Lateral teleroentgenography was used to examine facial skeleton and skull base in 62 patients with progenic occlusion formed because of adenoids. Thirty-four subjects with similar occlusions but without nasopharyngeal diseases were examined for control. Specific features of the cerebral and facial segments of the skull associated with the presence of adenoids were detected, namely, reduced size of the anterior and posterior sections of skull base, increased inclination angle, reduced length of maxillary body base and of apical basis and the distal position of the maxilla, increase of the maxillary body anterior height and of the central segment of the face, excessive growth of mandibular body and particularly of its branch parallelled by its increased angle and anterior height of the face, disordered correlations between various parameters. The authors come to a conclusion that progenic occlusion formation in adenoids results from early synostosis of synchondroses at the skull base and from disharmonious development of the entire facial skeleton.
采用侧位X线摄影术对62例因腺样体肥大形成牙源性咬合紊乱的患者的面部骨骼和颅底进行检查。对34例有类似咬合紊乱但无鼻咽部疾病的受试者进行对照检查。检测到与腺样体存在相关的颅骨脑段和面部段的特定特征，即颅底前后部尺寸减小、倾斜角增大、上颌体基部和根尖基部长度减小以及上颌骨远端位置、上颌体前部高度和面部中央段增加、下颌体尤其是其分支过度生长，同时面部角度和前部高度增加，各参数之间的相关性紊乱。作者得出结论，腺样体肥大导致的牙源性咬合紊乱是由颅底软骨结合的早期骨性融合以及整个面部骨骼的不协调发育引起的。
