  • Exploring tinnitus by the assessments of electrocorticography - Seeking possible physiological mechanisms

    China Medical University Hsinchu Hospital
    Taiwan
    Abstract

    Tinnitus is a condition where individuals are conscious of a particular sound without outside stimulation. We assume that there are huge number of people suffer from tinnitus and they are desired to find solutions. Though many kinds of managements, these all have limited success and effective cure remain missing as the underlying pathophysiology is still poorly understood. Although there is currently no perfect way to cure tinnitus, it is important to figure out the physiological mechanisms of tinnitus generation and to develop a good solution to reliably eliminate the phantom sounds inside the patients by both auditory neuroscientists and clinicians. It might help developing new management for tinnitus if we understand the details of pathophysiological mechanisms. In order to explore the changes of auditory pathway on tinnitus, we applied the combination of the behavior assessment and electrocorticography to compare the tinnitus group and nontinnitus group. The results revealed that the tinnitus related increased neural activities and neural synchrony. Results taken together will suggest that the tinnitus perception is generated by the hyperactive and enhanced synchrony. These might be a good point to induce the generation of subject tinnitus. Besides, Further results will be provided for more insights on tinnitus perception. It is possible that the reorganized auditory circuits and plasticity are related to development of irreversible tinnitus.

  • Middle nasal valve collapse: A way to resolve

Lecturing ENT in Croatia and Portugal ( Medical School University of Zagreb and Porto). Membership in SPORL, APO, EAFPS, IAPO and RSE. Publications and respective citations in ResearchGate.

    Abstract

    Middle nasal valve collapse is a partial or complete collapsing of soft structures of nasal pyramid, due to negative intranasal pressures resulting in complete anterior nasal obstruction of airflow. Even though is relatively common, it is often misdiagnosed or neglected in diagnosis. There are too many suggestions of surgical resolution of the problem, giving an idea that all of them are actually only partially or insufficiently resolving the problem. In this paper a possible solution of middle nasal vault collapse was presented. A triangle cartilage grafting with respecting of anatomical and functional principles was suggested. An open rhinoplasty approach by its large exposure was, in our hands, the election method for resolving the problem.

  • Analysis of three-dimensional movement of immobile vocal fold using 3DCT for correct diagnosis and surgical strategy planning

    Shinjyuku Voice Clinic
    Japan
    Biography

    Ryoji Tokashiki graduated from Tokyo Medical University in 1990 and has been a professor at Tokyo Medical University since 2008. In 2010, he opened his own practice, “Shinjyuku Voice Clinic”, focusing on voice disorders. He performs over 200 voice surgeries for unilateral vocal fold paralysis (UVFP) and spasmodic dysphonia annually and has achieved good outcomes. He also performs over 500 office surgeries annually for vocal fold lesions, such as polyps, nodules, cysts, and injection laryngoplasty. His practice also treats many patients with functional voice disorders, including stuttering. He uses 3DCT to analyze three-dimensional movement in cases of immobile vocal fold, in which the actual movement cannot be determined by endoscopy because of the two-dimensional nature of the technique. He is currently interested in analyzing brain activity of functional dysphonia, spasmodic dysphonia and stuttering using functional MRI.

    Abstract

    This lecture will focus on three-Dimensional (3D) movement of the immobile Vocal Fold (VF) determined using three- Dimensional Computed Tomography (3DCT). As endoscopic findings reflect only two-dimensional movement of the VF, it is impossible to make a correct diagnosis using this method. The cases that will be presented will include not only Unilateral Vocal Fold Paralysis (UVFP) but also arytenoid dislocation, laryngeal scarring, and other status. The main conditions are outlined below. The 3D findings provide new information and are useful in surgical treatment planning. UVFP Even in cases of light UVFP, the paralyzed arytenoids are passively displaced cranially on phonation. Number of surgical procedures are available for UVFP, including injection laryngoplasty and type 1 thyroplasty. However, better voice quality can be acquired by “Arytenoid Adduction (AA)”, because it is the only method that can resolve this passive movement. Some specific types of UVFP, such as Adductor Branch Paralysis (AdBP), will also be presented. Arytenoid Dislocation (AD) Diagnosis of AD requires a good understanding of the complex 3D arrangement of the arytenoid cartilage. AD is commonly divided into two types, i.e., posterior and anterior dislocation. 3DCT analyses indicated that posterior AD is very rare and is often misdiagnosed as AdBP and vice versa. We found two types of anterior AD, i.e., cranial and caudal AD. The VF in cases of caudal AD is located at the mid-position. These patients show only mild vocal symptoms and are sometimes misdiagnosed as having medial UVFP. Other types of immobile VF There are many rare and interesting causes of immobile VF, including scarring after intubation or trauma, fracture, congenital conditions, and various other reasons. Endoscopy in not useful for understanding the condition of a patient’s larynx, while 3DCT can reveal the actual status in such cases.

    Biography

    Dr. Amira N Al Hail is senior consultant and head of department in Otorhinolaryngology, head and neck surgery in AlWakra Hospital which is one of the facilities of Hamad Medical Corporation in Qatar. She completed Fachartz in Otolaryngology, Muenster, Germany since 2007. She is Assistant Professor of clinical otolaryngology in Well Cornel College of Medicine-Qatar since 2016, and she is mentor and examiner in ACGME Accredited Arab Board Residency Program in ORL-HNS in Qatar as well as in medical college, University of Qatar. She had number of publications in many of reputed Journals and she is a member of different scientific and educational committees in Hamad Medical Corporation.

    Abstract

    Background: Cholesteatoma presents behind an Intact Tympanic Membrane (ITMC) and the underlying mechanism of its development is controversial. The aim of this presentation is to describe clinical features, pathogenesis (congenital versus acquired origin) and surgical results of adult patient affected by ITMC. Case report: Thirty-nine years old Pakistani female presented to Ear, Nose and Throat outpatient clinic in AlWakra Hospital, Hamad Medical Corporation in Qatar, suffered from right sided hearing impairment. The patient underwent myringotomy and grommet insertion on the same ear two years before in a private Hospital, and she attended regular follow-up till the grommet was dropped out. On examination there was a dull right tympanic membrane. Facial movements were intact and fistula test was negative. Audiometric test showed right-sided conductive hearing loss, around 40 dB on the speech frequency. CT scan of the temporal bone showed there was soft tissue density mass lesion occupying the right middle ear cavity (epitympanum and mesotympanum) destroying the bony ossicles, lateral wall of bony cochlea and lateral semicircular canal as well as the bony part facial canal. The tegmen tympani and tympanic membrane looks intact. Exploration of the right mastoid and middle ear showed cholesteatoma involving attic and aditus antrum. The stapes and incus were absent, there was erosion of lateral semicircular canal with fistula and destruction of bony canal of vertical part of facial nerve. Right-sided radical mastoidectomy with canal wall down procedure had been performed. The patient developed good postoperative recovery. Conclusion: ITMC in adults may have both congenital and acquired origin. In the above described patient, there is no clear evidence whether the cholesteatoma was congenital in origin or it might develop after grommet insertion.

    Abstract

    Background: Subglottic stenosis is children a challenging condition to the otolaryngologist. High-grade subglottic stenosis (grades III, VI cotton Mayer grading) in which the tracheal narrowing is > 70 % have been treated traditionally with open techniques namely laryngotracheoplasty or cricotracheal resection. Recent advances in endoscopic management and success in treating low-grade stenosis has led surgeons to try endoscopic intervention for high grade stenosis. Currently there are no guidelines in regards to the number of endoscopic intervention needed to consider success. Objectives: To review endoscopic management of highgrade subglottic stenosis and the number of interventions required achieving decannulation. Methods: A five-year retrospective review of patients diagnosed with high grade subglottic (grades III & IV) stenosis treated endoscopically in comparison with same treatment for low grade stenosis at King Abdulaziz University Hospital (KAUH), Jeddah, Saudi Arabia. Results: 37 of 46 subglottic stenosis classified as high grade subglottic stenosis. The mean rank of interventions among Grade III or IV was significantly greater than mean rank of grade I or II (p=0.001). Most of high-grade stenosis patients who were tracheostomy-dependent required open surgical technique to achieve decannulation. Conclusion: Open surgical techniques offer advantages for the cure of high-grade subglottic stenosis. Endoscopic intervention is effective when used for low-grade stenosis with low rate of revision.
