This Concept Map, created with IHMC CmapTools, has information related to: Third Eyelid Repair, Step 2: Grasp the third eyelid with mosquito hemostat or forcep (1st clamp) at the free margin (Since it is being removed, it can be damaged by clamping at the free margin). Step 3: Bring the third eyelid all the way across the eye. It is extremely thin dorsally and ventrally. It is thicker in the middle due to the cartilage body, which is “T” shaped and a gland. Step 4: Look for the thinner areas dorsally and ventrally – place one mosquito hemostat on each area (2nd and 3rd clamp), from the free edge, far towards the medial cantus as possible, without clamping the cartilage body. Make sure not to clamp the eyelid conjunctiva as well., Step10:If there is fat prolapse, re-sedate the patient and suture the cut edges. squamous cell carcinomas begin here and so if it is believed that it is one, this procedure should be done. Step 11: Suture repair of the excised margins of the third eyelid can be performed; however, conjunctiva heals adequately by second intention, and the potential of iatrogenic irritation to the cornea from placement of suture near the globe is a good reason for not suturing the wound. The surgical site to heal by second intention. Post- op Care, Step 8:Now the third eyelid is out. Keep the clamps on for 15 minutes to control hemostasis. Release the forceps gently afterwards. Step 9: Before you remove the last hemostat/forceps/clamp, check for signs of hemostasis and fat prolapse. After removal of the hemostatic forceps, retrobulbar adipose tissue may occasionally prolapse from the medial canthus region. This tissue may also be excised using scissors without any untoward effects. Step10:If there is fat prolapse, re-sedate the patient and suture the cut edges. squamous cell carcinomas begin here and so if it is believed that it is one, this procedure should be done., Step 4: Look for the thinner areas dorsally and ventrally – place one mosquito hemostat on each area (2nd and 3rd clamp), from the free edge, far towards the medial cantus as possible, without clamping the cartilage body. Make sure not to clamp the eyelid conjunctiva as well. Step 5: Use a scalpel, elevate the dorsal forceps (2nd clamp) and hand cut along it, removing conjunctiva as you go. Do not unclamp the forceps. Step 6: Elevate the ventral forceps and cut along it as well (3rd clamp). Do not unclamp the forceps., Step 6: Elevate the ventral forceps and cut along it as well (3rd clamp). Do not unclamp the forceps. Step 7: Place the 4th clamp at the base of the third eyelid now. Cut along it with a scalpel blade. Step 8:Now the third eyelid is out. Keep the clamps on for 15 minutes to control hemostasis. Release the forceps gently afterwards., THIRD EYELID REMOVAL PROCEDURE Step 1: Prolapse the third eyelid slightly by retracting the eye. Step 2: Grasp the third eyelid with mosquito hemostat or forcep (1st clamp) at the free margin (Since it is being removed, it can be damaged by clamping at the free margin).
