Operative Report PREOPERATIVE DIAGNOSIS: Spinal cord stimulator battery replacement POSTOPERATIVE DIAGNOSIS: Spinal cord stimulator battery replacement OPERATION PERFORMED: Removal of spinal cord stimulator batteries and replacement with new batteries INDICATIONS: The patient was a 67-year-old male who had a spinal cord stimulator implanted approximately five years ago. He returned because of lack of functioning in this system. A decision was made to proceed with removal of the old batteries and replacement with new ones. The patient understood the risks and benefits of the procedure. DESCRIPTION OF PROCEDURE: The patient was placed in supine position, and the area where the batteries were located on the left side was prepped and draped in sterile fashion. The patient was infiltrated with lidocaine 1 percent. The area was reopened with a #15 blade, and the batteries were removed from the pocket and disconnected from the lead wires. A new battery system was reconnected. The wound was closed with 3-0 Vicryl and staples for skin. There were no complications and no specimens. Procedure code:

Operative Note: Chalazion incision and drainage of the right eyeDescription of Procedure: The right eye was prepped and draped for the procedure. Chalazion forceps were used to grasp the upper eyelid. The surface of the chalazion was incised. The contents of the chalazion were curetted. Chalazion forceps were removed. Hemostasis was achieved. Neomycin, polymyxin B, and dexamethasone ointment was placed in the eye with an overlying eye pad. The patient was transferred to the recovery area in stable condition.

Operative Report PROCEDURE: Pterygium removal with conjunctival graft, right eye PROCEDURE DETAILS: Local anesthesia was achieved with a 50:50 mixture of 2 percent lidocaine and 0.75 percent bupivacaine with hyaluronidase. The eye was prepped and draped in the usual sterile fashion. The lashes were isolated on Steri-Strips, and the lids separated with the wire speculum. The pterygium was marked with a marking pen, and subconjunctival injection of 1 percent lidocaine with epinephrine was injected underneath the pterygium. The pterygium was then resected, and the body of the pterygium was resected with sharp dissection with Westcott scissors. The head of the pterygium was dissected off the cornea with Martinez corneal dissector. The cornea was then smoothed with an ototome burr. Hemostasis was achieved with bipolar cautery. A conjunctival graft measuring 10 mm × 8 mm was harvested from the superior bulbar conjunctiva by marking the area and injecting it with subconjunctival 1 percent lidocaine with epinephrine. This was dissected with Westcott scissors and sutured in place with multiple interrupted 9-0 sutures. Subconjunctival dexamethasone and gentamicin injections were given. A bandage contact lens was placed on the eye. Neomycin, polymyxin B, and dexamethasone ointment was placed on the eye. A patch was placed on the eye. The patient tolerated the procedure well and was taken to the recovery room in good condition. First-Listed Diagnosis: First-Listed Procedure:
