SummaryFor disc herniations the use of open surgical approaches is reduced since new percutaneous methods allowing shrinkage of the disc and improvement of the radicular function are gaining interest. Studies on the spontaneous disappearance of disc fragments have demonstrated autoimmune responses with a chronic inflammatory reaction. Also radicular pain has been shown to be mostly due to biochemical mechanisms [10]. Researchers in di¤erent fields surprisingly noticed that a brief, calculated, oxidative stress by ozone administration may correct a persistent imbalance due to excessive, chronic oxidative injury [4]. Oxygen-ozone gas injection in painful patients has a dramatic e¤ect on clinical symptoms. On these bases the intradiscal injection of oxygen-ozone gas has been conceived [1,7,9]. We report the treatment on a series of patients a¤ected by cervical disc pathology, treated by intradiscal injection of oxygen-ozone gas mixture. The e¤ects both on pain and on radicular dysfunction are impressive. The morphological e¤ect of the treatment was also evaluated by pathological examination.

Background Autologous fat grafting (AFG) for primary aesthetic breast augmentation has grown in popularity over recent years but patient satisfaction has never been objectively evaluated. Objectives The aim of the present study was to use the standardized BREAST-Q questionnaire to evaluate satisfaction in patients who had received primary aesthetic breast augmentation with AFG alone. Methods All recipients of primary aesthetic breast augmentation by AFG performed between 2013 and 2017 in our plastic surgery department were included. The primary endpoint was assessment of patient satisfaction with the standardized breast augmentation BREAST-Q questionnaire. Three additional questionnaires were used to evaluate patient and surgeon satisfaction. Results In total, 42 patients (84 breasts) underwent breast augmentation by AFG. Mean patient age was 34 years (range, 23-53 years). The mean volume of reinjected fat was 312.2 mL per breast (range, 130-480 mL). We observed significant improvement in all BREAST-Q postoperative items (excluding physical well-being) with a mean increase of 39 points (95% confidence interval: 28.97, 49.03; P < 0.001) regarding patient satisfaction with breasts. Overall, 82% of patients were satisfied with the result of their liposuction. Minor complications were encountered in 6 of our patients (14%). Conclusions Breast augmentation by AFG enhances patient satisfaction as measured by the BREAST-Q. This procedure has a high satisfaction rate and improves quality of life. Breast augmentation by AFG is a valid surgical option for moderate breast augmentation but is not an alternative to implants in large breast augmentation. Level of Evidence: 4
