Laser Ear Surgery - OmniGuide BeamPath®

Physicians at the Dallas Ear Institute utilize the latest laser technology to operate on the ear and skull base. Laser surgery involves cutting or treating tissue with an intense, concentrated beam of light. Laser beams vaporize target tissue by evaporating the water inside its cells. Due to its unique physical characteristics, CO2 laser energy is used by surgeons because it provides high precision and control during surgery.

CO2 laser offers surgeons a no-touch dissection tool, ideal for use around the delicate structures of the middle ear. The Dallas Ear Institute physicians utilize this tool in the treatment of many middle ear diseases, including otosclerosis and cholesteatoma, to allow precise and delicate treatment of the underlying problem. By using the laser, your physician is able to more safely treat the underlying problem, enhancing hearing results and surgical outcomes.

In stapedectomy surgery for otosclerosis, the laser is used to remove the fixed stapes bone with minimal trauma to surrounding structures. In addition, the technology is used to make an opening into the inner ear with precision that only the laser can afford. By decreasing manipulation of the hearing bones, outcomes after surgery may be improved. In addition, the handheld CO2 laser technology can be utilized in patients with chronic ear disease. In these patients, the laser allows removal of diseased tissue with no-touch dissection and the potential for decreased recurrence of disease.

The combined cutting, ablation, and microvascular coagulation capabilities of the handheld CO2 laser system allows for efficient yet delicate, layer-by-layer removal of diseased tissue. Of critical importance, the no-touch dissection that is afforded by the laser technology can be performed without vibrational trauma to the hearing bones within the inner ear, making this a safer procedure. The Dallas Ear Institute physicians often utilize this cutting-edge technology to treat patients with ear disease.


Co2 - Laser Assisted Stapes Surgery

The BeamPath OTO-S fiber’s streamlined geometry enables superior visualization in the confined space of the middle ear. The BeamPath OTO-S is designed for Primary and Revision Stapes surgery and is used to precisely resect the stapes tendon and crus and to safely form a rosette in the footplate. The superficial absorption of CO2 laser energy in the perilymph may help to minimize the risk of damage to underlying middle and inner ear structures. Thousands of CLASS procedures have been performed using the BeamPath OTO system. These procedures include:

  • Primary Stapedectomy/Stapedotomy
  • Revision Stapedectomy/Stapedotomy

Large clinical study reports superior outcomes using the CO2 laser for primary stapes surgery when compared to the KTP laser.

97% of patients treated with the CO2 laser had post-op ABG ≤ 10dB compared with 92% of patients treated with the KTP laser.
Frequency-specific ABG outcomes at 4kHz, showed statistically significant improvement with the CO2 laser compared to the KTP laser.

CLEAR – CO2 Laser Enabled Ablation & Resection

The BeamPath OTO System offers surgeons a no-touch dissection tool, ideal for use around the delicate structures of the middle ear. The combined cutting, ablation, and microvascular coagulation capabilities of the BeamPath OTO system allow for efficient yet delicate, layer-by-layer removal of diseased tissue. No-touch dissection of diseased tissue, often encountered during chronic ear surgery, can be performed without vibrational trauma to the adjacent ossicular chain. The CLEAR surgical technique is used for removal of diseased tissue during:

  • Revision procedures (e.g. Tympanoplasty, Mastoidectomy)
  • Tympanoplasty & Mastoidectomy
  • Tumor Removal (Glomus Tympanicum, Acoustic Neuroma)
  • Ossicular Chain Reconstruction

The handheld BeamPath OTO allows CO2 laser energy to be used as never before, for:

  • Adhesion ablation
  • Scar tissue dissection
  • Cholesteatoma removal
  • Debulking and coagulation of vascular tumors

About CO2 Laser

Why Surgery with the CO2 Laser?

The term “laser surgery” covers a wide range of lasers that interact very differently with tissue. The “color” or wavelength of a laser determines how well it is absorbed by water, pigmented tissue and blood (hemoglobin).

As the chart illustrates, CO2 lasers have the shallowest penetration in water (the main component of living cells) among commonly-used surgical lasers. This ensures minimal penetration depth into tissues. How does this lead to a better surgical outcome for you? Better absorption in tissue means that the energy delivered by the CO2 laser spreads through tissue in a limited manner. This, in turn, allows surgical procedures to be performed precisely, with very little damage to surrounding healthy tissue.

Though CO2 lasers offer significant benefits over other surgical techniques (refer clinical publications), the absorbent nature of CO2 laser energy means that it is not only well absorbed in soft tissue, it is also well absorbed in all known transparent materials, including glass.

Because of this limitation, CO2 laser energy could not be transmitted through flexible fibers for three decades. Until the launch of the BeamPath fiber system, CO2 laser energy was delivered using a bulky arrangement of arms and mirrors in the line of sight of a surgeon. This unwieldy setup prevented surgeons from performing several forms of minimally invasive surgery using the CO2 laser energy. For example, by using the BeamPath technology, surgeons have been able to resect invasive throat cancers that before could only be accessed and removed during radical, lengthy, operations. The ability to perform surgery in a minimally invasive fashion directly benefits you by reducing your time in the operating room as well as hastening your recovery.

OmniGuide is the first and only manufacturer of unique fibers that can deliver CO2 laser energy for minimally invasive surgery. The technology, developed at MIT, was published in two of the world’s most prominent scientific journals, Nature and Science.
OmniGuide is committed to continuously enhancing the quality of care you receive from your surgeon. OmniGuide aims to improve your surgical outcome by offering your surgeon a no-touch, precision microsurgical instrument – the BeamPath flexible CO2 laser scalpel.

OmniGuide BeamPath® OTO

Surgeons use the BeamPath OTO system because it delivers precise CO2 laser energy through a flexible fiber. The BeamPath OTO fiber allows the surgeon to operate with controlled precision and safely perform the surgical procedure while preserving the healthy structures of the middle and inner ear. The flexibility of the hand-held BeamPath OTO fiber allows surgeons to manipulate CO2 laser energy and treat a variety middle and inner ear conditions.

The BeamPath system can be used for the following surgical procedures:

  • Stapedotomy
  • Revision stapedotomy
  • Ossicular chain reconstruction
  • Chronic ear surgery
  • Glomus tumor
  • Acoustic neuroma
  • Cochlear implant

The BeamPath fiber system from OmniGuide enables surgeons to use CO2 laser energy for performing safe and controlled precision-microsurgery.

For decades, lasers have provided the only no touch surgical tool available to surgeons. Of these, CO2 lasers have always been considered the most safe and precise. CO2 energy is readily absorbed in water (the main component of living cells) leading to minimal thermal spread and collateral tissue injury. OmniGuide’s novel technology, the BeamPath™ fiber system, enables for the first time flexible delivery of CO2 laser energy to the human body, even in deep holes and previously tough-to-get-to regions. Placing control of the optical scalpel at the fingertips of the surgeon, this precision tool empowers surgeons to achieve higher level of surgical efficacy and patient comfort.

OmniGuide’s BeamPath fiber combines the capability of precise dissection, ablation and microvascular coagulation, all in a single tool. Surgeons accustomed to previous “line-of-sight” CO2 lasers will now be able to access previous inaccessible regions. Those who have not used the CO2 laser in the past will witness the myriad advantages this flexible no-touch precision microsurgical tool has to offer, especially in and around critical structures. Surgeon control over tissue interaction is achieved by altering parameters such as power level and distance from the tissue, ensuring the necessary effect precisely as and when desired.

To date, the OmniGuide fiber system has been used in more than 20,000 procedures across surgical specialties spanning neurosurgery and spine oncology, otology, head & neck surgeries, laryngology & airway procedures, gynecology, pulmonology and gastroenterology. With an ever-growing surgeon base who have realized the power of flexible no-touch, CO2 based precision microsurgery, OmniGuide’s BeamPath™ fiber system is helping surgeons redefine the boundaries of surgical practice and helping patients experience the benefits of minimally invasive, no touch surgery.
