The provided UK guideline excerpts do not explicitly specify indications for urgent referral to ENT for a patient presenting with stridor in a primary care setting.

However, the guidelines do outline criteria for referral related to other head and neck symptoms. For adults aged 45 and over with persistent and unexplained hoarseness, a suspected cancer pathway referral for laryngeal cancer should be considered . Other indications for ENT referral, as detailed in the provided context, relate to hearing loss, ear pain, discharge, and abnormal ear appearances, but these are not associated with stridor .
