Diagnostic Approach for Left-Sided Head and Neck Pain

Initial Assessment

For a patient with left-sided head and neck pain, the American Academy of Otolaryngology-Head and Neck Surgery recommends identifying red flags such as age >40 years, duration of symptoms ≥2 weeks, and associated symptoms like hoarseness, otalgia, and hearing loss, which increase suspicion for head and neck squamous cell carcinoma 2, 3
The American Academy of Otolaryngology-Head and Neck Surgery suggests assessing risk factors for malignancy, including tobacco and alcohol use, prior head and neck cancer history, and immunocompromised status 3
A thorough physical examination, including palpation of the neck for masses and a complete head and neck examination, is recommended to identify suspicious findings, according to the American Academy of Otolaryngology-Head and Neck Surgery 2, 3

The American College of Radiology recommends contrast-enhanced CT or MRI of the neck for suspected malignancy, based on history and physical exam findings 2, 3
For suspected cervicogenic headache, the American College of Radiology suggests plain radiographs of the cervical spine as first-line imaging, and MRI without contrast if neurological symptoms develop 5, 4
The American Academy of Otolaryngology-Head and Neck Surgery recommends fine needle aspiration (FNA) biopsy if a neck mass is identified and malignancy is suspected 2, 3

The American College of Radiology notes that degenerative changes in the cervical spine are common in asymptomatic individuals over 50 years of age and correlate poorly with symptoms 4
The American College of Radiology recommends reserving MRI for cases with focal neurologic symptoms or pain refractory to conventional treatment, due to its high rate of abnormal findings in asymptomatic individuals 1
