ABSTRACT
Background@#The existing literature has comprehensively examined the benefits of specialized wound-care services and multidisciplinary team care. However, information on the development and integration of wound-dressing teams for patients who do not require specialized wound care is scarce. Therefore, the present study aimed to elucidate the benefits of a wound-dressing team by reporting our experiences with the establishment of a wounddressing team. @*Methods@#The wound-dressing team was established at Korea University Guro Hospital.Between July 2018 and June 2022, 180,872 cases were managed for wounds at the wounddressing team. The data were analyzed to assess the types of wounds and their outcomes.In addition, questionnaires assessing the satisfaction with the service were administered to patients, ward nurses, residents/internists, and team members. @*Results@#Regarding the wound type, 80,297 (45.3%) were catheter-related, while 48,036 (27.1%), 26,056 (14.7%), and 20,739 (11.7%) were pressure ulcers, dirty wounds, and simple wounds, respectively. In the satisfaction survey, the scores of the patient, ward nurse, dressing team nurse, and physician groups were 8.9, 8.1, 8.2, and 9.1, respectively.Additionally, 136 dressing-related complications (0.08%) were reported. @*Conclusion@#The wound dressing team can enhance satisfaction among patients and healthcare providers with low complications. Our findings may provide a potential framework for establishing similar service models.
ABSTRACT
Sebaceous carcinoma is a malignant neoplasm frequently classified as periocular or extraocular. Extraocular sebaceous carcinoma is a relatively rare tumor commonly appearing in the head and neck region. Furthermore, extraocular sebaceous carcinoma limited to the epithelium, which is called ‘extraocular sebaceous carcinoma in situ’ is extremely rare with less than 10 cases reported in the literature. Herein, we present the case of a 93-year-old female who diagnosed as extraocular sebaceous carcinoma in situ occurring concurrently with actinic keratosis. In the present case, extraocular sebaceous carcinoma in situ as identified without any connection to an adnexal component but concurrent with actinic keratosis. This case is evidence that extraocular sebaceous carcinoma can arise from the epidermis and the tumor cells of intraepidermal squamous neoplasia can differentiate toward malignant sebocytes.

ABSTRACT
BACKGROUND AND OBJECTIVES: Beneficial effects of human adipose-derived stromal vascular fraction (SVF) cell injection on microcirculation have been recently reported in in vitro and in vivo studies. However, no clinical studies have reported its effect in diabetic patients who commonly experience compromised tissue perfusion, regardless of the status of intravascular blood flow. The present piloting study was designed to clinically examine the possibility of SVF cell injection to accelerate microcirculation, particularly in ischemic diabetic feet. METHODS: Ten diabetic feet were included to receive subcutaneous injection of SVF cells around wounds. Transcutaneous partial oxygen pressure (TcPO2) and cutaneous microvascular blood flow were measured before and every four weeks after cell injection until the 12th week visit. RESULTS: TcPO2 values increased from 31.3±7.4 before injection to 46.4±8.2 mmHg at 12 weeks after SVF injection (1.5-fold, p<0.05). Cutaneous microvascular blood flow levels increased from 34.0±21.1 before injection to 76.1±32.5 perfusion unit at 12 weeks after SVF injection (2.2-fold, p<0.05). There were no adverse events related to SVF cell injection. CONCLUSIONS: Results of this study demonstrate that adipose-derived SVF cell injection have the possibility to provide beneficial effects on microcirculation in ischemic diabetic feet.

BACKGROUND: Among the various signs and symptoms of orbital fractures, certain clinical findings warrant immediate surgical exploration, including gaze restriction, computed tomographic (CT) evidence of entrapment, and prolonged oculocardiac reflex. Despite proper surgical reconstruction, prolonged complications such as diplopia and gaze restriction can occur. This article evaluated the prognostic factors associated with prolonged complications of orbital fractures with muscle incarceration. METHODS: The medical records of 37 patients (37 orbits) with an orbital fracture with muscle incarceration from January 2001 to January 2015 were reviewed. The presence of Incarcerated muscle was confirmed via CT, as well as by intraoperative findings. Various factors potentially contributing to complications lasting for over 1 year after the injury were categorized and analyzed, including age, cause of injury, injury-to-operation time, operative time, fracture type, nausea, vomiting and other concomitant symptoms and injuries. RESULTS: All patients who presented with extraocular muscle limitations, positive CT findings, and/or a positive forced duction test underwent surgery. Of the 37 patients, 9 (24%) exhibited lasting complications, such as diplopia and gaze restriction. The mean follow-up period was 18.4 months (range, 1–108 months), while that of patients who experienced prolonged complications was 30.1 months (range, 13–36 months). Two factors were significantly associated with prolonged complications: injury-to-operation time and nausea/vomiting. Loss of vision, worsening of motility, and implant complication did not occur. CONCLUSIONS: Patients who present with gaze limitations, with or without other signs of a blow-out fracture, require a thorough evaluation and emergent surgery. A better prognosis is expected with a shorter injury-to-operation time and lack of nausea and vomiting at the initial presentation.

Nasal-type extranodal natural killer/T-cell lymphoma (ENKTL) is a rare disease presenting with non-specific symptoms, typically originating in the nasal cavity, palate, or midfacial region. Oral cavity is an extremely rare site for this type of lymphoma. In this report, we present a case of palatal perforation and oro-nasal fistula as a manifestation of recurrent ENKTL. Complicated disease entity should be considered when surgeons deal with palatal perforation and oro-nasal fistula.

BACKGROUND: Scar revision is a fundamental technique in the field of plastic and reconstructive surgery. Methods using local flaps, such as a Z-plasty, W-plasty, or geometric broken-line closure, have been used for scar revision. Widening of scars is a frustrating event that most plastic surgeons have encountered. Several therapeutic modalities have been proposed, but frequently, the result is disappointing. We describe our experience with the use of a dermal splinting technique for scar revision. METHODS: We propose a technique by which tension on the wound is applied by tough scar tissue instead of the suture line, thereby reducing the incidence of postoperative widening. This technique was used to treat 21 nonburn scars that had widened:5 scars were facial (3 patients), 8 were on the extremities (6 patients), and 8 were on the torso (5 patients). All scars were at least 4 months old. The operations were performed between January 2003 and December 2012; follow-up was 9 to 24 months. RESULTS: Only one scar widened during the follow-up period. Overall, satisfaction with scar appearance and surgery was assessed with a visual analog scale (VAS). Mean patient satisfaction was 8.1 +/- 0.5. CONCLUSIONS: We recommend this technique in dealing with widened scars in highly tensile areas during revision surgery.

BACKGROUND: In 2004, we reported on 110 consecutive Asian rhinoplasty patients who were treated with the addition of a footplate incision to obtain a greater aesthetic satisfaction. We continue to perform the reported technique with several modifications, and we still think that this method contributes to Asian rhinoplasty. METHODS: A footplate incision was made along the caudal border of the footplate of the medial crura onto the floor of the nasal vestibule. This incision can be made alone or in combination with either endonasal or open rhinoplasty. It enables surgeons to achieve a further tip projection since the pressure of the skin flap is reduced on the tip. In this study, we emphasize a couple of recent changes that we made to our procedure after publication of the prior article. First, we excised the dog-ear that appeared at the caudal end of the extended footplate incision. After making the new tip, a dog ear can be seen at the posterior end of the footplate incision. Second, an inferior columellar dissection was also extended to achieve an additional tip projection and to improve the columello-labial angle. RESULTS: This study included 85 consecutive patients who underwent an aesthetic rhinoplasty using footplate incision techniques between August of 2010 and May of 2013. A total of 43 patients had an adequate follow-up time of over 12 months. The majority of the patients (40/43 cases) were satisfied with the results. CONCLUSIONS: The authors believe that a footplate incision in aesthetic rhinoplasty is safe and can reliably achieve better results for Asian patients.

BACKGROUND: Negative-pressure wound therapy (NPWT) is believed to accelerate wound healing by altering wound microvascular blood flow. Although many studies using laser Doppler have found that NPWT increases perfusion, recent work using other modalities has demonstrated that perfusion is reduced. The purpose of this study was to investigate the influence of NPWT on tissue oxygenation of the foot, which is the most sensitive region of the body to ischemia. METHODS: Transcutaneous partial pressure of oxygen (TcpO2) was used to determine perfusion beneath NPWT dressings of 10 healthy feet. The sensor was placed on the tarso-metatarsal area of the foot and the NPWT dressing was placed above the sensor. TcpO2 was measured until it reached a steady plateau state. The readings obtained at the suction-on period were compared with the initial baseline (pre-suction) readings. RESULTS: TcpO2 decreased significantly immediately after applying NPWT, but gradually increased over time until reaching a steady plateau state. The decrease in TcpO2 from baseline to the steady state was 2.9 to 13.9 mm Hg (mean, 9.3+/-3.6 mm Hg; 13.5+/-5.8%; P<0.01). All feet reached a plateau within 20 to 65 minutes after suction was applied. CONCLUSIONS: NPWT significantly decrease tissue oxygenation of the foot by 2.9 to 13.9 mm Hg. NPWT should be used with caution on feet that do not have adequate tissue oxygenation for wound healing.

Soft tissue augmentation is a process of implanting tissues or materials to treat wrinkles or soft tissue defects in the body. Over the years, various materials have evolved to correct soft tissue defects, including a number of tissues and polymers. Autogenous dermis, autogenous fat, autogenous dermis-fat, allogenic dermis, synthetic implants, and fillers have been widely accepted for soft tissue augmentations. Tissue engineering technology has also been introduced and opened a new venue of opportunities in this field. In particular, a long-lasting filler consisting of hyaluronic acid filler and living human mesenchymal cells called "injectable tissue-engineered soft tissue" has been created and applied clinically, as this strategy has many advantages over conventional methods. Fibroblasts and adipose-derived stromal vascular fraction cells can be clinically used as injectable tissue-engineered soft tissue at present. In this review, information on the soft tissue augmentation method using the injectable tissue-engineered soft tissue is provided.

BACKGROUND: This anthropometric planning is devised for surgeons who assess the esthetic perspectives in Asian rhinoplasty and to provide an easy clinical method using two dimensional photograph. And specific planning in Asian secondary rhinoplasty are also depicted accordingly. METHOD AND DISCUSSION: In order to use a 2-dimensional digital photograph as a tool for the soft tissue cephalometric analysis (STCA) the surgeon can subjectively rotate the photograph to decide the ideal landmarks. Once this is done, consultation and planning begins. Complicated concepts can be simplified and adaptive ideal points needed in rhinoplasty can be determined according to the Asian concepts of beauty so that it will be used under a clinical setting. Initiation of planning starts by identifying the ideal Sellion and Subnasale, thus, determining the length of the nose. Determination of these two points is the foremost important step in planning. Thereafter, an ideal Tip forms naturally from the nasofrontal angle and the columellar-labial angle. Even with the well performed preoperative planning, the shortcomings in secondary Asian rhinoplasty, such as unexpected scar, may be totally different pitfalls to overcome. CONCLUSIONS: With two-dimensional digital photograph and simplified planning in STCA, planning ideal points will bring clarity to a relatively different planning process from western rhinoplasty for surgeons undertaking primary or secondary Asian rhinoplasty.

In covering wounds, efforts should include utilization of the safest and least invasive methods with goals of achieving optimal functional and cosmetic outcome. The recent development of advanced wound healing technology has triggered the use of cells to improve wound healing conditions. The purpose of this review is to provide information on clinically available cell-based treatment options for healing of acute and chronic wounds. Compared with a variety of conventional methods, such as skin grafts and local flaps, the cell therapy technique is simple, less time-consuming, and reduces the surgical burden for patients in the repair of acute wounds. Cell therapy has also been developed for chronic wound healing. By transplanting cells with an excellent wound healing capacity profile to chronic wounds, in which wound healing cannot be achieved successfully, attempts are made to convert the wound bed into the environment where maximum wound healing can be achieved. Fibroblasts, keratinocytes, adipose-derived stromal vascular fraction cells, bone marrow stem cells, and platelets have been used for wound healing in clinical practice. Some formulations are commercially available. To establish the cell therapy as a standard treatment, however, further research is needed.

BACKGROUND: Absorbable materials offer many advantages in the reconstruction of orbital walls; however, the possibility of postoperative enophthalmos after complete absorption cannot be excluded. We evaluated the postoperative results of absorbable mesh plates used as onlay implanting on the medial orbital wall to determine whether they are suitable for medial orbital wall reconstruction. METHODS: The study included 20 patients with medial orbital wall fractures who were followed up for more than 2 years postoperatively. We used absorbable mesh plates in all of the patients. We measured the following: the changes in the expanded orbital volume by comparing the preoperative and postoperative computed tomography (CT) scans and the degree of clinical enophthalmos. RESULTS: There were no major complications associated with the use of absorbable materials such as infection, migration, or extrusion of mesh plates during the long-term follow-up. The orbital volumetric changes between the preoperative and postoperative CT scans were not statistically significant. However, the expanded orbital volume was not related to the degree of clinical enophthalmos. CONCLUSIONS: The reconstructed orbital wall may provide supportive scar tissue to the orbital contents even after the absorbable materials have dissolved completely. Absorbable mesh plates could be another option for the reconstruction of the medial orbital wall.
