ABSTRACT
OBJECTIVES: In this study, we retrospectively evaluated the orbital and ocular dimensions using computed tomography (CT) scans in healthy adults. MATERIALS AND METHODS: This retrospective study included 302 Turkish adult individuals aged 20-76 years (158 males and 144 females), who underwent paranasal sinus or craniofacial CT due to headache or suspicion of sinusitis, but abnormal orbital or cranial CT findings were not detected. Linear and volumetric measurements of the orbital structures were performed in the sagittal, coronal, and axial planes on CT slices. The volume was estimated in cubic centimeters using the equation of the ellipsoid method. A total of 34 parameters were measured from both eyes of each individual using 14 different anatomical landmarks and analyzed by gender and age. RESULTS: Parameter values of orbital structures in males and females are shown in millimeters or cubic centimeters. In most of the 34 parameters that we evaluated, it was seen that males had statistically significant higher mean values than females (P < 0.05). Also, there was no statistically significant difference between the measurements of right and left orbits. The correlation with age was varied according to the 34 parameters. Interestingly enough, there were no statistically significant differences between the two genders for extraocular muscles thickness (except superior muscles group thickness-SMT) and left optic nerve thickness (LOT) (p > 0.05). The mean right superior muscles group thickness was 5.35 ± 0.85 mm in the male subjects and 4.64 ± 1.10 mm in the female subjects (P < 0.001). The mean left superior muscles group thickness (LSMT) was 5.28 ± 0.88 mm in the male subjects and 4.67 ± 1.16 mm in the female subjects (P < 0.001). The mean LOT was 6.15 ± 0.97 and 5.88 ± 1.07 mm in males and females, respectively (P = 0.099). CONCLUSION: This study can be applied to the standardization of orbital morphometry in healthy adults.

A 9-year-old male patient complaining of seizure attack was admitted to the neurosurgery department. Radiologic investigations revealed a 5-cm-long metallic sewing needle extending from the right frontal cortex to the right lateral ventricle. Burr hole surgery was performed and the needle was grasped with biopsy forceps and removed with endoscopic guidance. The patient recovered without any complications.

In this clinical study, to determine the therapeutic efficacy of interferon (IFN) treatment for Peyronie's disease, we applied interferon alpha-2A (IFN alpha-2A) intralesionally in the treatment of Peyronie plaques in 15 patients and results were evaluated by magnetic resonance imaging (MRI). Patients whose plaque sizes were 0.5 and 1 cm responded better to the treatment. There was about a 90% lessening in the sizes of the plaques of 1.5 cm, 83.3% of 2 cm, as the ones which were 0.5 cm and 1 cm disappeared completely after treatment. As a conclusion, the treatment of Peyronie's disease with IFN alpha-2A is effective and side effects are minimum.
