Purpose Skeletal muscle mass (SMM) depletion and sarcopenia as predictors of postoperative complications and poorer overall survival (OS) have been validated in many surgical fields through cross-sectional imaging (CT, MRI), with potential limitations. We evaluated it in a stage III-IV head and neck squamous cell carcinoma (HNSCC) surgical cohort through ultrasound (US) of rectus femoris muscle (RF), a quick, cheap, repeatable alternative. Methods Patients submitted to surgical treatment with curative purpose were recruited and prospectively evaluated through clinical, biometric, biochemical, surgical, pathological and functional prognosticators and with preoperative US of RF with regards to 30-day complications and OS. Results Forty-seven patients completed the study. RF cross-sectional area (RF-CSA) was used to identify patients with low SMM (CSA ≤ 0.97 cm2 18/47, 38.3%). RF-CSA was lower in complicated cases (0.95 ± 0.48 vs 1.41 ± 0.49 cm2; p = 0.003), remaining the only independent predictor of postoperative complications at multivariate analysis, with a model including ASA score and modified Frailty index (OR 9.84; p = 0.004). SMM depletion significantly impaired OS (13.6 ± 2.9 vs 26.3 ± 2.1 months; p = 0.017), being its only independent prognosticator at multivariate Cox regression analysis (OR 4.42; p = 0.033). Conclusion RF-CSA, evaluated with US, seems a reliable method for identification of patients with low SMM in a stage III-IV HNSCC cohort, defining a subset at high-risk of 30-day complications and poorer OS.Objective Stapes surgery is the gold standard surgical treatment nowadays for otosclerosis. Several controversies on the procedure have been reported; surgical techniques for most favorable outcomes are still on discussion. The objective of this study is to present an update of evidence-based medicine concerning the utilization of lasers and drilling for footplate fenestration during stapedotomy surgery. A systematic review and meta-analysis were conducted. Materials and methods Publications in English in the last 5 years were searched in the PubMed/MEDLINE database and were systematically reviewed. A total of three articles were included according to the inclusion criteria, obtaining a total of 1531 patients managed surgically for otosclerosis, using laser or drill for footplate fenestration. Data were systematically extracted and hearing results were compared in a meta-analysis. Results For the drill group, a total of 978 patients were retrieved and data were obtained as follows mean age was 50 years old; the female proportion was 62%; mean preoperative air-bone gap (ABG) of 28 dB; mean postoperative ABG of 8 dB; mean ABG improvement of 20 dB; an ABG closure rate to less then 10 dB of 74%. NF-κΒ activator 1 supplier For the laser group, a total of 553 patients were retrieved, data were obtained as follows mean age was 47 years old; the female proportion was 63%; preoperative ABG of 26 dB; postoperative ABG of 8 dB; mean ABG improvement of 18 dB; an ABG closure rate to less then 10 dB of 72%. Conclusion The results from this study reveal that in regard to postoperative hearing results, surgical outcomes are comparable, and there is no statistically significant difference between the utilization of drills and lasers as a surgical instrument for the fenestration of the stapes footplate during stapedotomy surgery.Purpose Adenotonsillectomy is the first-line treatment for pediatric obstructive sleep apnea (OSA). However, although completely resolved OSA after adenotonsillectomy, some children still showed persistence of mouth breathing. Therefore, we attempted to identify risk factors for residual mouth breathing in children with OSA after successful adenotonsillectomy. Materials and methods This study retrospectively enrolled children who underwent adenotonsillectomy as a treatment of OSA. Additionally, children who showed apnea-hypopnea index ≥ 1 on 1-year postoperative polysomnography or adenoid regrowth on one-year postoperative lateral cephalogram were excluded. The presence of allergic rhinitis, septal deviation, dentofacial abnormalities, the size of tonsil and adenoid was also evaluated in all enrolled children. Dentofacial abnormalities were defied as a high palatal arch, macroglossia, retrognathia, micrognathia, and overcrowding of teeth which assessed by dentists. Results A total of 62 children were enrolled (no residual mouth-breathing group, n = 18 and residual mouth-breathing group, n = 44) in this study. There were no significant differences in demographic factors, physical examination, and sleep parameters, except age and preoperative adenoid size. On the multiple logistic regression analysis, we found that older age, large adenoid size, and presence of dentofacial abnormalities significantly correlated with residual mouth breathing (adjusted coefficient estimates = 0.3890, 2.3611, and 2.8615, respectively) after successful adenotonsillectomy. Conclusions Older age, large adenoid size, and presence of dentofacial abnormalities in children with OSA may be the risk factors for residual mouth breathing after successfully resolved OSA.Purpose Most studies regarding residual and recurrent cholesteatoma focus on single relapse. This study examines patients who had to undergo at least three surgeries for complete eradication of their cholesteatoma, with the aim of bringing to light risk factors and assessing the functional impact of multiple surgeries on hearing. Method We include 27 patients who underwent 3 consecutive surgeries for cholesteatoma between 2006 and 2016. This population represented 3.1% of all cholesteatoma operated on during that same period (868 patients). Results Cases of multi-residual and/or recurrent cholesteatoma (RRC) were significantly younger (13.1 years old), than single-RRC or cases with No-RRC (respectively, 28.0 and 38.5 years old) (p less then 0.01). Furthermore, there was a significant difference in cholesteatoma location especially for combined attical and mesotympanic location between the three groups (no-RCC 26%; single-RRC 34% and multi-RRC 66%) (p less then 0.01). There was also a significant difference in ossicular erosion of the malleus, incus and stapes between the three groups (p less then 0.
