The SmartXide² ENT is DEKA’s ENT configuration of the SmartXide² platform: an RF-excited CO₂ laser source with exclusive PSD® pulse shaping, delivered through a 7-mirror titanium articulated arm and driven from a 15.6″ colour touchscreen.
On that arm sit the EasySpot Hybrid micromanipulator and the HiScan Surgical scanning system, which together give the surgeon control over cutting length, ablation area, treatment depth and coagulation, with minimal thermal damage to perilesional tissues and no carbonisation of the cutting edges.
A high power 980 nm diode module can be added at any time, bringing fiber-optic reach to anatomy the articulated arm cannot address — the middle ear for the “ONE SHOT” stapedotomy technique, and the nose for turbinate work.
Pulse Shape Design generates variable peak pulses with different structure, duration and power, adapting the source to the clinical condition. U-Pulse and “Real CW” are the modes most commonly used in ENT surgery.
An additional wavelength that expands the range of available procedures, delivered on flexible fiber. It can be integrated into the SmartXide² at any time as an optional upgrade.
Holographic lenses and mirrors, a single-ring focus system with focal point memory, and four functions on one microswitch joystick. Compatible with all surgical microscopes.
Laser beam movement in 100 millionths of a second with minimum dwell time, across scanning shapes of up to 6.3 mm for tissue cutting and ablation.
Different focusing lenses, spacers and mirrors from 1.5″ to 8″ EFL plus collimated, each with a dedicated air inlet and integrated smoke extraction at the tip.
Retrievable database protocols set the energy needed to make the plate hole with a single pulse, by scanner-assisted CO₂ laser or by diode fiber.
The SmartXide² ENT pairs an RF-excited CO₂ laser on a 7-mirror articulated arm with an optional 980 nm diode module on flexible fiber. Both are driven from the same 15.6″ touchscreen.

Diode Laser Module
An additional wavelength (980 nm) to expand the range of available procedures. Flexible fiber optics reach internal anatomy the articulated arm cannot, and the module can be added to the SmartXide² at any time.
Connectable with
Pulse Shape Design generates variable peak pulses with different structure, duration and power, so the source adapts to the clinical condition rather than the other way round.
Single-pulse comparison
Single-pulse continuous-supply excited CO₂ laser. The pulse spikes, then falls back below the ablation threshold for most of its length.
Single-pulse radiofrequency excited CO₂ laser. Power is reached almost immediately and held above the threshold for the whole pulse.
Radiofrequency-excited CO₂ laser sources produce greater energy above the ablation threshold compared to continuous-supply excited CO₂ lasers, and at comparable pulse length. Figures redrawn from the manufacturer’s technical literature; shapes are illustrative of the emission behaviour, not measured traces.
Massive energy in microseconds. Perfect ablation without tissue carbonisation, which is what makes it the working mode for ENT microsurgery.
No acoustic effect during emission, which is the property that makes it suitable for the “ONE SHOT” stapedotomy technique.
The SmartXide² RF-excited CO₂ laser source offers high power and speed of action. PSD® (Pulse Shape Design) uses both, generating variable peak pulses with different structure, duration and power to adapt to the various clinical conditions.
U-Pulse is the perfect pulse for ENT microsurgery: a massive energy is supplied in microseconds, ensuring a perfect ablation without tissue carbonisation. “Real CW” has no acoustic effect and is therefore suitable for the “ONE SHOT” stapedotomy technique. Both are the modes most commonly used in this kind of surgery.
Emission modes
Bars are scaled to the 80 W maximum of the C80 chassis. SP, DP and HP envelopes are identical across all four models; only CW and UP differ between the 60 W and 80 W configurations. DEKA’s technical sheet lists all five modes by code and names only CW and U-Pulse in prose.
DEKA scan-assisted ENT laser microsurgery, built around four things the surgeon should never have to think about: control, field, focus and setup.
DEKA scan-assisted ENT laser microsurgery
Operate without ever moving your eyes from the microscope.
Four functions on the exclusive microswitch joystick: scanning shape rotation, ablation figure dimension, Scan-ON/Scan-OFF and laser beam centering.
Mechanical control of the working area.
Precisely confines the laser beam within the operating field. Easy and safe.
Hybrid technology focusing system.
Holographic lens and high-reflectance mirrors, with a single-ring focus/defocus system and focal point memory. High depth focus, with exact correspondence between the guide light and the CO₂ laser.
Fast connections and internal wiring.
Easy Control
Four functions sit under one thumb on the exclusive microswitch joystick. Shape rotation runs step-by-step or fast, figure size and beam centring are adjusted live, and the scanner is switched on and off without breaking the surgeon’s line of sight.
Ultra-fast laser beam movement — 100 millionths of a second, minimum dwell time — across high-precision scanning shapes of up to 6.3 mm for tissue cutting and ablation.

Up to a few years ago, “ONE SHOT” laser stapedotomy had to be performed only with micromanipulators and scanning systems. Today the same minimally-invasive technique can be performed with a fiber delivered diode laser with high power and low time of emission.
Dedicated retrievable database protocols set the laser energy necessary to make the plate hole with a single pulse, ensuring operative simplicity, safety and precision.

Published accounts from ENT surgeons using the CO₂ and diode platforms in laryngeal and otologic practice.
I’ve been using diode laser for stapedotomies since the end of the 1990s. It’s very easy to use, safe and makes the surgical procedure faster. I started with 940 nm and switched to 980 nm, which I prefer. The main characteristic of 980 nm is that it’s partially absorbed by water, therefore the perilymph, although not its main target, acts as a backstop and therefore does not produce any heating of the inner ear. The main characteristic of the “One Shot” stapedotomy is the supply of highly concentrated energy on the bone in a brief exposure time, thus preventing temperature increase of surrounding tissues.
Since 2007, with this technique, I have performed hundreds of procedures and most patients have a long follow-up with good results. The “One Shot” diode laser technique significantly simplifies the surgical procedure, especially when compared to traditional techniques such as the use of manual perforation and microdrill which are not selective and precise on the delicate structures of the inner ear.

The DEKA CO₂ laser, with progressive scanning technology, makes surgery on delicate tissues, like vocal cords, easier and safer. This is a wonderful tool for selective reconstruction procedures of the airways, with a series of significant advantages that go from ablation depth control, to reduced thermal damage, to lower dependence on the imprecise movements of the surgeon’s hand.

Thanks to the precision and replicability that only scan-assisted CO₂ laser microsurgery can offer, the new HiScan Surgical scan system, along with the Easyspot Hybrid micromanipulator, has significantly simplified the performance of delicate and complex surgical procedures such as transoral larynx surgery and laser stapedotomy.
