[Ab] Resumo:OBJECTIVE: To discuss the different modalities for managing necrosis of the long process of the incus in revision stapedectomy on the basis of the degree of necrosis and compare the results with those reported in the literature. MATERIALS AND METHODS: Thirty-six patients underwent revision stapedectomy with the necrosis of the long process of the incus from 2009 to 2016. The patients were divided into three groups on the basis of the degree of necrosis. For group A (minimal necrosis), augmentation technique with bone cement was performed. For group B (partial necrosis), the cement plug technique was performed. For group C (sever necrosis), malleus relocation with malleovestibulopexy was performed using reshaped necrosed incus. Air and bone conduction thresholds at frequencies of 500-3000 Hz were reviewed pre- and postoperatively using conventional audiometry. The air-bone gap (ABG) and bone conduction thresholds were measured. RESULTS: Postoperative ABG was reduced to <10 dB in 28 cases (77.8%) and <20 dB in all cases (100%). There was no significant change in postoperative bone conduction thresholds. The mean patient follow-up duration was 23 (range, 18-36) months. The cement plug technique was used in 75% of cases. CONCLUSION: Managing necrosis of the long process of the incus in revision stapedectomy should be considered according to the degree of necrosis. The cement plug technique is considered to be a reasonable option in most cases. Malleus relocation with malleovestibulopexy is an effective alternative to prosthesis.

[Ab] Resumo:OBJECTIVE: Cholesteatoma patients have a high risk of recurrence with complications, and knowledge exchange is a prerequisite for improving treatment. This study aimed to apply appropriate statistics to provide meaningful and transferable results from cholesteatoma surgery, to highlight independent prognostic factors, and to assess the incidence rate. METHODS: Incidence rates were assessed for the district of Aarhus, Denmark. From 147 patients operated on mainly with canal wall up mastoidectomies for debuting cholesteatomas, 10-year Kaplan-Meier recidivism rates were calculated and independent prognostic factors for the recidivism were identified by Cox multivariate regression analyses. RESULTS: Incidence rate was 6.8 per 100 000 per year. The 10-year cumulative recidivism rate was 0.44 (95 per cent confidence interval, 0.37-0.53). Independent prognostic factors for the recidivism were: age below 15 years (hazard ratio = 2.2; p > z = 0.002), cholesteatoma localised to the mastoid (hazard ratio = 1.7; p > z = 0.04), stapes erosion (hazard ratio = 1.9; p > z = 0.02) and incus erosion (hazard ratio = 1.9; p > z = 0.04). CONCLUSION: The recidivism rate is influenced by several factors that are important to observe, both in the clinic and when comparing results from surgery.

[Ab] Resumo:OBJECTIVE: This study aimed to compare the functional and anatomical outcomes of ossiculoplasty using an autograft incus or a titanium partial ossicular replacement prosthesis for reconstructing Austin type A ossicular defects. METHODS: Patients with Austin A ossicular defects were randomly divided into two groups: one group underwent ossiculoplasty with an autologous incus (the autologous incus group) and the other underwent ossiculoplasty with a titanium partial ossicular replacement prosthesis (the titanium prosthesis group). Otoscopic examination and audiological assessment was done pre-operatively and at 3, 6 and 12 months post-operatively. RESULTS: A post-operative average air-bone gap closure of less than 20 dB was seen in 13 patients (65 per cent) in the autologous incus group and 7 (35 per cent) in the titanium prosthesis group. There were fewer post-operative complications in the autologous incus group (20 per cent) than in the titanium prosthesis group (45 per cent). CONCLUSION: Hearing outcomes and graft take up after ossiculoplasty were significantly better when an autologous incus rather than a titanium partial ossicular replacement prosthesis was used to reconstruct Austin type A ossicular defects. The major disadvantages of the titanium prosthesis were unpredictable results and more post-operative complications.

[Ab] Resumo:OBJECTIVE(S): To describe a new and more simple surgical procedure for implanting the Vibrant Soundbridge (VSB) on the short process of the incus in children with ear atresia and atretic plate and present the audiometric results. METHODS: Since 2014, pre- and post-operative audiometric tests with tonal and vocal audiometryat the maximal follow up, respectively 33, 22 and 12 months were performed after VSB implantation at the ENT department, Necker Enfants Malades Hospital, Paris, France. 3 children aged 11, 9 and 15 years with conductive hearing loss due to high grade ear atresia and absent ear canal were implanted. The malformed and fused malleus-incus complex was found to be immobile in two of the subjects, who then underwent a superior tympanotomy to carefully remobilize the malleus. Stapes were mobile in all cases. The FMT clip was customized and crimped on the short process, stabilized by the metallic wire. RESULTS: At the maximum follow-up time, the bone conduction was unchanged, and the mean aided ACPTA was 21 dB, 29 dB and 30 dB, compared to 66 dB, 63 dB and 68 dB unaided, respectively. The word recognition score (WRS) at 65 dB SPL increased from 10%, 10% and 70% (unaided) respectively to 100% (aided). CONCLUSIONS: The long process of the incus is usually very hypoplastic in patients with ear atresia with a fused malleus-incus complex lateral to the stapes. VSB coupling to the long process of the incus or the stapes may be challenging in small mastoids. Coupling to the short process of the incus is comparatively a simple procedure, since there is no need for posterior tympanotomy and has no proximity to the facial nerve. The results of this study are similar to other ear atresia cases in the literature with classic FMT placement on the stapes or long process of the incus. Outcomes should be confirmed in a larger number of patients.

[Ti] Título:Middle-Ear Sound Transmission Under Normal, Damaged, Repaired, and Reconstructed Conditions.

[Ab] Resumo:HYPOTHESIS: We hypothesize that current clinical treatment strategies for the disarticulated or eroded incus have the effect of combining the incus and stapes of the human middle ear (ME) into one rigid structure, which, while capable of adequately transmitting lower-frequency sounds, fails for higher frequencies. BACKGROUND: ME damage causes conductive hearing loss (CHL) and while great progress has been made in repairing or reconstructing damaged MEs, the outcomes are often far from ideal. METHODS: Temporal bones (TBs) from human cadavers, a laser Doppler vibrometer (LDV), and a fiber-optic based micro-pressure sensor were used to characterize ME transmission under various ME conditions: normal; with a disarticulated incus; repaired using medical glue; or reconstructed using a partial ossicular replacement prosthesis (PORP). RESULTS: Repairing the disarticulated incus using medical glue, or replacing the incus using a commercial PORP, provided similar restoration of ME function including almost perfect function at frequencies below 4 kHz, but with more than a 20-dB loss at higher frequencies. Associated phase responses under these conditions sometimes varied and seemed dependent on the degree of coupling of the PORP to the remaining ME structure. A new ME-prosthesis design may be required to allow the stapes to move in three-dimensional (3-D) space to correct this deficiency at higher frequencies. CONCLUSIONS: Fixation of the incus to the stapes or ossicular reconstruction using a PORP limited the efficiency of sound transmission at high frequencies.

[Ab] Resumo:To investigate the effects of surgery type [intact canal wall (ICW) or canal wall down (CWD) mastoidectomy] and different ossiculoplasty materials on hearing outcome in single-staged cholesteatoma surgery. A retrospective case-control study. A total of 116 cases (97 adults, 29 children) underwent surgery, including ossiculoplasty, between 2012 and 2015 for cholesteatoma. Patients who had undergone surgery for the first time, and whose grafts were successful, were included in the study. Patients with adhesive otitis media, unsuccessful grafts, revision and recurrent cases, radical mastoidectomy, and craniofacial anomalies were excluded. Audiogram examinations of the enrolled patients were performed 3-6 months after surgery, and the audiometric results were analyzed according to the criteria of the American Academy of Otolaryngology, Head and Neck Surgery. All ossiculoplasties were performed during the first operation. The preoperative average air-bone gap (ABG) of the patients was decreased from 31.37 ± 10.1 to 27.42 ± 10.4 dB; this decrease was found to be highly significant (p = 0.0001). Concerning the ICW technique, statistical evaluation of the hearing gain at frequencies of 500, 1000, and 2000 Hz, as well as the mean frequency, showed a high level of significance. Improvement at 4000 Hz was not found to be statistically significant. When the ABGs at 500, 1000, 2000, and 4000 Hz, and the mean frequency in patients with an hydroxyapatite-partial ossicular replacement prosthesis (HA-PORP) or autograft-partial ossicular replacement prosthesis (APORP), were evaluated, it was found that, at 4000 Hz, the APORP significantly reduced the ABG (p = 0.02). No significant difference was determined between patients with the hydroxyapatite-total ossicular replacement prosthesis (HA-TORP) and those with the autograft-total ossicular replacement prosthesis (ATORP) (p = 0.565). Although the use of the malleus as an APORP was found to be less effective than other autografts, the degree of advantage of using the incus, malleus, cortical bone, and cartilage did not significantly differ between materials (p = 0.152). Despite the effects of the incus, malleus, and cortical bone not differing in terms of the postoperative ABG (p = 0.160), incus usage was highly beneficial for hearing gain (p = 0.009). Despite CWD tympanoplasty affecting all frequencies, it has a particularly negative effect on the hearing threshold at 1000 Hz. In patients with partial ossicular replacement, autogenous grafts are more successful in restoring hearing at high frequencies, particularly at 4000 Hz. Although autogenous materials do not differ in terms of partial replacement effectiveness, the incus has been shown to be most effective for total replacement.

[Ti] Título:Early development of the malleus and incus in humans.

[Ab] Resumo:It is widely accepted by developmental biologists that the malleus and incus of the mammalian middle ear are first pharyngeal arch derivatives, a contention based originally on classical embryology that has now been backed up by molecular evidence from rodent models. However, it has been claimed in several studies of human ossicular development that the manubrium of the malleus and long process of the incus are actually derived from the second arch. This 'dual-arch' interpretation is commonly presented in otolaryngology textbooks, and it has been used by clinicians to explain the aetiology of certain congenital abnormalities of the human middle ear. In order to re-examine the origins of the human malleus and incus, we made three-dimensional reconstructions of the pharyngeal region of human embryos from 7 to 28 mm crown-rump length, based on serial histological sections from the Boyd Collection. We considered the positions of the developing ossicles relative to the pharyngeal pouches and clefts, and the facial and chorda tympani nerves. Confirming observations from previous studies, the primary union between first pharyngeal pouch and first cleft found in our youngest specimens was later lost, the external meatus developing rostroventral to this position. The mesenchyme of the first and second arches in these early embryos seemed to be continuous, but the boundaries of the developing ossicles proved to be very hard to determine at this stage. When first distinguishable, the indications were that both the manubrium of the malleus and the long process of the incus were emerging within the first pharyngeal arch. We therefore conclude that the histological evidence, on balance, favours the 'classical' notion that the human malleus and incus are first-arch structures. The embryological basis of congenital ossicular abnormalities should be reconsidered in this light.

[Ab] Resumo:OBJECTIVE: Magnetic resonance imaging (MRI) has become an essential tool of modern medical imaging and disease diagnosis. In November 2014, a new MRI-conditional (up to 1.5 T) generation of an active middle ear implant (AMEI) was released to the market.The aim of the study was to test the MRI compatibility of the new implant system in a clinical-anatomical study. DESIGN: Experimental cadaver head model. SETTING: Temporal bone laboratory. PARTICIPANTS: AMEIs were implanted in 28 fixed temporal bones at three different floating mass transducer (FMT)-coupling positions (N = 8 short process of the incus, N = 16 long process of the incus, N = 4 round window). MAIN OUTCOME MEASURES: The position of the FMT and the integrity of the ossicular chain was monitored through microscopy, microendoscopy, and computed tomography (CT) scans before and after the MRI (1.5 T) was conducted. Proper function of the implant was tested with reverse transfer function (RTF) measurements. RESULTS: Neither positional nor functional changes after MRI were observed. CONCLUSION: The new generation of the AMEI is a MRI-compatible system, which features an easier and quicker implant fixation method. The option of MRI in patients with AMEI should be taken into consideration during the preoperative discussion with potential candidates.
