So I'm Dr. Thomas Lee from Virginia Commonwealth University. I work in the Department of Otolaryngology. The case we're seeing today is a type of case that is relatively common. This is an elderly patient who has multiple skin cancer involving the vertex of his skin. This patient presented with basal cell carcinoma of the scalp, and he had undergone two separate lesions under Mohs surgery. And the resulting defect on one of them left 4x3-cm skin defect down to bare bone, and the other was superficial, but not involving the bone itself, but just down to the pericranium. So the decision was made to reconstruct this area. The top priority in this case is to ensure that the bone itself is covered. And in this situation, we looked at different options because patient has multiple other skin lesions surrounding this area. Instead of using local tissue advancement option, we decide to place an Integra matrix and come back and do a staged skin grafting. The surgical step today is once patient's asleep, we will look at the wound. The wound with the bone exposed - we are gonna remove any remaining granulation tissue and also drill down the surface of the bone so that we get rid of any concern for bacteria left behind. And also to just give us deeper margin along the deep aspect of this area, even though it's been cleared with Mohs surgery. Once we completed that, we then proceed with applying the Integra wound matrix, cutting it to appropriate size, and secure it with a bolster, and the dressing will stay on for about a month. And in a separate surgery about a month from now, we'll come back and place a skin graft.


That's good there. And then let's go ahead and scrape out this granulation tissue. That's probably - yeah, that's just... Okay. Okay. Gotta freshen up those skin edges here. You have a 15 blade?

Some of the skin's rolling in here. Let's cut this out. That's good. Do you have pickups? Then this skin here. Let's cut it down. Okay, let's go ahead and drill this down. Better freshen up all this.

Here's a - needle down. In this case, we're drilling it to get rid of any overlying bacteria from exposure. Also to get slightly additional margin, even though the deep margin was cleared from Mohs surgery. But we want the bone to bleed so that it'll integrate into - help integrate the Integra matrix. The other reconstructive option here is to do local tissue advancement, but in this case, we want to avoid that because he has other surrounding scalp area that has potential for other malignancies. Additional skin cancer sites, so it's better to not use that to reconstruct this area. Oh yeah - do we have the Integra in the room? Bilayer? Yeah. How big is it? What is that, how many is that? 2x2 inch. Okay, let me see. You have a ruler, please? Do we have like Baci or something as well?

Two. That's a five. Okay. This one doesn't really need it. If I was gonna - if there was anything left, I was gonna use that. It's a 2x3, and then this is 4 by - 4x3.5. Yeah, can you open the 2x2 bilayer? Is that what you have over there? Yeah. Is it bilayer? It's double? Yeah, that's good. So open it? Yep. So we'll put down this one first. This area, again, there's stuff on it, which is good. This if you just let it be, it'll heal in all the way. This is not gonna heal at all. See you got other things that may potentially be premalignant.


Okay. Yep. Thank you. Is this one premeshed? [No.] Do you have the scissors? How about some sutures? You have any chromic stuff? I have 3-0 on an SH. And let's save these. I don't know if it's gonna be very useful, but we'll put a suture right here. Let's pack it. Hold on one second, there's something going on.

Hey Kevin, these are pickup-outs. Another pickup, please. One more. Suture scissors. I got it. You got it? Yep. Put one right here. Yep. Let's save those. I might reuse it. All right, let's go do this one right here. Yep. Right there. And this guy we'll use. Okay, one more suture. I'm gonna start sewing this one, Brooks. I'll put one in there. Do you have one more chromic? Otherwise, I'll use... You wanna sew this one in, Brooks? Sure. Then, let me see the Xeroforms. Do you have Baci? Yep. Do you want me to bring this whole little table over there? Do you have Baci? Like a lot of it? Okie dokie. Yeah, nice. Perfect. Get a deep bite, yep. This is gonna be our dressing-making table. Yay! I'm super pumped. And maybe be one at this corner. Okay. Just to tack it down. You got the Xeroform? Yeah, and lemme see the Baci next. Our dressing-making table. I like it. Very fancy. I will make several more fluffs. Scissors. All right. We have silks, right? Might need two packs. I'm not sure if you have... Might need one more pack than that.


Let's do... You got one more of these, the Xeroforms? Yep. Can I get one more of the Xeroform things? We can use that for that one. All right, so when I suture this in, I like to secure it to the skin edge. This Integra material. So just secure it through this, this, and then the skin. We'll leave this long. There's a needle down. Okay, we'll just take that in a second. Let me get more silks. Gonna get one through there. Kind of - let's go ahead and secure that. Let's stop here or here? This one here. Let's just get this in this little tight space here. So just go right through the skin edge. And the point of this bolster is to push it down so it doesn't lift off as it's healing. More, please. Picking all this up, please. Okay, let's do the fluff. You got some mosquitoes? Two's probably good. Then we'll do that, and then we'll do that one next. I'm gonna tie this. Kevin, go ahead. Lemme see the mosquito. Okay. Nice. Okay, good. We haven't done any local yet, are we gonna? No. No local? No local. And just leave it long for now. Okay, now let's go to this one to this one. Then just tie this to this. We'll need more silks, and then I'll take... I have one more loaded up back here. We need another pack. Okay. Scissors first and then - silks, please. Use six, I would say. Get it from all sides. Can I have another silk? Do you have a pickups? Yeah, more pickups. Secure it to the edge. Can I get another silk? I can use this. Here's a brown. That's fine. I'll use this, no worries. Two more, maybe. One, two. There's needle back. Needle back. Gracias. One - last one, yep. All right, the fluffs, please. Got a mosquito? Please? Suture scissors. Okay. We are done. All right, thank you guys.
