Bone scintigraphy: an aid in deciding on the extent of bone resection in malignant oral tumors.

Purpose: The decision of whether to perform continuity-sparing or resecting surgery of the jaw in cases of malignant oral tumors is often difficult.

Patients And Methods: To aid in this decision, bone scintigraphy was evaluated retrospectively in 304 patients with a squamous cell carcinoma.

Results: One hundred forty-five patients showed no accumulation of the radionuclide, and none of them had infiltration by tumor histologically.

Prognostic significance of DNA ploidy in oral squamous cell carcinomas. A retrospective flow and image cytometric study with comparison of DNA ploidy in excisional biopsy specimens and resection specimens, primary, tumors, and lymph node metastases.

Deoxyribonucleic acid ploidy was determined in paraffin-embedded tumor tissue from 116 patients with primary oral squamous cell carcinomas (including 5 carcinomas of the lip and 14 of the tongue) by means of flow cytometry. One hundred six cases were suitable for evaluation (91%). Sixty-eight percent of the cases (n = 72) showed a nondiploid nuclear DNA content.

[Indications for 76 free surgical flaps for mandibular reconstruction].

Since 1985 76 revascularized osseous and osseocutaneous flaps collected from different donor sites were transferred. The overall rate of success amounted to 94.7%, 48.

A modification of the Sanvenero-Rosselli velopharyngoplasty.

A modification of the cranially-pedicled velopharyngoplasty is described. It consists of the preparation of two mucosal flaps on the dorsal side of the soft palate. They are pedicled on the velar rim and sutured to the free part of the pharyngeal flap between its origin and the recipient bed.
