“…However, it is more consistent with robust systematic reviews assessing CT imaging of bony invasion in SCC of the oral cavity, for example in Bombeccari et al where CT is reported to have a LRþ of 14.8 and LRÀ of 0.4. 27 It is unclear why our findings differ so drastically from Kadakia et al's, but their study included only immunocompromised patients, with an average age 11.7 years younger than our cohort (63.2 years compared to our 74.9), and had a much more even male:female ratio (29:24, compared to 29:10 in our study). Kadakia et al also did not investigate CT scan accuracy as a primary aim.…”

Objectives The aim of this study was to ascertain the accuracy of computed tomography (CT) in assessing the presence of bony involvement and thickness of squamous cell carcinoma (SCC) of the scalp. Methods A single-centre retrospective chart review was carried out. Inclusion criteria were scalp SCC, CT between January 2008 and 2018, and the availability of a reference test. Reference tests were either histology, surgical notes or clinical notes. Tabular assessment of accuracy was performed and Student’s t-test, Mann–Whitney U test and Fisher exact test were used in univariable analysis. Accuracy of thickness measurement was calculated using the limits of agreement method, and linear regression was used to examine trend. Results Thirty-nine patients were included. Most patients were male (74.4%), white (97.4%), not immunosuppressed (66.6%) and had poorly differentiated tumours (33.3%). The most common tumour sites were the vertex (28.2%) and temporal region (23.1%). Sensitivity of CT in detecting presence or absence of bony invasion of scalp SCC was 76.9% (95% CI 46.2–94.9%) and specificity was 96.2% (95% CI 80.4-99.9%). Overall accuracy was 89.7% (95% CI 75.8–97.1%), positive predictive value was 90.1% (95% CI 58.7–99.8%) and negative predictive value was 89.3% (95% CI 71.8–97.7%). No significant differences were found comparing patients with an accurate or inaccurate CT scan. Thickness on CT was found to be consistent with histological thickness at the 95% confidence level. Conclusions CT is accurate at assessing the presence of bony involvement and thickness of scalp SCC. This study was limited somewhat by small sample size.

Lip cancers are the second most common cancers of head and neck region. Due to its functional and aesthetic consequences and aggressive course, clinical approach including surgical margins, type of neck dissection and reconstruction techniques are debated topics in lip cancer. We investigated reliability of preoperative evaluations, pathological risk factors for recurrence or metastasis, surgery related morbidities and their management. Material and Method:The records of patients with basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) were reviewed retrospectively. Demographic data of the patients were evaluated, the reliability of the punch biopsy and radiological imaging was discussed and the effects of pathological features on the risk of recurrence and metastasis was investigated. Surgery related morbidities were revealed. All these problems and their solutions were discussed in the light of literature.Results: Punch biopsy was found unreliable in this study. Relapses were associated with advanced stage and perineural invasion while cervical metastasis was related with the size of the specimen and surgical margins. Donor site morbidities were higher in local flaps. Recurrence or metastases were not observed in patients who were treated with extensive excision, neck dissection and reconstruction with free flap. Conclusions:Early diagnosis and functional and aesthetic repair are the most important factors in terms of prognosis in lip cancer. First surgery is very important that determines the prognosis. As the stage progresses, the surgery becomes complex but prognosis can be as good as early stages with good clinical approach.

This study compared the acquisition protocols of the Conical Beam Computed Tomography (CBCT) system, to assess the influence on image accuracy by different voxel sizes and the presence of soft tissue. Tomographic acquisition was performed in a fresh (F) and dry (D) pork jaw with voxel sizes of 0.4, 0.3 and 0.25 mm. The gold standard was obtained by scanning dry jaws covered with barium sulfate with a voxel size of 0.25 mm. The images were treated in the MIMICS® program, and noise areas were removed manually, using a fixed threshold for the purpose of generating 3D printing windows. Each window was virtually overlaid with the gold standard using the MeshLab software, obtaining absolute error values between the meshes, generating a map of discrepancies. Significant differences were found between windows D 0.30 vs. F 0.30, D 0.30 vs. F 0.25, D 0.30 vs. D 0.25, D 0.30 vs. F 0.40, F 0.30 vs. D 0.25, F 0.25 vs. D 0.25, F 0.25 vs. D 0.40, D 0.25 vs. F 0.40, D 0.25 vs. D 0.40 and F 0.40 vs. D 0.40, (p <0.05). It was observed that the dry jaw windows showed a lower mean and standard deviation when compared to the fresh jaw windows. The 0.25 mm voxel protocol showed the most accurate result and the presence of soft tissues influenced the accuracy of the image when some protocols were compared statistically.
