“…Hearing results were not reported in 4 papers. 9,10,13,19 Hearing thresholds were reported using either pure tone audiogram results, bone conduction thresholds only, or distorted product otoacoustic emission (for children). Because of the heterogeneous way of reporting hearing outcomes, it was not possible to compare hearing outcomes in different groups.…”

“…These studies were published between 1997 and 2020 and conducted in America, Asia, and Europe. Four of them were case reports, [8][9][10][11] 5 were retrospective cohort studies, [12][13][14][15][16] and 3 were prospective cohort studies. [17][18][19] Recruited participant numbers ranged from 2 8,11 to 200.…”

“…As part of their outcome measure, 9 papers 10,11,[13][14][15][16][17][18][19] looked at the presence or absence of residual disease at either a second stage operation, with diffusion-weighted magnetic resonance imaging or computed tomography scan at least 12 months after the first operation or clinical observation. There were 2 papers that had a control group and compared the outcomes of laser versus no laser, while Hamilton in 2005 17 showed that using a laser significantly reduced the chance of residual disease after 12 months, Sharma et al in 2020 19 did not report any significant difference between using the laser or not.…”

Lasers in Cholesteatoma Surgery: A Systematic Review

et al. 2020

Objectives: The mainstay of cholesteatoma treatment is surgical and requires the removal of all squamous epithelium from the underlying normal structure. The application of laser technology in middle ear and mastoid surgery has shown promise in achieving both disease eradication and hearing preservation. This systematic review aims to include studies that have assessed the application of laser to the treatment of cholesteatoma and to review its outcomes in terms of disease eradication as well as hearing results. Method: Two independent researchers conducted a systematic review of the literature on MEDLINE and Cochrane library, according to PRISMA guidance. Result: The search resulted in 12 papers, reporting on 536 participants that fulfilled the inclusion criteria. The hearing results did not show that using laser surgery improved hearing in cholesteatoma surgery, but neither has the use of laser shown to deteriorate hearing. With regards to the prevention of residual/recurrent cholesteatoma, the current literature reports a residual/recurrent rate of 0% to 33%. The complication rate of facial palsy is 0.6%. Conclusion: While there is certainly a role for future studies especially randomised large-cohort prospective comparative studies, the current literature suggests that laser may have a role in prevention or minimizing of residual cholesteatoma and generally have a safe hearing outcome profile.

“…The number of subjects collected for meta‐analysis was 1004, including 513 patients belonging to EES and 491 patients under MES, and the included studies were published between 2015 and 2017. Nineteen studies were analyzed qualitatively, which were all case series studies, except for one retrospective cohort study (Table ) . The included studies were published between 1995 and 2017, and a total of 406 patients were evaluated.…”

Comparison of endoscopic and microscopic ear surgery in pediatric patients: A meta‐analysis

et al. 2018

Objectives Recently, the endoscope has been increasingly introduced for middle‐ear surgery. To evaluate the postoperative outcomes of endoscopic ear surgery (EES) in pediatric patients, we did a qualitative analysis with a systematic review and quantitative analysis with meta‐analysis of available literature. Methods Studies reporting the comparative surgical outcomes of EES in pediatric patients were systematically reviewed by searching the MEDLINE, PubMed, and Embase databases from database inception through 2017. The selected articles included clinical studies conducted with at least 30 subjects and at least one postoperative parameter, including residual or recurrent cholesteatoma and graft success in tympanoplasty. Two investigators independently reviewed all studies and extracted the data using a standardized form. A meta‐analysis was performed using a random‐effects model and qualitative review was performed on the smaller studies. Results Ten studies were identified as appropriate for quantitative meta‐analysis and 19 studies for qualitative analysis. In the meta‐analysis, residual or recurrence rate of cholesteatoma was significantly lower in the EES group than in the microscopic ear surgery (MES) group (odds ratio [OR]: 0.56, 95% confidence interval [CI]: 0.38‐0.84, P = .005). The graft success rate of tympanoplasty was not statistically different between EES and MES groups (OR: 0.72, 95% CI: 0.41‐1.26, P = .249). In the qualitative analysis, most of the studies reported similar audiological outcomes after tympanoplasty and success rate of cholesteatoma removal between the two groups. Conclusions It appears that EES reduces the risk of residual cholesteatoma in children and that the success of perforation closure is equivalent to MES. Laryngoscope, 129:1444–1452, 2019

Open partial horizontal laryngectomy using CO₂ fiber laser

Background The application of CO2 fiber laser technology to ENT surgery has led to new interesting scenarios, both in endoscopic and in open surgical approaches. Methods The current video shows three examples of open partial horizontal laryngectomies (OPHLs) performed using CO2 fiber laser for resection procedures. Results CO2 fiber laser helped the surgeon in improving the accuracy of resection and the quality of surgical margins on specimen. The low thermal damage on tissues resulted in minor postoperative edema and a fast recovery of laryngeal function. Conclusions In our experience, the application of CO2 fiber laser showed some very useful features for performing OPHLs: a high cutting precision with very low tissue damage, the possibility of delivering energy without touching the organ, a modulable power for the various surgical steps, a very good maneuverability of the fine fiber holder during the procedure allowing the surgeon to “draw” the resection with a great accuracy.
