BACKGROUND AND OBJECTIVES: Endoscopic transnasal surgery offers a minimally invasive alternative to transcranial approaches for accessing midline skull base lesions involving the petrous apex and petroclival region. However, lateral access, particularly behind the petrous internal carotid artery (ICA), remains limited. The contralateral transmaxillary (CTM) approach provides a more direct surgical trajectory, more parallel to the petrous ICA. Yet, lateral access through this approach can be restricted by anatomic barriers, including the pterygoid process and lateral buttress of the maxillary sinus. We aimed to evaluate the contralateral transmaxillary-transpterygoid (CTMP) approach, with and without the lateral buttress removal (CTMP-LBR), to determine whether these modifications could enhance surgical access to the petroclival region. METHODS: Ten sides from 5 formalin-fixed, latex-injected cadaveric specimens were dissected to compare CTM, CTMP, and CTMP-LBR approaches. Petrous bone drilling was directed posterolaterally behind the petrous ICA toward the region medial to the cochlea. In addition, 30 sides from computed tomography angiography scans were analyzed to obtain radiographic measurements for each approach. RESULTS: Compared with CTM, both CTMP and CTMP-LBR significantly increased access for retrocarotid petrous bone drilling ( P < .001) and yielded a wider surgical angle relative to midline ( P < .001), in both cadaveric and radiographic analyses. In dissections, 20% of sides required CTM only, 50% benefited from CTMP, and 30% required CTMP-LBR to achieve adequate lateral access. Radiographic analysis revealed that CTMP required a median of 4 mm of pterygoid drilling, whereas CTMP-LBR required 9 mm and enabled a trajectory parallel to the petrous ICA with only 11 mm of soft tissue displacement. Patients with smaller angles between the petrous ICA and the horizontal plane were significantly more likely to benefit from CTMP over CTM ( P = .005). CONCLUSION: Modification of the CTM approach with pterygoid drilling and optional LBR improves retrocarotid access. Preoperative evaluation of the petrous ICA angle may help optimize patient-specific planning in endoscopic petroclival surgery.

Background Although regional anesthesia (RA) is associated with improved pain control, reduced opioid use, and accelerated recovery after arthroplasty, racial and geographic differences have been identified in hip and knee arthroplasty, with limited data for shoulder and ankle arthroplasty. We examined differences in RA utilization for shoulder, hip, knee, and ankle arthroplasty, based on patient-level and hospital-level characteristics. Methods Using the National Inpatient Sample, we conducted a cross-sectional study of adults who underwent shoulder, hip, knee, and ankle arthroplasties from 2016 to 2020. RA was defined using procedure codes for neuraxial anesthesia and peripheral nerve blocks. Weighted descriptive statistics summarized RA utilization and compared patient-level and hospital-level characteristics using standardized mean differences (SMDs), with ≥0.10 indicating meaningful differences. Results We identified 1132 011 unweighted admissions, representing approximately 5.7 million weighted arthroplasties. RA was used in 7.0% of cases. RA utilization varied by procedure type, with the highest rates in shoulder (11.4%) and ankle arthroplasty (11.4%), followed by knee (9.1%) and hip arthroplasty (2.4%). Variation in RA utilization was observed in ankle arthroplasty based on race (SMD=0.11) and primary payer (SMD=0.12). RA use also varied by hospital size for shoulder (SMD=0.13), hip (SMD=0.29), and knee arthroplasty (SMD=0.22), by hospital location and teaching status for shoulder (SMD=0.17), hip (SMD=0.18), knee (SMD=0.19), and ankle arthroplasty (SMD=0.12), and by geographic region for shoulder (SMD=0.26), hip (SMD=0.45), knee (SMD=0.24), and ankle arthroplasty (SMD=0.17). Conclusions There is notable variation in RA use for inpatient arthroplasty across hospitals and geographic regions, with limited variation based on patient characteristics. These findings highlight the presence of system-level variation in RA use and underscore the need for further research to better understand the drivers of these patterns.

In 2024, the Journal of Wound Care ( JWC ) published best-practice guidance on wound debridement. This introduced the concept of integral debridement, defined as the combined use of complementary debridement methods on the same wound to optimise healing outcomes. This typically involves combining less invasive approaches, such as autolytic debridement, with more active adjunctive methods, including mechanical and/or sharp debridement. In 2026, JWC convened an expert panel to explore how this concept can be effectively implemented in non-specialist settings. The panel concluded that debridement is most effective when applied repeatedly throughout the healing process and introduced the concept of continuous integral debridement (CID), a cyclical four-step approach comprising cleanse, debride, cleanse and dress (CDCD). The panel propose that, when performed regularly, this will help disrupt microbial and non-microbial barriers to healing and maintain a clean wound environment. The panel consider that CID is compatible with established frameworks, such as TIME/TIMERS and the International Wound Infection Institute wound infection continuum, and complements antibiofilm strategies, including Wound Hygiene. This document provides practical guidance for integrating CID into routine wound care across all clinical settings, including recommendations on cleansing solutions, debridement methods and dressing selection, with the aim of supporting evidence-based practice and improving patient outcomes.
