  • Patient Information – Ear Surgery Instructions
    The Oregon Clinic, Plaza ENT Division 5050 NE Hoyt #655, Portland, OR 97213 Phone: 5034882400 Fax: 5032310121 Patient Information – Ear Surgery Instructions Pre- and Post-operative Instructions for Ear Surgery (not including ear tubes) Before Surgery: Many ear surgeries involve manipulation of the eardrum (tympanic membrane), and some require the removal of bone to facilitate the treatment of your ear disease. As with any operation, infection, scarring, and blood clot formation (hematoma) are possible. The facial nerve is at risk for injury or temporary weakness during any ear surgery. Dizziness following surgery may be expected. Hearing loss or ringing in the ear (tinnitus) may be more pronounced. Taste disturbance is not uncommon in certain ear surgeries for a few weeks following surgery and, in a few instances, could be prolonged or permanent. An incision may be made behind your ear, on your earlobe, or behind the pointed cartilage in front of your ear (the tragus). These areas normally heal without problems or obvious scars. Hair around the ear may or may not be shaved. Flying is usually permitted one month after surgery. Swimming may be allowed six weeks after surgery, but check with your doctor first before resuming swimming or other water sports. If your work is not strenuous and depending upon the type of surgery you’ve had, you may return to work 3 to 4 days from the date of surgery. Generally, you will be seen about 2-3 weeks after surgery. This gives your eardrum time to heal before we see you back. Pre-operative Instructions: 1.

  • Basic Anatomy and Physiology of the Ear 11
    1 BASIC ANATOMY AND PHYSIOLOGY OF THE EAR J. Irwin Introduction The ear is a small, complex series of interlinked structures that are involved in both maintenance of normal balance and the sense of hearing. In order to hear, the ear collects the sound waves that arrive as pressure changes in air and converts these into neurochemical impulses that travel along the cochlear- vestibular nerve to the brain. There are both active and passive mechanisms involved in this process.The prime function of the vestibular system is to detect and compensate for movement. This includes the ability to maintain optic fix- ation despite movement and to initiate muscle reflexes to maintain balance. For the purposes of describing structure and function the ear is usually split into four distinct parts. These are the outer ear, the middle ear and the audi- tory and vestibular parts of the inner ear (Figure 1.1). The outer ear This is sometimes known as the external ear and consists of the ear that is visible on the side of the head (the pinna), the external auditory meatus (ear hole) and the ear canal (external auditory canal) that leads to the eardrum (or tympanic membrane). The tympanic membrane has three layers and the outer layer is usually included as part of the outer ear. THE PINNA This is, for the most part, a piece of cartilage covered by skin (Figure 1.2). There is also a fatty earlobe in most people. The skin covering the cartilage is Infection and Hearing Impairment. Edited by V.E. Newton and P.J.

  • Intraoperative Neuromonitoring Techniques in the Surgical Management of Acoustic Neuromas
    Neurosurg Focus 33 (3):E6, 2012 Intraoperative neuromonitoring techniques in the surgical management of acoustic neuromas TAEMIN OH, B.A.,1 DANIEL T. NAGASAWA, M.D.,1 BRENDAN M. FONG, B.S.,1 ANDY TRANG, B.S.,1 QUINtoN GOPEN, M.D.,3 ANDREW T. PARSA, M.D., PH.D.,2 AND ISAAC YANG, M.D.1,4 Departments of 1Neurosurgery and 3Otolaryngology ENT, David Geffen School of Medicine, University of California, Los Angeles; 4UCLA Jonsson Comprehensive Cancer Center, University of California, Los Angeles; and 2Department of Neurosurgery, UCSF School of Medicine, University of California, San Francisco, California Unfavorable outcomes such as facial paralysis and deafness were once unfortunate probable complications following resection of acoustic neuromas. However, the implementation of intraoperative neuromonitoring during acoustic neuroma surgery has demonstrated placing more emphasis on quality of life and preserving neurological function. A modern review demonstrates a great degree of recent success in this regard. In facial nerve monitoring, the use of modern electromyography along with improvements in microneurosurgery has significantly improved preservation. Recent studies have evaluated the use of video monitoring as an adjunctive tool to further improve outcomes for patients undergoing surgery. Vestibulocochlear nerve monitoring has also been extensively studied, with the most popular techniques including brainstem auditory evoked potential monitoring, electrocochleography, and direct compound nerve action potential monitoring. Among them, direct recording remains the most promising and preferred monitoring method for functional acoustic preservation. However, when compared with postoperative facial nerve function, the hearing preservation is only maintained at a lower rate. Here, the authors analyze the major intraoperative neuromonitoring techniques available for acoustic neuroma resection.

  • Fat Graft Myringoplasty
    64 Pomeroy St., Suite B, Cortland, NY 13045 607-662-4521 tel 607-662-4523 fax Surgeon – Dr. Manoj Kumar Date of Procedure: Fat Graft Myringoplasty Definition Myringo = tympanic membrane Plasty = a surgical procedure for the repair, restoration, or replacement (as by a prosthesis) of a part of the body This procedure involves repairing a small hole in the eardrum with a small piece of fat taken from the earlobe. Purpose of Procedure The purpose of this procedure is to restore a normally functioning eardrum. Holes in the eardrum may be due to infections that have drained through the eardrum, a traumatic injury, or a persistent opening following ear tube removal. Preparation As with any procedure in which anesthesia is administered, you will be asked not to eat or drink anything after midnight on the evening prior to your surgery. You may brush your teeth in the morning but not swallow the water. If you are on medications that must be taken, you will have discussed this with us and/or the anesthesiologist and instructions will have been given to you. The procedure will not be performed if you are currently taking, or have recently taken any medication that may interfere with your ability to clot your blood (“blood thinners, aspirin, anti-inflammatory medicines, etc...”). We will have reviewed all of your current medications with you during the pre-operative / pre-procedure consultation. You are obligated to inform us if anything has changed (medication or otherwise) since your previous visit. Procedure The operation involves taking a small piece of fat from the earlobe through a small incision.

  • Nervous System - Sensory Input
    Nervous system - sensory input. Overview: Sensory neurons are designed to register certain chemical, physical, electrical or other stimulus. If this stimulus is strong enough, this sets off an action potential. This impulse is then transmitted to the appropriate part of the nervous system. Incidentally, the perception of “light”, “sound”, etc. is not determined by the “receptor”, but rather on how/where the signal winds up (mostly in the brain). As a silly example: suppose we could unplug nerves coming into the brain from the eyes. Instead, we plug in nerves coming from the ears. Now sound would be registered as “light”, but who knows what this would be interpreted as. There are 5 main categories of sensory receptors (actually, lots more, but these will do for now): Mechanoreceptors - mechanical changes (pressure, touch, etc.). Pain receptors - sense pain. Thermoreceptors - temperature receptors. Chemoreceptors - taste, smell, other chemical receptors. Electromagnetic receptors - light, other electromagnetic waves. [Notice that this list really has nothing to do with the proverbial “5 senses”]. Mechano, pain & thermo receptors. In the skin - a lot of these come together in the skin and form our sense of “touch” [Fig. 29.3A, p. 590]. Touch is actually made up of several different receptors. Pain - this is very important and causes a strong negative reaction. This helps us avoid damage. Leprosy is a disease which (among other things) can shut down pain receptors. Mechanoreceptors in the skin: Deep touch (pressure) - for example, what you feel when sitting down. Light touch (often assisted by hairs) - used to determine texture, air currents, etc. Thermorecptors: Separate receptors for hot and cold (separate) exists.
