喉后炎系指病变位于声带后1/3和杓间区而言。近年接诊此类患者增多。本文作者对44例典型酸性喉后炎的病因学、组织学、诊断和治疗加以临床分析。男33例,女11例,平均年龄44岁,中年男性占优势。主要症状为声哑、声疲劳,甚则发声困难,而咽部异物感及顽固性咳嗽使患者十分烦恼,常并有胃肠紊乱,心口灼热感多为其先驱症状。内窥镜检查:喉后部粘膜微红、肿胀,杓间区粘膜增厚,亦可呈肉芽,可能于一侧或双侧声突上有溃疡。44例均在喉病变部位取活组织,病检见:棘细胞层增生致被覆上皮增厚,偶见角 Laryngitis refers to lesions located in the posterior 1/3 of the vocal cords and the intercondylar region. In recent years, the number of such patients has increased. The authors clinically analyzed the etiology, histology, diagnosis, and treatment of 44 cases of typical postlarital laryngitis. There were 33 males and 11 females, with an average age of 44 years old. The middle-aged male predominated. The main symptoms are hoarseness, sonic fatigue, and even difficulty in vocalization. Patients with pharyngeal foreign body sensation and intractable cough make the patient very annoyed. They often have gastrointestinal disorders, and their heartburn sensations are mostly their precursor symptoms. Endoscopy: The mucous membranes in the back of the larynx are reddened, swollen, thickened in the intercondylar mucosa, and may present with granulation. They may have ulcers on one or both of the sonar processes. All the 44 cases were taken from the laryngeal lesions. The pathological examination showed that the epithelium thickened by epithelial cell layer proliferation. Occasionally
