detecting tracheal complications. Conclusion： Flexible endoscopy through the tracheostoma is very helpful for detecting complications early and determining if a proper cannula is used, which can prevent further complications such as stenosis or innominate artery rupture. The authors, therfore, recommend using the flexible endoscopy to all patients wearing tracheotomy tubes. Some complications can simply be prevented by replacing the one to another cannula properly fit for the individual patients. Various cannulas should be prepared at the hospital because the tracheal curvature and distance of skin to trachea are individualized.

Posttraumatic pseudoaneurysm of the face is caused by blunt, penetrating, or surgical trauma. Although its incidence is low, pseudoaneurysm rupture can cause a life-threatening, massive hemorrhage. A 48-year-old man visited our emergency center due to a fall-down accident. Three-dimensional computed tomography (CT) showed a comminuted zygomaticomaxillary complex fracture of the left face. After open reduction and internal fixation, the surgical wound healed without any complications. However, the patient was readmitted 10 days after surgery due to pus-like discharge from the wound. Contrast-enhanced CT to find the abscess unexpectedly revealed a pseudoaneurysm in the left retromaxillary area. Massive oral bleeding occurred on the night of re-hospitalization and emergency surgery was done. The bleeding site was identified as a pseudo-aneurysmal rupture of the posterior superior alveolar artery in the retromaxillary area. Hemostasis was achieved by packing Vaseline gauze in the maxillary sinus using an endoscope. Delayed rupture and massive bleeding of posttraumatic retromaxillary pseudoaneurysm after a zygomaticomaxillary fracture is a low-probability, but high-impact event. Therefore, additional contrast-enhanced CT should be considered to evaluate the possibility of a posttraumatic pseudoaneurysm in cases of severe comminuted zygomaticomaxillary fracture.

Background We report the efficacy of a dual-plane approach using a Dufourmentel skin flap with a purse-string suture of the de-epithelized dermis to manage pseudoaneurysm at the vascular access site for hemodialysis. Methods A retrospective analysis was conducted of 61 patients from 2013 to 2018 with pseudoaneurysms at the arteriovenous fistula or graft who were treated with rhomboid excision, vessel repair with a purse-string suture, and a full-thickness Dufourmentel skin flap. The success rate was defined as the probability of complete wound closure and intact vascular access patency without infection or other complications. Results The success rate was 93.4% at 6 months postoperatively. Complications included newly occurring pseudoaneurysms (n=2), wound dehiscence (n=1) and bleeding (n=1). There were no complications such as stenosis or thrombosis from the procedure. Conclusions A dual-plane approach using a Dufourmentel skin flap with a purse-string suture for vessel repair was shown to be a favorable option for managing stable, small (diameter <2 cm) pseudoaneurysms without infection, rapid expansion, or patency issues of the vascular access.
