Introduction
Perform local anesthesia on the mucosal surface near the puncture site. Use a large-bore needle attached to a syringe and insert it at the most prominent part of the abscess. After insertion, aspirate to check for pus in the syringe; once pus is confirmed, proceed with incision and drainage of the peritonsillar abscess. Take care to avoid an angle that is too lateral or excessive depth during puncture to prevent injury to major blood vessels in the parapharyngeal space.
A tonsillar cyst can cause significant throat discomfort, a sensation of a foreign body, and when complicated by infection, symptoms such as pain, difficulty swallowing, and fever may occur. Prompt treatment with tonsil aspiration and abscess drainage is required. The procedure is as follows:
1. Before performing the tonsillar aspiration, apply a local anesthetic such as lidocaine to the mucosal surface around the puncture site.
2. Once the anesthetic has taken full effect, attach a large-bore needle to a syringe and insert it into the most prominent part of the abscess.
3. After insertion, gently aspirate; if pus is drawn into the syringe, this confirms the diagnosis of peritonsillar abscess.
4. Incise and drain the peritonsillar abscess. Once the pus is completely evacuated, the patient's pain and difficulty swallowing should significantly improve.
Note: Be careful not to angle the needle too laterally or insert it too deeply to avoid injury to major blood vessels in the parapharyngeal space.
