Welcome to the Maryland Nose and Sinus Center

"Our Patients Come First."

Our goal at the Maryland Nose and Sinus Center is to offer a high-quality treatment for all aspects of medical and surgical rhinology and related disciplines, both in adults and children, including medical treatment for nose ailments and sinus disorders, treatment of olfactory disorders and nasal allergy, functional nasal surgery for nasal obstruction, minimally invasive endoscopic sinus surgery, balloon sinuplasty and cosmetic nasal surgery.

The physicians of the Maryland Nose and Sinus Center are known nationally and internationally for their work in and Rhinology. Rhinology (Greek for "rhinos" or "nose") is the study of the nose and sinuses, and concerns itself with all medical and surgical diseases of the nasal passages as well as paranasal sinuses. Dr Shikani trained at the Johns Hopkins Hospital with Dr. David Kennedy (the father of minimally invasive endoscopic sinus surgery in the US). Dr Shikani is the founder of the Maryland Nose and Sinus Center and the director of the Maryland Nose and Sinus Center Rhinology Fellowship Program, and he has performed more than 10,000 nose and sinus surgeries over a 25-year career in otolaryngology. Since 2006, many rhinology fellows from the US and various areas of the world have come to Baltimore to spend one entire year training under Dr Shikani and specializing in the field of rhinology, and have then moved on to become rhinology faculty in their respective institutions. Dr. Todd Hesham did her residency at Georgetown University School of Medicine in Washington, DC, where she was awarded the John Eisenberg Memorial Career Development Award, and the Roy Sessions Award.

The physicians of the Maryland Nose and Sinus Center, Dr Shikani and Dr Todd-Hesham, have published numerous articles and publications in peer review journals and books, and made numerous presentations in national and international meetings, including the American Academy of Otolaryngology national meetings and specialty rhinology meetings in the US and around the world.

What is Balloon Sinuplasty?

Sinus Symptoms

Sinusitis (also called rhinosinusitis) is an inflammation of the sinus lining that prevents normal mucus drainage through the nose. This blockage causes mucus to build up in the sinuses and can lead to very uncomfortable symptoms. Sinusitis symptoms may include:

Balloon Sinuplasty In-Office

Office-based sinus dilation may be a compelling option for patients who decline or are ineligible for traditional OR-based surgery. With Balloon Sinuplasty In-Office, the majority of patients return to normal activity within two days of the procedure.

Frequently Asked Questions About Sinusitis

Here is a list of our top questions that our patients ask us. We have listed them here to answer any questions you may have and even the questions you haven't thought of.

What are the sinuses?

The paranasal sinuses are a group of four paired air-filled spaces that surround the nasal cavity (maxillary sinuses), above and between the eyes (ethmoid sinuses and frontal sinuses), and behind the ethmoids (sphenoid sinuses). The sinuses are named for the facial bones behind which they are located. Humans possess a number of paranasal sinuses, divided into subgroups that are named according to the bones within which the sinuses lie:

The pictures below show the sinus anatomy, detailing the frontal, ethmoid, and sphenoid sinuses.




The paranasal sinuses are lined with respiratory epithelium (ciliated pseudostratified columnar epithelium) that have a muciliary function, which clears bacteria out of the sinuses through the ostial openings (mucociliary clearance).


Maxillary mucociliary clearance


Frontal and ethmoidal mucociliary clearance And Maxillary mucociliary clearance

Blockage of the small sinus openings from swelling, infection, allergy, and other causes can result in sinusitis. The ostiomeatal complex is the most important sinus opening. Any process that causes blockage in this sensitive area can occlude the other sinuses that drain into the ostiomeatal complex.


Ostiomeatal complex obstruction

When obstruction occurs, the mucus is retained in the sinus cavity, providing a medium for bacterial growth. Obstruction also leads to decreased oxygen levels within the sinus, which exacerbates sinus infections from both aerobic and anaerobic bacteria. These changes lead to damage to the sinus lining, leading to further tissue inflammation, which in turn leads to further blockage. These events demonstrate a vicious cycle that leads to chronic sinusitis.

How many sinuses are there?

We have 2 frontal sinuses which are basically behind the brows and the forehead, 2 maxillary or cheek sinuses, 2 ethmoids sinuses which are located between the eyes and finally one sphenoid sinus which is deeper in the back of the nose closer to the brain.

What is a turbinate?

We all have 3 to 4 turbinates in each side of the nose. These are structures inside of the nose that behave like sponges full of blood. They help warming the air we breathe and act as filters for all the particles that are present in the air we breathe. They swell in reaction to many things (allergy, infection, emotions...) creating the feeling of being congested.

Sometimes, the turbinate's fail to shrink ( or decongest) creating a constant feeling of having the nose blocked. Medications and surgeries and help reduce the size of the turbinate's and improve your breathing.

What is chronic rhinosinusitis or chronic sinusitis?

It is one of the most commonly diagnosed chronic illnesses in the United States, more prevalent than heart disease and migraine headaches. More than thirty-five million adult Americans suffered from it. If you have facial pain, nasal congestion, drainage, or post nasal drip for longer than three months, you may have chronic sinusitis.

What are the symptoms of sinusitis?

Symptoms include headache, facial, pain/pressure, facial congestion/fullness, nasal obstruction/blockage, nasal discharge/purulence/discolored nasal drainage, hyposmia/anosmia (decreased smell), purulence in nasal cavity on examination, ear pressure/fullness, fever, halitosis, fatigue, dental pain, cough.

Do I have sinusitis?

A number of symptoms can occur during a sinus infection. If you are experiencing one of these symptoms you are most likely suffering from sinusitis: pain and pressure, difficulty breathing and congestion, and postnasal drip.

Does pain/pressure location indicate anything?

The pain's location relates sometimes to the infected sinus:

Why am I always congested?

Difficulty breathing and congestion are one of the most common complaints in a sinus clinic. The most common reason for this congestion is a common cold because the inside of your nose is all swollen and full of mucus.

Allergies can also cause your nose to be congested during long period of times. Allergy symptoms can be controlled by medical treatment and less frequently by surgery to reduce the size of your turbinates.

A common cause of nasal blockage is also septal deviation which means that the cartilage that separates the nose into a right and left passage is not straight causing a blockage in either side. The treatment of this condition is most of the times surgical. More rarely, nasal congestion can be caused by polyps in the nose or even the tumor. Diagnosis is usually made on endoscopy and on a CAT-scan of the nose and treatment is mainly surgical.

What is Postnasal Drip?

Mucus from the sinuses normally drains in the nose and down the back of the throat before being swallowed. If you have sinusitis, increased secretion by the nose and sinuses results in a larger volume of mucus, which is often thick and yellow or green making us more conscious of this phenomenon.

How do I know if I have allergies?

Symptoms such as itchy eyes, sneezing, and thin postnasal drip are likely due to allergies. You can be tested for allergies to determine what causes allergies to flare up. Finding the culprit help you avoid it. Your doctor can also desensitize you to this special agent reducing the need for allergy medications.

I think that lost my sense of smell, what happened?

The roof of the nasal cavity is lined with the nose has in its roof a special receptors to odor molecules that we breathe in. Loosing sense of smell can be cause by an obstruction of the nose (congestion, infection such as the common cold) or even damage of these receptors by a viral infection or a trauma or surgery or even by an obstruction of the nose by polyps or tumors. Sometimes strokes can cause you to lose your sense of smell.

I think I have a loss of taste.

Most of the people you complaints of a loss of taste have usually a loss of smell (like when you have a cold).In rare case the problem can be coming from the tongue or what is called the taste buds or even from the brain.

Can sinus problems be causing me to cough?

When mucus runs down the back of the throat, it may touch the vocal cords and trigger an involuntary cough response. Sinusitis is sometimes incriminated in persistent cough but other problems and lung infections and reflux need to be ruled out first.

Can Sinus Problems make me feel dizzy?

Sinusitis may block the Eustachian tubes, passageways that connect your ears to the back of your nose. Their function is to equalize pressure between the inside of the ears (or middle ear space) and the outside atmosphere. This can explain why you fill like your ears are full when you are having a sinus infection.

Can I have sinus infection without a fever?

While most of the acute sinus infection or acute sinusitis will cause some king of low grade fever, some will not making fever a very unreliable symptom.

How do you diagnose sinusitis?

Your ENT physician at the Maryland Nose and Sinus Center will perform a physical examination that includes nasal endoscopy using a state-of-the-art sinus endoscope that illuminates the depth of the nasal cavities and allows a clear and direct visualization of sinus pathology.

What is a CAT scan and when do I need it?

Your doctor may order a computed tomography (CT) scan to confirm the diagnosis. It is a radiological technique that uses a series of thin slices of x-ray pictures of the head and sinuses. A CAT scan typically takes 5 to 10minutes to complete and in most cases can be done without the injection of an IV dye. CAT scan is very useful to diagnose and follow up long standing sinus problems. They also help the surgeon planning a safe surgery avoiding critical structures like the brain and the eyes.

On a CAT scan, air is black and bone is white. Gray represents soft tissues and can signify disease (pus, inflamed mucosa, polyps).

What are nasal polyps?

Polyps are small growths attached to the sinus walls and made of inflamed and distorted sinus mucosa. Their precise cause is unknown but they usually occur is severe chronic infection of the sinuses. Their treatment is surgical when they obstruct the nose causing blockage, infection or loss of smell. They also tend to recur.

How can you treat chronic sinusitis?

Treatment is almost never exclusively surgical. While surgery can help ventilate and drain the sinus, medical treatment plays a critical role in the healing process and in maintaining healthy sinus cavities.

Medical treatment includes but is not limited to oral antibiotics, nasal spays, nasal saline rinses, oral steroids as well as topical antibiotics either in the form of a drug eluting gel or a nebulized steroids or antibiotics.

A nebulizer can deliver medications such as antibiotics in high concentrations directly into the sinuses, where they can be most effective sparing sometimes the need for oral treatment.

For a comprehensive review on how to treat sinusitis, please refer to Dr Shikani's article on Medscape: Sinusitis: A Head and Neck Surgeon's Perspective.

What am I to expect during my visit to the Maryland Nose and Sinus Center?

After asking you some questions about your general health and your symptoms, the doctor will perform a physical exam which encompasses most of the times an exam of your ears, your mouth and throat, your face and your neck.

Then, your doctor will most likely do a nasal endoscopy. He'll first spray your nasal passages with a topical numbing medicine (which reduces the tickle sensation and prevents you from sneezing).

Endoscopy helps your doctor see if the mucous membranes are inflamed if you are draining pus, if the turbinates are enlarged, if polyps are blocking the sinuses.

After making the correct diagnosis, your doctor will treat your condition accordingly. If you have sinusitis, he will prescribe an antibiotic and a nasal spray. If symptoms persist, the treatment can be repeated, with different medications. Typically, if the condition persists more than 3 months it becomes known as chronic rhinosinusitis, and some type of surgical intervention may be warranted.

What is balloon sinuplasty?

Balloon sinuplasty is an endoscopic surgical procedure for the treatment of blocked nasal sinuses. Patients diagnosed with chronic sinusitis but not responding well to medications may be candidates for balloon sinuplasty. Balloon sinuplasty technology was developed by Acclarent, Inc., and was brought to market in 2005, after FDA approval. Dr Shikani has done early research in balloon sinuplasty, sponsored by Acclarent in order to help improving the technology and performed the first 20 cases of balloon sinuplasty in Maryland in 2006 at the Union Memorial Hospital.

Balloon sinuplasty uses a small, flexible balloon catheter to enlarge sinus passageways. When the balloon is inflated, it widens the walls of the sinus passageway, with the goal of restoring normal sinus drainage without damaging the sinus lining.

Sinus surgery with Balloon Sinuplasty may be performed safely in a hospital, in an outpatient surgery center (under general anesthesia), or in a doctor's office (under local anesthesia). The surgeon and patient will determine whether the procedure is best done under traditional general anesthesia or local anesthesia depending upon the patient's medical history and the type of sinus disease that needs to be managed.

When performing Balloon sinuplasty, the physician inserts a sinus guide catheter through the nostril to gain access to the sinus ostia (openings) under endoscopic visualization. The endoscope allows the physician to see through the nasal passages to the sinus cavities to ensure that he/she is inserting the catheter into the proper location. A sinus guide wire or sinus illumination system is then introduced into the targeted sinus via the sinus guide catheter. The sinus illumination system provides a targeted fiber optic light transmission that helps the physician place the sinus guide catheter in the correct place. When the Balloon Sinuplasty system was introduced in 2005, illuminated wires did not exist and surgeons confirmed the location of the wires with low level x-ray using fluoroscopy.

Once access to the intended location is confirmed by light or fluoroscopy, a balloon catheter is introduced into the sinus cavity over the sinus guide wire or sinus illumination system and positioned in the blocked ostium for inflation. Once the position has been confirmed visually, the balloon is inflated to unblock the narrow or blocked ostium. The balloon is then deflated and removed. Next, an irrigation catheter may be advanced over the sinus guide wire or sinus illumination system to flush out the sinus of any mucus or pus. Finally, the sinus irrigation catheter is removed from the sinus to allow the sinus cavity to drain any mucus and/or pus. Newer balloon catheters have the irrigation system incorporated into the balloon making the procedure simpler with fewer steps.

What is endoscopic sinus surgery?

Endoscopic sinus surgery (ESS) came into existence because of pioneering work of Messerklinger and Stamberger (Graz, Austria, 1970's). Other surgeons have made additional contributions (first performed in USA by Kennedy in 1985). It is done either under local or general anesthesia, depending on the extent of the procedure, and using an endoscope, disease and obstructing bone and polyps are removed from the nose and sinus cavities are opened. The physicians at the Maryland Nose and Sinus Center have performed several thousands of sinus surgeries over the last 20 years. In our hands, the success rates of primary endoscopic sinus surgeries are superior to 90%.


Endoscopic sinus surgery uses special instruments to remove bone and mucosal disease tissue from infected sinuses.

What is the recovery time from sinus surgery?

Recovery time is highly variable among individuals and according to the type and extent of surgeries. Balloon sinuplasty is now an in-office procedure that is under local anesthesia that usually does not require packing. Recovery is immediate and patients are back to work immediately. Endoscopic sinus surgery is an operating room procedure that usually requires packing. Packs are removed one week after surgery and nasal cavities are suctioned. By this time most of the patients would have resumed near-normal life.

What instructions should I follow after surgery?

In the immediate post-op period you should refrain from any vigorous physical activity which may increase the risk of bleeding. You will have antibiotics and pain medications, and you will be asked to rinse your nose with nasal saline.

What are the complications of sinus surgery?

Complications of sinus surgery are. Starting from the most common:

Very rare but serious complications are extremely rare and include the following:

What happens if I have severe bleeding after sinus surgery?

Bleeding after sinus surgery (epistaxis) is an uncommon occurrence. It came be minimized by meticulous surgical technique by the surgeon, thorough knowledge of the anatomy so that to avoid hitting any of the large arteries, and precise use of the surgical instruments during the procedure. Yu can help by avoiding any blood thinners (such as aspirin, ibuprofen, Plavix or Coumadin) immediately before the surgery. In case significant bleeding is encountered, this can be controlled by nasal packing. Dr Shikani is an expert on epistaxis and has done extensive research and developed a novel nasal packing for epistaxis, that consist of Chitosan*, a natural cationic polysaccharide with well-known powerful hemostatic properties that is used by the US Army soldiers for stopping bleeding after combat wounds.

I have had surgery by another ENT doctor but am not better. What is wrong with my sinuses and what can I do about it?

When performed correctly, endoscopic sinus surgery (ESS) is highly effective for the treatment of chronic rhinosinusitis (CRS), with a 97-98% improvement in symptoms reported during the 12 months after surgery. However the outcome is affected not only by the skills of the surgeon, but also by certain factors that the patient controls (such as allergies, smoking and GERD or Gastro-Esophageal Reflux Disease). Even when FESS is performed by a good surgeon, long-term follow-up shows that the beneficial effects dissipate over time with gradual worsening of the sinusitis symptoms in 5-25% of patients after 3 years, and 3-14% of patients requiring revision ESS. Patients who continue to show clinical evidence of sinusitis, despite surgery and intensive medical treatment are labeled as having refractory CRS (or recalcitrant CRS) and often pose a therapeutic challenge to the treating rhinologist. Dr Shikani's research for the last 3 years has focused on the pathophysiology and on exploring treatment options for refractory sinus conditions. For those frustratingly difficult sinus cases, he has developed a novel multi-factorial treatment protocol (called "Rhinotopic Therapy" protocol*), which includes topical nasal nebulization and a hydroxyl-ethyl cellulose biodegradable gel that releases antibiotics and corticosteroids inside the nasal cavity. Rhinotopic Therapy has proven effective in reversing mucosal changes and promoting healing of the mucosal surface epithelial barrier in refractory CRS.

What is Image-Guided Navigation Surgery?

Image-guided surgery is a recent development that you may benefit from, particularly if you need an advanced surgical procedure done. It is a technological tool designed to help surgeons guide their instruments through the sinus cavities with millimeter accuracy while showing them exactly where they are in the nose on a monitor. This requires doing a preoperative sinus CAT scan, performed according to the machine protocol.


How can I get my septum fixed?

The surgical procedure to correct a deviated septum is called a septoplasty or nasal septum reconstruction, and is performed under general anesthesia. The surgeon makes an incision just inside the nostril, lifts the mucous membranes on the septum, and remodels or removes the portion of the cartilage and bone that's deviated. Then the surgeon places dissolvable stitches or inserts nasal packing at the conclusion of the procedure. Complications are rare but may include bleeding, infection, perforation and over resection of the septum.

What surgery can be done for the turbinates?

They can be shrunk with a radio-frequency needle by a process called radiofrequency coblation. This is a relatively new option which delivers a measured dose of electrical energy to heat and shrink swollen turbinate tissue. This procedure is usually done under local anesthesia. Alternatively, enlarged inferior turbinates can be remedied with a surgical procedure known as sub-mucous resection, in which a portion of the obstructing turbinate bone is removed with the patient under general anesthesia.

What can you tell me about pituitary tumors and the surgery to remove them?

Pituitary adenomas are tumors that occur in the pituitary gland, and account for about 15% of intracranial neoplasms. Tumors which exceed 10 mm in size are defined as macroadenomas, and those smaller than 10 mm are referred to as microadenomas. Most pituitary adenomas are microadenomas, which often remain undiagnosed, and have an estimated prevalence of 16.7% (14.4% in autopsy studies and 22.5% in radiologic studies). Pituitary tumors are classified into secretive and non-secretive based on plasma hormone levels. Hormone secreting pituitary adenomas cause one of several forms of hyperpituitarism. The specifics depend on the type of hormone. Some tumors secrete more than one hormone, the most common combination being GH and prolactin. In addition, a pituitary adenoma may present with visual field defects, classically bitemporal hemianopia. It arises from the compression of the optic nerve by the tumor. The specific area of the visual pathway at which compression by these tumors occurs is at the optic chiasma. Also, a pituitary adenoma can cause symptoms of increased intracranial pressure. Prolactinomas often start to give symptoms especially during pregnancy, when the hormone progesterone increases the tumor's growth rate. Headaches may be present.

Treatment options depend on the type of tumor and on its size:
