description BACKGROUND: An understanding of the soft tissue layers in the mastoid region has become important for otologic reconstructive surgery. The objective of this study was to clarify the surgical anatomy of the soft tissue layers in the mastoid region and reveal its clinical significance. METHODS: Cadaveric study. RESULTS: Our dissections showed the soft tissue layers consisting of skin, subcutaneous layer, superficial and deep mastoid fasciae, and periosteum. The superficial mastoid fascia was continuous with the temporoparietal fascia cranially and the superficial cervical fascia caudally. The deep mastoid fascia could be clearly separated from the superficial mastoid fascia and has continuity to the loose alveolar layer in the temporoparietal region. However, it caudally fused with the fascia and ligament of the sternocleidomastoid. CONCLUSIONS: A comprehensive understanding of soft tissue layers would improve otologic reconstructive surgery. LEVEL OF EVIDENCE: NA
