The aim of this case series, is to describe our surgical technique for reconstructing benign mandibular neoplasms using BMAC – a less invasive approach than traditional iliac crest bone graft harvest.
BMAC was used in combination with mineralized freeze-dried allograft, platelet rich plasma (PRP) & bone morphogenic protein (rhBMP-2) to reconstruct the hard tissue lost secondary to the ablative tumor resection.
- 10 patients included in the retrospective case series were treated between 2014 and 2017 by 3 surgeons.
- Mean age - 44 years (range - 19 to 77 years). BMAC was obtained from the anterior iliac crest (AIC).
- When appropriate, a custom milled mandibular reconstruction plate was placed.
- Maxillofacial pathology included benign neoplasms such as Ameloblastoma, Cavernous Hemangioma, Central Giant Cell Granuloma (CGCG), Dentigerous Cyst & Keratocystic Odontogenic Tumor (KOT).
Treatment of Obstructive Sleep Apnea with Maxillo-mandibular Advancement Surgery: Evaluation and Predictors of Success
Daniel Taub, DMD, MD; Michael Courtney, DMD, MD; and Karl Doghramji, MD
Obstructive sleep apnea (OSA) is a well-recognized disease entity affecting approximately 2% to 4% of the population. Maxillomandibular advancement (MMA) surgery is a highly successful surgical alternative to poorly tolerated CPAP therapy and achieves a success rate of 89% in the current literature. Our present study evaluates the effectiveness of MMA surgery in the treatment of patients with moderate to severe OSA based on Shers criteria of 50% reduction in AHI and AHI < 20. Radiographic and clinical treatment variables were evaluated in determining predictors of success for MMA in individuals with OSA.
