Imaging Update of Congenital Hearing Loss: A Recent Insight Imaging Including 3D MRI Cisternography Prior to Cochlear Implant.

SNHL in children is an important issue. Cochlear implant is a highly technological device that is surgically inserted in the cochlea to solve this issue. To evaluate types of anomalies of the inner ear in children with sensorineural hearing loss in a tertiary care hospital and confirm that the routine MRI, MR cisternography and HRCT provides the surgeon with the imaging finding and criteria of patients candidates for CI. Patients and method: 600 patients with SNHL underwent HRCT and MRI. CT examinations were normal in 457 patients (76.2%) and 143 patients (23.8%) with inner ear anomalies. MRI examinations were normal in 440 patients (73.3%) and had inner ear anomalies in 160 patients (26.7%). 3D bFFE and 3D DRIVE was summarized. The 3D bFFE sequence was statistically significantly better than the 3D DRIVE for the demonstration of the cochlear vestibule. Superior, inferior vestibular nerves and facial nerves while 3D DRIVE is superior to 3D bFFE in the visualization of the semicircular canals. HRCT and MRI provide accurate anatomical delineation of complex inner ear structures and 3D improves pre-implant evaluation.

Stability and Clinical Outcomes of Angle Fracture Fixation Using Sagittal Split Plate (SSOP) Versus Two Miniplates: Randomized Clinical Trial.

The aim of this study was to compare the stability and clinical outcomes between the two miniplates and sagittal split plate (SSOP) in angle fracture fixation. Thirty-eight patients with a mandibular angle fracture were selected and divided randomly into two groups. Intervention was treated with SSOP, and the control group was treated with conventional two miniplates. Clinical evaluation included occlusion, edema, nerve affection, wound dehiscence and mouth opening. Radiographic parameters included the measurement of inter-ramus distance, inter-mental distance and bone density. All clinical parameters were evaluated at one week, one month and three months intervals. Radiographic parameters were evaluated immediately postoperative, and after three months. Results showed that SSOP had less postoperative complications (10.50%) than the two miniplates (31.60%). It can be concluded that both methods offered high performance in management of mandibular angle fractures. However, SSOP group had a significantly shorter operating time, increased bone density and less edema. Clinical trial registration number: NCT03839368.

The effect of bony cochlear nerve canal (BCNC) diameter on the degree of sensorineural hearing loss.

PURPOSE: This study investigated the correlation between the diameter of the bony cochlear nerve canal (BCNC), as determined by Temporal bone CT, and MRI findings of cochlear nerves (CN) in children with sensorineural hearing loss (SNHL). MATERIALS AND METHODS: A prospective study design was followed. Radiological data (Temporal bone CT and MRI) of fifty children with sensorineural hearing loss (age <18 y) were included in the study. All patients (100 ears) underwent routine MRI protocol in addition to 3D CISS (3-D constructive interference in steady state). RESULTS: Based on CT findings, the BCNC was classified according to its diameter into three groups; group 1 (<1.4 mm), group 2 (1.4-2.0 mm), and group 3 (>2.0 mm). A significant difference between the three groups at degrees of SNHL (p < 0.001) was observed. Significant difference (p < 0.001) was also observed in the mean level of pure tone audiometry (PTA) average in group 1 compared to group 2. The CN was absent in 20 ears of group 1 CT results (29%), CN hypoplasia was noticed in 40 ears of group 1 CT (58%). However, CN was present in 9 ears of group 1 CT (13%), while in group 2 and 3, CN was present in 100% of the cases (27, and 4 ears, respectively, p < 0.001). CONCLUSIONS: MRI and CT imaging are valuable in the diagnosis of SNHL in children. Moreover, with BCNC stenosis, there was a high probability of CN aplasia or hypoplasia.

Cartilage tympanoplasty in the treatment of adhesive otitis media with and without Eustachian tube balloon dilatation.

Purpose: To compare cartilage tympanoplasty (CT) combined with eustachian tube balloon dilatation (ETBD) and cartilage tympanoplasty alone as a surgical treatment modality for adhesive otitis media (AdOM) in terms of graft healing, audiological outcomes, and impact on life style, using Chronic Otitis Media Outcome Test 15 (COMOT-15). Methods: 50 patients with AdOM were randomly classified into 2 groups: 25 patients for cartilage tympanoplasty only (CT group) and 25 patients for cartilage tympanoplasty combined with eustachian tube balloon dilatation (CT + ETBD group). Clinical outcomes in both groups were compared at 3 and 6 months of follow up. Results: There was no significant difference in graft healing between the two groups. Postoperative COMOT-15 scores significantly decreased in both groups with a significant difference between the groups with regard to the decrease in COMOT-15 scores at 3 and 6 months of follow-up (P < 0.05). Hearing improvement was achieved, as the mean preoperative ABG was 26.5 ± 5.4 and 27.1 ± 4.6 dB, and the mean postoperative ABG at 6 months was 19.4 ± 4.4 and 14.6 ± 3.9 dB in the CT and the CT + ETBD groups, respectively. The difference in the magnitude of ABG reduction in the two groups was significant at 3 and 6 months of postoperative follow-up (P < 0.05) in favour of the CT + ETBD group. Conclusion: ETBD can increase the success rate of cartilage tympanoplasty in patients with AdOM by enhancing the audiological outcome and quality of life.

Correlation Between Nasal and Laryngeal Lesions of Rhinoscleroma in Patients of Upper Egypt.

INTRODUCTION: Rhinoscleroma (RS) is a chronic granulomatous disease of URT caused by Klebsiella Rinoescleromatis. RS is considered endemic in Egypt. The nasal mucosa represents the primary region of occurrence. The disease can potentially spread to involve the larynx and trachea causing dysphonia, stridor, and airway obstruction. OBJECTIVES: To describe various nasal and laryngeal presentations of RS in our endemic area, to correlate between these findings and to alert physicians to suspect RS in any case of unexplained nasal or laryngeal lesion. METHODS: The study included 100 patients admitted in our otorhinolaryngolgy department (Minia University, Minia, Egypt). Patients presented with various manifestations of Rhino-pharyngo-laryngo scleroma. Diagnosis based on clinical, bacteriological, and pathological examination. RESULTS: Patients had typical nasal stages of RS, however; only 12 % of patients had the typical described laryngeal presentations (ie, subglottic narrowing and subglottic membrane). Other patients presented with atypical laryngeal presentations (eg, unhealthy vocal folds, ventricular fold hypertrophy, and suproglottic sticky greenish discharge). There was significant correlation between nasal stages and laryngeal lesions. CONCLUSION: RS can present with atypical laryngeal presentations in endemic areas which should be kept in mind to avoid misdiagnosis. Possible laryngeal lesions of RS can be predicted from observing associated nasal lesions.

Ursodeoxycholic acid use is associated with significant risk of morbidity and mortality in infants with cholestasis: A strobe compliant study.

The off-label use of medications is a "right" for pediatricians, owing to lack of enough safety and effectiveness drug trials in pediatric age group. Pediatricians have to rely on their personal judicial use of medications in children.We studied off-label use of ursodeoxycholic acid (UDCA) retrospectively during 2005 to 2015 among those who attended the Pediatic Hepatology Unit, Cairo University.We analyzed data of 779 neonates and infants with cholestasis. 15% dropped out. Males comprised 374 (56.5%). Cholestasis was due to surgical causes in 129 (19.5%), neonatal hepatitis in 445 (67.2%), and paucity of intrahepatic bile ducts in 88 (13.3%). Three hundred sixty (54.4%) received UDCA (15-30 mg/kg/d), and 302 (45.6%) did not. Both groups were matched as regards causes and severity of cholestasis. Those who received UDCA had worse outcome (P < .001), and more complications (P < .001). A total of 73.1% (221) achieved cure without UDCA compared to only 45.8% (165) of those on UDCA (P < .001).UDCA is not effective and not safe in Egyptian neonates and infants with cholestasis. UDCA use compromises chance of cure, and is associated with serious morbidity, progression of disease, and death. UDCA off-label use mortality was absolutely preventable. Off- label use of UDCA in neonates and children should be utterly prohibited. Information of use of off-label medications, effectiveness, and safety, should be recorded, analyzed, and made available within context of Off-label Use Registry Studies with informed consent of parents.

Restenosis Predictors after Carotid Angioplasty and Stenting and Its Influence on Procedure Durability, Single-Center Experience.

BACKGROUND: This article reports our experience regarding in-stent restenosis in the carotid arteries with special focus was given to angiographic morphology and clinical predictors of in-stent restenosis. METHODS: Between July 2008 and August 2011, 245 carotid angioplasty and stenting procedures were performed in 243 patients (172 men and 71 women). Stenting for de novo stenoses was performed in 214 (87.3%) carotid arteries, and 31 (12.7%) vessels were treated because of postsurgical restenosis. Symptomatic lesions were detected in 187 patients (76.3%). Angiography confirmed any significant recurrent lesion detected on the ultrasound scan. Symptomatic or significant (70%) recurrent lesions detected on the ultrasound scan were an indication for retreatment. RESULTS: During the follow-up period of 821 days (range: 62-1750 days), there were 10 deaths, all non-procedure related. Stent restenosis was defined as greater than 30% narrowing of the vessel lumen diameter and could be detected in 35 (14.3%) patients. Retreatment was indicated in 16 (6.5%) patients. Three types of restenosis were differentiated: tandem type restenosis (n = 5 of 35); "in-stent" restenosis (n = 18 of 35); and "end-stent" restenosis (n = 12 of 35). Interventions, either dilation alone (n = 12) or dilation with restenting (n = 4) for restenosis, were performed with 1 procedure-related dysphasia that resolved in 30 days. Female gender, hypercholesterolemia, peripheral vascular disease (PVD), initial stenosis, and surgical graft were predictors of target lesion revascularization. CONCLUSIONS: In our cohort, history of surgical endarterectomy, female gender, hypercholesterolemia, PVD, and initial stenosis were predictors of in-stent restenosis. Three types of restenosis were identified in our cohort.
