PURPOSE Simple limbal epithelial transplantation (SLET) and cultivated limbal epithelial transplantation (CLET) are proven clinical techniques for treating limbal stem cell deficiency (LSCD). However, the ideal size and number of the limbal explants required for transplantation has not been clearly elucidated. This in vitro study aimed to determine the optimal limbal explant size required for c...

OBJECTIVE To evaluate the horizontal mattress technique in microvascular anastomosis for size-mismatched vessels. METHODS The present study involved cadaveric simulation using size-mismatched (1.5:1) Thiel-embalmed cadaveric arteries. The authors performed horizontal mattress anastomoses using 9-0 nylon suture and recorded the procedure. Vessel patency was evaluated by saline infusion. Vessel...

Objective: To examine the validity of using cadaveric spines of deer or boars for biomechanical experiments as substitutes for the cadaveric spine of humans. Materials and Methods: Five specimens of the L3-4 functional spinal unit of human cadavers, mature deer and mature boars were prepared according to 3 models: 1) normal model, 2) injured model and 3) pedicle screw fixation model and they we...

OBJECTIVES/HYPOTHESIS Extirpation via expanded endonasal approaches (EEA) to the skull base can result in defects requiring vascularized rotational flap reconstruction. The buccal fat pad (BFP) is a vascularized graft described in open skull base resections, but its harvest and adequacy of vascular supply have not been examined for use with EEA. STUDY DESIGN A transfacial cadaveric dissection...

Objectives: To describe the versatility of acellular fetal bovine dermal matrix as an alternative to human cadaveric allograft for head and neck reconstructive procedures in children. Study Design: Case series with chart review. Methods: A database of pediatric operative procedures was queried for the use of acellular fetal bovine dermal matrix over a 16-month period. Indications for reconstruc...
