Radical Surgery for Ethmoid Cancer

Sinonasal Adenoid Cystic Carcinoma

“…In addition, bony metastases have shown to be more aggressive than pulmonary metastases. 81,82 The local recurrence rate and metastasis rate of SNACC in this study were 34.1% and 30.7%, respectively, for the IPD, similar to prior reports. 33 Local recurrence with metastasis occurred 7.9% of the time, which may increase these numbers comparatively.…”

“…This is likely from variation in signal intensity among the multiple histological types due to differences in cell density and cystic composition. 40 In addition, its propensity for perineural spread necessitates careful imaging of the trigeminal nerve branches, especially in the pterygopalatine fossa, to evaluate for intracranial extension. 40 …”

Adenocarcinoma of Ethmoid: A GETTEC Retrospective Multicenter Study of 418 Cases

“…Different approaches were related, 5,6,9,49–51 i.e., transfacial or mixed craniofacial. Endoscopic approach was reported by Shah et al, 52 but only in specific cases (low‐grade limited adenocarcinoma), and Homer et al 53 reserved this approach for non surgically‐treated lesions.…”

Prognostic factors in sinonasal tumors involving the anterior skull base

“…On the other hand, involvement of an only seeing eye, bilateral orbital apex involvement, optic chiasm involvement, massive bony skull base destruction, massive brain involvement, invasion of the clivus or sella turcica, and tumor extension into the cavernous sinus and carotid artery are considered contraindications for craniofacial surgery for malignant lesions. 15 The intracranial approach through the frontal sinus (transfrontal craniotomy), as classically designed, 16,17 involves a partial or total removal of the anterior and posterior walls of the frontal sinus, with the drawback of risk of osteomyelitis in the case of replacement of a devitalized anterior wall of the sinus. We have modified this technique using an osteoplastic frontal flap that has been used in a variety of pathologic conditions of the frontal sinus to avoid this problem.…”
