Myringoplasty - A Rewiev of 438 Cases.

The medical records of 438 patients who underwent myringoplasty followed up for a minimum of one year in the period of 1980 and 2015 were revised. Examination under otomicroscope was done of the ear to be operated. This was carried out with a speculum under the operating microscope to be reliably asses the tympanic membrane, site of perforation, to rule out any other pathology and assess the status of ossicular chain. All the patients submitted primary myringoplasty surgery were operated under postauricular, endaural and transcanal approach with overlay, underlay and inlay methods. In the study the patients were divided into three groups depending upon the technique utilized to repair the tympanic membrane. When we compared overlay technique group with underlay technique group, it was observed that overlay technique was no statistically significant difference between these three groups in term of age wise distribution, gender wise distribution, duration of disease and cause of disease, due to matching at the time of selection. In this study the outcome in terms of graft uptake rate was slight better in the overlay technique (94%) as compared to the underlay technique (86.2%), though the difference was statistically insignificant, P>0.05. Patients selection may have had a role in the high success rate in the present study as patients presenting with middle ear pathology were excluded. The complications rate in the present study was quite low, no case in inlay group, three cases of graft lateralization in underlay group, and 19 cases in overlay group. In this study, better results were achieved with overlay technique may probably be due to less surgical manipulation and faster healing process.

[Advances in research on treatment of tympanosclerosis].

Tympanosclerosis is the hyaline degeneration and calcium deposition of the lamina propria of tympanic membrane and the submucosa of middle ear under long-term chronic inflammatory stimulation. At present, treatment primarily involves the surgical removal of sclerotic foci and reconstruction of auditory ossicular chain. However, excision of sclerotic lesions near critical structures like the facial nerve canal and vestibular window may result in complications like facial paralysis, vertigo, and sensorineural hearing loss. Developing safer and more effective treatments for tympanosclerosis has become an international research focus. Recent years have seen novel explorations in the treatment of tympanosclerosis. Therefore, this article reviews the latest advancements in research on the treatment of tympanosclerosis.

[Application and efficacy analysis of tympanic cartilage shaping device in endoscopic type â tympanoplasty].

Objective:To study the feasibility and efficacy of using a tympanic cartilage shaping device in endoscopic type Ⅰ tympanoplasty. Methods:A tympanic cartilage shaper was designed and manufactured by measuring tympanic membrane dimensions with HRCT imaging for cutting and shaping cartilage to repair the tympanic membrane. From August 2019 to October 2021, 66 patients（72 ears） with chronic suppurative otitis media in Xiangya Hospital underwent endoscopic type Ⅰ tympanoplasty with this tympanic cartilage shaping device, and were observed the tympanic membrane healing and hearing recovery effect after surgery. Postoperative follow-up ranged from 3-24 months, with an average of 9 months. The data were analyzed by the SPSS 26.0 software. Results:According to the imaging measurements, tympanic pars tensa width（8.60±0.20） mm, height（8.64±0.19） mm, design and manufacture a cylindrical cartilage shaping device with inner diameter 8.60 mm. After tympanoplasty, the healing rate of tympanic membrane was 100%; The average air-bone gap before surgery was（23.10±7.33） dB, then（14.30±6.40） dB 1 month after surgery, which were significant reduced compared with those before surgery. The average air-bone gap was（14.30±6.40） dB 3 month after surgery compared with 1 month after surgery, the difference was also statistically significant（t=6.630, P<0.05）. Conclusion:The tympanic membrane cartilage shaper shaping cartilage in endoscopic tympanoplasty is simple, stable and reliable, which can reduce the time of graft cartilage processing, improve the efficiency of surgery, and restore the tympanic membrane morphology and function in the postoperative period.

Registration of preoperative temporal bone CT-scan to otoendoscopic video for augmented-reality based on convolutional neural networks.

PURPOSE: Patient-to-image registration is a preliminary step required in surgical navigation based on preoperative images. Human intervention and fiducial markers hamper this task as they are time-consuming and introduce potential errors. We aimed to develop a fully automatic 2D registration system for augmented reality in ear surgery. METHODS: CT-scans and corresponding oto-endoscopic videos were collected from 41 patients (58 ears) undergoing ear examination (vestibular schwannoma before surgery, profound hearing loss requiring cochlear implant, suspicion of perilymphatic fistula, contralateral ears in cases of unilateral chronic otitis media). Two to four images were selected from each case. For the training phase, data from patients (75% of the dataset) and 11 cadaveric specimens were used. Tympanic membranes and malleus handles were contoured on both video images and CT-scans by expert surgeons. The algorithm used a U-Net network for detecting the contours of the tympanic membrane and the malleus on both preoperative CT-scans and endoscopic video frames. Then, contours were processed and registered through an iterative closest point algorithm. Validation was performed on 4 cases and testing on 6 cases. Registration error was measured by overlaying both images and measuring the average and Hausdorff distances. RESULTS: The proposed registration method yielded a precision compatible with ear surgery with a 2D mean overlay error of 0.65 ± 0.60 mm for the incus and 0.48 ± 0.32 mm for the round window. The average Hausdorff distance for these 2 targets was 0.98 ± 0.60 mm and 0.78 ± 0.34 mm respectively. An outlier case with higher errors (2.3 mm and 1.5 mm average Hausdorff distance for incus and round window respectively) was observed in relation to a high discrepancy between the projection angle of the reconstructed CT-scan and the video image. The maximum duration for the overall process was 18 s. CONCLUSIONS: A fully automatic 2D registration method based on a convolutional neural network and applied to ear surgery was developed. The method did not rely on any external fiducial markers nor human intervention for landmark recognition. The method was fast and its precision was compatible with ear surgery.

Endoscopic ossiculoplasty in traumatic conductive hearing loss with intact tympanic membrane: a five-year experience.

BACKGROUND: Exploratory tympanotomy in cases of traumatic ossicular disruption with intact tympanic membrane is crucial for both diagnostic and therapeutic purposes. Performing this procedure using the endoscope is gaining popularity. Hence, this study aimed to demonstrate varieties of ossicular pathology and their management in our institution. METHODS: A retrospective evaluation was conducted of 136 ears in patients with traumatic ossicular disruption with an intact tympanic membrane, who underwent endoscopic exploratory tympanotomy. A proposed algorithm was followed, to incorporate different traumatic ossicular possibilities. Assessment of hearing outcomes and surgical complications was performed six months post-operatively. RESULTS: Incudostapedial dislocation was the most commonly encountered type of traumatic ossicular disruption (35.3 per cent). Air conduction threshold improved significantly following endoscopic ossiculoplasty, from 50.9 ± 6.35 dB pre-operatively to 22.35 ± 3.27 dB post-operatively, with successful air-bone gap closure. CONCLUSION: Endoscopic ear surgery is effective in the diagnosis and management of challenging cases of post-traumatic ossicular disruption with an intact tympanic membrane.

Elective Tympanostomy Tube Removal at 2.5 Years: Results of a Protocol for Retained Tubes.

OBJECTIVES: In 2001, we instituted a protocol for the removal of retained tympanostomy tubes, delaying elective removal until 2.5 years after placement. It was hoped that this would decrease the number of surgeries without increasing the rate of permanent tympanic perforations compared to removal at 2 years. METHODS: Protocol: Fluoroplastic Armstrong beveled grommet tympanostomy tubes were placed by a single surgeon supervising the residents. The children were seen at 6-month intervals after placement. Children with a retained tympanostomy tube(s) at 2 years were seen again at 2.5 years, and the retained tubes were removed under general anesthesia with patch application. All were evaluated 4 weeks after surgery by otoscopy, otomicroscopy, behavioral audiometry, and tympanometry. STUDY: A computerized collection of patient letters and operative reports was queried to identify children treated according to the protocol between 2001 and 2022. Those with examinations at 2 years ± 1 month and 2.5 years ± 1 month and complete follow-up were included. RESULTS: Of the 3552 children with tympanostomy tubes, 497 (14%) underwent tube removal. One-hundred and forty seven children fit the strict inclusion criteria. Among those with retained tubes at 2 years, 67/147 (46%) had lost any remaining tube or tubes at 2.5 years and did not need surgery, 80/147 (54%) required unilateral or bilateral tube removal, 9/147 (6%) had a persistent perforation at 1-year follow-up, and 4/147 children (3%) required tympanic re-intubation after either spontaneous extrusion or removal and patching at 2.5 years. CONCLUSIONS: Delaying tympanostomy tube removal until 2.5 years can cut the need for surgery in half with, an acceptable (6%) incidence of persistent perforations. LEVEL OF EVIDENCE: Four case series-historical control Laryngoscope, 134:439-442, 2024.

Comparison of subcutaneous soft tissue versus temporalis fascia as a tympanoplasty graft material: a retrospective cohort study.

OBJECTIVE: This research compares the efficacy of subcutaneous soft tissue and temporalis fascia in tympanic membrane grafting for large tympanic membrane perforations. METHODS: A retrospective cohort study compared tympanic membrane graft success rate and hearing outcomes in 248 patients who underwent tympanoplasty using subcutaneous soft tissue (n = 118) or temporalis fascia (n = 130) via the post-auricular approach. RESULTS: Comparable results were observed in both groups. Tympanic membrane graft success rate was 98.3 per cent (116 ears) in the subcutaneous soft tissue group and 98.5 per cent (128 ears) in the temporalis fascia group. The rate of air-bone gap closure within 20 dB was 54.2 per cent (64 ears) and 60.0 per cent (78 ears) in the soft tissue and temporalis fascia groups, respectively (p = 0.360). CONCLUSION: Subcutaneous soft tissue is a reliable and readily available tympanic membrane graft material in both revision and primary tympanoplasty for large tympanic membrane perforations.

Outcomes of perichondrium graft covering the epithelium of the tympanic membrane for large-sized perforations: A 3-5-year follow-up study.

OBJECTIVE: The objective of this study was to evaluate the graft outcomes and iatrogenic cholesteatomas for 3 years following cartilage-perichondrium over-underlay technique with perichondrial graft covering the epithelium for large-sized tympanic membrane (TM) perforations. MATERIALS AND METHODS: This prospective case series enrolled patients with large-sized perforation who underwent endoscopic cartilage-perichondrium over-underlay technique. The graft success rate, hearing outcomes, and development of iatrogenic middle ear cholesteatomas and graft cholesteatomas were assessed at 3 years postoperatively. RESULTS: This study included 62 ears of 62 patients. The mean follow-up duration was 47.3 ± 10.8 (38-64) months. Neovascularization was observed in the lateral perichondrium graft in 55 (88.7 %) patients, which inosculated into the TM remnant at 4-5 weeks. However, graft neovascularization was not observed in the four patients with excessive perichondrium graft that migrated into the external auditory canal and the three patients with middle ear infections. The graft failure rate was 6.5 % at 6 months, 11.3 % at 12 months, 6.5 % at 24 months, and the overall graft success rate was 91.8 % at the last follow-up. Granular myringitis developed in 11.3 % (7/62) of the patients. High-resolution computed tomography revealed well-pneumatized mastoids and middle ear at the final follow-up. However, graft cholesteatomas were observed in 3 (4.8 %) patients at 7-24 months postoperatively. CONCLUSIONS: The cartilage-perichondrium over-underlay technique with perichondrial graft covering TM epithelium is safe and effective for the repair of large perforations, with good short- and long-term graft outcomes, minimal risk of graft cholesteatoma development, and no risk of iatrogenic middle ear cholesteatomas.

Foreign Body Reaction Requiring Re-Exploration After Tympanoplasty With Porcine Small Intestinal Submucosa Reconstruction.

OBJECTIVE: We present the first published case of large foreign body reaction to Biodesign (Cook Medical, Bloomington, IN), an acellular otologic graft matrix derived from porcine small intestinal submucosa, after use in tympanoplasty surgery in a patient without previous exposure to meat products. METHODS: A single case report of a 39-year-old female who developed tinnitus, ear drainage, and large fibrotic mass in external auditory canal and extending into middle ear after Type I medial graft tympanoplasty with Biodesign Graft. Left endoscopic microdissection and resection of the tympanic membrane and middle ear fibrotic mass were performed. MAIN FINDINGS: Surgical excision of the fibrous mass required extensive microdissection to ensure preservation of the ossicles and chorda tympani. Postoperatively, hearing improved and otalgia and otorrhea resolved. CONCLUSIONS: We report the first case of post-tympanoplasty reaction with the use of Biodesign acellular porcine graft in a patient with no previous known exposure to meat products. Although this presentation appears to be rare, it reinforces the need for careful patient selection and counseling around the use of porcine or other foreign grafts.

Diagnosis and management of bilateral lipoma of the middle ear.

INTRODUCTION: Middle ear lipomas are rare, accounting for less than 1% of all middle ear tumours. To our knowledge there have been only 16 reported patients with middle ear lipoma. Only one of these had bilateral congenital middle ear lipomas. The aim of this review is to comprehensive overview the diagnosis and management of congenital lipomas of the middle ear. METHODS: A literature review was performed searching multiple data bases, using the key words "middle ear", AND "lipoma", AND "congenital". A total of 116 articles were identified. One hundred were excluded on various criteria, leaving 16 articles for detailed review. Additionally, we report the second case of bilateral congenital middle ear lipoma. RESULTS: Based on this case report and literature review, the incidence of middle ear lipomas is greater in paediatric patients than in adult patients. Middle ear lipomas are distributed evenly between males and females. Three patients had recognised genetic syndromes, while five had prior ventilation tube placement. Clinically patients present with conductive hearing loss and middle ear effusions. In some cases, presence of a white or yellow mass behind the anterior aspect of the tympanic membrane is recognised. The most common location of the masses is in the anterosuperior quadrant of the middle ear, the site of predilection for small congenital cholesteatomas. An MRI scan is most useful in distinguishing between lipoma and cholesteatoma. All cases reported surgical excision of the middle ear lipoma. There was no evidence of recurrence noted up to 4 years follow up. CONCLUSION: Though rare, congenital lipomas of the middle ear should be a differential diagnosis of a middle ear masses. Early identification can allow surgical lipoma resection with minimal disruption to the ossicular chain. Though there is currently no consensus regarding management, surgical removal and appropriate reconstruction of the ossicular chain if needed, is appropriate.

Impact of palatoplasty techniques on tympanic membrane findings and hearing prognosis in children with cleft palate.

OBJECTIVE: Children with cleft palate (CP) are at high risk of developing otitis media with effusion (OME) due to Eustachian tube (ET) dysfunction. Palatoplasty has been reported to decrease the frequency of middle ear disease and improve ET function, and although various techniques have been developed, there is no consensus on the differences in the impact of different techniques on the middle ear. The purpose of this study was to determine the differential effects of palatoplasty on middle ear function and hearing. METHODS: We performed a retrospective observational survey of pediatric patients who underwent palatoplasty for CP between June 2010 and October 2018 at Tohoku University Hospital. Cases were divided into three groups depending on the palatoplasty procedures performed: the push-back palatoplasty group, the two-flap palatoplasty group, and the Furlow double-opposing Z-plasty group. We examined the differences in clinical characteristics between patients who underwent each procedure. The primary outcome variable was tympanic membrane (TM) findings, and the secondary outcome was hearing test results. RESULTS: Children who underwent the two-flap palatoplasty had a higher tympanostomy tube (TT) insertion rate and a higher total number of TT insertions than those who underwent the Furlow double-opposing Z-plasty or the push-back palatoplasty. The TM retraction rate tended to be lower in the Furlow double-opposing Z-plasty group than in the push-back palatoplasty group or the two-flap palatoplasty group. The hearing test results at the last visit were not significantly different among the three groups. CONCLUSIONS: Children who underwent the two-flap palatoplasty had a higher rate of TT insertions, potentially increasing the risk of TM perforation. In contrast, the Furlow double-opposing Z-plasty group had a lower tendency for TM regression, possibly due to improved ET function and reduced incidence of OME. It is important to understand the advantages and disadvantages of each technique before selecting one suitable for the child's cleft and arch width. Additionally, it is important to conduct regular follow-up of TM findings and hearing test results even after palatoplasty.

Prophylactic antibiotics has no benefit for outcome in clean myringoplasty-A register-based cohort study from SwedEar.

OBJECTIVES: To investigate if prophylactic antibiotics (PA) in conjunction with myringoplasty of clean and uninfected ears entails a reduction of postoperative infections within 6 weeks after surgery, and whether it affects the healing rate of the tympanic membrane (TM) at follow-up, 6-24 months after surgery. DESIGN: A retrospective cohort study of prospectively collected data. SETTING: Data extracted from The Swedish Quality Register for Ear Surgery (SwedEar), the years 2013-2019. PARTICIPANTS: All patients in SwedEar with a registered clean conventional myringoplasty (tympanoplasty type I) including a follow-up visit. MAIN OUTCOME MEASURES: The effect of PA use on TM healing rate at follow-up and postoperative infection within 6 weeks of surgery. RESULTS: In the study group (n = 1665) 86.2% had a healed TM at follow-up. There was no significant difference between the groups that had PA administered (87.2%) or not (86.1%). A total of 8.0% had a postoperative infection within 6 weeks. Postoperative infection occurred in 10.2% of the group that received PA (n = 187) compared with 7.7% of the group that did not receive PA. However, this difference was not statistically significant. Postoperative infection within 6 weeks significantly lowered the frequency of healed TMs. CONCLUSION: PA administered during clean conventional myringoplasty does not improve the chance of having a healed TM at follow up, nor decrease the risk of having a postoperative infection within 6 weeks after surgery.

Postoperative Outcomes After Tympanoplasty for Active Versus Inactive Otitis Media Patients With Tympanic Membrane Perforation: A Systematic Review and Meta-Analysis.

OBJECTIVES: To compare postoperative tympanoplasty outcomes between active versus inactive otitis media (OM) patients with tympanic membrane perforation. DATABASES REVIEWED: Medline via PubMed, Embase, Web of Science, Cochrane Central Register of Controlled Trials, and Google Scholar for studies published from inception to March 1, 2023. METHODS: Studies of 15- to 60-year-old patients undergoing microscopic/endoscopic myringoplasty using underlay/overlay technique with reported postoperative mean hearing gain and graft uptake were included. Studies requiring simultaneous surgical procedures, reporting patients with comorbidities and with non-English full text articles were excluded. Articles were independently screened by two researchers with data extracted according to a predetermined proforma in Microsoft Excel. Cochrane risk-of-bias assessment was used for risk of bias evaluation of randomized studies and Risk of Bias in Nonrandomized Studies of Interventions for nonrandomized studies. Similar studies were pooled for meta-analysis using the inverse variance random effects model to calculate the mean difference and corresponding 95% confidence interval (CI) for mean hearing gain and DerSimonian and Laird random effects model for graft uptake. RESULTS: Thirty-three studies comprising 2,373 patients met the inclusion/exclusion criteria, seven were pooled for meta-analysis. Included articles showed inactive OM patients have higher average postoperative mean hearing gain of 10.84 dB and graft uptake of 88.7% compared to active OM patients (9.15 dB and 84.2%). Meta-analysis of mean hearing gain (MD, -0.76 dB; 95% CI, -2.11 to 0.60; p = 0.27, moderate certainty) and graft uptake (OD, 0.61; 95% CI, 0.34-1.09; p = 0.10, moderate certainty) have an overall p value >0.05. CONCLUSION: There were no statistically significant differences in postoperative mean hearing gain and graft uptake between active and inactive OM patients undergoing tympanoplasty. Hence, tympanoplasty procedures should not be postponed solely because of patients' preoperative ear discharge status.

Plasma-Rich Fibrin-Regenerative Material in Tympanic Membrane Surgery.

Background and Objectives: Platelet-rich fibrin (PRF) membrane plays an important role in cell proliferation and aids in healing. This study aimed to assess the safety and efficacy of the addition of PRF to the graft in tympanoplasty. Materials and Methods: A retrospective study was conducted involving 47 patients with chronic dry eardrum perforation, who were candidates for different types of tympanoplasty (type I-IV). The study took place in the ENT department, County Emergency Clinical Hospital of Cluj-Napoca. In group 1 (27 patients) tympanoplasty was performed with a cartilage graft, while in group 2 (20 patients) a cartilage graft was used with the addition of a PRF membrane. The PRF clot was extracted and transformed into a thin membrane. Postoperative evaluation included otoendoscopy and otomicroscopy at 1, 3, 6, and 12 months after surgery, as well as pure-tone audiometry at 12 months. Results: Postoperative follow-up at 1, 3, 6, and 12 months showed a higher rate of graft survival in the PRF group than in the non-PRF group. At the 12-month mark, a successful outcome was observed in 95.0% of patients in the PRF group, while the success rate in group 1 was 70.4% (p < 0.05). The postoperative hearing threshold value was statistically significantly lower in the group with PRF, compared to the non-PRF group, being 18.4 ± 10.4 dB and 27.6 ± 16.2 dB (p < 0.001), respectively. Although the postoperative air-bone gap value did not differ significantly between groups, there was a greater improvement in the PRF group (p < 0.7). The PRF was well tolerated, and the incisions healed perfectly. Conclusions: The PRF membrane increases the rate of autograft survival and is therefore an effective material for patients with chronic perforations of the tympanic membrane.

[Application of allogenous dural membrane (brefotissue DM) in surgical treatment of retraction pockets of the tympanic membrane]. / Primenenie allogennoi tverdoi mozgovoi obolochki (brefotkan' tverdoi mozgovoi obolochki) pri khirurgicheskom lechenii retraktsionnykh karmanov barabannoi pereponki.

INTRODUCTION: The tactics of treating patients with retraction pockets of the tympanic membrane is still debatable. When choosing surgical treatment, preference is given to the removal of the retraction pocket with simultaneous reconstruction of the posterior-upper wall of the external auditory canal (retraction area) with a cartilage or fascial flap, autologous bone, or a combination of the above tissues. Considering the well-known negative aspects of the use of all the mentioned grafts, there is a need to find new types of tissues to strengthen the retraction pocket. For example, dura mater brefotissue has good plastic properties, resistance to infection, is easy to prepare, store, and is cheaper than many allografts. AIM: Evaluation of the possibility of using dura mater brefotissue in the surgical treatment of patients with retraction pockets of the tympanic membrane. MATERIALS AND METHODS: The study included 52 patients who underwent surgery to eliminate the retraction pocket. All of them were divided into 2 groups. In the first - the main (n=25) cartilage of the auricle was used to seal the relaxed part of the tympanic membrane, in the second - the control (n=27) applied tissue of the dura mater. After 1, 3, 6 and 12 months, to assess the result of the intervention, all patients underwent otomicroscopy, audiometry with the calculation of the average sound conduction index for speech frequencies. RESEARCH RESULTS: Fewer cases (4 patients out of 27) had difficulty in graft placement with the use of dura mater compared to the group where cartilage was used (9 patients out of 25). The average duration of graft placement was 8±0.5 minutes in the control group and 2±0.3 minutes in the main group. A stable morphological result was obtained in the group with the use of brefotissue in 26 patients (96%) and only in 20 patients (80%) with the use of cartilage. It is important to note that in the group with the use of brefotissue, in the early postoperative period, there was an increase in the air-bone interval, and 1 month after the operation, the average values increased by 10±0.5 dB. 12 months after the operation, the above parameters returned to preoperative. CONCLUSION: The conducted study indicates that the dura mater brefotissue, having sufficient strength, the convenience of forming a given shape and placing it in the desired position, can be successfully used in the surgical treatment of patients with retraction pockets of the tympanic membrane.

["Step-up"surgical treatment strategy for patulous Eustachian tube].

Patients with patulous Eustachian tubes(PET) usually suffer from annoying symptoms, such as tinnitus, autophony and aural fullness, due to the excessive opening of the Eustachian tube. There is no uniform standard of treatment, and conservative therapy combined with"Stepup"surgical intervention strategy is the main treatment. In this article, we reviewed various surgical treatments of patulous Eustachian tube in recent years, including key points of surgical operation, effectiveness, safety and complications. Full communication and evaluation are needed to establish appropriate patients' expectations preoperatively. A "Stepup" treatment strategy will be carried out, including conservative treatment, tympanic membrane surgery, Eustachian tube pharyngeal orifice constriction surgery, Eustachian tube tympanic orifice plug surgery and Eustachian tube muscle surgery, which aims to maintain normal Eustachian tube function and good middle ear ventilation.

Management of attic retraction pockets.

OBJECTIVE: Attic retraction pockets, classified by degree of invasion and erosion, are reconstructed here as outlined by attic retraction pocket grade. METHOD: Attic retraction pocket grade, surgical management, subsequent conditions of tympanic membrane and middle ear, and improvement of air-bone gap pure tone average were recorded. RESULTS: Our management strategy, based on attic retraction pocket grade, was applied to 200 ears: 44 grade I ears had non-surgical management and 156 grade II-V ears had surgical management. All 200 ears were followed up for 36-240 months, showing only 1 attic retraction pocket reformation and 1 adhesive otitis media (complication rate of 1 per cent), and improved air-bone gaps (p < 0.05). An earlier series of 50 grade IV attic retraction pockets used atticotomy with epitympanic reconstruction. These showed attic retraction pocket recurrence or cholesteatoma onset in 34 ears (68 per cent). When these ears were revised per protocol, there was no evidence of cholesteatoma thereafter. CONCLUSION: Reconstruction of the ossicles and scutal defect according to attic retraction pocket grade shows long-term stability of the tympanic membrane, middle ear and hearing.

Effect of Packing Versus No Packing in Transperforation Myringoplasty for Chronic Tympanic Membrane Perforations.

OBJECTIVE: To compare the operation times, graft survival and success rates, audiometric outcomes, and complications of patients who underwent transperforation myringoplasty with and without packing but without perforation rimming. STUDY DESIGN: A prospective, randomized controlled trial. SETTING: A university-affiliated teaching hospital. METHODS: We conducted a randomized controlled trial that enrolled patients who underwent underlay myringoplasty. No patient underwent perforation rimming. Patients underwent myringoplasty with or without graft lateral packing. The operation times, graft survival and success rates, audiometric outcomes, and complications were compared between the 2 groups. RESULTS: Sixty patients with unilateral perforations were included. The mean neovascularization score at postoperative week 2 was significantly higher in the no-packing group than in the packing group (p < .01) but did not differ significantly at postoperative weeks 3 and 4, or postoperative month 3. Neither the graft healing rate (p = .313) nor the perforation closure rate (p = .640) significantly differed between the 2 groups. The mean air-bone gap improved by 8.91 ± 5.45 dB in the packing group and 8.17 ± 1.19 dB in the no-packing group (p = .758). CONCLUSION: The long-term graft success and hearing improvements in transperforation myringoplasty with no rimming of the perforation and no-graft lateral packing were comparable to those in the graft lateral packing group with no rimming of the perforation, with a low incidence of complications. These results may change the traditional practice of packing the external auditory canal and rimming the perforation in underlay myringoplasty, even for all myringoplasty surgery.

Endoscopic transcanal surgery of pars tensa cholesteatoma: Preliminary results.

INTRODUCTION AND OBJECTIVES: The aim of the present study is the assessment of exclusive endoscopic ear surgery for the management of primarily acquired pars tensa cholesteatoma, which is commonly linked to the failure of the Eustachian tube leading to the formation of retraction pockets. MATERIALS AND METHODS: Patients suffering from primarily acquired pars tensa cholesteatoma, who underwent primary surgery in our clinic, between 2014 and 2018 were included in this retrospective study. The disease was classified according to the EAONO/JOS system. Exclusive endoscopic ear surgery was performed for patients without mastoid involvement, while a microscopic-endoscopic tympanoplasty was carried out in case of mastoid extension. We assessed the recidivism rate during the follow-up. RESULTS: Cholesteatomas belonged to stage I in 28% of cases, to stage II in 68% and only one patient was stage III. Only a portion of the pars tensa was involved in 13 instances, the whole pars tensa in 3 and both the tensa and the flaccida in 9. 17 out of 25 patients underwent exclusive endoscopic ear surgery and 8 needed a combined approach. We discovered 1 recurrence and 6 residual diseases. CONCLUSIONS: With only one case of recurrence in our series, we showed how pars tensa cholesteatoma cannot be exclusively explained through Eustachian tube dysfunction, but also through a ventilation blockage between the Eustachian tube and other mesotympanic areas due to the formation of intratympanic folds. Endoscopic ear surgery proved highly effective in the control of recurrences and it should be considered the treatment of choice.

An Innovative Tympanoplasty-Sleeve&Tongue Technique.

An innovative tympanoplasty method, blending the merits of traditional overlay and underlay techniques while avoiding the pitfalls. It enhances visualization, facilitates placement of the graft and preserves excellent blood supply, helps secure the fascia in place, as well as preserves the central-dented conical shape of the tympanic membrane.
