Usually, patients heal after 2 weeks of pharyngeal cyst surgery. The pharynx is divided into three parts, namely the nasopharynx, oropharynx and laryngopharynx, and pharyngeal cysts are cysts that occur in all three of these parts. These cysts can be removed with low-temperature plasma under direct endoscopic view, with little intraoperative bleeding, easy removal of the cysts, and mild postoperative reactions. However, patients have a relatively long recovery time, usually about 2 weeks. In addition, patients should pay attention to diet after cyst surgery in oropharynx and laryngopharynx, they need to eat semi-liquid diet, avoid eating overheated, spicy and stimulating food also can not eat, one week later can be transitioned to normal diet, but to swallow in small mouth to avoid bleeding caused by premature detachment of pseudomembrane after surgery. In addition, patients should also pay attention to oral hygiene after surgery, rinse their mouth in time after meals, and can use warm boiled water or compound chlorhexidine mouthwash to rinse their mouth. At the same time, avoid talking loudly and coughing hard to prevent bleeding caused by coughing up the mucosa of the pharynx.
