ENT AND SINUS CENTER P C

What ENT AND SINUS CENTER P C does

ENT & Sinus Center P.C. is a single-location otolaryngology (ear, nose, and throat) medical practice headquartered at 8241 Rochester Ave., Suite 130, Rancho Cucamonga, California, serving the Inland Empire region of Southern California. The practice delivers comprehensive ENT, sinus, and allergy care across adult and pediatric patients, with core clinical services spanning chronic sinusitis treatment (including in-office balloon sinuplasty), comprehensive allergy testing and sublingual immunotherapy (allergy drops/shots), general ENT procedures (septoplasty, nasal polyp treatment), and facial plastic and reconstructive surgery. Diagnostic capability is consolidated on-site through in-office CT sinus imaging, nasal endoscopy, and advanced allergy testing, enabling same-visit diagnosis and treatment planning.

The clinical team consists of two board-certified otolaryngologists — Dr. Henry H. Nguyen (founder, in private practice since 1999, with thousands of in-office balloon sinuplasty procedures since 2010) and Dr. Deborshi Roy (dual board-certified in Otolaryngology and Facial Plastic & Reconstructive Surgery) — supported by three physician assistants and an operations manager. The practice maintains hospital affiliations with San Antonio Regional Medical Center, Community Hospital of San Bernardino, and St. Bernardine's Medical Center for surgical cases requiring an operating room. Technology infrastructure is limited to standard clinical practice tools and the AdvancedMD online scheduling platform; no AI, telehealth, or proprietary software products were identified.

Revenue is generated through insurance-billed professional services across office visits, in-office diagnostic procedures (CT, endoscopy, allergy testing), interventional treatments (balloon sinuplasty, septoplasty), and ongoing allergy immunotherapy. Pricing is not publicly disclosed; patients are directed to contact the billing office or their insurer for coverage details. Patient acquisition relies on a combination of local SEO, content marketing via an educational blog, online self-serve scheduling, primary-care-physician referrals, and walk-in/phone inquiries. The practice operates Monday–Friday, 8am–5pm, and is physician-owned as a California professional corporation with no disclosed external investment or parent-company affiliation.

Products and services

• Balloon Sinuplasty Minimally invasive in-office procedure that uses a small balloon to open blocked sinus passages, providing long-term relief for chronic sinusitis without incisions, implants, or visible scarring. Performed under local anesthesia in the office in about an hour, with quick recovery time. Dr. Nguyen has performed thousands of these procedures since 2010.
• Allergy Testing Comprehensive allergy testing including skin prick testing, blood testing, and intradermal skin testing to identify specific environmental allergens (Santa Ana dust, local grasses, mold, regional pollen) affecting patients.
• Allergy Drops (Sublingual Immunotherapy) Sublingual immunotherapy treatment involving drops placed under the tongue to retrain the immune system to tolerate allergens over time, providing a painless alternative to allergy shots. Most patients experience significant improvement within the first month of treatment.
• Septoplasty Surgical procedure to correct a deviated septum by realigning the nasal septum to its anatomically correct position, improving airflow and breathing for patients with structural nasal obstructions.
• Nasal Polyp Treatment Treatment for noncancerous growths on the nasal passages or sinuses, including corticosteroid medications and surgical options such as endoscopic sinus surgery (FESS).
• Sinus Infection Treatment Comprehensive treatment for sinusitis including decongestants, mucolytics, nasal/systemic steroids, irrigation, and balloon dilation procedures to address sinus infections.
• Allergy Treatment Personalized allergy treatment plans including allergy medications, medical procedures, and immunotherapy (allergy shots or drops) tailored to individual patient needs.
• Sinusitis Treatment Treatment for sinus inflammation including medication options, balloon sinuplasty, and functional endoscopic sinus surgery (FESS) for acute, chronic, and recurrent sinusitis.
• General ENT Services General ear, nose, and throat care covering conditions such as voice disorders, sleep apnea, hearing loss, nasal congestion, and related ENT issues for both adult and pediatric patients.
• In-Office CT Scanning State-of-the-art in-office CT sinus imaging for precise three-dimensional mapping of sinus anatomy to identify blockages, extent of disease, and structural contributors such as deviated septum or enlarged turbinates.
• Facial Plastic and Reconstructive Surgery Facial plastic and reconstructive surgery services provided by Dr. Deborshi Roy, including septoplasty and other nasal procedures for adult and pediatric patients.
• Sinus Assessment Quiz Online self-assessment quiz to help patients evaluate their sinus symptoms and determine if they may benefit from specialist evaluation at the practice.
