Retrospective evaluation of the maxillary sinus septa morphology and it’s incidence in the Şanlıurfa population

Abstract

Background: The purpose of this study is to determine the frequency, number, location and the orientation of the septa in the maxillary sinus by computed tomography. In addition, to evaluate the relationship of sinus septa with age, gender and type of dentition, which are patient related factors.
Materials and Methods: This retrospective study was done by examining the images taken from patients who applied to Harran University Faculty of Dentistry between January 2017 and January 2020. Ethics committee approval was obtained from Harran University Clinical Research Ethics Committee with the decision numbered HRU / 20.09.08. The study was carried out by evaluating the computed tomography images of 500 head and neck regions. While examining the images, the parameters of the patient's age, gender and status of the dentition (full dentition, partial dentition, or edentulous) were recorded. Septas were classified as coronal, sagittal and transversal.
Results: A total of 500 computed tomography images were examined. 446 of them were included in the study because they met the inclusion criteria. Thus, a total of 892 maxillary sinuses were examined. 198 (44.4%) of the patients examined were male and 248 (55.6%) were female. The average age of the patients was 33.4 years old, the youngest was 18 and the oldest was 79 years old. 248 patients (55.6%) were full dentition, 168 (37.7%) were partial dentition and 30 (6.7%) were edentulous. At least one septum was detected in 135 (30.2%) patients. 126 (93.3%) of these patients had only one septum, while 9 (6.7%) had more than one septum. A total of 146 septums were detected in the patients. No significant relation was found between the prevalence of maxillary sinus septa and the age (p = 0.415), gender (p = 0.443) and dentition type (p = 0.078) of the patients. A significant relation was found between the orientation and positions of the maxillary sinus septa (p = 0.017).
Conclusion: As a result of this study, it was observed that approximately one third of the population had a maxillary sinus septa. Planning implant surgeries with three-dimensional images reduces the possible complications. It was also seen that three-dimensional images could change the planning based on two-dimensional images. However, it was evaluated that the results of these study need to be confirmed by more comprehensive studies.

Şanlıurfa Popülasyonunda Maksiller Sinüs Septa Morfoloji ve İnsidansının Retrospektif Olarak Değerlendirilmesi

Öz

Amaç: Bu çalışmanın amacı; maksiller sinüste septa görülme sıklığını, septa sayısını, konumunu ve septanın maksiller sinüste yönelimini bilgisayarlı tomografi ile tespit etmektir. Ayrıca, sinus septasının hasta ile ilgili faktörleri olan yaş, cinsiyet ve dentisyon tipi ile ilişkisini değerlendirmektir.
Materyal ve metod: Bu retrospektif çalışma Harran Üniversitesi Diş Hekimliği Fakültesi hastanesine Ocak 2017-Ocak 2020 tarihleri arasında başvuran hastalardan alınmış görüntüler incelenerek yapıldı. Çalışmada etik kurul onayı Harran Üniversitesi Klinik Araştırmalar Etik Kurulu’dan HRU/20.09.08 sayılı kararı ile alınmıştır. Çalışma 500 adet baş boyun bölgesi bilgisayarlı tomografi görüntüsü değerlendirilerek gerçekleştirildi. Görüntüler incelenirken her hasta için, hastanın yaşı, cinsiyeti, hastanın dişli-kısmi dişli-tam dişsiz oluşu parametreleri kaydedildi. Septalar koronal, sagital ve transversal olmak üzere sınıflandırıldı.
Bulgular: Toplam 500 adet bilgisayarlı tomografi görüntüsü incelendi. Bunların 446 tanesi dahil edilme kriterlerine uyduğundan çalışmaya dahil edildi. Böylece toplam 892 tane maksiller sinüs incelendi. İncelenen hastaların 198'i (%44,4) erkek ve 248’i (%55,6) kadındı. Hastaların ortalama yaşı 33.4, en küçüğü 18, en büyüğü 79 yaşındaydı. Hastaların 248’i (%55,6) tam dişli, 168’i(%37,7) kısmi dişli ve 30’u (%6.7) tam dişsizdi. 135 (%30,2) hastada en az bir septum tespit edildi. Bu hastaların 126 'sında (%93,3) sadece bir septum görülürken, 9’unda (% 6.7) birden fazla septum görüldü. Hastalarda toplam 146 adet septum tespit edildi. Maksiller sinüs septası prevelansı ile hastaların yaşı (p = 0.415), cinsiyeti (p = 0.443) ve dentisyon tipi (p = 0.078) arasında anlamlı bir ilişki bulunamamıştır. Maksiller sinüs septasının yönelim ve konumları arasında anlamlı bir ilişki bulunmuştur (p = 0.017).
Sonuç: Bu çalışma sonucunda popülasyonun yaklaşık üçte birinde maksiler sinüs septası olduğu görüldü. Yapılacak implant cerrahilerinin üç boyutlu görüntülerle planlanması yaşanabilecek komplikasyonların azalmasını sağlamaktadır. Ayrıca üç boyutlu görüntülerin iki boyutlu görüntülere dayalı planlamaları değiştirebileceği görüldü. Ancak bu çalışma sonuçlarının yapılacak daha kapsamlı çalışmalarla doğrulanmasına ihtiyaç olduğu değerlendirildi.
