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 .
Vocal cord injection is ineffective for closing a large glottal gap. [6] Arytenoid adduction is more effective than medialization thyroplasty for closing a posterior gap. It has been suggested that this is because arytenoid adduction directly rotates the arytenoid cartilage and thus more actively medializes the posterior aspect of the vocal ...
Additionally, aberrant pharyngeal vascular anatomy can serve as a contraindication to the pharyngeal flap surgical procedure. Internal carotid arteries within the pharyngeal walls can take an atypical medial course through the posterior aspect of the pharyngeal wall, particularly in patients with velocardiofacial syndrome.
Research has found that pharyngeal flap surgery has been most effective for those with a sagittal closure pattern (good lateral wall movement but poor velar movement (Armour et al., 2005)). Pharyngeal flap surgery is not recommended for everyone and alternative treatment methods are available. One alternative is the use of a prosthesis. In some ...
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.
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.
[citation needed] It is formed as a thickening of the pharyngeal mucosa superior to the superior pharyngeal constrictor muscle. It attaches to the basilar part of occipital bone, the petrous part of the temporal bone (medial to the pharyngotympanic tube), the (posterior border of the) medial pterygoid plate, and the pterygomandibular raphe. It ...
Posterior pharyngeal flap surgery is mostly used for vertical clefts of the soft palate. The surgeon cuts through the upper layers of the back of the throat, creating a small square of tissue. This flap remains attached on one side (usually at the top). The other side is attached to (parts of) the soft palate.
