Zygomatic Fractures

Background: Zygoma is a very crucial component for the anteroposterior positioning of the midface and for the maintenance of facial contours. Zygomatic fractures are considered as the second most common type of facial fractures following nasal fractures. We have developed a new reduction technique called “lever,” which is based on the application of lifting force as an alternative to the methods in which the pulling force is applied. Patients: Over a 12-year period, 90 patients were treated with minimal access approach and 130 patients were treated with open reduction internal fixation (ORIF), using the lever technique. Results: In the follow-up period, no complications occurred in any of the patients who underwent minimal access approach. Miniplate removal operation was performed in 3 of the patients. Enophthalmos developed in one patient. Since 4 of the 7 suboptimal reduction patients did not experience any functional or cosmetic problems, no treatment was necessary and the remaining 3 patients underwent fat graft due to the presence of malar depression. Conclusion: This minimally invasive surgical procedure we have developed can be successfully used both in the minimal access approach and in ORIF, especially in delayed cases. We recommend this method due to the reasons that it is safe to conduct, easy to learn, fast to apply, simple to perform, and also economical to deploy.

This case report describes the treatment of peri-implantitis lesions through a minimally invasive surgical procedure using a peri-implant excisional procedure and access surgery (PEAS). The prosthesis was disconnected and the peri-implant granulation tissue removed following a peri-implant circular incision. Chemical debridement with hydrogen peroxide on a cotton ball and then mechanical debridement with a rotary round titanium brush and tufted brush with titanium bristles were conducted. The surgical intervention was effective in arresting the peri-implantitis. No further radiographic bone loss was observed over the 2-year follow-up period. This technique effectively cleans the contaminated implant surface, minimizes surgical morbidity and allows for prosthesis delivery on the day of surgery. However, further studies with a larger sample size are needed to identify the reliability and validity of this novel technique.

Background Lymphaticovenular anastomosis (LVA) is a minimally invasive surgical procedure used to treat lymphedema. Volumetric measurements and quality-of-life assessments are often performed to assess the effectiveness of LVA, but there is no method that provides information regarding postoperative morphological changes in lymphatic vessels and veins after LVA. Photoacoustic lymphangiography (PAL) is an optical imaging technique that visualizes the distribution of light-absorbing molecules, such as hemoglobin or indocyanine green (ICG), and provides three-dimensional images of superficial lymphatic vessels and the venous system simultaneously. In this study, we performed PAL in lymphedema patients before and after LVA and compared the images to evaluate the effect of LVA.Methods PAL was performed using the PAI-05 system in three patients (one man, two women) with lymphedema, including one primary case and two secondary cases, before LVA. ICG fluorescence lymphography was performed in all cases before PAL. Follow-up PAL was performed between 5 days and 5 months after LVA.Results PAL enabled the simultaneous visualization of clear lymphatic vessels that could not be accurately seen with ICG fluorescence lymphography and veins. We were also able to observe and analyze morphological changes such as the width and the number of lymphatic vessels and veins during the follow-up PAL after LVA.Conclusions By comparing preoperative and postoperative PAL images, it was possible to analyze the morphological changes in lymphatic vessels and veins that occurred after LVA. Our study suggests that PAL would be useful when assessing the effect of LVA surgery.

Objective: The aim of the study was to analyzed the efficacy and safety of a new minimally invasive surgical procedure using the Trans-Obturator-Tape with "outside-in" approach for treatment female stress urinary incontinence. Patients and Methods: 31 women with stress urinary incontinence (SUI) associated with urethral hypermobility, underwent the T.O.T. procedure (March 2010 to January 2011). 5 patients were previously operated for incontinence. Mean age was 59 years (37- 80). 10 patients were having mixed incontinence. A non-elastic, polypropylene tape was placed under the mid-urethra. The surgical placement technique utilises a trans-obturator percutaneous approach. All patients underwent post-operative clinical examination, coughstress test (full bladder), uroflowmetry, and post-voiding residual assessment. Results: Mean follow-up was 5 months (1-9). At 6 months follow-up 96,7% of the patients were completely cured. The overall peri-operative complication rate was 6,4% with no vascular, nerve or bowel injury. One patients (3,4%) had post-operative urinary retention. Conclusion: The present study confirms the results obtained by the instigator of the technique, E. Delorme, and allows us to consider T.O.T. as an effective and safe technique for the treatment of female stress urinary incontinence.

Main Components

This report presents the main components of a system for the model-based control of aerobic biological wastewater treatment plants. The crucial component is a model which is linked to the actual processes via several interfaces and which contains a unit which can immediately follow up the current process state. The simulation calculation of the model is based on data which are yielded by on-line measuring devices. If the sensors should fail at times, there are available a number of alternative concepts, some of which are based on the calculations of artificial neural networks or linear methods.

Substantial Morbidity

Bone is a frequent site of metastases in advanced cancers including lung, breast, prostate, kidney, or myeloma. Lesions are commonly located on the spine. Neoplastic invasion of the vertebral body can result in painful vertebral fractures, leading to disability and substantial morbidity. Percutaneous vertebroplasty is a minimally invasive surgical procedure used to treat spinal fractures due to osteolytic tumors. It could result in pain reduction or resolution in 80–90% of patients with fractures, and it improves stability. Although considered safe, vertebroplasty has been associated over the years with life-threatening complications. We have reported the case of a 55-year-old patient with lung adenocarcinoma, who underwent vertebroplasty for a pathological neoplastic fracture of L2. The procedure was complicated by a leak of cement into the systemic venous circulation, characterized by an 11-cm filament in the right heart chambers and multiple pulmonary emboli. To our knowledge, only one similar case was previously reported, involving an intracardiac cement filament longer than 10 cm. The data are scant, hence the importance of collecting and reporting possible complications about what is perceived as a rather safe procedure. The case highlights the need for a robust postprocedure imaging plan to detect complications, which can impact patients’ morbidity and survival.

The Difference

Lipofilling is a popular technique to treat volume loss in aging patients. The isolated adipose tissue is composed of adipocytes and stromal vascular fraction cells, which include adipose-derived stem cells (ASC). We hypothesize that the patient’s wrinkle severity scale (WSS) and patient’s satisfaction on the global aesthetic improvement scale (GAIS) can be improved after using concentrated lipoaspirate. Fourteen patients (54 years ± 11.09 years) with volume loss in the midface area underwent waterjet-assisted liposuction (Human Med AG, Schwerin, Germany). Fat was centrifuged in an ACP Double Syringe (Arthrex GmbH, Munich, Germany) using Rotofix 32A centrifuge (Andreas Hettich, GmbH & Co.KG, Tuttlingen, Germany). Homogenization was performed using the double syringe and a 1.4 mm female–female luerlock connector. After a second centrifugation, patients received periorbital (PO) and nasolabial (NL) lipografting. ASC count was performed after enzymatical digestion. Vitality of cells was assessed using a resazurin assay. During long-term follow up (12 months, n = 10), we found a high patient’s satisfaction (GAIS 1+/−0.52) and a good improvement of the WSS during short- and long-term follow-up. The ASC count of processed lipoaspirate was 2.1-fold higher than of unprocessed lipoaspirate (p < 0.001). The difference of ASC in sedimented and simply centrifuged lipoaspirate was also significant (p < 0.05). Facial rejuvenation with concentrated fat graft offers good results concerning objective aesthetic outcome and patient’s satisfaction.

Abstract Background This study aims to compare the graft uptake rate and hearing improvement of fat graft versus inlay butterfly tragal cartilage in the repair of perforations in chronic otitis media mucosal in adults. In this retrospective study, twenty-eight patients were included with small dry anteroinferior tympanic membrane perforations (less than 1/3 of the tympanic membrane). The age range was 18 to 44 years old. Myringoplasty was done under general anesthesia for 8 patients with a fat graft (FG) and 20 patients with inlay butterfly cartilage graft (IBCG). Six months postoperatively, a follow-up evaluation was done for successful graft uptake and hearing outcomes. Results The success rate of graft uptake in the first group (fat graft) was 6/8 cases (75%) while in the second group (IBCG) was 19/20 (95%) with no statistically significant difference (P = 0.0148). Also, there was no statistical difference between the two groups as regards postoperative ABG, improvement changes in ABG, and number of patients with improved hearing. Conclusions Inlay butterfly cartilage graft is a useful graft in repairing small tympanic membrane perforations as regard graft take and hearing outcomes.

The areas in which Stromal Vascular Fraction cells (SVFs) have been used include radiotherapy based tissue damage after mastectomy, breast augmentation, calvarial defects, Crohn’s fistulas, and damaged skeletal muscle. Currently, the authors present their experience using regenerative cell therapy in breast reconstruction. The goal of this study was to evaluate the safety and efficacy of the use of Engineered Fat Graft Enhanced with Adipose-derived Stromal Vascular Fraction cells (EF-e-A) in breast reconstruction. 121 patients that were affected by the outcomes of breast oncoplastic surgery were treated with EF-e-A, comparing the results with the control group (n = 50) treated with not enhanced fat graft (EF-ne-A). The preoperative evaluation included a complete clinical examination, a photographic assessment, biopsy, magnetic resonance (MRI) of the soft tissue, and ultrasound (US). Postoperative follow-up took place at two, seven, 15, 21, 36 weeks, and then annually. In 72.8% (n = 88) of breast reconstruction treated with EF-e-A, we observed a restoration of the breast contour and an increase of 12.8 mm in the three-dimensional volume after 12 weeks, which was only observed in 27.3% (n = 33) of patients in the control group that was treated with EF-ne-A. Transplanted fat tissue reabsorption was analyzed with instrumental MRI and US. Volumetric persistence in the study group was higher (70.8%) than that in the control group (41.4%) (p < 0.0001 vs. control group). The use of EF-e-A was safe and effective in this series of treated cases.
