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

The septum is the inner structure of the nose that separates the two nasal cavities. It is composed of bone and cartilage and covered by a layer of mucus membrane. It extends deep within the nose structure, as far back as the eyes. When this structure is not straight as nature intended, it can impact free breathing, with one nostril less effective than the other. This is a deviated septum – and it can be surgically corrected to restore free breathing and a better quality of life.

It is estimated that about eighty percent of people have some degree of deviation, but not everyone suffers unpleasant symptoms. Whether the damage occurred at birth, playing sports, due to an injury or impact, or as a result of aging, restoring the septum can help with issues such as difficulty breathing, nosebleeds, sinus infections, snoring, or congestion.

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 when the body reacts to an environmental substance. An allergy is an overreaction of the body’s immune system. If your immune system reacts to pet hair, dust, pollen, or other substances, it is an unpleasant experience. A person can be allergic to a wide range of substances, and each person is different in what will trigger an allergic reaction. Allergy symptoms include watery eyes, runny nose, skin conditions, hives, and some other uncomfortable conditions.

An allergic reaction occurs when an allergen enters the body system, triggering a response at the cellular level. In simple terms, what occurs is that antibodies (blood proteins that are produced to protect the body) trigger a chemical response, releasing “histamines.” These histamines have a duty to remove allergens, but can overreact, leading to allergy symptoms.

Sinusitis is the term for a sinus infection or an inflammation of the sinuses, the air passages within the nose that process the air we breathe. Sinusitis can start from various triggers, such as infection, allergies, or tiny particles entering the nose from the environment. People who frequently suffer sinusitis face many symptoms, including sinus headaches, sore throat, fevers, cough, pressure and pain on the upper face, a stuffy nose, and others.

Sinusitis can worsen, leading to bacterial infection that require treatment with antibiotics. Treating chronic sinusitis is vital for overall health, as if a bacterial case of sinusitis is left untreated the condition poses a risk of leading to life-threatening conditions.

Nasal Polyps

Nasal polyps are common, and for most people, pose no problem and present no symptoms. A nasal polyp is a soft growth of tissue, typically growing in a teardrop shape, that forms within the nose structure or the sinuses. Larger nasal polyps can cause problems, as the size of the tissue blocks normal nose drainage, with mucus building up, potentially leading to a painful infection. The symptoms that may indicate that you have nasal polyps include a constantly stuffy nose, frequent sneezing, a drippy or runny nose, or a reduced sense of smell.

Sinus CT Imaging

Modern imaging technology makes it possible to “map” the sinuses and reveal any blockages or structural abnormalities. The scanner produces a 3D image of your sinus anatomy, an important test for patients who have nasal symptoms. To correctly diagnose and treat a nasal condition, a sinus CT scan may be the appropriate test to identify sinusitis, or evaluate other sinus problems, inflammatory diseases, or in nasal surgery planning.

Nasal Endoscopy

A patient who presents certain symptoms, including ongoing congestion, nasal blockage, sinus infections, polyps, frequent nosebleeds or a limited sense of smell may need to undergo a nasal endoscopy. This test involves the use of a flexible tube and a tiny camera which is inserted into the nasal cavities, with images of the interior of the nose structure digitally produced on a monitor.

This test may be important for both diagnosis and to evaluate the progress of a treatment. In some cases, a nasal endoscopy is the process by which minimally invasive nasal surgery is performed to treat problems such as sinus infections, polyps or other conditions.

Sinus Cultures

A sinus culture may be necessary to evaluate a nasal condition. Certain resistant bacteria may cause a patient to have symptoms such as thick nasal discharge, ongoing congestion, facial pain or pressure, and swelling. A nasal culture can identify bacterial infections and sinusitis. A swab is taken of the abnormal mucous, often endoscopically, and sent to our in-house laboratory. Dr. Zadeh may choose to perform a sinus culture to identify the source of sinus infection. This test may be necessary if a bacterial infection is does not resolve with antibiotics.

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.
