Sinus-Focused Care for Ventura County, Set Up Just Across the County Line
Southern California Sinus Institute focuses on the medical and surgical care of nasal and sinus conditions from its West Hills location near the Ventura County line. Dr. Cohen’s practice is centered on nasal and sinus disorders rather than the full range of general ENT care, and the West Hills location is designated a national Stryker Balloon Sinus Center of Excellence, where many minimally invasive procedures are done in the office under local anesthesia.
Ventura County patients may seek evaluation for persistent congestion, recurrent sinus infections, facial pressure, suspected structural blockage, or symptoms that continue after prior sinus treatment. Evaluation begins with a consultation and examination and may include nasal endoscopy, imaging, cultures, allergy testing, or other testing when clinically appropriate, to help guide an individualized treatment plan.
Making the Trip From Ventura County to the West Hills Office
There is no Southern California Sinus Institute office inside Ventura County. All care is delivered from the single West Hills location at 7345 Medical Center Drive, Suite 510, near UCLA West Valley Medical Center and just over the county line between Los Angeles County and Ventura County. US-101 is a major regional route for many Ventura County communities, including Thousand Oaks, Newbury Park, Camarillo, Oxnard, and Ventura. Routes from communities such as Simi Valley and Moorpark can differ, so the best route depends on the patient’s starting point and current traffic conditions. The front desk can help you choose an available appointment time, while travel time will vary based on traffic and where you are coming from
That single location keeps the visit simple. For selected patients, balloon sinus dilation and some other procedures may be performed in the office under local anesthesia. Whether evaluation and treatment occur on the same day, whether hospital or surgery-center care is needed, and the expected recovery depend on the diagnosis and procedure. The West Hills location gives Ventura County patients an option for sinus-focused care without traveling into central Los Angeles.
Why Ventura County Patients May Consider Dr. Cohen in West Hills
Ventura County patients comparing sinus-care options may consider the following clinical, diagnostic, and practical features of the West Hills practice.
A sinus-only practice
Dr. Cohen limits his work to nasal and sinus disorders, so sinus care is his whole focus rather than one slice of a general ENT clinic.
Center of Excellence designation
The West Hills location is a national Stryker Balloon Sinus Center of Excellence on the West Coast.
In-office procedures under local anesthesia
Many treatments that once needed an operating room, including balloon sinuplasty, can be performed in the office, which may shorten downtime for suitable patients.
Thousands of procedures behind him
Dr. Cohen has personally performed 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 navigation
The institute uses the Fiagon image-guidance system, which loads a patient’s CT scan to reference the patient’s CT anatomy during selected sinus procedures.
A full workup under one roof
Nasal endoscopy, in-office sinus CT, nasal and sinus cultures, blood allergy testing, and home sleep studies are all available on site.
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 board-certified in Otolaryngology, Head and Neck Surgery and an Assistant Clinical Professor of Surgery at the David Geffen School of Medicine at UCLA.
A location near Ventura County

Potential Goals of Sinus Treatment for Ventura County Patients
Treatment goals depend on the diagnosis, symptoms, and procedure. The sections below describe several goals that may be discussed during evaluation and treatment planning.
Breathing More Easily With an Office-Based Option for Selected Patients
For many patients, the goal is to improve nasal breathing while keeping recovery manageable. In-office balloon sinuplasty widens selected sinus openings using a small balloon. Stand-alone balloon dilation does not remove tissue with the balloon itself, so recovery may be relatively short for appropriate patients, although recovery varies and can be longer when other procedures are performed at the same time. Dr. Cohen performs balloon sinuplasty under local anesthesia at the West Hills office when appropriate.
Reducing Recurrent Sinus Symptoms and Antibiotic Use When Appropriate
For patients with recurrent symptoms or repeated antibiotic use, the evaluation looks for contributing factors such as inflammation, structural narrowing, allergy, infection, or a combination. Treatment is then matched to the findings rather than assuming every flare has the same cause. The goal is to manage the underlying condition and reduce its effect on daily life when possible.
Improved Nasal Airflow After Septoplasty
A deviated septum can contribute to persistent nasal obstruction. Septoplasty straightens the nasal septum and may be paired with turbinate treatment when clinically appropriate. The primary goal is to improve nasal airflow; sleep symptoms can have multiple causes and should be evaluated separately when needed.
A Quieter Day With Less Congestion and Pressure
Post-nasal drip, a constant stuffy feeling, and low-grade sinus headaches wear people down even when they are not severe. Depending on the cause, the answer may be a minimally invasive procedure, treatment for rhinitis such as Clarifix, or medical management. The goal is to reduce symptoms based on the underlying diagnosis. Dry or windy conditions may aggravate nasal irritation or allergy symptoms for some people, but persistent congestion and pressure can have multiple causes.
The Complete List of Sinus and Nasal Services for Ventura County Patients
In-office balloon sinuplasty to open blocked sinus
Submucous turbinate reduction to ease chronic nasal congestion
Septoplasty to straighten a deviated septum when septal deviation contributes to nasal obstruction
In-office polypectomy to remove nasal and sinus polyps
Endoscopic sinus surgery for more advanced sinus disease
Image-guided endoscopic sinus surgery using the Fiagon system for intraoperative image guidance
Revision sinus surgery for symptoms that persist after earlier procedures
Eustachian tube dilation for ear pressure and eustachian tube dysfunction
Clarifix cryoablation for chronic rhinitis and a persistent runny nose
Latera lateral valve repair for nasal valve collapse
Laser-assisted uvuloplasty for snoring
Nasal endoscopy and in-office sinus CT imaging for diagnosis
Blood allergy testing for environmental allergens
Home sleep study for snoring and suspected sleep apnea
Four Categories of Sinus and Nasal Treatment for Ventura County Patients
Care at the West Hills location is grouped into four broad categories, each matched to the underlying problem after a full evaluation. Depending on the diagnosis, a treatment plan may involve one or more of the categories below.
In-Office Balloon Sinuplasty for Selected Patients
The core of the practice is in-office balloon sinuplasty, often paired with submucous turbinate reduction or in-office polypectomy when needed. The practice uses the Fiagon image-guidance system to reference the patient’s CT anatomy during selected procedures. Selected office-based procedures may be performed while the patient is awake under local anesthesia, and some can be completed in a single treatment visit depending on the diagnosis and plan.
Septoplasty and Nasal Valve Repair for a Blocked Airway
For structural blockage, the institute offers septoplasty to straighten a deviated septum along with Vivaer and Latera treatment for nasal valve narrowing and collapse. These options may be considered when structural narrowing, septal deviation, or nasal valve dysfunction contributes to obstruction and conservative treatment alone is not sufficient. When it makes sense, airway work is combined with sinus treatment in one coordinated plan.
Image-Guided Endoscopic Surgery for More Advanced Sinus Disease
When sinus disease is more advanced, Dr. Cohen performs endoscopic sinus surgery and image-guided endoscopic sinus surgery, including revision surgery for patients whose earlier procedures did not fully resolve their symptoms. Image guidance provides CT-based anatomic reference during surgery and may be particularly useful in selected complex or revision cases. These cases are planned individually around each patient’s history and imaging.
Help for a Runny Nose, Snoring, and Ear Pressure
The institute also treats the conditions that often travel with sinus complaints, including chronic rhinitis with Clarifix cryoablation, snoring with laser-assisted uvuloplasty, and eustachian tube dysfunction with in-office dilation. Handling these in one practice means a patient juggling several overlapping issues does not have to bounce between offices.
About Dr. Alen Cohen, the Institute’s Founder and Sinus Surgeon
Care at the West Hills location is led by the institute’s founder, Dr. Alen Cohen, whose credentials and sinus-focused experience are detailed below.
Alen N. Cohen, MD, FACS, FARS, Board-Certified ENT and Sinus Surgeon
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 devoted entirely to nasal and sinus disorders. He earned a Bachelor of Science in Neuroscience from UCLA, graduating summa cum laude and Phi Beta Kappa, then completed his medical degree at the David Geffen School of Medicine at UCLA and a Head and Neck Surgical Residency at UCLA Medical Center. He is board certified by the American Board of Otolaryngology, Head and Neck Surgery, a Fellow of the American College of Surgeons and the American Rhinologic Society, and an Assistant Clinical Professor of Surgery at the David Geffen School of Medicine at UCLA. His focus on minimally invasive, in-office techniques helped make the West Hills location 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. He has been recognized as a Castle Connolly Top Doctor and a Los Angeles Magazine Super Doctor, and he served as Chief of Surgery at West Hills Hospital & Medical Center, now UCLA West Valley Medical Center, from 2013 to 2018.
Ventura County Patients’ First Questions About the West Hills Institute
Where is the Southern California Sinus Institute in relation to Ventura County? The institute is at 7345 Medical Center Drive, Suite 510 in West Hills, just over the county line between Los Angeles County and Ventura County and near US-101. Ventura County patients travel in rather than visiting an office inside the county.
How do patients get there from around Ventura County? The best route depends on where you start. US-101 is a major route for many Ventura County communities, while patients coming from Simi Valley, Moorpark, and other inland areas may use different freeway or local-road connections. Drive time depends on where in the county you start and the time of day, and the front desk can help you choose an available appointment time.
Does the institute focus only on sinus and nasal care? Yes. Dr. Cohen limits his practice to nasal and sinus disorders, from chronic sinusitis and deviated septum to nasal polyps and rhinitis, rather than the full range of general ENT. That subspecialty focus is central to how the practice serves patients seeking focused nasal and sinus care.
Ventura County Cities and Corridors Served From West Hills
Southern California Sinus Institute serves patients from communities across Ventura County, including:
- Thousand Oaks, CA
- Simi Valley
- Moorpark
- Newbury Park
- Westlake Village
- Camarillo
- Oxnard
- Ventura (San Buenaventura)
- Ojai
- Santa Paula
- Fillmore

Getting Sinus Care Done Between Ventura County Commitments
Ventura County keeps its own pace, whether that means a commute down the 101 toward the Valley or the Westside, weekends on the trails around Wildwood Regional Park or in the Los Padres foothills, and errands near the Thousand Oaks and Camarillo corridors. Dry or windy conditions may aggravate nasal irritation or allergy symptoms for some people, but persistent sinus symptoms can have multiple causes. For appropriate patients, some office-based procedures may involve a relatively short recovery, while the timing and downtime depend on the treatment performed. The institute keeps weekday hours Monday through Thursday and wraps earlier on Friday afternoons, so a consultation or procedure can slot into a working week instead of taking it over.

What Patients Say About Their Experience With Dr. Cohen
These testimonials describe individual patient experiences and are not necessarily from Ventura County patients. Treatment and recovery experiences vary.
“Dr Cohen is very kind. My surgery went very well. His office staff are equally as good. They are all very pleasant, respond quickly and efficiently. The procedure itself was a fairly easy recovery. He gave me pain meds, but honestly I really did not need them. The after care he prescribed was great. I’ve had sinus surgery previously and this time around was a completely different experience. I can smell again! I would most definitely recommend this office to others who have sinus issues.”
“Dr. Cohen is both thoughtful and caring in his approach. After suffering with sinus issues for eighteen years I was referred to Dr. Cohen by an urgent care doctor. I under went sinus surgery and it was the best decision i ever made for my health and well being. Five years post-op I am happier and healthier. I would recommend Dr. Cohen above any other physician I’ve seen. He cares about his patients and is a leader in his field.”
“It’s always a pleasant and informative experience at Dr. Cohen’s office. The staff is friendly and Dr. Cohen takes his time and explains everything. I never feel the appointment is rushed. He always answers my questions. Dr. Cohen is also careful about things like weaning me off the medications or treatment. He wants to reach certain milestones before doing any of that. Also, the sinus surgery went well too. I didn’t experience a lot of bleeding and did not have any complications. Thanks Dr. Cohen and staff!”
Sinus and Nasal Treatment FAQs for Ventura County Patients
How painful is balloon sinuplasty?
Balloon sinuplasty is commonly performed with local anesthesia in the office for appropriate patients. Sensations vary and may include pressure, fullness, or discomfort during or after treatment. Dr. Cohen reviews what to expect before you begin.
How long does it take to fully heal from a balloon sinuplasty?
Recovery after balloon sinuplasty varies by patient and by whether other procedures are performed at the same time. Some patients may return to normal activities relatively quickly after stand-alone balloon dilation, while congestion, pressure, or swelling can take longer to settle. Follow the recovery guidance your treating provider gives you for your specific procedure.
How to tell if you need a balloon sinuplasty?
Balloon sinuplasty is generally considered when chronic or recurring sinusitis has not responded well to medication and imaging shows blocked or narrowed sinus openings. A consultation with nasal endoscopy and a CT scan helps confirm whether the blockage is something the balloon can address. Not every sinus problem is suited to it, which is why the evaluation matters.
Does a deviated septum get worse as we age?
A deviated septum does not necessarily become progressively worse with age, but age-related changes in nasal cartilage and support can affect airflow and make nasal obstruction more noticeable. The more useful question is usually whether the deviation is causing enough congestion, sleep disruption, or recurring problems to justify repair. Dr. Cohen weighs symptoms and anatomy together rather than age alone.
Is septoplasty a risky surgery?
Septoplasty is commonly performed, but like any surgery it carries potential risks. These can include bleeding, infection, septal perforation, persistent nasal obstruction, changes in sensation, or other complications. Dr. Cohen reviews the potential benefits and risks based on your anatomy, symptoms, and health history before recommending surgery.
How long does the nose take to heal after septoplasty?
Many patients feel noticeably better within one to two weeks, while deeper internal healing continues over several weeks as swelling settles. Following aftercare instructions and keeping follow-up visits can support healing and allow your provider to monitor your recovery. Timelines vary by patient and case.
Will my nose look different after septoplasty?
Septoplasty works on the inside of the nose to straighten the septum, so it typically does not change how the nose looks from the outside. If a patient wants a change in external shape as well, that is a separate cosmetic discussion. Dr. Cohen explains which applies to your situation.
Are you awake during endoscopic sinus surgery?
It depends on the extent of the procedure. Many in-office treatments, including balloon sinuplasty, are done while you are awake under local anesthesia, whereas more advanced endoscopic sinus surgery is often performed under general anesthesia. Dr. Cohen explains exactly how your procedure will be handled during the consultation.
How long does an endoscopic sinus surgery take?
The length of endoscopic sinus surgery varies with the extent of disease, the sinuses being treated, and whether other procedures are performed at the same time. Dr. Cohen can give you a more specific estimate after reviewing your examination and imaging.
How long does it take to fully recover from endoscopic sinus surgery?
Recovery after endoscopic sinus surgery varies with the extent of surgery and the patient’s individual healing. Activity usually resumes gradually, while internal healing can continue for weeks to months. Saline care and follow-up are commonly part of postoperative management, and Dr. Cohen will give you instructions based on the procedure performed.
Do Ventura County's dry winds and pollen seasons make chronic sinusitis worse?
Dry, windy conditions and airborne allergens can aggravate nasal or allergy symptoms for some people, but they do not explain every case of chronic sinusitis. If symptoms seem seasonal or exposure-related, allergy evaluation may help determine whether environmental triggers are contributing.
Can Dr. Cohen help Ventura County patients whose earlier sinus surgery did not fully work?
Yes. Revision sinus surgery is part of the practice, and Dr. Cohen evaluates why the previous procedure did not resolve symptoms before recommending a next step. Bringing prior operative notes and any recent CT scans to the consultation helps him plan an appropriate next step.
Does the institute offer Clarifix or Vivaer for Ventura County patients with constant congestion or a runny nose?
Yes. Clarifix cryoablation targets chronic rhinitis and a persistent runny nose, while Vivaer treats narrowing at the nasal valve that can leave the nose feeling blocked. Dr. Cohen decides which, if either, fits after examining the nasal airway.
Can balloon sinuplasty be completed in a single in-office visit for Ventura County patients?
For appropriate candidates, the balloon dilation procedure itself can often be completed during an office visit under local anesthesia. The diagnostic evaluation may occur separately, and whether additional procedures or a hospital or surgery-center setting are needed depends on the individual treatment plan.
Which sinus and nasal conditions does Dr. Cohen evaluate for Ventura County patients?
The practice evaluates conditions including chronic sinusitis, recurrent sinus infections, nasal congestion, deviated septum, nasal polyps, rhinitis, and other nasal or sinus concerns. Because the practice focuses only on nasal and sinus disorders, these are the conditions Dr. Cohen treats every day.
Sinus Care for Ventura County Patients in West Hills
If sinus pressure, congestion, or a nose that never fully clears has become part of your routine, Dr. Cohen will listen first and learn what you have already tried before suggesting anything. He walks through the choices in plain language, from in-office balloon sinuplasty to septoplasty and endoscopic sinus surgery, and shapes the plan around how clearly you breathe and how you feel across a normal Ventura County week. Whenever you are ready to stop letting sinus trouble set the pace, get in touch and the team will take it from there.
