If the tube is to remain in place then a tube position check is recommended before each feed and at least once per day. Only smaller diameter (12 Fr or less in adults) nasogastric tubes are appropriate for long-term feeding, so as to avoid irritation and erosion of the nasal mucosa. These tubes often have guidewires to facilitate insertion.
Caldwell-Luc surgery, Caldwell-Luc operation, also known as Caldwell-Luc antrostomy, and Radical antrostomy, is an operation to remove irreversibly damaged mucosa of the maxillary sinus. It is done when maxillary sinusitis is not cured by medication or other non-invasive technique. The approach is mainly from the anterior wall of the maxilla bone.
A feeding tube is a medical device used to provide nutrition to people who cannot obtain nutrition by mouth, are unable to swallow safely, or need nutritional supplementation. The state of being fed by a feeding tube is called gavage, enteral feeding or tube feeding. Placement may be temporary for the treatment of acute conditions or lifelong ...
The canal containing the duct is called the nasolacrimal canal.It is formed by indentations in the inferior nasal conchae, maxilla and lacrimal bone.The canal drains into the nasal cavity through the anterior portion of the inferior meatus, which is between the inferior concha and the floor of the nasal cavity.
[5] [6] At the final phase of aeration, the floor of maxillary sinus is four to five milimetres below the floor of nasal cavity. However, timing of maxillary sinus growth is variable in different people. [5] The maxillary sinus can normally be seen above the level of the premolar and molar teeth in the upper jaw.
The maxilla is a paired bone - the two maxillae unite with each other at the intermaxillary suture. The maxilla consists of: [5] Inferior surface of maxilla. The body of the maxilla: pyramid-shaped; has an orbital, a nasal, an infratemporal, and a facial surface; contains the maxillary sinus. Four processes: the zygomatic process; the frontal ...
The frontal process of the maxilla is a strong plate, which projects upward, medialward, and backward from the maxilla, forming part of the lateral boundary of the nose. Its lateral surface is smooth, continuous with the anterior surface of the body, and gives attachment to the quadratus labii superioris , the orbicularis oculi , and the medial ...
It is situated superoposteriorly upon the lateral nasal wall, opening into the nasal cavity at the posterior portion of the ethmoidal infundibulum. [1] Its opening in the maxillary sinus is present upon the superior part of the medial wall of the sinus [ 2 ] [ 3 ] near the roof of the sinus ; [ 4 ] because of the position, gravity cannot drain ...
