Care Designed Around the Individual Patient
Focused Evaluation
Your consultation begins with understanding what has been happening, how long symptoms have been present, and whether you have previously undergone drainage or surgery.
Personalized Treatment
Not every pilonidal cyst requires the same procedure. Treatment is selected based on whether there is an active abscess, chronic sinus tract, recurrent disease, or a non-healing wound.
Advanced Surgical Options
For appropriate patients, the surgeons offer a specialized flap-based approach designed to remove diseased tissue and reconstruct the area with a closed repair.
Continued Follow-Up
Treatment does not end when the procedure is finished. Follow-up allows the surgical team to monitor healing, answer questions, and address concerns early.
Specialized Pilonidal Cyst Treatment Close to Beverly Hills
A pilonidal cyst can begin as a small tender spot, dimple, or opening near the top of the buttock crease. Some people experience a sudden painful abscess. Others have a small opening that drains, closes temporarily, and then becomes irritated again weeks or months later.
Because pilonidal disease can behave differently from one person to another, treatment should not begin with a one-size-fits-all recommendation.
At Pilonidal Institute, Dr. Nasseri and Dr. Barnajian evaluate the entire pattern of disease. They consider whether this is your first infection, whether sinus tracts have developed beneath the skin, whether the condition has returned, and how any previous procedures may affect the next step.
The goal is to give you a clear explanation of what is happening and what treatment options make sense for your specific situation—not simply to recommend surgery to every patient.
Pilonidal Institute welcomes patients who live or work throughout Beverly Hills, including 90210, 90211, and 90212.

What Is Pilonidal Disease?
Pilonidal disease affects the skin and tissue in the crease between the buttocks, usually near the tailbone. It may appear as one or more small pits in the skin, a painful lump, an opening that drains, or a channel beneath the skin known as a sinus tract.
Hair, skin debris, fluid, and bacteria can collect within these openings. When infection develops, the area may become swollen, red, painful, or filled with pus. This collection is known as a pilonidal abscess.
Some pilonidal openings remain quiet and cause few symptoms. Others lead to repeated cycles of tenderness, drainage, bleeding, swelling, or infection. A person may feel better after an abscess drains, only to have the symptoms return because the underlying sinus tract is still present.
An in-person examination helps determine whether you have an active abscess, chronic pilonidal disease, a recurrent cyst, or another condition that may produce similar symptoms.
General medical references describe pain, swelling, drainage, bleeding, and abscess formation as common signs of symptomatic pilonidal disease. A painful abscess often requires drainage, while treatment for persistent or recurrent disease depends on the extent of the condition.

When Should You See a Pilonidal Specialist?
New Pain or Swelling
A tender lump, redness, or rapidly increasing discomfort near the tailbone may indicate that an abscess is developing.
Drainage or Bleeding
Pus, fluid, blood, staining on clothing, or an unpleasant odor may be signs of an infected or chronically draining sinus tract.
Repeated Flare-Ups
Symptoms that improve and then return may mean that the underlying pilonidal openings or tracts have not resolved.
Problems After Previous Surgery
A wound that has not fully healed, a new opening near an old scar, or recurring symptoms after treatment should be evaluated by a surgeon familiar with recurrent pilonidal disease.
Urgent Care
Seek prompt medical attention when pain or swelling is worsening quickly, drainage is accompanied by fever or chills, redness is spreading, or you feel generally unwell.
What to Expect During Your Consultation

We Listen to Your History
Your surgeon will ask when the symptoms began, how often they occur, whether the area has drained, and whether you have previously received antibiotics, drainage, wound care, or surgery.
It is also helpful to discuss how the condition affects sitting, work, exercise, sleep, driving, and other parts of your daily routine.

We Examine the Full Area
The examination looks for skin pits, sinus openings, drainage, inflammation, abscess formation, scarring, and the possible extent of disease beneath the skin.
For patients who have already undergone surgery, the location and condition of the existing scar are also important.

We Explain the Treatment Options
After the examination, your surgeon will explain what appears to be causing the symptoms and whether you may benefit from observation, abscess care, wound management, or a more definitive procedure.
The discussion should include why a treatment is being recommended, what alternatives may be available, how the wound will be managed, and what recovery may involve.
What to Expect During Your Consultation
Patients searching for pilonidal cyst treatment or pilonidal cyst surgery in Beverly Hills may encounter many different procedure names online. The appropriate option depends on what is found during the examination.

An Active Pilonidal Abscess
A painful, swollen collection of pus often needs to be opened and drained. Antibiotics may be recommended in certain circumstances, but medication alone may not eliminate a fully formed abscess.
Once the immediate infection has improved, your surgeon can determine whether additional treatment is needed to address the underlying disease.

Chronic or Recurrent Pilonidal Disease
Some patients experience an opening that repeatedly drains, becomes irritated, and then temporarily closes. Others have several painful infections over time.
When pilonidal disease continues to cause symptoms, a definitive procedure may be discussed to remove the diseased tissue and sinus tracts.

Disease That Returned After Treatment
Recurrence can occur after drainage or previous surgery. A recurrent case should be evaluated carefully rather than automatically repeating the same operation.
The surgeons assess the current openings, prior scar, depth of the buttock cleft, extent of inflammation, and condition of the surrounding tissue before recommending another treatment.

A Non-Healing Pilonidal Wound
A wound that remains open or continues to drain after surgery can be physically and emotionally exhausting.
Evaluation may identify persistent disease, tension on the wound, infection, hair entering the area, or an anatomic issue that is interfering with healing. The next step depends on what is causing the wound to remain open.

Pilonidal Openings Without Symptoms
Not every small pit requires immediate surgery. When there is no pain, swelling, infection, or drainage, monitoring and preventive care may be appropriate.
The treatment recommendation should always reflect the patient’s actual symptoms and examination—not simply the presence of a small skin opening.

Frequently Asked Questions
Is Pilonidal Institute located in Beverly Hills?
Pilonidal Institute’s physical office is located at 8635 W 3rd St in Los Angeles, near Beverly Hills.
Patients searching for a pilonidal cyst surgeon in Beverly Hills can visit the Los Angeles office for consultation, treatment, and follow-up. The institute serves patients from 90210, 90211, 90212, and surrounding Westside communities, but it does not represent this page as a separate Beverly Hills clinic.
What type of doctor treats a pilonidal cyst?
Pilonidal cysts may be treated by general surgeons or colorectal surgeons. A colorectal surgeon has specialized surgical training in diseases affecting the lower digestive tract and nearby anatomic region.
At Pilonidal Institute, patients are evaluated by Dr. Yosef Nasseri and Dr. Moshe Barnajian, colorectal surgeons with experience treating first-time, chronic, recurrent, and previously operated pilonidal disease.
Does every pilonidal cyst need surgery?
No. Treatment depends on whether the area is causing symptoms, whether an abscess or chronic sinus tract is present, and whether the condition keeps returning.
A small opening without pain, drainage, or infection may not require immediate surgery. A painful abscess may require drainage, while recurrent or chronically draining disease may lead to a discussion about definitive surgical treatment.
Your surgeon will make a recommendation after examining the area.
What should I do if my pilonidal cyst is painful and swollen?
A painful, swollen lump may be an abscess and should be evaluated promptly. An abscess frequently needs to be opened and drained because antibiotics alone may not resolve a collection of pus.
Contact the office for guidance. Seek urgent medical attention when symptoms are rapidly worsening or accompanied by fever, chills, spreading redness, or a feeling of being seriously unwell.
Can you evaluate a pilonidal cyst that returned after previous surgery?
Yes. Dr. Nasseri and Dr. Barnajian evaluate recurrent pilonidal disease and wounds that have not healed as expected.
The consultation considers the location of the previous scar, remaining pits or sinus openings, drainage, infection, wound condition, and underlying anatomy. Bringing prior operative reports, wound-care records, and relevant photographs can help the surgeons understand what treatment has already been performed.
What is flap-based pilonidal surgery?
Flap-based surgery removes the diseased cyst and sinus tracts and uses nearby healthy tissue to reconstruct and close the area.
At Pilonidal Institute, the surgeons offer a specialized flap-based outpatient approach for selected patients. Whether it is appropriate depends on the extent of the disease, infection, previous surgery, tissue condition, and individual health considerations.
Is pilonidal treatment performed as an outpatient procedure?
Many pilonidal procedures can be performed on an outpatient basis. The institute’s advanced flap-based procedure is described as an outpatient treatment for appropriate patients.
The exact setting depends on the planned operation, anesthesia, medical history, and surgeon’s recommendation. Patients receive preparation and transportation instructions before the procedure.
How long does recovery take after pilonidal surgery?
Recovery varies according to the procedure performed, the extent of disease, wound closure, previous treatment, overall health, occupation, and physical activity.
Your surgeon will explain when you may sit, drive, exercise, return to work, and resume other activities. Follow-up visits are important because they allow the team to monitor healing and adjust instructions as recovery progresses.
Do you treat patients from all three Beverly Hills ZIP codes?
Yes. Pilonidal Institute welcomes patients from 90210, 90211, and 90212, as well as neighboring areas.
All patients are seen at the institute’s physical office at 8635 W 3rd St, Los Angeles, CA 90048.
