Evaluation of Vulvar Disorders by Vulvoscopy Index and N-S-P Scheme Using Three Rings Vulvoscopy (TRIV)

Area of Science:

• Gynecology
• Dermatology
• Medical Imaging

Background:

• The TRIV (Three Rings of the Vulva) technique divides the vulva into three distinct zones.
• Objective tools like the Vulvoscopy Index and N-S-P scheme enhance systematic vulvoscopy and data management.

Purpose of the Study:

• To evaluate the effectiveness of the TRIV technique combined with the Vulvoscopy Index and N-S-P scheme for diagnosing vulvar disorders.
• To establish the diagnostic accuracy and predictive values of these tools in a clinical setting.

Main Methods:

• TRIV was performed on 100 women with vulvar complaints and 100 asymptomatic controls.
• Findings were documented using the N-S-P scheme and Vulvoscopy Index, with biopsies taken for specific lesions.
• Vulvar disorders were categorized based on histological and clinical findings.

Main Results:

• The N-S-P scheme identified common formulas for normal vulva (N-N-N), vulvar dermatoses (P-P-P), and impaired vulvar skin (N-S-N).
• The Vulvoscopy Index showed high diagnostic accuracy (98.50%), sensitivity (100%), and specificity (96.51%) for detecting vulvar disorders.
• Mean Vulvoscopy Index values varied significantly across different disorder categories.

Conclusions:

• The Vulvoscopy Index is a significant predictor of vulvar disorders.
• The N-S-P scheme facilitates objective and systematic documentation for monitoring vulvar changes.
• TRIV aids in the early prevention of vulvar dermatosis, a risk factor for malignancy.
