Abstract
ObjectiveStylohyoid syndrome diagnosis is still challenging nowadays and its symptoms can be easily confused with other orofacial pathologies. The aim of this study is to report a case with stylohyoid syndrome, highlighting the symptoms, diagnosis, and surgical treatment, and describing an unusual major complication. Methods: A 48-year-old woman presented to Portuguese orofacial pain department with a history of progressive and unspecified neck pain lasting for 6 years. After clinical investigation, a stylohyoid syndrome was diagnosed based on previous computed tomography (CT) imaging demonstrating progressive calcification of the stylohyoid complex. Results: Surgery by external approach solved the patient's symptoms, but a transient bilateral hypoglossal palsy was found. It was managed conservatively and recovered within 6 weeks. Conclusion: From our knowledge, this is the first study documenting a stylohyoid complex calcification, improving our knowledge about the calcification progression. Depending on surgical and anatomical conditions, the surgeon should consider approaching the contralateral side in a second surgery to avoid major bilateral complications of the parapharyngeal space, like bilateral hypoglossal palsy.
