Our Procedures


C/V ENT Surgical Group is one of the premiere ENT surgical providers in the country, utilizing minimally invasive techniques in complex nose, sinus, thyroid and parathyroid surgical procedures. But what truly sets us apart from all the rest is providing the most outstanding care and compassion to each patient. Below are some of the surgeries our physicians perform:

Head & Neck Surgery

Head and neck surgery is extremely complicated and performed by only the most skilled and knowledgeable surgeons. Procedures include removal of various head and neck and facial tumors, oral cavity and tongue surgery as well as minimally invasive parotid and salivary gland tumor surgery.

Thyroid & Parathyroid Surgery

Dr. Cohen is Director of the Minimally Invasive Thyroid and Parathyroid Surgery Program at West Hills Hospital and Medical Center, which is the only center of its kind in the San Fernando Valley and Thousand Oaks regions.  It is one of 3 recognized centers in the Los Angeles area.  The center serves patients that come from all parts of Southern California and Dr. Cohen has performed over 500 minimally invasive thyroid/parathyroid procedures over the last 5 years. With this procedure the incisions are typically between 1 and 1.5 inches in a natural skin crease using either an endoscope or eye-loop magnification. These cutting-edge techniques ensure the best minimal recovery possible as all parathyroid and most thyroid patients go home within 4 hours of surgery to recover in the comfort of their own home. The doctors also specialize in parathyroidectomy, hemithyroidectomy,  total thyroidectomy, neck exploration, thyroid cancer and thyroid goiter surgeries as well as central and lateral neck compartment dissections in Los Angeles.

Nasal & Sinus Surgery

Some nasal and sinus problems require surgical attention.  Whether the problems arise from chronic allergies or anatomic problems such as a deviated septum, nasal fractures, large turbinates or nasal polyps our doctors specialize in performing functional endoscopic sinus surgery, minimally invasive image-guided endoscopic sinus surgery, balloon sinuplasty, septoplasty, submucous resection of inferior turbinates and nasal polypectomy in Los Angeles. Our method of treating deviated septums through a simple and effective surgery is acclaimed because patients experience minimal amounts of discomfort and downtime. C/V ENT Surgical Group also caters to patients looking to get a rhinoplasty, which in everyday jargon is called a nose job or nose reshaping.   Dr. Cohen is also Founder and Director of Southern California Sinus Institute, a premier center for advanced nose and sinus surgery.

Snoring & Sleep Apnea Treatment

Snoring and sleep apnea often stem from nasal and throat problems. The board-certified physicians at C/V ENT Surgical Group treat patients for these issues quite often. We always try to address the problem with the least invasive procedure before proceeding with more aggressive procedures.  Our treatment options include pillar implants, laser assisted uvulopalatoplasty, coblation turbinates, adenotonsillectomy, uvulopalatopharyngoplasty, tongue base reduction, genioglossus advancement, septoplasty and submucous resection of inferior turbinates.
