Revisiting Surgery in the Current Era of Gamma Knife for Cavernous Sinus Lesions.

Background: The challenges associated with surgeries of cavernous sinus (CS) lesions have shifted the management trend towards upfront gamma knife radiosurgery (GKRS). Although GKRS is effective in arresting the progression of certain small residual/recurrent lesions, its efficacy in alleviating neurological deficits is less evident. Furthermore, GKRS without establishing the histopathological diagnosis, at times can be detrimental. Objective: We present our clinical experience to reemphasize the role of surgery for CS lesions in the current era of upfront GKRS. Materials and Methods: We reviewed our database of 32 patients with various CS lesions treated by surgery for progressive cranial nerve deficits. The follow-up data were analyzed for the extent of resection, and in particular for improvement in their symptoms. Results: The lesions were confirmed as hemangioma (CSH)-8, meningioma-8, trigeminal schwannoma-6, chordoma-3, residual pituitary with CS extension-3, fungal granuloma-3, and dysgerminoma-1. Symptoms improved in 23 (complete in 13) and remained at least static in six patients. Follow-up ranged from 4-36 months. Conclusions: The nature of pathology should determine the management modality in CS lesions. Excision of CS schwannomas and chordomas yields rapid clinical improvement and good long-term outcomes. Resection is preferred for large CSH and functioning pituitary tumors. Although the clinical improvement may be less dramatic, surgery debulks the meningiomas. Most importantly, surgery also establishes the histopathological diagnosis of CS lesions. Even with an easy alternative of upfront GKRS, resection has a definite role in the primary management of most CS pathologies.

Head injury care in a low- and middle-income country tertiary trauma center: epidemiology, systemic lacunae, and possible leads.

BACKGROUND: Although head injury (HI) from low- and middle-income countries (LMIC) heavily contributes to the global disease burden, studies are disproportionately less from this part of the world. Knowing the different epidemiological characteristics from high-income nations can target appropriate prevention strategies. This study aims to provide a comprehensive overview of the clinico-epidemiological data of HI patients, focusing on the existing challenges with possible solutions from a developing nation's perspective. METHODS: This is a prospective, registry-based, observational study of HI in an Indian tertiary trauma-care center over 4 years. Various clinico-epidemiological parameters, risk factors, and imaging spectrum were analyzed in a multivariate model to identify the challenges faced by LMIC and discuss pragmatic solutions. RESULTS: The study included a large-volume cohort of 14,888 patients. Notably, half of these patients belonged to mild HI, despite most were referred (90.3%) cases. Only one-third (30.8%) had severe HI. Less than a third reached us within 6 h of injury. Road traffic accidents (RTA) accounted for most injuries (61.1%), especially in the young (70.9%). Higher age, males, RTA, helmet non-usage, drunken driving, systemic injuries, and specific imaging features had an independent association with injury severity. CONCLUSIONS: The study represents the much-needed, large-volume, epidemiological profile of HI from an LMIC, highlighting the suboptimal utilization of peripheral healthcare systems. Strengthening and integrating these facilities with the tertiary centers in a hub and enhanced spoke model, task sharing design, and efficient back-referrals promise effective neurotrauma care while avoiding overburden in the tertiary centers. Better implementation of road safety laws also has the potential to reduce the burden of HI.
