Oral Cavity

Oral Cavity

The oral cavity, or the mouth, is a complex structure in humans that plays a vital role in our day-to-day lives. Its role is not only in chewing and swallowing food; it also plays a role in speech and facial expressions.
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...

Area of Science:

Vascular Surgery
Head and Neck Oncology
Pathology

Background:

Hemangiomas are common benign congenital vascular tumors in the head and neck.
Cavernous hemangiomas typically occur on the nasal lateral wall or inferior turbinate.
These lesions can lead to facial deformities despite indolent growth.

Observation:

A 67-year-old woman presented with a cavernous hemangioma in an unusual location: the left retromaxillary masticatory space.
The lesion was surgically excised using the Caldwell-Luc approach.
Post-operative examination confirmed the diagnosis.

Findings:

Anatomopathological and immunohistochemical analyses revealed a malformative vascular lesion.
The findings were consistent with a cavernous hemangioma.
No signs of malignancy were detected.

Implications:

This case highlights the importance of considering rare locations for cavernous hemangiomas.
Successful surgical management via Caldwell-Luc access is demonstrated.
Accurate diagnosis prevents unnecessary aggressive treatment for benign conditions.
