[Anatomical and histological observation on soft tissue of nasal dorsum and the nasalis-procerus aponeurosis].
26 nasal specimens of cadavers were studied with anatomical and histological methods. Two layers of collagen fibre arranged in different pattern were found beneath the nasalis transversus and procerus. The superficial layer of compact collagen fibres directly attached to and wraped up nasalis transversus and procerus, and it was named the nasalis-procerus aponeurosis; the deep layer of relatively flexible collagen fibres was loose subaponeuratic tissue. The study showed that soft tissue of nasal dorsum could be divided into four layers; skin, superficial fascia, skeletal muscle and aponeurosis, and loose subaponeurotic tissue. This result provides scientific basis for proper design of rhinoplasty.
