SMR vs Septoplasty

 

ENT Surgery: SMR vs. Septoplasty

High-Yield NEET PG Comparison Table

For board examinations, distinguishing between the Submucous Resection (SMR) and Septoplasty is critical for surgical management questions.

1. Head-to-Head Comparison

Feature SMR (Submucous Resection) Septoplasty
Philosophy Radical/Resective Conservative/Reconstructive
Cartilage Extensive removal Preserved (repositioned)
Complication Higher risk of perforation Lower risk
Age Limit Not for children Preferred for children

2. NEET PG High-Yield Pearls

  • The “L-Strut”: Preservation of at least 1–1.5 cm of cartilage along the dorsal and caudal aspect is mandatory in septoplasty to prevent saddle nose deformity.
  • Incision Type: SMR classically utilizes Killian’s incision, whereas septoplasty often employs a hemitransfixion incision.
  • Flap Handling: Both procedures rely on the elevation of mucoperichondrial and mucoperiosteal flaps. Perforation risk is significantly higher if bilateral opposing incisions are made.
  • Indications: While septoplasty is the modern standard for simple DNS, SMR is historically described for severe deformities or revision cases where structural support may be compromised differently.
