<p class="abstract"><strong>Background:</strong> Deviated nasal septum (DNS) is one of the most frequent causes of nasal obstruction in adults. An anterior rhinoscopy (AR), which is usually the first diagnostic procedure in the evaluation of obstructive nasal pathologies, is often inadequate in the assessment of the posterior nasal cavity and the gold standard method for the evaluation of paranasal anatomy and inflammatory paranasal sinus pathologies is paranasal sinus computed tomography (PNS CT). Aim was to validate the recommendation of pre-operative computed tomography scan in minimizing post-septoplasty complications.</p><p class="abstract"><strong>Methods:</strong> A retrospective record based study was conducted including all patients with clinically diagnosed DNS and undergone surgical intervention at Khamis Mushayet General Hospital. Data extracted included patients demographic data, and post-operative recorded complications and history of preoperative CT scan for evaluating and grading DNS.  </p><p class="abstract"><strong>Results:</strong> A total sample of 60 patients’ undergone septoplasty for DNS. Patients who undergone preoperative CT were 30. The remaining 30 patients didn’t undergone pre-operative CT for evaluation of DNS. The most diagnosed complication was nasal obstruction (28.3%) followed by external nose deformity (20%). Exact of 47% of patients had postoperative nasal obstruction didn’t undergone pre-operative CT. About 42% of those who had postoperative nasal deformity didn’t undergone CT while 33% of patient who had post-operative bleeding and septal perforation didn’t undergone CT.</p><p class="abstract"><strong>Conclusions:</strong> In conclusion, the study revealed that preoperative CT showed insignificant efficacy in relieving nasal obstruction or minimizing postoperative complications.</p>

Bonebridge (BB) is the first active implantation system for bone conduction that is placed fully under the skin. Experience suggests that BB is characterized by low incidence of postoperative complications. This case report presents a rare case of a 16-year-old girl with incidence of emphysema occurring over the implant 1 year after operation. We performed a computed tomography scan that showed pockets of gas above the floating mass transducer so we provided the revision surgery and sealed the artificial opening with fat from the earlobe and fibrin glue. Since that time, no air has collected in the retroauricular area and the implant has been fully functional.

Tomography Scan

Background: Thorax MSCT examination is a diagnostic imaging that is capable of displaying both normal and pathological lung and respiratory organs. MSCT examination also has a better level of sensitivity and specificity compared to other modalities, but the radiation exposure given is very high, so the radiation dose given to patients is high. The reduction in radiation dose is very important because of the direct exposure to sensitive tissue. One method of reducing radiation dose is by reducing the tube voltage. However, the decrease in tube voltage causes a decrease in image quality as indicated by increased noise and decreased CNR. To maintain the quality of the image at low tube voltage setting, an IR reconstruction of SAFIRE was used. The purpose of this research is to know the impact of using SAFIRE on dose radiation and image quality of thorax MSCT.Methods: This study was an experimental study with a quasi-experimental study design. The object used was the N-1 Lungman chest phantom in which an artificial tumor was attached. Radiation dose assessment used CTDI value, while image quality assessment used noise and CNR. Data processing was conducted using linear regression test.Results: There was an effect of tube voltage setting and SAFIRE setting on radiation dose and image quality.Conclusions: Tube voltage ssetting and SAFIRE setting had an effect on radiation dose and image quality. Tube voltage setting and SAFIRE strength level setting that were able to provide optimal radiation dose and image quality were tube voltage of 80 kVp and SAFIRE strength levels 3 and 4 (S3 and S4).

Background: Gallstone ileus is defined as a mechanical obstruction due to impaction of one or more gallstones within the gastrointestinal tract. The pathogenesis is due to the presence of a cholecystoduodenal fistula. Material and methods: We conducted a descriptive and retrospective study of five cases of gallbladder ileus between December 2017 and January 2020. Sex, age, clinical presentation, usefulness of computed tomography scan, surgical approach and treatment, surgeon, site of obstruction, gallstone size and mortality were analyzed. Results: A total of five patients were included; mean age was 66 years. Four patients presented bowel obstruction and one patient had bowel perforation. All the patients underwent computed tomography scan and laparotomy. Enterolithotomy was performed in four patients and one patient underwent bowel resection. One patient died. Conclusion: Gallstone ileus is a rare condition more likely to affect women. Computed tomography scan is the gold standard method for the diagnosis. The surgical approach and strategy will depend on patient-related factors and on the experience of the surgical team.
