The Systematic Use of Tomography in the Diagnosis of Carcinoma of the Paranasal Sinuses

Perineural Invasion by Squamous‐Cell Carcinoma

“…However, as it was in our cases, without symptoms the sensory examination is fruitless. If the physician suspects perineural invasion, tomography should be used to determine if bone is involved along the course of the suspected nerve trunk 22 . Computerized axial tomography (CAT) scans should be done because they may detect enlargement of soft tissues along the course of the nerve.…”

Cranial Neuropathy as a Presenting Sign of Recurrent Aggressive Skin Cancer

“…Traditional roentgen skull series are of minimal use in the evaluation of perineural spread, because delineation of perineural spread is dependent on expansion of the nerve sufficient to produce adjacent bony erosion. Given this late progression and masking by surrounding or superimposed intact bone, this modality should not be used for assessment of potential perineural spread 19,43 …”

Surgical considerations in malignant neoplasia of nose and paranasal sinuses

“…In such cases a thin facial flap is elevated, leaving behind substantial soft tissues over the maxilla for oncological clearance. Occasionally advanced disease may cause skin ulceration or fistula (Dodd et al 1959). Such cases are technically resectable (Bahadur et al 1984), though the defect needs reconstruction with a forehead or a deltopectoral flap.…”
