Abstract

Amaç: Bu çalışmanın amacı iskeletsel Sınıf II
malokluzyona sahip bireylerde (ANB>5)
nazofarengeal ve orofarengeal havayolu boyutunun pre-pubertal, pubertal ve
post-pubertal gelişim dönemlerinde karşılaştırılarak değerlendirilmesidir.

Gereç ve Yöntem: Anabilimdalı
arşivinden iskeletsel Sınıf II malokluzyona sahip 45 vakanın (21 erkek, 24
kız)(18 pre-pubertal, 12 pubertal, 15 post-pubertal) tedavi başı lateral
sefalometrik filmleri seçilmiştir. Çalışmada 13 sefalometrik nokta, 4 açısal
ölçüm, 4 doğrusal ölçüm ve 4 oransal ölçüm Pordios bilgisayar programı
kullanılarak analiz edilmiştir. Parametrelere ait ortalama ve standart sapmalar
hesaplanmıştır. Üç grup arasındaki farkın hesaplanması için istatistik analiz
(ANOVA ve Duncan’s testi) uygulanmıştır.

Bulgular:Pre-pubertal grup en küçük
nazofarengeal hava yolu ölçümüne (NAS) (21,3mm ±5,1) sahip bulunmuştur, ve NAS
ölçümü erişkin gruba doğru artış göstermiştir (23,2mm±4,8 to  26,6mm±4,4).
Diğer yandan, orofarengeal hava yolu ölçümü (OAS), gruplar arasında anlamlı bir
fark göstermemektedir (10,1mm±2,7- 8,1mm±2,3 8,8mm±2,2)

Sonuç:

Bu çalışma, iskeletsel Sınıf
II bireylerde üst havayolu alanının gelişim ile arttığını, orofarengeal
boşluğun sabit kaldığını göstermektedir

EVALUATION OF NASOPHARYNGEAL AIRWAY SPACE OF SKELETAL CLASS II SUBJECTS IN
DIFFERENT GROWTH STAGES

 Aim:The aim of this study was to compare the dimensions of the nasopharynx and oropharnynx of individuals with skeletal Class II anomaly (ANB>5 degrees) during the pre-pubertal, pubertal and post-pubertal (adult)growth periods.

Material and Method: A total of 45 pre-treatment lateral cephalograms of skeletal Class II cases
(21 boys, 24 girls)(18 in pre-pubertal, 12 in pubertal, 15
in post-pubertal growth periods) were selected from the department archives. 13 cephalometric
landmarks, 4 angular measurements, 4 linear measurements and 4 rational
measurements were analyzed using Pordios computer program. Means and standard deviations of the parameters have been
calculated and statistical analysis (Analysis of Variance and Duncan’s
tests) was utilized to compare the differences
between the three groups.

Results:Pre-peak group showed the smallest nasopharyngeal airway space (NAS) (21,3mm ±5,1), and NAS showed an increase towards the adult group (23,2mm±4,8 to  26,6mm±4,4). On the other hand, oropharyngeal airway space (OAS), which was measured at the level of the tip of the soft palate,  did not show a significant difference between the groups (10,1mm±2,7- 8,1mm±2,3 8,8mm±2,2).

Conclusion: This study demonstrated that the
oropharyngeal gap remained constant in skeletal Class II individuals, while
superior airway space increased with growt
