What is a pilonidal sinus?
A pilonidal sinus (PNS) is a small hole or tunnel in the skin. It may fill with fluid or pus, causing the formation of a cyst or abscess. It occurs in the cleft at the top of the buttocks. A pilonidal cyst usually contains hair, dirt, and debris. It can cause severe pain and can often become infected. If it becomes infected, it may ooze pus and blood and have a foul odor.
A PNS is a condition that mostly affects men and is also common in young adults. It’s also more common in people who sit a lot, like cab drivers. pilonidal sinus treatment in Delhi
What are the causes of pilonidal sinus disease?
The exact cause of this condition isn’t known, but its cause is believed to be a combination of changing hormones (because it occurs after puberty), hair growth, and friction from clothes or from spending a long time sitting.
Activities that cause friction, like sitting, can force the hair growing in the area to burrow back under the skin. The body considers this hair foreign and launches an immune response against it, similar to how it would react when dealing with a splinter. This immune response forms the cyst around your hair. Sometimes a person may have multiple sinuses that connect under the skin
Identifying a pilonidal sinus and recognizing signs of infection
You may not have any noticeable symptoms at first other than a small, dimple-like depression on the surface of your skin. However, once the depression becomes infected, it will quickly develop into a cyst (a closed sac filled with fluid) or an abscess (a swollen and inflamed tissue where pus collects).
The signs of an infection include:
pain when sitting or standing
swelling of the cyst
reddened, sore skin around the area
pus or blood draining from the abscess, causing a foul odor
hair protruding from the lesion
formation of more than one sinus tract, or holes in the skin
You may also experience a low-grade fever, but this is much less common.
How are pilonidal sinuses treated?
Conservative treatment
If your case is diagnosed early on, you aren’t experiencing severe pain, and there’s no sign of inflammation, it’s likely that your doctor will prescribe a broad-spectrum antibiotic. A broad-spectrum antibiotic is an antibiotic that treats a wide range of bacteria. It’s important to realize that this won’t heal the sinus tract, but it will give you relief from the infection and discomfort. Your doctor will recommend that you get a follow-up exam, regularly remove hair or shave the site, and pay particular attention to hygiene.
Lancing
This procedure alleviates symptoms from an abscess, or a collection of pus inside the sinus. Before this procedure, your doctor will give you a local anesthetic. They will then use a scalpel to open the abscess. They will clean away any hair, blood, and pus from inside the abscess.
Your doctor will pack the wound with a sterile dressing and allow it to heal from the inside out. The wound usually heals within four weeks, and many people don’t require any further treatment.
Phenol injection
For this type of treatment, your doctor will first give you a local anesthetic. They will then inject phenol, a chemical compound used as an antiseptic, into the cyst. This procedure may need to be repeated several times. Eventually, this treatment will cause the lesion to harden and close.
This treatment has a very high recurrence rate. Therefore, it’s uncommon in the United States. Doctors turn to surgery as the treatment of choice in some cases.
