Characterizing Speech Phenotype in Individuals With Craniofacial Microsomia: A Scoping Review

INTRODUCTION

Craniofacial microsomia (CFM) is a complex congenital condition primarily affecting the ear, mandible, facial nerve and muscles, and tongue. Individuals with CFM are at increased risk of hearing loss, obstructive sleep apnea, and feeding/swallowing difficulties. The purpose of this scoping review was to summarize evidence pertaining to speech production in CFM.

METHOD

All articles reporting any characteristic of speech production in CFM were included and screened by two independent reviewers by title, abstract, and full text. Data charting captured details related to study population and design, CFM diagnostic criteria, speech outcome measurement, and key findings. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews checklist guided reporting of results. Our protocol was registered on the Open Science Framework (https://osf.io/npr94/) and published elsewhere.

RESULTS

Forty-five articles were included in the detailed review. Most articles originated from the United States, were published in the past decade, and utilized case report/series study design. A speech-language pathologist authored 29%. The prevalence of velopharyngeal insufficiency ranged from 19% to 55% among studies. Oral distortion of alveolar and palatal fricatives and affricates primarily characterized articulation errors. Studies identified increased disordered speech and lower intelligibility in adolescents with CFM compared to unaffected peers. Evidence pertaining to phonatory and respiratory speech findings is limited.

CONCLUSIONS

Evidence supports that individuals with CFM are at increased risk of both velopharyngeal and articulatory speech differences. Additional information is needed to develop speech screening guidelines for children with CFM. Heterogeneity in study design and outcome measurement precludes comparisons across studies.

Congenital abnormalities associated with microtia: A 10-YEARS retrospective study

OBJECTIVE

Microtia is a congenital auricular malformation, often part of a syndromic form (35%-55% of cases). The accurate prevalence of associated malformations remains to be determined with regard to the heterogeneous results of the previous studies. This study aims to describe in a large population cohort the abnormalities associated with microtia and to determine the most suitable assessment for these children.

METHODS

This is a retrospective and observational cohort study collecting data from the medical records of children affected by microtia, diagnosed or followed-up between 2007 and 2017. Data were collected via a computer database. Clinical data, as well as imaging or genetic results, were noted.

RESULTS

Six hundred ninety four children were included, 587 (84.6%) with unilateral and 107 (15.4%) with bilateral microtia. Inner ear malformations were observed in 14.1% of the ears. The main associated anomalies were hemifacial microsomia (29%), velopharyngeal insufficiency (9%), ophthalmologic (6.2%), vertebral (5.9%), cardiac (5.5%) and kidney (3%) abnormalities. Main identified entities were Goldenhar, Treacher-Collins and Guion-Almeida syndromes.

CONCLUSION

A comprehensive clinical assessment must be completed when microtia is diagnosed. Besides screening well-known oculo-auriculo-vertebral spectrum malformations, velopharyngeal insufficiency should be systematically sought. Specialized care must be provided to the very frequently associated hemifacial macrosomia. Mild forms of this last malformation may correspond to Guion-Almeida syndrome, especially in cases of learning disability.

Auricular reconstruction

External ear abnormalities are common. These may affect ear shape, size, prominence and degree of development. They may also be associated with hearing loss. The early identification and management of hearing loss is essential. There are several options for reconstruction of the external ear using both autologous and non-autologous techniques. The aim of this article is to outline the different reconstructive options.
