Changes in ocular globe-to-orbital rim position with age: implications for aesthetic blepharoplasty of the lower eyelids.

Changes in the relationship of the anterior globe to the orbital rim, orbital fat, and cheek mass are examined in the present study. Two groups of individuals (N = 28) were studied, young versus old, using three-dimensional computer tomography. A computer-derived soft tissue reformat of the data allowed the anterior-posterior changes to be evaluated at the midpupillary plane.

The effect of skeletal remodeling on the nasal profile: considerations for rhinoplasty in the older patient.

The effect of continued differential growth of the adult male craniofacial skeleton on the nasal profile is examined in the present study. Two groups of individuals (N = 20) were compared, young (ages 16-23) and old (49-64). A three-dimensional CT scan was created for each individual in a standardized view.

A comparison of outcome criteria in the diagnosis of renovascular hypertension.

The outcome criteria used for the diagnosis of renovascular hypertension (RVHT) following renal revascularization have not been validated. Differing criteria of indeterminate accuracy have yielded conflicting conclusions concerning the prevalence and efficacy of treatment of RVHT. We compared the accuracy of conventional outcome criteria used in the diagnosis of RVHT to that of novel, ordered outcome analysis to determine whether such an analysis might provide a more consistent means of diagnosing RVHT.

Transcutaneous oxygen measurements predict healing of leg wounds with hyperbaric therapy.

Twenty-six patients with chronic leg wounds had transcutaneous oxygen measurements taken from the peri-wound area and a chest reference site before undergoing hyperbaric oxygen therapy in order to evaluate the utility of transcutaneous oxygen measurements in predicting the response of wounds to hyperbaric therapy. Wound scores and wound areas were determined before treatment and after 10 hyperbaric exposures. Patients whose wounds averaged a 5% or greater reduction in wound score per treatment were designated "responders.
