Duke University School of Medicine

Functional endoscopic sinus surgery (FESS) is a minimally-invasive technique involving the use of an endoscope to visualize and access the paranasal sinuses, allowing for precise and targeted removal of diseased tissue. The cadaveric video on FESS presented here offers a detailed and comprehensive guide to maxillary, ethmoid, and sphenoid sinus dissection. The step-by-step approach, coupled with the emphasis on anatomical considerations, makes this video an essential resource for healthcare professionals involved in the management of sinonasal disorders.

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.

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.

Rotator cuff tears represent the vast majority of shoulder disorders treated by orthopaedic surgeons. From partial-thickness tears in overhead throwing athletes to full-thickness tears in the elderly, the prevalence of rotator cuff tears continues to increase over time. While some cases are asymptomatic, most patients with rotator cuff tears report shoulder pain, limited range of motion, and nighttime pain with difficulty sleeping on the affected shoulder. When nonsurgical treatment is insufficient in relieving the symptoms, arthroscopic rotator cuff repair becomes a viable option for many patients.

This is the case of a rotator cuff repair of a full-thickness tear that extends into the infraspinatus on a cadaver shoulder in the beach chair position. The tear was repaired by placing an anchor, retrieving and passing three suture arms, and tying the suture. This article outlines the natural history, preoperative care, intraoperative technique, and postoperative considerations of rotator cuff repairs.

Ulnar nerve transposition is a surgical procedure performed to treat ulnar nerve compression of the elbow, also known as cubital tunnel syndrome. This procedure is utilized after both non-operative management and in situ decompression fails, or if these procedures are deemed inappropriate based on patient pathology or ulnar nerve instability.

Transposition of the ulnar nerve involves not only decompression of the nerve but also its anterior repositioning to reduce compression and irritation while maintaining nerve integrity. This video demonstrates, on a cadaver arm, the operative technique for performing an ulnar nerve transposition using either a subcutaneous or a submuscular technique.

Cadaveric dissections of the temporal bone are a critical part of learning otologic surgery in residency. Dr. Scott Brown, neurotology fellow at the University of Miami, performs a step-by-step dissection of the temporal bone. He outlines key anatomical structures and describes safe and efficient techniques for these procedures.

Cubital tunnel syndrome is a condition that affects the ulnar nerve as it crosses the medial elbow through the retrocondylar groove. It is the second most common compressive neuropathy, causing tingling and numbness in the ring and small fingers. In advanced cases of symptomatic cubital tunnel syndrome, weakness, altered dexterity, and atrophy of the intrinsic muscles of the hand may develop. Cubital tunnel syndrome can be treated with either a cubital tunnel release or an ulnar transposition. In this case, the former is demonstrated on a cadaveric arm using the mini-open technique.

Carpal Tunnel Release (Cadaver)

Carpal tunnel syndrome (CTS) is the most common peripheral compression neuropathy and results in symptoms of numbness and paresthesia in the thumb, index finger, middle finger, and half of the ring finger. When CTS symptoms progress and can no longer be managed with nonoperative measures, carpal tunnel release (CTR) surgery is indicated.

In this case, Dr. Asif Ilyas at the Rothman Institute performs CTR surgery on a cadaveric arm via the mini-open CTR technique. A 2-cm longitudinal incision was placed directly over the carpal tunnel, the transverse carpal ligament was exposed and then released, and the wound was closed. Patients are typically sent home with instructions to use their hand immediately postoperatively, while avoiding strenuous use until the incision has healed. Splinting and therapy are not required postoperatively.
