The effect of the YK lens in keratoconus.

Purpose: To report the clinical results of the use of the YK contact lens (Lucid Co., Seoul, Korea) for keratoconus.

Methods: One hundred and twenty nine keratoconic eyes were fitted with a YK lens which has one base curve and three peripheral curves.

Analysis of the postoperative outcome in 405 cases of orbital fracture using 2 synthetic orbital implants.

The purpose of this study was to analyze the postoperative complications according to the location (floor/medial wall/floor and medial wall) of the orbital fracture of 405 patients during the past 10 years and to investigate the possible alterative data in postoperative outcome in change with the application of 2 synthetic orbital implants: porous polyethylene (Medpor) and hydroxyapatite (Biocoral). The medical records of 405 patients were reviewed especially for enophthalmos, diplopia, sensory disturbance in the area of distribution of the infraorbital nerve, and postoperative complications originated from the implanted material itself, from March 1993 to July 2003. Of the 405 patients, 214 patients were operated with porous polyethylene and 191 patients with hydroxyapatite.

Characterization of breast lesion using double phase Tc-99m Tetrofosmin scintimammography: comparison of visual and quantitative analyses.

Unlabelled: To compare the diagnostic performances of visual and quantitative indices of double phase Tc-99m Tetrofosmin scintimammography (TF-SMM) for the detection of breast cancer.

Methods: Double phase TF-SMM (early, 10 min; delayed, 3h) were performed after injection of 925 MBq of Tc-99m Tetrofosmin in 75 highly suspected breast cancer patients (malignant: 49, benign: 26). For visual analysis, five scoring method was used.

A report of 12 cases of basal cell carcinoma arising in lesions following laser therapy.

Since the latter half of the 1990s, laser treatment has become a common practice in Korea. A group of patients diagnosed as having basal cell carcinoma (BCC) also had a history of prior laser therapy performed on undiagnosed cutaneous lesions. Clinical and histologic evaluations of these cases were performed retrospectively.

A simple and quantitative method for three-dimensional measurement of normal smiles.

Smile reconstruction is one of the most challenging fields in plastic surgery. An understanding of the normal smile is essential in planning surgery for facial paralysis. The purpose of this study was to suggest a simple and quantitative method for the 3-dimensional analysis of smiles and to establish a basis for smile reconstruction in facial paralysis patients.

Treatment of atrophies secondary to trilinear scleroderma en coup de sabre by autologous tissue cocktail injection.

Background: The atrophies are left after regression of linear scleroderma "en coup de sabre." They are often irreversible and disfiguring. Several surgical techniques have been attempted to correct atrophies secondary to linear scleroderma en coup de sabre.
