The ideal surgical solution to reconstruct the temporomandibular joint (TMJ) disc after it has been removed has remained elusive. The major obstacle has been identifying a durable biocompatible material that will provide for restoration of TMJ function. The present study evaluated the outcomes of the interpositional implantation of a cryopreserved viable osteochondral allograft (CVOCA) combined with a viable cryopreserved umbilical cord tissue (vCUT) allograft after TMJ discectomy in patients with internal derangement and/or degenerative joint disease (DJD).We implemented a retrospective case series study and enrolled patients with DJD or disc displacement diagnosed using the Diagnostic Criteria of Temporomandibular Disorders, who had undergone interpositional CVOCA and vCUT implantation after TMJ discectomy. The primary outcome variable was pain, measured using a visual analog scale (VAS). The secondary outcomes variables included maximal incisal opening (MIO) and Glasgow Benefit Inventory (GBI) general subscale scores. The primary analysis compared the preoperative measures with those at the last follow-up visit. Descriptive and analytic statistics were computed to summarize the sample's characteristics and assess the pre- and postoperative differences.The study sample included 9 patients with a mean age of 36 years, and 44% were men. The VAS scores had decreased significantly from 9.0 ± 2.0 to 3.0 ± 3.0 postoperatively (P = .001). The MIO had increased from 31 ± 5 to 36 ± 5 mm (P = .178). The average GBI general subscale score of 13 ± 46 for the 9 patients showed a trend toward improved quality of life and patient satisfaction with the surgery. The median postoperative follow-up at the time of our report was 15 months (interquartile range, 10; range, 2 to 27) without treatment-related complications.The reported outcomes suggest that the interpositional implantation of CVOCA and vCUT after TMJ discectomy could be a solution for reducing TMJ-related pain and restoring TMJ function. Longer follow-up and prospective multicenter studies are warranted.
Higher concentrations of fraction of inspired oxygen (FIO2) have been shown to be associated with lower risk for surgical site infection in multiple studies outside the domain of orthopedic surgery. We evaluated the efficacy of high FIO2 administered during the perioperative period to reduce the rate of surgical site infection after open fixation of lower-extremity fractures at high risk of infection.We conducted a randomized controlled, parallel design, double-blind study. Patients sustaining high-energy tibial plateau, tibial pilon, and calcaneus fractures treated in a staged fashion were selected for enrollment because these injuries are associated with high risk of infection. The study population included 222 patients with 235 fractures. Consenting patients were randomized by random number sequence to either the treatment or the control group. Treatment group patients received 80% FIO2 intraoperatively and for 2 hours afterward. Control group patients received 30% FIO2 during the same period. Surgeons, patients, and personnel who performed wound assessments were blinded to group assignment. The primary outcome measure was surgical site infection as defined by the Centers for Disease Control criteria for postoperative wound infection.The overall rates of postoperative surgical site infection were 12% (14 of 119 fractures) in the treatment group and 16% (19 of 116 fractures) in the control group (p = 0.31). Multivariate analysis, accounting for risk factors for infection, yielded the closest to a statistically significant reduction in the odds of infection with treatment (odds ratio, 0.54; p = 0.17). No treatment-associated events were observed.Use of a high concentration of FIO2 during the perioperative period is safe and shows a trend toward reduction of surgical site infection in patients undergoing open operative fixation of high-energy traumatic lower-extremity fractures. Further study in a larger patient population is indicated.Therapeutic study, level III.
In Brief BACKGROUND Current infection risk scores are not designed to predict the likelihood of surgical site infection after orthopedic fracture surgery. We hypothesized that the National Nosocomial Infections Surveillance (NNIS) System and the Study on the Efficacy of Nosocomial Infection Control (SENIC) scores are not predictive of infection after orthopedic fracture surgery and that risk factors for infection can be identified and a new score created (Emerg Infect Dis. 2003;9:196–203). METHODS We conducted a secondary analysis of data from a trial involving internal fixation of 235 tibial plateau, pilon, and calcaneus fractures treated between 2007 and 2010 at a Level I trauma center. The predictive value of the NNIS System and SENIC scores was evaluated based on areas under the receiver operating characteristic (ROC) curve. Bivariate and multiple logistic regression analyses were used to build an improved prediction model, creating the Risk of Infection in Orthopedic Trauma Surgery (RIOTS) score. The predictive value of the RIOTS score was evaluated via the ROC curve. RESULTS NNIS System and SENIC scores were not predictive of surgical site infection after orthopedic fracture surgery. In our final regression model, the relative odds of infection among patients with AO [Arbeitsgemeinschaft für Osteosynthesefragen] type C3 or Sanders type 4 fractures compared with fractures of lower classification was 5.40. American Society of Anesthesiologists class 3 or higher and body mass index less than 30 were also predictive of infection, with odds ratios of 2.87 and 3.49, respectively. The area under the ROC curve for the RIOTS score was 0.75, significantly higher than the areas for the NNIS System and SENIC scores. CONCLUSION The NNIS System and SENIC scores were not useful in predicting the risk of infection after fixation of fractures. We propose a new score that incorporates fracture classification, American Society of Anesthesiologists classification, and body mass index as predictors of infection.

Obstructive sleep apnea (OSA) is a prevalent condition that affects people of all ages. Surgical management has improved with growing understanding of OSA pathophysiology, new methods of airway phenotyping and precision in operative techniques. The classic Stanford phased approach serves as a foundation for the updated algorithm, which places surgery on a continuum with medical and dental care. The last 40 years have seen a burgeoning of effort focused on individual surgical or dental procedural success rates. What lies ahead should be a focus on improving overall treatment success, usually achievable only with multimodal interventions. The goal of treatment success for the OSA patient will foster collaboration across disciplines.
Background: Reconstruction of full thickness mandibular defects with disarticulation due to ORNJ has traditionally been accomplished using vascularized free fibula flaps (FFF). But not all patients are candidates for FFF. A two-staged protocol (SPR) was developed taking into account the challenges of the surgical site and comorbidities of the patient utilizing custom prosthetics.
Methods: This study retrospectively analyzed 16 patients (13 males, 3 females) who developed stage III ORNJ subsequent to radiation and molar extraction (FFF n=4, SPR n=12). Postoperative surgical complications, maximal incisal opening (MIO), Pain Visual Analog Scale (VAS) at the different end points for the SPR and FFF group were analyzed.
Results: All patients demonstrated decrease in pain and increased mouth opening. Comparing Stage 1 SPR and FFF patients, there was a significant difference in pain, but not in function (1.89 ± 1.05 vs 0.25 ± 0.5, p 0.20). After completion of the second stage surgery, there were significant differences in function, but not in pain in comparison to FFF patients (24.75 ± 1.26 vs 36.5 ± 8.37, p 0.779).
Conclusion: Reconstruction of the temporomandibular joint with a custom prosthesis contributes to the significant improvement in function in the stage 1 SPR and in pain in stage 2 SPR versus the FFF.
