Histologic effect of the potassium-titanyl phosphorous laser on laryngeal papilloma.

ABSTRACT:

Objectives

Tissue effects occurring with potassium-titanyl phosphorous (KTP) laser treatment are difficult to quantify due to the multiple variables that affect not only the fluence (energy delivered) but also the laser-tissue interaction. This histopathologic analysis of recurrent respiratory papilloma (RRP) removed after treatment with KTP laser therapy permits correlation of histologic effect with method of laser treatment.

Methods

The histopathology of RRP resected specimens in a single patient was compared following treatment with KTP laser in contact and non-contact modes as documented with intraoperative photography and video imaging.

Results

Epithelial-sparing injury selective to the microvasculature was identified on histopathologic assessment of a specimen t
