Özet

Comprehensive knowledge of nasal anatomy is essential for obtaining aesthetically and functionally pleasing results in rhinoplasty. In this study, the authors described the anatomy, histology, and clinical relevance of the interdomal region, keystone, and scroll complex. The current study examined these areas in 26 fresh cadaver heads. All cadavers were fresh, and no conservation or freezing processes were applied. All dissections were performed by the first author. It was determined that the structure that connected the middle crura in the interdomal region actually came together in the transverse plane and contained abundant capillaries within. It was observed that chondroblasts with high regenerative potential were present in the keystone area, and there was very tight attachment between periosteum and perichondrium. The scroll complex was found to be more flexible and thin and had fewer regenerative cells compared to the keystone region. With its unique anatomy and histology, the keystone acts as a transition area between the flexible and fixed units of the nose. The scroll complex should be taken into consideration during rhinoplasty because of its effects on fixation of the skin in the lateral supratip area and functional effects on internal and external nasal valves. The interdomal ligament, in contrast, acts as a transition between both middle crura rather than a real ligament.
