Nasal Obstruction? Septal Surgery

Many adults have a deviated septum. When the deviation is severe enough to obstruct nasal passages, it can cause persistent nasal congestion and difficulty with exercise tolerance. It may also contribute to sleep disorders, such as snoring and sleep apnea. See what one of the top ENT doctors Los Angeles has to offer and call today!

Septal Surgery >>

Breathe Freely Turbinate Reduction

This procedure is for patients who have chronic swelling of the nasal turbinates (narrow shelves of bone protruding into the breathing passages), when other medical treatments have failed.

Turbinate Reduction >>

Non-Surgical RestorationBalloon Sinuplasty

In this procedure, the doctor uses a small, inflatable, sinus balloon catheter to gently restructure and widen the walls of the sinus passageway, restoring normal sinus drainage and function while preserving the anatomy and integrity of the sinuses.

Deviated Septum

Under ideal circumstances, the nasal septum is perfectly straight and located precisely in the middle of the nose, which makes both sides of the nasal cavity equal in size. Unfortunately, this ideal situation is seldom the reality. More than 80% of the population has some degree of deviation or crookedness of the nasal septum. The septum is usually straight at birth and remains straight throughout childhood. However, as a person ages, the septum has a tendency to bend to one side or the other. Sometimes the septum is bent as a result of birth trauma. Although trauma may be a factor in producing septal deviation during childhood or adult life, in many cases, there is no history of injury to account for the irregularity. Learn how Dr. Zadeh, one of the best sinus doctors Los Angeles has to offer, corrects and alleviates the symptoms of a deviated septum.

Turbinate Hypertrophy

A chronically stuffy nose often results from enlargement (hypertrophy) of the inferior nasal turbinates. Turbinates are long, narrow shelves of bone that protrude into the breathing passage in the nose. Inferior turbinates, the largest of the 3 pairs of turbinates in the nose, are often the cause of breathing problems when they become enlarged. Turbinates perform important functions in the body. They humidify, filter, and warm the air we breathe. Dr. Zadeh preserves the critical function of turbinates when treating turbinate hypertrophy. His approach to treating this makes hime likely the top nasal surgeon Los Angeles can offer.

Nasal Allergies

An allergy is an overreaction of the body’s immune system to a typically harmless substance. A person without allergies will have no reaction to such substance, but when a person who is allergic to the substance encounters it, the body reacts by releasing chemicals which cause allergy symptoms. Nasal allergy symptoms can be triggered by substances such as pollen, mold, dust mite, animal dander and environmental irritants such as smog and climate factors. Nasal Allergies occur in up to 30% of adults and up to 40% of children. In the US, the prevalence of allergies has been increasing since the early 1980s. Experts estimate that allergies affect as many as 40 to 50 million Americans. Pollen allergies are one of the most common chronic conditions in the US.

Sinusitis is an inflammation of the nasal sinuses. Under normal circumstances, the sinuses produce a small amount of mucus. However, when inflammation sets in, the mucosal lining substantially increases mucus production. Inflammation is usually caused by bacterial, fungal, viral or allergic processes. The inflammation of the nasal sinuses leads to swelling of the sinus mucosa, resulting in blockage of the sinus drainage. Thus, the pus cannot escape into the nose and builds up pressure inside the sinus cavities, causing increased inflammation. This creates a vicious cycle of increasing inflammation and obstruction of the drainage pathways.

Nasal Polyps

Nasal polyps are soft, non-cancerous growths that develop on the lining of the nose or sinuses. They are the end product of chronic inflammation that may result from a viral or bacterial infection, allergies, or an immune system response to fungus. Chronic inflammation causes the blood vessels in the lining of the nose and sinuses to become more permeable, allowing water to accumulate in the cells. Over time, as gravity pulls on these waterlogged tissues, they develop into polyps. Polyps are generally soft and pearl colored, with a consistency like jelly. Polyps may be single or several, clustered together like grapes on a stem.

Sinus CT Imaging

One of the best ways to diagnose sinus problems is with a CT (computed tomography) scan, also known as a CAT scan, a noninvasive, painless medical test that helps physicians diagnose and treat various medical conditions. CT scanners create 3 dimensional x-ray images of the sinus anatomy and thus provide physicians with valuable information for an accurate diagnosis.

Nasal Endoscopy

Diagnostic nasal endoscopy provides a safe and quick evaluation of the nasal passages using a nasal endoscope, a fiber-optic instrument used for examining the nasal cavity. The endoscope is slender, only 2.7-4.0 mm in diameter, and is passed easily through the nostril to allow a detailed examination of the nasal cavity and the sinuses. Dr. Zadeh may look directly through the endoscope or alternatively, a medical video camera can be attached to the endoscope, and the images may be viewed on a special video monitor. The patient may choose to view the images from his or her own examination.

Sinus Cultures

Nasal and sinus cultures are used to identify the organism causing the infection. Cultures are simple, quick and safe. Cultures are frequently used when infections treated with the appropriate antibiotics have not completely resolved. Nasal and sinus cultures are becoming more important with the emergence of bacteria resistant to common antibiotics. Patients at the Los Angeles Sinus Institute have access to our in-house microbiology laboratory overseen by our experienced microbiologist. The cultures obtained allow Dr. Zadeh to determine the source of the patient’s nasal and sinus infection.

Allergy Testing

This helps us determine which specific allergens are causing sinus symptoms. We use skin testing - the oldest and most reliable form of allergy testing. The process is not painful, and it takes approximately one hour. Once the allergens causing the allergic reaction have been identified, we can administer immunotherapy in the form of allergy shots to help train the immune system over time to better tolerate the allergens that have been triggering the uncomfortable symptoms.
