The FRCS Oral and Maxillofacial Surgery (OMFS) exam is split into three parts: written, viva and mock clinical consultations with an examiner and an actor in the role of a patient. These consultations fall into two formats: 'short case', where the examiner poses questions specific to the patient's case, and 'long case' where the candidate must diagnose the patient's presenting problem and suggest an appropriate course of treatment. FRCS (Oral & Maxillofacial Surgery) Part 2: 100 Clinical Cases focuses on the clinical component of the exam and is structured according the FRCS OMFS syllabus. Each chapter starts with cases devoted to examination of the patient, history taking and investigations. Subsequent cases feature 'short case' clinical scenarios commonly encountered in the exam. Where relevant to exam practice, a 'long case' is included at the end of each chapter. The 'short cases' feature mock questions, while the 'long cases' also include an examiner's mark sheet listing the answers and actions candidates must perform to achieve full marks.
