ABSTRACT

PURPOSE: To evaluate outcomes following explantation of percutaneous or transcutaneous bone conduction implants (pBCIs or tBCIs) and subsequent implantation of transcutaneous active bone conduction hearing devices (BCHDs); to provide guidance regarding staging of surgery and adjunctive procedures. MATERIALS AND METHODS: Retrospective chart review of eight adult subjects (ten ears) with pBCIs or tBCIs who underwent explantation of their device and subsequent implantation with a BCHD [MED-EL BONEBRIDGE™ (n = 7, 70 %) or Cochlear™ Osia® (n = 3, 30 %)]. RESULTS: Reasons for pBCI or tBCI explantation were pain (60 %, 6/10), infection (60 %, 6/10), skin overgrowth (50 %, 5/10), and inability to obtain new processors (20 %, 2/10). Median time between pBCI or tBCI removal and BCHD staged implant was 4.7 (IQR 2.2-8.1) months. Two subjects developed complications following BCHD implantation. One had a persistent wound overlying the osseointegrated screw after removal of the pBCI abutment, requiring removal and temporalis rotational flap. Staged Osia® implantation was performed, but ultimately wound dehiscence developed over the device. The second subject experienced an infection after BONEBRIDGE™ implantation (32 days after pBCI explant), necessitating washout and treatment with intravenous antibiotics. There was subsequent device failure. CONCLUSION: The transition from a pBCI or tBCI to a novel transcutaneous device is nuanced. Staged pBCI or tBCI explantation and novel BCHD implantation with sufficient time for wound healing is vital. Adjunctive procedures to augment soft tissue in cases of prior attenuation may be required to avoid complications with larger internal devices.

ABSTRACT

PURPOSE: Recent studies have suggested that children with an isolated cleft lip (CL) are more likely to develop middle ear disease and eustachian tube dysfunction (ETD) compared to the general population. This may be related to abnormal palatal musculature or an undiagnosed submucosal cleft palate (SMCP). We aim to determine the prevalence of SMCP in patients with CL who exhibit ETD. MATERIALS AND METHODS: A retrospective chart review was performed for children with an isolated CL requiring tympanostomy tubes over a 20-year period at an academic tertiary care medical center. Demographic, clinical, and surgical data were collected. RESULTS: Three hundred twelve patients had an isolated CL, and 29 (9.3 %) children required tympanostomy tubes. Of those, nine (31 %) were found to have a SMCP (7 males, 6 Caucasian). The average age at CL repair was 3.94 ± 1.03 months, and the average age at tympanostomy tube placement was 13.68 ± 13.8 months. All nine patients had chronic otitis media, with four having mild conductive hearing loss and three having moderate conductive hearing loss. The SMCP was diagnosed at the time of CL diagnosis (4), after CL diagnosis with the diagnosis of chronic otitis media/ETD (2) and after a diagnosis of chronic otitis media/ETD. CONCLUSION: Middle ear disease or eustachian tube dysfunction in a patient with an isolated cleft lip should raise suspicion for an accompanying undiagnosed SMCP.

ABSTRACT

INTRODUCTION: Congenital ossicular chain anomalies are rare conductive hearing loss conditions that remain difficult to diagnose even with high-resolution computed tomography (CT). The preoperative diagnosis is helpful for surgical planning and counseling patients regarding treatment outcomes. CASE PRESENTATION: We report a case involving a 14-year-old boy presenting with left conductive hearing loss without history of trauma for 5 years, physical examination showed normal otoscopic examination bilaterally and high-resolution CT showed absent of stapes suprastructure and footplate. Subsequent diagnosis was done via endoscopic middle ear exploration which revealed an absent long process of the incus, stapes suprastructure and footplate, but with intact oval window membrane. The residual incus was removed, and a tragal perichondrium graft was used over the oval window. A total ossicular replacement prosthesis was placed between the malleus and oval window to repair the chain. Postoperatively, the patient had no complications. Preoperative pure tone average revealed an air/bone result of 52/8 dB. Follow-up after surgery at 6 months showed a pure tone average air/bone result of 15/3 dB. The air-bone gap was reduced from 44 to 12 dB. CONCLUSION: Congenital absence of the stapes suprastructure and footplate remains a rare condition compared to the myriad of middle ear anomalies in the literature.

ABSTRACT

OBJECTIVE: Tophaceous lesions of the middle ear from calcium pyrophosphate deposition disease (CPPD, or pseudogout) and gout are infrequently reported. Recognizing its characteristic findings will allow clinicians to accurately narrow the differential diagnosis of bony-appearing middle ear lesions and improve management. PATIENTS: Two consecutive cases of tophaceous middle ear lesions presenting to a tertiary care center between January 2021 and December 2021. Neither with previous rheumatologic history. INTERVENTIONS: Surgical excision of tophaceous middle ear lesions. MAIN OUTCOME MEASURE: Improvements in facial weakness and conductive hearing loss. RESULTS: The first case was a 66-year-old gentleman with progressive conductive loss, ipsilateral progressive facial weakness over years, and an opaque, irregular-appearing tympanic membrane anterior to the malleus found to have CPPD on surgical pathology, with immediate postoperative improvement of facial function. The second was a 75-year-old gentleman with progressive conductive loss and similar appearing tympanic membrane as case 1, previously diagnosed with tympanosclerosis, found to have gout on surgical pathology. In both cases, the CT showed a heterogenous, bony-appearing lesion in the middle ear, and both tophaceous lesions were a of gritty, chalky consistency intraoperatively. CONCLUSION: Tophaceous lesions of the middle ear are rare but have similar findings. Notably, the tympanic membrane can appear opaque and irregular, and the CT demonstrates a radiopaque, heterogeneous appearance. Facial weakness is an unusual finding. Specimens of suspected tophi must be sent to pathology without formalin for accurate diagnosis.

ABSTRACT

BACKGROUND: Tympanic membrane perforation due to inactive mucosal chronic suppurative otitis media is a common problem in otolaryngology, with consequent conductive hearing loss. Still, there is controversy about the relationship between the location of the tympanic membrane perforation and the degree of hearing impairment. AIM OF THE STUDY: To assess the correlation between the location of a small tympanic membrane perforation and the degree of conductive hearing loss in adult patients with inactive mucosal chronic suppurative otitis media. PATIENTS AND METHODS: A prospective cross-sectional study enrolled 74 adult patients with small tympanic membrane perforations (perforation involves less than one quadrant of the tympanic membrane) and conductive hearing loss (airbone gap ≥ 20 dB HL) due to inactive mucosal chronic suppurative otitis media for at least 3 months. The locations of the tympanic membrane perforations were classified as anterosuperior, anteroinferior, posterosuperior, and poster inferior perforations. Audiometric analysis and a CT scan of the temporal bone were done for all patients. The means of the air and bone conduction pure tone hearing threshold averages at frequencies 500, 1000, 2000, and 4000 Hz were calculated, and consequently, the air-bone gaps were calculated and presented as means. The ANOVA test was used to compare the means of the air-bone gaps, and the Scheffe test was used to determine if there were statistically significant differences regarding the degree of conductive hearing loss in relation to different locations of the tympanic membrane perforation. RESULTS: The ages of the patients ranged from 20 to 43 years (mean = 31.9 ± 6.5 years), of whom 43 (58%) were females and 31 (42%) were males. The means of the air-bone gaps were 32.29 ± 5.41 dB HL, 31.34 ± 4.12 dB HL, 29.87 ± 3.48 dB HL, and 29.30 ± 4.60 dB HL in the posteroinferior, posterosuperior, anteroinferior, and anterosuperior perforations, respectively. Although the air-bone gap's mean was greater in the posteroinferior perforation, statistical analysis showed that it was insignificant (P-value=0.168). CONCLUSION: In adult patients with inactive chronic suppurative otitis media, the anteroinferior quadrant is the most common location of the tympanic membrane perforation, and there was an insignificant correlation between the location of a small tympanic membrane perforation and the degree of conductive hearing loss.

ABSTRACT

Isolated malleus fractures are a rare occurrence with few reported cases in the literature. Symptoms include sudden otalgia, hearing loss, tinnitus and aural fullness. Work-up and diagnosis are based on a combination of thorough anamnesis and careful otoscopic evaluation or high-resolution computer tomography. We present two cases of isolated malleus handle fractures who were diagnosed based on a combination of pneumatic otoscopy and tympanometry. Both fractures were surgically repaired using hydroxyapatite bone cement as showcased in the supplemental video material. Post-operative audiometry showed improvement in the pure-tone-average of both patients as well as normalisation of tympanometry. Isolated malleus fracture should be suspected in cases of sudden hearing loss and tinnitus following digital manipulation of the outer ear canal together with a conductive hearing loss with a mostly high-frequent air-bone-gap and hypercompliant tympanometry with hypermobility of the tympanic membrane on pneumatic insufflation. Surgical repair of the fracture using bone cement has good hearing outcomes and leads to improvement in auditory symptoms.

ABSTRACT

BACKGROUND: Cocaine is one of the most used recreational drugs. Whilst medical uses exist, chronic recreational nasal use of cocaine is associated with progressive destruction of the osseocartilaginous structures of the nose, sinuses and palate - termed cocaine-induced midline destructive lesions. CASE REPORT: A 43-year-old male with a history of chronic cocaine use, presented with conductive hearing loss and unilateral middle-ear effusion. Examination under anaesthesia revealed a completely stenosed left Eustachian tube orifice with intra-nasal adhesions. The adhesions were divided and the hearing loss was treated conservatively with hearing aids. Whilst intra-nasal cocaine-induced midline destructive lesions are a well-described condition, this is the first known report of Eustachian tube stenosis associated with cocaine use. CONCLUSION: This unique report highlights the importance of thorough history-taking, rhinological and otological examination, and audiometric testing when assessing patients with a history of chronic cocaine use. This paper demonstrates the complexity of managing hearing loss in such cases, with multiple conservative and surgical options available.

ABSTRACT

OBJECTIVE: To analyze the rates of complications after pediatric temporal bone fractures (TBF) and the utility of the longitudinal, transverse, and mixed versus the otic capsule sparing (OCS) and otic capsule violating (OCV) classification systems in predicting these complications. DATA SOURCES: PubMed, Scopus, and CINAHL. REVIEW METHODS: Per PRISMA guidelines, studies of children with TBFs were included. Meta-analyses of proportions were performed. RESULTS: A total of 22 studies with 1376 TBFs were included. Children with TBF had higher rates of conductive hearing loss (CHL) than sensorineural hearing loss (SNHL) (31.3% [95% confidence interval [CI] 23.2-40.1] vs 12.9% [95% CI 8.9-17.5]). No differences in both CHL and SNHL were seen between longitudinal and transverse TBFs; however, OCV TBFs had higher rates of SNHL than OCS TBFs (59.3% [95% CI 27.8-87.0] vs 4.9% [95% CI 1.5-10.1]). Of all patients, 9.9% [95% CI 7.2-13.1] experienced facial nerve (FN) paresis/paralysis, and 13.4% [95% CI 5.9-23.2] experienced cerebrospinal fluid otorrhea. Transverse TBFs had higher rates of FN paresis/paralysis than longitudinal (27.7% [95% CI 17.4-40.0] vs 8.6% [95% CI 5.2-12.8]), but rates were similar between OCS and OCV TBFs. CONCLUSION: CHL was the most common complication after TBF in children; however, neither classification system was superior in identifying CHL. The traditional system was more effective at identifying FN injuries, and the new system was more robust at identifying SNHL. While these results suggest that both classification systems might have utility in evaluating pediatric TBFs, these analyses were limited by sample size. Future research on outcomes of pediatric TBFs stratified by type of fracture, mainly focusing on long-term outcomes, is needed.

ABSTRACT

OBJECTIVE: To describe the post-operative complications and audiological results related to percutaneous bone-anchored hearing devices. METHODS: A retrospective review was conducted of 44 patients with bilateral conductive or mixed hearing loss who were implanted with unilateral Baha Connect or Ponto devices. A generalised linear model for repeated measurements was used. RESULTS: Twenty patients were Baha Connect users, and 24 were implanted with Ponto devices. Twenty-seven patients experienced complications. No fewer complications were found in the group of patients using longer abutments. When we compared the frequency of complications between Ponto and Baha Connect users, there was no statistically significant difference (p = 0.90). Free-field hearing thresholds were statistically significantly improved when we compared pre- and post-operative results (p < 0.001). Average speech perception also improved (p < 0.001). CONCLUSION: Despite percutaneous bone-anchored hearing devices having a high rate of complications, they provide significant audiological benefits.

ABSTRACT

OBJECTIVE: To analyze and compare the early and late post-operative results of glass ionomer bone cement (GIBC) used in ossiculoplasty. METHODS: The pre-operative, early post-operative (3 months) and late post-operative (> 2 years) audiometric findings, namely the pure-tone average (PTA), bone conduction threshold (BCT) and air-bone gap (ABG) of 40 patients who underwent GIBC ossiculoplasty for different etiologies were analyzed. Early and late results were compared. Also, the patients were grouped in terms of prognostic factors and applied ossiculoplasty techniques, and the results were compared between the groups. RESULTS: There were statistically significant improvements in the pure-tone average and air-bone gap of the patients in the early post-operative period (PTA from 59.60 ± 15.95 to 40.37 ± 17.83 and ABG from 37.12 ± 11.18 to 19.78 ± 10.41, p < 0.001 for both). There were no statistically significant changes in any of the audiometric parameters in the late post-operative period (PTA from 40.37 ± 17.83 to 39.79 ± 17.91, ABG from 19.78 ± 10.41 to 19.32 ± 9.60, BCT from 17.99 ± 12.71 to 18.31 ± 13.99, p > 0.05 for all). Presence of tympanosclerosis was found to be the only prognostic factor to affect the outcome. CONCLUSION: GIBC is a safe and reliable material for ossiculoplasty, which maintains its ability to conduct sound in the long-term follow-up.

ABSTRACT

OBJECTIVE: To report the largest case series of isolated malleus fractures with systematic review to characterize the disease's presentation and natural history, and provide suggestions for management. DATA SOURCES: PubMed, Embase, Cochrane Library. REVIEW METHODS: Retrospective cohort study was performed on 12 patients with isolated malleus fractures. History, physical exam, pre- and post-treatment audiograms, and imaging were obtained. Systematic review of the literature was performed. RESULTS: Including the cases herein, 58 isolated malleus fractures were identified, the majority of which were published in the 21st century. Mean time to presentation after injury was 34.4 months. Most common etiology was external auditory canal (EAC) manipulation. Physical exam and imaging did not identify any abnormality at presentation in 16% and 21% of cases, respectively. The majority of fractures involved the manubrium. Air-bone gap (ABG) at initial presentation ranged from 16 to 26 dB, and was greater at higher frequencies. Thirty-six cases underwent surgery. ABG improvement was greater at all frequencies for those who underwent surgery. Final ABG was significantly less than initial ABG at nearly every frequency for those who underwent surgery (p < 0.05), while not at any frequency for those who were observed. CONCLUSIONS: Isolated malleus fractures may occur more often than historical data suggests, and are perhaps underdiagnosed. Abrupt removal of a finger from the EAC with pain and hearing loss is nearly pathognomonic. Conductive hearing loss with ABG greater at higher frequencies is most often observed. Observation is unlikely to produce spontaneous improvements in hearing, while surgery demonstrates reliable decreases in ABG. Laryngoscope, 134:1032-1041, 2024.

ABSTRACT

OBJECTIVES: The objectives of the present study were to investigate the relationship between wideband absorbance (WBA) and air-bone gap (ABG) in children with a conductive hearing loss (CHL) due to otitis media with effusion (OME) and determine the accuracy of WBA to predict the magnitude of ABGs. DESIGN: This was a prospective, cross-sectional study involving a control group of 170 healthy ears from 130 children (mean age 7.7 years) and a CHL cohort of 181 ears from 176 children (mean age 5.9 years) with OME. The CHL cohort was divided into three groups: CHL1, CHL2, and CHL3 defined by mean ABG (averaged across 0.5 to 4 kHz) of 16 to 25 dB, 26 to 35 dB, and 36 to 45 dB, respectively. WBA was measured at frequencies from 0.25 to 8 kHz at ambient pressure. RESULTS: WBA was significantly reduced between 0.25 and 5 kHz for all CHL groups. The difference in WBA at 1 to 4 kHz between the control and CHL groups increased with increasing ABG. The predictive accuracy, as indicated by area under the receiver operating characteristic curve (AUROC) of WBA, increased with increasing ABG. The AUROC for WBA at 1.5 kHz was 0.86 for the CHL1, 0.91 for the CHL2, and 0.93 for the CHL3 group. The AUROCs for WBA averaged across 0.5 to 4 kHz were 0.88, 0.93, and 0.94 for the CHL1, CHL2, and CHL3 groups, respectively. Linear regression analyses showed significant negative correlations between WBA 0.5-4 k and ABG 0.5-4 k . The regression model (ABG 0.5-4 k = 31.83 - 24.08 × WBA 0.5-4 k ) showed that WBA 0.5-4 k predicted ABG 0.5-4 k with high accuracy. Comparison of predicted and actual WBA on a different group of subjects revealed that at an individual level, the model predicted ABG between 16 and 35 with greater precision. CONCLUSIONS: There were significant strong correlations between WBA and ABG such that WBA decreased with increasing ABG. WBA demonstrated good discrimination accuracy with AUROC exceeding 0.88 for the 0.5 to 4 kHz and 1 to 4 kHz frequency bands. The WBA test holds promise for determining the severity of CHL in children with OME.

ABSTRACT

PURPOSE: Chronic obstructive Eustachian tube dysfunction (OETD) can lead to tympanic membrane (TM) retraction and middle ear effusion (MEE) which can cause conductive hearing impairment, which among other ear symptoms can lower the quality of life (QoL). In this prospective study we assess hearing results and subjective changes in QoL following balloon Eustachian tuboplasty (BET) in treatment of OETD. METHODS: Totally 25 ears with TM retraction and 18 ears with MEE due to chronic OETD underwent BET as the sole intervention. Outcomes including otoscopy, ability to perform the Valsalva maneuver, tympanometry, audiometry, Eustachian tube inflammation scale and the Glasgow Benefit Inventory questionnaire (GBI) were obtained on all patients preoperatively and 6 months postoperatively. RESULTS: Hearing thresholds improved statistically significantly (p < 0.05) with means of 3 dB in the TM retraction group and 9 dB in the MEE group. Total GBI results indicated a positive influence on patients' QoL. Valsalva success rate was 80% in patients with TM retraction and 67% in patients with MEE. Tympanometry results improved in 50% of TM retraction patients and in 33% of MEE patients. CONCLUSIONS: Here we demonstrated that the BET has a positive impact on patients' conductive hearing loss and QoL in patients with TM retraction or MEE. Results were better in TM retraction group than in MEE group.

ABSTRACT

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.

ABSTRACT

BACKGROUND: The active transcutaneous, partially implantable osseointegrated bone conduction system Cochlear™ Osia® (Cochlear, Sydney, Australia) has been approved for use in German-speaking countries since April 2021. The Osia is indicated for patients either having conductive (CHL) or mixed hearing loss (MHL) with an average bone conduction (BC) hearing loss of 55 dB HL or less, or having single-sided deafness (SSD). OBJECTIVES: The aim of this retrospective study was to investigate the prediction of postoperative speech recognition with Osia® and to evaluate the speech recognition of patients with MHL and in particular an aided dynamic range of less than 30 dB with Osia®. MATERIALS AND METHODS: Between 2017 and 2022, 29 adult patients were fitted with the Osia®, 10 patients (11 ears) with CHL and 19 patients (25 ears) with MHL. MHL was subdivided into two groups: MHL­I with four-frequency pure-tone average in BC (BC-4PTA) ≥ 20 dB HL and < 40 dB HL (n = 15 patients; 20 ears) vs. MHL-II with BC-4PTA ≥ 40 dB HL (n = 4 patients; 5 ears). All patients tested a bone conduction hearing device on a softband preoperatively. Speech intelligibility in quiet was assessed preoperatively using the Freiburg monosyllabic test in unaided condition, with the trial BCHD preoperatively and with Osia® postoperatively with Osia®. The maximum word recognition score (mWRS) unaided and the word recognition score (WRS) with the test system at 65 dB SPL were correlated with the postoperative WRS with Osia® at 65 dB SPL. RESULTS: Preoperative prediction of postoperative outcome with Osia® was better using the mWRS than by the WRS at 65 dB SPL with the test device on the softband. Postoperative WRS was most predictive for patients with CHL and less predictable for patients with mixed hearing loss with BC-4PTA ≥ 40 dB HL. For the test device on a softband, the achievable outcome tended to a minimum, with the mWRS tending to predict the realistically achievable outcome. CONCLUSION: Osia® can be used for the treatment of CHL and MHL within the indication limits. The average preoperative bone conduction hearing threshold also provides an approximate estimate of the postoperative WRS with Osia®, for which the most accurate prediction is obtained using the preoperative mWRS. Prediction accuracy decreases from a BC-4PTA of ≥ 40 dB HL.

ABSTRACT

BACKGROUND: Electrophysiological tests are often used to evaluate hearing loss in infants and young children with conductive hearing loss, no matter to quantify or characterize. However, there are advantages and disadvantages associated with the various electrophysiological tests that are currently available. Therefore, there is no gold standard test. This study aimed to compare the value of narrow-band (NB) CE-Chirp-induced auditory steady-state response (ASSR) and auditory brainstem response (ABR) for assessing hearing thresholds in children with conductive hearing loss. We hope to identify an effective electrophysiological testing method to evaluate conductive hearing loss and provide a reference for clinical hearing assessment of infants with conductive hearing loss. SUBJECTS: and Methods: We selected 27 children (41 ears) aged 3-6 years with otitis media with effusion (OME). Within 1 day, they underwent behavioral audiometry and NB CE-Chirp-induced ASSR and ABR tests in sequence. Pearson's correlation analysis was performed to compare behavioral audiometry thresholds and ASSR and ABR response thresholds at 500, 1000, 2000, and 4000 Hz. RESULTS: The behavioral audiometry thresholds of all children were strongly correlated with the response thresholds of the two electrophysiological tests, with correlation coefficients of 0.659, 0.605, 0.723, and 0.857 for ASSR, and 0.587, 0.684, 0.753, and 0.802 for ABR. The proportion of children with a difference of ≤10 dB between ASSR and behavioral audiometry thresholds or between ABR and behavioral audiometry thresholds was not high, especially in the low frequencies. ABR results were superior to ASSR results in terms of predicting actual hearing levels. At 0.5, 1, 2, and 4 kHz, the average differences between the behavioral hearing thresholds and ASSR thresholds in the 41 ears were 5.6, 5.7, 2, and 5.6 dB, respectively. The average differences between behavioral hearing thresholds and ABR thresholds was -5.6, -1.4, -6.8, and 3.2 dB, respectively. The hearing loss configuration of the ASSR exhibited a peaked pattern, similar to behavioral audiometry, whereas the ABR exhibited an ascending pattern. The time to perform the single-ear ASSR test was 5.9 min, whereas the ABR test took 17.0 min. CONCLUSION: ASSR and ABR induced by the NB CE-Chirp correlated well with behavioral audiometry in children with conductive hearing loss. The NB CE-Chirp ASSR has advantages in terms of testing time and hearing configuration evaluation, whereas ABR has better reliability than ASSR. However, the stability of ASSR and ABR induced by the NB CE-Chirp is poor, and the thresholds obtained cannot replace behavioral audiometry in evaluating the true hearing of children with conductive hearing loss. However, ASSR and ABR can be used as auxiliary tests for cross-validation.

ABSTRACT

Objective: To explore the safety and reliability of retrosigmoid approach BONEBRIDGE implantation in patients with auricle reconstruction using skin expansion flap. Methods: A retrospective analysis was conducted on 43 congenital aural atresia cases (43 ears) who underwent BONEBRIDGE implantation from September 2019 to January 2023 in Beijing Tongren Hospital. 30 males and 13 females were included in this work. The implantation age was 9-36 years old (median age=10 y/o). All cases underwent auricle reconstruction surgery using the posterior ear flap expansion method, with 36 cases using the single expanded postauricular flap method and 7 cases using two-flap method. BONEBRIDGE implant surgery was performed during the third stage of auricle reconstruction or after all stages. The hearing improvements were evaluated by comparing the changes in pure tone hearing threshold and speech recognition rate of patients before and after BONEBRIDGE implantation. Routine follow-up was conducted to observe the hearing results and complications. SPSS 14.0 software was applied for data statistical analysis. Results: All 43 patients healed well and had no surgical complications when discharge. The average bone conduction hearing threshold after surgery was (8.2±6.6) dBHL, and there was no statistically significant difference compared to the preoperative [(8.1±5.7) dBHL] (P=0.95). After surgery, the threshold of hearing assistance with power on was significantly lower than that without hearing assistance [(32.8±4.6) dBHL vs (60.5±5.5) dBHL], and the difference was statistically significant (P<0.001). The speech recognition rate of monosyllable words, disyllabic words and short sentences in quiet environment increased to 72%, 84%, and 98% respectively. The differences were statistically significant (P<0.001). The speech recognition rate of monosyllabic words, disyllabic words, and short sentences in noise environment was significantly increased by 70%, 80%, and 92% respectively (P<0.001). After a follow-up of 4 to 47 months (median=24 months), the hearing results were stable and the aesthetic outcomes were satisfying. One patient had delayed hematoma around coil of the implant. After aspiration and compressed dressing for one week, hematoma was not recurrent. Conclusion: For patients after auricle reconstruction using expanded postauricular flap, the preference of retrosigmoid approach is a good choice in terms of safety and reliability of operation, as well as aesthetic appearance.

ABSTRACT

A variety of congenital and acquired disorders result in pediatric conductive hearing loss. Malformations of the external auditory canal are invariably associated with malformations of the middle ear space and ossicles. Isolated ossicular malformations are uncommon. Syndromes associated with external and middle ear malformations are frequently associated with abnormal development of first and second pharyngeal arch derivatives. Chronic inflammatory disorders include cholesteatoma, cholesterol granuloma, and tympanosclerosis.

ABSTRACT

Acquired stenosis of the external ear canal (ASEEC) is a relatively uncommon condition. Stenosis or narrowing of the external ear canal (EEC) occurs lateral to the tympanic membrane resulting in a skin lined blind canal. Recurrent otorrhea, and conductive hearing loss are typical clinical features. Although ASEEC can be due to different etiologies, a common pathogenesis, namely an inflammatory cascade, has been implicated. Clinical evaluation, audiogram, and Computed tomography (CT scan) form the mainstay of diagnosis. Surgery is the primary modality for treatment. Restenosis is the most common postsurgical complication.
