En bloc temporal bone resections in squamous cell carcinoma of the ear. Technique, principles, and limits

Acta Otolaryngol. 2016;136(5):425-32. doi: 10.3109/00016489.2015.1126352. Epub 2016 Jan 29.

Abstract

Conclusions: En bloc resection should always be primarily considered in ear carcinoma, also in advanced tumors growing beyond the walls of the external auditory canal, because it achieves a full specimen for histopathological evaluation and allows a correlation between clinical, pathological features, and outcomes.

Objective and methods: Dismal outcome of surgical and radiotherapic therapies for advanced ear carcinoma required a critical discussion of the oncological principles of treatment. Our analysis involved preliminarily a detailed description of surgical technique including the contribution of modern skull base microsurgery.

Results: Evident limits in diagnostic protocols, surgical treatment and outcome evaluation modalities pointed to the need of a new approach towards an accurate definition of pre-operative tumor location, size, and behavior. En bloc resection achieved a specimen for a final pathological evaluation and an adjunctive piecemeal excision was necessary only whenever resection was not felt falling in safe, tumor-free tissue. Chemotherapy and radiotherapy should be considered in selected cases for adjuvant treatment.

Keywords: Temporal bone; en bloc resection; squamous cell carcinoma; surgical technique.
