San Fernando Valley Sinus Treatment With In-Office Balloon Sinuplasty and Endoscopic Surgery, Minutes Off the 101
For San Fernando Valley residents who have spent months cycling through antibiotics, nasal sprays, and allergy medication without lasting relief, a focused sinus and nasal center can change the picture. Southern California Sinus Institute is located at 7345 Medical Center Drive, Suite 510, near UCLA West Valley Medical Center in the western San Fernando Valley, just off US-10 for patients across the region. Care is led by Alen N. Cohen, MD, FACS, FARS, a board-certified ENT and head and neck surgeon who founded the institute in 2009 and concentrates entirely on nasal and sinus disorders, from chronic sinusitis and deviated septum to nasal polyps and recurrent sinus infections.

A Dedicated Sinus and Nasal Center Serving the San Fernando Valley From West Hills
Patients across the San Fernando Valley often face a frustrating choice when a sinus problem turns chronic. General ENT offices may treat the sinuses as one small part of a much broader practice, while the surgeons with deep nasal and sinus experience tend to be clustered over the hill in Los Angeles or Beverly Hills. Southern California Sinus Institute was built to remove that tradeoff by keeping subspecialty sinus care inside the Valley itself. Dr. Cohen dedicates his entire practice to the medical and surgical management of nasal and sinus conditions, and the West Hills institute is designated as a national Stryker/Entellus Sinus Center of Excellence. Dr. Cohen also performs many minimally invasive sinus procedures in the office under local anesthesia.
The patients who travel to West Hills reflect the full range of the Valley. Some are working professionals commuting along the 101 who are tired of losing days to sinus headaches and facial pressure. Others are longtime allergy sufferers from Encino, Tarzana, or Sherman Oaks whose congestion never fully clears, and a smaller group arrives after previous sinus surgery elsewhere that did not hold. Each begins the same way, with a thorough consultation, nasal endoscopy, and imaging when needed, so the treatment plan fits the specific cause rather than a generic protocol.
Getting to the West Hills Institute From Across the Valley Floor
The institute does not run satellite offices scattered across the Valley. All care is delivered from the single West Hills location at 7345 Medical Center Dr, on the medical campus beside West Hills Hospital and Medical Center. For patients coming from the central and eastern Valley, the US-101 Ventura Freeway makes the trip straightforward, with most drives from Woodland Hills, Tarzana, or Encino landing in the fifteen to twenty-five minute range depending on traffic, and Sherman Oaks or Studio City reachable in a reasonable window against the flow of commuter traffic.
That single location keeps things simple for Valley families. Because most balloon sinuplasty and in-office procedures are done under local anesthesia in a single visit, a patient can often handle diagnosis and treatment without arranging a hospital stay or a long recovery, then fold the appointment into an ordinary day of errands along Ventura Boulevard or a stop near Topanga Village. The West Hills setting also spares Valley patients the drive over the Sepulveda Pass into Los Angeles or Beverly Hills for the same level of subspecialty sinus surgery.
What Draws San Fernando Valley Patients to Dr. Cohen for Sinus Care
The Valley has no shortage of ENT and allergy options, so patients who choose Dr. Cohen and the West Hills institute usually point to the same handful of reasons.
Sinus-only focus:
Dr. Cohen limits his practice to nasal and sinus disorders rather than splitting attention across the full range of general ENT complaints
Center of Excellence designation:
the West Hills institute is a national Stryker Balloon Sinus Center of Excellence located on the West Coast
In-office procedures under local anesthesia:
many treatments that once required an operating room can now be performed in the office, which may reduce downtime for appropriate patients
Thousands of procedures performed:
Dr. Cohen has personally completed more than 5,000 in-office sinus procedures since founding the institute in 2009
A surgeon other surgeons learn from:
as a national instructor, Dr. Cohen trains ENT physicians from around the country on in-office balloon sinus dilation and hybrid techniques
Image-guided precision:
the institute uses the Fiagon image-guidance system, which loads a patient’s CT scan to target and open the sinuses with precision
Full diagnostic workup on site:
nasal endoscopy, in-office sinus CT, nasal and sinus cultures, blood allergy testing, and home sleep studies are available under one roof
Revision and complex cases welcome:
patients whose earlier sinus surgery did not fully resolve their symptoms can be evaluated for revision options
University-level credentials:
Dr. Cohen is a board-certified ENT and head and neck surgeon and an Assistant Clinical Professor of Surgery at the David Geffen School of Medicine at UCLA
A location built for the Valley:
the West Hills campus sits just off the 101, sparing patients the drive over the hill into Los Angeles for subspecialty sinus care
The Relief San Fernando Valley Patients Come to the Institute to Find
Every treatment plan at the West Hills institute is aimed at a concrete result, not just a procedure. Four outcomes come up again and again for Valley patients.
Easier Breathing Without a Long Surgical Recovery
For many Valley patients, the goal is simply to breathe through the nose again without a week of downtime. In-office balloon sinuplasty gently widens blocked sinus passages using a small balloon rather than cutting or removing tissue, which is why most patients return to normal activity quickly. Dr. Cohen performs the procedure under local anesthesia in the West Hills office, so the path from consultation to relief can be short.
Long-Term Management of Chronic Sinusitis and Repeat Infections
Patients who have spent years on repeated antibiotic courses are usually looking for something that finally holds. By identifying whether the underlying driver is inflammation, a structural blockage, allergy, or a combination, Dr. Cohen can target the actual cause rather than treating each flare in isolation. The goal is fewer infections, less facial pressure, and fewer disruptions to work and daily life.
A Clear Nasal Airway After Deviated Septum Repair
A deviated septum can leave one side of the nose persistently blocked and disrupt sleep for years. Septoplasty straightens the wall between the nasal passages and may be combined with turbinate reduction when appropriate. The goal is steadier nasal breathing and improved sleep quality.
Fewer Sinus Headaches and Less Daily Congestion
Sinus headaches, post-nasal drip, and a constant stuffy feeling wear people down even when they are not severe. Whether the answer is a minimally invasive procedure, treatment for rhinitis such as Clarifix, or medical management, the objective is the same: a noticeable drop in the everyday congestion and pressure that follow Valley allergy seasons and dry Santa Ana winds.
How Sinus and Nasal Care Is Organized at the West Hills Institute
Care at the West Hills institute is grouped into four broad categories, each matched to the underlying problem after a full evaluation.
In-Office Balloon Sinuplasty and Minimally Invasive Procedures
The core of the practice is in-office balloon sinuplasty, often paired with submucous turbinate reduction or in-office polypectomy when needed. These procedures are performed under local anesthesia using the Fiagon image-guidance system, which lets Dr. Cohen opens the sinuses precisely while the patient stays comfortable and awake. Many in-office procedures can be completed during a single treatment visit, depending on the patient’s diagnosis and treatment plan.
Deviated Septum Repair and Nasal Airway Treatment
For structural blockage, the institute offers septoplasty to straighten a deviated septum along with Vivaer treatment for nasal valve narrowing. These options address the physical causes of a blocked nose rather than masking them with medication. When appropriate, airway work is combined with sinus treatment in a coordinated plan.
Endoscopic and Image-Guided Sinus Surgery
When sinus disease is more advanced, Dr. Cohen performs endoscopic sinus surgery and image-guided endoscopic sinus surgery, including revision sinus surgery for patients whose previous procedures did not fully resolve their symptoms. Image guidance maps the CT scan onto the surgical field for accuracy in difficult anatomy. These cases are planned individually around each patient’s history and imaging.
Rhinitis, Snoring, and Eustachian Tube Care
The institute also treats conditions that often accompany sinus complaints, including chronic rhinitis with Clarifix cryoablation, snoring with laser-assisted uvuloplasty, and eustachian tube dysfunction with in-office dilation. Grouping these treatments in one practice means a patient dealing with several overlapping issues does not have to see several different offices.

The Sinus Surgeon Behind Every Treatment Plan at the Institute
Every consultation, procedure, and follow-up at the West Hills institute is handled by its founder.
Alen N. Cohen, MD, FACS, FARS, Founder and Director
Dr. Alen Cohen is a board-certified ENT and head and neck surgeon who founded Southern California Sinus Institute in 2009 and has built it into a practice focused entirely on nasal and sinus disorders. Dr. Cohen earned a Bachelor of Science in Neuroscience from UCLA, graduating summa cum laude and Phi Beta Kappa, before earning his medical degree from the David Geffen School of Medicine at UCLA. He is a Fellow of the American College of Surgeons and the American Rhinologic Society, board certified by the American Board of Otolaryngology, Head and Neck Surgery, and serves as an Assistant Clinical Professor of Surgery at the David Geffen School of Medicine at UCLA. His focus on minimally invasive, in-office techniques has made the West Hills institute a Stryker Balloon Sinus Center of Excellence, and he has personally performed more than 5,000 in-office sinus procedures while training ENT physicians from across the country on the same methods. Recognized as a Castle Connolly Top Doctor and a Los Angeles Magazine Super Doctor, he also served as Chief of Surgery at West Hills Hospital and Medical Center from 2013 to 2018.
What Valley Patients Usually Want to Know Before Booking a Sinus Consultation
How far is the West Hills office from central Valley neighborhoods like Encino or Sherman Oaks?
The institute is at 7345 Medical Center Dr in West Hills, just off the US-101. Most patients from Encino, Tarzana, or Sherman Oaks reach it in roughly fifteen to twenty-five minutes depending on the time of day, and the front desk can help schedule around typical Valley traffic.
Are the sinus procedures done in the office, or do I need to go to a hospital?
Most procedures, including balloon sinuplasty, are performed right in the West Hills office under local anesthesia, so a hospital stay is usually not required. More complex endoscopic surgeries are planned individually, and Dr. Cohen reviews exactly where and how your treatment will happen during the consultation.
Is parking easy to find at the Medical Center Dr location?
Yes. The institute sits on the West Hills Hospital medical campus, which has on-site parking, so you will not need to hunt for street parking before your appointment. The office can send entry and suite directions when you confirm your visit.

Where Sinus Care Fits Into a Busy Week in the Valley
Life in the San Fernando Valley moves at the pace of the 101, with early commutes toward the Westside or downtown, kids shuttled to schools and practices, and weekends spent along Ventura Boulevard, at Topanga Village, or on the canyon trails that ring the Valley floor. Sinus trouble has a way of dragging on that pace, especially through allergy season and the dry stretches when Santa Ana winds push dust and pollen across the basin. Because so much of the care here happens in a single in-office visit under local anesthesia, a Valley patient can address a long-standing sinus problem without clearing a week off the calendar. The institute keeps weekday hours through the week and closes earlier on Friday afternoons, which lets patients slot a consultation or procedure into a normal working stretch rather than rebuilding their whole schedule around it.
In Their Own Words: Recent Patients on Working With Dr. Cohen
“Dr. Cohen was very patient, kind, honest and listened to our concerns. He was very personable with my brother and myself. His recommendations considering my brother’s health and age were very honest and put my concerns at ease.”
“Dr. Cohen is the best hands down. Not only is he super personable and caring, he’s an amazing doctor. I went to see him for a post nasal drip issue I’ve been dealing with for over a decade. Very straight forward on what the diagnosis was, confirmed with CT, in office procedure (which I was VERY nervous about) and I am so happy. I am no longer dealing with postnasal drip and the procedure was PAINLESS.”
“So far, I am very pleased with the treatment I have received. Dr. Cohen explained the procedure clearly and patiently answered all questions. I had a good idea of what to expect during my sinuplasty. The staff is also very responsive, polite, and helpful. I definitely recommend Dr. Cohen based on my experience thus far.”

Frequently Asked Questions About San Fernando Valley Sinus Treatment
Why do people get balloon sinuplasty?
Most patients choose balloon sinuplasty because they are tired of chronic sinus pressure, congestion, and repeat infections that medication alone has not fixed. The procedure gently widens blocked sinus passages so they can drain normally, which may provide longer-term symptom relief for appropriately selected patients. Because it does not involve cutting or removing tissue, recovery is usually quick.
How risky is balloon sinuplasty?
Balloon sinuplasty is a minimally invasive procedure, but, like any medical procedure, it carries potential risks. Dr. Cohen reviews each patient’s anatomy, symptoms, imaging, and health history before recommending it. Most patients tolerate the procedure comfortably and return to normal activity soon after.
How do you qualify for balloon sinuplasty?
Good candidates typically have chronic or recurring sinusitis that has not responded well to medications, along with imaging that shows blocked or narrowed sinus openings. A consultation with nasal endoscopy and a CT scan helps confirm whether the blockage is something balloon sinuplasty can address. Not every sinus problem is suited to the balloon, which is why the evaluation matters.
What is the best age to correct a deviated septum?
Septoplasty is generally recommended once the nasal structure has finished growing, usually in the late teens or older, and it can be performed safely well into adulthood. The more useful question is often whether the deviation is causing enough blockage, sleep disruption, or recurring problems to justify repair. Dr. Cohen evaluates symptoms and anatomy together rather than going by age alone.
What happens if you never fix a deviated septum?
A mild deviated septum will not necessarily harm you, and many people live comfortably without treatment. When it is significant, though, it can lead to ongoing nasal blockage, disrupted sleep, mouth breathing, and more frequent sinus infections over time. Repair becomes worth considering when those effects start interfering with daily life or sleep.
Is endoscopic sinus surgery a major surgery?
Endoscopic sinus surgery is performed through the nostrils without external incisions, so it is far less invasive than older open approaches. It is still a real surgical procedure that requires proper planning and recovery, but most patients go home the same day. Dr. Cohen tailors the extent of surgery to how advanced the sinus disease actually is.
How long does it take to fully recover from endoscopic sinus surgery?
Many patients feel noticeably better within one to two weeks, though full internal healing can take several weeks as swelling settles and the sinuses fully open. Following the aftercare instructions, including saline rinses and follow-up visits, has a large effect on how smoothly recovery goes. Dr. Cohen monitors healing at each follow-up to keep it on track.
Can sinus problems come back after sinus surgery?
Surgery opens and clears the sinuses, but it does not switch off underlying tendencies like allergies or inflammation, so symptoms can sometimes return over time. Ongoing management of allergies and irritants, along with routine follow-up, helps keep results durable. When symptoms do recur after a prior surgery, revision treatment may be considered when symptoms return or persist after earlier surgery.
What are the signs that you need sinus surgery?
Surgery is usually considered when chronic sinus symptoms persist despite a fair trial of medications, when infections keep returning, or when imaging shows a structural blockage or polyps. Warning signs include lingering facial pressure, nasal blockage, a reduced sense of smell, and repeated courses of antibiotics. A full evaluation determines whether surgery or a less invasive option is the right next step.
What is the most common sinus surgery?
Endoscopic sinus surgery is the most common surgical approach for chronic sinusitis. Balloon sinus dilation may be appropriate for selected patients with blocked sinus pathways and can sometimes be performed alone or alongside other procedures. The right option depends on the diagnosis, imaging, symptoms, and extent of the disease.
Do the Valley's allergy seasons and Santa Ana winds make sinus problems worse?
They often can. Dust, pollen, and dry air carried by Santa Ana winds are common triggers that inflame the nasal and sinus lining, which is why many Valley patients notice flare-ups during those stretches. Identifying whether allergies are driving your symptoms, sometimes with in-office allergy testing, helps shape a plan that holds up through the seasons.
Is specialized sinus surgery available within the San Fernando Valley itself?
Yes. The institute was built so San Fernando Valley patients can have subspecialty sinus and nasal surgery close to home rather than traveling out of the area. Procedures from balloon sinuplasty to endoscopic and image-guided sinus surgery are all performed here, keeping specialized care inside the Valley.
How soon can San Fernando Valley patients be seen for a sinus evaluation?
The institute works to see new patients promptly, and the front desk can often find an appointment that fits around a Valley work schedule. Bringing any recent CT scans or records to the first visit can help move things along. Reaching out by phone is the fastest way to find the earliest available time.
What sinus and nasal conditions do San Fernando Valley patients most often come in for?
Many San Fernando Valley patients come in for chronic sinusitis, recurring sinus infections, nasal congestion, and a deviated septum, along with sinus headaches, nasal polyps, and allergy-driven symptoms. Because the practice focuses only on nasal and sinus disorders, these everyday Valley complaints are exactly what Dr. Cohen treats day in and day out.
Can San Fernando Valley patients with busy work schedules still fit in sinus treatment?
In most cases, yes. Because balloon sinuplasty and many procedures are done in the office under local anesthesia, San Fernando Valley patients can often be treated and return to their normal routine quickly rather than planning around a long recovery. That short downtime is one reason working Valley patients choose an in-office approach.
Does the institute serve patients from across the entire San Fernando Valley?
Yes. Patients travel in from communities throughout the San Fernando Valley for sinus and nasal care, and the practice is set up to serve the whole Valley rather than a single pocket of it. Reaching out by phone is the easiest way to confirm scheduling from your part of the Valley.
Sinus and Nasal Care the San Fernando Valley Can Reach Without Going Over the Hill
If you have been quietly managing sinus pressure, congestion, or a nose that never quite clears, Dr. Cohen will take the time to understand exactly what you are dealing with and what has already been tried. He explains the options in plain terms, from in-office balloon sinuplasty to septoplasty or endoscopic surgery, and builds a plan around both how well you breathe and how you feel through a normal Valley week. When you are ready to stop working around the problem, reach out and start the conversation.
