Online ahead of print. ABSTRACT PURPOSE: Sinus tympani is the space in the retrotympanum, with variable morphology. Computed tomography is a common tool to investigate sinus tympani anatomy. During cochlear implantation or tympanoplasty, electrocochleography can be used for hearing monitoring. In such a surgical strategy the electrode is placed in the round window's region throughout posterior tympanotomy. Commo n accessible needle-shaped electrodes using is difficult in achieving intraoperative stabilization. The aim of the study is to assess the dimensions and shape of sinus tympani, basing on the micro computed tomography scans for purposes of establishing the possible new electrocochleography electrode shape. MATERIALS AND METHODS: Sixteen fresh frozen cadaveric temporal bones were dissected. MicroCT measurements included the depth and the width of sinus tympani, width of facial canal with stapedius muscle chamber. Obtained data were analyzed statistically with the use of RStudio 1.3.959 software. RESULTS: The highest average width of sinus tympani amounted for 2.68 mm, depth measured at the round window plane for 3.19 mm. Width of facial canal with stapedius muscle chamber highest average values at the round window plane- 3.32 mm. The lowest average minimum and maximum values were calculated at the 1 mm above the round window plane. The highest average posterior tympanotomy width was 2.91 mm. CONCLUSIONS: The shape of the tympanic sinus is like a trough with the narrowest and deepest dimensions in the middle part. The ST shape and dimensions should be taken into account in constructing the ECochG electrode, designed for optimal placement through posterior tympanotomy approach.

Long-term hypocalcemia prediction post thyroidectomy

xlomafota13 shared this article with you from Inoreader Long-term hypocalcemia prediction post thyroidectomy Via Thyroid Res Pract Deepak Janardhan, Sandeep Suresh, PG Balagopal, Nebu Abraham George, KM Jagathnath Krishna Thyroid Research and Practice 2021 18(1):14-18 Introduction: Hypocalcemia is a common sequela of total thyroidectomy and is usually transient (30%), only a few develop permanent hypoparathyroidism. Till date, no effective risk stratification score to predict hypocalcemia is available that can predict postoperative hypocalcemia. Materials and Methods: This was a prospective observational study including all patients who underwent total or completion thyroidectomy with initial parathormone (PTH) within the normal range in our institution during a 1 year period. Postoperative 6th h PTH fall was noted in all patients and cutoff point for the prediction of long-term hypocalcemia (LTHP) was determined using a paired t-test. Results: Postoperatively, calcium supplementation was initiated in 52% of patients. In 7.6% of patients who had a fall in PTH to more than 80% of preoperative value, calcium supplementation could not be tapered even after 3 months postoperatively. About 66% of patients <20 years of age developed hypocalcemia in the postoperative period. Patients who developed delayed hypocalcemia with initial normal calcium levels had fall in PTH of at least 45%. For individuals below 20 years, a PTH fall of 56% or more required calcium supplementation. The various variables studied failed to attain statistical significance. Conclusions: More than 82% fall in 6th h postoperative PTH predicts long-term hypocalcemia. Post total thyroidectomy, adolescent individuals are at a higher risk of developing hypocalcemia; hence, early calcium supplementation is recommended based on fall in PTH. Weighted score to predict LTHP could not be developed, as none of the risk factors evaluated were statistically significant. View on the web Inoreader. Take back control of your news feed.

Acute suppurative thyroiditis: An unusual complication

xlomafota13 shared this article with you from Inoreader Acute suppurative thyroiditis: An unusual complication Via Thyroid Res Pract Dipratim Das, Partha Chakraborty, Madhurima Ganguly, Pankaj Kumar Halder Thyroid Research and Practice 2021 18(1):37-39 Acute thyroiditis is rare and usually subsides with medical therapy. An abscess arising due to it is even rarer. Sometimes, surgical drainage is required to control ongoing infection and sepsis. We report a case of a 4-year-old girl who had acute suppurative thyroiditis. The swelling was not resolving after 9 days of administering intravenous antibiotics and eventually compressing the esophagus and trachea which was relieved leading to a speedy recovery on emergency surgical drainage.

The never-ending battle between proximal row carpectomy and four corner arthrodesis: A systematic review and meta-analysis for the final verdict

xlomafota13 shared this article with you from Inoreader The never-ending battle between proximal row carpectomy and four corner arthrodesis: A systematic review and meta-analysis for the final verdict Via Journal of plastic, reconstructive & aesthetic surgery : JPRAS J Plast Reconstr Aesthet Surg. 2021 Oct 23:S1748-6815(21)00516-7. doi: 10.1016/j.bjps.2021.09.076. Online ahead of print. ABSTRACT While scaphoid excision combined with Four Corner Arthrodesis (FCA) or Proximal Row Carpectomy (PRC) is a commonly-used salvage procedures to treat type two and type three Scapholunate Advanced Collapse (SLAC) and Scaphoid Nonunion Advanced Collapse (SNAC)-induced degenerative arthritis, controversy remains over which treatment intervention provides superior outcomes. We searched for articles comparing a range of motion, grip strength, complications requiring reoperation, conversion to wrist arthrodesis, pain, and disability of shoulder and arm scores between FCA and PRC-treated patients. The risk of bias was assessed using the National Institutes of Health (NIH) quality assessment tool. We performed a meta-analysis using Random-Effects Models. Fifteen articles (10 retrospective, 2 cross-sectional, 1 prospe ctive, and 2 randomized trials) were included. There was no significant difference between PRC and FCA in any of the different outcome measures. The risk of bias was found consistently high across all studies. Despite the lack of high-quality evidence, based on existing literature, we recommend PRC as the preferred choice of treatment because of the simplicity of the surgical procedure, lack of hardware-related complications, and comparable long-term outcomes. Level of evidence: III - Therapeutic. PMID:34802951 | DOI:10.1016/j.bjps.2021.09.076 View on the web Inoreader. Take back control of your news feed. Follow us on Twitter and Facebook.

Oral squamous cell carcinoma outcome in adolescent/young adult: Systematic review and meta‐analysis

xlomafota13 shared this article with you from Inoreader Oral squamous cell carcinoma outcome in adolescent/young adult: Systematic review and meta‐analysis Via Head & Neck Abstract To perform a systematic review focusing on the prognosis of oral cavity squamous cell carcinoma (OSCC) in young patients (≤40 years old) compared to older (>40 years old). Four databases were used in our search strategy. First, all titles were systematically organized using the Covidence platform online. In the second phase, 118 full texts of potentially eligible studies were analyzed by reviewers independently and in pairs. Twelve studies were considered eligible for data extraction. The relapse was higher in the young than in controls (pooled relative risk (RR) = 1.31; 95% CI [1.10–1.56]). The 5-year disease-free survival (DFS) was worse in young group (pooled hazard ratio (HR) = 0.73; 95% CI [0.63–0.85]) but the 5-year overall survival (OS) estimate was similar between the groups (pooled HR = 0.84; 95% CI [0.70–1.00]). While the 5-year OS was similar between groups, the number of relapses and 5-year DFS were worse in patients with OS CC ≤40 years old. View on the web Inoreader. Take back control of your news feed.
