The Canadian Association of Radiologists (CAR) Head and Neck Expert Panel consists of radiologists, a laryngologist and laryngeal surgeon, a patient advisor, and an epidemiologist/guideline methodologist. After developing a list of 11 clinical/diagnostic scenarios, a systematic rapid scoping review was undertaken to identify systematically produced referral guidelines that provide recommendations for one or more of these clinical/diagnostic scenarios. Recommendations from 17 guidelines and contextualization criteria in the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) for guidelines framework were used to develop 26 recommendation statements across the 11 scenarios. This guideline presents the methods of development and the referral recommendations for sinus disease, tinnitus, thyroid and parathyroid disease, neck mass of unknown origin, acute sialadenitis, chronic salivary conditions, and temporomandibular joint dysfunction.

Postoperative radioactive iodine (RAI) administration is widely utilized in patients with differentiated thyroid cancer. While beneficial in select patients, it is critical to recognize the potential negative sequelae of this treatment. The prevention, diagnosis, and management of the salivary and lacrimal complications of RAI exposure are addressed in this consensus statement.
A multidisciplinary panel of experts was convened under the auspices of the American Head and Neck Society Endocrine Surgery and Salivary Gland Sections. Following a comprehensive literature review to assess the current best evidence, this group developed six relevant consensus recommendations.
Consensus recommendations on RAI were made in the areas of patient assessment, optimal utilization, complication prevention, and complication management.
Salivary and lacrimal complications secondary to RAI exposure are common and need to be weighed when considering its use. The recommendations included in this statement provide direction for approaches to minimize and manage these complications.

Postoperative radiotherapy is the standard of care for resected major salivary cancers that are at risk of locoregional recurrence. Of the various histological subtypes, perineural invasion is most common in adenoidcystic carcinomas of the three major salivary glands - parotid, submandibular and sublingual. The clinical target volume (CTV) for these cases must include the relevant cranial nerve pathways at risk. A contouring atlas was devised for delineation of the CTV of the nerves supplying the major salivary glands.
Using standard anatomy texts and e-anatomy sources the nerves supplying the major salivary glands were identified. Subsequently the pathways of the nerves were drawn on an archived patient\'s planning computed tomography scan.
The innervation of the major salivary glands has been identified and studied. Both bone and soft tissue CTVs have been delineated. A full set of images and CTVs of all the relevant transverse computed tomography slices has been archived, a number of which are printed in this article.
Variation in CTV delineation is a recognised problem in a variety of anatomic sites. Guidelines and atlases can standardise practice and may improve the safety and efficacy of therapy. An atlas has been generated to guide clinicians in delineating the CTVs for perineural spread in major salivary gland cancers.
