Objectives:To evaluate prospectively the relative usefulness of color Doppler and gray scale sonography in differentiating benign from malignant ovarian masses and evaluation of scoring systems Sassone and Alcazar for differentiating benign from malignant ovarian masses.Methods:Study was conducted during the period of Jan 2006 to Oct 2007 in department of obstetrics and gynaecology, New civil Hospital, Surat. The study was conducted mainly with the help of department of radio-diagnosis. The study include 100 patient clinically suspected to have ovarian neoplasm and referred to department of radio-diagnosis where evaluation with Ultrasonography and Doppler was done. The efficacy of scoring systems were evaluated by histopathological examination of mass or fine needle aspiration cytology or presence of malignant cells in ascetic fluid.Results:Sassone's scoring system was able to identify 72 out of 78 benign masses and 18 out of 22 malignant masses.where as Alcazar system with use of colour Doppler was able to identify 75 out of 78 benign and 21 out of 22 malignant ovarian masses. Sensitivity and specificity of sassone is 81.8%,92.3% respectively, where as that of Alcazar is 95.5%, 96.2% respectively.Conclusion:Using both gray scale and colour Doppler in differentiating benign from malignant ovariam masses is giving results with more accuracy and Alcazar system is better performing than sassone's scoring systems.

Augmentation rhinoplasty can be carried out using a wide range of materials including autologous bone and/or cartilage as well as alloplasts. Use of biologic bone and cartilage grafts results in lower infection rates, but they are associated with long-term resorption and donor-site morbidity. Alloplastic materials, in particular silicone, have been associated in literature with extrusion, necrosis of the tip, mobility and deviation or displacement of the implant, immobile nasal tip and infection. However, they have the advantages of being readily available and easy to reshape with no requirement for harvesting autografts.Aim:To overcome these problems associated with silicone implants for which the authors have devised a novel technique, the “rideon technique”.Materials and Methods:The present study was carried out on 11 patients over a period of 4 years. The authors have devised a simple technique to fix the silicone implant and retain it in place. Restricting the implant to only dorsum avoided common complications related to the silicone implant.Results:The authors have used this technique in 11 patients with encouraging results. Follow-up ranged from 12 months to 36 months during which patients were assessed for implant mobility, implant extrusion and tip necrosis. There was no incidence of above mentioned complications in these patients.Conclusion:The “rideon technique” provides excellent stability to silicone implants and restricting the implant only to dorsum not only eliminates chances of tip necrosis and thus implant extrusion but also maintains natural shape, feel and mobility of the tip.
