Petrosectomies for invasive tumours: surgery and reconstruction.
Tumours involving the temporal bone have historically carried a bad prognosis. The only prospect of cure is radical en bloc resection. Temporal bone resection for malignancies is, however, such a formidable undertaking that many centres label such tumours as unresectable. Additionally, the enormity of the surgical defect poses a major reconstructive challenge. A review of 14 petrosectomies (in 12 males and 2 females) performed for extensively invasive neoplasms in and around the ear is presented. All underwent immediate reconstruction, the majority (12/14) with free tissue transfers. 9 of the 14 patients (64%) are still alive after a mean follow-up of 70 months (range 4-8 years). With the use of free tissue transfers, an aggressive approach with regard to the resection margins can safely be adopted in the full knowledge that the eventual size of the defect need not compromise tumour clearance. Additionally, free flaps provided a reliable dural seal. This approach of radical en bloc resection with free flap reconstruction has decreased the mortality (compared to the literature), while largely reducing the morbidity to that of unavoidable cranial nerve resection.
