Repair of ptosis cases with good levator function yields excellent results. A good outcome can be also obtained in cases with poor levator function, however, in such cases; a large degree of levator advancement may be required, which may result in postoperative dry eyes, unnatural eyelid curvature and astigmatism. These cases are therefore better treated with sling surgery. With the right patient selection, the levator resection technique is an effective method for ptosis repair. Keywords: Transcutaneous blepharoptosis surgery, levator aponeurosis, Müller’s muscle, levator resection. INTRODUCTION muscle is divided into 2 branches in the periphery: the superior branch which continues to the levator aponeurosis, Blepharoptosis surgery is one of the most popular and the inferior branch from which Müller’s muscle operations in the field of ophthalmic plastic and originates. Although the thickness of each branch is almost reconstructive surgery. The specific surgical method for identical, the superior branch tends to be thicker than the repairing blepharoptosis is selected according to the degree inferior branch.

  • The Five-Minute Neurological Examination
    THE FIVE-MINUTE NEUROLOGICAL EXAMINATION Ralph F. Józefowicz, MD Introduction The neurologic examination is considered by many to be daunting. It may seem tedious, time consuming, overly detailed, idiosyncratic, and even capricious. Every neurologist has his/her own version of the examination, and may appear to use “magical thinking” to come up with a diagnosis at the end. In reality, the examination is quite simple. When performing the neurological examination, it is important to keep the purpose of the examination in mind, namely to localize the lesion. A basic knowledge of neuroanatomy is necessary to interpret the examination. The key to performing an efficient neurological examination is observation. More than half of the neurological examination is performed by simply observing the patient – how he/she speaks, thinks, walks, moves, and simply interacts with the examiner. A skillful observer will already localize a lesion, based on simple observations. Formalized testing merely refines the diagnosis, and may only require several additional steps. Performing an overly detailed neurological examination without a purpose in mind is a waste of time, and often yields incidental findings that cloud the picture. The following three pages contain an outline of the components of the five-minute neurological examination, followed by a suggested order for performing this examination. I have also included a detailed handout describing the components of a comprehensive neurological examination, as well as the significance of abnormal findings. Numerous tables are included in this handout to aid in neurological diagnosis. Finally, a series of short cases are included, which illustrate how an efficient and focused neurological examination allows one to make an accurate neurological diagnosis.

All neurovascular structures pass through bony openings in ► bony surface contours the sphenoid bone before diversification in the mid and anterior orbit. A set of ► periorbita landmarks such as the optic and maxillary strut comes into new focus. Within the ► extraocular muscles topographical surfaces of the internal orbit the lazy S-shaped floor and the poster- ► connective tissue omedial bulge are principal determinants for the ocular globe position. The inferome- compartments dial orbital strut represents a discernible sagittal buttress. The periorbita and orbital soft ► nerve and vessel tissue contents—extraocular muscles, septae, neurovasculature—are detailed and put supply into context with periorbital dissection.

  • Neuroscience Flash Cards, Second Edition, Is a Logical Follow-Up to Netter’S Atlas of Neuroscience, Second Edition
    Netter’s Neuroscience Flash Cards Second Edition David L. Felten, MD, PhD Acknowledgments Netter’s Neuroscience Flash Cards, second edition, is a logical follow-up to Netter’s Atlas of Neuroscience, second edition. Both publications are intended to provide a visually oriented, succinct roadmap to the basic neurosciences and their application to human disease and its treatment. I have thoroughly enjoyed working with Julie Goolsby (Associate Developmental Editor), Marybeth Thiel (Senior Developmental Editor), and Elyse O’Grady (Editor, Netter Products) from Elsevier in the long and challenging process of producing the Flash Cards and Atlas. Their helpfulness, diligence, professionalism, and commitment to bringing the Netter illustrations to yet more generations of physicians and health care professionals are inspirational. I also gratefully acknowledge the mentorship and wonderful teaching of Institute Professor Walle J.H. Nauta, M.D., Ph.D. from the Massachusetts Institute of Technology; his superb organization of the nervous system, brilliant insights, and use of overviews has inspired generations of neurosciences researchers, educators, and practitioners. I gratefully acknowledge the love, support, and encouragement of my wife, Dr. Mary Maida, who continues to tolerate mountains of books and papers piled all over the house and office while I work on my Netter projects. And finally, I acknowledge the inspiration that my mother, Jane E. Felten, provided through her long challenge with the aftermath of polio. Although she was badly crippled by the disease at the age of 8, she never let this neurological disease interfere with a full and happy life. Her example demonstrates that the strength of human determination, will power, and faith can be powerful motivators for successful living, and that the indomitable human spirit can overcome even the most daunting challenges.
