Killions incision is used for?
a) Septoplasty
b) SMR
c) Proof puncture
d) Modified radical mastoidectomy
Correct Answer - A
Ans. is ‘a’ i.e., Septoplasty
Technique of septoplasty

  1. Infiltrate the septum with 1% lignocaine with adrenaline
    1:100,000.
  2. In cases of deviated septum, make a slightly curvilinear incision,
    2-3 mm above the caudal end of septal cartilage on the concave
    side (Killian’s incision). In case of caudal dislocation, a transfixion or
    hemitrans fixion (Freer’s) incision is made.
  3. Raise mucoperichondrial/mucoperiosteal flap on one side only.
  4. Separate septal cartilage from the vomer and ethmoid plate and
    raise mucoperiosteal flap on the opposite side of septum.
  5. Remove maxillary crest to realign the septal cartilage.
  6. Correct the bony septum by removing the deformed parts.
    Deformed septal cartilage is corrected by various methods, such as :
    Scoring on the concave side
    Cross-hatching or morselizing
    Shaving
    Wedge excision
    Further manipulations like realignment of nasal spine, separation of
    septal cartilage from upper lateral cartilages, implantation of
    cartilage strip in the columella or the dorsum of nose may be
    required.
  7. Trans-septal sutures are put to coapt mucoperichondrial flaps.
  8. Nasal pack
