Bleeding is a major factor that hinders visualization in head and neck surgery and is a risk factor for intraoperative complications and perioperative morbidity. Endoscopic approaches also pose significant technical challenges to managing expected intraoperative bleeding and vascular injury. The approach for this publication in Otolaryngologic Clinics is to provide clinically relevant information in a problem-based manner that encompasses assessment to identify patients with a high risk for vascular complications, pre-operative, intra-operative and post-operative strategies to manage expected bleeding and major vessel injury during endoscopic sinus and skull base surgery for inflammatory and neoplastic diseases. Clinically relevant anatomy, physiology, pharmacology, and surgical and interventional radiology techniques to manage bleeding are outlined and an algorithm for management of major vessel injury such as internal carotid artery injury is presented. Because skull base surgery is generally undertaken as a team approach, this information is relevant to the subspecialized ENT surgeon from rhinology or head and neck specializations, to neurosurgeons, to interventional radiologists, and to neurophysiologists who monitors intraoperative cerebral and cranial nerve activity for these operations. Carl Snyderman leads this issue with Harshita Pant and has composed topics and assembled an expert group of practitioners to provide information. The reader will find this a novel, focused, and indispensable resource on all issues of hemostatis in head and neck surgery.

Ear, Nose and Throat for Medical Students: A Case Based Approach is a novel guide aimed at improving your knowledge of common otolaryngology disorders as well as your clinical and diagnostic skills. The content provides a valuable aide for medical students preparing for written finals and OSCE based examinations. The book will also be of interest to GPs wishing to revise their ENT knowledge, and junior doctors starting their first ENT job. The book is helpfully divided into succinct sections, each addressing common pathology pertaining to the ear, nose, throat, head, neck and also paediatric otolaryngology. This book thereby covers a large range of topics you may encounter in exams and clinical practice, and does so in a concise, attractive and accessible manner. Numerous fictional cases have been designed specifically to guide you through the clinical reasoning process from start to finish. Also included is a range of questions to supplement and expand your knowledge of important diseases or presentations. Each case begins with a 'Focusing question' - often regarding diagnosis or aetiology. This is followed by a series of 'Management' questions to test your clinical reasoning, history taking and examination skills. The questions also provide an opportunity to acknowledge the use and importance of investigations and devising treatment plans. Finally, a challenging 'Additional questions' section has been added on to several cases to complete the learning by asking potential viva questions regarding relevant basic science and pathophysiology. The simple-to-read layout and abundance of clinical pictures ensures easy recall of information during outpatient practice and examinations.

Ear, Nose and Throat surgery is a specialty that is often inadequately covered in Medical Schools worldwide and very few junior doctors encounter it during foundation training or internship. As a result, there is always a sense of anxiety and a feeling of entering the unknown when junior doctors, such as core surgical trainees, GP trainees, Foundation and Emergency doctors see patients with ENT conditions requiring urgent care. Currently, there is no concise guide book to address this fundamental issue without subjecting the reader to hours and hours of trawling through lengthy didactic text. With this in mind, and utilising the principles of Pointillism, the authors have put together an excellent succinct guide. The book is divided into five chapters, each consisting of urgent care conditions pertaining to (1) Ear, (2) Nose and Bronchus, (3) Throat and Oesophagus, (4) Neck and Head or (5) Complications of Treatment. All the essential information is clearly provided in 5 logical management steps: history, examination investigation(s), treatment and follow-up. Additional relevant points, tables and figures are provided to further enhance your understanding and retention of the subject matter. Like the previous two books from ENT TZAR team, this guide is lavishly illustrated with clinical photographs to optimise learning and confidence to deal with the challenges of managing urgent care conditions in Otolaryngology.

Vertigo, dizziness, and imbalance rank amongst the most common presenting symptoms in neurology, ENT, geriatric medicine, and general practice. These symptoms can originate from many different organs and systems, such as the inner ear, general medical conditions, neurological and psychological disorders. The Oxford Textbook of Vertigo and Imbalance provides an up-to-date summary of the scientific basis, clinical diagnosis, and management of disorders leading to dizziness and poor balance. This textbook is conceptually divided into three sections, detailing the scientific basis, general clinical issues, and specific diseases diagnosed in clinical practice that are responsible for complaints of dizziness and imbalance. Individual chapters address benign paroxysmal positional vertigo, vestibular migraine, vestibular neuritis, stroke, and Meniere's disease. Additional chapters follow a syndrome-based approach and cover multiple conditions, including cerebellar disorders, bilateral vestibular failure and gait, and psychological disorders. The print edition is complemented by an online version, which allows access to the full content of the textbook, contains links from the references to primary research journal articles, allows full text searches, and provides access to figures and tables that can be downloaded to PowerPoint. It serves a useful clinical reference for neurologists, otorhinolaryngologists, audio-vestibular physicians, and senior trainees in those specialties.
