Eplasty. 2020;20:e12 Authors: Kachare SD, Meredith LT, Kachare MD, Vivace BJ, Kapsalis CN, Muresan C, Choo JH, Kasdan ML, Wilhelmi BJ Abstract Introduction: Use of local anesthesia in awake patients undergoing hand surgery has become increasingly popular. A thorough understanding of local anatomy, such as the distal wrist for ulnar nerve block, is required to provide safe blockade. We sought to conduct an anatomic study of the distal wrist and review cadaveric studies describing various techniques for ulnar nerve block. Methods: Dissection of fresh-frozen cadaver forearms at the University of Louisville Robert Acland Fresh Tissue Lab assessing relationships between the flexor carpi ulnaris tendon and the ulnar nerve and the ulnar artery was performed. Three cadaveric studies on ulnar nerve blockade using the ulnar, volar, and/or transtendinous technique were identified and reviewed. Results: A total of 16 cadaver forearms of equal male to female ratio were obtained. The ulnar nerve was noted to be directly posterior to the flexor carpi ulnaris tendon in 15 (93.8%) forearms, with 1 (6.3%) specimen having the nerve ex tend along the ulnar border of the flexor carpi ulnaris. The ulnar artery was radial to the ulnar nerve 1 cm proximal to the pisiform in all specimens. In all 3 cadaveric studies, only the ulnar technique was associated with no ulnar artery and/or ulnar nerve injury. Conclusion: Knowledge of distal wrist anatomy can help minimize risk of iatrogenic injury during local blockade. On review, the ulnar approach provides the safest method for ulnar nerve block.

Μέσω pubmed: "eplasty"[jour] Related Articles Orbital Roof Blowout Fracture With an Intact Orbital Rim: A Case Report. Eplasty. 2020;20:e13 Authors: Hwang K, Oh SY Abstract Background: Fractures of the orbital roof not associated with fractures of the orbital rim are unusual. We describe the case of a blowout fracture of the orbital roof with an intact orbital rim, which was found after craniotomy for removal of epidural hematoma. Case: A 64-year-old man was referred to our emergency department from a local hospital. He fell down from a 3-m stepladder while pruning branches of a tree. Brain computed tomographic scan revealed acute epidural hematoma in both frontal convexities, and he underwent craniotomy at the local hospital. On follow-up brain computed tomography, an orbital roof fracture with a displaced bony fragment and hemorrhage was noticed in the left superior extraconal space. Thereafter, he was transferred to our department. Upon examination, movement of the extraocular muscles was normal. He did not complain of diplopia or decreased sensation of the face. He also did not have nasal stuffiness. Exophthalmometry revealed the same findin gs for both eyes (18 mm/18 mm). Facial computed tomographic scan before the second operation revealed a displaced orbital roof fracture segment. Under general anesthesia, craniotomy was performed and the epidural hematoma was evacuated. The displaced bony fragment was removed from the left anterior cranial fossa, and the anterior skull base was reconstructed with a titanium mesh plate. Conclusion: Through this case of blowout fracture of the orbital roof with an intact orbital rim, found after craniotomy, we should be aware of the possibility that an orbital roof fracture can be missed on conventional brain computed tomography.

Μέσω tinnitus Related Articles A Chart Review to Assess the Response of Veterans Suffering from Tinnitus to Alpha Burst Transcranial Magnetic Stimulation. Int Tinnitus J. 2020 Nov 18;24(1):40-48 Authors: Ring A, Crowder C, Wyer SL, Phillips B Abstract OBJECTIVE: The purpose of this chart review was to assess the response of veterans suffering from tinnitus to Magnetic EEG/EKGguided resonance therapy and Alpha Burst Stimulation (ABS), while also investigating the safety profile of this therapy combination. EEG/EKG-guided Repetitive Transcranial Magnetic Stimulation (rTMS) delivers high-energy electromagnetic pulses to induce current flow in the neocortex. ABS provides rTMS pulses in short, high-frequency bursts. MATERIALS AND METHODS: All equipment used to evaluate and treat participants are either FDA-cleared or are exempt from clearance and listed with the United States FDA. Stimulation was delivered with a MagPro R30 and an MCF-B65 butterfly coil. Charts were reviewed from patients who had received a combination of EEG/EKG-guided rTMS and ABS therapy to relieve symptoms of tinnitus. Paired samples t-tests were performed on the Tinnitus Functional Index (TFI) and Neurobehavioral Symptom Inventory (NSI) scales. Treatment logs and therapy notes were reviewed for safety data. Adverse events or side effects were extracted from therapy notes. Linear regression was used to analyze the relationship between number of therapy sessions, and reported patient symptoms. RESULTS: Eighteen of the 23 patients reported significant improvements in tinnitus symptoms. For patients reporting improvements, there was an average 44% reduction in tinnitus symptoms and a 60% reduction in NSI scores following intervention. No patients experienced adverse side effects. The most common side effects were headache and fatigue. CONCLUSION: Based on the results from this study, noninvasive neuromodulation holds promise as a potential treatment for tinnitus. Additional investigation in controlled studies may be warranted. PMID: 33206487 [PubMed - in process] View on the web Inoreader. Take back control of your news feed.

Μέσω tinnitus Related Articles Clinical and morphological results of xenografts to use in myringoplasty. Int Tinnitus J. 2020 Nov 18;24(1):1-6 Authors: Aj B, Khm M, Us K, Sh K, No A, Ja D, Az S, Se A Abstract The main aim of our study was to study morphological state of the autograft from the fascia of the temporal muscle in myringoplasty. Until now, there is no consensus on issue of which fabrics are more suitable for use in the eardrum. We decided to study of use of an autograft from the fascia of the temporal muscle for myringoplasty in rabbits in the experiment, and in patients with chronic dry mesotympanitis. An electron microscopic examination of the fascia taken immediately, after 10, 20 min and 1 h after sampling. It was found that there are no gross destructive changes in the fascia structure. Minor changes are detected in the form of a light disorganization of the collagen complex, granular dystrophy with an increase in cell. Inflammatory diseases of the middle ear are widespread among population of all age groups. In the experiment, a positive result was obtained in 29 (82.8%) rabbits. In our research we performed morphological features of xenograft engraftment in an ex perimental animal on 3, 7, 14, 21 days and 1-3 months. In period from 3 days to 3 months after operation, the animals were euthanized by an air embolism and subjected to pathological examination. Then recovered xenograft, was examined macro and microscopically. Pieces were fixed in a 10% solution of neutral formalin. After washing with water, dehydration was carried out in alcohol and chloroform, and after, waxed with paraffin. Histological sections were stained with hematoxylin-eosin. Collagen fibers were detected by method of Vann-Gieson. PMID: 33206488 [PubMed - in process] View on the web Inoreader. Take back control of your news feed. Follow us on Twitter and Facebook.

Μέσω tinnitus Related Articles Influence of Cochlear Implantation on Balance Function in Pediatrics. Int Tinnitus J. 2020 Nov 18;24(1):xxx-xx Authors: Bayat A, Farhadi M, Emamdjomeh H, Nadimi Z, Mirmomeni G, Saki N Abstract BACKGROUND AND OBJECTIVE: Patients with profound Sensorineural Hearing Loss (SNHL) are susceptible to vestibular disturbances following Cochlear Implant (CI) surgery. This study aimed to evaluate vestibular dysfunctions following unilateral CI in the congenitally deaf children. METHODS: This was a cross-sectional study conducted on 24 children (mean age: 10.56 ± 5.49 years old) who underwent unilateral CI and 24 age-matched controls (mean age: 11.13 ± 6.21 years old). Vestibular functions were assessed by Vestibular Evoked Myogenic Potential (VEMP) and Computerized Dynamic Posturography (CDP). The VEMP test was performed for otolith's function (especially saccule) evaluation. Sensory Organization Test (SOT) protocol of CDP was also utilized to differentiate the role of various sensory systems contributing to postural stability. In addition, total equilibrium score was calculated. The variables were comparatively assessed between the two groups. RESULTS: The mean p13-n23 amplitude in the CI users was significantly lower than the controls (p<0.05). However, the two groups showed no significant difference in cVEMP latency values (p>0.05). The SOT analysis revealed that 45.83% (11/24) of the CI subjects had some kind of sensory abnormalities: 7 cases (29.17%) vestibular, 2 cases (8.33%) visual, 2 cases (8.33%) vestibular and somatosensory involvements. Furthermore, total equilibrium score was significantly reduced in implanted group than the controls (p<0.001). At least, 70.59% (12/24) CI patients showed abnormal values in the CDP or cVEMP examinations. CONCLUSION: This study shows functional vestibular impairments in children who underwent CI. These patients showed significantly increased postural instability which was more evident in dynamic conditions. These findings provide the basis for better pre-operative counseling and postoperative vestibular rehabilitation to CI recipients. PMID: 33206489 [PubMed - in process] View on the web Inoreader.
