Aviv advocated for widespread in-office screening for esophageal cancer using transnasal esophagoscopy (TNE),[3] and originated Flexible Endoscopic Evaluation of Swallowing with Sensory Testing (FEESST).
[4] In 1997, Aviv was appointed to be a Technical Advisor to the Agency for Health Care Policy and Research (AHCPR) branch of the Department of Health & Human Services, now Center for Medicaid and Medicare Services (CMS) regarding the diagnosis and treatment of swallowing disorders in older patients, which dovetailed with his appointment from 1996–2001 to the Functional Outcomes Task Force on Dysphagia by the American Speech and Hearing Association.
He represented the American Academy of Otolaryngology–Head and Neck Surgery as Chairman of its Committee on Speech, Voice and Swallowing Disorders from 1997 to 2003.
One of the significant accomplishments during these years was the development of a new series of CPT codes for office-based evaluation and treatment of swallowing disorders which carry on to this day.
[5] He has also published numerous journal articles related to FEESST, TNE, acid reflux disease, and cough.
