Sonographically Guided Core Biopsy of A Parotid Mass

Abstract

Sonographically guided core biopsy is a highly accurate technique for evaluation of parotid lesions and can be safely performed as an outpatient procedure. Sonographically guided core biopsy has potential advantages over fine-needle aspiration cytologic examination, particularly in the typing and grading of lymphoma and carcinoma and in improved differentiation of reactive nodal hyperplasia from lymphoma. The use of sonographically guided core biopsy may help reduce the need for surgical biopsy and facilitates prompt referral to the appropriate clinical team.

Role of Fine-Needle Aspiration Biopsy in the Management of Salivary Gland Masses

“…Increased risks related to bleeding, facial nerve injury, and tumor seeding are the main concerns of CNB (29). However, the safety of CNB has been widely accepted (30). Although long-term follow-up results have not yet been published, the effect of CNB in the preoperative diagnosis of salivary gland masses seems promising.…”

Comparison of Fine-Needle Aspiration and Core Needle Biopsy under Ultrasonographic Guidance for Detecting Malignancy and for the Tissue-Specific Diagnosis of Salivary Gland Tumors

“…The retromandibular vein and external carotid artery are the major intraparotid vessels that are well-visualized with US imaging and can be easily avoided. 22 However, the facial nerve is not readily identified with US. 22,23 It has been suggested in previous reports that USFNA carries a lower risk of complications than USCNB.…”

“…22 However, the facial nerve is not readily identified with US. 22,23 It has been suggested in previous reports that USFNA carries a lower risk of complications than USCNB. 13,24,25 In our current investigation, which included 282 patients who underwent USCNB, there were no major complications observed such as facial nerve injury.…”

Core-needly biopsy of parotid gland masses

“…Precizna dijagnostika uz što manje narušavanje tkiva neophodna je jer za mnoga neneoplastična i neoplastična oboljenja (kao sto sulimfomi) hirurško lečenje nije metod izbora. Takođe, kod benignih lezija, kao što je Vartinov tumor, moguće je nakon precizne histopatološke verifikacije učiniti najmanje invazivno hirurško odstranjivanjeekstrakapsularnu disekciju 7 . Najmanje invazivna metoda za dobijanje biopsionog materijala je aspiracija tankom iglom (FNa, fine-needle aspiration), ali je zbog značajnog broja uzoraka neadekvatnih za patohistološku obradu ova metoda nedovoljno precizna i često su potrebna dopunska ispitivanja-citofluometrija, imunohistohemija, ekstirpaciona biopsija 8 .…”
