The "take rate" and audiometric results following inlay cartilage tympanoplasty or underlay tympanoplasty were similar. Inlay butterfly cartilage tympanoplasty did not require general anesthesia, was less expensive, and more comfortable to the patient.

The glottic angle can be reliably measured from flexible endoscopic images and angular velocities of vocal fold abduction and adduction can be determined from analysis of sequential video frames. Accuracy is significantly enhanced by correction of distortion in the images. This approach holds promise for objective characterization of vocal fold function in patients with a variety of disorders.
