Laryngomalacia is the most common laryngeal anomaly affecting newborns. Patient's with severe disease should be considered for supraglottoplasty. It classically presents in a newborn with high-pitched inspiratory stridor that worsens with exertion, supine-positioning, and feeding. It is characterized by anatomic and physiologic abnormalities including shortened aryepiglottic (AE) folds, small, tightly curled epiglottis, redundant soft tissue overlying the cuneiform or accessory cartilages and reduced laryngeal tone. Any combination of these may present with laryngomalacia. Most cases are mild and resolve with observation or medical therapy. Steps: 1. Laser precautions are taken to protect patient and personnel. 2. Spontaneous ventilation 3. Suspension laryngoscopy is performed with adequate visualization of the larynx. 4. The operating telescope or microscope is used for visualization. The CO2 laser is tested. 5. First, division of the AE folds is performed. 6. Next, redundant mucosa and tissue overlying the accessory cartilages is ablated.

Contributors: Vincent Couloigner We describe the excision of a nasal encephalocele obstructing the left nasal fossa with an anterior subcutaneous portion deforming the nasal pyramid in a four-year-old girl using endoscopic surgery combined to a Rethi approach. The anterior skull base defect was reconstructed using autologous conchal cartilage and temporal fascia. Editor Recruited By: Sanjay Parikh, MD, FACS DOI: http://dx.doi.org/10.17797/udewjr2ge7

Contributor: Gresham T. Richter, MD (Arkansas Children's Hospital) Pressure equalization tube placement is one of the most common procedures in the pediatric population. This video demonstrates the surgeon's view of the right ear through the operative microscope. Indications: recurrent otitis media with effusion, chronic otitis media with effusion (>3 months duration), speech/language delay secondary to otitis. Instruments: operative microscope, ear speculum, ear curette, myringotomy knife, suction tube, pressure equalization tube Procedure Steps: 1. Speculum inserted into external auditory canal 2. Cerumen removed with the curette (not shown in video) 3. Myringotomy performed on anterior-inferior quadrant of tympanic membrane 4. Fluid aspirated with suction tube 5. Pressure equalization tube (PET) inserted and secured 6. Antibiotic otic drops applied 7. Cotton dressing applied Recommended Resource: Lambert E, Roy S. Otitis media and ear tubes.

Contributors: Umamaheshwar Duvvuri (University of Pittsburgh Medical Center) A DaVinci Robot is used to dock in with a 30 degree up telescope.The oral cavity is exposed using a FK retractor or a modified McIvor mouth gag( one with a flat blade). Robotic 5 mm Maryland forceps and 5 mm monopolar diathermy forceps is used. After getting a good exposure of the laryngeal cleft the diathermy at a setting of 4-5 watts is used to make the incision.and using the maryland forceps the laryngeal and esophageal flaps are created.A 5.0 PDS suture with a P2 tapered needle is used.The apex of the esophageal flap is first closed with suturing it.After this the apex of the laryngeal surface is closed.For a laryngeal cleft repair 2-4 sutures are required to obtain a closure. The sutures on the laryngeal surface are buried.The patient is kept intubated for a day or two to avoid excess movement of larynx. Pre and post operative treatment of reflux is important for healing.

Introduction Muscle recession is a type of strabismus surgical procedure that aims to weaken an extraocular muscle by adjusting its insertion posteriorly closer to its origin. The patient is a 14-year-old with dissociated vertical deviation, which can be corrected with recession of the superior rectus muscle. Methods A conjunctival incision is made in the fornix. Tenon's capsule is dissected to expose the superior rectus muscle. The superior rectus muscle is isolated using a Stevens tenotomy hook followed by a Jameson muscle hook. After the remaining Tenon's attachments are cleared, the muscle is secured at both poles with a double-armed 6-0 VicrylTM suture and double-locking bites. The muscle is then disinserted from the sclera with Manson-Aebli scissors. A caliper is used to mark the predetermined distance of muscle reinsertion. Next, the muscle is reattached to the sclera with partial thickness bites and then tied down to its new location. The conjunctival incision is closed with 6-0 plain gut sutures. Results No complications arose during the procedure. Postoperatively, the patient had subconjunctival hemorrhage, injection, and pain that decreased over the following week. Neomycin-polymyxin-dexamethasone drops were applied daily to prevent infection and inflammation. At the three-month follow up, the redness had resolved. The dissociated vertical deviation had improved. Conclusion Superior rectus recession is a safe procedure that can effectively treat vertical strabismus.
