Endoscopic surgical operations of the larynx have many desirable features, including the conservative nature of these procedures, plus the ability to produce surgical changes predictable from the onset. For several years the direct lateralization of the vocal ligament after the removal of a preassessed amount of thyroarytenoid muscle appeared to be the simplest and most accurate surgical procedure. The resection of this wedge of muscle was easily performed with laryngeal microcautery. Posterior cicatricial webs can be easily removed with this instrument. Simple suturing techniques are also described, including the practicability of using padded buttons plus lead fishing sinkers to adjust the tension and secure these sutures on the surface of the neck. So far 16 patients have been rehabilitated using this technique, including 6 patients with posterior commissure webs. These anatomical techniques should be considered because of their obvious simplicity.

Background: Motivation and necessity to adopt minimally invasive therapies in the field of spinal regenerative medicine is increasing. Autologous platelet-rich plasma (PRP) therapy has recently been used as an effective technological and biological approach to tissue repair and has shown to improve multiple conditions including back pain and degenerative disc pathology. In addition, it is well established that the anatomic elements of the spinal system affected by degenerative pathology include the intervertebral disc (IVD) and vertebral subchondral bone (VSB), which play a crucial role in maintaining a healthy spinal column. Both elements are the target of a novel biological approach to the treatment of low back pain. Methods: A novel minimally invasive regenerative therapeutic approach is presented herein with a protocol based on combining vertebral intraosseous (VIO) and intradiscal (ID) infiltrations of plasma rich in growth factors (PRGF-Endoret), a type of leukocyte-free PRP, for the treatment of disc degeneration pathology. Results: We describe a novel technique applied in a patient treated for IVD degeneration and VSB damage, showing significant improvement on magnetic resonance imaging, including partial regression of protruded disc and significant resorption of intravertebral herniations (Schmörl's nodes), after PRGF therapy. Conclusions: To the best of our knowledge, we present the first reported case description of the utilization of VIO and ID PRP infiltrations to treat protruded discs and intravertebral herniations with a successful clinical outcome.

Context:Low back pain (LBP) is a complex and disabling condition, and its treatment becomes a challenge.Aims:The aim of our study was to assess the clinical outcome of plasma rich in growth factors (PRGF-Endoret) infiltrations (one intradiscal, one intra-articular facet, and one transforaminal epidural injection) under fluoroscopic guidance-control in patients with chronic LBP. PRGF-Endoret which has been shown to be an efficient treatment to reduce joint pain.Settings and Design:The study was designed as an observational retrospective pilot study. Eighty-six patients with a history of chronic LBP and degenerative disease of the lumbar spine who met inclusion and exclusion criteria were recruited between December 2010 and January 2012.Subjects and Methods:One intradiscal, one intra-articular facet, and one transforaminal epidural injection of PRGF-Endoret under fluoroscopic guidance-control were carried out in 86 patients with chronic LBP in the operating theater setting.Statistical Analysis Used:Descriptive statistics were performed using absolute and relative frequency distributions for qualitative variables and mean values and standard deviations for quantitative variables. The nonparametric Friedman statistical test was used to determine the possible differences between baseline and different follow-up time points on pain reduction after treatment.Results:Pain assessment was determined using a visual analog scale (VAS) at the first visit before (baseline) and after the procedure at 1, 3, and 6 months. The pain reduction after the PRGF-Endoret injections showed a statistically significant drop from 8.4 ± 1.1 before the treatment to 4 ± 2.6, 1.7 ± 2.3, and 0.8 ± 1.7 at 1, 3, and 6 months after the treatment, respectively, with respect to all the time evaluations (P < 0.0001) except for the pain reduction between the 3rd and 6th month whose signification was lower (P < 0.05). The analysis of the VAS over time showed that at the end point of the study (6 months), 91% of patients showed an excellent score, 8.1% showed a moderate improvement, and 1.2% were in the inefficient score.Conclusions:Fluoroscopy-guided infiltrations of intervertebral discs and facet joints with PRGF in patients with chronic LBP resulted in significant pain reduction assessed by VAS.
