The interactions of the intrinsic laryngeal muscles (ILMs) in controlling fundamental frequency (F0) and glottal posture remain unclear. In an in vivo canine model, three sets of intrinsic laryngeal muscles-the thyroarytenoid (TA), cricothyroid (CT), and lateral cricoarytenoid plus interarytenoid (LCA/IA) muscle complex-were independently and accurately(More)
OBJECTIVES/HYPOTHESIS Evaluate the effects of asymmetric superior laryngeal nerve stimulation on the vibratory phase, laryngeal posture, and acoustics. STUDY DESIGN Basic science study using an in vivo canine model. METHODS The superior laryngeal nerves were symmetrically and asymmetrically stimulated over eight activation levels to mimic laryngeal(More)
OBJECTIVES/HYPOTHESIS The posterior cricoarytenoid (PCA) muscle is the sole abductor of the glottis and serves important functions during respiration, phonation, cough, and sniff. The present study examines vocal fold abduction dynamics during PCA muscle activation. STUDY DESIGN Basic science study using an in vivo canine model and human subjects. (More)
Seven patients with reacting perforating collagenosis (RPC) were diagnosed from 1974 to 1982. Experimental production of lesions in two patients confirmed the contributory role of superficial trauma. The pathogenesis of RPC involves transepithelial elimination of altered collagenous bundles. This process may be observed in a wide variety of disparate skin(More)
OBJECTIVES/HYPOTHESIS Medialization thyroplasty (MT) is commonly used to treat glottic insufficiency. In this study, we investigated the phonatory effects of MT implant medialization depth and medial surface shape. METHODS Recurrent laryngeal nerve (RLN) and vagal paralysis were simulated in an in vivo canine. A type 1 MT was performed using a silicone(More)
OBJECTIVES/HYPOTHESIS Evaluate the influence of asymmetric recurrent laryngeal nerve (RLN) stimulation on the vibratory phase, acoustics and aerodynamics of phonation. STUDY DESIGN Basic science study using an in vivo canine model. METHODS The RLNs were symmetrically and asymmetrically stimulated over eight graded levels to test a range of vocal fold(More)
Of the nine missiles that landed on the city of Tel Aviv-Jaffa during the Persian Gulf war, three fell in heavily populated areas. As a result 192 people were sent to hospital and 1,663 (520 families) were left homeless. These were seen and evaluated near the site of the blast by a municipal multidisciplinary team and then sent to one of 15 hotels in and(More)
