ABSTRACT
OBJECTIVE To investigate the optimal surgical approach and compatible material for large nasal septal perforation.METHODS Operations were underwent via labiogingival groove approach under endoscope.Double layer of flaps were perichondrium of nasal septal cartilage,base of nasal cavity and inferior nasal meatus on the left and acellular dermal matrix (ADM) on the right and the two flaps were adhered with ear-cerebral glue (EC).RESULTS All of 36 cases were successfully repaired and no reperforation occurred after following-up for 3 months to 2 years.CONCLUSION Large mucosal flaps with wide pedicel and abundant blood supply and ADM of good biocompatibility provide a higher survival rate of the flaps.This method has the advantages of wide field of vision,less damage of the donated area and short time of operation.It is an optimal and practical method for repair of the large nasal septal perforation.
