Office-based ultrasound-guided FNA superior in diagnosing head and neck lesions

01.03.2010
Office-based, surgeon-performed, ultrasound-guided, fine needle aspiration (FNA) of head and neck lesions yields a statistically significant higher diagnostic rate compared to the standard palpation technique, indicates new research in the March 2010 issue of Otolaryngology – Head and Neck Surgery.

FNA is a diagnostic procedure used to investigate superficial lumps or masses. In this technique, a thin, hollow needle is inserted into a mass to extract cells for examination. FNA biopsies are a safe minor surgical procedure.

Often, a major surgical (excisional or open) biopsy can be avoided by performing a needle aspiration biopsy instead. FNA biopsies in the head and neck have also proven to be an invaluable tool in establishing the diagnosis of lesions and masses from a broad range of sites, including the thyroid, salivary glands, and lymph nodes.

The efficacy of ultrasound-guided FNA has been well documented in many areas of the body, leading to its acceptance as the standard of care among radiologists and many cytopathologists. However, while the utility of ultrasound in the head and neck is widely appreciated and employed by the radiology community, clinicians in the United States have not embraced office-based ultrasound. The study authors sought to provide additional evidence and support for this procedure in order to ensure appropriate use by the clinical community.

In this randomized, controlled trial of 81 adults, researchers divided participants into two groups, using either ultrasound-guided or traditional palpation-guided FNA to evaluate an identified head and neck mass. The researchers then measured variables and outcomes for tissue adequacy rates, tissue type, and operator variability.

Following three passes using either palpation or ultrasound-guidance, a comparative tissue adequacy rate of 84 percent for ultrasound-guidance (versus 58 percent for standard palpation) was established. With regard to tissue type, a statistically significant comparative diagnostic advantage for ultrasound guidance was observed in thyroid tissue, while remaining statistically insignificant for lymphatic and salivary tissues.

The authors write, "With respect to FNA of palpable head and neck masses, ultrasound guidance in the hands of the clinician yields a statistically significant improved specimen adequacy rate after three passes, when compared to traditional palpation technique. This represents a discernable clinical benefit for the patient in terms of reducing the number of passes required, as well as the need and cost for a repeat office FNA or a referral for ultrasound guidance."

About the AAO-HNS

The American Academy of Otolaryngology – Head and Neck Surgery (www.entnet.org), one of the oldest medical associations in the nation, represents nearly 12,000 physicians and allied health professionals who specialize in the diagnosis and treatment of disorders of the ears, nose, throat, and related structures of the head and neck. The Academy serves its members by facilitating the advancement of the science and art of medicine related to otolaryngology and by representing the specialty in governmental and socioeconomic issues. The organization's vision: "Empowering otolaryngologist-head and neck surgeons to deliver the best patient care."

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
