This book incorporates a wide range of cases. With around 1000 images this atlas takes readers through case studies covering the clinical presentation, radiological findings, surgical techniques, and outcome. The pertinent anatomical information required to execute these orbital procedures via the trans-nasal route successfully is covered in a separate section. Schematic diagrams are presented to explain surgical procedures. This book is helpful to otorhinolaryngologists, ophthalmic and oculoplastic surgeons, and neurosurgeons who encounter such cases and need to perform orbital surgeries alone or in conjunction with the team, depending on the extent of the disease.
