Conventional surgical techniques used for the treatment of nasal devia
tions do not avoid recurrences, especially in inveterate forms, The pr
imary alteration of the nasal osteocartilaginous framework would progr
essively increase and, therefore, could cause changes of structures in
itially not involved by the trauma, such as alar or upper lateral cart
ilage. According to our analysis, it is supposed that the septal peric
hondrium is capable of restoring its previous position, This happens e
specially in the inveterate forms of deviation and even when the septa
l straightening has already been done. The anatomopathological study p
oints out the constant presence of the fibrous thickening of the peric
hondrium at the same level as the concave portion of septum, and this
finding represents the anatomical expression of the scarring reaction
after the traumatic event, The fibroperichondrium is excised as radica
lly as possible for the entire bilateral surface of the chondral septu
m, Good results by extramucosal perichondrectomy, associated with more
conventional procedures of septum correction, in a series of 20 selec
ted patients has encouraged reporting of the technique.
