Introduction:Pilonidal sinus disease(PSD) is a chronic, progressive inflammatory disease,occurring in the sacrococcygeal region, manifested by an abscess or a draining sinus, disrupting the quality of life.Despite the fact that many treatments have been defined, the search for the most appropriate and ideal treatment is still ongoing since the rates of disease are still high.

Objective:We prefer minimal invasive treatment protocols increasingly because of the high rates of complications and onset in the surgical treatment of this disease.Phenol injection is a minimal invasive method and is applied in two different forms, crystal and liquid.In this study we compared the complications, difficulty of applying, effectiveness of crystal and liquid phenol.

Material and Methods:Our study includes a total of 112 children who were applied phenol in our clinic for PSD between 1 August 2022 and 1 August 2023.Patients were randomly divided into two groups.Patients’ demographic data,complications,post-operative abscess formation,chemical burns in their follow-up were recorded prospectively.The results were compared statistically.

Results:The average age of the crystal phenol group(Group 1)was 16.14±1.58,while the average age in the liquid phenolic group(Group 2)was 15.66±1.52.The group 1 had a history of pre-operative abscess drainage at 49.5% and the group 2 at 50.5%.The average number of holes in the group 1 was 1.14≤0,52 while group 2 had an average of 1.11±0,56.Groups 1 and 2 were assessed as clinically significant due to the severity of the concomitant complication however statistically no difference in soft tissue necrosis(p<0.05).

Conclusion:Successful results in the treatment of PSD are obtained with the application of phenol in both crystallized and liquid forms.We don't recommend liquid phenol for reasons such as the difficulty in use, the difficulties of providing the safety of patients and doctors.
