Skin malignancies are typically localised in areas of the head that are exposed to the sun. Basal cell carcinomas (BCC) are the most frequent malignancies on the facial skin. Their incidence is raising – due to demographic changes. As regards strategies for resection and reconstruction, the eyelids and the periorbital region are extremely complex and have to be treated in an interdisciplinary context. The aim of the present investigation was to analyse the results of interdisciplinary treatment of periorbital and eyelid non-melanotic malignoma.
All treated non-melanotic malignancies of the eyelid/periorbital region were analysed in a pilot study from September 2017 until July 2019. Patients were treated by an ophthalmologist and a maxillofacial plastic surgeon. The clinical and pathological parameters were collected in a databank. In all interdisciplinary cases, the tumour localisation, histology, R-status and the reconstructive strategy were analysed.
Out of 349 patients, 14 were analysed as they were treated with an interdisciplinary approach. The youngest was 12, the oldest 98 years old. There were 6 women (average age 80.3 years) and 8 men (average age 65.3 years). BCC (n = 10) were the most frequent malignancy; 3 patients suffered from squamous cell carcinoma. Actinic keratosis was diagnosed in one case. In all patients, complete resection (R0) was certified by histopathological examination. The reconstruction was performed immediately in 6 cases, and the reconstruction strategy was accomplished after definitive histology (at least two step procedures) in 8 cases. Only one patient had three resections before starting the reconstruction procedure.
Surgical treatment of malignancies of the eyelid or periorbital non-melanotic malignancies can be an interdisciplinary challenge. BCC is the most frequent entity. These critically localised BCC present with extremely deep infiltration, followed by subtotal or total eyelid resection, often including bony structures. The reconstruction is extremely complex in such cases and requires the whole plastic reconstructive repertoire of both medical disciplines.
