Abstract:Abstract Objective:To analyze clinical cases of lingual tonsillar hypertrophy in patients after palatine tonsillectomy. Methods:Clinical data of 10 patients diagnosed with lingual tonsil hypertrophy following palatine tonsillectomy admitted to the Department of Otorhinolaryngology Head and Neck Surgery, the Sixth Medical Center of Chinese PLA General Hospital from May 2012 to May 2025 were retrospectively analyzed. Results:Among the 10 patients, there were 7 males and 3 females. All patients had a prior history of palatine tonsillectomy, including 4 cases of simple bilateral palatine tonsillectomy, 2 cases of uvulopalatopharyngoplasty combined with bilateral palatine tonsillectomy, 3 cases of bilateral palatine tonsillectomy plus adenoidectomy, and 1 case of unilateral palatine tonsillectomy. Two patients presented without obvious pharyngeal discomfort preoperatively; the rest complained of foreign body sensation in the pharynx, among whom 2 had muffled speech with globus sensation, 2 suffered from snoring accompanied by apnea, and 1 presented with choking cough. All patients underwent lingual tonsillectomy under general anesthesia. Postoperative recovery was uneventful except for one case of hemorrhage on the 5th postoperative day. The follow-up period ranged from 1 to 14 years,and remarkable relief of symptoms was observed in all patients. Conclusion:Lingual tonsil hypertrophy may occur after bilateral tonsillectomy, which deserves sufficient clinical attention.
