The ORBEYE 4K 3D Orbital Camera System
Amongst the marketed exoscopic devices, the ORBEYE 4K 3D platform (Sony
Olympus Medical Solutions, Tokyo, Japan; FDA approved) is characterized
by one of the highest magnification powers (26X with the 55” screen)
keeping a full size 4K image resolution along the whole range of
available enlargements. Furthermore, the motorized supporting arm makes
its movements easy and accurate and the inclusion of the Narrow Band
Imaging tool, developed in the gastroenterological setting and already
widely used in the upper aerodigestive tract,3 permits
a live intraoperative control of the margins dealing with oncologic
resections. During the COVID-19 pandemic, the main advantage of such
device is the possibility to avoid the removal of PPE as goggles and
face shields approaching microsurgical procedures, with no decreased
quality of vision or depth perception if compared with the traditional
settings.
Our experience is derived by a case series of twelve successfully
treated patients enrolled in September 2019: three tonsillectomies
(Figure 1A-C ), three laryngeal tumors transoral laser
resections (Figure 1D-F ), one parapharyngeal tumor transoral
resection (Figure 1G-I ), three glottic phonomicrosurgical
procedures (Figure 1J-K ) and two free flaps harvesting with
microvascular anastomosis (Figure 1L ).
In the context of pharyngo-laryngeal oncologic transoral procedures, the
ORBEYE 4K 3D guarantees a clear view especially for tumors of the
tonsillar area or lateral oropharyngeal wall, with no need of angled
telescopes coupled to the camera. Moreover, by means of ORBEYE 4K 3D and
a Tulium-diode fiber laser as cutting device, both an excellent cutting
and coagulation power are ensured, being possible to achieve very
accurate resections with a minimally invasive approach.
The high magnification power with 4k resolution also allows the
execution of microsurgical vascular anastomosis for free flaps
reconstructions, suggesting its easy application as system of vision, as
already tested also by other authors, in several microsurgical fields as
otoneurosurgery,4 reconstructive
surgery,5 ophthalmology or
neurosurgery.6 Furthermore, its excellent lighting and
image definition features permit a clear view also in the narrow
corridor of a laryngoscope, ensuring precise phonomicrosurgical
procedures, also with a better ergonomics; this suggests, in centers
already equipped with this technology, a benefit also for elective
transoral procedures after the end of the COVID-19 pandemic.
