Squamous epithelium in the middle ear and sinus.
This study has been performed between December 1990-March 1991 in the Microsurgery laboratory of the Marmara University Hospital. Twelve healthy albino guinea pigs were used as a study group while the control group consists of three animals. The potentials for cholesteatoma formation of the squamous epithelium, namely the squamous epithelium of the posterior superior part of the external ear canal skin and normal skin, were investigated. Among 24 subjects who were implanted by canal skin, cholesteatoma was formed in 21 of them. Likewise, 19 of 24 animals implanted by normal skin came out with cholesteatoma formation. Between these two types of epithelium, there is no statistical difference in cholesteatoma formation (p > 0.5).

Intraocular pressure changes in the vitreon study.
BACKGROUND AND OBJECTIVE: To detect the effect of Perfluoroperhydrophenanthrene (vitreon) on intraocular pressure (IOP) changes. PATIENTS AND METHODS: One hundred-five eyes with proliferative vitreoretinopathy undergoing vitrectomy using vitreon as an intraoperative surgical adjunct were randomized to 2 groups. Vitreon was completely removed in 43 eyes (Group A) at the end of operation while it was left intravitreally in 62 eyes (Group B) for 4 weeks. Patients were followed for at least 18 months. RESULTS: During the first postoperative week, 6 eyes (14%) in Group A and 14 eyes (22%) in Group B had IOP of 23 mm Hg or more (P = .393) while no eyes in either group had hypotony. At the last follow-up 2 eyes (5%) in Group A and 6 eyes (10%) in Group B showed chronic hypotony (P = .561). CONCLUSION: Although postoperative chronic hypotony risk increased twofold by vitreon when it was left intravitreally for 4 weeks, this difference was statistically insignificant. Vitreon can be used as a vitreous substitute for 4 weeks in this regard.
