Abstract
PURPOSE The association between microtia severity and hearing function has been thoroughly investigated. This study examined the relationship between microtia grade, number of ear subunits (i.e., helix, antihelix, scapha, triangularis fossa, concha, lobule, tragus, and antitragus) with auditory brainstem response (ABR) findings in children with microtia. STUDY DESIGN A retrospective chart review was employed in this study. METHOD We analyzed the ABR test results and photographs of 22 children with 30 microtia ears at Dr. Cipto Mangunkusumo National Hospital, Jakarta. The ABR test results were acquired using click (air conduction only) and 500-Hz tone burst stimuli (air- and bone-conduction). Ear photographs were overlaid with a template of a normal ear to determine the number of ear subunits present and the subsequent microtia grade. Number of ear subunits and ABR results were analyzed using the chi-square, Mann-Whitney U, and Spearman's correlation tests. RESULTS ABR thresholds for click and 500-Hz tone bursts air-conduction were significantly poorer for ears with a subunit < 5 compared to ears with a subunit ≥ 5. No significant difference was observed in 500 Hz bone-conduction ABR thresholds between these groups. Correlation analysis showed a significant negative correlation between increased ear subunits and click ABR thresholds. No significant correlation was found between ear subunits and 500-Hz air- and bone-conduction ABR thresholds. CONCLUSIONS A higher number of ear subunits are associated with a lower hearing threshold, as assessed using ABR with click stimuli. Therefore, the number of ear subunits and microtia grades can be used to examine the hearing level thresholds in infants and children with microtia.

Abstract
OBJECTIVES Microtia is a severe congenital malformation of the external ear, and auricular reconstruction is still a challenge for plastic surgeons because of the complicated procedures and rare conditions. This study aimed to describe the location of subcutaneous effusion after auricular reconstruction and explore the clinical efficacy of the indwelling needle puncture drainage method in the treatment of local subcutaneous effusion. METHODS From January 2017 to December 2019, 1240 patients (1296 affected sides) who underwent auricular reconstruction using autogenous cartilage framework in the Plastic Surgery Hospital of Chinese Academy of Medical Science and Peking Union Medical College were selected. The local subcutaneous effusion occurred within 5 days after the drainage tube was removed, and the indwelling needle was used for puncture and drainage in the postoperative treatment. RESULTS A total of 55 patients had subcutaneous effusion after the operation, including 24 cases with Nagata's method and 31 cases with the expanded single-flap method. One patient showed no obvious reduction after puncture and drainage by indwelling needle and improved after the secondary operation. Two patients had slight cartilage absorption. The remaining patients had good results. CONCLUSIONS The method of the indwelling needle for puncture and drainage is easy to operate. The problem of local subcutaneous effusion after auricular reconstruction can be solved and good efficacy can be obtained.

Otolaryngol Head Neck Surg 2023; 169:449-453. [PMID: 35439089 DOI: 10.1177/01945998221094230] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2021] [Accepted: 03/25/2022] [Indexed: 11/17/2022]
Abstract
OBJECTIVE Patients with congenital external auditory canal (EAC) abnormalities are at risk of developing cholesteatoma and often undergo surveillance imaging to detect it. The aims of this systematic review are to determine the incidence of cholesteatoma in patients with congenital aural atresia (CAA) and patients with congenital EAC stenosis and to investigate the most common age of cholesteatoma diagnosis. This information will help clinicians decide which patients require surveillance scanning, as well as the timing of imaging. DATA SOURCES Ovid MEDLINE, Embase, CENTRAL, and Web of Science databases. REVIEW METHODS A systematic literature review following the PRISMA guidelines was performed. The data sources were searched by 2 independent reviewers, and articles were included that reported on CAA or congenital EAC stenosis with a confirmed diagnosis of cholesteatoma. The selected articles were screened separately by 3 reviewers before reaching a consensus on the final articles to include. Data collection on the number of patients with cholesteatoma and the age of diagnosis was performed for these articles. RESULTS Eight articles met the inclusion criteria. The incidence of cholesteatoma was 1.7% (4/238) in CAA and 43.0% (203/473) in congenital EAC stenosis. The majority of patients with congenital EAC stenosis that developed cholesteatoma were diagnosed at age <12 years. CONCLUSION CAA is associated with a low risk of cholesteatoma formation, and surveillance imaging is unnecessary in asymptomatic patients. EAC stenosis is strongly associated with cholesteatoma, and a surveillance scan for these patients is recommended prior to 12 years of age with close follow-up into adulthood.

Satisfaction and health-related quality of life of patients with microtia following reconstructive surgery using the Nagata technique. PLoS One 2021; 16:e0256652. [PMID: 34469475 PMCID: PMC8409618 DOI: 10.1371/journal.pone.0256652] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2021] [Accepted: 08/11/2021] [Indexed: 11/21/2022] Open
Abstract
Objective This study aimed to investigate the functional outcomes, satisfaction, and quality of life of patients with microtia following reconstructive surgery. Methods This cross-sectional study was conducted using retrospective data of patients with microtia following reconstructive surgery using the Nagata technique. Data were obtained from the medical records of patients who underwent reconstructive surgery at the Division of Facial Plastic and Reconstructive Surgery, Department of Otorhinolaryngology, Head and Neck Surgery, Dr. Cipto Mangunkusumo Hospital between 2014 and 2018. All eligible patients were referred to participate in this study between November 2018 and March 2019. The hearing function was assessed by a professional audiologist after surgery. Patient satisfaction was evaluated by interview using a previously developed questionnaire, while quality of life was assessed using the EuroQol-5D-Young questionnaire. Results Thirty-one eligible subjects were included in the study. Pain and discomfort were the most commonly reported factors related to the quality of life following surgery. Approximately 67.7% of the patients were satisfied; 19.4% were very satisfied, and 12.9% reported acceptance of their surgical outcomes. The most common complication was infection (n = 8). Most patients did not experience any problems in their lives after microtia surgery. Conclusions The highest rate of satisfactory outcomes was observed for the lobule subunit, which was assumed to be associated with the use of the Z-plasty technique. The most common complication was infection, as environmental hygiene was the most important factor. Thus, further concern for maintaining good hygiene is necessary to improve the quality of reconstructive surgery. The level of satisfaction with microtia reconstructive surgery was adequate. Most patients had a good health-related quality of life without experiencing any problems.

Abstract
BACKGROUND Microtia is a severe congenital malformation of the external ear. This study aimed to explore the epidemiologic characteristics and the possible risk factors in patients with severe microtia in China, and integrate significant variables into a predictive nomogram. METHODS A total of 965 patients with microtia were included. This retrospective case study was conducted from July 2014 to July 2019 at Plastic Surgery Hospital in China. The detailed questionnaires concerning potential risk factors were completed and data were gathered. Chi-Square and Fisher tests were used to analyze the variables, and a multivariate logistic regression model was used to select variables related to severe microtia, and then construct a nomogram. The nomogram model was evaluated by the concordance index (C-index), calibration plot, and receiver operating characteristics (ROCs) curve. Bootstraps with 1000 resamples were applied to these analyses. RESULTS Of the 965 microtia patients, 629 (65.2%) were male and 867 (89.8%) were sporadic. The cases were observed more commonly in unilateral (83.1%) and right-sided (52.0%). And multiple malformations were observed in 392 (40.6%) cases. Multivariate logistic regression analysis showed that maternal age, miscarriage frequency, virus infection, anemia, using progesterone, paternal alcohol intake, and topography of living areas were associated with a higher risk of severe microtia. All the significant variables were combined into a predictive nomogram (C-index = 0.755,95% CI = 0.703-0.807). Higher prediction accuracy (adjusted C-index = 0.749) was further verified via bootstrap validation. The calibration plot showed good performance, and the ROCs curve analysis demonstrated high sensitivity and specificity. CONCLUSIONS Most microtia patients are male, sporadic, and accompanied by other malformations, which are similar to the phenotypic analysis results of other studies. A nomogram predicting severe microtia was constructed to provide scientific guidance for individualized prevention in clinical practice.

Abstract
OBJECTIVE To depict various temporal bone abnormalities on high-resolution computed tomography in congenital aural atresia patients, and correlate these findings with auditory function test results and microtia subgroup. METHODS Forty patients (56 ears) with congenital malformation of the auricle and/or external auditory canal were evaluated. Auricles were graded according to Marx's classification, divided into subgroups of minor (grades I and II) and major (III and IV) microtia. Other associated anomalies of the external auditory canal, tympanic cavity, ossicular status, oval and round windows, facial nerve, and inner ear were evaluated. RESULTS Minor and major microtia were observed in 53.6 and 46.4 per cent of ears respectively. Mean hearing levels were 62.47 and 62.37 dB respectively (p = 0.98). The malleus was the most commonly dysplastic ossicle (73.3 vs 80.8 per cent of ears respectively, p = 0.53). Facial nerve (mastoid segment) abnormalities were associated (p = 0.04) with microtia subgroup (80 vs 100 per cent in minor vs major subgroups). CONCLUSION Microtia grade was not significantly associated with mean hearing levels or other ear malformations, except for external auditory canal and facial nerve (mastoid segment) anomalies. High-resolution computed tomography is essential in congenital aural atresia, before management strategy is decided.

Moxham LMR, Chadha NK, Courtemanche DJ. Is there a role for computed tomography scanning in microtia with complete aural atresia to rule out cholesteatoma? Int J Pediatr Otorhinolaryngol 2019; 126:109610.

Abstract
OBJECTIVE To determine if radiologic imaging is necessary to rule out cholesteatoma in patients with congenital aural atresia. METHODS A retrospective chart review of patients attending the BC Children's Hospital Microtia Clinic from January 1, 1990 through April 17, 2017 was undertaken. Patients with complete atresia of the external canal were included in the study. Available radiologic imaging and clinical records were examined for the presence or absence of cholesteatoma. RESULTS Of the 125 charts reviewed, 102 met criteria for inclusion in the study and 79 had three-dimensional imaging completed. None of these 102 patients had radiologic or clinical evidence of cholesteatoma. CONCLUSION Computed tomography and/or magnetic resonance imaging remains an essential modality in the work-up of selected patients with microtia/atresia. It may be unnecessary in the follow-up of certain patients to rule out a congenital cholesteatoma. This imaging avoidance may reduce exposure to radiation, the potential need for general anaesthesia, and unnecessary financial cost.

Abstract
Aural atresia is a rare congenital malformation of the external and middle ear. There are several syndromic associations of this anomaly with those involving the first and second branchial arches. Occurrence of aural atresia with sclerosing skeletal dysplasia is unknown and has never been reported. The co-existence of a sclerosing dysplasia can make the surgical treatment in aural atresia difficult and risky; and the auditory improvement may not be as expected. Moreover, internal auditory canal narrowing and hence sensorineural hearing loss in sclerosing dysplasia might add to the already existing conductive hearing loss in such patients. In this case report we have described an unknown association of bilateral microtia with sclerosing skeletal dysplasia (autosomal dominant osteopetrosis) and clinical implications of these two conditions occurring together leading to a change in the management plan.

Abstract
Isotretinoin is a drug used for treating severe cystic/nodular acne. Severe malformations have been documented in neonates whose mothers had taken isotretinoin during pregnancy. Women who became pregnant one cycle after completing therapy are believed to be at teratogenic risk not higher than baseline. We describe the case of a newborn whose mother had taken the drug for 4 weeks. The woman then had contraception for 4 weeks (after the drug treatment had finished), and became pregnant after that period. The newborn had isolated bilateral microtia due to suspected isotretinoin exposure. His mother also had a history of urine tract infection in the second week of pregnancy that was treated with cephalexin. The parents were not from a consanguineous marriage and had no family history of congenital malformations. To reduce the risk, effective contraception should be continued in fertile women more than 1 month after completing therapy.
