Oral Surgery · single question

A patient on bisphosphonate therapy presents with osteonecrosis of the jaw and purulent drainage following a recent extraction. What is a key principle of management?

  1. Conservative management, with surgical debridement reserved for more advanced or refractory cases, per current MRONJ staging guidance
  2. Immediate aggressive surgical resection in all cases regardless of severity
  3. No treatment is ever indicated for established MRONJ
  4. Discontinuing the bisphosphonate is guaranteed to fully resolve the condition quickly
Show answer and explanation

Correct answer: A. Conservative management, with surgical debridement reserved for more advanced or refractory cases, per current MRONJ staging guidance

Per current AAOMS position paper guidance on medication-related osteonecrosis of the jaw (MRONJ), management is generally staged based on severity — early, less severe presentations are managed conservatively (antimicrobial mouth rinses, systemic antibiotics for active infection, minimizing further surgical/bone trauma), while more advanced, refractory, or extensively necrotic cases may require surgical debridement, ideally in coordination with an oral and maxillofacial surgeon experienced in MRONJ management.
