Laryngopharyngeal reflux (LPR) is becoming recognized as a clinical entity with a variety of presentations distinct from those of gastroesophreflux disease (GERD). However, much uncertainty remains as to what is considered pathologic versus physiologic reflux. The aim of the study was to determine the normal range of pharyngeal reflux (PR) occurring in(More)
Our purpose was to assess the use of magnetic stimulation for measuring conduction time of the recurrent and superior laryngeal nerves In 10 normal volunteers (7 male, 3 female). Subjects underwent laryngeal electromyography and magnetic stimulation of the vagus nerve bilaterally at the mastoid tip with a figure 8 coil. Mean muscle response latencies were(More)
Sarcoidosis is a global disorder whose breadth of organ involvement can often be underappreciated. Head and neck manifestations include involvement of the skin, salivary glands, sinonasal cavity, and larynx. Of cases of upper airway sarcoidosis, laryngeal sarcoidosis and airway compromise portend a greater risk of fatal outcomes. People representing all(More)

OBJECTIVES We evaluated the presence and pattern of ProEx C stain, a marker for the proliferative capacity of cells, in laryngeal tissues, including benign, malignant, and recurrent respiratory papilloma (RRP) specimens, and compared it to hematoxylin and eosin staining for the presence of dysplasia. METHODS We performed a retrospective study with chart(More)
