    Abstract:
    BACKGROUND: Free tissue reconstruction is reliable in suitable patients but patient selection remains a challenge for the reconstructive surgeon. The anterolateral thigh (ALT) free flap and pedicled pectoralis major myocutaneous flap (PMMF) are two common reconstructive options for a lateral temporal bone resection defect. The threshold at which free tissue reconstruction should be considered over locoregional reconstruction is not defined. We sought to define reconstructive flap choice in the setting of medical comorbidities that may dissuade free tissue transfer. METHODS: A retrospective analysis of lateral temporal bone defects at a single institution was undertaken. The primary outcomes were flap survival, surgical complications and durations of surgery and stay. Data regarding medical comorbidities and potential confounders were examined. RESULTS: Sixty patients with lateral temporal bone defects were identified. Twenty-four (40%) patients underwent PMMF reconstruction and 36 (60%) were reconstructed with ALT. The former were significantly older (73 versus 62 years), though with similar Anesthesiologists Risk Classification System status. Free-flap reconstruction resulted in significantly less flap loss (two versus six) but a longer operating time (790 versus 671 min). CONCLUSION: Patients suffering head and neck cancer with medical comorbidities can make selection of a suitable reconstruction difficult. We found that while patients undergoing ALT reconstruction were typically younger, the comorbidity profile of those patients was similar to patients undergoing PMMF reconstruction. ALT flaps were more reliable than the PMMF, lending credence to the view that free tissue transfer should be the preferred reconstructive option in suitable candidates and defects.
