su~~ary & conclusion
The carbon dioxide laser provides a safe and efficacious
technique for treatment of benign laryngeal lesions, provided
that certain precautions are taken.
It is possible by means of C02 laser to remove extensive
papillomatosis without the risk of postoperative oedema and
also without tracheostomy, although it is not possible to cure
the disease completely.
Polyps and cysts of the cord are easily vaporized without
damage to the healthy tissues and with rapid wound healinq F.lnc1
voice improvement.
Carbon dioxide laser provides a good method for treatrnr-nt
of subglottic stenosis without tracheostomy, results of CO2
laser excision of subglottic stenosis is not 50 favorable cHId
further studies are needed specially for those due to
laryngoscleroma.
The specific advantages of C02 laser surgery includes:
Tissue destruction is precise, immediate and bloodless.
protection of the surrounded structures with preservation
of anatomy and functions.

Airway preservation without tracheostomy.
Tissue manipulation is unnecessary and the absence of
instruments means visual access to the operative field.
Rapid healing without stricture formation.
Possibility of repeated surgery without or with minimal
trauma.
The major hazard of laser is misdirection of the lasp,r
beam either directly or reflection from instrument as it may
strike unprotected area of patient, member of operating room
personnel or unprotected anaesthetic tube carrying oxygPP
causing ignition of the tube.
In conclusion, C02 laser surgery is very helpful in thp
treatment of papillomatosis, polyps, cysts of the vocal cord as
well as subglottic stenosis. The use of C02 laser is
recommended whenever possible for these cases.
