2026
Medial canthopexy allows correction of the position and fixation of the medial canthal tendon. Due to the technical difficulties of this procedure, there is a need for a detailed protocol for educational purposes. Here, we describe a standardized reproducible technique for bilateral medial transnasal canthopexy by an orbitonasal approach.

Frustration and Conflict: Approach-Approach, Approach-Avoidance

2025
Frustration occurs when people are obstructed or prevented from achieving a desired goal or fulfilling a perceived need. For example, when someone's input is ignored in a discussion, it can lead to feelings of frustration. Conflict, however, arises from opposing interests, goals, or actions. Conflicts can take various forms based on the nature of these opposing desires or goals. One common type of conflict is the Approach–Approach Conflict. In this case, a person faces two desirable options,...

Since the Roman Empire, physicians have described the connection between alterations in function of specific parts of the body and specific disease states and have sought to further scientific understanding to improve bedside diagnosis. However, in this modern age of increasing technology within medical diagnostics, it...
FAQs
Endoscopic visualization is central to the approach because it lets surgeons see the nasal cavity and adjacent spaces while advancing slender instruments. The camera supports navigation through confined anatomy, while specialized instruments allow operative work along the same route. This combination helps surgeons preserve surrounding tissue during access.
Careful management of nasal anatomy matters because the route passes through the nasal cavity before reaching deeper targets. Surgeons must rely on direct endoscopic visualization to understand the spaces and avoid unnecessary disruption of nearby tissue. This anatomical control is especially relevant when the intended site lies near the skull base or pituitary area.
Compared with approaches requiring a large external incision, this route can limit visible scarring and reduce disruption of facial tissues. Its value is therefore not only cosmetic; preserving facial structures may also support a less disruptive surgical pathway. The overview identifies this minimally invasive character as an important development in modern surgery.
The approach is relevant across several anatomical targets rather than a single diagnosis. In medicine, it supports procedures involving the sinonasal region, skull base, and pituitary area. This range reflects its ability to provide a route to structures behind the nose, including sites important in complex head and brain conditions.
A typical operative workflow centers on endoscopic navigation: the surgeon enters through the nasal passages, uses the camera to inspect the nasal cavity, and advances specialized instruments toward the intended adjacent space. Throughout the procedure, managing nasal anatomy and maintaining visualization are essential for controlled access and tissue preservation.
Development of this route has expanded minimally invasive surgery and supported new ways to address complex head and brain conditions. Its continued importance comes from combining endoscopic navigation with anatomy-focused technique, allowing surgeons to reach relevant structures while limiting visible scarring and disruption of facial tissues. This progress illustrates how surgical innovation can arise from refining access routes.
