The tube is then marked at this level to ensure that the tube has been inserted far enough into the patient's stomach. Many commercially available stomach and duodenal tubes have several standard depth markings, for example 46 cm (18 in), 56 cm (22 in), 66 cm (26 in) and 76 cm (30 in) from distal end; infant feeding tubes often come with 1 cm ...
The advantage of this technique is that the entire posterior pharyngeal wall can be visualized. Disadvantages include the following: 1. This procedure requires radiation, which is a particular concern for children. 2. It is not well tolerated by some children because it requires injection of barium into the nasopharynx through a nasal catheter. 3.
Intravenous injection of Buscopan (Hyoscine butylbromide) 20 mg or glucagon 0.3 mg is used to distend the stomach and slow down the emptying of the contrast into the duodenum. [13] Right anterior oblique (RAO) view is used to demonstrate antrum and greater curve of stomach. Supine position is to demonstrate antrum and body of stomach.
Augmentation pharyngoplasty is a kind of plastic surgery for the pharynx (soft tissue at the back of the mouth) when the tissue at the back of the mouth is not able to close properly. It is typically used to correct speech problems in children with cleft palate .
The pharynx (pl.: pharynges) is the part of the throat behind the mouth and nasal cavity, and above the esophagus and trachea (the tubes going down to the stomach and the lungs respectively). It is found in vertebrates and invertebrates, though its structure varies across species. The pharynx carries food to the esophagus and air to the larynx.
During a pharyngoplasty, incisions are made into the lateral and posterior pharyngeal walls in an effort to elevate strips of native tissue away from its normal position. These elevated tissues are called flaps and remain pedicled to their native pharyngeal structures as a means of maintaining their blood flow.
The danger space serves as an important pathway for complicated infections of the posterior pharynx to enter the chest and spinal column. Anterior to the parapharyngeal space is the masticator space which contains the lower dental row, muscles of mastication, the inferior alveolar nerve as well as branches of cranial nerve V.
Pulmonary aspiration is the entry of solid or liquid material such as pharyngeal secretions, food, drink, or stomach contents from the oropharynx or gastrointestinal tract, into the trachea and lungs. [1] When pulmonary aspiration occurs during eating and drinking, the aspirated material is often colloquially referred to as "going down the ...
