OBJECTIVEThere are numerous treatment strategies in the management for large vestibular schwannomas, including resection only, staged resections, resections followed by radiosurgery, and radiosurgery only. Recent evidence has pointed toward maximal resection as being the optimum strategy to prevent tumor recurrence; however, durable tumor control through aggressive resection has been shown to occur at the expense of facial nerve function and to risk other approach-related complications. Through a retrospective analysis of their single-institution series of keyhole neurosurgical approaches for large vestibular schwannomas, the authors aim to report and justify key techniques to maximize tumor resection and reduce surgical morbidity.METHODSA retrospective chart review was performed at the Centre for Minimally Invasive Neurosurgery. All patients who had undergone a keyhole retrosigmoid approach for the resection of large vestibular schwannomas, defined as having a tumor diameter of ≥ 3.0 cm, were included in this review. Patient demographics, preoperative cranial nerve status, perioperative data, and postoperative follow-up were obtained. A review of the literature for resections of large vestibular schwannomas was also performed. The authors’ institutional data were compared with the historical data from the literature.RESULTSBetween 2004 and 2017, 45 patients met the inclusion criteria for this retrospective chart review. When compared with findings in a historical cohort in the literature, the authors’ minimally invasive, keyhole retrosigmoid technique for the resection of large vestibular schwannomas achieved higher rates of gross-total or near-total resection (100% vs 83%). Moreover, these results compare favorably with the literature in facial nerve preservation (House-Brackmann I–II) at follow-up after gross-total resections (81% vs 47%, p < 0.001) and near-total resections (88% vs 75%, p = 0.028). There were no approach-related complications in this series.CONCLUSIONSIt is the experience of the senior author that complete or near-complete resection of large vestibular schwannomas can be successfully achieved via a keyhole approach. In this series of 45 large vestibular schwannomas, a greater extent of resection was achieved while demonstrating high rates of facial nerve preservation and low approach-related and postoperative complications compared with the literature.
Background The Coronavirus Disease 2019 (COVID-19) pandemic has had a dramatic impact on individual and societal behaviors, as well as on health care systems. It confers a unique opportunity to examine the relationship among disease, policies, and patterns of activity, as well as their impacts on surgical unit functionality. This study aims to compare the distribution and patterns of injury at a tertiary hand surgery trauma center before and during the COVID-19 pandemic. Methods A retrospective analysis of all patients presenting to the Royal North Shore Hospital hand surgery service in the 5-week period from March 16 to April 21 in 2019 and 2020 was undertaken, forming 2 cohorts for comparison. Demographic, injury, and operative data were collected and compared descriptively using comparative statistics. Results There were 114 primary operative presentations during the 5-week period in 2020, representing a 27.4% decrease from the 157 presentations during the equivalent period in 2019. There was an increase in the proportion of emergency presentations from 73.9% in 2019 to 85.1% in 2020 ( P = .03), with a corresponding decrease in elective presentations during 2020. The incidence of sporting injuries and motor vehicle accidents decreased in 2020, whereas falls and accidents involving knives and tools remained relatively constant. Operating times decreased in 2020, whereas the length of hospital stay remained constant. Conclusions The COVID-19 pandemic and consequent restrictions of activity have had substantial impacts on the patterns of hand trauma and its management. These insights have implications for staff and resource management during times of social disruption in the future.
Intra-articular fracture dislocations of the base of the middle phalanx are complex and debilitating injuries that present a management conundrum when nonreconstructable. Hemi-hamate arthroplasty (HHA) is a treatment modality of particular use in the setting of highly comminuted fractures. This systematic review aims to summarize the reported outcomes of HHA in this context. A literature search was conducted using MEDLINE, Embase, and PubMed, yielding 22 studies with 235 patients for inclusion. The weighted mean postoperative range of movement at the proximal interphalangeal joint was 74.3° (range, 62.0°-96.0°) and at the distal interphalangeal joint was 57.0° (range, 14.0°-80.4°). The weighted mean postoperative pain Visual Analog Scale was 1.0 (range, 0.0-2.0). The weighted mean postoperative grip strength was 87.1% (range, 74.5%-95.0%) of the strength on the contralateral side. Posttraumatic arthritis was reported in 18% of cases, graft collapse in 4.2%, and donor site morbidity in 3.0%, with a mean follow-up period of 28.4 months (range, 1-87 months). Hemi-hamate arthroplasty is a reliable and effective technique for the reconstruction of intra-articular base of middle phalangeal fracture dislocations, affording symptomatic relief and functional restoration. Further research is required to assess the true incidence of long-term complications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
