Division of Pediatric Otolaryngology, The Children's Hospital of Philadelphia, and the Institute of Photochemistry and High Energy Radiation, National Institute of Nuclear Energy, Legnaro, Padua, Italy.
Objective: We investigated pressure-equalizing (PE) tubes made of biodegradable, absorbable material in an animal model.
Methods: PE tubes, made of poly-bis(ethylanate)phosphazene (PBE) were inserted in 55 ears of 28 Hartley guinea pigs, with survival times of 10, 30, and 60 days after tube insertion. In vivo reactions between the PBE-PE tube and the tympanic membrane (TM) were studied.
