The submandibular approach, also known as the Risdon approach, is a well-established extraoral surgical technique employed for the treatment of complex mandibular fractures and pathologies. Despite the increasing popularity of intraoral approaches for open reduction and internal fixation, the submandibular approach remains a valuable option in the arsenal of maxillofacial surgeons. This approach offers several advantages, including superior access and visualization of the mandibular body and angle, facilitating better manipulation and reduction of fracture fragments. Furthermore, the submandibular approach enables direct access to the submandibular gland, facilitating its management in cases of pathology or injury. By providing a comprehensive understanding of this technique through cadaveric exploration, this video aims to contribute to the training and education of maxillofacial surgeons, ultimately enhancing patient care and outcomes.
Bilateral axillo-breast approach (BABA) is a contemporary technique for remote-access thyroidectomy. BABA robotic thyroidectomy (RT) offers a number of benefits over other remote-access thyroidectomy techniques, such as provision of a three-dimensional symmetric view of bilateral thyroid lobes and optimal visualization of important anatomical landmarks, including the recurrent laryngeal nerve (RLN), thyroidal vessels, parathyroid glands, and the trachea.
This educational video is a thorough demonstration of BABA RT performed on a young female patient diagnosed with a left-sided thyroid nodule in her early thirties. The thyroid fine needle aspiration biopsy of the 4-cm nodule was indeterminate. Additional molecular testing of the specimen had revealed one of the mutations associated with thyroid cancer. Therefore, a diagnostic thyroid lobectomy was planned. The patient had expressed a strong desire to avoid an obvious neck scar, and therefore, the BABA RT was offered.
Minor lower extremity amputations typically involve either toe or ray resections. The first ray is an essential component in the normal anatomy and biomechanics of the foot. By definition, the first ray consists of the hallux and the first metatarsal. The surgical procedure discussed in this educational video is a left first toe ray amputation on a cadaver. Toe amputation is a significant predictor of future limb loss. Ray amputation appears to be preferred over finger amputation in selected cases. However, the literature does not provide precise indications on when to consider a ray over a toe amputation. The choice is therefore left to the operating surgeon, based on their clinical expertise and the patient’s conditions and expectations, taking into account the underlying pathology.
Open Proctocolectomy for Hirschsprung’s Disease Mudassir Shah Akhter, MD1; Marcus Lester R. Suntay, MD, FPCS, FPSPS, FPALES2 1Oregon Health and Science University 2Philippine Children’s Medical Center
Hirschsprung’s disease is the main genetic cause of functional intestinal obstruction. Most cases are diagnosed in the first few months of life given classical presentation and ease of testing with rectal suction biopsy. The disease is due to the absence of enteric ganglion cells in the distal colon that results in functional constipation. Resection of the affected segment and bringing the normal bowel close to the anus has been the mainstay of treatment. Due to advances in surgical treatment over the past decades, a significant reduction in morbidity and mortality has been observed, and the previously multistage procedure can now be completed in one stage, as presented here.
Primary leiomyosarcomas of the inferior vena cava (IVC) are rare tumors with complex anatomical relationships. Surgical resection remains the primary approach for management, with selective use of preoperative radiation and chemotherapy. Given the propensity for local invasion of these tumors, radical resection of surrounding structures is often required.
This article describes the presentation, work-up, operative management, and outcomes of these lesions through the case of a patient with a tumor involving the middle segment of the IVC. Given the extent of involvement, IVC resection with en bloc right nephrectomy, right adrenalectomy, and partial left renal vein resection was performed with vascular reconstruction using a prosthetic graft. With appropriate preoperative planning and a well-coordinated multidisciplinary approach, aggressive surgical resection can be safely performed and patients can benefit from favorable long-term survival.
The primary survey of every trauma patient begins with ABC: airway, breathing, circulation. If the patient is deemed to require airway management, endotracheal intubation may be performed utilizing rapid sequence intubation (RSI). In RSI, an induction agent and a rapid-acting neuromuscular blocking agent (NMBA or paralytic) are administered and intubation is performed as soon as unconsciousness and paralysis are achieved. Trauma patients may require intubation for a number of reasons. This video review focuses on the pharmacology, dosing, and other considerations for use of common medications for pretreatment, paralysis with induction, and post-intubation management in trauma patients.
A hemothorax is a collection of blood within the pleural cavity. Blood can accumulate within this space as a sequelae of chest trauma (penetrating or blunt), iatrogenic injury (e.g., vascular access injuries), or spontaneously (e.g., due to malignancy). To treat the condition, a chest tube is inserted into the thoracic cavity on the affected side of the body. In addition to evacuating blood from the pleural cavity, a chest tube can also be used to treat pneumothorax (air in the pleural space) and pleural effusion (e.g., empyema or chylothorax), and to insert medications into the pleural space. Depending on the specific pathology, a tube or catheter may be utilized.
Central venous access is a crucial aspect in the management of patients requiring long-term therapies, particularly surgical patients. These therapies include the administration of therapeutic agents, fluid administration, antibiotic therapy, parenteral nutrition, etc. The procedure involves the placement of a catheter into a venous great vessel. Three main sites for central venous access are: internal jugular vein, common femoral vein, and subclavian veins.
In resource-constrained settings, healthcare professionals must rely on their clinical practice and proficiency in performing procedures without the aid of advanced imaging modalities. One such procedure is the infraclavicular subclavian vein cannulation, which can be performed without ultrasonographic guidance, providing a reliable means of obtaining central venous access. Here, this is demonstrated on a pediatric preoperative patient during a surgical mission in Honduras.
Coronal Approach (Cadaver) Felix L. Hong, DDS; Mark R. Rowan, MD, DDS; R. John Tannyhill, III, MD, DDS, FACS Harvard Medical School
For treatment of facial trauma such as a frontal sinus fracture, orbital fractures, or zygoma fractures, the coronal or bi-temporal approach is used. The approach can also be used for superficial temporal artery biopsy. This approach exposes the anterior cranial vault, forehead, and upper and middle regions of the facial skeleton including the zygomatic arch. It provides access to these areas with minimal complications and cosmetically acceptable hidden scars. The subperiosteal or subgaleal planes are commonly used for coronal flap dissection. This article presents a demonstration of the coronal approach to exposing the upper or middle facial skeleton in a cadaver.
Open Distal Gastrectomy Andrea L. Merrill, MD; John T. Mullen, MD Massachusetts General Hospital
A complete margin-negative (R0) resection remains the only potentially curative treatment for gastric adenocarcinoma. The choice of operation depends on the location of the tumor as well as the stage of disease. This patient presented with symptomatic anemia, and workup demonstrated gastritis and a small tumor in the distal stomach. Biopsies confirmed adenocarcinoma, and an endoscopic ultrasound (EUS) staged this tumor as T2 N0. Staging scans showed no evidence of distant metastatic disease. Given that this patient had a relatively early stage tumor, they elected to proceed with upfront surgery, which in this case entailed a distal gastrectomy. This video shows an experienced gastric surgeon’s technique for performing an open distal gastrectomy with an “extended” D1 lymph node dissection.
