Otologic Applications of the Laser
Users should be aware of general laser warnings, precautions, and adverse
effects listed in “General Information” in this chapter.
Indications
•
The laser is indicated in procedures where color-specific
absorption, small spot size, and high power densities are required.
The laser beam may be used to photocoagulate, vaporize, or cut
tissue by utilizing the appropriate beam delivery accessory and
varying spot size, output power, and pulse duration.
•
The laser has been shown to achieve satisfactory results in
stapedotomy, stapedectomy, tympanoplasty with fascia graft
1
,
myringotomies
2
, control of bleeding, lysis of adhesions, and soft
tissue adhesion (“spot welding”).

Uses
•
The laser is indicated in both micro- and macro-otologic
procedures. The selective absorption of the laser wavelength by
color permits the surgeon to work on closely-approximated soft
tissue which is colored red, but the laser is reflected and/or
transmitted by adjacent non-red tissue.
•
The laser may be used for procedures done in the hospital for in-
patient or out-patient procedures. The use of the laser is not a
contributing factor in deciding if a procedure is done on an in- or
an out-patient basis.
Contraindications
•
One investigator reported that the laser was not indicated in the
removal or vaporization of cortical bone or dense bone as found in
obliterative otosclerosis.

•
Uninflamed mastoid cases, such as endolymphatic sac surgery and
cochlear implants do not benefit from the laser.
