The beginnings and development of endoscopic sinus surgery in Venezuela was due solely to the tenacity of Dr. De Sousa. After having completed his postgraduate studies in Caracas, he traveled to the EE.UU in the late 80's in search of knowledge in the novel discipline back then of Endoscopic Sinus Surgery.
Prior to the adaptation of endoscopic approaches for sinonasal pathology, patients regularly endured significant morbidity from open approaches to the sinonasal cavity that was often fraught with failure.
After gaining experience with endoscopic surgical techniques, the first endoscopic surgical course was held at Johns Hopkins Medical Center in 1985, directed by Drs. David Kennedy and Heinz Stamberger (Graz, Austria).
Amid the growth of the techniques followed the publication of landmark papers delineating the theory, diagnostic evaluation and technique of functional endoscopic sinus surgery (FESS) and subsequent animal experiments demonstrating the validity of the concept.
When Dr. Kennedy left Johns Hopkins in 1991 to become the chair at the University of Pennsylvania, Johns Hopkins did not formally have a division of rhinology. Nevertheless, Johns Hopkins was clearly established as the leading institution within the continually developing subspecialty of rhinology.
Endoscopic Sinus Surgery from that moment, would demonstrate progressively worldwide the validity of their concepts in the surgical treatment of the inflammatory disease of the paranasal sinuses and years later in the surgical management of different sinonasal pathologies (Tumors), as well as the development of the trans-nasal endoscopic approaches of extra-sinonasal diseases (Skull base and Orbital).
Dr. De Sousa during those years would be one of the first Latin American witnesses of these wonderful advances that will revolutionize the otorhinolaryngology of the 20th century.
