Biopsy and removal of mucosal lesions | Dr. Arnaud

Oral surgery encompasses a variety of procedures to diagnose and treat abnormalities in the oral cavity. Among these procedures, biopsies and lesion removal play a crucial role.

What is the purpose of a biopsy?

A biopsy involves taking a sample of suspect tissue from the mouth for laboratory analysis. This analysis is used to diagnose diseases, determine the nature of lesions (benign or malignant) and plan appropriate treatment.

Biopsies are essential for accurate diagnosis. They help identify conditions such as oral cancers, chronic infections and autoimmune diseases. Early diagnosis enables rapid management and increases the chances of successful treatment.

What lesions may be involved?

Mucoceles:

A mucocele is a benign lesion that forms when the minor salivary glands become obstructed, leading to an accumulation of mucus. It often appears as a small translucent bump inside the mouth.

Papillomas:

A papilloma is a benign tumor caused by the human papillomavirus (HPV). It often appears as a small, white, warty growth. They are often painless, and can be noticed during a simple routine consultation.

Fibroids:

Benign growths of connective tissue that can develop in response to chronic irritation, such as constant rubbing against a tooth or denture.

Lichenoid lesions:

Manifestations of autoimmune diseases often appear as white or red patches on the oral mucosa.

Some asymptomatic lesions may be cancerous or become so. It is essential to link the patient’s lifestyle habits (smoking, alcohol, drugs) to the clinical examination in order to determine a hypothetical diagnosis.

Only a biopsy can provide a definitive diagnosis, enabling the appropriate treatment to be carried out.
