In addition to the conjunctival autograft
, a part of the limbal stem cells is included that aids in the complete anatomic and physiologic reconstruction of the excised pterygium area.
The need for a longer period of protection was highlighted in an animal study by Jackson and colleagues (34) in which they compared BPTB autograft
and fresh frozen BPTB allograft ACL reconstructions and found that after 6 weeks, the autografts
had a greater cross-sectional area compared to the allograft.
Gobbi and Foster TE et al compared the biological incorporation and mechanical properties of allografts and autografts
in a sheep model.
Rates of engraftment at postoperative day 14, however, significantly favored the expanded split-thickness skin autografts
group at 96.
The patient was cooled 26[degrees]C and following cardioplegic diastolic arrest the pulmonary autograft
in the aortic position was incised.
Current use indicates that surgeons prefer ceramic, autograft
bone, and plastic pore prostheses.
The study was a direct comparison of StrataGraft([R]) to the standard of care which currently requires the harvest of an autograft
from the patient's uninjured skin for transplantation.
They underwent pterygium excision with Conjunctival autograft
10) Some investigators have found increased rates of clinical failure compared to autografts
Ultimately, the question of preference of pulmonary autografts
over mechanical prostheses in adolescents winds down to choice of complications of the one therapy over the other and must be based on preferred life style by the individual patient and family.
All conjunctival autografts
in both groups were successfully attached and were in fact after 2 months.
were obtained utilizing a midline skin incision from the inferior pole of the patella to the tibial tubercle.
