Killian's incision = curvilinear septal incision for septoplasty.

- Septoplasty
- Submucous resection (SMR)
- Proof puncture
- Modified radical mastoidectomy

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Killian's incision is a specific nasal septal incision. In septoplasty for a deviated nasal septum, a slightly curvilinear incision is made 2 to 3 mm above the caudal end of the septal cartilage on the concave side - this is Killian's incision. This makes option (a) correct.
Step 2: The incision allows elevation of the mucoperichondrial flap so the deviated septal cartilage and bone can be conservatively corrected and realigned while preserving the framework.
Step 3: In classic submucous resection (SMR), a Freer's incision (transfixion or hemitransfixion) is more typically described, and the goal there is removal rather than conservative preservation, so option (b) is not the best match for Killian's incision.
Step 4: Proof puncture is an antral wash done through the inferior meatus, and modified radical mastoidectomy is a postaural ear operation. Neither uses a septal incision, so options (c) and (d) are wrong.
