Effect of tympanostomy tube surface on occlusion.

Objective: Premature tympanostomy tube (TT) occlusion frequently leads to TT replacement surgery. TT surface preparations have been suggested as a means of reducing TT occlusion. The purpose of this study is to determine if commercial TT compositions or surface preparations impact the rate of TT occlusion using an in vitro model.

Analysis of flap tension in surgical rejuvenation of the midface: a cadaver study.

Objective: To determine the flap tension present for 2 different surgical approaches for midface lifts and whether a gingivobuccal incision for release of the midface periosteum will diminish the resultant load on the midface flap.

Study Design: Cadaver study.

Setting: Anatomy laboratory at the University of Florida.

Development of a calcium alginate tympanostomy tube.

Objectives/hypothesis: Tympanostomy tubes (TTs) are prone to complications resulting in part from the unpredictable duration that the TT remains in the tympanic membrane. General anesthesia may be necessary to remove TTs that fail to extrude. The purpose of this study was to develop a TT that could be dissolved on demand but remain functional with exposure to common otologic exposures.

In vitro testing of tympanostomy tube occlusion.

Objective: Tympanostomy tubes (TTs) are commonly rendered nonfunctional by mucus plug formation. The purpose of this study was to determine whether an in vitro model could be developed to assess TT plug formation with results consistent with human trials.

Study Design: An ear chamber was designed to mimic middle ear air and mucus flow conditions in post-TT otorrhea.
