“…Most patients show turbinate hypertrophy by endoscopy compared to the same affection at CT scan [13]. In the current study, the finding of hypertrophic concha was more evidenced in CT scan compared to sinus endoscopy (43.75 vs. 40 %).…”

Sinonasal endoscopy is an essential part of the rhinologic examination performed by otolaryngologists in the evaluation of sinonasal disease. The use of the endoscopes has been popularized with the advent of endoscopic sinus surgery. To evaluate the role of nasal endoscopy as primary examination in the early and accurate diagnosis of sinonasal diseases in comparison to other diagnostic tools in rhinology. A retrospective and prospective study was carried out on 200 patients with clinical evidence of sinonasal diseases. They were evaluated with anterior rhinoscopy, nasal endoscopy and CT paranasal sinus. The level of agreement between anterior rhinoscopy and nasal endoscopy was substantial for deviated nasal septum, inferior turbinate hypertrophy and polyp (0.735, 0.712 and 0.709, respectively), but moderate for middle turbinate hypertrophy (0.418). The results of endoscopy and CT comparison among 80 patients, whose symptoms warranted CT, indicated that although for most of the findings, there was almost perfect to substantial level of agreement between the results of the two methods, five patients had normal CT imaging report, while they demonstrated early polyps during endoscopic evaluation. Also, CT missed 4 cases of deviated nasal septum. Diagnostic nasal endoscopy proved a better technique to detect various sinonasal pathologies as well as anatomical variations, which are otherwise missed on Computed Tomography or inaccessible on anterior rhinoscopy especially in the key area comprising the ostiomeatal complex. We reinforce the fact that it should be viewed as an essential part of a complete examination of the nose and sinuses.

Background: Paranasal sinus diseases are one of the commonest causes of patients visit to an Otorhinolaryngologist. The symptoms are multiple and vague, while an examination is often limited as sinuses cannot be examined directly. Anterior rhinoscopy gives little information about middle meatus and osteomeatal unit. Objective: The study was carried out with an objective to compare the Diagnostic nasal endoscopic findings and radiological appearance in patients with paranasal sinus disease. Methods: This study included twenty four patients with chronic sinusitis resistant to medical treatment for a period not less than six weeks. The study work was done in Otorhinolaryngology Department in Zagazig University Hospitals for a duration from August 2016 to October 2017. Results: Patients' age ranged from 20 to 58 years with a mean of 32.6 ± 10.68. They were 6 males and 18 females. These patients were divided into two groups: The first group does CT 1-3 months before surgery. The second group repeats CT at the day before operation. Then detection of correlation between CT and intra operative endoscopy findings in both groups. Interpretation and conclusion: In our study, a high association is found between both the modalities of investigation , i.e. CT scans and Diagnostic nasal endoscopy with one scoring over the other in different parameter. Diagnostic nasal endoscopy is found to be highly sensitive investigatory modality for parameters like frontal recess, spheno-ethmoid recess and hiatus semilunaris, whereas 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.

“…Computed tomography (CT) is one of the most important diagnostic tools in medicine, with a wide scope for clinical use [4, 5]. In 2009, Brazil had 15.6 CT scanners (CTs) per million people, a density comparable to Canada (14.2) and New Zealand (15.8).…”

Objective This study evaluated the productivity of computed tomography (CT) models and characterized their simplest (entry-level) models' supply in the world market. Methods CT exam times were measured in eight health facilities in the state of Rio de Janeiro, Brazil. Exams were divided into six stages: (1) arrival of patient records to the examination room; (2) patient arrival; (3) patient positioning; (4) data input prior to exam; (5) image acquisition; and (6) patient departure. CT exam productivity was calculated by dividing the total weekly working time by the total exam time for each model. Additionally, an internet search identified full-body CT manufacturers and their offered entry-level models. Results The time durations of 111 CT exams were obtained. Differences among average exam times were not large, and they were mainly due to stages not directly related to data acquisition or image reconstruction. The survey identified that most manufacturers offer 2- to 4-slice models for Asia, South America, and Africa, and one offers single-slice models (Asia). In the USA, two manufacturers offer models below 16-slice. Conclusion Productivity gains are not linearly related to “slice” number. It is suggested that the use of “shareable platforms” could make CTs cheaper, increasing their availability.

Nasal endoscopy associated with paranasal sinus computerized tomography scan in the diagnosis of chronic nasal obstruction

Abstract: Thus, the presented study and the results of nasal fossa findings obtained by nasal endoscopy were more conclusive in the elucidation of diagnosis than those obtained by computer tomography of the paranasal sinus.
