We report the case of a laryngectomized patient with an enlarged tracheoesophageal puncture (TEP) that is refractory to standard treatments and culminating in life-threatening recurrent dislodgement and aspiration of custom fabricated dual extra-large flange voice prostheses (VP). The fabrication and use of a novel intraluminal prosthetic device to prevent dislodgement, lessen aspiration, and preserve TE voice is described. A custom device insetting a commercial VP into the posterior wall of a LaryTube (coined "inset-VP") was devised with the primary goal of eliminating chronic VP dislodgement and lessening aspiration while maintaining TE voice...

Background Total hip arthroplasty (THA) is effective in the treatment of hip osteoarthritis. Radiographic evaluation, standard in THA planning, is sufficient in examining hip anatomy, although it may not precisely assess bone quality. A routinely implemented method in bone quality assessment is densitometry. The technique allows for a measurement of bone mineral density (BMD). Methodology In the study, we included 26 participants who qualified for THA. All the patients were preoperatively examined with radiographs and densitometry of the affected hip...

INTRODUCTION: Ruptured abdominal aortic aneurysms (AAAs) pose an immediate threat for patient's life and endovascular repair (EVAR) is currently the preferred treatment modality in the presence of suitable anatomy. This is determined based on the requirements of each endograft as described in the instructions for use (IFU). The new ALTO system (Endologix, Irvin, CA, U.S.A.), can accommodate a great range of anatomies such as short necks and/or narrow access, but its unique design requires specific technical modifications during treatment of ruptured AAAs...

Gross anatomy laboratories frequently utilize dissection or prosection formats within medical curricula. Practical examination scores are consistent across the formats, yet these examinations assessed larger anatomical structures. In contrast, a single report noted improved scores when prosection was used in the hand and foot regions, areas that are more difficult to dissect. The incorporation of prosected donors within "Head and Neck" laboratories provided an opportunity to further characterize the impact of prosection in a structurally complex area...

BACKGROUND: Proton therapy is a form of radiotherapy commonly used to treat various cancers. Due to its high conformality, minor variations in patient anatomy can lead to significant alterations in dose distribution, making adaptation crucial. While cone-beam computed tomography (CBCT) is a well-established technique for adaptive radiation therapy (ART), it cannot be directly used for adaptive proton therapy (APT) treatments because the stopping power ratio (SPR) cannot be estimated from CBCT images...

The brachial plexus consists of nerves that supply the upper limb and some nerves of the back, torso, and neck. It is formed by the ventral rami of C5 to T1 (in some cases, C4 or T2 also contribute). The anterior rami of the spinal nerves unite to the roots, trunks, divisions, cords, and terminal branches that innervate muscles and skin. An example is associated with terminal branches of the long nerves. Knowledge of this variation is necessary for enabling surgeons, orthopedists, and neurologists to avoid injury during surgical exploration in the arm or axilla region, and for achieving correct diagnoses, because such variability can evoke nonspecific responses...

Cervical spondylotic myelopathy (CSM) is defined as compression of the spinal cord in the neck, resulting in problems with fine motor skills, hand numbness, pain or stiffness of the neck, and difficulty walking due to loss of balance. Brachial plexus (BP) neuropathies arise due to compression to any distal branches arising from C5-T1, whereas cervical radiculopathy involves compression at the nerve root in the neck. Such conditions can present with variable degrees of musculoskeletal pain, weakness, sensory changes, and reflex changes...

Among the various anatomical landmarks during neck dissection, digastric muscle is one of the most important. It is well known that all important blood vessels in neck lies deep to digastric. Thus, it acts as a safety landmark during neck dissection. In this article we describe a variation in vascular anatomy with relation to posterior belly of digastric that has not been reported so far during live surgery. Surgeon performing neck dissection should have a detailed knowledge of anatomy and infrequent anatomical variation...

BACKGROUND: Micro-focused ultrasound with visualization (MFU-V) delivers energy to specific soft tissue layers beneath the epidermis with the ability to lift and tighten the lower face and neck.  Objective: To determine the efficacy of microfocused ultrasound with visualization (MFU-V) using a standard treatment line protocol versus a customized treatment line protocol based on the patient's unique anatomy targeting the superficial muscular aponeurotic system and fibrous septae for lifting and tightening of the lower face and neck...

<b/>The intracranial segment of the internal carotid artery located inside the skeleton structure of skull base or inside the skull has clear anatomical landmarks and fixed anatomical structure. However, the parapharyngeal segment of the internal carotid artery located outside the cranial is surrounded by soft tissues, lacks clear and recognizable anatomical landmarks and sometimes has anatomical variation, which is closely related to transnasal endoscopic surgery. Intraoperative accidental injury can lead to serious complications or even death...

The free medial sural artery perforator (MSAP) flap is a recently popularized flap. It has evolved from a composite myocutaneous flap to a pedicled perforator flap for lower limb reconstruction. It is also a versatile free perforator flap for extremity and head and neck reconstruction. The diversity of the flap designs with options for harvest of non-vascularized grafts enhances the versatility for hand and upper limb reconstruction. The adjunctive use of endoscopy and indocyanine green fluorescence imaging studies can assist and demystify the flap anatomy...

PURPOSE: The head and neck cancer (HNC) literature is rife with reports of differences in planned versus actual radiation doses to the parotid gland (PG) due to changes in anatomy during the course of radiation therapy. We prospectively studied and quantified changes in planned and delivered doses due to weight loss and changes in lateral neck dimensions. METHODS AND MATERIALS: Sixty patients were enrolled in this prospective non-randomized observational study. The inclusion criterion was having a newly diagnosed, histologically proven squamous cell carcinoma of HNC...

The individual Geoffroy's side-necked turtle, Phrynops cf. P. geoffroanus, was diagnosed postmortem with osteosarcoma associated with the forelimb through morphological and histological analysis. Osteosarcoma stands as the most prevalent primary malignant bone tumor in tetrapods. The tumor presents itself as a large mass in the distal epiphysis, characterized by spicular outgrowths and a rugose external texture. Histologically, the afflicted humerus displayed a high degree of vascularity and exhibited an extensive bone resorption process involving the medullary and endosteal regions...

The aged neck is the most common motivator for patients seeking facial rejuvenation. Unlike the deflated midface, surgical treatment is still the gold standard for optimal outcomes. It is our view that the majority etiology of both the aged neck and deflated midface is gravity's effects on the superficial soft tissue envelope, leading to soft tissue redundancy. It is also our view that the deep-plane rhytidectomy is supported by anatomy, embryology, and clinical evidence as the best methodology to treat soft tissue redundancy without producing the aesthetic and longevity issues associated with superficial musculoaponeurotic system techniques...

BACKGROUND: Artificial intelligence models can learn from medical literature and clinical cases and generate answers that rival human experts. However, challenges remain in the analysis of complex data containing images and diagrams. OBJECTIVE: This study aims to assess the answering capabilities and accuracy of ChatGPT-4 Vision (GPT-4V) for a set of 100 questions, including image-based questions, from the 2023 otolaryngology board certification examination. METHODS: Answers to 100 questions from the 2023 otolaryngology board certification examination, including image-based questions, were generated using GPT-4V...

Technological developments and the pandemic have popularized the distance learning model at universities. In this educational model, students spend more time in front of screens, and screen-related health conditions have become important. This cross-sectional study of 177 undergraduate students was designed to investigate the effect of block and traditional scheduling in online distance education (ODE) on their musculoskeletal pain and to investigate their perceptions of block scheduling. A two-stage method was used: a quantitative design to compare pain levels, and a qualitative design to determine the students' perceptions of block scheduling using an online survey...

Osteosarcomas are rare and highly malignant bone tumours which are composed of malignant mesenchymal cells producing osteoid or immature bone. Maxillary osteosarcomas are rare tumours accounting for less than 1% of head and neck malignancies. Aggressive surgical resection is the main modality of treatment with good reconstruction. Due to the complex anatomy and location of maxilla as well as its proximity to the skull, resection with negative margins is always a challenge and so is the reconstruction so as to reduce the morbidity of the patient and to also give a good functional and cosmetic outcome...

PURPOSE: The superficial venous system (SVS) of the neck receives blood from the face and oral cavity. The SVS comprises the anterior jugular vein (AJV), external jugular vein (EJV), and facial vein (FV). Comprehensive knowledge of the normal anatomy and potential variations in the venous system is valuable in surgical and radiological procedures. This study aimed to update the anatomic knowledge of the SVS using a radiographic approach, which is a beneficial data source in clinical practice...

Airway management is a vital part of anesthesia practices, intensive care units, and emergency departments, and a proper pre-operative assessment can guide clinicians' plans for securing an airway. Complex airway assessment has recently been at the forefront of anesthesia research, with a substantial increase in annual publications during the last 20 years. In this paper, we provide an extensive overview of the literature connected with pre-operative airway evaluation procedures, ranging from essential bedside physical examinations to advanced imaging techniques such as ultrasound (US), radiography, computed tomography (CT), and magnetic resonance imaging (MRI)...
