When is item code 52621 (Floor of Mouth Lowering) typically used?

The need for floor of mouth lowering (e.g., Obwegeser procedure) arises when a patient has a high or tight floor of mouth—often from congenital issues, trauma, or surgery—causing denture instability, speech difficulties, or swallowing problems, requiring surgical lowering under anesthesia with assistance, including muscle excision or grafting, for unilateral correction. This is indicated for significant floor issues, critical where oral function is impaired in the maxillofacial region.

Specific scenarios include:

  • Denture issues: High floor prevents stable wear.
  • Trauma: Scarring raises the floor, needing lowering.
  • Congenital: Tightness affects speech or swallowing.
  • Function: Improves oral mechanics.

For example, a patient with a tight mandibular floor might need this for denture fit, with grafting for depth. In aged care, an elderly patient could benefit for swallowing, given frailty. By lowering the floor, this service enhances function, supports dentures, and improves comfort, making it a specialized maxillofacial solution.

Benefits to the patient

Surgeons lowering the patient’s floor of mouth (e.g., Obwegeser procedure) unilaterally under anesthesia with assistance provide functional benefits. A key advantage is enhancing denture fit. This procedure adjusts the patient’s oral floor, improving prosthetic placement—essential for 'floor of mouth surgery benefits.' It also improves swallowing by increasing space, aiding the patient’s eating ability. Furthermore, it restores oral function by supporting better anatomy, enhancing the patient’s comfort. For surgeons researching 'Obwegeser procedure advantages,' this assisted service ensures patients benefit from fit enhancement, swallowing improvement, and functional restoration, offering a targeted fix for oral floor issues.

Recovery considerations

Recovery of 3-4 weeks with swelling and soft diet; hospital stay likely.
