A lesion arising from the deep lobe of the parotid gland may cause postero-medial displacement of the styloid process, resulting in widening of the stylomandibular tunnel. However, a lesion in the carotid space tends to displace the styloid process anteriorly, causing narrowing of the tunnel. \u003c/p\u003e","id":3055,"imageUrl":null,"imageAttribution":null,"imageAttributionCaseInfo":null,"firstQuestionPath":"/questions/3055","nextQuestionPath":null,"relatedArticles":[{"id":1320,"title":"Facial nerve","link":"/articles/facial-nerve?lang=gb"},{"id":46108,"title":"Mylohyoid muscle","link":"/articles/mylohyoid-muscle?lang=gb"},{"id":63090,"title":"Stylomandibular tunnel","link":"/articles/stylomandibular-tunnel?lang=gb"},{"id":10466,"title":"Carotid space","link":"/articles/carotid-space?lang=gb"},{"id":10465,"title":"Parotid space","link":"/articles/parotid-space?lang=gb"},{"id":34675,"title":"Retromandibular vein","link":"/articles/retromandibular-vein?lang=gb"},{"id":54540,"title":"Facial vein","link":"/articles/facial-vein?lang=gb"},{"id":170687,"title":"Parotid gland tumours","link":"/articles/parotid-gland-tumours-1?lang=gb"}],"alsoUsedIn":[{"id":2162,"kind":"Course","title":"2024 Virtual Conference Private Use - page 2162","link":"https://radiopaedia.org/courses/2024-virtual-conference-private-use/pages/2162"}],"stem":"\u003cp\u003eWhich of these structures can help to distinguish between a tumour arising from the deep lobe of the parotid gland and the carotid space? \u003c/p\u003e","menuLinks":[{"text":"Report problem with question","url":"https://docs.google.com/forms/d/e/1FAIpQLSfO3soWYhOjJ7yErSysyCe5V4A1CqW7WK3rDA7MtAkecMGqNw/viewform?entry.1624461248\u0026entry.553583435=https://radiopaedia.org/questions/3055"}],"attemptsPercentages":[{"alternativeId":"14840","percentage":17},{"alternativeId":"14837","percentage":33},{"alternativeId":"14836","percentage":33},{"alternativeId":"14838","percentage":17},{"alternativeId":"14839","percentage":0}],"promptToLogin":false,"questionManager":false,"articleId":"styloid-process"}
