Brain imaging and neurophysiological methods have been rapidly developed. The purpose of this book is to describe hearing problems which are caused by various kinds of brain diseases in central auditory pathway. Each topic is explained to use a lot of figures such as brain imaging and neurophysiological data comparing with neuropsychological tests. Readers will understand what happens in patients, when bilateral auditory nerve and auditory cortex are damaged in patients. Some patients can hear but cannot discriminate meanings of speech, music and environmental sounds. The author tries to explain why such a difference occurs.

This atlas gives careful step-by-step guidance for endoscopic sinus surgery. In doing so, it provides exciting firsthand accounts of modern advanced endoscopic sinus procedures. In the first part of the book the surgical anatomy of the nose and sinuses and the basic surgical techniques are described. The second part deals with advanced techniques and postoperative care. The detailed, step by step narratives - integrated with many intraoperative photographs - accurately convey both surgical fundamentals and nuances. For each procedure the authors give a piece of advice ("golden rules"), making it ideal for those who want to implement well-coordinated surgical approaches to sinus disease.

Hearing Impairment - An Invisible Disability is the first work of its kind to comprehensively cover all aspects of hearing impairment. It covers the following categories through more than 100 contributions from all over the world to constitute an encyclopedia of hearing impairment:

- Hearing Basics: What does hearing impairment mean? Its causes and effects are explained through many real-world examples.

- Children: Childhood is a time when hearing impairment often begins, so proper treatment at an early stage can help alleviate difficulties and allow for as normal a life as possible. Many case studies from both the developed and developing parts of the world, including Indonesia and Latin America in the latter category, are provided to aid comprehension.

- Hearing Aids: Through newly emerging technology and with the help of electronics companies, new and affordable hearing aids are being developed and marketed. The authors take a closer look at this burgeoning field.

- Medical Aspects: Medical treatment of hearing impairment has recently shown remarkable change, manifested in improved techniques and applications all over the world. Although mainly of relevance to researchers and practicing physicians, the clear explanation of the medical and technical terminology is likely to be of interest to all concerned with the future of hearing impairment.

- Social and International Help: With a wealth of assistance from individuals, NGOs, and international organizations specifically tailored to help the hearing impaired, those in need of guidance can gain confidence from the knowledge that substantial support is available to help them pursue a full and varied life.

Affirmative legislative action in many countries now requires that public spaces and services be made accessible to disabled people. Although this is often interpreted as access for people with mobility impairments, such legislation also covers those who are hearing or vision impaired. In these cases, it is often the provision of advanced technological devices and aids which enables people with sensory impairments to enjoy the theatre, cinema or a public meeting to the full. Assistive Technology for the Hearin-impaired, Deaf and Deafblind shows the student of rehabilitation technology how this growing technical provision can be used to support those with varying reductions in auditory ability and the deafblind in modern society. Features: instruction in the physiology of the ear together with methods of measurement of hearing levels and loss; the principles of electrical engineering used in assistive technology for the hearing impaired; description and demonstration of electrical engineering used in hearing aids and other communications enhancement technologies; explanation of many devices designed for every-day living in terms of generic electrical engineering; sections of practical projects and investigations which will give the reader ideas for student work and for self teaching. The contributors are internationally recognised experts from the fields of audiology, electrical engineering, signal processing, telephony and assistive technology. Their combined expertise makes Assistive Technology for the Hearing-impaired, Deaf and Deafblind an excellent text for advanced students in assistive and rehabilitation technology and to professional engineers and medics working in assistive technology who wish to maintain an up-to-date knowledge of current engineering advances.

Secondary Rhinoplasty begins with the basic anatomy of the nose that often predetermines which technique is possible and which is realistic. Each region of the nose and its particular anatomy is analyzed and explained as a specific unit and as part of the total aspect of management. Reconstruction of the nose, biologic deteriorations, tumors, the effects of aging, and associated congenital abnormalities are also dealt with. Nothing of substance has been left out, and yet the primary value of this text is the presentation of the most optimal surgical methods of correction.

Guidelines, operative techniques, and postoperative management for rhinoplasty of the non-Caucasian nose. Starting with the basics of Black, Hispanic, and Asian nasal anatomy, the book goes on to encompass preoperative nasal evaluation and surgical planning. The author demonstrates his renowned techniques, including those for nasal septum and turbinates, nasal dorsum and bridge, alar rim and nasal base reduction, and the nasal tip. Close to 200 clinical and operative illustrations - 50 in full colour - are backed by important protocols for revision rhinoplasty as well as for the management of risks and complications. A must for all plastic surgeons wishing to add the latest in non-Caucasian nasal refinement techniques to their office practice.

For the beginner or for the accomplished sinus surgeon, mastering the anatomy of the lateral nasal wall is an ongoing challenge. Even though there are excellent standard anatomical references and equally outstanding sinus courses with cadaver dissection, a reference depicting the surgical anatomy is needed. A step-by-step surgical approach on the anterior nasal spine to the anterior wall of the sphenoid is presented. The sinus surgeon is confronted with a wide range of different spaces created by the ethmoid bone. No other bone in the human body has so many anatomical variations. Four critical anatomical structures are emphasized as the foundation for a precise approach to surgery of the maxillary, anterior ethmoid, frontal, and posterior ethmoid sinuses. The goal of this book is to meet the tremendous challenge of offering an anatomical approach which will serve the sinus surgeon of every level of experience and expertise.

The present book arose from a conference on Speech Motor Dynamics in Stuttering held at the University of Nijmegen in Nijmegen, the Netherlands from June 13-15, 1985. The conference was organized on the occasion of the 25th anniversary of the Department of Speech Pathology of the University Hospital. The topic selected for the conference and now developed within this book, Speech Motor Dynamics in Stuttering, was judged to be particularly timely and especially relevant to an emerging body of work on stuttering. For over ten years there had been no confer ences that brought together researchers who have worked on stuttering from perspectives stressing the dynamics of motor processes. Yet during that time major changes have occurred in research on stuttering which signify a growing level of scientific maturity within the problem area. This book attempts to character ize a number of major trends in research on speech motor processes in stuttering. There has been a lessening in the postulation of causes of stuttering in the form of global hypothesis which have tenuous ties to empi rical data. New ideas about speech motor processes in stuttering have been stimulated by researchers who have done productive work on more general issues of motor control. This book therefore directs our attention to a number of models of speech production which are relevant to stuttering."

In this first volume of the series Update in Plastic Surgery, internationally acknowledged experts give an up-to-date view of the clinical possibilities in plastic surgery which result from video-assisted microsurgery with the endoscope. Advantages and disadvantages are discussed, and reasons are presented why it can be assumed that this technique will be the standard in plastic surgery within a few years.

Historically, disorders of salivary glands tend to be 'underdiagnosed and overtreated'. In the vast body of literature on this subject, emphasis has usually been put on therapeutic modalities of various diseases of the salivary glands. Whereas therapy and pathology have been treated in numerous thorough studies, the (patho )physiology of the salivary glands has remained rather poorly understood. Even less attention has been given to the diagnostic methods. Until a few decades ago, diagnosis consisted mainly of a clinical examin ation which included the patient's history, inspection, and palpation. These methods remain crucial, but a variety of new diagnostic tools have appeared since then. Their clinical value is still subject to controversy; each method has its advocates and opponents. The indications for enrolling a patient at a given point in a series of diagnostic procedures are interpreted differently. One of the most striking examples is the use of sialography. This has become a classic diagnostic procedure. Although sialography is still a useful method, it has considerable disadvantages, limitations, and even contraindications. In the major teaching hospitals, residents still tend to consider sialography as a panacea for the majority of their diagnostic problems, whereas the infor mation provided is actually rather restricted. Other modern methods such as CT and MRI have taken over the role of sialography to a certain extent. This also applies to ultrasonography and scintigraphy. Moreover, microbiol ogy, sialometry, sialochemistry, cytology, and histopathology may give super ior information in certain cases."

This manual is conceived as an aid to AO course participants both in grasping theoretical principles and in performing practical exercises, as well as a practical guide for clinicians in the application of AO principles. These principles are discussed in Part I and related to notions of stability, biomechanics, and technique. In addition to interfragmentary fixation and load bearing, the technique of external fixation is explained. The use of rigid external fixators with the mandible is proposed as a replacement for pin fixation, which has been obsolete for over two decades. Part II is a practical guide to the theoretical principles set forth in the first section of the volume, with the focus on case studies classified according to fracture type. This section provides a solid empirical basis of particular value in establishing indications and selecting appropriate techniques. Equally important is the anatomy of surgical points of access. In Part III, the increasing variety of indications for rigid internal fixation is confirmed. Three areas take on particular relevance here: the surgical treatment of pseudarthrosis, the by-pass of primary defects as an integral part of mandibular tumor surgery, and sagittal splinting and condylar replacement for orthopedic interventions involving the locomotor system of the mandible. A foldout entitled "AO Classification of Mandibular Fractures" is inserted at the back of the book. Its purpose is to help the clinician confronted by an acute case to determine its classification.

Microdialysis is a minimally invasive method which enables continuous monitoring of parameters in the extracellular space of various tissues. It has been investigated in animal models for over a decade, and many publications have provided insight into its advantages and disadvantages. However, in spite of its enormous potential for revealing metabolic processes in normal and pathological tissue, microdialysis in humans is still in its infancy. Clinical neurointensive medicine nowadays demands much more than conventional monitoring methods. As already shown by jugular bulb measurements of oxygen and lactate, in the future clinicians will want to have access to continuous neurochemical information from the patient. This information could be used to prevent those enigmatic secondary lesions which play such a negative role in neurointensive medicine, or at least enable treatment of them at an early stage. The extensive information now available from the laboratory would help with the interpretation of clinical analogues. In the University Clinic of Neurosurgery in Basel we have been involved in the field of micro dialytic monitoring for several years and have recognised the problems, both technical and ethical, which are involved in taking the difficult step from animal experiments to clinical application. In 1994 we thought that research on clinical microdialysis had reached the stage which would enable scientists and clinicians to have many fruitful discussions.

Doctors Pellet, Cannoni and Pech have joined forces to write a masterly work on the subject of otoneurosurgery and tumors of the base of the skull. The anatomic illustrations, derived from their meticulous dissections, are of excellent quality and a credit to the famed tradition of French neuroanatomists of the past. It is evident that the operative techniques described by these surgeons indicate that they have spent a great deal of time in the dissecting-room and that they have completely mastered the temporal bone. A perfect knowledge of the fundamental anatomy of the petrous bone is essential before embarking on the difficult surgical procedures in this region of the brain and base of the skull. Reading this work makes it abundantly clear that the results of this type of sur gery are vastly improved when neurosurgeons and otologists combine their skills. Each of these specialists brings his unique experience and entire knowledge to the operation for the greater benefit of the patient. We wish to congratulate Doctors Pellet, Cannoni and Pech on the publication of this excellent work. March 1990 William F. House, MD William E.

Practical and case-based, Neuro-Ophthalmology and Neuro-Otology is an invaluable resource for practitioners, trainees, and residents in various fields.

Although pitch has been considered an important area of auditory research since the birth of modern acoustics in the 19th century, some of the most significant developments in our understanding of this phenomenon have occurred comparatively recently. In auditory physiology, researchers are now identifying cells in the brainstem and cortex that may be involved in the derivation of pitch. In auditory psychophysics, dramatic developments over the last few years have changed our understanding of temporal pitch mechanisms, and of the roles of resolved and unresolved harmonics. Computational modeling has provided new insights into the biological algorithms that may underlie pitch perception. Modern brain imaging techniques have suggested possible cortical locations for pitch mechanisms.

This timely volume brings together the more recent findings, while emphasizing their relation to the discoveries of the past. It brings together insights from several different methodological areas: physiology, psychophysics, comparative, imaging, etc., in addressing a single scientific problem. Pitch perception can be regarded as one of the main problems of hearing, and the multidisciplinary approach of the book provides a valuable reference source for graduate students and academics.

Sensory Neuroscience: Four Laws of Psychophysics organizes part of psychophysics -- a science of quantitative relationships between human sensations and the stimuli that evoke them. Although psychophysics belongs to sensory neuroscience, and is coupled to neurophysiology, it has also branched out to various specialized disciplines, including the disciplines of vision and hearing, ophthalmology, optometry, otology, and audiology. Due to this diversification and fragmentation, psychophysics has had an ad-hoc, phenomenological orientation. Besides Weber's law of differential sensitivity, and the still-controversial Stevens' power law, it has lacked a systematic grid of scientific laws. Sensory Neuroscience: Four Laws of Psychophysics provides valid unifying principles and systematic applications for this otherwise fragmented precursor of experimental psychology, and defines four multisensory relationships of substantial generality between sensations and the underlying stimulus variables. This book will be particularly useful to auditory researchers, experimental psychologists, and behavioral neuroscientists.

The vestibular labyrinth consists of ? ve compartments: the lateral, anterior, and posterior semicircular canals, the utricule, and the saccule. At the beginning of the twentieth century, Robert Barany proposed the caloric test as a clinical test of the lateral semicircular canal. This test enabled clinicians to assess the individual lateral semicircular canal function easily by using the simple method of irrigating the external ear canal with cold or warm water and observing the induced nyst- mus. We believe that the caloric test was a breakthrough in the ? eld of vestibular research. However, as far as the other compartments were concerned, there was no simple clinical test equal to the caloric test for the lateral semicircular canal function. At the end of the twentieth century, the vestibular evoked myogenic potential (VEMP) test was proposed as a new method for assessing the individual saccule function. This test has some unique attributes. First, it uses sound stimulation, even though it is a test of the vestibular system. This appears to be a contradiction n- rophysiologically. As a result, in its early stages there were controversies conce- ing the origin of the responses. However, such controversies have been overcome by basic neurophysiological studies and clinical studies. Above all, sound sensit- ity of the saccular afferents shown in cats and guinea pigs with single-unit recording methods became the main supporting evidence. Nowadays, VEMP is one of the routine clinical tests for balance disorder."
