The ethmoidal funnel (ethmoidal drainage) is a complex anastomosis between the nasal cavity and the ethmoid sinus, which in configuration repeats the internal nasal passage. The ethmoidal drain is located at the end of the nasal septum at the lower end of the external nasal meatus.
Functions of a ethmoid stoma in the body: * ensuring adequate drainage of purulent discharge; * if the facial bone is damaged, sinusitis is accompanied by the formation of a rough abrasion with exposure of spongy tissue. This is accompanied by an intense inflammatory process inside the skull. Moreover, destructive changes can continue for several years. During this pathology, a connection between the nasal cavity and the cranial cavity occurs and a drainage device must be installed in the ethmoid bone. Usually, a rubber (plastic) pipe, cut transversely, is used to remove purulent exudate;
The space of the ethmoidal sinus is separated from the cave of the ethmoidal concha 6-8 by a perforated plate. The olfactory openings on the body of the ethmoid bone open on the lateral walls of the caves in the bone plate connecting the main surface of the bodies with the wide part of the sphenoid bone. Each shell is divided from the upper platform of the nose down by 8-12, less often 5-6 holes. From these begin 4-5 thin branches, bone or fibrous, which in the form of a mesh penetrate the thickness of the wall of the sinuses. They are called venous openings (emissary openings). Coming out of the paranasal sinus, the oral cavity branches and passes almost through the opening into the maxillary sinus.
Introduction: The ethmoidal infundibulum is a unique anatomical structure in the human skull that plays an important role in the mechanism of breathing, smell and hearing. Studying the anatomy of the ethmoidal infundibulum can help in understanding the mechanisms of functioning of the human body and the clinical diagnosis of various diseases. In this article we will look at the structure, functions and main diseases of the ethmoid funnel.
Structure of the Lattice Funnel:
The ethmoid bones are paired structures located in the middle region of the skull above the eyes and jaw. They form the ethmoid sinus, which has the shape of a funnel with many holes. The ethmoid bones are connected to the other bones of the skull through numerous sutures.
The main parts of the Grid Funnel include
