RESUMO
Objectives: To (i) identify the prevalence of dental disease, (ii) identify the proportion of sinusitis cases that could be considered odontogenic in origin and, (iii) audit the rate of diagnosis of incidental dental disease and odontogenic sinusitis in radiology reports on CT scans covering the maxillary teeth and sinuses. Materials and methods: Images and reports of CT studies performed in our institution that covered the paranasal sinuses and maxilla were retrospectively audited for documentation of findings pertaining to maxillary sinusitis and maxillary dental disease. Trauma cases, edentulous and pediatric patients and patients without maxillary sinusitis or dental disease were excluded. The etiologies of maxillary sinusitis was defined as likely odontogenic, indeterminate and rhinogenic sinusitis. Only molar and pre-molar tooth disease were considered as these are most commonly in direct contact with the floor of the maxillary sinus. Results: One-hundred sixty CT studies were reviewed. The prevalence of dental caries and periapical lucency was 80.6% and 15.0%, respectively. The cause of sinusitis was determined to be likely odontogenic in 30.0%, rhinogenic in 33.1% and of indeterminate origin in 36.9%. The rate of reporting dental findings or raising the suspicion of odontogenic sinusitis was 8.5% (n = 14). Conclusions: Under-reporting of dental disease and odontogenic sinusitis is common. Early recognition results in higher chances of salvaging the diseased tooth, preventing complications and providing appropriate treatment. An urgent and collective effort by the radiological fraternity is warranted to recognize the significance of reporting of dental pathologies, even in CT scans done for other indications.
RESUMO
BACKGROUND: As more evidence comes to light that hamstring harvesting may not be as benign a procedure as previously thought, considerable interest is being generated towards corelating the knee flexural strength deficits with the degree of tendon regeneration. The current study aimed to corelate knee flexion strength deficits with ultrasonographically quantified degree of hamstring regeneration after tendon harvest. STUDY DESIGN: 31 patients of ACL reconstruction with hamstring grafts were divided into 2 groups (6 months and 1-year post op) according to time of follow up. Ultrasonography of both the knees to assess Semitendinosus tendon dimensions was done. Regeneration was classified as non-significant, mild (Zone 1, till 4 cm above the lateral joint line), moderate (Zone 2 ,at the level of the lateral joint line) and significant (Zone 3, 1.5 cm below the lateral joint line) as the regenerate happens from proximal to distal. Regenerate dimensions were compared with US measurements from the opposite knee. Bilateral isokinetic strength tests of the knees were done to evaluate flexion strength, and strength deficits were compared with degree of tendon regeneration. RESULTS: 14 (45%) of cases had no regeneration at both time periods. 7 patients (41%) in the 6-month post-op group showed some form of regeneration, and 10 patients (71%) in the 1-year post-op group showed regeneration. 29/31 patients had some flexion strength deficit. Strength deficit correlated with the level and degree of tendon regeneration, with non-significant regeneration cases showing higher strength deficit (mean - 28.51%), and cases with significant regeneration showing least amount of strength deficit (mean - 3.66%). CONCLUSION: Flexion strength deficits after hamstring harvest are significant and corelate with degree of tendon regeneration, which improves over time. US is adequate to quantify degree of tendon regeneration, which in turn can help prognosticate return of flexion strength.
