ALT Rescue Flap With Iliac Crest Bone Graft and Spanning Plate for Mandibular ORN

The Laryngoscope, Volume 136, Issue 6, Page 2573-2580, June 2026.
In select patients with focal full‐thickness mandibular ORN defects, the use of ALTFL in conjunction with ICBG and a spanning reconstructive plate appears to offer clinical and radiographic arrest of ORN. This technique has considerably lower morbidity than osteocutaneous reconstruction, with abbreviated hospital stays, a low complication rate, and no ...
