Preface – Diseases of Ear, Nose and Throat

With this sixth edition, the book completes 22 years of ser- vice to its readers. The speciality of ENT, often called oto-laryngology or otorhinolaryngology has diversified intoseveral subspecialities of otology, otoneurology, rhinology,laryngology, bronchoesophagology, paediatric otolaryngol-ogy, skull base surgery, and now emerging subspeciality ofneuro-rhinology where the brain tumours related to skullbase are being treated by endoscopic nasal approaches. Diseases of Ear, Nose and Throat

Thegrowth in several branches owe their emergence to rapidstrides being made in technology such as imaging tech-niques from simple X-ray to CT, MRI, MR angiography,PET-CT and simultaneous PET-MRI. The development ofendoscopes from 4 mm to nearly 1 mm with various view-ing angles, lasers, computers and miniature cameras whichcan be fixed on the tip of the flexible endoscopes have fur-ther revolutionized surgery. This further has given birth tominimally invasive surgery, navigation surgery and roboticsurgery. With the growth of the speciality both in breadthand depth, it throws several challenges to authors on howmuch to introduce the subject yet to be concise but compre-hensive, and not to lose sight of the basic fundamentals andclinical applications to students entering medical professionin a readable form.In the present edition, all the chapters have been revised,updated and augmented. Some have been completelyrewritten and expanded. New chapters have been addedon thyroid disorders, thyroid surgery and proptosis. Severalnew diagrams, algorithms, tables, flowcharts and clinicalphotographs have been added to make the subject eas-ily understandable. Diseases of Ear, Nose and Throat

The chapter on “Nuggets for RapidReview” provides useful tips which help solve several MCQsoften set in the university or board examinations.Mnemonics set here and there are useful as aide memoireto recall and reproduce the subject for exam going students.The book is clinically oriented with practical approach to thepatient as before and provides broad insight into the subjectfor undergraduates. It is hoped that this edition of the book will also prove useful to students of DLO, MS/MD and DNB(Diplomate National Board) as a foundation course beforethey take recourse to comprehensive volumes of the subject.It will also be useful to general practitioners, students ofnursing, audiology and speech therapy, and to those study-ing alternative systems of medicine such as Ayurveda, Sidha,Unani and Tibbia, Homeopathy and Physiotherapy. Theauthors will feel gratified if the above objectives are fulfilled.There is always scope for improvement in any work and theauthors will welcome any suggestions and comments fromlearned teachers and students at [email protected] or[email protected]
