Abstract
BackgroundPedicled buccal fat pad (PBFP) has been used for the reconstruction of small-sized maxillary defects but cannot be used without hard tissue support on the defect larger than 4 cm × 4 cm × 3 cm.Case presentationA 64-year-old man had a history of squamous cell carcinoma of the left maxilla. After removal of the posterior maxilla, a complex bone defect (size, 5 cm × 4 cm × 3 cm) was immediately reconstructed using PBFP combined with a titanium mesh. A pinpoint fistula was found in the left palatal region 1 month after the surgery and was treated with a palatal sliding flap. There were no further complications during the follow-up.ConclusionThe present technique demonstrated that PBFP combined with a titanium mesh could be used for the reconstruction of complex maxillary defect (size, 5 cm × 4 cm × 3 cm) without additional bone graft.

BackgroundPedicled buccal fat pad graft (PBFP) is one of the procedures used for the reconstruction of maxillary defects such as oroantral fistula, cleft palate, medication-related jaw bone necrosis, and defects formed after cysts or tumors removal [1]

Summary
Pedicled buccal fat pad graft (PBFP) is one of the procedures used for the reconstruction of maxillary defects such as oroantral fistula, cleft palate, medication-related jaw bone necrosis, and defects formed after cysts or tumors removal [1]. Maxillary defect (size, 5cm × 4cm × 3cm) was successfully reconstructed using a PBFP combined with a titanium mesh without bone graft. On September 8, 2020, the patient complained of leakage of fluid into the nasal cavity and one pinpoint fistula was found (1.5 mm in size) in the border between the regenerated mucosa and resection margin It was located in the distal region of the left first premolar area. Adjuvant therapies for tumor such as chemotherapy or radiotherapy were not performed after the surgeries
