With growing concerns for radiation exposure, the use of high-frequency ultrasound has increased in the recent times. Ultrasound allows real-time imaging of soft tissues of the neck, thyroid gland, parathyroid glands, and lymph node characterization. In addition, ultrasound is also used for fine-needle aspiration biopsy of thyroid masses and other soft tissue lesions.ForewordVikram Dogra10.1016/j.cult.2012.01.001Ultrasound Clinics 7, 2 (2012)2012-04-01Ultrasound Clinics2012-04-0172S1556-858X(11)X0007-5xixihttp://www.ultrasound.theclinics.com/article/PIIS1556858X11001599/abstract?rss=yesThorough knowledge of the complex anatomy of the head and neck is essential to understanding the ultrasonographic appearance of this region. The intimate familiarity with anatomic structures obtained by performing surgical procedures makes active radiographic imaging modalities like ultrasound especially suited for use by surgeons. An understanding of the normal sonographic appearance of head and neck structures is critical to recognizing abnormal pathology.Head and Neck Anatomy and Ultrasound CorrelationChristopher Klem10.1016/j.cult.2011.12.001Ultrasound Clinics 7, 2 (2012)2012-01-03Ultrasound Clinics2012-01-0372S1556-858X(11)X0007-5161166http://www.ultrasound.theclinics.com/article/PIIS1556858X11001605/abstract?rss=yesThis content is designed to acquaint the clinician with some of the more common ultrasonographic manifestations of clinical conditions that the otolaryngologist is likely to encounter in a general practice. The clinician requires a thorough knowledge of head and neck anatomy to best interpret the variations from normal structures demonstrated on ultrasound. A knowledge of sonographic artifacts may assist the examiner in properly identifying the process under review. Ultrasonography may be the best imaging study for certain organs. In many instances it is the first clinical study that directs further imaging. By providing the clinician with clues as to the underlying pathology, it allows a more efficient direction in determining which aspiration techniques to use.Interpretation of UltrasoundRobert A.

Although its use has traditionally been the domain of radiologists, surgeons and endocrinologists are increasingly integrating this technology into their daily clinical and operative practice. This article provides an overview of the relevant uses and indications for ultrasound in various thyroid diseases, describes characteristic ultrasound findings in these diseases, and reviews the relevant literature and guidelines concerning its uses.

Emphasis is now placed on minimally invasive and focused parathyroidectomy. In conjunction with functional sestamibi scanning, ultrasonography permits accurate localization of enlarged parathyroid glands in the vast majority of patients with hyperparathyroidism. Consequently, ultrasound technology applied to parathyroid pathology facilitates directed surgical therapy and minimally invasive applications. As such, ultrasonography holds great promise as a tool that enables cost-effective and advanced patient care.Techniques for Parathyroid Localization with UltrasoundLisa Lee, David L.

While ultrasonography is most commonly used for imaging of thyroid pathology, it also can be utilized in a host of diagnostic and therapeutic procedures. This article reviews the office-based ultrasound-guided procedures in the head and neck and discusses technical considerations for performing these interventions.

High-resolution ultrasound machines have been reduced to the size of a laptop computer. Ultrasound can be adopted by otolaryngologists for use within the clinic and the operating room. Ultrasound offers several advantages to the pediatric patient population. It is well tolerated and adds a degree of precision to the physical examination. It can be done repeatedly as lesions evolve and treatment is performed. It is valuable for guidance and therapeutic treatment of lesions in the operating room. It is likely that ultrasound use will continue to rapidly grow and evolve as a tool within the field of otolaryngology.Head and Neck Ultrasound in the Pediatric PopulationVeronica J. Rooks, Benjamin B. Cable10.1016/j.cult.2011.12.007Ultrasound Clinics 7, 2 (2012)2011-12-30Ultrasound Clinics2011-12-3072S1556-858X(11)X0007-5229237http://www.ultrasound.theclinics.com/article/PIIS1556858X11001666/abstract?rss=yesIncreased use of ultrasonography of the head and neck by clinicians has resulted from more compact, higher resolution ultrasound machines that can be more readily used in the office setting. Palm-sized machines are already used for vascular access and bladder assessment. As the resolution of these machines becomes adequate for head and neck assessment, ultrasonography is likely to become a routine adjunct to the office physical examination. Further techniques to reduce artifact beyond spatial compounding, second harmonics, and broadband inversion techniques are likely to be developed to improve ultrasound images. Manual palpation using the ultrasound transducer or “sound palpation,” using sound to recreate vibration provides information on tissue “stiffness,” which has been successfully used to distinguish between benign and malignant lesions in the head and neck (particularly thyroid nodules). Microbubble contrast-enhanced ultrasound provides improved resolution of ultrasound images. Three- and four-dimensional ultrasonography provides for more accurate diagnosis. The ability of microbubbles with ligands affixed to their outer surface to target specific tissue makes them excellent delivery vehicles. DNA plasmids, chemotherapy agents, and therapeutic drugs can be released at a specific anatomic site. The motion of microbubbles stimulated by ultrasound can be used to increase drug penetration through tissues and has been shown to be effective in breaking up clots in stroke patients (without increased risk). High-intensity focused ultrasound can be used to create coagulation necrosis without significant damage to adjacent tissue. It has been effectively used in neurosurgery and urology, but its effectiveness in the head and neck is still being determined. A prototype for surgical navigation with ultrasound has been developed for the head and neck, which allows real-time imaging of anatomic surgical changes.Emerging Technology in Head and Neck UltrasonographyMichael R.

The review comprises 2 main subject areas: the use of ultrasonography related to assessment and management of the airway, and the use of ultrasonography related to nerve blockade for ENT surgery. The relevant sonoanatomy and suitable probe placement are illustrated in relation to applicable regional anatomy (they are not discussed). The possible value of the use of ultrasonography to improve existing clinical practice in these areas is explored.Head and Neck Ultrasound: Applications Relevant to Anesthesia and Intensive Care MedicineJames S.
