Background: 
 Extensive maxillary tumor resections can present significant reconstructive challenges. Tumors requiring near-total bilateral maxillectomy necessitate reconstruction of significant midface structural support and large soft tissue volume for dead space obliteration to restore form and function. 
 
Learning Objectives: 
 To date, there have been few descriptions of successful reconstructive techniques following complex bilateral maxillectomy. 
 
Study Objective:  
 We propose a novel reconstructive approach utilizing chimeric vascularized serratus-rib and scapular tip with and without latissimus dorsi. 
 
Design Type:  
 Novel Technique, Case Series 
 
 
Methods:  
 Three patients at a single institution who underwent near-total bilateral maxillectomy (unilateral total and contralateral infrastructural) for cancer resection and reconstruction with vascularized serratus-rib and scapular tip with and without latissimus dorsi in 2023 and early 2024 were included. The total maxillectomy side used a carved scapular tip to reconstruct the orbital rim, the zygomatic process, and the alveolar ridge, with a custom orbital floor implant. The contralateral, subtotal defect was reconstructed with a vascularized serratus-rib flap, utilizing the serratus to reconstruct the palate and fill the midface soft-tissue defect. In cases of orbital exenteration, latissimus dorsi was elevated with the scapular tip and used to fill the orbital cavity. 
 
 
Results:  
 Patients were followed for at least 7 months post-reconstruction without flap failures. All hardware remained intact with appropriate facial contouring. One patient died 8 months post-reconstruction due to complications of pneumonia. Another’s recovery was complicated by recurrent pleural effusion requiring temporary chest tube placement. 
 
 
Conclusion:  
 We propose this reconstructive technique as a viable option for bilateral maxillectomy patients.
