Procedures Performed

Common outpatient procedures performed at this ambulatory surgery center, based on reported specialties.

Orthopaedic Surgery6
Knee ArthroscopyA camera and small instruments are inserted through incisions the size of a buttonhole to repair cartilage, trim a torn meniscus, or remove loose fragments. Because the joint is not opened fully, recovery is far faster than traditional open knee surgery.Shoulder ArthroscopyUses a small camera and instruments through tiny incisions to repair the shoulder joint — commonly for impingement, labral tears, or damaged cartilage. Most patients go home the same day and begin physical therapy within the first week.ACL ReconstructionRebuilds the torn anterior cruciate ligament using a graft, since a fully torn ACL does not heal on its own. The surgery itself is outpatient, but returning to cutting and pivoting sports typically takes nine to twelve months of structured rehabilitation.Rotator Cuff RepairReattaches torn tendons in the shoulder to the bone. Pain relief often comes well before strength does — a sling is typical for several weeks and full recovery commonly takes four to six months, with physical therapy doing much of the work.Carpal Tunnel ReleaseCuts the ligament pressing on the median nerve at the wrist to relieve numbness, tingling, and night pain in the hand. The procedure takes about 15 minutes under local anesthesia. Night symptoms often improve immediately; grip strength returns over several weeks.Joint ReplacementDamaged joint surfaces are replaced with implants, most commonly at the knee or hip. Once exclusively a hospital procedure, selected healthy patients now have this done at surgery centers and go home the same day with a structured recovery plan.
Otolaryngology (ENT Surgery)6
Tonsillectomy / AdenoidectomyThe tonsils and sometimes the adenoids are removed for repeated infections or sleep-disordered breathing. Recovery is notably harder for adults than children, with significant throat pain for a week or more and a real emphasis on staying hydrated.Ear Tube PlacementTiny tubes are placed through the eardrum to drain fluid and ventilate the middle ear, most often for children with recurrent ear infections. The procedure takes about 10 minutes and the tubes usually fall out on their own within a year.Sinus Surgery (FESS)A camera and instruments passed through the nostrils open blocked sinus drainage pathways, with no external incisions. Considered for chronic sinusitis that has not improved with medication. Congestion often worsens briefly before it improves.SeptoplastyThe wall of cartilage and bone between the nostrils is straightened to improve airflow through a blocked side. It addresses breathing rather than external appearance, though it is sometimes combined with cosmetic reshaping.Turbinate ReductionSwollen tissue inside the nose is shrunk to improve airflow, frequently at the same time as septoplasty. Often the difference between a nose that is structurally straight and one that actually feels open.LaryngoscopyA scope examines the voice box and vocal cords, used for persistent hoarseness, difficulty swallowing, or throat pain that has not resolved. Small lesions can sometimes be biopsied or removed during the same procedure.
Interventional Pain Management6
Epidural Steroid InjectionsSteroid medication is injected near irritated spinal nerve roots to calm inflammation causing sciatica or arm pain. Often used to make physical therapy tolerable rather than as a standalone cure. There are limits on how frequently they can be repeated.Nerve Block InjectionsAnesthetic, sometimes with steroid, is injected around a specific nerve to interrupt pain signals. Used both to treat pain and to identify its source, since relief from a precisely placed block points to the nerve responsible.Radiofrequency AblationHeat generated by radio waves disables the small nerves carrying pain signals from an arthritic spinal joint. Relief commonly lasts six months to two years. Because the nerves regenerate over time, the procedure can be repeated.Spinal Cord StimulationA device delivers mild electrical pulses to the spinal cord to interrupt chronic pain signals before they reach the brain. A temporary trial period is done first, so you can judge the benefit before committing to a permanent implant.Joint InjectionsSteroid or lubricating medication is injected directly into an arthritic or inflamed joint. Image guidance is often used to confirm placement. Relief typically lasts weeks to months and can make physical therapy more productive.Trigger Point InjectionsA local anesthetic is injected into a taut, tender knot of muscle to break the spasm-and-pain cycle. The appointment takes minutes and you can usually return to normal activity the same day.
Plastic & Reconstructive Surgery6
Breast Augmentation / ReductionBreast size is increased by placing implants, or decreased by removing breast tissue and skin and repositioning the remaining tissue. Reduction is often performed to relieve back, neck, and shoulder pain caused by breast weight.RhinoplastySurgery that reshapes the nose by altering the bone and cartilage beneath the skin. It is performed to change appearance, to correct breathing problems caused by internal structure, or both. Swelling takes months to fully resolve.FaceliftLiposuctionFat is suctioned out from beneath the skin through small tubes called cannulas, reshaping a specific area such as the abdomen, flanks, or thighs. It targets localized deposits and is a contouring procedure rather than a method of weight loss.Wound ReconstructionRebuilds skin and underlying tissue where a wound is too large or too damaged to close directly. Surgeons move nearby tissue, or transfer skin and muscle from elsewhere on the body, to cover the defect. Often follows trauma, infection, or cancer removal.Skin GraftingHealthy skin is taken from one area of the body and transplanted to cover a wound or burn elsewhere. Both the graft site and the donor site need care, and the donor site is often the more uncomfortable of the two.
Podiatry (Foot & Ankle Surgery)6
Bunion Correction (Bunionectomy)The bony prominence at the base of the big toe is removed and the bone realigned, often with screws or plates. Recovery involves weeks in a protective shoe or boot, and swelling can persist for several months.Hammertoe CorrectionA toe permanently bent at the middle joint is straightened, sometimes with a temporary pin holding the correction. Considered when the toe rubs painfully in shoes or has developed calluses and sores.Plantar Fascia ReleaseThe tight band of tissue along the bottom of the foot is partially released to relieve stubborn heel pain. Reserved for cases that have not improved after months of stretching, orthotics, and other conservative treatment.Ankle ArthroscopyA small camera and instruments treat problems inside the ankle joint — impingement, loose fragments, or damaged cartilage — through incisions a few millimeters wide, avoiding a larger open exposure.Ingrown Toenail RemovalThe edge of a nail growing into the surrounding skin is removed under local anesthesia. When the problem keeps recurring, the nail-forming tissue at that edge is also treated so it does not grow back.Foot Fracture RepairBroken bones in the foot are realigned and stabilized with hardware so they heal in position. Because the foot bears your full weight with every step, alignment matters more here than the small bone size suggests.

I had surgery at East Hills Surgery Center for a hip replacement with Dr. Seiderman. Everyone on the staff there was wonderful! They were kind, caring and very considerate of my situation. Dr. Seiderman is terrific! I had my other hip done 6 years ago with him. Everything went well and I was up and about in no time. Thank you to everyone this at this facility for all your care and kindness.

What an amazing experience I had here. I had a cyst removal procedure and I was a bit nervous. The staff from the receptionist all the way to all the medical staff was beyond amazing. i was referred to Dr. Chorost by my primary care (Dr. Jack Li) and im glad I was. Dr. Chorost did an amazing job! Dr. Kelly was very helpful as well. Thank you to all the medical staff who made my procedure very easy and smooth and giving me the care I needed.

HORRIFIC !! This center is NOT the ambulatory center recommended by St Francis Hospital and Heart Center in Roslyn. There is a disclaimer at the very bottom of the East Hills Surgery Center website that says that the center is owned by physicians, who do NOT maintain the same standard of care offered at St Francis Hospital and Heart Center. The doctors make more money if they can convince patients to have their surgery at East Hills. It's all about the money. Catholic Health invested in the East Hills Surgery Center, but when I called St Francis Patient Care to complain about the care I received, I was told ST FRANCIS IS NOT AFFILIATED WITH THE EAST HILLS SURGERY CENTER AND DOES NOT OVERSEE THE QUALITY OF CARE PROVIDED TO PATIENTS. The connection is just financial. I should have left the center at 6:30am when the receptionist, Carol, told me and my family member that patients must enter WITHOUT a family escort. Family MUST wait in the waiting room. Why? Carol said it is an old rule from Covid that they just haven't gotten around to changing!! I asked who is responsible for changing the rule, and was told the board members of East Hills. Who are the board members? The doctors who own East Hills Surgery Center. Rules are made to protect doctors, NOT THE PATIENTS. The nurses at St Francis are top of their classes coming out of school, and are trained by outstanding nurses at the hospital. The nurses at East Hills almost killed me by overdosng me with Dilaudid- THREE TIMES, DESPITE MY WARNINGS TO THE ANESTHESIOLOGIST AND NURSES PRIOR TO SURGERY. I was so overdosed that I could not meet with the PT following my knee surgery, which began at 8am. At 5pm, I was still so drugged I couldn't move, but the nurses (Annie and Megan) said the center was closing, so they could wheel me out to the car, or call an ambulance to take me to St Francis Hospital. The nurse who first administered Dilaudid did not talk to me before administering the drug. When I asked what it was, she said "Dilaudid" I said, "it makes me sick and I specifically asked NOT TO RECEIVE DILAUDID." Her response? "OOPS" and giggles. Hours later, another nurse made the same mistake. When I vomited all over my newly bandaged knee, the nurses said they were not able to change the bandage. Had a family member been permitted to accompany me to the prep and recovery areas, this could have easily been avoided. THIS CENTER IS ABOUT PROFIT FOR THE DOCTORS, NOT PATIENT CARE. BEWARE.... stay away ! My doctor encouraged me to use East Hills saying, "this center is the ambulatory center for St Francis, all the same doctors, all the same nurses." NOT TRUE. NOT THE SAME POLICIES OR STANDARD OF PATIENT CARE.... JUST MORE PROFITABLE FOR PHYSICIANS. If your doctor pushes you to use East Hills, find another doctor !

WOW! An absolutely fantastic facility! Dr. Peter Stein, who performed my surgery is a world-class surgeon, super smart, compassionate, warm and very connective. The nurses that I had attending, Ashley and Lori were amazing professionals that made me feel incredibly comfortable. Everyone from the receptionist to the anesthesiologist were wonderful. I could not have had a better experience anywhere then at East Hills Surgery Center. I highly recommend state-of-the-art, immaculately clean establishment.

I had an absolutely pleasant experience having surgery here. From the front desk worker Alyssa checking me in with a smile on her face and being extremely helpful to all the staff in the back. Special shout out to Cassie, who was really fun and upbeat and cut my cast off and made me feel very comfortable and also to Ashley, who was my post-surgery nurse. She was amazing, caring, attentive, and just absolutely the best! Thank you for a positive experience on my first surgery. And a shout out to Dr. Tuckman for doing an amazing job fixing my wrist. The dude who gave me my nerve blocker was awesome too!!! I just don’t know his name. Suite 100D has all the best peeps!!
