BackgroundTemporal hollowing is inevitable after decompressive craniectomy. This complication affects self-perception and quality of life, and various techniques and materials have therefore been used to restore patients’ confidence. Autologous fat grafting in postoperative scar tissue has been considered challenging because of the hostile tissue environment. However, in this study, we demonstrate that autologous fat grafting can be a simple and safe treatment of choice, even for postoperative depressed temporal scar tissue.MethodsAutologous fat grafting was performed in 13 patients from 2011 to 2016. Fat was harvested according to Coleman’s strategy, using a tumescent technique. Patient-reported outcomes were collected preoperatively and at 1-month and 1-year follow-ups. Photographs were taken at each visit.ResultsThe thighs were the donor site in all cases for the first procedure. The median final volume of harvested fat was 29.4 mL (interquartile range [IQR], 24.0–32.8 mL). The median final volume of fat transferred into the temporal area was 4.9 mL on the right side (IQR, 2.5–7.1 mL) and 4.6 mL on the left side (IQR, 3.7–5.9 mL). There were no major complications. The patient-reported outcomes showed significantly improved self-perceptions at 1 month and at 1 year.ConclusionsDespite concerns about the survival of grafted fat in scar tissue, we advise autologous fat grafting for patients with temporal hollowing resulting from a previous craniectomy.

Background: Many wound assessment systems including the Wagner classification and University of Texas (UT) grading system have been previously described. The authors of this study applied the DIRECT (Debridement of necrosis, Infection control, Revascularization, Exudate control, Chronicity, and Top surface) wound coding system for initial assessment of diabetic foot ulcers (DFUs) to predict limb salvage and prognosis.<br/>Methods: From January 2016 to February 2020, a total of 169 first-time DFU patients were retrospectively evaluated using the DIRECT wound coding assessment system. DFUs were followed up for at least 6 months, and scores in each component of the coding system according to final limb status were statistically evaluated. The coding assessment’s ability to predict major amputation was compared to those of the Wagner classification and the UT grading system.<br/>Results: Subjects were divided into complete healing (n=80, 47.3%), not healed (n=71, 42%), and amputation (n=18, 10.7%) groups. The mean values of each component of DIRECT assessment for the complete healing/amputation groups were D 0.86/1.56 (P<0.001), I 0.46/0.89 (P=0.001), R 0.65/0.94 (P=0.014), E 1.15/1.56 (P=0.049), C 0.69/0.89 (P=0.086), T 0.53/0.72 (P=0.13) and the sum was 3.140/4.741 (P<0.001). The area under the receiver operating characteristic curve of the DIRECT, Wagner, and UT grading systems was 0.722, 0.603, and 0.663, respectively.<br/>Conclusion: The DIRECT coding system shows a greater association with prediction of amputation or complete healing, compared with the Wagner and UT wound classification systems. This more accurate wound assessment system will be helpful in predicting prognosis and planning treatments.

Background: This study was conducted to determine the relationship between third molar (M3) and mandibular fracture. Methods: Patients with unilateral mandibular angle or condyle fractures between 2008 and 2018 were evaluated retrospectively. Medical records were reviewed regarding the location of fractures, and panoramic radiographs were reviewed to discern the presence and position of ipsilateral mandibular third molars (M3). We measured the bony area of the mandibular angle (area A) and the bony area occupied by the M3 (area B) to calculate the true mandibular angle bony area ratio (area A-B/area A × 100). Results: The study consisted of 129 patients, of which 60 (46.5%) had angle fractures and 69 (53.5%) had condyle fractures. The risk of angle fracture was higher in the presence of M3 (odds ratio [OR], 2.2; p < 0.05) and the risk of condyle fracture was lower in the presence of M3 (OR, 0.45; p < 0.05), than in the absence of M3. The risk of angle fracture was higher in the presence of an impacted M3 (OR, 0.3; p < 0.001) and the risk of condyle fracture was lower in the presence of an impacted M3 (OR, 3.32; p < 0.001), than in the presence of a fully erupted M3. True mandibular angle bony area ratio was significantly lower in the angle fractures than in the condyle fractures (p = 0.003). Conclusion: Angle fractures had significantly lower true mandibular angle bony area ratios than condyle fractures. True mandibular angle bony area ratio, a simple and inexpensive method, could be an option to predict the mandibular fracture patterns.

Despite greater anterior overcorrection, relapse occurred owing to scar tissue retraction and mandibular compensatory hypertrophy. The results suggest that the younger the patient, the more likely relapse will occur.

Frontal sinus fractures, particularly anterior sinus fractures, are relatively common facial fractures. Many agree on the general principles of frontal fracture management; however, the optimal methods of reduction are controversial. The subbrow approach enables accurate reduction and internal fixation of the fractures in the anterior table of the frontal sinus by allowing direct visualization of the fracture. Given the surgical success in reduction and rigid fixation, patient satisfaction, and aesthetic benefits, the transcutaneous approach through a subbrow incision is superior to other reduction techniques used in the management of an anterior table frontal sinus fracture.
