“…The third most common anatomical variant is concha bullosa which was found in 87 study population with prevalence of 43.5% of cases. In our study there is no statistical relation of concha bullosa with sinusitis which has insignificant p value of 0.6.This is in correlation with another recent study done in Mar 2018 by Raja Kalaiarasi et al 35 The study was done to investigate the variations of the concha bullosa, based on paranasal sinus imaging, and its possible association with sinusitis. The study concluded that there was no statistically significant association between any types of middle turbinate concha with sinusitis.…”

To investigate the prevalence of anatomic variants of the sinonasal cavities using 128-slice-Multidetector CT and to determine their relation to sinonasal mucosal disease. Material and methods: A total of 200 patients were included. The inclusion criteria were patients with clinical symptoms of chronic rhinosinusitis and e exclusion criteria were patients with history of trauma, sinus surgery and sinonasal tumours and patients with contraindications for CT like pregnancy. All the patients with symptoms of chronic rhinosinusitis underwent CT on a 128-MDCT with field of view of 16cm from roof of frontal sinus till floor of maxillary sinus with reconstruction of 0.625mm. The study was acquired in axial plane and coronal, sagittal reconstructions were made.The CT scans was evaluated for the presence of anatomic variants of the sinonasal cavities and associated sinusitis. Results: The paranasal sinus anatomical variants are highly variable as proved by various previous studies. In our study the most common anatomical variant was deviated nasal septum, followed by agger nasi and concha bullosa. There was no statistically significant correlation between any of these anatomical variants and chronic rhinosinusitis in our study. Conclusion: The paranasal sinus anatomical variants are highly variable. In our study, the most commonest anatomical variant was deviated nasal septum, followed by agger nasi and concha bullosa. There was no statistically significant correlation between any of these anatomical variants and chronic rhinosinusitis in our study.

“…The present study has adopted the definition by Zinreich et al, 37 who have considered any pneumatization degree as CB and was found in 61.4% of the scans (Figure 1 b). Other studies have found a prevalence of 30.6% by Alsowey et al, 32 31.7% by Kalaiarasi et al, 36 30% and 51% by two different studied in Turkey. 6,29 The middle turbinate usually curves medially toward the nasal septum.…”

“…Concha bullosa (CB) is one of the most frequently found anatomic variants. The incidence of CB in the population ranges from 13 to 73% in literature; 36 the differences reported may have been influenced by the aeration degree, and lower rates suggest that only large turbinates may have been taken into consideration. The present study has adopted the definition by Zinreich et al, 37 who have considered any pneumatization degree as CB and was found in 61.4% of the scans (Figure 1 b).…”

Background and objective: Variation in paranasal sinus anatomy, as shown on computed tomographic scans, is of potential significance as it may pose risks during surgery or predispose to certain pathologic conditions. This study aimed to investigate the frequency of anatomic variants of the nasal cavity and paranasal sinuses in our population and determine their relationship with gender and find out the association of these variants with mucosal abnormalities. Methods: This was a cross-sectional study conducted at the College of Medicine, Hawler Medical University from October 2017 to January 2019. A review of computed tomography scans of the paranasal sinuses of 300 patients was done; special attention was directed toward identifying bony anatomic variants and mucosal abnormalities. Results: Frequent variants were: Agger nasi cells (72%), nasal septal deviation (71.7%), Haller cells (70.7%), concha bullosa (61%), elongation of uncinate process (69.7%) and different variants of the sphenoidal sinus (78.8%). The frequency of variants did not differ significantly with respect to gender, except for sphenoidal variants along with Keros types and asymmetry of the ethmoidal roof. A significant association was found between middle concha variants and inferior turbinate enlargement (P <0.001). Conclusion: Anatomic variants of the paranasal sinus region were common in our population; the most frequent ones were those involving the nasal septum, ethmoid air cells, sphenoid sinuses, and middle turbinates. The study of these variants is important for the management of paranasal sinus region disease.

“…The incidence of pneumatization of the MT is between 13 and 53.6% (8). CB is usually asymptomatic and diagnosed incidentally by CT. From time to time, an over-pneumatized MT can lead to deviated nasal septum, contact headache, nasal obstruction, and sinusitis (9).…”

Amaç: Konka büllozanın (KB) kafa tabanı yüksekliği üzerindeki etkisini göstermektir. Yöntemler: Hastanemizde sinüzit nedeniyle paranazal sinüs tomografisi çekilen 1022 hastanın dosyaları retrospektif olarak tarandı. Üç yüz otuz hastada bilateral, 330 hastada unilateral KB vardı, ancak 330 hastada KB yoktu. Kesitleri ve pozisyonları uygun olmayan hastalar çalışma dışı bırakıldı. Çalışmaya 18-72 yaş arası toplam 990 hasta dahil edildi. Hastaların beşyüz altmış yedisi kadın, 423'ü erkekti. Her grupta erkek ve kadın hastaların sağ ve sol kafatası tabanının yükseklikleri kendi içlerinde ve birbirleri arasında karşılaştırıldı. Kafatası tabanının yüksekliği, kribriform plaka ile fovea etmoidalis arasındaki lateral lamel boyunca koronal düzlemde ölçülmüş ve bu ölçümler Keros sınıflandırması kullanılarak sınıflandırılmıştır. (Keros tip 1: 1-3 mm, Keros tip 2: 4-7 mm, Keros tip 3: 8-16 mm). Bulgular: Bilateral KB grubunda kadın ve erkek hastaların sağ ve sol kafatası tabanı yükseklikleri arasında istatistiksel olarak anlamlı bir fark saptanmadı. Ayrıca, kadın ve erkeklerin kendi içlerinde yapılan karşılaştırmalarında da istatistiksel anlamlı bir fark saptanmadı. Unilateral KB grubunda kadın ve erkek hastaların KB'si olan ve KB'si olmayan taraf kafatası tabanı yükseklikleri arasında istatistiksel olarak anlamlı bir fark saptanmasına rağmen, kadın ve erkeklerin kendi içlerinde yapılan karşılaştırmalarında istatistiksel anlamlı bir fark saptanmadı. Sonuç: Unilateral KB'li hastalarda, KB olan ve olmayan taraflar arasında kafatası tabanı asimetrisi vardır ve komplikasyonları önlemek için bu dikkate alınmalıdır. Anahtar Kelimeler: Konka bülloza, kafatası tabanı, paranazal sinüs tomografisi Introduction: To demonstrate the effect of concha bullosa (CB) on the height of the skull base. Methods: We retrospectively scanned the files of 1022 patients who had undergone paranasal sinus tomography for sinusitis in our hospital. Three hundred thirty patients had bilateral, and 330 had unilateral CB, but 330 patients did not have CB. Patients with inappropriate sections and positions were excluded from the study. A total of 990 patients aged between 18 and 72 years were included in the study. Five hundred sixtyseven of the patients were female, and 423 were male. In each group, the heights of the right and left skull base of male and female patients were compared within themselves and between each other. The height of the skull base was measured in the coronal plane along the lateral lamella between the cribriform plate and the fovea ethmoidalis, and these measurements were classified as Keros classification. (Keros type 1: 1-3 mm, Keros type 2: 4-7 mm, Keros type 3: 8-16 mm). Results: There was no statistically significant difference in the comparison between right and left skull base heights of female and male patients in bilateral CB group. Also, there was no statistically significant difference between the comparison of women and men within themselves. There was a statistically significant difference between CB side and non-CB side sk...
