+<WRAP group>
+<WRAP half column>
+The patient was brought to the operating room where general anesthesia was induced in the usual fashion. She was positioned prone with her head on a horseshoe. Two incisions were marked, perpendicular to the coronal suture, above the superior temporal line, where the skull angles in medially.
+She was prepped and draped in the usual fashion. The left incision was opened with a skin knife and then bovie electrocautery, and the loose areolar tissue was cleared away with a bovie anteriorly and posteriorly. Then, parallel marks were marked with the bovie, 1.25 cm left and 1.25 cm right of the coronal suture, parallel to the suture. The coronal suture was clearly closed. The loose areolar tissue was cleared away down to the squamosal suture and medially to the midline. This was repeated on the right side. In this fashion, we could use the endoscope contralaterally for the dissection from lateral to medial, which allows for excellent visualization.
+We started bone removal on the left. We made two burr holes, one anterior and one posterior to the fused coronal suture, and connected them with a kerrison. I then cleared away the dura medially with a #1 penfield, and using the endoscope for visualization, made two parallel cuts along the suture most of the way to the fontanelle with Tessier bone scissors. I then removed that bone with large Leksell rongeurs. Once I was satisfied with bony removal, I proceeded to repeat this procedure from the burr holes inferiorly to the skull base, visualizing the middle fossa floor and the sphenoid as well.
+I then repeated the whole procedure on the right side, although I was able to remove the right medial bony strip en bloc with a combination of tessier scissors and a bovie as it dissected free more easily from the dural reflection at the fontanelle.
+Hemostasis was obtained with bone wax and surgiflo through the case.
+The wound was then thoroughly irrigated with antibiotic-impregnated saline. The incision was then closed with interrupted 3-0 Vicryl in the galea and running 4-0 monocryl in the skin. The hair was washed the wound was dressed with antibiotic ointment.

+====Unilateral Cleft Lip Repair with Nose/Septum Revision====
+The oral cavity was cleansed with Peridex mouthwash. The face was prepared and draped in a sterile fashion. The eyes were protected with Steri-Strips. A moistened throat pack was placed in the oropharynx. Fisher subunit approximation cleft lip repair was then marked out with limb dimensions as above; the key landmark points were tattooed with 25-gauge needle and methylene blue.
+The medial lip cuts were then made with a 6700 Beaver blade with marginal tissue discarded; the overlying skin and underlying labial mucosa was then minimally undermined for a distance of 1-2 mm. We confirmed that the Cupid's bow was level, and the medial triangle opened to the planned 1.5 mm.   Accordingly, the lateral lip upper buccal sulcus incision was then made, and the lateral lip element was mobilized in a supra-periosteal plane. The abnormal attachments of the facial musculature were released off the pyriform, as were abnormal attachments of the cleft-side lower lateral cartilage.
+We then turned our attention to the septoplasty portion of the operation. The caudal septum was noted to be acutely deviated to the non-cleft side. Via the medial lip incision, we were able to carefully expose the caudal septum and developed a sub-mucoperichondrial plane on the non-cleft side. The abnormal attachments of the caudal septum were then released with a Cottle elevator. The septum was then repositioned to a midline position.
+Then, the lateral lip element incisions were made with a 6700 Beaver blade, and the marginal cleft tissue was discarded. The overlying skin and underlying labial mucosa were then undermined widely in an effort to relieve all tension on the closure.
+Please note that due to the significant width of this complete cleft approximately 50% of increased procedural time and effort was required to fully mobilize the lateral lip element mucosa and skin to achieve tension-free closure, justifying the application of Modifier 22.
+The lateral nasal wall lining was released within the cleft in the coronal plane by incising intra-nasally up to the inferior turbinate, allowing for anterior transposition of the cleft-side lateral nasal vestibular lining.
+Attention was then turned to the tip rhinoplasty portion of the operation. Via the superior aspect of the lateral lip element incision, we were able to dissect carefully both superficial and deep to the cleft-side lower lateral cartilage to allow for differential re-draping of the skin envelope and the vestibular lining, respectively. Given the severity of the cleft lip nasal deformity, approximately 30% of increased procedural time and effort was required to fully mobilize the intra-nasal vestibular lining and to reposition the cleft-side lower lateral cartilage (LLC) into the proper position, justifying the application of Modifier 22.
+Once this was completed and the cleft-side lower lateral cartilage was mobilized, we placed a scroll area plication suture with 5-0 Monocryl to re-drape the cleft-side LLC into the appropriate position in relation to the upper lateral cartilage. Multiple alar transfixion sutures were then also placed in a triangular configuration to re-drape the vestibular lining with 5-0 Monocryl. Several of these alar transfixion suture were placed to define the ala-cheek crease and re-drape the vestibular lining.
+Copious irrigation with bacitracin-containing solution was then applied; hemostasis was achieved with bipolar cautery.
+The nasal floor was closed by approximation of the lateral nasal lining and the mucosa on the repositioned caudal septum with 5-0 Monocryl suture in an interrupted fashion, thereby, in effect, closing the type VII naso-labial fistula in the process and separating the nasal cavity from the labial area. Care was taken to pass at least one suture through the caudal border of the septum cartilage to secure it in the midline position.
+The labial mucosa and upper buccal sulcus incisions were closed with interrupted 5-0 Monocryl suture. The orbicularis oris muscle was then carefully approximated with a 5-0 Vicryl suture, with care taken to align the nasal, labial, and marginal components of the muscle. Finally, the dermis was approximated with 5-0 Vicryl and 5-0 Monocryl suture. The nasal sill, vermilion, cutaneous triangle, and cutaneous roll were inset and closed with interrupted 8-0 Vicryl sutures. Finally, the rest of the lip was approximated with carefully placed 7-0 Prolene sutures.
+Nasal stents (size 2) were then cut to the appropriate length, introduced to each naris, and secured with a loosely tied 3-0 Prolene suture.
+The upper lip incision was then dressed with bacitracin ointment. The throat pack was removed, and the oropharynx was suctioned.
+At the end of the operation, all sponge and needle counts were correct. The patient tolerated the operation well. The patient's care was then turned over to the Anesthesia team. The patient emerged from the anesthetic uneventfully and was transported to the recovery room in stable condition.
+Resident:\\
+Marking instructions: Fisher repair. Marks alar rim stopping at the mid alar point. Next marks nasal-cheek junction and stops at subalare. These two points make a line and allow placement of the nasal sill mark. This is an intersection with a bowtie semicircular line with the columellar midline and side points. Transposes these marks to the lateral side. Draws cupid bow points. Now you can measure the total lip height (TLH usually around 8), and greater lip height (GLH usually around 6). Subtract these and rose thompson effect to get the lesser lip height (LLH). Note that this is the base of the triangle. Make the backcut perpindecular to the GLH line.\\

+====Sagittal strip craniectomy with biparietal morcellation====
+<WRAP group>
+<WRAP half column>
+The patient and the patient's family were met in the pre-operative area.
+The surgical site was marked with the surgeon's initials.
+The risks, benefits, details, and alternatives of the operation were discussed in detail. All questions were answered. The informed consent for surgery was signed by parent/guardian.
+The patient was brought into the operating room and laid supine on the operating room table. General anesthesia was induced by the Anesthesiology provider. A pre-operative intravenous dose of antibiotics was administered.
+A time-out was performed during which we identified the operation and the operative site. All team members introduced themselves. All issues and concerns were discussed and resolved before proceeding with the operation.
+The eyes were protected with Tegaderm tapes.
+A bicoronal sinusoidal incision was designed from ear to ear and infiltrated with local anesthetic; local anesthetic, 0.25% bupivacaine with 1:200,000 epinephrine, was infiltrated into the proposed surgical site(s), with appropriate weight-based dosing. The hair around the incision was minimally shaved.
+The surgical site was prepared and draped in a sterile fashion.
+The incision was made with a 15-blade and monopolar cautery down through the galea; wide, bidirectional sub-galeal undermining and scalp mobilization was performed to expose the cranium from frontal to occipital bones. The sagittal suture was noted to be fused; the metopic, bilateral coronal and lamboid sutures were noted to be open.
+Three pairs of parasagittal burr holes were made along the planned parasagittal cuts from the anterior fontanelle to the lambda.
+A 3-cm strip craniectomy centered over the fused sagittal suture was then performed from anterior fontanelle to the lambda, after burr holes were made and the dissection proceeded across the midline and bone was removed across the midline with Kerrison rongeurs; there were no dural tears, and the patient remained hemodynamically stable.
+As bilateral frontal cranioplasty and remodeling, a caudally-based barrel stave (approximately 2 cm in width) straddling the open RIGHT coronal suture was cut with a craniotome, dissected off the dura, out-fractured as a green-stick fracture with a Tonsil clamp, and contoured into the appropriate more rounded shape with a Tessier elevator.
+Then, a caudally-based barrel stave (approximately 2 cm in width) straddling the open LEFT coronal suture was cut with a craniotome, dissected off the dura, out-fractured as a green-stick fracture with a Tonsil clamp, and contoured into the appropriate more rounded shape with a Tessier elevator.
+Then, bilateral, extensive parietal morcellation cuts were designed and then cut with a craniotome in a brick-type pattern, spanning an expanse of 6.5 to 7.0 cm from parasagittal edge of the sagittal craniectomy to the superior temporal crest, with two bone graft (flaps) caudally and three bone graft (flaps) toward the midline. These extensive bone grafts were retained with their attachment to dura and secured in placed with a Surgicel. This was done on the right side first, and then the left side.
+A 7-French flat Jackson-Pratt drain was placed through the RIGHT occiput.
+Copious irrigation was applied with at least 1 liter of normal saline; hemostasis was noted. The scalp was then closed in layers, with 3-0 Vicryl for the galea layer, followed by a running 4-0 Monocryl suture on the surface; bacitracin was applied to the incision.
+Please note that Modifier 22 applies to all components of this operation as significantly increased operative time and technical effort were required to safely achieve all steps of this operation. This was primarily because of thicker bone in the bilateral parietal and frontal regions, which rendered every part of the operation more challenging, including, but not limited to, making burr holes, craniotomy cuts, and reshaping of the barrel staves, among other steps. These circumstances and findings justifies the application of Modifier 22.
+At the end of the operation, all sponge and needle counts were confirmed to be correct.
+The patient tolerated the operation well.
+The patient's care was then turned over to the Anesthesia team.
+The patient emerged from the anesthetic uneventfully and was transported to the recovery room in stable condition.
