BACKGROUND: Temporal 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. METHODS: Autologous 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. RESULTS: The 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. CONCLUSIONS: Despite 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: This study was conducted to determine the effect of the distributional relationship between dental roots and the mandibular bone on single mandibular bone fractures, which are common craniofacial fractures. METHODS: This was a retrospective, single-center study in Seoul, Korea. Patients with single mandibular fractures in the symphysis, parasymphysis, body, and angle area, with tooth structure involvement were included. The control group included patients with simple, bone-level lacerations without fractures. In total, 94 patients (72 males and 22 females) were included in the treatment group, and 125 (71 males and 54 females) were included in the control group. The height of the mandibular bone and the dental root were measured with panoramic radiography. The central incisor represented the symphysis area, the canine represented the parasymphysis area, the first molar represented the body area, and the second molar represented the angle area. RESULTS: In the treatment group, symphysis fractures occurred in 16 patients (17%), parasymphysis fractures in 36 patients (38%), body fractures in 17 patients (18%), and angle fractures in 25 patients (27%). The ratios of the dental roots to the total height of the mandibular bone in the treatment group were 30.35%, 39.75%, 39.53%, and 36.27% for symphysis, parasymphysis, body, and angle areas, respectively, whereas in the control group, they were 27.73%, 39.70%, 36.76%, and 35.48%. The ratios of the treatment group were significantly higher than those of the control group. CONCLUSION: The results show that the higher ratio of the dental root to the height of the mandibular bone increases the fracture risk.

BACKGROUND: Platelet-rich plasma (PRP) has been advocated as a way to introduce increased concentrations of growth factors and other bioactive molecules to injured tissues in an attempt to optimize the local healing environment. Many methods for PRP preparation have been introduced. Despite variations in the volume of whole blood taken and the efficacy of the platelet concentration, the main objective of PRP preparation is to obtain sufficient platelet concentration in the finally processed autologous plasma. We have been making our own internal primitive PRP preparation, which is safe and aseptic, using simple tubes and a centrifugal separator at the outpatient department base. METHODS: Twenty cc of whole blood was collected and 10 cc of blood was added to each of two bottles, followed by addition of 1.5 cc adenosine-citrate-dextrose-acid solution to each bottle. Then, centrifugal separation was performed at 4,000 RPM for 15 minutes. Then, the buffy coat layer was aspirated using a 10 cc syringe equipped with a spinal needle. Platelet activation was initiated by addition of CaCl2 and botropase. RESULTS: We were successful in attaining PRP, which was three folds and six folds concentrated compared with the initial platelet count of whole blood. CONCLUSIONS: Our protocol is economical and only requires a few simple procedures for preparation of PRP. We expect the protocol to be applied to clinical trials without significant cost of time and money.
