“…In this study, the US angle increased in the short term but decreased in the long term after MSE, which was a slightly different result than what was seen in a previous study [11] that found a significant decrease in the US angle in the short and long term. In the previous studies [3,5,11,25], the authors used the US angle to evaluate NSD. On the other hand, in this study, the MS_C angle significantly increased and the LS angles significantly decreased in the long term, causing the NSD to improve.…”

Background: The aim of this study was to evaluate three-dimensional (3D) changes in nasal septal deviation (NSD) and related nasofacial structures after maxillary skeletal expansion (MSE). Methods: This retrospective study evaluated 28 patients aged 12.0–48.4 years (mean age, 20.4 ± 7.3 years; 12 males, 16 females) diagnosed with transverse maxillary deficiency and treated with MSE. Cone-beam computed tomography (CBCT) images were taken at pre-expansion (T1), post-expansion (T2), and 6-months after MSE (T3) and were reoriented. Three-dimensional coordinates (x,y,z) were constructed using nasion (N) as the reference point (0,0,0). A paired-sample t-test and an independent sample t-test were performed to investigate and compare the 3D changes of the NSD and nasofacial structures after MSE, depending on the direction and amount of NSD and the amount of midpalatal expansion (MPE). Results: NSD was alleviated at T3–T1 in the coronal plane; nasal septal length increased significantly. The absolute nasal floor (NF) angle (2.06° at T1) decreased at T2–T1 (p > 0.05) and increased at T3–T2 (p < 0.05). The midface moved forward and downward, and pogonion (Pog) and menton (Me) moved downward and backward. There were no significant differences between the higher and lower NSD groups and greater and lesser MPE groups. Conclusions: Consequently, NSD was alleviated with variable positive nasofacial changes after MSE in both the short and long term. Therefore, MSE can be used to improve or camouflage facial deformities.

“…Park et al [29] reported that nasal floor canting was highly related to NSD and facial asymmetry, and NSD headed towards the lower nasal floor side. Koo et al [25] suggested that nasal floor canting occurred in the opposite direction to NSD. These findings were consistent with those in our study.…”

“…9 Banyak pasien dengan deviasi septum nasal menunjukkan asimetris pada morfologi os nasal sehingga pemahaman mengenai hubungan deviasi septum dengan morfologi os nasal diperlukan sebelum melakukan tindakan operatif seperti rhinoplasty atau septoplasty. 10 Dari keseluruhan 85 sampel yang memenuhi kriteria inklusi pada penelitian kami, didapatkan jenis kelamin yang paling banyak adalah laki-laki. Temuan ini sesuai dengan penelitian oleh Ozkurt et al yang menyatakan deviasi septum dominan pada laki-laki, dengan prevalensi 65%.…”

Pendahuluan : Deviasi septum nasi merupakan variasi anatomis paling sering, yang ditemukan pada hampir 80% orang dewasa. Septum nasi dapat berpengaruh terhadap pertumbuhan os nasal dan morfologi fasial. Saat ini Computed Tomography (CT) scan disarankan sebagai metode pilihan untuk memberikan gambaran detail tentang morfologi septum dan os nasal. CT scan merupakan teknik non invasif yang dapat digunakan untuk mengukur derajat dan sudut deviasi septum nasi dan luas penampang di bagian rongga hidung. Penelitian ini bertujuan untuk mengetahui korelasi derajat dan arah deviasi septum nasi terhadap morfologi nasal bone menggunakan modalitas CT scan Metode: Desain penelitian cross-sectional dilakukan pada 85 pasien yang memenuhi syarat dan menjalani CT scan kepala. Arah deviasi septum dikategorikan kiri atau kanan, sedangkan derajat dikategorikan ringan (<9o), sedang (9-15°) dan berat (>15°). Morfologi os nasal yang dinilai mencakup ketebalan lateral nasal bone, intermediate nasal bone, sudut internasal, panjang nasal bone, jarak nasal bone ke crista maxillaris, lebar apertura piriformis. Penilaian morfologi os nasal dicatat dalam bentuk nilai median. Korelasi antara derajat dan arah deviasi septum nasi terhadap morfologi nasal bone dilakukan dengan pengujian korelasi Spearman. Hasil : Paling banyak pasien menunjukan deviasi septum ke kiri, sebanyak 47 sampel (55,3%) sedangkan pasien dengan deviasi septum ke kanan sebanyak 38 sampel (44,7%). Paling banyak pasien menunjukkan derajat deviasi sedang, sebanyak 44 sampel. Terdapat korelasi yang signifikan antara ketebalan os nasal lateral kanan dan kiri, dan ketebalan os nasal intermediat kanan dan kiri dengan arah deviasi septum nasi (P<0,001). Terdapat pula korelasi yang signifikan antara jarak os nasal dengan crista maxilaris dan lebar apertura piriformis dengan derajat deviasi septum nasi (p = 0,037; p = 0,005) Kesimpulan : Penelitian ini menunjukkan bahwa arah dan derajat deviasi septum nasi dapat mempengaruhi morfologi os nasal. Os nasal lebih tebal pada sisi yang deviasi dibandingkan sisi kontralateralnya. Temuan ini dapat menjadi pertimbangan untuk klinisi terutama sebelum melakukan tindakan operatif untuk pasien dengan deviasi septum nasi.
