“…As a parallelism, one could argue that paralysis of muscle districts responsible for sound production may impact sensory aspects of linguistic processing. A study on people with Moebius syndrome—a congenital neurological disorder causing complete face paralysis which causes impairments in articulating speech sounds ( Pamplona et al, 2020 )—did not find support for the hypothesis that lack of muscle control impacts lip reading, an aspect closer to face-to-face linguistic communication ( Vannuscorps et al, 2021 ). This suggests that it is unlikely that damage to or atypical development of more peripheral mechanisms of speech and language production affects relevant aspects of speech processing.…”

Predictive processing, a crucial aspect of human cognition, is also relevant for language comprehension. In everyday situations, we exploit various sources of information to anticipate and therefore facilitate processing of upcoming linguistic input. In the literature, there are a variety of models that aim at accounting for such ability. One group of models propose a strict relationship between prediction and language production mechanisms. In this review, we first introduce very briefly the concept of predictive processing during language comprehension. Secondly, we focus on models that attribute a prominent role to language production and sensorimotor processing in language prediction (“prediction-by-production” models). Contextually, we provide a summary of studies that investigated the role of speech production and auditory perception on language comprehension/prediction tasks in healthy, typical participants. Then, we provide an overview of the limited existing literature on specific atypical/clinical populations that may represent suitable testing ground for such models–i.e., populations with impaired speech production and auditory perception mechanisms. Ultimately, we suggest a more widely and in-depth testing of prediction-by-production accounts, and the involvement of atypical populations both for model testing and as targets for possible novel speech/language treatment approaches.

“…Physical and speech therapy are needed to improve motor skills, coordination, and better control of speaking and eating abilities. With early speech therapy intervention, similar patients have great improvements in their speech [ 7 ]. Regular dental appointments are also necessary as these patients have difficulty removing food from their teeth and buccal spaces due to impaired jaw mobility, which can lead to poor dental health.…”

“…Early surgical interventions also play a role in treatment. Gracilis muscle-free transfers for the development of smile expression (“smile surgery”) and procedures to correct strabismus and limb and jaw deformities have been reported [ 7 , 3 ]. As previously discussed, the care of this wide array of clinical anomalies requires numerous specialists.…”

Moebius syndrome is a rare congenital disorder characterized by nonprogressive uni- or bilateral abducens nerve (VI) and facial nerve (VII) palsy. Other cranial nerves (CN) such as CN III, IV, and IX-XII may be involved leading to varied presentations. Speech development, communication, and psychomotor complications are common. Given the complexity of the disease, patients require an individualized, multidisciplinary care plan involving many medical specialists. Accessing this level of care without insurance poses seemingly insurmountable challenges and places immense financial strain on both patients with Moebius syndrome and their families. Physicians must advocate for patients with Moebius syndrome and be knowledgeable about the community resources available to them such as non-profit organizations. This report presents a case of Moebius syndrome in an uninsured, immigrant, 13-year-old male and the barriers to providing him with adequate care.

“…Meanwhile, micrognathia could induce cleft palate in turn by impeding tongue development[ 30 , 31 ]. In addition, missing teeth may result in malocclusion, periodontal damage, insufficient alveolar bone growth, reduced chewing ability, inarticulate pronunciation, and other problems[ 32 - 34 ]. As reported in most studies, MBS patients lack of lip seal, which is closely related to the high prevalence of the Class II pattern with micrognathia and excessive maxillary development, attributed to the alteration of the motor and sensitive facial nerves and to the maldevelopment of the brainstem[ 35 - 37 ].…”

BACKGROUND Moebius syndrome (MBS) is a nonprogressive and rare congenital neuromuscular disorder involving the facial nerve and abductor nerve; it mainly manifests as facial paralysis and eye strabismus paralytic symptoms. Tissues in the oral cavity are also compromised, characterized by microstomia, micrognathia, tongue malformation, cleft lip, high arched palate or cleft palate, bifid uvula, and dental malocclusion. Therefore, dentistry plays a fundamental and crucial role in caring for these individuals. However, there is limited available data on MBS treatment, particularly regarding dental management. CASE SUMMARY This case report presents dental treatment of a 21-year-old man with MBS and discusses crucial interactions among oral complications of MBS. In this case, the patient was clinically characterized by congenital neuromuscular disorder, occlusal disorders, and tooth and gum problems. It is noteworthy that the patient presented early eruption of deciduous teeth 2 mo after birth, which has not been reported in other MBS cases and suggests a potentially new clinical manifestation of this syndrome. It is important to note that MBS cannot be cured, and oral manifestations of this syndrome can be managed by a multidisciplinary health care team that helps the patient maintain oral hygiene and dental health. After a series of oral treatments, no obvious poor oral hygiene, swollen gums, or abnormal imaging results were observed after 2 years of follow-up. CONCLUSION This case addressed the oral clinical manifestations of MBS and difficulties experienced during dental management, and suggested early tooth eruption as a potentially new clinical manifestation of this syndrome. Knowledge of the loop-mediated association among oral complications of this syndrome is essential to perfecting treatments.
