Abstract
Perilymphatic fistulas (PLF) and superior semi-circular canal dehiscence syndrome (SCDS) are 2 conditions that can present with sound and/or pressure-induced vertigo. PLF should be suspected in cases of trauma or surgery, while a spontaneous PLF is a diagnosis of exclusion. Research is ongoing to identify an ideal biomarker for perilymph. The diagnosis of SCDS continues to evolve with further research into vestibular-evoked myogenic potentials, electrocochleography, and higher resolution CT imaging. Treatment advances include the transmastoid approach, smaller middle fossa craniotomies, and usage of endoscopes. Temporal bone studies have furthered the understanding of pressure dynamics within the ear and how this relates to recommendations for repair versus alternative treatments such as round window plugging.
期刊介绍：
Material for each volume in this series has been skillfully selected to document the most active areas of otorhinolaryngology and related specialties, such as neuro-otology and oncology. The series reproduces results from basic research and clinical studies pertaining to the pathophysiology, diagnosis, clinical symptoms, course, prognosis and therapy of a variety of ear, nose and throat disorders. The numerous papers correlating basic research findings and clinical applications are of immense value to all specialists engaged in the ongoing efforts to improve management of these disorders. Acting as a voice for its field, the series has also been instrumental in developing subspecialities into established specialities.
