Endoscopic carpal tunnel release has been claimed to offer improvement in recovery time and postoperative discomfort over open carpal tunnel release. Short-incision open carpal tunnel release has been claimed to offer recoveries comparable with endoscopic techniques. Patients receiving carpal tunnel surgery were randomized to short-incision open release or(More)
Benign abdominal cystic tumors are rare. They include retroperitoneal, mesenteric, and omental cysts. Most of these lesions present with vague abdominal pain and nausea. Less commonly they will present with bowel obstruction due to external compression. The diagnosis of these tumors is by abdominal ultrasound or computed tomography. Surgical enucleation is(More)
Bone regeneration promoted by acidic recombinant human fibroblast growth factor (rhFGF-1), rabbit demineralized bone matrix (rDBM), and a fibrin (f) delivery system was measured in critical-sized defects in rabbits' radii. A unilateral segmental defect 20 mm in length was prepared in radii of 48 skeletally mature New Zealand White rabbits divided equally(More)
BACKGROUND The radial forearm fasciocutaneous free flap has become one of the most common methods of reconstructing defects after head and neck ablative surgery. The fasciocutaneous flap is an excellent replacement for the tissue that has been removed. Unfortunately, donor site morbidity remains a problem. Donor site morbidity is primarily related to poor(More)
OBJECTIVES The temporomandibular joint is occasionally encountered in extirpative surgery of the head and neck. It presents a difficult management issue. Little has been reported on functional outcomes after resection and reconstruction of the temporomandibular joint. DESIGN A retrospective analysis consisting of chart reviews and phone interviews was(More)
The lower extremity complications of 100 consecutive patients who required the placement of an intra-aortic balloon pump (IABP) during a 3-year period were studied. Indications for the IABP included hypotension during cardiac catheterization (33%) or coronary angioplasty (13%), hemodynamic instability after open heart surgery (35%), unstable angina (5%),(More)
Migration of silicone beyond the breast implant capsule may occur as a result of silicone bleed, leak, or rupture, and it may indicate failure of implant envelope integrity. We report a series of 23 patients with silicone implants who had axillary lymph node biopsies for palpable masses. Group 1 (n = 15) had biopsies performed an average of 6 years(More)
BACKGROUND AND OBJECTIVES Surgical repair of the acutely fractured orbit strives to restore appearance, preserve ocular and orbital function, and avoid enophthalmos or hypoglobus. Repair is achieved with autologous bone graft, synthetic substitutes, or both. The purpose of this article is to present an alternative procedure--use of implants, cut from a(More)
We conducted a randomly assigned, double-masked, controlled clinical trial to assess the efficacy of 1% apraclonidine hydrochloride in controlling postoperative intraocular pressure increases in patients undergoing extracapsular cataract extraction. Apraclonidine hydrochloride was given either one hour preoperatively or immediately after uncomplicated,(More)
