Psychosocial and Health-Related Experiences of Individuals With Microtia and Craniofacial Microsomia and Their Families: Narrative Review Over 2 Decades

This paper describes 20 years of microtia and craniofacial microsomia (CFM) psychosocial and healthcare studies and suggests directions for clinical care and research.

A narrative review of papers January 2000 to July 2021 related to psychosocial and healthcare experiences of individuals with microtia and CFM and their families.

Studies (N = 64) were mainly cross-sectional (69%), included a range of standardized measures (64%), and were with European (31%), American (27%), or multinational (23%) samples. Data were generally collected from both patients and caregivers (38%) or patient self-report (35%). Sample sizes were 11 to 25 (21%), 26 to 50 (19%), 51 to 100 (22%), or over 100 (38%). Studies addressed 5 primary topics: (1) Healthcare Experiences, including Medical Care, Hearing Loss/Amplification, Diagnostic Experiences, and Information Preferences; (2) Psychosocial Experiences, including Teasing, Behavioral Adjustment, Psychosocial Support, and Public Perception; (3) Neurocognitive Functioning and Academic Assistance; (4) Pre- and Post-Operative Psychosocial Outcomes of Ear Reconstruction/Canaloplasty; and (5) Quality of Life and Patient Satisfaction.

Care involved multiple specialties and was often experienced as stressful starting at diagnosis. Psychosocial and neurocognitive functioning were generally in the average range, with possible risk for social and language concerns. Coping and resiliency were described into adulthood. Satisfaction and positive benefit of ear reconstruction/canaloplasty were high. Care recommendations include increasing: hearing amplification use, microtia and CFM knowledge among providers, efficient treatment coordination, psychosocial support, academic assistance, and advances to minimize surgical scarring. This broad literature overview informs clinical practice and research to improve psychosocial outcomes.

Correlation Between Mandible and External Ear in Patients with Treacher-Collins Syndrome

BACKGROUND

Patients with Treacher-Collins syndrome (TCS) are frequently affected by congenital ear deformities. The external ear in patients with TCS tends to have both abnormal morphology and reduced overall volume. Previous studies considered a correlation exists between TCS mandibular skeletal features and external ear volume. The purpose of this study was to assess the external ear volume in patients with TCS 3-dimensionally. Furthermore, this study evaluated the relationship between mandibular morphology, external ear profile, and external ear volume.

METHODS

A total of 36 nonoperated patients with TCS were compared to 39 age- and gender-matched normal controls. Morphologic variables of the mandible and the external ear were compared between TCS group and controls by 3-dimensional cephalometrics. The external ear volume and morphologic variables were analyzed with independent sample T-tests and Pearson correlation coefficient analyses (level of evidence: level III).

RESULTS

The external ear volume was reduced by approximately 50% in patients with TCS compared to controls (P < 0.001). External ear length and width were positively correlated with external ear volume (length: r = 0.809, P < 0.001 on left and r = 0.732, P < 0.001 on right; width: r = 0.518, P = 0.001 on left and r = 0.447, P < 0.010 on right). A negative correlation of right ear inclination angle and external ear volume was shown in patients with TCS (r = -0.396, P = 0.027). However, no correlation was shown for the mandibular anatomic variables.

CONCLUSIONS

Three-dimensional analysis confirmed that external ear volume is significantly reduced in patients with TCS. The external ear dimensions and orientation correlated significantly with ear volume. There was no intrinsic association between the severity of mandibular deformity and external ear volume.
