Effect of Flap Selection on the Postoperative Success of Sacral Pressure Injuries: A Retrospective Analysis.

INTRODUCTION: Pressure injuries (PIs) continue to be a substantial problem and burden for the present-day health care system and are the leading cause of chronic wounds worldwide. There is no current consensus on the long-term results of the use of flaps in sacral PI reconstruction and optimal flap choice. OBJECTIVE: This study aimed to evaluate whether flap selection influences postoperative results in sacral PI reconstruction. MATERIALS AND METHODS: Patients who underwent surgery for PIs in the authors' clinic between 2002 and 2016 were retrospectively analyzed. A total of 63 patients with stage 3/stage 4 sacral PIs and who underwent reconstruction with fasciocutaneous (FC) flaps (group 1), musculocutaneous (MC) flaps (group 2), or perforator (P) flaps (group 3) were included in the study. The mean duration of the follow-up period was 14.4 months, and patients were evaluated in terms of their demographic data, length of hospital stay, complications, and recurrence. RESULTS: The mean age, sex distribution, and ambulatory status were similar between the groups. In group 2 (MC), the mean length of hospital stay and mean drain removal time were significantly longer. The mean daily drainage amount was significantly higher in group 2 (MC) than in the other groups, and long-term relapses were less frequently observed in group 3 (P). A significant difference was observed between groups 2 (FC) and 3 (MC) in terms of wound dehiscence. The authors determined that P flaps were associated with a reduced mean length of hospital stay and daily drainage. CONCLUSIONS: For these patients, P flaps appear to be the optimal flap choice for sacral area reconstruction. However, new prospective randomized studies are needed to support these findings.

The Effect of Minocycline on Fat Graft Survival and Apoptotic Pathway.

Variable absorption rate is one of the biggest problems of fat grafting and one of the most important causes of fat graft volume loss is apoptosis. Minocycline is a tetracycline derivative and besides its antibacterial capacity, it has been widely using for anti-apoptotic effects. This study was designed to investigate the effect of minocycline on fat graft survival and adipocyte apoptosis. A total of two main and eight subgroups were designed and a total of 48 experimental animals, 6 in each group, were used. Fat grafts are obtained from Wistar albino rats and implanted to dorsal area of rats. Local and systemic minocycline was applied in the study groups. On the 9th day, apoptotic cells were detected by the terminal deoxynucleotidyl transferase dUTP nick end labeling method and on the 90th day morphologic characteristics and viability of adipocytes were evaluated using histologic and immunohistochemical methods and statistically compared. This study revealed that the fat grafts were bigger, and they kept their structures better and they were more vascular in the minocycline groups and apoptosis was significantly lower in the minocycline groups. The authors demonstrated that minocycline increases fat graft survival and statistical improvement in apoptosis inhibition via using minocycline therapy has been shown.

Defining a New Variable That May Impact Long-term Postoperative Nasal Tip Support: The Biomechanical Properties of the Columellar Strut Graft.

BACKGROUND: Although columellar strut grafts (CSGs) are considered among the fundamental steps for providing nasal tip support, a downward rotation of the nasal tip in patients with strut grafts can still be encountered. Patient-related factors such as nasal skin thickness can allow the plastic surgeon to anticipate certain drawbacks that can be encountered in the healing phase, but patient-based differences of nasal cartilage and the resulting impact have yet to be investigated. The purpose of this study was to evaluate the effect of the biomechanical properties of CSGs on late postoperative nasal tip position and support. METHODS: The study was undertaken with the participation of 20 patients undergoing closed-technique primary rhinoplasty with CSGs. Each cartilage specimen was biomechanically analyzed to calculate the modulus of elasticity. Preoperative and postoperative images were obtained to determine nasal tip position and rotation with quantitative measurements. Postoperative 3- and 12-month measurements were evaluated according to their relationship with the elasticity modulus of the utilized cartilages. RESULTS: The evaluation demonstrated that the elasticity modulus can impact the long-term support of the nasolabial angle in which an increase in the coefficient of elasticity can result in a decrease in long-term nasal tip support. CONCLUSION: The results of the study reveal a new objective variable that can impact nasal tip dynamics and patient-related differences following rhinoplasty. This study not only brings forth a different perspective in the evaluation of nasal tip dynamics but can also provide data for determining ideal values for cartilage prefabrication.

The Efficacy of Vibration Anesthesia on Reducing Pain Levels During Lip Augmentation: Worth the Buzz?

Background: Lip augmentation procedures have increased drastically in the last years as patients seek to enhance the shape and size of their lips with dermal fillers. One of the main concerns faced with these procedures is the pain inflicted through injections. On the other hand, many different techniques have been introduced for the reduction of pain while performing office-based minimal invasive procedures. Objectives: This study aims to determine the analgesic effect of vibration anesthesia during lip augmentation procedures and to evaluate its overall effect on the comfort of patients. Methods: A split-lip study was designed in a randomized fashion for 25 lip augmentation patients who received hyaluronic acid fillers with or without with a concurrent vibration stimulus on either half of their lips. Patients were asked to score the pain that they felt during lip injections on a scale from 0 to 10 (0 being no pain and 10 being the worst pain ever felt) for either lip half. The pain scores were then analyzed for significance. Results: The overall pain score on the vibration-assisted side was 3.82 ± 1.73 while the pain score for the side with no vibration was 5.6 ± 1.76 (P < 0.001). Twenty-three patients (92%) felt less pain with the addition of vibration while, interestingly, 2 patients (8%) stated that they felt an increase in pain levels on the vibration-treated side. Conclusions: Vibration devices can be a safe and effective tool for lowering pain levels in patients undergoing lip augmentation with hyaluronic acid fillers. Level of Evidence: 2.

A new option for the reconstruction of orbital floor defects with heterologous cortical bone.

BACKGROUND: The orbital floor is one of the most frequently injured areas of the maxillofacial skeleton during facial trauma. A retrospective analysis of patients who have undergone treatment of orbital floor fractures with heterologous cortical bone is presented. METHODS: This retrospective study was carried out with 21 patients over a period of 4 years between 2010 and 2014. All patients with a traumatic orbital floor defect who underwent reconstruction with heterologous cortical bone were included. The operations were carried out under general anesthesia for all patients. A subciliary incision was used in 20 patients and an infraorbital approach was used in one patient. All patients underwent follow-up examinations clinically as well as radiologically, at 1, 3, 6 and 12 months postoperatively. Computed tomographic scans were taken at the postoperative 6th month, and at the first postoperative year if needed. RESULTS: Preoperatively, the physical examination revealed diplopia in 17 patients (80.9%), gaze restriction in 14 patients (66.6%), enophthalmos in six patients (28.5%), and infraorbital nerve paresthesia in two patients (9.5%). None of the patients showed impaired visual acuity preoperatively or postoperatively. Diplopia and gaze restriction resolved postoperatively in all of the patients. All patients had a negative intraoperative forced duction test demonstrating free globe movement. Enophthalmos showed complete resolution in the postoperative period. In one of the two patients with preoperative infraorbital nerve paresthesia, this resolved at the postoperative fifth month. Scleral show appeared in six patients but resolved completely within 3-8 weeks with massage. There was no graft extrusion, resorption or displacement during the follow-up period. CONCLUSIONS: Tecnoss Semi Soft Lamina is a good alternative for the reconstruction of blowout fractures due to its plasticity and biocompatible structure. Without donor site morbidity, it is a safe and appropriate heterologous bone graft material for maxillofacial applications such as orbital floor reconstruction. We cannot recommend its use for near-total, wide orbital floor defects as it may not provide enough support in such circumstances.

A Social Evaluation of Perception on Body Contouring Surgery by Turkish Male Aesthetic Surgery Patients.

Although aesthetic procedures are known to have a higher impact on women, men are becoming more inclined toward such procedures since the last decade. To determine the reason behind the increase in demand for male aesthetic procedures and to learn about the expectations and inquietude related to body contouring surgery, a prospective questionnaire study was conducted on 200 Turkish males from January 1, 2011-May 31, 2012. Demographic information, previous aesthetic procedures and thoughts on body contouring procedures with given reasons were questioned. The results of the study showed that 53 % of all participants considered undergoing body contouring surgery with the given reason that they believed their current body structure required it. For those who did not consider contouring operations, 92.5 % said they felt that they did not need such a procedure. The results of the statistical analysis showed that BMI was a significant factor in the decision making process for wanting to undergo body contouring procedures. The results of the study showed that men's consideration for aesthetic operations depends mainly on necessity and that the most considered region was the abdominal zone in regard to contouring. We can conclude that men are becoming more interested in body contouring operations and therefore different surgical procedures should be refined and re-defined according to the expectations of this new patient group.

The Effect of Microneedle Thickness on Pain During Minimally Invasive Facial Procedures: A Clinical Study.

BACKGROUND: Minimally invasive procedures are becoming increasingly popular because they require minimal downtime and are effective for achieving a more youthful appearance. The choice of needle for minimally invasive procedures can be a major factor in the patient's comfort level, which in turn affects the physician's comfort level. OBJECTIVES: In this comparative study, the authors assessed levels of pain and bruising after participants were injected with 30-gauge or 33-gauge (G) microneedles, which are commonly used for minimally invasive injection procedures. METHODS: Twenty healthy volunteers were recruited for this prospective study. Eight injection points (4 on each side of the face) were determined for each patient. All participants received injections of saline with both microneedles in a randomized, blinded fashion. Levels of pain and bruising were assessed and analyzed for significance. RESULTS: The highest level of pain was in the malar region, and the lowest level was in the glabella. Although all pain scores were lower for the 33-G microneedle, the difference was significant only for the forehead. Because most minimally invasive procedures require multiple injections during the same sitting, the overall procedure was evaluated as well. Assessment of the multiple-injection process demonstrated a significant difference in pain level, favoring the 33-G needle. Although the difference in bruising was not statistically significant between the 2 needles, the degree of bruising was lower with the 33-G needle. CONCLUSIONS: For procedures that involve multiple injections to the face (such as mesotherapy and injection of botulinum toxin A), thinner needles result in less pain, making the overall experience more comfortable for the patient and the physician.
