Recurrent Right-side Bell's Palsy in Association with Neurovascular Cross-compression: A Case Report

Introduction: Bell's palsy is a lower motor neuron (LMN) palsy that affects the facial nerve (CN VII) and causes weakness or paralysis of the facial muscles. It can be associated with various causes, including neurovascular cross-compression (NVCC). This case report highlights the challenges in treating recurrent Bell's palsy caused by NVCC and the need for a multidisciplinary approach. Case report: A 17-year-old girl presented with recurrent right-side Bell's palsy along with NVCC involving the right and left anterior inferior cerebellar artery forming a loop around the VII and VIII cranial nerve complex. Motor Nerve Conduction Studies (NCS) indicated a right-side facial nerve lesion with prolonged distal latency. Discussion: Despite prior physiotherapy sessions, which proved effective, the patient showed no improvement after five sessions, leading to further investigations. This case also underscores the diagnostic and therapeutic complexities associated with NVCC-induced Bell's palsy, which emphasizes the urgency of quick diagnosis and intervention to prevent functional limitations. Conclusion: Continued research and advancements in diagnostic and therapeutic modalities are required for better outcomes and improving the quality of life in such patients, particularly in such cases.
