Conclusions: Microscopic technique can be used to enhance the quality and accuracy of strabisumus surgery and to reduce surgical damage, postoperativ inflammatory reaction and scar formation. All kinds of strabismus surgery, especially, oblique muscles and complex paralytic operations can be performed under microscope. Objective: To improve the quality of strabismus surgery and to find out the role of Microsurgery in the field of strabismus. Methods: We performed separation and preservation of anterior ciliary vessels(ACV), Adjustable sutures, routine rectus recession, and oblique muscle surgeries under Microscope in 13 cases of comitant strabismus, 19 cases of A-V syndrome and 8 cases of Paralytic strabismus.

A better understanding of endodontic disease and the causes of treatment failure hasrefined the role of surgery in endodontics. The advent of newer materials, advances insurgical armamentarium and techniques have also led to an improved endodonticsurgical outcome.Endodontic surgery straddles the specialties of endodontics and dento alveolar surgery. With the advent of the operating microscope, newer endodontic filling materials and stem cell therapy, humungous strides have been taken in this area, thus enabling transmutation of peri apical surgery into an avant-garde treatment modality.

Abstract Purpose Although latency has been cited as a disadvantage of the three-dimensional heads-up display (3D HUD) visualization system for vitreoretinal surgery, there have been no publications evaluating the effect of latency on surgical performance.Methods Thirty participants conducted two tasks (external suturing and inner limiting membrane peeling) on a 3D HUD at 4 levels of latency: 50?ms (ms), 68?ms, 92?ms, and 122?ms. The task completion time was measured and patients answered a subjective questionnaire on usability.Results No difference in completion times was found between different levels of latencies in either task. Regarding usability, significant decreases were found at 122?ms for both the suturing and peeling task overall, but for experienced HUD users, there was less of a decrease.Conclusion This study is the first to evaluate the effect of latency on 3D HUD for vitreoretinal surgery. The levels of latency in the current models of 3D HUD are unlikely to contribute to a decrease in surgical performance and usability with current technologies which have a latency of 70?ms.

Purpose Systematic review and meta-analysis comparing endoscopic and microscopic transsphenoidal surgery for Cushing’s disease regarding surgical outcomes (remission, recurrence, and mortality) and complication rates. To stratify the results by tumor size. Methods Nine electronic databases were searched in February 2017 to identify potentially relevant articles. Cohort studies assessing surgical outcomes or complication rates after endoscopic or microscopic transsphenoidal surgery for Cushing’s disease were eligible. Pooled proportions were reported including 95% confidence intervals. Results We included 97 articles with 6695 patients in total (5711 microscopically and 984 endoscopically operated). Overall, remission was achieved in 5177 patients (80%), with no clear difference between both techniques. Recurrence was around 10% and short term mortality 收起

Objectives Among the transsphenoidal (TSS) approaches to pituitary tumors, the microscopic approach (MA) has historically been the predominant technique with the increasing adoption of the endoscopic approach (EA). This study investigates national trends in TSS approaches and postoperative outcomes for MA and EA through 2021. Methods The TriNetX database was queried for patients undergoing TSS (MA and EA) between 2010 and 2021. Data were collected on demographics, geographic distribution of surgical centers, postoperative complications, stereotactic radiosurgery (SRT), repeat surgery, and postoperative emergency department (ED) visits. Results 8644 TSS cases were queried between 2010 and 2021. MA rates were highest until 2013 when rates of EA (52%) surpassed MA (48%) and continued to increase through 2021 (81%). From 2010 to 2015 EA had higher odds of a postoperative CSF leak (OR 3.40) and diabetes insipidus (DI (OR 2.30)) versus MA (p?收起

? 2022Background and aim: Colloid cysts are uncommon benign lesions. There is a lack of consensus regarding the preferred surgical strategy for colloid cyst resection; the technique with the optimal rates of remission, recurrence, mortality, and complications is debatable. Materials and methods: To determine surgical outcomes, we performed a systematic review of the published literature on Colloid cysts. Eligible studies (n = 63) with a prospective or retrospective evaluation of endoscopic or microscopic resection of third ventricle colloid cysts were included, which contained data describing extents of resection, seizures, meningitis, and tumor recurrence. A total of 3143 patients (1741 microscopically and 1402 endoscopically operated) were included in the final analysis. Results: According to the results of the meta-analysis, there was a higher rate of gross total resection (GTR) (98.15% versus 91.29%, p = 0.00), need for shunting (4.75% versus 1.46%, p = 0.04), postoperative complications (20.68% versus 10.42%, P = 0.03), mean operating time (194.18 versus 113.04 min), and duration of hospitalization (7.85 versus 4.69 days) for microscopic resection compared with endoscopic resection. While endoscopic resection is associated with a higher rate of cyst recurrence (1.78% versus 0.00%, P = 0.00), there was no difference in reoperation rate (0.49% for endoscopic versus 0.09% for microscopic resection). Conclusion: Microsurgical resection of third ventricle colloid cysts was associated with a higher rate of GTR and a lower rate of recurrence, while there was a lower rate of postoperative complications, duration of surgery, and shorter hospitalization period in the endoscopic group.

Introduction The role of endoscopes in the ear, nose, and throat (ENT) field has been described since the 1980s; It started with endoscopic nasal surgeries, followed by otological and laryngological procedures, and, since then, it has experienced a rapid evolution. Endoscopes help otologists understand how to approach difficult areas of middle ear, as well as the physiology of middle ear cleft. Objectives Despite the introduction of endoscopes in the field of otology, microscopes are still widely used in clinics and in operation theaters either alone or with endoscopes. The present study, which was conducted amongst otologists in India, is on their experience with and knowledge of the use of the endoscope compared to microscopes. Methods A Google form-based questionnaire comprising 18 questions was developed and sent online to otologist all over the country. The final dataset included responses from 354 active otologists. Results Out of 354 participants, only 3% had more than 5 years of experience in endoscopic ear surgery (EES), and 16.1% had never worked with an endoscope. Endoscopes were used in clinics and in operation theaters by 74.9% of the participants. Conclusion There has been a rise in the acceptance and use of endoscopes among Indian otologists and otology surgeons in last few decades.

BackgroundSeptal perforations consist in an anatomic defect of the mucosal, cartilaginous and/or bone tissues of the nasal septum. A huge variety of approaches and techniques for nasal perforation repair have been reported.Methodology/principalBetween January 2008 and January 2017, 38 patients were treated for nasal septal perforation in Department of Otorhinolaryngology Head and Neck Surgery, Fundacion Jimenez Diaz University Hospital, Madrid, Spain. A novel approach is presented based on microscope. Septal perforation closure was performed with endonasal bilateral advancement flaps-established technique and autologous cartilage and muscle temporal fascia grafts. We performed a retrospective review of closure rates and complications.ResultsA postoperative follow-up of at least 12months was performed in 37 patients. The mean size of perforation was 1.33cm. After the withdrawal of the silicone splints, perforations were completely closed in all cases. However, during the follow-up, four patients resulted in a reperforation, so our closure rate was 89.19%. For all cases, symptoms related to septal defect were solved. Only one case was reported of local infections that was resolved with antibiotics in a few days.ConclusionsMicroscopic approach of septal perforation closure using bilateral advancement flaps can be an affordable technique with a high percent of success and low rate of complications.
