Result
All 11 patients underwent surgery and perioperative education without
any local or systemic complications. During the follow-up, there were 4
cases of residual pseudomembrane observed under the electronic
laryngoscope, of which 2 cases appeared in 1 month postoperatively, and
2 cases in 3 months after surgery. After 8 weeks of oral PPI treatment,
3 cases of mucosa recovered smooth when follow-up again, 1 case became
smooth mucosa when the third follow-up. There were no relapse in the
next follow-up. The remaining 7 cases of granuloma disappeared under the
electronic laryngoscopy. After an average of 6.2 months, all patients
preexisting symptoms such as hoarseness, foreign body sensation in the
throat, and coughing, and laryngoscopic signs were eventually clinically
cured (Figure 2).
