Unique Techniques Utilizing Rib Grafts for Mandibular Reconstruction in the Pediatric Population

Area of Science:

• Pediatric surgery
• Oral and maxillofacial surgery
• Regenerative medicine

Background:

• Pediatric mandibular reconstruction demands grafts with sufficient height and stability for dental implants.
• Existing techniques like double barreling and mandibular distraction osteogenesis (MDO) are typically used with fibular grafts.
• Rib grafts present lower donor site morbidity and adequate defect coverage in children.

Purpose of the Study:

• To evaluate the use of autogenous rib grafts in pediatric mandibular reconstruction.
• To assess the feasibility of augmenting rib grafts with double barreling or MDO for improved outcomes.
• To determine the utility of rib grafts for supporting dental implant placement in pediatric patients.

Main Methods:

• Three pediatric patients underwent mandibular resection and reconstruction using rib grafts.
• One patient received a single rib graft followed by vertical rib distraction.
• Two patients underwent reconstruction with a double-barreled rib technique (horizontal and vertical configurations).

Main Results:

• Three pediatric patients (average age 11) with mandibular lesions underwent reconstruction with rib grafts.
• One graft was removed due to wound complications; the other two had uneventful recoveries.
• Osseointegration for dental implants was achieved in one patient, with planning in another; no donor-site complications occurred.

Conclusions:

• Autogenous rib grafts are a viable and adaptable option for pediatric mandibular reconstruction.
• Augmenting rib grafts with MDO or double barreling enhances their height and stability.
• This approach facilitates successful dental implant placement and oral rehabilitation in pediatric patients.
