Airway Equipment Stephen Estime, MD; Abdullah Hasan Pratt, MD; Nicholas Ludmer, MD UChicago Medicine
Airway trauma is a critical and potentially life-threatening condition, and timely diagnosis and management is imperative for patient survival, as concomitant injuries and nonspecific symptoms may otherwise lead to fatal outcomes. Efficient airway management is paramount to addressing airway trauma, necessitating a comprehensive approach involving timely diagnosis, appropriate interventions, and the use of specialized equipment to ensure optimal patient outcomes.
Prompt and efficient management not only ensures the patient’s immediate survival but also plays a pivotal role in minimizing the impact on respiratory function and overall quality of life. The main objective is to establish a secure and patent airway, enabling efficient ventilation and later surgical repair. This video delivers a thorough and detailed exposition of the equipment utilized in airway management.
Robotic surgery as an approach for bariatric surgery has been a subject of debate for at least two decades since the platform passed FDA approval. One could argue that the exponential growth of robotics in surgery could end such a debate. The robotic platform offers several advantages that are always advertised, but in the morbidly obese population it offers an added advantage. It is arguable that with the advanced ergonomics, superior visual tools, and wristed instruments the robotic platform is superior in its offerings to the surgeon and enables a wider variety of surgeons with variable skill set to adopt minimally-invasive surgery (MIS), especially in bariatrics.
The Sleeve gastrectomy is technically a straightforward procedure to perform and is easier to learn for trainees and novel surgeons. It could, however, pose some challenges especially in patients with increased BMI, which is a huge advantage for the robotic platform as it allows easier exposure and comfort during the operation.
DCR and Nasolacrimal System (Cadaver) Prithwijit Roychowdhury, BS1; C. Scott Brown, MD2; Matthew D. Ellison, MD2 1University of Massachusetts Medical School 2 Department of Otolaryngology, Duke University
Nasolacrimal duct obstruction (NDO) is the most common disorder of the lacrimal system that affects patients of every age and results in excessive tearing (epiphora) and if untreated, painful infection (dacryocystitis). When NDO symptoms progress and can no longer be managed with conservative measures, endoscopic dacryocystorhinostomy (DCR) is indicated.
In this case, DCR exploration of the nasolacrimal anatomy is performed on a cadaver. The typical presentation of NDO is epiphora but the presence of painful swelling of the medial canthus and mucoid or purulent discharge may indicate the presence of dacryocystitis. The approach presented here involves the creation of a mucosal flap and subsequent use of the DCR drill to expose the nasolacrimal duct anatomy.
Minimally invasive direct coronary artery bypass (MIDCAB) utilizes a small (4–5 cm) left anterior thoracotomy incision for direct visualization of the diseased coronary artery on the anterior wall of the left ventricle without the use of cardiopulmonary bypass (CPB).
This article describes the basics of the MIDCAB surgery, emphasizing both the left anterior thoracotomy for the harvest of LIMA and direct anastomosis on a beating heart without CPB. This procedure is done on a 72-year-old patient who had significant long LAD stenosis and presented with effort angina. Following a multidisciplinary “heart team” conference, he underwent a successful MIDCAB and was discharged home on postoperative day 4.
The application of minimally-invasive approaches in otologic surgery, including the management of middle ear tumors like glomus tympanicum tumors, represents a promising advancement in the field, potentially improving surgical outcomes and patient recovery. In this article, a patient with pulsatile tinnitus is found to have a glomus tympanicum tumor of the right ear. Calhoun Cunningham III, MD performs a transcanal resection of the mass using the KTP laser.
This video article demonstrate surgical correction of a severe hand deformity in a teenage girl with spastic hemiplegia. This patient has a non-functioning hand due to severe spasticity. Correction of the deformity is indicated primarily to facilitate hygiene and improve the position of the fingers. In some patients with volitional control, a certain degree of prehension may be achieved. The basic principles of deformity correction include differential sectioning of sublimis and profundus tendons followed by repair in a lengthened position. The first web contracture is released by muscular release and a skin Z-plasty.
Tracheomalacia is a rare congenital condition that results in incompetence of the trachea, the main airway, leading to collapse of the trachea during respiration. Most often this is due to inadequate bone formation in the trachea, and this causes it to be dynamically collapsed, which can result in breathing difficulties for the child. Upper respiratory infections can also be more common. While most cases of tracheomalacia resolve by 18 to 24 months of age, a small percentage either continue or cause such severe breathing or feeding issues that surgical intervention is warranted. In cases where the innominate artery is the cause of compression of the weakened trachea, an aortopexy to elevate the vessel up to the sternum and away from the trachea is performed.
Shoulder Arthroscopy (Cadaver) Patrick Vavken, MD1; Sabah Ali2 1Smith and Nephew Endoscopy Laboratory 2University of Central Florida College of Medicine
Shoulder arthroscopy is one of the most common procedures performed in orthopaedic surgery. It can be utilized to identify various pathologies including rotator cuff tears, degenerative arthritis, subacromial impingement, and proximal humeral fractures. With continued advancement in arthroscopy, patients benefit from smaller incisions, reduced risk of postoperative complications, and faster recovery compared to open surgery.
Shoulder arthroscopy is performed either in the lateral decubitus position or in the beach chair position (BCP) as seen in this video. The BCP provides greater benefits such as decreased neovascularization during portal placement, fewer cases of neuropathies, and reduced surgical time. In addition to position, there are various portals used in shoulder arthroscopy, with the posterior portal being the most common and used in this video. Complication rates from shoulder arthroscopy are low but include shoulder stiffness, iatrogenic tendon injury, and vascular injury. Therefore, proper patient selection, patient positioning, and appropriate portal selection are essential for successful shoulder arthroscopy. This article discusses shoulder arthroscopy and demonstrates the technique on a cadaver shoulder.
Parotid dissection is a delicate surgical procedure that requires a deep understanding of the relevant anatomy and a careful approach to ensure the preservation of critical structures, particularly the facial nerve. The comprehensive overview provided in this video is a valuable resource for understanding the step-by-step process of parotid dissection. The detailed narration and visual references help to reinforce the importance of accurate identification and preservation of the facial nerve, as well as the other key anatomical structures involved in the procedure. This information is crucial for surgeons in training, as well as for experienced practitioners, to ensure the safe and effective removal of parotid gland tumors while minimizing the risk of complications.
Intraventricular Tumor Resection Tyler N. Adams1; Marcus Czabanka, MD2 1Louisiana State University School of Medicine 2Charite Hospital Berlin
This is a case of a 49-year-old patient who presented with persistent headaches with no focal neurologic deficit. An MRI was performed which revealed an intraventricular tumor. The lesion was seen entering the third ventricle and potentially compressing both foramina of Monro. This was further confirmed through coronal reconstruction. The proposed method for tumor removal is an interhemispheric, transcallosal approach.
Central nervous system (CNS) tumors, such as this, are uncommon neoplasms that often present with symptoms like headache, nausea, vomiting, ataxia, vertigo, and papilledema. There is also the possibility of hydrocephalus, as the tumor can obstruct cerebrospinal fluid (CSF) outflow, and the development of seizures. These tumors often grow slowly and can be managed with surgical resection, chemotherapy, and/or stereotactic radiosurgery. For intraventricular tumor resection, the surgical approach can vary based on the tumor location, experience, and preference of the surgeon.
