A specimen mount for small laryngeal biopsies

Area of Science:

• Laryngology
• Surgical Pathology
• Oncology

Background:

• Accurate histologic interpretation of laryngeal biopsies is crucial for diagnosis and treatment planning.
• Tangential sectioning of small laryngeal biopsy specimens often hinders accurate interpretation.
• Tissue curling and suboptimal specimen orientation contribute to sectioning artifacts.

Purpose of the Study:

• To introduce and evaluate a novel biopsy specimen mount for laryngeal biopsies.
• To assess the mount's efficacy in preventing tangential sectioning artifacts.
• To determine the mount's utility in margin assessment for vocal cord lesions.

Main Methods:

• A biopsy specimen mount was utilized for small laryngeal biopsy specimens.
• Histologic sections were analyzed for the presence of tangential cuts.
• The mount's ability to facilitate margin assessment was evaluated.

Main Results:

• The biopsy specimen mount effectively eliminated tangential sectioning of laryngeal biopsy specimens.
• Accurate determination of deep and peripheral margin involvement was achieved.
• The mount proved useful in assessing vocal cord leukoplakia and early glottic malignancy.

Conclusions:

• The biopsy specimen mount is a valuable tool for improving the accuracy of laryngeal biopsy interpretation.
• It facilitates precise margin assessment, aiding in the endoscopic surgical management of vocal cord lesions.
• This method supports individualized and rational therapeutic planning for early glottic cancers.
