This overview addresses the multifaceted approach required for the reconstruction of head and neck deformities resulting from trauma or neoplasms. The reconstructive strategy is contingent upon various factors, including etiology, defect extent, and patient health status. Free flaps are frequently the preferred reconstructive option due to local tissue scarcity and the challenges associated with regional tissue recruitment. An in-depth understanding of head and neck cancer treatments, lymph node dissections, and the effects of radiotherapy on the surgical plan is crucial. Furthermore, preoperative planning must incorporate nutritional assessments and airway management strategies in addition to a meticulous patient evaluation for successful outcomes. Additionally, the text delves into specific reconstruction scenarios including scalp, tongue, mandibular, and pharyngeal reconstructions, emphasizing the selection of appropriate reconstructive techniques and potential complications.
