| Popis: | OBJECTIVE: To present a case of a patient with visible stapedius contraction on vocalization and to discuss the related literature. PATIENTS: A 51 year-old woman with a Type III myringostapediopexy due to chronic suppurative otitis media and an incidental finding of voice-induced movement of the stapes head. INTERVENTIONS: Otoendoscopy, pure tone and impedance audiometry, and modified stapedius reflex decay. MAIN OUTCOME MEASURE: Stapes head movement on otoendoscopy. RESULTS: Stapes head movement was seen endoscopically on vocalization but not on tympanometric measures. CONCLUSION: Visible stapedius contraction with vocalization is an uncommon phenomenon. Our understanding of the nonauditory pathways to stapedius is limited and requires further research. |
