要旨

Objective:

This study aimed to investigate the effects of submental flap reconstruction during open horizontal partial laryngectomy (OPHL) on improving postoperative swallowing function.

Methods:

A total of 72 patients with supraglottic laryngeal cancer were retrospectively divided into 3 groups: group A, including patients (n=30) who underwent classic OPHL; group B, including patients (n=18) who underwent transoral laser microsurgery; and group C, including patients (n=24) who underwent OPHL with submental flap reconstruction. Swallowing function was assessed using the Water Swallow Test (WST) and the Chinese version of the MD Anderson Dysphagia Inventory (MDADI). Voice function was evaluated using the Chinese version of Voice Handicap Index-10, and the incidence of postoperative respiratory distress was recorded.

Results:

The WST revealed that group C had significantly superior swallowing function relative to groups A and B. Similarly, MDADI scores were significantly higher in the group C than those in groups A and B. No significant difference was identified in voice function among the 3 groups.

Conclusion:

Submental flap reconstruction during OPHL significantly improved postoperative swallowing function and reduced aspiration symptoms, making this technique a valuable surgical option that warrants further consideration.

Upper GI Series: Barium Swallow

Upper GI Series: Barium Swallow

The Barium Swallow Study, or a Barium Esophagogram, is a diagnostic imaging method used to visualize the upper gastrointestinal (GI) tract, including the esophagus, stomach, and small intestine. It employs barium sulfate, a radiopaque contrast material, to provide clear images of the upper digestive system, helping to identify abnormalities, diseases, or structural issues.
Purpose and Procedure
Patients undergoing this procedure ingest a liquid containing barium sulfate with a chalky...

Introduction to Horizontal Curves

Introduction to Horizontal Curves

Horizontal curves are essential in highway and railroad design, ensuring smooth and safe transitions between straight path segments, or tangents. These curves allow vehicles to maintain speed without abrupt changes, minimizing accidents and improving travel efficiency.A horizontal curve is typically defined by its geometric relationship to two tangents that meet at an intersection point (P.I.), where a simple curve is introduced to connect them. The back tangent refers to the initial tangent...

Horizontal Curve: Problem Solving

Horizontal Curve: Problem Solving

A horizontal curve is characterized by its radius, intersection angle, and stationing of key points. In this case, the radius is 400 meters, and the angle of intersection is 30 degrees, with the station of the point of curvature (P.C.) at 0 + 150 meters. The goal is to determine the station values at the point of intersection (P.I.), point of tangency (P.T.), and midpoint of the curve, as well as the length of the long chord.The process begins with calculating the tangent distance (T) and the...

Horizontal Gene Transfer

Horizontal Gene Transfer

Horizontal gene transfer (HGT) is a process where genetic material moves between organisms within the same generation, unlike vertical gene transfer, which occurs from parent to offspring. HGT plays a crucial role in microbial evolution, adaptation, and survival, particularly in shared environments like the human gut.Mobile genetic elements such as plasmids, prophages, integrons, insertion sequences, and transposons facilitate this process. HGT occurs through three primary mechanisms:...

Shear on the Horizontal Face of a Beam Element

Shear on the Horizontal Face of a Beam Element

To understand shear on the flat side of a prismatic beam element, consider the vertical and horizontal shearing forces, and the normal forces, acting on the element. The element's upper (U) and lower (L) sections, which are divided by the beam's neutral axis, are examined. The equilibrium of these forces is determined by applying the equilibrium equation, which helps identify the horizontal shearing force. This force is directly related to the bending moments and the cross-section's...

Mixtures of Gases: Dalton's Law of Partial Pressures and Mole Fractions

Mixtures of Gases: Dalton's Law of Partial Pressures and Mole Fractions

Unless individual gases chemically react with each other, the individual gases in a mixture of gases do not affect each other’s pressure. Each gas in a mixture exerts the same pressure that it would exert if it were present alone in the container. The pressure exerted by each individual gas in a mixture is called its partial pressure.
