Novel Video-Laryngoscopes Help Visualize Key Anatomy

Next-generation laryngoscopes minimize strain and maximize performance for ear, nose and throat (ENT) specialists and speech language pathologists.

The Olympus Medical (Olympus; Tokyo, Japan) ENF-VH2 and ENF-V4 video rhino-laryngoscopes are designed to provide detailed images within a broad, luminous field of view. The ENF-VH2 produces high-resolution images that are HD-compatible, and the ENF-V4 offers a slim design with a diameter tip of 2.6 mm, allowing detailed observation of the mucosa via built-in narrow band imaging (NBI), which highlights minute vascular and mucosal patterns using only wavelengths absorbed by hemoglobin. The devices also promote patient comfort, which is especially important in swallowing evaluations as patients are required to eat and drink as part of the procedure.


Slim and lightweight, both devices feature an ergonomic grip and control section that allows physicians and therapists to insert the tube more linearly in relation to the patient, thus helping to reduce friction between the scope and the mucosa and facilitate a smoother, more efficient insertion with either the left or right hand. The rhino-laryngoscopes continuously capture still images, automatically selecting the sharpest available image when the pre-freeze button is pressed. Both scopes can connect to the hospital electronic medical record (EMR) network using the Olympus nCare medical recorder and VaultStream medical content management system.

“Probably the most exciting aspect of using video during swallowing examinations is that the patient becomes an active partner in the healing journey,” said Stephanie Dodson Mataya, MSc, CCC/SLP, an Olympus fiberoptic endoscopic evaluation of swallowing (FEES) educator. “The biofeedback mechanism is invaluable, allowing patients to see what's happening as they swallow. The speech pathologists on our team are always pleased with advancements in handling and ergonomics.”

“These new generation rhino-laryngoscopes not only continue to build on the outstanding imaging technologies and light modalities such as NBI, but also improve the handling and ease of insertion, helping enable a better experience for healthcare providers and patients alike,” said Randy Clark, president of the medical surgical group at Olympus America. “These are critical factors in helping achieve what has become known as the Quadruple Aim, which adds provider job satisfaction to the three pillars of good patient outcomes, cost reduction and patient satisfaction.”
