pharyngeal abscess incision and drainage

In the pharyngeal space infection, there is abscess formation. Treatment of diseases: parapharyngeal abscess after swallowing abscess Indication In the pharyngeal space infection, there is abscess formation. Preoperative preparation Read the x-ray lateral radiograph to understand the cervical spine and the extent of the abscess, and prepare the oxygen and tracheostomy device for application when necessary. Surgical procedure 1. After oral incision, take the supine position. After the neck side incision, take the supine position, and put a small sandbag under the shoulder. 2. If the abscess is more obvious in the oropharyngeal wall of the oral cavity, take the oral route, open the mouth with a mouth opener, puncture the pus with a puncture needle at the most prominent part of the abscess, and then make a longitudinal incision to cut the mucosa and submucosal tissue. Use a hemostat to open, separate the muscle tissue into the abscess, allow the pus to overflow, and use the aspirator to drain the pus. 3. If the position of the abscess and the neck side are obviously swollen, take the neck side incision. At the lower edge of the affected mandibular angle, along the anterior border of the sternocleidomastoid muscle, the curve is down to the level of the hyoid bone, making all the mouth. Cut the skin, subcutaneous tissue, fascia and platysma, separate the loose connective tissue in the posterior submandibular region, expose the submandibular gland, and separate the vascular clamp along the lower edge of the submandibular gland to the mandibular angle, and then along the styloid mandibular ligament to the styloid process Where, and separated from the outside of the styloid process to the base of the skull, the anterior part of the pharyngeal abscess can be reached. Then, the anterior border of the sternocleidomastoid muscle is separated backward, and the internal and external carotid arteries and the internal jugular vein are exposed. The anterior fascia of the thyroid gland, trachea, esophagus and cervical vertebrae can be seen with the vascular clamp applied along the anterior fascia of the cervical spine. The posterior part of the pharyngeal space can be drained, and after the pus is drained as much as possible, the rubber drainage strip is placed, and the incision does not need to be sutured.
