Septoplasty and Septal Deviation

Septal deviation is a common condition, with a significant portion of the population having their septum deviate to one side or the other.  Commonly some degree of nasal trauma may cause a deviated septum.  Many people are asymptomatic from this, however a few can have nasal obstruction symptoms on the side that is deviated.  In these patients, septoplasty (i.e straightening the septum), can be performed.  It is usually an outpatient procedure, performed under general anesthesia.  After the operation, the patient can breathe better on the affected side.  If the deviated septum is more posteriorly placed, endoscopic septoplasty is a good option for the patient.  This approach can be done without packing or splints afterwards, and the recovery is easier.  Commonly an inferior turbinoplasty is performed concurrently because the turbinates can be swollen due to allergies, or to compensate for the extra space on the non deviated side.

Endoscopic Septoplasty

Endoscopic septoplasty is a newer technique where an endoscope is used to visualize the nasal cavity to straighten the nasal septum. Most people’s septum will be deviated to one side or the other, which is not a cause for concern. However in some people the deviation is significant enough that it results in nasal obstruction. If this is the case, then they would be a candidate for septoplasty. The incision is made on the side of the deviation, 1-2cm back from the most forward part of the septum. The mucosa is lifted up on this side, then the cartilage is incised and the flap is lifted on the other side. Deviated bone and cartilage is removed, and the deviation is reduced. The flaps are stitched together with an absorbable mattress suture. The vast majority of the time, stents and packing are not required.   This results in minimal post op pain, and Tylenol is adequate for postoperative pain control.   Neilmed rinses are begun the next day.   Not all people are candidates for endoscopic septoplasty, namely those with significant forward deviations, where a traditional approach is indicated. Please see the link below for an intraoperative video.   Frequently endoscopic septoplasty is performed concurrently with endoscopic sinus surger.y  In fact, inadequate septoplasty can be a reason for failure of surgery due to limited visualization of the sinuses while performing endoscopic sinus surgery.

Sinonasal Tumors

Tumors of the nasal cavity and paranasal sinuses are not common in the general population, but are commonly encountered in a rhinology practice.  When unilateral symptoms such as nasal obstruction, smell loss and epistaxis are present then evaluation by an otolaryngologist would be prudent.

The most common sinonasal tumor is an inverted papilloma.  These are also known as Schneiderian papillomas.  Fortunately these are benign tumors, but they can turn into squamous cell carcinoma eventually if not excised.  They can occur throughout the nasal cavity and paranasal sinuses.    Inverted papillomas can be quite large, but usually will have a distinct attachment site that can be identified on CT imaging by looking for an area of hyperostosis.  MRI imaging is helpful to further define the extent of tumor and to distinguish between tumor and blocked secretions.  Most tumors can be excised using traditional endoscopic sinus surgery techniques, and extended endoscopic approaches such as frontal sinus drillout and endoscopic medial maxillectomy can be used to remove tumors without external incisions.  Treatment of the attachment site should be treated with excision, drilling or cauterization to ensure complete removal of all of the tendrils of tumor to prevent recurrence.

Allergic fungal sinusitis can mimic a tumor with its unilaterality, however it is uncommon in the West.

Sinonasal malignancies are thankfully rare (1:500,000 to 1:1,000,000), but prompt diagnosis and management are key to ensure survival.  Squamous cell carcinoma, melanoma, sinonasal undifferentiated carcinoma, esthesioneuroblastoma, lymphoma and adenocarcinoma are the most common sinonasal malignancies.  For most sinonasal malignancies, except lymphoma, treatment is usually surgical resection, and depending on the tumor pathology, post operative radiation and chemotherapy.

Is One Ear Better Than The Other?

When it comes to language, it may be true. According to recent research by audiologists at Auburn University, there could be an advantage to listening with our right ears, especially for children and noise-distracted adults.

The phenomenon is known as the right-ear advantage: Speech heard through the right ear reaches the part of the brain that processes it in about 20 milliseconds. Speech heard through the left ear, however, takes anywhere from 3 to 300 milliseconds longer to reach the same part of the brain.

Why? The speech we hear in our right ears can travel directly to the left hemisphere of our brains, which is generally thought to be where language is processed. Speech received by the left ear takes a less direct route, resulting in a lower processing speed. From the left ear, sound signals travel first to the right hemisphere of the brain. Then, they are relayed via the corpus callosum — a broad band of nerve fibers that connects the hemispheres — which finally passes them onto the left hemisphere. This means that, even though we can hear with both ears, our brains more efficiently process speech heard with the right ear because those signals arrive more quickly.

In children younger than 11, the right ear advantage is the most noticeable. A typical 7-year-old will correctly repeat information heard by the right ear about 70 percent of the time, compared to only about 55 percent of the time when the information is heard by the left ear. A 9-year-old is accurate about 80 percent of the time with their right ear and 75 percent with their left. An 11-year-old is about as accurate as most adults, which is close to 90 percent in both ears.

The right-ear advantage is more apparent in children whose myelin membranes are less developed. The myelin is an insulating sheath that facilitates faster impulse transfers through the corpus callosum. Because the myelin develops with age, the right-ear advantage tends to dwindle over time. In fact, for most adults this phenomenon isn’t noticeable unless we are processing complex information that exceeds our basic memory capacity.

When adults hear the same speech in both ears at the same time, there is no perceivable advantage with the right ear. Rather, problems occur when we receive signals that have to compete with each other. When adults are trying to pay attention to multiple sources of speech at the same time, memory capacity is quickly exceeded, and the right-ear advantage comes back into play. In these studies, distracted adults are shown to have anywhere from a 7 to 40 percent advantage when using their right ear.

With this in mind, the next time you lean in to talk to someone in a noisy room, check which ear you’re leaning towards — is it the right one?

Excessive Tearing Caused by Nasolacrimal Duct Obstruction

The lacrimal apparatus is what is responsible for creating tears and moving them from the eyes to the nose. It is possible for the lacrimal system to become obstructed and prevent tears from draining naturally. This is known as nasolacrimal duct obstruction. When tears cannot drain, this can present as excessive tearing, or epiphora, and it can occur either intermittently or continuously.

Excessive clear tearing is the most common symptom of nasolacrimal duct obstruction. Occasionally it will also be accompanied by a mucus discharge from the eyes. Dacryocystitis is a less common symptom — this is an infection of the region between the eye and nose, and can occur repeatedly in those with a lacrimal blockage. Patients with dacryocystitis often report tenderness in the area between the eye and nose.

There are several possible causes for nasolacrimal duct obstruction. The most obvious is facial trauma, which can create scarring inside of the lacrimal apparatus or tear the nasolacrimal duct. In surgery to correct facial trauma deformities, injury to the lacrimal apparatus may occur unintentionally. Other types of facial surgery such as sinus surgery and head and neck cancer surgeries can also injure the lacrimal system.

Another cause of nasolacrimal duct obstruction is bacterial infection, which leads to inflammation within the duct. Infection and inflammation can lead to scarring, which can reduce passage within the duct or block it entirely. Autoimmune diseases can also cause inflammation in the nasolacrimal duct, which can create a blockage without any infection.

Although the above causes are easy to understand, more often than not, nasolacrimal duct obstruction occurs without any apparent cause. Middle-aged individuals are most likely to experience it, and some researchers believe osteoporosis and hormone changes may play a role.

To determine if you have an obstruction in your nasolacrimal duct, a rhinologist may apply fluorescent dye in the corner of an eye to see if saline is transferring into your nose. If the dye is not noticeably passing through your lacrimal apparatus, an injection of the same substance may be attempted into the tear duct. If the duct still appears obstructed, an x-ray can be used to determine the location of obstruction.

If there is a physical obstruction, your rhinologist may perform a dacryocystorhinostomy (DCR) to remove it. A DCR creates a direct opening from the lacrimal sac (within the lacrimal apparatus) to the nasal cavity. The opening is held open with either sutures or stents, and it allows the tears to drain naturally into the nasal cavity. The procedure can be done externally, through an incision between the nose and eye, or endoscopically, which can be less painful and won’t leave any visible scarring. DCR is a procedure with minimal risks and postoperative effects. Patients can expect minimal bleeding and some scarring within the nose, and those who have the procedure enjoy a 90 percent success rate.

If you are having issues with excessive tearing, please call and make an appointment with one of the specialists at Nevada ENT and the Reno Tahoe Sinus Center. We can help determine the source of your symptoms and give you information on treatment options individually tailored to your situation.

How to Handle Your Summer Allergies

Allergies can make you miserable. With itchy eyes, a runny nose, sneezing and congestion, enjoying yourself during beautiful summer months can be difficult. Try these simple tips to keep your summer allergies under control and have fun this summer!

Keep Indoor Air Clean

Unfortunately, there isn’t a product that can magically eliminate all allergens in your home. However, when using the air conditioning in the house or car regularly, changing the air filters and keeping the indoor air dry with a dehumidifier can greatly help.

Reduce Exposure

Try and reduce your exposure to things that can activate your allergies like staying indoors on dry or windy days. Understanding that spending all summer indoors is impossible, plan ahead and look at local weather or pollen levels.

If outside chores are calling your name, either wear a pollen mask or delegate the chores like lawn mowing or weed pulling. After outdoor chores or activities, remove the clothes you wore outside and shower to remove all the pollen from your hair and skin.

Rinses Those Sinuses

Rinsing your sinuses, or nasal irrigation, is a beneficial way to relieve symptoms for those who struggle with allergies or just general nasal congestion. Nasal irrigation is flushing out your nasal cavity with a saline solution. The solution is a simple mixture of purified water and salt, used in combination with a squeeze bottle or a neti pot. Directly rinsing your sinuses or nasal passages will flushes out mucus and allergens in your nose.

Over-the-counter remedy

If the tips above aren’t cutting it, there are several types of nonprescription medications that can alleviate your allergy symptoms.

  • Oral antihistamines can help relieve sneezing, itching, a runny nose and watery eyes
  • Decongestants, such as pseudoephedrine, can provide temporary relief from nasal stuffiness
  • Nasal spray can ease allergy symptoms and doesn’t have serious side effects, though it’s most effective when you begin using it before your symptoms start

Consult a Doctor

For some, taking precaution or using over-the-counter medications isn’t enough to alleviate their allergy symptoms. So, consult your doctor to determine the best course of action for your allergies, whether they are seasonal or year around.

How to Protect Hearing During Summer Outdoor Activities

Summer; the best time for outdoor activities like swimming, live concerts, fireworks and even yard work. To get the most out of your summer but also to protect your hearing, here are some preventative measures to keep in mind during these summer activates.

Live Concerts

Outdoors concerts are the best during the summer but can be just as harmful because of the high volume of decibels during the concerts.

Decibels are a unit used to measure the intensity of a sound or the power level of an electrical signal by comparing it with a given level on a logarithmic scale.

The typical person can generally accept 85 decibels for a maximum of eight hours a day, followed by at least a couple hours of recovery time. Most live concerts are at a volume of 100 to 110 decibels which decrease the length of exposure time.

There are two options for all concert goers, placing oneself as far away from speakers as possible or wearing ear plugs. Earplugs can decrease the noise by 20 to 30 decibels.

Both are good options to avoid ringing in the ears after the concert has ended.

Fireworks

Between Fourth of July, baseball games and local events, fireworks are a staple during the summertime. Although fireworks produce between 140-150 decibels, they generally do not cause problems because the explosions are short-lived and happen in the sky.

However, it’s always better to be safe than sorry. Keeping your distance, around 500 feet, is an easy way to still enjoy the beautiful show but also keep your hearing safe.

Using earplugs is an inexpensive and efficient way to protect your hearing. Various types of earplugs are able to reduce different level of decibels.

Water Activities

The best way to cool off can also be the most common cause of ear trouble during the summer. Swimming in any type of water can cause water to get trapped in the middle ear.

The middle ear is the part between the eardrum and the oval window. It transmits sound from the outer ear to the inner ear. Getting water trapped in the middle ear can cause an infection to develop.

Wearing earplugs or custom-molded ones can prevent trouble or pain.

Outdoor Equipment

Equipment like lawnmowers and weed whackers can produce up to 100 decibels so wearing earplugs is a key protective measure. Some people prefer to listen to music through headphones while doing yard work, this isn’t the same as using earplugs and can be harmful.

Listening to music requires the music to be louder and drown out the sound of the equipment.

Be aware of your proximity to the loud sound and remember to use ear plugs if you need to. There are a variety of earplugs that are best for different types of activities including swimming and attending concerts.
