Figure A and B are images during active acute laryngitis. Note inflamed supraglottic mucosa with very oedematous arytenoids and tight glottic chink (worse during inspiration).
Figure C and D are images upon resolution of acute laryngitis (1 week apart).

Another example of laser cordectomy; before and after surgery respectively.
At completion of surgery. Postoperative Day 1.
Bipolar radiofrequency device was used for this case
set at 5W cut/coagulation mode with arytenoid cartilage preserved.
Remnant of right arytenoid cartilage (arrow) after its vocal process removed.
Glottic view after the operated side healed [right side].
Immediate post-operative view.

Fibrin exudate formation is a normal phenomena seen after CO2-laser cordectomy performed. It occurs as part of healing process until epithelialization is completed.
Well-formed left posterior cordectomy with partial arytenoidectomy complicated by small granulation tissue. Trial of proton-pump inhibitor should be given and response monitored closely. Non-responsive and obstructing granuloma
needs to be removed surgically.
