Uncinate process deviation in patients with odontogenic sinusitis: a computed tomographic evaluation

The uncinate process of the ethmoidis is one of the anatomic boundaries of osti- omeatal complex. Its relationship with the maxillary sinus ostium makes it the key landmark for endoscopic sinus surgery. Many authors denied a direct role of the uncinate process in the development of sinonasal infections (1). Nevertheless, chronic sinonasal diseases are often accompanied by an uncinate process antero-medialization, most notably in presence of an odontogenic etiology. This study aimed to retrospectively analyze uncinate process anatomy on computed tomographic (CT) scans, defining the association between uncinate process inclination and sinonasal health status. Sinonasal CT examinations of 46 individuals were reviewed, comparing patients without clinical and radiographic signs of sinonasal diseases (Group I), and patients diagnosed with odontogenic sinusitis according to the criteria proposed by Felisati et al. (2)(Group II). Uncinate process inclination was calculated by Radiant Dicom Viewer software, as the angle between the straight line connecting the antero- superior and the postero-inferior part of uncinate process, and the axis of symmetry, passing through sphenoidal rostrum and perpendicular to bizygomatic line. For each patient three axial scans (the most cranial, median, the most caudal), in which uncinate process was clearly detectable, were selected and a mean value was computed. Descriptive statistics of uncinate process inclination were calculated separately in the two groups. In Group I the mean angle was13.18° ± 10.33°with confidence limits (CL) (99%) between 6.21° and 20.15°,in Group II the mean angle was 29.89°±9.56° with CL between 24.44° and 35.34°. From these preliminary results, a marked medial devia tion of uncinate process was identified in odontogenic sinusitis compared to healthy sites. Additional assessments are required to confirm the role of this anatomical varia- tion in the pathogenesis of odontogenic sinusitis

Endaural microscopic approach versus endoscopic transcanal approach in treatment of attic cholesteatomas.

peer reviewed[en] PURPOSE: Compare the audiological results and postoperative outcomes of the endoscopic approach versus the endaural microscopic approach for treatment of attic cholesteatomas, using a randomized prospective model. MATERIALS AND METHODS: Eighty patients were consecutively enrolled in the study and randomized into two groups of treatment of 40 patients: Group A -tympanoplasty with a microscopic endaural approach; Group B -tympanoplasty with an exclusive trans-meatal endoscopic approach. Preoperative, intraoperative and postoperative outcomes were evaluated. Hearing was assessed preoperatively and at 1 month, 3 months and 6 months after surgery in both groups. RESULTS: There were no differences in the parameters analyzed (CT findings, patient age, disease duration, intraoperative cholesteatoma characteristics,) between the group A and B patients. No statistical difference between the two groups regarding hearing improvement, abnormal taste sensation, dizziness, post-operative pain and healing times emerged. Graft success rate was 94.5 % and 92.1 % for MES and ESS respectively. CONCLUSION: Both microscopic and exclusively endoscopic endaural approaches offer similar and excellent results in the surgical treatment of attic cholesteatomas

The impact of immediate breast reconstruction on the time to delivery of adjuvant therapy: the iBRA-2 study

Background: Immediate breast reconstruction (IBR) is routinely offered to improve quality-of-life for women requiring mastectomy, but there are concerns that more complex surgery may delay adjuvant oncological treatments and compromise long-term outcomes. High-quality evidence is lacking. The iBRA-2 study aimed to investigate the impact of IBR on time to adjuvant therapy. Methods: Consecutive women undergoing mastectomy ± IBR for breast cancer July–December, 2016 were included. Patient demographics, operative, oncological and complication data were collected. Time from last definitive cancer surgery to first adjuvant treatment for patients undergoing mastectomy ± IBR were compared and risk factors associated with delays explored. Results: A total of 2540 patients were recruited from 76 centres; 1008 (39.7%) underwent IBR (implant-only [n = 675, 26.6%]; pedicled flaps [n = 105,4.1%] and free-flaps [n = 228, 8.9%]). Complications requiring re-admission or re-operation were significantly more common in patients undergoing IBR than those receiving mastectomy. Adjuvant chemotherapy or radiotherapy was required by 1235 (48.6%) patients. No clinically significant differences were seen in time to adjuvant therapy between patient groups but major complications irrespective of surgery received were significantly associated with treatment delays. Conclusions: IBR does not result in clinically significant delays to adjuvant therapy, but post-operative complications are associated with treatment delays. Strategies to minimise complications, including careful patient selection, are required to improve outcomes for patients

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries
