Abstract Share this page

Ambulatory 24-h intraesophageal pH monitoring was performed in 32 patients with hoarseness, documented laryngeal pathologic findings or lesions, globus, and/or chronic cough. The laryngeal lesions included granulomas, stenoses, and carcinomas. Twenty-two (68.8%) of the patients had no symptoms specific for reflux. One-half of the patients underwent pH monitoring with a double probe, one probe being placed in the distal esophagus and the second being placed in the hypopharynx just behind the laryngeal inlet. Twenty-four (75%) of the patients had abnormal studies, i.e., significant reflux. Of those, 17 (70.8%) had upright reflux, 13 (54.2%) had supine nocturnal reflux, and 10 (41.7%) had both types. Seven of the 16 patients undergoing double-probe-type monitoring had reflux into the pharynx (43.8%). These data suggest that occult gastroesophageal reflux may be involved in the pathogenesis of many conditions commonly encountered in otolaryngologic practice.
