Abstract

Objectives : This study was aimed to investigate soft tissue reaction such as inflammation, immune reaction of rabbit larynx to implanted foley catheter. Methods : After 8 rabbits were anesthetized, their thyroid cartilage and trachea were exposed through a skin incision and a 6 French foley catheter was inserted into the thyroid cartilage via cricothyroid membrane and ballooned with normal saline (0.1 mL). The other end of catheters were ligated and cut. The wound was closed keeping catheter under the skin. Two rabbits were used as normal control Larynges were removed for pathologic examination at 4weeks and 8 weeks of the study respectively, Results : Ten rabbits were euthanized for gross and pathologic examination (5 rabbits after 4 weeks and 5 rabbits after 8 weeks). All rabbits survived the study periods and inflammations or foreign body reactions were minimally found on pathologic examinations. Conclusions : Foley catheter could be useful and safe material for vocal fold medialization in rabbit models.
