Association between Tumor Microbiome and Hypoxia across Anatomic Subsites of Head and Neck Cancers.

Purpose/Objective(s): Microbiome has been shown to affect tumorigenesis by promoting inflammation. However, the association between the upper aerodigestive microbiome and head and neck squamous cell carcinoma (HNSCC) is not well established. Hypoxia is a modifiable factor associated with poor radiation response.

The use of medical modeling in microvascular free tissue transfer reconstruction with osseointegrated implantation in complex midface defects.

Osseointegrated implants in conjunction with microvascular free tissue transfer reconstruction has been increasingly adopted in our head and neck cancer population. However, the majority of the literature on dental rehabilitation in free flaps have been for mandibular defects. Midface and maxillectomy defects are challenging defects for reconstruction.
