Description

Derkay et al developed a staging system for patients with recurrent respiratory papillomatosis (RPP) which is based on 2 scores - one clinical and one anatomical. The combined score can be used to evaluate the patient initially and to monitor the response to therapy.


Parameters of the clinical score:

(1) voice

(2) stridor

(3) urgency of intervention

(4) respiratory distress

total clinical score =

= SUM(points for all 4 parameters)

 

Interpretation:

• minimum clinical score: 0

• maximum clinical score: 11

• The higher the clinical score the more severe the clinical status of the patient.
