To determine the effect of tongue position on facial morphology of Pakistani adults and different growth patterns.
Cross-sectional study. Place and Duration of the Study: Department of Orthodontics, Karachi Medical and Dental College, Karachi, Pakistan, from January to April 2021.
The study included individuals aged 17 to 30 years with no history of prior orthodontic treatment, absence of wound, burn, or scar tissue in the neck region, comfortable breathing through the nose, absence of deglutition disorder, and a skeletal Class I or II relationship. The exclusion criteria were a cleft lip or palate, or a history of chronic mouth breathing, snoring, or tonsillectomy. According to their skeletal relationships, the subjects were split into three groups; Group I (low-angle), Group II (normal growth), and Group III (high-angle). Vertical growth pattern was assessed on radiograph by interpreting the values of NS / ML (nasion-sella / mandibular plane) angle, and angle formed between FH / ML (Frankfort horizontal plane / mandibular plane). A predesigned proforma was used to record all the measurements made on pre-treatment lateral cephalograms by the sole investigator. Data were analysed using SPSS 24.0.
Data from the lateral cephalogram of 79 patients, consisting of 18 (22.8%) males and 61 (77.2%) females who met the inclusion criteria, were analysed. The sample included 15 low-angle, 45 normal vertical growth, and 19 high-angle cases. Fifty participants had Class I skeletal relationships, while 29 had Class II relationships. According to the ANOVA test, FH / ML and NS / ML measurements showed no statistically significant variations in tongue position and growth trends.
There was no statistically significant difference between tongue position and facial morphology of Class I or II subjects with different vertical growth patterns. However, there was a statistically sufficient evidence showing the tongue height was greater in Class I skeletal relationship patients as compared to Class II skeletal cases (p = 0.008).

确定舌位对巴基斯坦成年人不同生长模式的面型的影响。
横断面研究。
卡拉奇医科大学牙科系正畸科，巴基斯坦卡拉奇，2021 年 1 月至 4 月。
该研究纳入了年龄在 17 至 30 岁之间、无正畸治疗史、颈部无伤口、烧伤或疤痕组织、通过鼻子舒适呼吸、无吞咽障碍、且骨骼关系为 I 类或 II 类的个体。排除标准为唇腭裂或有慢性口呼吸、打鼾或扁桃体切除术病史。根据骨骼关系，将受试者分为三组：I 组（低角）、II 组（正常生长）和 III 组（高角）。通过解读 NS / ML（前囟-蝶鞍/下颌平面）角和 FH / ML（法兰克福水平面/下颌平面）之间形成的角度，在放射影像上评估垂直生长模式。使用预先设计的表格记录唯一研究者在治疗前侧位头颅侧位片上进行的所有测量。使用 SPSS 24.0 分析数据。
对符合纳入标准的 79 例患者（18 例男性，61 例女性）的侧位头颅侧位片进行了数据分析。该样本包括 15 例低角、45 例正常垂直生长和 19 例高角病例。50 名参与者具有 I 类骨骼关系，29 名参与者具有 II 类骨骼关系。根据 ANOVA 检验，舌位和生长趋势的 FH / ML 和 NS / ML 测量值没有统计学上的显著差异。
在具有不同垂直生长模式的 I 类或 II 类患者中，舌位与面型之间没有统计学上的显著差异。然而，有足够的统计证据表明，在 I 类骨骼关系患者中，舌高大于 II 类骨骼病例（p = 0.008）。
