The Effect of Autologous Fat Graft with Different Surgical Repair Methods on Nerve Regeneration in a Rat Sciatic Nerve Defect Model.

Background: The aim of this study was to evaluate the efficacy of autologous fat graft with different surgical repair methods on reconstruction of a 10-mm-long rat sciatic nerve defect model.

Methods: One hundred forty-four sciatic nerves were operated on in 72 Wistar rats. The right limbs were assigned as group A (n = 72) and the left limbs as group B (n = 72).

Reverse superior labial artery flap in reconstruction of nose and medial cheek defects.

Background: Angular artery, lateral nasal artery, and infraorbital artery pedicled nasolabial flaps have been used for reconstruction of lower nose and medial cheek defects. An alternative pedicle to raise a flap in the nasolabial area is the superior labial artery. Superior labial artery is a constant branch of the facial artery, arising above or at the angle of mouth and anastomoses with its counterpart in the middle of the upper lip.

A novel approach to cleft lip nose deformity: posterior dome graft technique.

The pathology of "nasal tip complex" remains as a problem to be solved in unilateral cleft lip nose deformity wherein open rhinoplasty and cartilage grafts are used frequently. For this reason, the research for the treatment of cleft-side tip projection lost and ala depression still continues. Our technique is to put the cartilage graft at posterior dome area after the release of cleft-side ala from vestibular mucosa and skin to elevate the ala depression and tip projection.

Reconstruction of lower half defects of the nose with the lateral nasal artery pedicle nasolabial island flap.

Background: The superiorly based nasolabial flap is a well-known procedure. However, random pattern or subcutaneous pedicle flaps are insufficient for reconstruction of large defects. Artery pedicle flaps have a satisfactory blood supply, and for that reason, the required tissue can be raised for reconstruction of large defects of the nose.
