title: Reverse facial artery-submental artery mandibular osteomuscular flap for the reconstruction of maxillary defects following the removal of benign tumors.
abstract: BACKGROUND
  Functional and aesthetic restoration in maxillary reconstruction remains a challenge. Although many free flap procedures have become popular in maxillary reconstruction, these microsurgical methods have certain limitations and risks. This study assessed the reliability of the reverse facial artery-submental artery mandibular osteomuscular flap for reconstructing maxillary defects.
  
  
  METHODS
  Eight maxillary defects following benign tumor ablation were repaired with reverse facial artery-submental artery mandibular osteomuscular flaps. The patients ranged in age from 16 to 33 years; 5 were male and 3 were female. Maxillary odontogenic myxoma was present in 3 cases, maxillary fibrous dysplasia and ameloblastoma in 2 cases each, and chondromyxoid fibroma in 1 case. The defects were classified as class 2a.
  
  
  RESULTS
  Primary reconstruction of the maxilla was carried out using a pedicled mandibular osteomuscular flap. No flap failures occurred. Dental reconstruction was successful in all patients. Proper aesthetics and complete functionality were obtained, and there were no donor-site problems. The patients were followed for 12 to 24 months, with an average of 18.6 months, and no recurrence was encountered.
  
  
  CONCLUSIONS
  The reverse facial artery-submental artery mandibular osteomuscular flap is safe, quick, and simple to elevate. The flap can be used reliably for reconstructing maxillary defects.
