Effectiveness of Methylene Blue Guidance in Total Excision of Pilonidal Sinus.

Does Intraoperative Methylene Blue Guidance in Pilonidal Sinus Surgery Really Effective in Total Excision of the Nest ?

Methylene bleu use in pilonidal sinus surgery is not an effective guidance as expected.

To study the potential benefits of intraoperative methylene blue use in pilonidal sinus surgery in detecting the borders of the disease, the histopathologic correlation between the specimen dyed by methylene blue and also the cavity excision specimen not dyed by methylene blue was investigated. The branches that distinctly exceeded the planned dyed excision borders will tried to be detected histopathologically, if any.
