980nm Diode Laser Used In ENT Surgery
The lightweight, portable 980-nm wavelength Berylas Diode laser
with a fiber optic delivery system is being used widely the field
of otolaryngology.The laser transmits radiation via a flexible
quartz fiber optic cable that can be used with a set of intra
nasal, micro laryngeal hand pieces. These hand pieces allow for
optimal laser focusing.
Light at its particular wavelength is absorbed by tissues
relatively independent of tissue type. Tissue response at this
wavelength is determined by the absorption of water as well as by
absorption of endogenous components such as hemoglobin and melanin.
As a result, the diode laser has a large (up to 10 mm) penetration
depth in biologic tissue, which makes it ideal for photo
coagulation. By contrast, the Co2 laser has a very shallow
penetration depth and thus is best used for tissue vaporization.
The Berylas 15watts flexible fiber delivery system is compatible
with hollow ENT handpiece allows for coaxial vision, and is ideally
suited for intranasal, oral and micro laryngeal use.

Berylas laser system is housed in a portable case and light weight
so it can be easily transported between the operating rooms. The
length of set-up time is generally less than 5 minutes, and no
warm-up period is necessary.
1. It can be used in contact mode, in which the tip of the fiber is
placed directly on the surface of the tissue. This mode is
effective for both photocoagulation and vaporization of tissue,
depending on the power density. At the low- or mid-power range,
coagulation occurs; at a higher level, vaporization occurs.
2. The laser can be used in near-contact mode, in which the tip of
the fiber remains several millimeters apart from the tissue. This
mode is largely used for tissue photo coagulation.
3. The laser can be used for interstitial laser-induced
thermotherapy, a minimally invasive method of treating both benign
and malignant tumors. The laser is placed through puncture holes in
the skin, and its energy is absorbed by local tissues. This
hyperthermic state causes either immediate or delayed tissue
necrosis via coagulation.
4. In the clinic most cases can be done after administering a
topical anesthetic and a decongestant spray to the nasal cavity,
but micro laryngeal surgery needs General anesthesia with special
fleximetalic tube to prevent fire hazard.
