Objectives: In this study, a modified surgical method
was carried out to repair large nasal septal perforations
with a galeal pericranial flap using endoscopic technique.
Materials and Methods: Six adult human cadavers
were dissected by applying the classic open rhinoplasty
technique. Large perforations were created in
the septal cartilages. To repair the perforations, we
prepared galeal pericranial flaps with supraorbital
neurovascular pedicles and calvarial bone grafts under
endoscopic visualization. The flaps were inserted
between the upper lateral cartilages and folded into
three layers. The flaps were sutured to the nasal mucosa
with absorbable sutures. The length, the width, the
size of the flaps and the perforations were measured
using an electronic caliper and a flexible ruler.
Results: The mean length and width of the flap pedicles
were measured as 26.8±5.1 mm (range 20 to 32 mm)
and 19.3±2.6 mm (range 15 to 23 mm), respectively.
In addition, the mean length and the width of the flaps
were 54.1±4.9 mm (range 50 to 60 mm) and 51.6±7.8 mm
(range 45 to 63 mm), respectively. All of the nasal septal
perforations were repaired with a galeal pericranial flap.
Conclusion: The galeal-pericranial flap is well-vascularized
and similar to the nasal mucosa for tissue thickness.
Therefore, reconstruction with galeal-pericranial
flaps can be an alternative surgical technique for repair
of large nasal septal perforations.
