The purpose of this prospective observational study was to evaluate the relationship between nasal morphology and maxillary skeletal pattern. The clinical significance was to emphasize the importance of role of nasal pattern in diagnosis and treatment planning.
The sample included the pre-treatment lateral cephalometric radiographs of 180 South Indian adults (94 women, 86 men), aged 18 to 28 years. Six maxillary and six nasal soft tissue parameters were measured. Pearson correlation coefficients and Analysis of variance were used for statistical analyses.
There were significant correlations between maxillary vertical and sagittal, skeletal and soft tissue parameters. The Mean and standard deviations were correlated between low insignificant range to high significant levels with nasal length, nasal depth and columella convexity. Nasal length also showed significant correlation with inclination of palatal plane. Significant influence of gender was seen on nasal length, nasal depth, columella convexity and nasal tip angle. A statistically significant difference was seen regarding nasal length between males and females, with nasal length being more in males (50.26 ± 4.18) than in females (48.86 ± 3.45), nasal depth being more in males (18.64 ± 2.56) than in females (16.63 ± 2.16), columella convexity being greater in males (4.31 ± 1.26) than in females (3.41 ± 1.13), nasolabial angle decreased in males (87.26° ±13.79°) than in females (89.38° ±15.72°) and nasal tip angle being more in females (80.18° ±9.44°) than in males (73.60° ±10.24°). There was no statistically significant difference in nasal hump between males (-2.01 ± 1.76) and females (-2.02 ± 1.62).
Long nose with increased nasal prominence were seen with increase in the anteroposterior length and vertical height of maxilla. Male and female genders had a varied amount of nasal length, nasal depth and columella convexity along with nasal tip angle.
这项前瞻性观察研究的目的是评估鼻腔形态与上颌骨骨骼模式之间的关系。其临床意义在于强调鼻腔模式在诊断和治疗计划中的重要作用。
样本包括180名年龄在18至28岁之间的南印度成年人（94名女性，86名男性）治疗前的头颅侧位X线片。测量了六个上颌骨和六个鼻腔软组织参数。采用Pearson相关系数和方差分析进行统计分析。
上颌骨垂直和矢状、骨骼和软组织参数之间存在显著相关性。均值和标准差与鼻长、鼻深和鼻小柱凸度在低显著性范围到高显著性水平之间相关。鼻长与腭平面倾斜度也显示出显著相关性。性别对鼻长、鼻深、鼻小柱凸度和鼻尖角度有显著影响。男性和女性在鼻长方面存在统计学上的显著差异，男性鼻长（50.26±4.18）大于女性（48.86±3.45），男性鼻深（18.64±2.56）大于女性（16.63±2.16），男性鼻小柱凸度（4.31±1.26）大于女性（3.41±1.13），男性鼻唇角（87.26°±13.79°）小于女性（89.38°±15.72°），女性鼻尖角度（80.18°±9.44°）大于男性（73.60°±10.24°）。男性（-2.01±1.76）和女性（-2.02±1.62）在鼻驼峰方面无统计学显著差异。
随着上颌骨前后长度和垂直高度的增加，出现了鼻突出增加的长鼻。男性和女性在鼻长、鼻深、鼻小柱凸度以及鼻尖角度方面存在不同程度的差异。
