Background: The upper third of the larynx shares a wall with the pharynx, the laryngopharyngeal wall. This anatomic structure is common to both organs and is often the source of epidermoid carcinomas. These carcinomas are more frequent in subjects who ingest large amounts of alcohol. The purpose of this study is to describe the indications, contraindications, technical errors and surgical technique of the supracricoid hemilaryngopharyngectomy and horizontal supraglottic laryngectomy.
Discussion: These tumors are usually bulky, respect laryngeal function and are limited to this anatomic structure. Laryngeal mobility is respected through advanced stages of the disease. Because tumors originating in this region are highly lymphophilic (presenting occult nodal metastasis in up to 45%), both techniques should be accompanied by cervical lymph node dissection, generally bilateral, and including at least levels II to IV. The presence of lymph node metastases is not an absolute contraindication for these procedures.
Conclusions: We describe two surgical techniques designed to obtain adequate cancer control, preserving the natural functions of swallowing, speech and ventilation in patients with tumors arising in the supraglottic region and the region between the larynx and hypopharynx.

Purpose: To investigate the anatomical variations and measure the distances between surgically relevant structures in the maxilla associated with Le Fort I osteotomy in patients with maxillary canting using cone beam computed tomography (CBCT).
Methods: CBCT scans of 63 patients (21 males and 42 females) with maxillary canting who were indicated for orthognathic surgical planning were retrospectively investigated and analyzed. The distances of the relevant anatomical structures, including the descending palatine artery, pterygomaxillary junction, infraorbital foramen, and nasolacrimal duct opening, were measured with the key anatomical landmarks to evaluate their variations.

Anorectal fistulas remain one of the most challenging conditions in colorectal surgery and require precise anatomical knowledge for successful management. This comprehensive review synthesizes the current evidence on the anatomical foundations of fistula development and treatment, particularly focusing on the cryptoglandular hypothesis and its clinical implications. A systematic analysis of the recent literature has examined the relationship between anatomical structures and fistula formation, classification systems, diagnostic modalities, and therapeutic approaches.

Background: Sciatic scoliosis is attributed to non-structural scoliosis resulting from the irritation of spinal nerve roots. Although limited research has addressed the specific characteristics of sciatic scoliotic curve patterns, there is a lack of reported data on the pre- and post-radiographic outcomes of patients with sciatic scoliosis caused by lumbar disc herniation who have undergone full-endoscopic interlaminar discectomy (FEID).

Objectives: Utilizing a deep learning approach is an emerging trend to improve the efficiency of periodontitis diagnosis and classification. This study aimed to use an object detection model to automatically annotate the anatomic structure and subsequently classify the stages of radiographic bone loss (RBL).
Materials And Methods: In all, 558 panoramic radiographs were cropped to 7359 pieces of individual teeth.

Background: Adaptive radiotherapy (ART) can compensate for the dosimetric impact of anatomic change during radiotherapy of head-neck cancer (HNC) patients. However, implementing ART universally poses challenges in clinical workflow and resource allocation, given the variability in patient response and the constraints of available resources. Therefore, the prediction of anatomical change during radiotherapy for HNC patients is of importance to optimize patient clinical benefit and treatment resources.
