Son HO, Moon S, Sung HJ, Choi JW. Endoscopic malleostapedotomy versus incudostapedotomy for stapes fixation with or without lateral chain fixation: A comparative outcomes study. Laryngoscope Investig Otolaryngol 2024; 9:e1273. [PMID: 38803459 PMCID: PMC11129549 DOI: 10.1002/lio2.1273] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2024] [Revised: 04/18/2024] [Accepted: 05/08/2024] [Indexed: 05/29/2024] Open
Abstract
Objectives This study aims to evaluate and compare the surgical outcomes of endoscopic malleostapedotomy (EMS) and endoscopic incudostapedotomy (EIS). Methods A retrospective analysis was conducted on 36 consecutive ears in 33 patients who underwent stapes surgery using either EMS (EMS group) or EIS (EIS group). Operational practicability across surgical steps, postoperative hearing, operation time, switch of approach, and complications were compared between the two groups. Results The EMS and EIS groups comprised seven (19.4%) and 29 ears (80.6%), respectively. The EMS group exhibited a greater proportion of moderate practicability in anchoring site exposure (42.9%, three of seven) and in securing the prosthesis (100%, seven of seven) in comparison to the EIS group, which had 0% (0 out of 29) and 41.4% (12 out of 29), respectively. Postoperative hearing improvements were equivalent between the groups, with EMS achieving a mean air-bone gap improvement of 28.8 dB and EIS of 23.2 dB. The ABG closure rates within 10 dB and 20 dB for the EMS group were 28.6% and 100%, respectively, and not significantly different from the EIS group (p = .103). However, the average surgical duration for EMS was extended by 77.4 min. The rate of complications was comparable between the groups (EMS 14.3%, EIS 10.3%, p = 1.000). Conclusion The findings indicate that while EMS requires a longer operation time because of decreased practicability in specific surgical steps, it provides comparable outcomes to EIS, underscoring the potential of endoscopic techniques to establish malleostapedotomy as a surgical option as it is with traditional incudostapedotomy. Level of Evidence 4.

Abstract
BACKGROUND Stapes ankylosis is a rare cause of conductive hearing loss, and stapes suprastructure fixation is extremely rare with fewer than 30 reported cases. Patients usually visit the clinic with non-progressive conductive hearing loss that typically began in the early years of life.
CASE SUMMARY Herein, we report a case of a 37-year-old female with an isolated stapedial suprastructure fixation. The patient presented with unusual fluctuating auditory symptoms of tinnitus, ear fullness and mixed hearing loss. Pre-operative temporal bone computed tomography findings and operative findings revealed an isolated stapedial suprastructure fixation with monopod stapes caused by elongated pyramidal eminence. The hearing threshold recovered completely, and fluctuating auditory symptoms disappeared after the surgery.
CONCLUSION This is the first report of stapedial suprastructure fixation with fluctuating auditory symptoms. Successful results are expected with surgical treatment.

Abstract
Objectives: In this study, we aim to analyze audiometric outcomes of middle ear surgery
in patients with congenital middle ear anomalies. Methods: In this single center retrospective cohort study, audiological outcomes were
extracted from patient files. Patients with a congenital middle ear anomaly
treated surgically in a tertiary referral center between June 2015 and
December 2020 were included. Pre- and postoperative short- and long-term
audiometric data (at ≥3 and ≥10 months respectively) were compared to
analyze hearing outcomes. Results: Eighteen ears (15 patients) were treated surgically with an exploratory
tympanotomy. At short term follow up statistically significant improvements
in air conduction thresholds and air-bone gaps were found. Hearing improved
in 94.4% (17/18) of operated ears. Successful outcome, defined as an
air-bone gap closure to within 20 dB after surgery, was reached in 44.4%
(8/18). Serviceable hearing (air conduction ≤30 dB) was reached in 55.6%
(10/18). Negative outcome (any significant deterioration in hearing)
occurred in 1 patient: in this ear otitis media occurred during the
postoperative course. At long term follow up, available for 50% of the
cohort, hearing remained stable in 5 ears, improved in 1 ear and
deteriorated in 3, all of which underwent revision surgery. Sensorineural
hearing loss due to surgery, or other complications, were not
encountered. Conclusion: middle ear surgery was found to be an effective treatment option to improve
hearing in this cohort of patients with congenital middle ear anomalies.
Surgical goals of obtained gain in air conduction thresholds and serviceable
hearing levels were met by most patients without the occurrence of any
iatrogenic sensorineural hearing loss.

Abstract
Objectives: To compare preoperative temporal bone high-resolution computed tomography (HRCT) readings to intraoperative findings during exploratory tympanotomy for suspected cases of isolated congenital middle ear malformations (CMEMs) and summarize the malformations that can and cannot be diagnosed with HRCT. Methods: A retrospective study was conducted. All cases were confirmed as isolated CMEMs during surgery. Detailed clinical records were reviewed, with a focus on imaging and surgical findings. Results: One hundred and thirty-two patients and 145 ears were reviewed. Ninety cases (62.1%) could be identified as isolated CMEMs and at least one as middle ear anomaly using preoperative HRCT. Fifty-five cases (37.9%) were reported to be completely normal and the patients underwent exploratory tympanotomy to determine the final diagnosis. Stapes fixation, either alone or associated with other ossicular chain anomalies, contributed to 53.1% of the cases. Most cases of aplasia or dysplasia of the ossicular chain, for example, aplasia/dysplasia of the long process of the incus, aplasia of the stapes’ superstructure, and atresia of the oval window were easily identified in preoperative HRCT. However, fixation of the ossicular chain can be elusive in HRCT, and exploratory tympanotomy is needed for a definitive diagnosis. Conclusions: HRCT provides helpful preoperative clinical information in CMEM and may obviate the need for middle ear exploration in some cases. The negative findings (anomalies that are difficult to identify through preoperative HRCT) and the positive findings (anomalies that are relatively easy to identify through preoperative HRCT) were summarized.

Abstract
Introduction: The aim of this work was to report and describe the different types of congenital middle ear malformations in order to guide surgical treatment approaches and improve outcomes for affected patients. Methods: The authors reviewed patients with congenital middle ear malformations who received surgical treatment between September 2010 and March 2017. Patient characteristics, middle ear deformities, and surgical procedures were documented. Results: In this retrospective study, 35 patients were reviewed. A description of middle ear malformation was proposed that considers ear embryogenesis and focuses on stapes deformity, with the main purpose of facilitating surgical approach selection to reconstruct the ossicular chain. Patients were classified into 3 categories: type I (19 cases), mobile stapes footplate, which included type Ia with normal stapes suprastructure and type Ib with abnormal stapes suprastructure; type II (4 cases), fixed stapes footplate, which included type IIa with normal ossicular chain and type IIb with abnormal ossicular chain; and type III (12 cases), oval window bony atresia or aplasia, with or without round window atresia. Types II and III could have concomitant aberrant facial nerve. Different surgical approaches are described. Conclusions: The authors describe the different types of congenital middle ear malformations. This category description considers ear embryogenesis and is focused on stapes deformity. It may provide better understanding of disease development and guide modern hearing reconstructive surgery.

Abstract
OBJECTIVE To analyze the results of malleostapedotomy performed by applying the self-fixing and articulated titanium piston according to Häusler. STUDY DESIGN Retrospective case review. SETTING Tertiary referral center. PATIENTS AND INTERVENTIONS This study concerns a retrospective analysis of the results of malleostapedotomy with the use of a self-fixing articulated titanium piston in 16 ears of 16 consecutively treated patients between 2005 and 2009. The medical files were used for the acquisition of data on medical and surgical history and to obtain pre- and postoperative audiometry. Diagnosis and outcomes of mainly revision surgeries are presented and compared to the literature. MAIN OUTCOME MEASURES Effect of (revision) malleostapedotomy by evaluating postoperative audiometry and air-bone gap closure. RESULTS The postoperative air-bone gap closure was ≤ 10 dB in 9/16 (56%) ears and within ≤ 20 dB in 13/16 (81%) ears. The mean postoperative air-bone gap was 14.3 dB HL (0.5-2.0 kHz) and 17.3 dB HL (0.5-4.0 kHz). Postoperatively, there was no increase in bone conduction thresholds larger than 3 dB (0.5-2.0 kHz) and postoperative dizziness was absent or very limited and transient. CONCLUSIONS The malleostapedotomy procedure has become surgically less demanding over time by the technical improvements present in the nowadays available pistons. The design of the self-fixing and articulated titanium piston used in the present group of patients allows a safe and straight-forward malleostapedotomy procedure. Present hearing outcomes match with results presented in the literature.

Abstract
Cholesteatomas that occur under an intact tympanic membrane in the absence of prior surgical procedures or perforation are defined as congenital cholesteatomas. These entities are rarely seen, because they do not cause any major symptoms unless they touch the ossicular chain. Likewise, isolated congenital ossicular anomalies that occur independently of external ear anomalies and craniofacial dysplasia are also rarely seen. Here, we report a patient who presented with congenital cholesteatoma associated with anomalies of the ossicular chain and discuss its pathogenesis.

Abstract
Objectives: We describe the audiometric results following surgery in a consecutive series of patients with a congenital ossicular middle ear disorder that was associated with a mobile stapes footplate. Methods: We performed a retrospective analysis of patient charts from a tertiary referral center. A total of 23 patients (23 ears) underwent exploratory tympanotomy and ossicular reconstruction between 1986 and 2001. The main outcome measure was the audiometric results. Results: Overall, we observed a mean gain in air conduction pure tone average of 17 dB (from 47 dB to 30 dB), a sensorineural deterioration of 3 dB, and a mean postoperative air-bone gap of 19 dB (mean preoperative air-bone gap of 38 dB). The air-bone gap closure was 20 dB or less in 15 of the 23 cases (65%), in agreement with the few results reported in the literature. Moreover, the audiometric results remained stable. In the syndromic group, the mean gain in air conduction was only 13 dB, which was worse than that observed for the nonsyndromic ears. Conclusions: Surgery for congenital ossicular chain anomalies with a concomitant mobile stapes footplate provides positive audiometric outcomes. Most ears had some sensorineural impairment (10 to 20 dB), which influenced the final hearing level attained after surgery. Preoperative assessment is mandatory to search for syndromal diagnoses, which might be important for patient counseling and prognosis.

Abstract
Congenital stapes ankylosis is reported to have an occurrence rate of 3% to 4%, and it represents 20% to 35% of ossicular malformations. Surgical treatment of congenital stapes ankylosis is described to be satisfactory in the large majority of the case series reported in the literature. In these cases, special attention should be paid to exclude any aberrations of the course of the facial nerve, which have been demonstrated to be frequently associated with congenital middle ear malformations. We describe a case of congenital stapes ankylosis associated with a previously unreported facial nerve abnormality, characterized by the presence of an empty fallopian canal in combination with a dehiscent facial nerve running over the footplate and almost totally covering it.

Abstract
OBJECTIVE This study aimed to use a new otological technique, malleus relocation, to solve the problems of ossicular reconstruction undertaken during revision stapes surgery for incus necrosis. STUDY DESIGN Prospective study of 12 patients undergoing revision stapedectomy for incus necrosis, in the otolaryngology department of Mansoura University, Egypt. PATIENTS AND METHODS Twelve patients underwent ossiculoplasty between June 2004 and June 2007, as part of revision surgery for otosclerosis with incus necrosis. All patients underwent ossiculoplasty using the malleus relocation technique. Ossiculoplasty used the patient's own, necrosed incus between the relocated malleus and the footplate. RESULTS Post-operative air-bone gap closure to within 10 dB was achieved in seven patients (58.3 per cent). An air-bone gap of less than 20 dB was obtained in 10 patients (83.3 per cent). Deterioration of bone conduction by 10 dB occurred in one case. No patients were left with a 'dead ear'. Patients' hearing was stable throughout the follow-up period (range six to 40 months; mean ± standard deviation 23.5 ± 12.8 months). CONCLUSION These findings indicate that malleus relocation, performed during revision stapes surgery, is a safe and efficient technique for the treatment of incus necrosis.
