Minimally Invasive Radioguided Parathyroidectomy
videoMinimally Invasive Radioguided Parathyroidectomy Author: Joshua Hagood Performing surgeon/coauthor: Brendan C. Stack, Jr., M.D., FACS, FACE Department of Otolaryngology - Head and Neck Surgery, University of Arkansas for Medical Sciences, Little Rock, AR, USA Overview: Primary hyperparathyroidism is a disease caused by overproduction of parathyroid hormone (PTH). This condition is most commonly caused by a solitary, hyperfunctioning, adenoma among one of the four parathyroid glands. The hallmark finding of hyperparathyroidism is hypercalcemia which can manifest symptomatically as nephrolithiasis, diabetes insipidus, renal insufficiency, bone pathology, gastrointestinal symptoms, and neuropsychiatric disturbances (remembered as “Stones, Bones, Groans, and Psychiatric overtones”). Minimally invasive Radio guided Parathyroidectomy (MIRP) is a curative procedure for primary hyperparathyroidism that can use both radionuclide guidance and intraoperative PTH measurements to confirm the removal of the offending adenoma. Radionuclide guidance is performed via the injection of 99mTc-sestamibi, which is a radiomarker that sequesters within adenomatous/hypermetabolic parathyroid tissue. Intraoperatively, the amount of 99mTc-sestamibi within excised tissue can be measured with the use of a handheld gamma probe. Instrumentation: -Endotracheal Nerve Integrity Monitoring System (NIMS) -Gamma Probe -Intraoperative PTH assay equipment

Laparoscopic Orchiopexy: Use of a Hitch Stitch
videoContributors: John Paddack (University of Arkansas for Medical Sciences) INTRODUCTION AND OBJECTIVES: The percutaneous hitch stitch, a commonly described technique for elevation of the ureteropelvic junction during laparoscopic pyeloplasty, allows for easier dissection and suturing. We have adapted this technique to laparoscopic orchiopexy. METHODS: The technique described was used for testicular retraction during three consecutive cases of right-sided intraabdominal testicle RESULTS: There were three cases of non palpable testicle, mean age 31 months (range 22-42). Testicles were all within 3 cm of internal ring on laparoscopy. In all cases, testicle was placed in subdartos pouch in single stage, without division of the spermatic vessels. There were no complications. CONCLUSIONS: The percutaneous hitch stitch is a simple modification to the traditional laparoscopic orchiopexy. It provides atraumatic retraction of the intraabdominal testicle and facilitates dissection of spermatic vessels from the posterior peritoneum. DOI: http://dx.doi.org/10.17797/n1nnrufxpt

Mandibular Distraction for Micrognathia in a Neonate
videoIntroduction Patients with Pierre-Robin Sequence (PRS) suffer from micrognathia, glossoptosis, and upper airway obstruction, which is sometimes associated with cleft palate and feeding issues. To overcome these symptoms in our full-term male neonate patient with PRS, mandibular distraction osteogenesis was performed. Methods The patient was intubated after airway endoscopy. A submandibular incision was carried down to the mandible. A distractor was modified to fit the osteotomy site that we marked, and its pin was pulled through an infrauricular incision. Screws secured the plates and the osteotomy was performed. The mandible was distracted 1.8 mm daily for twelve days. Results During distraction, the patient worked with speech therapy. Eventually, he adequately fed orally. He showed no further glossoptosis or obstruction after distraction was completed. Conclusion In our experience, mandibular distraction is a successful way to avoid a surgical airway and promote oral feeding in children with PRS and obstructive symptoms.

Upper Eyelid Blepharoplasty
videoIntroduction: Cosmetic Upper Blepharoplasty involves removing excess skin from the upper eyelid to enhance the appearance of the upper eyelids. Methods: Markings were made for the inferior incision on the upper eyelid between 8-10 mm above the upper lash line. Forceps are used to pinch the excess upper eyelid skin in the middle, nasal, and temporal, aspects of the upper eyelid. Markings are then made superiorly at the middle, nasal, and temporal points and are connected. Toothed forceps are used to pinch the excess upper eyelid skin, using the markings as a guide. Iris scissor is used to excise the pinched excess skin and the underlying orbicularis muscle. The skin between the two eyelids was closed. Conclusions: In our experience, cosmetic upper blepharoplasty is an efficient way to enhance the appearance of the eyes.

Laparoscopic Right Salpingo-oophorectomy in a patient at 17 weeks gestation
videoIntroduction: The prevalence of adnexal masses in pregnancy ranges from 0.05 to 2.4 percent and approximately 1 to 6 percent of these masses are malignant. Patients typically present on prenatal ultrasound asymptomatically but some can have abdominal and back pain as well. Concerns for the fetus and complications in pregnancy cause surgeries to be postponed until after delivery; however, some adnexal masses require evaluation for malignancy. We present a case of a 28-year-old female with a cystic adnexal mass that required laparoscopic salpingo-oophorectomy at 17 weeks gestation. Methods: After the patient was prepped and draped,the initial laparoscopic port was placed in the left upper quadrant, 3 cm below the costal margin and in the midclavicular line. This area, known as Palmer’s point, was chosen as the site for the initial port placement in order to avoid the gravid uterus. After intraperitoneal placement, the abdomen was insufflated with CO2 gas. Laparoscopic ports were placed at the umbilicus and in the right lower quadrant under direct visualization. The port placed at the umbilicus was an Applied Medical GelPOINT Advanced Access Platform. The entire abdominal and pelvic cavities were examined for any lesions. An initial washing was done to examine for malignant cells. The left ovary was examined and determined to be normal. The right ovary was noted to be enlarged, to approximately 10 cm, and was displaced into the posterior cul de sac. Next the infundibulopelvic ligament, broad ligament, ovarian vessels, and ureter are identified. The ureter, which is typically able to be identified at the pelvic brim where it crosses over the bifurcation of the iliac vessels and passes medially, was noted to be well below the plane of dissection. If the ureter is unable to be located trans-peritoneally, a peritoneal incision can be made parallel to the ovarian vessels and the ureter located retroperitoneally in the medial leaflet of the broad ligament. The right fallopian tube and right utero-ovarian ligament were transected using the Ligasure bipolar device. We evaluated for hemostasis of the pedicles. The right suspensory ligament of the ovary containing the ovarian vessels was then isolated and cauterized and transected using the Ligasure bipolar device. A laparoscopic retrieval bag was introduced through the GelPOINT advanced access platform, the specimen was placed in the bag, and then the bag was brought to the surface of the patient's abdomen. We were able to drain straw colored fluid from the cyst with the cyst contained safely within the bag. The remainder of the specimen was then able to be removed, contained within the bag. The patient’s abdomen was deflated and the ports were removed. The fascia at the umbilicus was closed with an 0 Vicryl (polyglactin) suture so as to avoid herniation at the site of the larger incision accommodating the GelPOINT. The rest of the ports were closed using subcuticular sutures. Discussion: Pathology revealed a mature cystic teratoma. The patient was discharged home on the same day of surgery with no complications. Fetal heart tones were within normal limits pre- and post-procedure. Laparoscopic surgery is a safe treatment for pregnant women with non-obstetrical surgical issues, including adnexal masses.

Ahmed® Glaucoma Valve for Treatment of Refractory Glaucoma
videoIntroduction Intraocular pressure is the single modifiable risk factor resulting in progression of various subtypes of glaucoma. Intraocular pressure control is often achieved with topical medications, outpatient laser procedures, or minimally-invasive glaucoma surgery (MIGS). This patient is a 63-year-old with traumatic glaucoma in the right eye with elevated intraocular pressure sub-optimally controlled despite maximum medical therapy (29 mmHg). His intraocular pressure must be controlled with incisional glaucoma surgery - in this case, with placement of an Ahmed Model FP7 glaucoma valve. An advantage of valved glaucoma shunts is lower risk of postoperative hypotony-related complications compared to non-valved glaucoma shunts. Methods The 10 and 12 o'clock meridians are marked with a marking pen to define the borders of the conjunctival peritomy. A limbal traction 6-0 Vicryl suture is placed superotemporally in the cornea at the limbus. The conjunctival peritomy is then completed using Westcott scissors along the predetermined marks. The peritomy is extended posteriorly with blunt dissection using Stevens tenotomy scissors. Wet field cautery is used to achieve hemostasis of the scleral bed. A Stevens tenotomy hook is used to identify the superior rectus muscle and a marking pen is used to mark its border. The Ahmed Model FP7 tube shunt is then introduced onto the surgical field. Balanced salt solution is injected into the tip of the tube using a 30-gauge cannula to ensure adequate patency of the valve. The Ahmed plate is then sutured to the sclera approximately 8 mm posterior to the limbus using 5-0 Nylon suture. A corneal paracentesis is made at the 8 o'clock position, and viscoelastic is injected to deepen the anterior chamber. A 23-gauge needle attached to the Healon syringe is then used to tunnel from a point 2.0 mm posterior to the limbus into the anterior chamber. The needle tract is anterior and parallel to the plane of the iris and the surgeon must ensure that the tube does not contact the iris or corneal endothelium after insertion. The implant tube is then laid flush with the cornea and shortened with Westcott scissors with an oblique cut, bevel up. Healon is injected as the needle is withdrawn. Non-toothed forceps are then used to insert the tube into the anterior chamber. A single 8-0 Vicryl suture is used to secure the tube to the underlying sclera. A corneal patch graft is cut to fit the site of tube implantation and secured with a single 8-0 Vicryl horizontal cross mattress suture. The conjunctival peritomy is then closed with a running 8-0 Vicryl suture on a BV needle. Anchoring sutures incorporating the conjunctiva and the episclera to firmly secure the corners of the peritomy to the limbus. A 9-0 Nylon suture is used to re-approximate the limbal conjunctiva. At the conclusion of the case, the eye is returned to a neutral position, the traction suture is removed, and satisfactory intraocular pressure is confirmed by palpation. Results No complications arose during the procedure. Postoperatively, the patient had subconjunctival hemorrhage, injection, and mild pain that decreased over the following week. Prednisolone acetate drops were applied six times daily to prevent inflammation and moxifloxacin drops were applied four times daily to prevent infection. At the three-month follow up, the eye was quiet and intraocular pressure was measured to be 9 mmHg. Conclusion Implantation of an Ahmed glaucoma tube shunt is a safe procedure that can effectively treat various subtypes of glaucoma with sub-optimally controlled intraocular pressure despite maximum medical therapy.

Partial Penectomy due to Penile Calciphylaxis
videoPartial penectomy is the surgical standard of care for invasive tumors of the mid to distal penis, but is utilized in cases of distal penile calciphylaxis due to pain. Partial Penectomy is advantageous compared to a total penectomy, as the patient is able to urinate in the standing position. A 51-year-old man on dialysis for end stage renal disease presented to the emergency department with pain that was increasing in severity for over a month at the glans of the penis. On examination, the glans of the penis was firm with gangrenous necrosis extending distal to the corona, and the urethral meatus was not identified due to the extensive scarring. A clinical diagnosis of penile calciphylaxis was determined and a Partial Penectomy was subsequently performed. Calciphylaxis is a rare life-threatening systemic disease in patients with end stage renal disease due to medial calcification and fibrosis of blood vessels leading to infection and gangrene. The prognosis for penile calciphylaxis tends to be poor with an overall mortality of 64% with a mean time to death of 2.5 months.

Medial Orbital Dermoid Cyst Removal
videoDermoid cysts are the most common orbital tumor in childhood. It is a developmental benign choristoma, arising from ectodermal sequestration along the lines of embryonic fusion of mesodermal processes. It is lined by keratinized stratified squamous epithelium and expands slowly due to constant desquamation and dermal glandular elements. They are usually smooth, painless, mobile, or partially mobile lesions mostly present at the fronto-zygomatic suture with proptosis, displacement, ptosis, or diplopia, depending on depth and extent1. Although lateral orbital dermoid cysts are common, medial orbital dermoid cysts are rare2. Our patient had a right medial orbital congenital dermoid cyst since birth. At the presentation, the patient was 2 years old. On CT, the cyst measured 5 mm at the upper lid/medial canthus of the right orbit with subtle bone remodeling. He had a mildly clogged tear duct on the left but was otherwise asymptomatic. The decision was made to surgically remove the dermoid cyst. In this video, we present a case of removal of a medial orbital dermoid cyst in a 2-year-old patient. An incision was planned directly over the lesion. It was marked following the natural skin tension lines of the face to give the most natural esthetic appearance. A small amount of Local anesthetic (0.5 ml of Lidocaine and Epinephrine) was injected under the skin to promote hemostasis and postoperative pain control. A continuous Incision was made with a #15 blade on the skin. Westcott scissors were used to dissect further through the subcutaneous tissue to expose the cyst and slowly dissect it from the normal tissue surrounding it. Extra care was made to protect the integrity and avoid the rupture of the cyst. After the entire cyst was freed from the surrounding tissue, it was carefully removed from its attachments to the periosteum using Westcott scissors. The incision was closed in a two-layer fashion. The deeper layer was closed by 6.0 Vicryl in a vertical mattress fashion with 2 interrupted sutures. Next, wound edge eversion was achieved by placing two interrupted, superficial 5.0 fast-absorbing gut sutures. This will minimize the scar appearance. Dermabond was applied next and the sutures were protected by a small piece of Tegaderm. This will be left in place until it spontaneously falls off.

A Pediatric Case of Levator Palpebrae Resection
videoIn this video, we present a case of levator palpebrae resection in an 8-year-old patient with right eye ptosis. In the pre-op photo, significant ptosis of the right eye can be appreciated. An incision was planned along the lid crease. 0.1 ml of 1: 100,000 epinephrine was injected. An incision was made by electro-cautery along the lid through the skin and orbicularis. Westcott scissors were used to further dissect horizontally. The septum was identified and opened. The preaponeurotic fat was identified and lifted, and the levator aponeurosis was identified. The levator was then tagged with two 6.0 Vicryle sutures, and isolated from surrounding tissues. Next, three6-0 Mersilene sutures were run from the upper tarsus to the levator. They are tightened with releasable notes. The lid elevation and contour were evaluated and adjustments were made until contour and height were equal and appropriate. The temporary surgical knots were transitioned into permanent surgical knots. Approximately 14 mm of excess levator was then excised. Next, three lid crease formation sutures were placed using 6-0 Vicryl. These were attached to the subcu-skin and levator to recreate the upper eyelid crease. Skin closure was performed with 6-0 fast-absorbing gut sutures. In this one-week post-op photo, the ptosis of his right eye was improved. Thank you for watching!

videoComplete repair of Tetralogy of Fallot with a transannular patch. The patient is placed on cardiopulmonary bypass in the standard fashion. An incision in made into the free wall of the right ventricle and the septal defect is exposed. A non-autologous CorMatrix patch is placed with prolene suture in a running fashion to repair the septal defect. An additional patch is used to repair the right ventricular outflow tract with a similar running suture. The patient was removed from cardiopulmonary bypass and extubated in the operating room.
Branchial Cleft Cyst Excision
videoBranchial cleft cysts are a benign anomaly caused by incomplete obliteration of a primordial branchial cleft. They typically appear in childhood or adolescence, but can appear at any age. They present as a non-tender, fluctuant mass following an upper respiratory infection, most commonly at the anterior border of the sternocleidomastoid muscle. These lesions are thought to originate during the 4th week of gestation when the branchial arches fail to fuse. The second branchial cleft is the most common site (95%) and cysts from in this distribution can affect cranial nerves VII, IX, and XII.
Pediatric Lumbar Epidural Catheter Placement via the Landmark Technique.
videoThis video demonstrates an epidural catheter placement on a 2-year-old, 12kg male patient presenting for left hip osteotomy. His past medical history was remarkable for congenital heart defects, bilateral congenital hip dislocations, and a sacral dimple which is sometimes associated with neurologic spinal canal abnormalities. In this case, no neurologic anatomical abnormalities were demonstrated on the neonatal spine ultrasound. The patient was placed in a left lateral decubitus position. Using anatomical landmarks like Tuffier’s line or the intercristal line corresponding to L4-L5 level, the target level for needle placement was identified and marked. The patient’s skin was sterilized and draped under sterile conditions. An 18-gauge, 5 cm length Tuohy needle was used to encounter the epidural space. A general guideline for the depth to the epidural space from the skin is approximately 1mm/kg of body weight¹. Subsequently, a 20-gauge catheter was placed through the needle to a depth of 4.5 cm at the level of the skin. Negative aspiration of blood or CSF was confirmed. A test dose was calculated at 0.5 mcg/kg epinephrine or 0.1ml/kg of lidocaine 1.5% with epinephrine 1:200,000. In this case, a 1.2 mL test dose of lidocaine 1.5% with epinephrine 1:200,000 was given without any observed cardiovascular changes (e.g. ≥ 25% increase or decrease in T wave amplitude, HR increase ≥ 10 bpm, or SBP increase ≥ 15 mmHg)¹. Finally, the catheter was secured to the back of the patient. Parental consent was obtained for the publication of this video.
