KEY POINTS
·In recent years, a complete cure of the disease is still a huge
challenge for ENT doctors.
· This advanced surgical method are more suitable for the those
refractory LCG who have no response to the standardized medical
treatment and voice correction for 3 months.
· Application of local flipped pedicle microflap combined with
botulinum toxin A injection in the treatment of refractory LCG is
effective and safe.
·Based on the principle of preserving normal mucosa, the surgery can
achieve the lesion clearance, restore the integrity of vocal fold
cover-body, preserve the perichondrium, and reserve a time window for
microflap recovery.
·Precision operability with great patience and caution is needed in the
surgery. The microflap tension should be appropriate, the torsion or
fenestration should be prevented from necrosis of the mucosa, and the
fully mucosal coverage of the surgical wound is the key to the success
of the operation.
