Objectives: To correlate topical steroidal treatment of stenosed foreskin with the different degrees of glans exposure and the length of time the ointment is applied.
Materials and Methods: We studied 95 patients with phimosis, divided according to the degree of foreskin retraction. Group A presented no foreskin retraction, group B presented exposureof only the urethral meatus, group C presented exposure of half of the glans, and group D presentedexposure of the glans, which was incomplete because of preputial adherences to the coronal sulcus.
Patients were submitted to application of 0.05% betamethasone ointment on the distal aspect of theprepuce twice daily for a minimum of 30 days and a maximum of 4 months.
Results: Of 95 patients, 10 (10.52%) abandoned the treatment and 15 patients in groups C and D were excluded from the study. Among the remaining 70 patients, only 4 patients (5.7%) ingroup A did not obtain adequate glans exposure after treatment. In group A (38 patients), fully retract-able foreskins were obtained in 19 patients (50%) after 1 month of treatment. In group B (28 patients),fully retractable foreskins were obtained in 18 patients (64.2%) after 1 month.
Conclusions: Treatment was successful in 94.2% of patients, irrespective of the type of fore- skin anatomy. The improvement may require several months of treatment. Patients with impossibilityof urethral meatus exposure present around 10% treatment failure.

In Australia at the beginning of the 1990s, Kikiros et al. (10) attested to the efficacy of topical corti- costeroids in the treatment of preputial stenosis. Since then, several authors have shown satisfactory results (67% to 95%) with the topical use of betamethasone, clobetasol, sodium diclofenac, 0.05% mometasone furoate and triamcinolone acetonide (8-10).
