This fully revised and updated second edition of Transnasal Endoscopic Skull Base and Brain Surgery: Surgical Anatomy and its Applications builds on the acclaimed first edition, focusing on the correlation between endoscopic skull base anatomy and state-of-the-art clinical applications. Among these are the transplanum/transtuberculum, transcribrifom, transclival, and craniocervical junction surgical approaches.

Renowned skull base surgeon Aldo Stamm and leading worldwide experts have compiled a comprehensive multidisciplinary textbook with 72 chapters in 14 sections, didactically organized by regions and diseases. Detailed descriptions of sinonasal, orbital, cranial base, and intracranial anatomy, imaging modalities, and in-depth surgical navigation techniques form the foundation of this remarkable book. The content reflects significant knowledge and diverse perspectives from masters in neurosurgery, otorhinolaryngology, head and neck surgery, neuroendocrinology, intensive care, neuro-anesthesiology, and other disciplines.

Key Highlights

Chapter summaries and highlights facilitate understanding and retention of complex concepts 1,500 beautiful anatomical, operative, and dissection illustrations and photographs enhance understanding of impacted areas 18 accompanying videos provide guidance on endoscopic transnasal approaches in patients with diverse skull base diseases Pearls, pitfalls, and nuances throughout this book provide invaluable insights on achieving optimal outcomes Neurosurgeons, otolaryngologists–head and neck surgeons, and others will greatly benefit from the step-by-step endoscopic procedural guidance and tips in this quintessential skull base surgical reference.

Rechargeable deep brain stimulation implantable pulse generator

Rechargeable deep brain stimulation implantable pulse generator

The Activa PC implantable pulse generator (IPG) demonstrates a significantly reduced batterylife of 2.1 years, with a median battery life of 4.5 years in comparison to 6.6 years in the KinetraIPG. Future technology developments should therefore be focused on improving the battery life of the newer IPG systems 1).

Nonrechargeable deep brain stimulation implantable pulse generators (IPGs) for movement disorders require surgical replacement every few years due to battery depletion. Rechargeable IPGs reduce frequency of replacement surgeries and inherent risks of complications but require frequent recharging 2).

Rechargeable deep brain stimulation implantable pulse generator for movement disorders are well received by patients as initial therapy and after conversion. Mild reduction in stimulation parameters might be allowed after conversion to RC IPG 3).

However, there is now a choice between fixed-life and rechargeable batteries, with each having their own advantages and disadvantages.

Most patients in a adult cohort with movement disorders chose the fixed-life battery. The better lifestyle associated with a fixed-life battery is a major factor influencing their choice. Rechargeable batteries may be more acceptable if the recharging process is improved, more convenient, and discreet 4).


Mitchell et al., evaluated patient experience with rechargeable IPGs and define predictive characteristics for higher satisfaction.

They contacted all patients implanted with rechargeable IPGs at a single center in a survey-based study. They analyzed patient satisfaction with respect to agediagnosis, target, charging duration, and body mass index. They tabulated hardware-related adverse events.

Dystonia patients had significantly higher satisfaction than Parkinson’s disease patients in recharging, display, programmer, and training domains. Common positive responses were “fewer surgeries” and “small size.” Common negative responses were “difficulty finding the right position to recharge” and “need to recharge every day.” Hardware-related adverse events occurred in 21 of 59 participants.

Patient experience with rechargeable IPGs was largely positive; however, frustrations with recharging and adverse events were common. Dystonia diagnosis was most predictive of high satisfaction across multiple categories, potentially related to expected long disease duration with need for numerous IPG replacements 5).


Hitti et al., implanted rechargeable stimulators in 206 patients undergoing DBS surgery, and demonstrated the cost-effectiveness and high patient satisfaction associated with this procedure 6).

Traumatic brain injury (TBI), also referred to as intracranial injury, occurs due to trauma to the brain. It can cause a range of physical, cognitive, behavioral, social and emotional symptoms. Its outcome can vary from complete recovery to permanent disability or death. TBI can occur due to an accident, physical violence or a fall. Its diagnosis involves the use of techniques like magnetic resonance imaging (MRI) and computed tomography. Depending on the extent of the injury, confirmed through a diagnosis, treatment can be minimal or extensive involving medications, surgery and rehabilitation therapies. This book discusses the fundamental as well as modern approaches in the assessment and management of traumatic brain injury. The topics included in this book are of utmost significance and bound to provide incredible insights to readers. It will prove to be immensely beneficial to students and researchers in this domain.
