IMPORTANCE Eustachian tube (ET) dysfunction predisposes ears to otitis media, tympanic membrane retraction, retraction pocket and perforation, or cholesteatoma. OBJECTIVE To develop a method to quantitatively measure the eustachian tube (ET) component movements and their interactions captured by transnasal videoendoscopy of the ET during swallowing. DESIGN, SETTING, AND PARTICIPANTS A blind...

OBJECTIVE To describe a modified flap technique (MFT) involving the use of a false vocal fold flap for glottic reconstruction and the removal of arytenoid cartilage and to compare it with conventional frontolateral partial laryngectomy (FLPL) and laser cordectomy (LC). METHODS Twenty-eight MFT, 13 FLPL and 12 LC patients completed a standardised questionnaire for assessing aspiration, respira...

The use of high-speed videoendoscopy (HSV) in combination with image-processing techniques is the most promising approach to investigate vocal-folds vibration and laryngeal dynamics in speech and singing. The current challenge is to provide facilitative and informative playbacks for clinical and research purposes. We present three new facilitative playbacks using an optical-flow framework (OF)....
