Effectiveness of caudal septal extension graft application in endonasal septoplasty

Abstract Introduction Septal deviation is a common disease seen in daily otorhinolaryngology practice and septoplasty is a commonly performed surgical procedure. Caudal septum deviation is also a challenging pathology for ear, nose, and throat specialists. Many techniques are defined for caudal septal d...

Which features of advanced head and neck basal cell carcinoma are associated with perineural invasion?

Abstract Introduction Perineural invasion is a unique route for tumor dissemination. In basal cell carcinomas, the incidence is low, but increases in advanced cases. Its importance is recognized but not fully understood. Objective To compare head and neck basal cell carcinomas with and without perineur...

Human papillomavirus in oral cavity and oropharynx carcinomas in the central region of Brazil

Abstract Introduction Molecular studies about carcinomas of the oral cavity and oropharynx demonstrate the presence of human papilomavirus genome in these tumors, reinforcing the participation of human papilomavirus in oral carcinogenesis. Objectives This study aimed to determine the prevalence of huma...

The role of Onodi cells in sphenoiditis: results of multiplanar reconstruction of computed tomography scanning

Abstract Introduction Onodi cells are the most posterior ethmoid air cells and extend superolateral to the sphenoid sinus. These cells are also intimately related with the sphenoid sinus, optic nerve, and carotid artery. Radiologic evaluation is mandatory to assess for anatomic variations before any tre...

Three dimensional evaluation of alveolar bone changes in response to different rapid palatal expansion activation rates

ABSTRACT Introduction: The aim of this multi-center retrospective study was to quantify the changes in alveolar bone height and thickness after using two different rapid palatal expansion (RPE) activation protocols, and to determine whether a more rapid rate of expansion is likely to cause more adverse...

The percentage of resected and ischemic volume determined by a geometric model is a significant predictor of renal functional change after partial nephrectomy

Int. braz. j. urol; 43 (1), 2017
ABSTRACT Purpose The percentage of parenchyma preserved plays a predominant role in predicting renal function after partial nephrectomy (PN). Currently there is no standard method to estimate preserved renal parenchyma. In this study we propose a formula of the percentage of resected and ischemic volum...

Can neutrophil to lymphocyte ratio predict lamina propria invasion in patients with non muscle invasive bladder cancer?

Int. braz. j. urol; 43 (1), 2017
ABSTRACT Objective Recent studies have demonstrated the role of systemic inflammation in the development and progression of cancer. In this study, we evaluated whether preoperatively measured neutrophil-to-lymphocyte ratio (NLR) can predict lamina propria invasion in patients with non-muscle-invasive b...

Artificial urinary sphincter for urinary incontinence after radical prostatectomy: a historical cohort from 2004 to 2015

Int. braz. j. urol; 43 (1), 2017
ABSTRACT This study aimed to retrospectively evaluate a cohort of patients with prostate cancer and persistent urinary incontinence after radical prostatectomy. From January 2004 to December 2015, eighty-six individuals were identified to have received an AUS implant, provided by a private nonprofit HMO ...

Predictive role of Trimprob associated with multiparametric MRI in the diagnosis of prostate cancer

Int. braz. j. urol; 43 (1), 2017
ABSTRACT Objectives To evaluate the predictive value of TRIMprob test to detect prostate cancer (PCa) in patients referred to prostate biopsy (PB). Material and Methods Patients with PSA <10ng/mL and rectal exam without findings suggestive of prostate cancer were selected for TRIMprob evaluation. ...

One - staged reconstruction of bladder exstrophy in male patients: long - term follow-up outcomes

Int. braz. j. urol; 43 (1), 2017
ABSTRACT Introduction The surgical correction of bladder exstrophy remains challenging. In our institution, the repair has evolved from a staged repair to one-stage reconstruction. The one-stage reconstruction includes; bladder closure, Cantwell-Ransley neourethroplasty and abdominoplasty using groin f...
