  • TREATMENT OF TYMPANIC MEMBRANE RETRACTION WITH THE HOLMIUM LASER OTOLARYNGOLOGY-HEAD AND NECK SURGERY Kurokawa, H., Goode, R. L. 1995; 112 (4): 512-519

    Abstract:

    Politzerization, the Valsalva maneuver, and ventilation tube insertion are available treatments for tympanic membrane retraction. Ventilation of the middle ear cavity can correct tympanic membrane retraction in many cases, but not in all. Retraction may be localized or diffuse. This article describes experiments performed to evaluate a new method to "tighten" retracted or flaccid tympanic membranes with a holmium laser in a human temporal bone model. Ten temporal bones with mild-to-moderate retraction of the posterior superior quadrant or pars flaccida were treated with a series of laser pulses around and to the area of retraction. Umbo displacement before and after laser treatment was performed with a laser Doppler vibrometer to evaluate the effect on the acoustic function of the tympanic membrane. In all ears, the posterior superior quadrant retraction appeared to be completely corrected. Laser treatment of the posterior superior quadrant retraction produced improvement in umbo displacement below 1.0 kHz. After treatment of pars flaccida retraction, the configuration was improved a small amount; however, no increase in umbo displacement was found.
