Comparison of Endoscopic Versus Microscopic Tympanoplasty: A Prospective Randomised Study.

Aim: To compare endoscopic versus microscopic method for tympanoplasty in terms of Graft uptake and hearing outcome. Material and methods: A randomized prospective observational study was done. 60 patients who came to ENT outpatient of tertiary care teaching hospital requiring operative intervention for inactive mucosal chronic otitis media. Randomization was done and patients divided into two groups with Group A undergoing endoscopic tympanoplasty and Group B undergoing microscopic tympanoplasty. Post operative graft uptake and hearing improvement were compared between both groups. Intraoperatively visualization of middle ear structures, surgeon's comfort, duration of surgery, post operative pain, giddiness was compared. in both the groups. Results: Total 60 patients got randomly divided in the two groups. There was no difference in terms post op graft success rate and post operative hearing improvement in both the groups Intra operative visualization of middle ear structures better in the endoscopic group and also the surgical time was significantly less in endoscopic group. Conclusion: On comparing endoscopic versus microscopic tympanoplasty in patients of mucosal chronic otitis media, success rate in terms of graft acceptance and hearing improvement was equal between both groups. However, visualisation of middle ear structures was better in endoscopic method. Operating time was shorter in endoscopic tympanoplasty.

[Endoscopic ear surgery -- Discipline establishment and technological innovation].

The application of microscope is a milestone in the history of otosurgery, which makes otologists deal with middle ear lesions more clearly and finely, and helps otologists expand the scope of treatment to the lateral skull base area, which greatly promotes the development of otosurgery. In the past 20 years, with the continuous improvement of endoscopic equipment research and development and the gradual improvement of endoscopic technology, the application of endoscopic technology in China has shown an explosive development, and Chinese otolaryngologists have experienced from the initial attempts of endoscopic technology, to the widespread popularization of innovative and applicable technology, and then to the feasibility of exploring the future innovative concepts. Endoscopic technology is another revolutionary push for the development of otosurgery after the microscope.

Endaural microscopic approach versus endoscopic transcanal approach in treatment of attic cholesteatomas.

PURPOSE: Compare the audiological results and postoperative outcomes of the endoscopic approach versus the endaural microscopic approach for treatment of attic cholesteatomas, using a randomized prospective model. MATERIALS AND METHODS: Eighty patients were consecutively enrolled in the study and randomized into two groups of treatment of 40 patients: Group A -tympanoplasty with a microscopic endaural approach; Group B -tympanoplasty with an exclusive trans-meatal endoscopic approach. Preoperative, intraoperative and postoperative outcomes were evaluated. Hearing was assessed preoperatively and at 1 month, 3 months and 6 months after surgery in both groups. RESULTS: There were no differences in the parameters analyzed (CT findings, patient age, disease duration, intraoperative cholesteatoma characteristics,) between the group A and B patients. No statistical difference between the two groups regarding hearing improvement, abnormal taste sensation, dizziness, post-operative pain and healing times emerged. Graft success rate was 94.5 % and 92.1 % for MES and ESS respectively. CONCLUSION: Both microscopic and exclusively endoscopic endaural approaches offer similar and excellent results in the surgical treatment of attic cholesteatomas.

Patient-Reported Postoperative Pain and Numbness: Applications for Endoscopic vs. Microscopic Ear Surgery.

Background: Transcanal endoscopic ear surgery (TEES) avoids a postauricular incision, which has been shown to minimize pain and numbness. Our objective is to assess how much patients value minimizing pain and numbness relative to other postoperative otologic outcomes. Methods: Cross-sectional anonymous surveys were distributed to otolaryngology clinic patients in a tertiary care center. Patients were instructed to rate how much they value various outcomes when undergoing hypothetical ear surgery on a scale of 0 (not important) to 10 (very important). Results: 102 patients responded. Ten percent of survey respondents were Spanish-speaking. Outcomes of the highest importance included hearing (mean 9.3; SD 1.9), staff friendliness (8.9; 1.8), numbness (8.3; 2.4), and pain (8.1; 2.5). Outcomes of moderate importance included time spent under anesthesia (7.0; 3.2), scar visibility (6.3; 3.5), incision size (5.5; 3.4), incision hidden in the ear canal (5.4, 3.9), and surgery cost to the hospital (5.1; 3.9). In linear regression analysis, increasing age was associated with decreased value placed on incision size (p < 0.001) and scar visibility (p < 0.001). Conclusion: Patients placed a high value on minimizing pain and numbness after ear surgery, nearly as much as a good hearing outcome. These patient-centric outcomes are important in justifying the minimally invasive approach of TEES.

Changing Scenario in Tympanoplasty: Endoscopic Versus Microscopic Approach.

Tympanoplasty is the most common surgery performed for Chronic Otitis Media. Here we have compared the minimally invasive endoscopic tympanoplasty with the conventional microscopic tympanoplasty. It's a comparative prospective study, involving cases of Chronic otitis media with dry perforation analysed from January 2009 to October 2019. Equally 312 patients were divided into two groups, 156 in each group and subjected for Endoscopic and Microscopic Tympanoplasty. Various parameters were studied. Graft success rate of 98.08% and 93.58% in group A and B respectively were comparable, hearing improvement in both groups was not statistically significant with p-value > 0.05, whereas the postoperative hearing improved significantly to preoperative in both groups. Endoscopic and Microscopic tympanoplasty has similar outcomes, in terms of graft success rate, hearing and duration of surgery. Cosmetic results were better in Endoscopic group whereas canalplasty rates were evident in Microscopic group.

Comparison of endoscopic and microscopic management of attic cholesteatoma: A randomized controlled trial.

BACKGROUND: Attic cholesteatoma is a common disease encountered by otologists. OBJECTIVES: To compare the endoscopic approach to attic cholesteatoma with conventional microscopic technique. MATERIAL AND METHODS: A total of 190 patients (192 ears) diagnosed with attic cholesteatoma extending to the antrum area (stages Ib and II) were randomly assigned into two groups undergoing endoscopic approach and the other microscopic technique. The outcomes were preoperative and intraoperative findings, access to hidden areas expressed in MESVI, mean operative time from first incision to ear-packing, and postoperative findings. Statistical analysis was performed by SPSS version 24.0, and P ≤ 0.05 was considered statistically significant. RESULTS: The median Middle Ear Structural Visibility Index of the endoscopic group was better than the microscopic group (P < 0.05). The mean operating time by the endoscopic approach was less than the microscopic approach (P < 0.05). The median postoperative pain score in the endoscopic group was lower than the microscopic group (P < 0.05). In addition, there were no statistically significant differences in taste, hearing, vertigo, healing time and long term outcomes between the two groups. CONCLUSION AND SIGNIFICANCE: Endoscopic management of limited attic cholesteatoma showed definite advantages over the conventional microscopic approach, such as providing better visualization, requiring less postoperative time, subjecting the patients to less pain, and decreasing the incidence of complications.

Educational Value of Endoscopic Versus Microscopic Ear Surgery.

OBJECTIVE: To compare the educational value of endoscopic ear surgery versus microscopic ear surgery among medical students. METHODS: Medical students anonymously completed a cross-sectional survey immediately after observing endoscopic or microscopic ear surgery. A Likert scale (1 = worst, 5 = best) was used to analyze variables across 3 domains including: (1) area of interest visibility, (2) optical quality, (3) education and understanding. The Mann-Whitney U-test and multivariable linear regression were used to compare mean scores of individual items and domain means between endoscopic and microscopic groups. RESULTS: Forty-four surveys were analyzed (20 endoscopic and 24 microscopic ear surgeries). Across domains, the endoscope was superior to the microscope (adjusted P < .05) for visibility of the area of interest (mean ± SD: 4.74 ± 0.26 vs 4.28 ± 0.50), optical quality (4.78 ± 0.38 vs 4.28 ± 0.64), and education and understanding (4.70 ± 0.47 vs 4.13 ± 0.61). In multivariable linear regression, the mean domain score for visibility of the area of interest was 1.23 (95% CI = 0.56, 1.90; adjusted P < .01) points higher for the endoscopic group, compared to the microscopic group, adjusting for surgeon, procedure, and student type. The mean domain score for education and understanding was 1.19 (95% CI = 0.49. 1.90; adjusted P < 0.01) points higher for the endoscopic group, compared to the microscopic group, adjusting for the same confounders. CONCLUSIONS: Among medical students, endoscopic ear surgery was superior to microscopic ear surgery for several visual quality indicators and perceived educational benefit. These findings have implications for medical student education and surgical training.

Current trends and applications in endoscopy for otology and neurotology.

There has been a rapid increase in endoscopic ear surgery for the management of middle ear and lateral skull base disease in children and adults over the last decade. In this review paper, we discuss the current trends and applications of the endoscope in the field of otology and neurotology. Advantages of the endoscope include excellent ergonomics, compatibility with pediatric anatomy, and improved access to the middle ear through the external auditory canal. Transcanal endoscopic ear surgery has demonstrated comparable outcomes in the management of cholesteatoma, tympanic membrane perforations, and otosclerosis as compared to microscopic approaches, while utilizing less invasive surgical corridors and reducing the need for postauricular incisions. When a postauricular approach is required, the endoscopic-assisted transmastoid approach can avoid a canal wall down mastoidectomy in cases of cholesteatoma. The endoscope also has utility in treatment of superior canal dehiscence and various skull base lesions including glomus tumors, meningiomas, and vestibular schwannomas. Outside of the operating room, the endoscope can be used during examination of the outer and middle ear and for debridement of complex mastoid cavities. For these reasons, the endoscope is currently poised to transform the field of otology and neurotology.

Comparative Study of Endoscopic and Microscopic Type I Tympanoplasty in Terms of Delayed Facial Palsy.

OBJECTIVE: Delayed facial palsy is a complication of otologic surgery. Tympanoplasty is commonly employed in chronic otitis media. We compared the incidence and characteristics of delayed facial palsy and hearing restoration between endoscopic and microscopic tympanoplasty for the treatment of simple chronic otitis media. STUDY DESIGN: Retrospective cohort study. SETTING: Tertiary medical center. SUBJECTS AND METHODS: We retrospectively analyzed 468 patients who underwent type I tympanoplasty from January 2009 to April 2017. Patients were divided into transcanal endoscopic ear surgery and microscopic ear surgery groups. Their epidemiological profiles were reviewed and the outcomes of tympanoplasty were analyzed. Blood sample tests for herpes simplex virus and varicella-zoster virus immunoglobulin M and immunoglobulin G were arranged in patients with delayed facial palsy. RESULTS: Transcanal endoscopic ear surgery exhibited similar benefits to microscopic ear surgery in graft-taking rate and hearing restoration but had a shorter operation time (P < .01). Eight patients (1.71%) developed delayed facial palsy, but no statistically significant difference was observed between the 2 surgical approaches. All patients tested negative for varicella-zoster virus and herpes simplex virus immunoglobulin M and positive for immunoglobulin G of the same viruses; however, the titer did not exhibit a 4-fold increase, implying that patients did not have active viral infections. CONCLUSION: Transcanal endoscopic ear surgery is an ideal alternative for simple tympanoplasty. The incidence of delayed facial palsy was not significantly different between the 2 approaches. Because of the favorable prognosis and the absence of direct serological evidence supporting viral reactivation, treatment with antivirals may not be required.

Assessment of Pain and Analgesic Use in Children Following Otologic Surgery.

OBJECTIVE: To compare postoperative pain and analgesic use in children following transcanal endoscopic ear surgery (TEES) vs non-transcanal endoscopic ear surgery (non-TEES). STUDY DESIGN: Prospective case series. SETTING: Tertiary care center. METHODS: Surveys using the Wong-Baker FACES Pain Rating Scale and recording the frequency and dosage of consumed analgesics were administered prospectively to caregivers of children undergoing otologic surgery between May 2018 to February 2020. Pain intensity and medication use were recorded twice daily for 6 days, starting on postoperative day 0. Mean pain scores and mean number of consumed analgesic doses were compared between groups. RESULTS: Survey response rate was 57.9%. Among 53 patients who completed the survey, 35 (66.0%) underwent TEES and 18 (34.0%) underwent non-TEES. Mean pain ratings on postoperative days 0 and 1 were significantly lower among children undergoing TEES (2.2 and 2.1) vs non-TEES (4.0 and 4.1), P = .045 and P = .008, respectively (Mann-Whitney U test). The mean pain ratings across the 6 days were similar in TEES (1.7) and non-TEES (2.6) (P = .140, Mann-Whitney U test). The mean number of analgesic doses consumed per half-day over the 6 days was significantly lower among children undergoing TEES (0.3) vs non-TEES (0.6; P = .049, Mann-Whitney U test). CONCLUSION: Postoperative pain following TEES and non-TEES in children was overall low. Children undergoing TEES had a small but statistically significant decrease in pain on postoperative days 0 and 1 and decreased use of pain medications compared to non-TEES.

Fully endoscopic laser stapedotomy: is it comparable with microscopic surgery?

BACKGROUND: Microscopic stapedotomy is very successful and has long history, but it still has some constraints. Thus, otoendoscopy is increasingly popular nowadays. AIMS/OBJECTIVES: The retrospective review study was to investigate the role of endoscopic laser stapedotomy in treating patients with otosclerosis. MATERIALS AND METHODS: Seventeen patients who received endoscopic laser stapedotomy from April 2014 to July 2017 were enrolled and compared to 13 patients who had microscopic stapedotomy from February 2009 to March 2012. The anatomical structures, operative time, and postoperative hearing outcomes were assessed in two groups. Relation between external acoustic canal and operative time was also analyzed. RESULTS: Using an endoscope, the operative field was clear, with easily identified anatomy, without need to sacrifice bony structures. The operative time was significantly longer in the endoscopic group in 2014 and decreased in the following years. There was no significant difference of hearing improvements between the two groups. There was a weak correlation between the width of the external auditory canal and the operative time. CONCLUSIONS AND SIGNIFICANCE: Fully endoscopic stapes surgery is a feasible and safe surgical technique and results in satisfactory hearing outcomes. However, surgeons take longer to master the technique and to achieve shorter endoscopic operative times.
