Reconstructions of the maxillary defect after tumor resection are challenging surgeries. Maxillary reconstructions are done using obturators, locoregional flaps and free tissue transfers. Free flap options available for maxillary reconstruction are radial forearm, anterolateral thigh free flap, free fibular osteocutaneous flap, rectus abdominis myocutaneous flap, scapular, and iliac crest osteomyocutanous free flap etc. This is a single institutional observational study conducted at a tertiary cancer centre in North East India from May 2018 to April 2019. All the reconstructions are done with free tissue transfer. Post-operative outcome was assessed with University of Washington Quality of Life Questionnaire (UW-QOL v4.1). Data was collected from patient records and hospital online reporting system. All data were analysed using SPSS (statistical package for social sciences) version 21. Brown’s classification was used to classify maxillary defects in this study. A p value ≤ 0.05 was considered statistically significant. In our study, we included fourteen patients (n = 14), of which anterolateral thigh free flap was used for reconstruction in thirteen cases and in one case free fibular osteocutaneous flap was done. Mean age is 33.36 ± 14 years; there was two flap failure. Flap failure is associated with a statistically significant low swallowing and appearance score (p value is 0.036 for both). The orbital exenteration is associated with low appearance score but it is not statistically significant (p value 0.70), probably due to small sample size in the series. Our early experience of free tissue transfer in maxillary reconstruction is satisfactory in terms of quality of life of the patient as well as the oncological outcome. With positive initial experience in maxillary reconstruction with free flaps large study population will be considered in near future.
