Paranasal Sinus Computed Tomography

Nearly all patients with cystic fibrosis (CF) have abnormal findings on plain paranasal sinus radiographs. To establish this relationship more accurately, 58 CF patients with nasal symptoms were evaluated with paranasal sinus computed tomography (CT). Bilateral medial displacement of the lateral nasal wall in the middle meatus and uncinate process demineralization were seen in 43 patients (74%). Three patients (5%) had unilateral displacement and uncinate demineralization. Ten patients had maxillary sinus opacification, two patients (3.5%) had unremarkable paranasal sinuses on CT, and another patient (2%) had normal findings on one side. Although the vast majority of CF patients do have paranasal sinus abnormalities, we found on CT scan a progression of abnormalities that range from normal sinuses to pansinus disease, and in 74%, bilateral medial displacement of the lateral nasal wall and uncinate process demineralization.

Sinus Disease

Chronic sinus disease in patients with and without cystic fibrosis may have an impact on the pattern of paranasal sinus pneumatization. Arrest of pneumatization has been reported in both of these conditions. To assess the development of the paranasal sinuses in relationship to chronic sinusitis and cystic fibrosis (CF), a retrospective review of coronal CT scans of the age-matched patients with no previous sinus disease, patients with chronic sinusitis, and cystic fibrosis patients was conducted. The patients’ ages ranged from 4 to 17 years. The maxillary sinus volume, anteroposterior diameter, and greatest transverse diameter and height were determined using image analysis software after the coronal CT scans were scanned into Macintosh computer. The size of the maxillary sinus increased with advancing age in the control and chronic sinusitis group, but not in the patients with cystic fibrosis. The patients with cystic fibrosis had a statistically significant smaller maxillary sinus size. Approximately 50% of the patients with chronic sinusitis had anatomic anomalies, the most common being paradoxical middle turbinates. The CT scans of CF patients were characterized by uncinate process demineralization and medial displacement of the lateral nasal wall in the middle meatus, and decreased maxillary sinus pneumatization.

Ciliary Dyskinesia

Background: There is a medial bulging of the lateral nasal wall in patients with cystic fibrosis (CF). Aims: Uncinate process (UP) angulation measurements in patients and controls to objectify this bulging. Materials and Methods: Thirty CF, 17 primary ciliary dyskinesia (PCD), 13 chronic rhinosinusitis with polyps (CRSwp), and 30 controls were included. Angles were measured bilaterally on computed tomography (CT) scans: A, B, C on coronal sections, D and E on axial sections. Angle A was between the UP and the orbit inner wall, whereas the others were between UP and midline. Results: There was no significant difference between controls, PCD, and CRSwp. However, CF had 3 statistically different angles with controls, 5 with CRSwp, and 4 with PCD. Angle A average value was 126° (±16°) in patients with CF, 138° (±19°) in controls ( P = .007), 145° (±15°) in PCD ( P = .001), and 138° (±14°) in CRSwp ( P = .001). Angle E average value was 35° (±10°) in patients with CF, 20° (±6°) in controls ( P < .001), 21° (±4°) in PCD ( P < .001), and 22° (±6°) in CRSwp ( P < .001). Conclusion: Uncinate process’s anatomy is only modified in CF: Angle between UP and inner wall of orbit is closed, and angles between UP and midline are opened. Significance: These measures quantify the medial bulging of lateral nasal wall and support nasofibroscopic observations.

Osteomeatal Complex

Six patients between the ages of 6 and 22 years old with cystic fibrosis were found to have mucoceles of the paranasal sinuses. Four were male and two were female. They experienced nasal obstruction, purulent rhinorrhea, and anosmia, but none had fever or pain. Nasal endoscopy and coronal computerized tomography scans revealed the lateral nasal wall to be displaced medially against the septum. Functional endoscopic sinus surgery revealed large cystic spaces filled with thick yellow-green mucus. Postoperatively most patients are able to smell and breathe through their noses. The mucocele probably begins as an obstructed anterior ethmoid cell, which then enlarges and obstructs the osteomeatal complex, which further impairs drainage of the other sinuses into this area.

Aim: Nasal and paranasal sinus involvement is common in lepromatous leprosy and is of considerable epidemiological significance. The aim of this study was to investigate paranasal sinus abnormalities in treated lepromatous leprosy cases and to evaluate the findings in comparison with those of previous studies.Materials and methods: Thirty-eight patients who had been treated for lepromatous leprosy were included. All patients had been treated with dapsone and rifampicine for six months, and followed with dapsone, rifampicine and clofamizine for a minimum of two years. All patients received a clinical examination, a coronal computed tomography (CT) examination of the paranasal sinuses and ethmoidal sinus endoscopy, in order to investigate the involvement of the paranasal sinuses in the leprosy. Ethmoidal sinus biopsies were taken in 18 of the 21 cases of ethmoidal sinus involvement noted on CT scan.Results: Twenty-three patients had sino-nasal symptoms. Endoscopic examination showed different pathologies in 21 of these patients. Abnormalities in the paranasal CT images were observed in 27 patients. The ethmoidal, maxillary, frontal and sphenoid sinuses were affected in 21, 18, three and two patients, respectively. Various degrees of nasal septum perforation were noted in 18 cases. In six of the 18 patients biopsied, the biopsy specimen showed involvement by lepromatous leprosy.Conclusion: These findings suggest that although these lepromatous leprosy patients had been treated, persistent infection was still commonly encountered. Paranasal sinus CT examination is a useful method for the evaluation of patient response to treatment and follow up; however, a CT scan alone cannot determine whether the leprosy is active.

Paranasal Sinus Disease

Aims and Objectives: The study is carried out with an objective to compare the diagnostic nasal endoscopic findings and radiological appearance in patients with paranasal sinus disease. Methods: 50 cases of chronic sinusitis not responding to routine medical line of treatment were selected and operated after being thoroughly investigated by means of nasal endoscopy and CT scan.  Results: Out of 50 cases, 35 underwent bilateral surgery and 15 underwent unilateral surgery, so a total of 85 procedures were carried out. Findings of both the CT scan as well as diagnostic nasal endoscopy were compared to each other and ultimately correlated with operative findings.  Conclusion: In our study, a high association is found between both the modalities of investigation i.e CT scan and diagnostic nasal endoscopy with one scoring over the other in different parameters. Diagnostic nasal endoscopy is found to be highly sensitive investigatory modality for parameters like frontal recess, spheno-ethmoid recess and hiatus semilunaris, where as CT scan is found to be highly sensitive for parameters like maxillary sinus, uncinate process and posterior ethmoids. So, a case of sinus disease should be diagnosed as early as possible using both these modalities as together they complement each other. Early diagnosis and effective management cures the pathology and prevents disastrous complications.

With the availability of high-resolution computed tomography (CT), a great deal of attention has been paid to the anatomy of the paranasal sinuses. But while investigators have focused on the osteomeatal complex and its relation to chronic rhinosinusitis, there has been little discussion of the superior turbinate. Although a few anatomic studies have tried to quantify pneumatization of the superior turbinate, the prevalence of this finding on radiography is not well addressed in the literature. We prospectively studied 100 consecutively presenting patients who underwent coronal CT of the paranasal sinuses (200 sides) for the evaluation of symptoms of chronic rhinosinusitis at an academic tertiary referral center to determine the prevalence of pneumatization of the superior turbinate. We found evidence of pneumatization in 44 of the 200 sides, for a prevalence of 22%. In all, pneumatized superior turbinates were found in 27 patients (27%)—bilaterally in 17 (17%) and unilaterally in 10 (10%).
