“…This is higher than that reported by Jones et al [8] (24% for normal and sinus-diseased groups) and Kayalioglu et al in 2000 [11] (22.2% for sinus-disease patients and 12% for non-sinus-diseased patients), but congruent to the findings of Earwaker (1993) [6] (44% on the basis of patients' CT for functional endoscopic sinus surgery evaluation) and Pérez-Piñas et al (2000) [15] (58% amongst patients with sinus disease). Concha bullosa appeared in 25% of patients who revealed paranasal fungus balls.…”

“…Since then, many anatomical abnormalities that impair sinus ventilation or lead to mucosal contact and, thus, might be expected to predispose the development of rhinosinusitis have been studied [2–14]. Among these anatomical variants, deviation of the nasal septum and the presence of a concha bullosa have been the most frequently observed alternatives [15], although the relationship between rhinosinusitis and the many reported anatomical variants still remains controversial.…”

This study aims to determine the relationship between nasal septal deviation, concha bullosa, and chronic rhinosinusitis by using a definitive pathological and simplified model. Fifty-two consecutive sinus computed tomography scans were performed on patients who received endoscopic sinus surgery and whose final diagnosis was paranasal sinus fungus balls. The incidences of nasal septal deviation and concha bullosa for patients diagnosed with paranasal sinus fungus balls among the study group were 42.3% and 25%, respectively. About 63.6% sinuses with fungus balls were located on the ipsilateral side of the nasal septal deviation, and 46.2% were located on the ipsilateral side of the concha bullosa. When examined by Pearson's chi-square test and the chi-squared goodness-of-fit test, no significant statistical difference for the presence of paranasal sinus fungus balls between ipsilateral and contralateral sides of nasal septal deviation and concha bullosa was noted (P = 0.292 and P = 0.593, resp.). In conclusion, we could not demonstrate any statistically significant correlation between the location of infected paranasal sinus, the direction of nasal septal deviation, and the location of concha bullosa, in location-limited rhinosinusitis lesions such as paranasal sinus fungal balls. We conclude that the anatomical variants discussed herein do not predispose patients to rhinosinusitis.

“…Some authors have not included small-sized or lamellar type conchae bullosa in their studies 4. Scribano et al have reported incidences up to 67% and Perez-Pinas et al up to 73% 6,7. Presence of bilateral conchae bullosa ranges from 45%–61.5% 4–8.…”

Objective:To study the benefit of surgery in different types of isolated concha bullosa.Design:Prospective case series.Setting:Academic Medical Center.Patients:Forty seven symptomatic patients complaining of nasal congestion and block, headache and facial pain having concha bullosa without any other sinonasal finding. Their conchae bullosa were classified as lamellar, bulbous and extensive concha bullosa. They were subjected to endoscopic operation.Main outcome measures:Subjective evaluation of postoperative improvement of sinonasal symptoms and objective pre- and postoperative measurement of total nasal resistance by rhinomanometry.Results:Two patients (25%) of lamellar type showed complete improvement, 5 patients (62.5%) showed partial improvement and 1 patient (12.5%) showed no improvement. Regarding bulbous type, 16 patients (72.72%) showed complete improvement, 6 patients (27.28%) showed partial improvement and no patient (0%) showed no improvement. Regarding extensive type, 15 (88.24%) patients showed complete improvement, 2 patients (11.76%) showed partial improvement and no patient (0%) showed no improvement. The total nasal resistance was 0.25 Pa/cm3 per second postoperatively compared with 0.37 Pa/cm3 per second preoperatively in patients having lamellar type; 0.28 Pa/cm3 per second postoperatively compared with 0.71 Pa/cm3 per second preoperatively in patients having bulbous type; and 0.27 Pa/cm3 per second postoperatively compared with 0.67 Pa/cm3 per second preoperatively in patients having extensive type.Conclusions:With proper patient selection, the operative management is of great value in relieving the sinonasal symptoms in patients having isolated Concha bullosa. This will be more obvious in certain types as bulbous and extensive types especially of large sizes.

PurposeThis study aimed to evaluate the prevalence of Haller cells and accessory maxillary ostium (AMO) in cone-beam computed tomography (CBCT) images, and to analyze the relationships among Haller cells, AMO, and maxillary sinusitis.Materials and MethodsVolumetric CBCT scans from 201 patients were retrieved from our institution's Digital Imaging and Communications in Medicine archive folder. Two observers evaluated the presence of Haller cells, AMO, and maxillary sinusitis in the CBCT scans.ResultsAMO was observed in 114 patients, of whom 27 (23.7%) had AMO exclusively on the right side, 26 (22.8%) only on the left side, and 61 (53.5%) bilaterally. Haller cells were identified in 73 (36.3%) patients. In 24 (32.9%) they were present exclusively on the right side, in 17 (23.3%) they were only present on the left side, and in 32 (43.8%) they were located bilaterally. Of the 73 (36.3%) patients with Haller cells, maxillary sinusitis was also present in 50 (68.5%). On using chi-square test, a significant association was observed between AMO and maxillary sinusitis in the presence of Haller cells.ConclusionOur results showed AMO and Haller cells to be associated with maxillary sinusitis. This study provides evidence for the usefulness of CBCT in imaging the bony anatomy of the sinonasal complex with significantly higher precision and a smaller radiation dose.
