Laser procedure effective in correcting nasal blockages associated with deviated septum


A new laser procedure that requires only local anesthetic is effective in treating nasal passageway obstructions associated with a deviated nasal septum, according to an article in the July-September issue of The Archives of Facial Plastic Surgery, one of the JAMA/Archives journals. The procedure uses heat generated by a laser to soften cartilage abnormalities so that they can be flattened or shaped to clear the nasal passages.

The septum is the cartilage wall that divides and separates the nostrils. People who have a deviated septum may have a hole in the septum, or other malformations that can block the nasal passageways and can cause varying degrees of difficulty with breathing. Traditional surgery to solve these problems uses a scalpel to cut away flaps inside the nose and reshape the cartilage manually. Stitches are needed to close the surgical wounds. The procedure is costly and the patient may need time off from work to recover. The new procedure uses a laser to heat the malformations until they are soft enough to be pressed or formed so that they aren’t blocking the nasal passageways.

Yuri Ovchinnikov, M.D., of Moscow State University, Russia, and colleagues used the laser procedure on 110 patients between 11 years old and 66 years old. Patients were followed up for an average of 18 months.

The laser outpatient procedure lasted 6 to 8 minutes. The researchers found that 84 (76 percent) patients had an improvement in their airways, and with symptoms associated with nasal blockages. The authors write, "After 7 to 10 days, the septal cartilage in all patients tended to recover some of the initial deformity (shape-memory effect). Two to 3 weeks later, the cartilage started to restraighten. The septum reached a stable shape after 3 to 4 weeks. This shape change remained stable throughout the observation period (2 to 3 years)."

In 27 (24 percent) of the patients, abnormalities treated with the laser procedure resumed their original shapes. The authors found that these patients had spurs or other abnormalities, didn’t receive uniform heating of the cartilage and had other disorders, like rhinitis, a chronic allergic condition causing breathing problems, nasal irritation and runny nose.

The researchers conclude "Our results in 110 patients using this new laser-based procedure to reshape the nasal septum may provide an alternative to classic operations for reducing morbidity, operating room times, and the economic impact of time lost from work."

Im Focus: Space observation with radar to secure Germany's space infrastructure

Satellites in near-Earth orbit are at risk due to the steady increase in space debris. But their mission in the areas of telecommunications, navigation or weather forecasts is essential for society. Fraunhofer FHR therefore develops radar-based systems which allow the detection, tracking and cataloging of even the smallest particles of debris. Satellite operators who have access to our data are in a better position to plan evasive maneuvers and prevent destructive collisions. From April, 25-29 2018, Fraunhofer FHR and its partners will exhibit the complementary radar systems TIRA and GESTRA as well as the latest radar techniques for space observation across three stands at the ILA Berlin.

The "traffic situation" in space is very tense: the Earth is currently being orbited not only by countless satellites but also by a large volume of space...

Im Focus: Researchers Discover New Anti-Cancer Protein

An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.

The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...

Im Focus: Researchers at Fraunhofer monitor re-entry of Chinese space station Tiangong-1

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.

Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...
