MRONJ and Polynucleotides-Hyaluronic Acid Hydrogel (Regenfast®)

Several circumstances or conditions, such as wound extension or disease, can affect the hard and soft tissue healing after surgical treatment of MRONJ. Supportive therapies are therefore needed to help tissues wound healing. The primary objective of this pilot clinical case series is to evaluate the post-operative wound healing in a group of patients undergoing surgical therapy for MRONJ with intraoperative application of a gel based on polynucleotides and hyaluronic acid (PN+HA) (Regenfast®)

Inclusion criteria

  • Patients older than 18 years
  • Provided informed consent
  • MRONJ stage 1 and stage 2 diagnosis, in accordance to SICMF-SIPMO classification
  • Need to undergo surgical treatment of MRONJ

Exclusion criteria

Treatment and study plan

MRONJ resection plus PN+HA

Device

Surgical management will be performed by reflecting a full-thick flap to expose the entire affected area, followed by removal of necrotic bone until a vital, unaffected bony margin will be obtained. After bone resection, the PN+HA (Regenfast®) will be applied on the residual bone surface. Wound management will be done via primary closure.

Primary outcomes

  1. Clinical wound healing (modified Landry Healing Index)

    Time frame: 7 days after surgical treatment

    The clinical wound healing of the site will be assessed throughout the modified Landry Healing Index

  2. Clinical wound healing (modified Landry Healing Index)

    Time frame: 14 days after surgical treatment

    The clinical wound healing of the site will be assessed throughout the modified Landry Healing Index

  3. Clinical wound healing (modified Landry Healing Index)

    Time frame: 21 days after surgical treatment

    The clinical wound healing of the site will be assessed throughout the modified Landry Healing Index

  4. Clinical wound healing (modified Landry Healing Index)

    Time frame: 3 months after surgical treatment

    The clinical wound healing of the site will be assessed throughout the modified Landry Healing Index

  5. Clinical wound healing (modified Landry Healing Index)

    Time frame: 6 months after surgical treatment

    The clinical wound healing of the site will be assessed throughout the modified Landry Healing Index

  6. Clinical wound healing (modified Landry Healing Index)

    Time frame: 12 months after surgical treatment

    The clinical wound healing of the site will be assessed throughout the modified Landry Healing Index
