RECONSTRUCTION
• Surgical removal of oral tumorOsseous defect
• Range of defect i) loss of alveolar bone ii) loss of major portion of jaw
surgical reconstruction
• Loss of alveolar bone– need for osseous base for bridge/partial or complete denture
• Ridge augmentation to form an osseous base
MAXILLARY DEFECT
• Continuation of nasal cavity or maxillary sinuses with oral cavity
• Difficulty in speaking,eating,drinking
Surgical option• Less extensive defect:• Closure with available soft tissues of buccal
and palatal mucosa
TIMING OF RECONSTRUCTION
• Immediate(at the time of surgical removal)• Delayed • Benign tumors resection—immediate
reconstruction• Malignant tumors----delayed reconstruction
Delayed reconstruction after removal of malignant tumor
REASONS• 1) To prevent bone graft resorption if post op
radiotherpay planned• 2)more soft tissue required • 3) recurrence
Delayed reconstruction after removal of benign tumor
• Presence of simultaneous intraoral and extraoral defects
Maintenance of residual fragments
• Delayed reconstruction--- maintenance of residual fragments :
• Options i) external pin fixation ii) splints iii)IMF iv) recon plates
IMMEDIATE RECONSTRUCTION
ADVANTAGES• Viable option• Reqiring single surgical procedure• Early return to function• Minimal compromise to facial esthetics DISADVANTAGESLOSS OF GRAFT DUE TO INFECTION
