Recommended treatment is C0-C2 fusion which, however, will result in significant loss of mobility in the craniocervical junction (CCJ), especially C1-C2 rotation. An alternative approach, with the ability of preserving mobility in the C1-C2 segment, is a temporary fixation that allows the ligaments to heal, after which the implants can be removed to regain function in the CCJ joints. By using a muscle-preserving approach and navigation for the C2 screws, a relatively atraumatic fixation of the CCJ can be achieved with motion recovery after implant removal. <b>Results</b>  We present two cases of AOD treated with temporary fixation. A 12-year-old boy involved in a frontal car collision, as a strapped back seat passenger, was treated with temporary C0-C2 fixation for 10 months. Follow-up at 11 months after implant removal included clinical evaluation, computed tomography, magnetic resonance imaging (MRI), and flexion-extension X-rays. He was free of symptoms at follow-up. The CCJ was radiographically stable and he had 45 degrees of C1-C2 rotation. A 7-year-old girl was hit by a car as she got off a bus. She was treated with temporary fixation for 4 months after which the implant was removed. Follow-up at 8 years included clinical evaluation and MRI in rotation. She was free of symptoms. The ligaments of the CCJ appeared normal and her C1-C2 rotation was 30 degrees. <b>Conclusion</b>  C0-C2 fixation without fusion allows the CCJ ligaments to heal in pediatric AOD. By removing the implants after ligament healing, rotation in the C1-C2 segment can be regained without subsequent instability. Both our patients tolerated the treatment well and were free of symptoms at follow-up. By using minimally invasive muscle-preserving technique and navigation, temporary fixation of the CCJ can be achieved with minimal damage to the soft tissues allowing recovery of almost normal function after implant removal.</p>","PeriodicalId":44256,"journal":{"name":"Journal of Neurological Surgery Reports","volume":"84 1","pages":"e11-e16"},"PeriodicalIF":0.5,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/5f/eb/10-1055-s-0043-1760830.PMC9873479.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9182139","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although it can occur in any portion of the nerve, it predominantly appears near the geniculate ganglion.

Magnetic resonance showed a 5 mm lesion in the lateral portion of the right internal auditory canal. Due to facial palsy, the patient was submitted to a translabyrinthine approach and a total tumor resection, followed by hypoglossal-facial nerve anastomosis. <b>Discussion</b>  The facial nerve is susceptible in its path to expansive lesions, which have high morbidity. FNH is a rare and difficult-to-diagnose lesion. Computerized tomography and nuclear magnetic resonance can be used in its diagnosis. The differential diagnosis of FNH includes, in addition to schwannomas, meningiomas, cholesteatomas, paragangliomas, and other temporal bone tumors. There is no well-established consensus on the best approach. Because of its slow growth and benign behavior, some studies suggest conservative treatment and serial imaging. However, surgery is the cornerstone of treatment, as it is the only curative option. <b>Conclusion</b>  FNHs are often small but very symptomatic.
