Preoperative assessment for and outcomes of mandibular conservation surgery

Abstract

Mandibular conservation surgery is oncologically safe for patients with early mandibular invasion. Accurate preoperative assessment that combines clinical examination and radiographic evaluation is better than either modality alone, but clinical judgment is still necessary for proper patient selection.

Retromolar trigone squamous cell carcinoma treated with radiotherapy alone or combined with surgery: a 10-year update

“…The prognoses for SCC of the tonsil, floor of mouth, alveolar ridge, and RMT differ drastically despite each anatomic unit being separated by only millimeters [1][2][3]. Surgery is technically demanding since the tumor has often extended to adjacent sites at the time of diagnosis, and complete removal frequently requires resection and reconstruction of the mandible, oral mucosa, oropharynx and even the maxilla [4][5][6][7][8].…”

Prognostic impact of marginal mandibulectomy in the presence of superficial bone invasion and the nononcologic outcome

“…Few authors have reported adequate tumor control with marginal mandibulectomy for superficial medullary cavity involvement in a limited number of cases. 3,11 In our series, 1 patient with evidence of superficial medullary invasion achieved good tumor control after marginal mandibulectomy and postoperative radiotherapy. Nevertheless, we recommend segmental resection when tumor invades the medullary cavity.…”

“…Although bone invasion is thought to be a poor prognostic factor of tumor control by some, 8,10,11 other authors have varying opinions. 3,4,12 In our series, the local recurrence rate was 14.3% in the mandibular bone invasion group and 22.2% in the no mandibular bone invasion group.…”

“…3 In the literature, the reported rate of patients requiring marginal mandibulectomy for bone invasion varies greatly between 16% and 60%. 4,[10][11][12][13][14] In our case series, the rate of bone invasion (16.3%) was on the lower end of the spectrum. This may be attributed to the detailed preoperative and intraoperative examination.…”
