Abstract
이 연구의 목적은 computerized tomography (CT)를 이용하여 adenoid hypertrophy patients and tonsillar hypertrophic patients 으로 분류되어 있는 어린이들의 두개안면의 비율을 평가하는 것이다. 이 후향연구의 총 63 명 환자는 대상으로 다음과 같은 그룹으로 나누어져 있다: control group (C group)에 17 명 (10 명 남성과 7 명 여성; 평균 나이, 5.18 ± 1.51 세), adenoid hypertrophy group (A group)에 15 명 (10 명 남성과 5 명 여성; 평균 나이, 5.13 ± 1.41 세), tonsillar hypertrophy group (T group)에 15 명 (9 명 남성과 6 명 여성; 평균 나이, 5.27 ± 1.44 세) 그리고 adenotonsillar hypertrophy group (AT group)에 16 명 (8 명 남성과 8 명 여성; 평균 나이, 5.00 ± 1.41 세). 4 그룹의 사이의 다음 측정치의 차이를 one-way ANOVA 와 post-hoc Scheffe test 으로 통하여 비교하였다: inter-gonion width, inter-J width, nasal cavity width, maxillary inter-canine width, maxillary inter-molar width, palatal depth, maxillary arch length, and nasion-crest of the alveolar bone between the central incisors (N-Cr). Inter-Gonion width 가 T 와 AT group 에서 C group 보다 통계적으로 유의성이 있는 차이로 작았다 (p < 0.05). Inter-J width 가 AT group 에서 T group 보다 통계적으로 유의성이 있는 차이로 작았다 (p < 0.05). Maxillary inter-molar width 가 A 와 AT group 에서 T group 보다 통계적으로 유의성이 있는 차이로 작았다 (p < 0.05). 결과를 통하여 tonsillar hypertrophy 가 3-7 세 나이의 어린이들의 inter-gonion width 를 유의성이 있게 제한할 수 있음을 확인할 수 있었다. adenoid hypertrophy 가 3-7 세 나이의 어린이들의 maxillary width 와 maxillary inter-molar width 를 유의성이 있게 제한할 수 있음을 확인할 수 있었다.

The aim of this study was to evaluate craniofacial proportions in children classified into adenoid and tonsillar hypertrophic patients, by using a systematic reproduceable method for the assessment, utilizing computerized tomography (CT) scans. This retrospective study included a total of 63 subjects (age range, 3-7 years) who were distributed as the following: control group (C group) had 17 subjects (10 males and 7 females; mean age, 5.18 ± 1.51 years), adenoid hypertrophy group (A group) had 15 subjects (10 males and 5 females; mean age, 5.13 ± 1.41 years), tonsillar hypertrophy group (T group) had 15 subjects ( 9 males and 6 females; mean age, 5.27 ± 1.44 years), and adenotonsillar hypertrophy group (AT group) had 16 subjects (8 males and 8 females; mean age, 5.00 ± 1.41 years). The differences in the following measurements between the four groups were compared using one-way ANOVA test and post-hoc Scheffe test: inter-gonion width, inter-J width, nasal cavity width, maxillary inter-canine width, maxillary inter-molar width, palatal depth, maxillary arch length, and nasion-crest of the alveolar bone between the central incisors height (N-Cr). The inter-Gonion width was smaller in T and AT groups compared to the C group (p < 0.05). The inter-J width was significantly smaller in AT group compared to T group (p < 0.05). The maxillary inter-molar width was significantly smaller in A and AT groups compared to T group (p < 0.05). The results indicate that the tonsillar hypertrophy led to a reduction of the inter-gonion width in young children aged between 3 to 7 years old. The adenoid hypertrophy led to a reduction of the inter-J width and the maxillary inter-molar width in young children aged between 3 to 7 years old. Both the tonsillar and adenoid hypertrophy did not have any other significant effect within the scope of the current study.
