deficiency during embryonic growth have
been researched as possible causes

Treatment
Depending on the involvement of the malformation, surgical treatment
can be limited to reconstruction of the nasal dorsum and apex only or
extend to include maxillary advancement. The treatment consists of:
 Nasal correction. Cranial, costochondral or artificial grafting to the
can be performed in early adolescence; however, osteotomy with
maxillary advancement should be reserved until the late teenage
years [79], if so, ideally, the nasal reconstruction is carried out after
the orthognathic and anterior maxillary augmentation procedures
 Surgeons have reported the use of bone and cartilage grafts, and
a comparison between the two demonstrated that either option is
adequate for creating a normal nasolabial angle and tip projection
[80,81].
