Zur postnatalen Entwicklung der Nasenscheidewand
The postnatal development of the nasal septum
Up to now little is known about anatomy and histology and especially about the germinative zones of the growing nasal septum. We totally removed 18 septa of children between 0–10 years immediatly after death. After photographical documentation these septa were studied histologically and microradiographically. It was found that at birth the connection between the cartilaginous septum and vomer only consists of a small and very loose layer of connective tissue. During the first year of life several ossification areas appear between vomer and cartilage in the dorsal part of the septum. An enchondral ossification zone at the rostrum sphenoidale was regularly seen in the neonatal septum, but vanishes soon after birth. The development of the perpendicular plate starts from multiple ossification centers regularly to be found in the dorsocranial part of the neonatal septum. The perpendicular plate is the fastest growing part of the septum and shows still at the 10. year of life an enchondral ossification around its border.
The shape and the size of the septum changes most during the first 6 years; after that time septal growth slows markedly down. As the enchondral ossification zone resembles an epiphysis cartilage it is assumed, that lesions of this area may lead to growth disturbances of the inner and outer nose. Therefore, it is emphasized, that regarding rhinoplasty in children this ossification zone should be preserved by the surgeon.
