Infant Facial Paralysis Associated with Epstein-Barr Virus Infection

Clinical and Sociodemographic Characteristics of Patients with Peripheral Facial Paralysis in Medical Rehabilitation: A Comprehensive Description

Background and Objectives: Peripheral facial paralysis (PFP) is a condition with diverse etiologies, requiring multidisciplinary management. This study aimed to describe the sociodemographic, clinical, and functional characteristics of patients with PFP treated at the Rehabilitation Service of the University Hospital of Burgos and to evaluate factors associated with the initial degree of impairment. Materials and Methods: A descriptive, cross-sectional study was conducted on 45 patients referred to the Rehabilitation Service from July 2018 to July 2023. Inclusion criteria included first-time rehabilitation visits for PFP during the study period with signed informed consent. Patients with prior PFP on the affected side or severe comorbidities, such as stroke, were excluded. Data were collected from medical records and initial evaluations. The Sunnybrook Facial Grading System (SFGS) was used to assess impairment. Results: Idiopathic paralysis was the most common etiology, with a predominance in men (60.9%) and middle-aged or older adults. Otorhinolaryngology was the leading referral service, though primary care referrals were underrepresented. Delays in initiating rehabilitation were identified, especially in complex cases like acoustic neurinoma. The ANOVA test revealed no significant differences in functional assessments based on age, sex, or etiology, likely due to the limited sample size. Conclusions: The study highlights the predominance of idiopathic etiology in PFP and the importance of otorhinolaryngology in referrals. Greater awareness in primary care and early identification are crucial. Future studies with larger samples are needed to evaluate predictors of impairment and optimize rehabilitation strategies.

Rare Diseases of the Salivary Glands and of Facial Nerve

Salivary gland diseases are rare. In the European Union (EU) a disease is considered to be rare if not more than 5 of 10,000 people are affected by it. According to estimates in Germany are about 4 million people with a rare disease. In the EU are about 30 million people with rare diseases [1]. In the present work most of the described diseases of salivary glands and of the facial nerve fall in this category. They form a very heterogeneous group whose treatment takes place mainly in specialized centers. Still, it is essential for the otolaryngologist to identify and to diagnose these diseases in order to initiate the right therapeutic steps. The work is a compilation of innate andacquired rare salivary gland disorders and of rare facial nerve disorders. The etiologies of inflammatory diseases, autoimmune disorders and tumors are taken into account. For the individual topics, the current literature, if available, was evaluated and turned into summarized facts. In this context the development of new processes, diagnostics, imaging and therapy are considered. Genetic backgrounds of salivary gland tumors and the trends in the treatment of tumorous lesions of the facial nerve are picked up. Furthermore, also rare diseases of the salivary glands in childhood are described. Some of them can occur in adults as well, but differ in frequency and symptoms. Due to the rarity of these diseases, it is recommended to tread these in centers with special expertise for it. Finally, the difficulties of initiation of studies and the problems of establishing disease registries concerning salivary gland disorders are discussed. This is very relevant because these pathologies are comparatively seldom.
