The dataset has been developed for the reporting of resection and biopsy specimens of the ear and temporal bone. It includes only primary tumours of the external auditory canal, middle and inner ear, including both benign and malignant entities (specifically due to anatomic confines and management alternatives which may require significant, destructive or disfiguring surgery).
By definition, all malignancies of the external ear (pinna, concha, scaphoid, lobe, etc., such as squamous cell carcinoma (SCC), basal cell carcinoma, pleomorphic dermal sarcoma, Merkel cell carcinoma and melanoma) are separately covered by the ICCR Skin Datasets. Primary parotid gland malignancies with direct extension in to the ear canal are excluded; the ICCR Carcinomas of the major salivary glands dataset should be used. Haematolymphoid neoplasms are also excluded from this dataset.
Neck dissections and nodal excisions are dealt with in a separate dataset, and this dataset should be used in conjunction, where applicable.
For bilateral tumours, a separate dataset should be completed for each tumour.
This dataset is intended for use for primary tumour resections. For resections of recurrent disease, the reporting guide may be used pragmatically although some data elements may be not applicable nor assessable.
