What is phenol treatment?
Hair and debris are cleared from tracts in the natal cleft; phenol acts on the tract lining to support closure.
Who may be suitable?
It may be considered for pilonidal sinuses without an active abscess after examination.
- AssessmentTract number, extent and previous treatment are reviewed.
- AlternativesLaser and surgical options are compared for complex or recurrent disease.
When is other treatment needed first?
A painful, swollen abscess may require drainage first. Drainage near the anus needs assessment for other causes, including anal fistula.
How is it performed?
It is usually performed under local anaesthesia in a healthcare setting. Hair and debris are removed, surrounding skin is protected and phenol is applied. Reviews determine whether repetition is needed.
Risks and follow-up
Chemical burns, infection, discharge and recurrence can occur. One application cannot guarantee a lasting result.
- AftercareFollow the clinician’s hygiene, dressing and hair-control plan.
- ReviewSeek review for increasing pain, swelling, fever or foul discharge. Return to work depends on healing and job demands.
Frequently asked questions
Is phenol the same as laser?
No. Phenol acts chemically; laser uses energy. Selection follows examination.
