To investigate the prevalence of tonsil hypertrophy in patients with different sagittal skeletal craniofacial patterns, as well as the correlation between tonsil hypertrophy and the type of skeletal pattern. Lateral cephalograms of patients who visited the Department of Orthodontics Division 1, School of Stomatology, Wuhan University during January to August, 2019 were retrospectively collected. Patients (children: age≥6 and ≤12 year; adults: age≥18 year) were divided into three groups according to the ANB (subspinale-nasion-supramental) angle: the skeletal class Ⅰ group (0°≤ANB≤4°), skeletal class Ⅱ group (ANB>4°) and skeletal class Ⅲ group (ANB<0°). Tonsil hypertrophy was diagnosed with lateral cephalogram by two specifically trained orthodontists independently, according to the Baroni's method. The between-group differences in tonsil hypertrophy prevalence were analyzed using chi-square tests with Bonferroni correction (α=0.017). A total of 1 776 patients (593 children and 1 183 adults) were included, among which 672 (37.8%) were with class Ⅰ, 849 (47.8%) with class Ⅱ, and 255 (14.4%) with class Ⅲ skeletal pattern. The prevalence of tonsil hypertrophy in children was 66.3% (393/593). The proportion of children with tonsil hypertrophy in class Ⅲ group [87.0% (60/69)] were significantly higher than that in class Ⅰ [65.6% (145/221), χ²=11.56, 0.017] and class Ⅱ [62.0% (188/303), χ²=15.69, 0.017] groups. The prevalence of tonsil hypertrophy in adults was 23.2% (275/1 183). The proportion of adults with tonsil hypertrophy in class Ⅲ group [42.5% (79/186)] was significantly higher than that in class Ⅰ [19.1% (86/451), χ²=36.50, 0.017] and class Ⅱ [20.2% (110/546), χ²=35.00, 0.017] groups. However, there was no significant difference in the prevalence of tonsil hypertrophy between class Ⅰ and class Ⅱ groups for both children (χ²=0.70, 0.017) and adults (χ²=0.18, 0.017). The prevalence of tonsil hypertrophy in skeletal class Ⅲ patients was significantly higher than that in patients with skeletal class Ⅰ and Ⅱmalocclusion. Tonsil hypertrophy could be an important risk factor for skeletal class Ⅲ patients.
为研究不同矢状骨面型患者扁桃体肥大的患病率，以及扁桃体肥大与骨面型类型之间的相关性。回顾性收集了2019年1月至8月期间就诊于武汉大学口腔医学院正畸一科的患者的头颅侧位片。患者（儿童：年龄≥6岁且≤12岁；成人：年龄≥18岁）根据ANB（鼻下点-鼻根点-颏下点）角分为三组：Ⅰ类骨面型组（0°≤ANB≤4°）、Ⅱ类骨面型组（ANB>4°）和Ⅲ类骨面型组（ANB<0°）。由两名经过专门培训的正畸医生根据巴罗尼法通过头颅侧位片独立诊断扁桃体肥大。采用卡方检验并进行Bonferroni校正（α=0.017）分析扁桃体肥大患病率的组间差异。共纳入1776例患者（593例儿童和1183例成人），其中672例（37.8%）为Ⅰ类骨面型，849例（47.8%）为Ⅱ类骨面型，255例（14.4%）为Ⅲ类骨面型。儿童扁桃体肥大的患病率为66.3%（393/593）。Ⅲ类组儿童扁桃体肥大的比例[87.0%（60/69）]显著高于Ⅰ类组[65.6%（145/221），χ²=11.56，P<0.017]和Ⅱ类组[62.0%（188/303），χ²=15.69，P<0.017]。成人扁桃体肥大的患病率为23.2%（275/1183）。Ⅲ类组成人扁桃体肥大的比例[42.5%（79/186）]显著高于Ⅰ类组[19.1%（86/451），χ²=36.50，P<0.017]和Ⅱ类组[20.2%（110/546），χ²=35.00，P<0.017]。然而，儿童（χ²=0.70，P<0.017）和成人（χ²=0.18，P<0.017）的Ⅰ类组和Ⅱ类组之间扁桃体肥大的患病率无显著差异。Ⅲ类骨面型患者扁桃体肥大的患病率显著高于Ⅰ类和Ⅱ类错牙合患者。扁桃体肥大可能是Ⅲ类骨面型患者的一个重要危险因素。
