The amount of maxillary and mandibular growth and the direction of maxillary growth were studied in 38 children during the 5 years after adenoidectomy for correction of severe nasopharyngeal obstruction. The amount of mandibular growth measured between successive gnathion points on superimposed radiographs was significantly greater in the group who had an adenoidectomy than in the matched controls. In the boys the difference was 3.8 mm (p less than 0.001), and in the girls the difference was 2.5 mm (p less than 0.01). The boys also showed a tendency toward greater growth in the maxilla as measured between successive subnasal points (1.2 mm, p less than 0.05). We detected no difference in the direction of maxillary growth between who had undergone adenoidectomy and the controls.
对38名因矫正严重鼻咽阻塞而接受腺样体切除术的儿童，在术后5年研究了上颌骨和下颌骨的生长量以及上颌骨的生长方向。在叠加的X线片上，连续测量颏下点之间下颌骨的生长量，结果显示接受腺样体切除术的组比配对对照组明显更大。男孩的差异为3.8毫米（p<0.001），女孩的差异为2.5毫米（p<0.01）。连续测量鼻下点之间的距离，男孩上颌骨的生长也有更大的趋势（1.2毫米，p<0.05）。我们未发现接受腺样体切除术组与对照组在上颌骨生长方向上存在差异。
