  • CO2 laser in revision stapes surgery : Lasers and optical technology in otolaryngology
    1997
    Co-Authors: S. Jovanovic, U. Schönfeld, H. Scherer
    Abstract:

    Successful restoration of audition in revision stapedotomies involves precise identification and correction of the pathological condition without traumatizing the inner ear. Conventional surgical procedures often lead to unsatisfactory audition results and inner ear damages. In revision stapedotomy, the CO 2 laser provides the ear surgeon with three important advantages over the conventional technique: I. improved diagnostic and therapeutic precision, 2. better stabilization of the new prosthesis in the oval niche, and 3. reduction of inner ear trauma through non-contact atraumatic management. The surgical procedure of revision stapedotornies with the CO 2 laser is discussed, and case examples are used to illustrate the diversity of pathological conditions that can be treated by CO 2 laser surgery. Our experience with revision CO 2 laser stapedotomy suggests an improvement of postoperative audition compared to the conventional technique and demonstrates a significant elimination of sensorineural Deafness. The CO 2 laser enables the ear surgeon to precisely and reliably correct Conduction Deafness recurring after stapedotomy.

    Abstract:

    Successful restoration of audition in revision stapedotomies involves precise identification and correction of the pathological condition without traumatizing the inner ear. Conventional surgical procedures often lead to unsatisfactory audition results and inner ear damages. In revision stapedotomy, the carbon-dioxide laser provides the ear surgeon with three important advantages over the conventional technique: (1) improved diagnostic and therapeutic precision, (2) better stabilization of the new prosthesis in the oval niche, and (3) reduction of inner ear trauma through non- contact atraumatic management. The surgical procedure of revision stapedotomies with the carbon dioxide laser is discussed, and case examples are used to illustrate the diversity of pathological conditions that can be treated by carbon-dioxide laser surgery. Our experience with revision carbon-dioxide laser stapedotomy suggests an improvement of postoperative audition compared to the conventional technique and demonstrates a significant elimination of sensorineural Deafness. The carbon-dioxide laser enables the ear surgeon to precisely and reliably correct Conduction Deafness recurring after stapedotomy.

  • Highly biocompatible behaviour and slow degradation of a LDH (layered double hydroxide)-coating on implants in the middle ear of rabbits
    Journal of Materials Science: Materials in Medicine, 2015
    Co-Authors: Franziska Duda, Peter Paul Müller, Marc Kieke, Maria E. Schweinefuß, Florian Waltz, Muhammad Badar, Peter Behrens, Karlheinz Esser, Thomas Lenarz, Nils Kristian Prenzler
    Abstract:

    Chronic inflammation can irreversibly damage components of the ossicular chain which may lead to sound Conduction Deafness. The replacement of impaired ossicles with prostheses does not reduce the risk of bacterial infections which may lead to loss of function of the implant and consequently to additional damage of the connected structures such as inner ear, meninges and brain. Therefore, implants that could do both, reconstruct the sound Conduction and in addition provide antibacterial protection are of high interest for ear surgery. Layered double hydroxides (LDHs) are promising novel biomaterials that have previously been used as an antibiotic-releasing implant coating to curb bacterial infections in the middle ear. However, animal studies of LDHs are scarce and there exist only few additional data on the biocompatibility and hardly any on the biodegradation of these compounds. In this study, middle ear prostheses were coated with an LDH compound, using suspensions of nanoparticles of an LDH containing Mg and Al as well as carbonate ions. These coatings were characterized and implanted into the middle ear of healthy rabbits for 10 days. Analysis of the explanted prostheses showed only little signs of degradation. A stable health constitution was observed throughout the whole experiment in every animal. The results show that LDH-based implant coatings are biocompatible and dissolve only slowly in the middle ear. They, therefore, appear as promising materials for the construction of controlled drug delivery vehicles.

  • Relief of Conduction Deafness in Progressive Deafness
    Journal of the Acoustical Society of America, 2020
    Co-Authors: Emanuel M Josephson
    Abstract:

    Data presented before this Society almost a decade ago made it clear that disease changes in the eardrum in progressive Deafness contribute to the loss of hearing by increasing their resistance to the transmission of sound into the middle ear. This increased resistance can be eliminated by incision or excision of the eardrum. Further studies have shown that the results obtainable by the slight and simple operations on the eardrums fully equal those obtained by the grave and dangerous Sourdille “fenestration” operation or its various modifications. These operations do not effect a cure of the Deafness but merely offer relief and temporary improvement of hearing. The disease process that causes the Deafness continues to operate unless discovered and arrested. The effect of incision in various parts of the eardrum on the hearing raises the interesting acoustical problem of the exact mode of its transmission of sound. It raises the question whether the tympanic membrane may not be considered as consisting of ...
