Based on your answers, there are no immediate signs of buccal cancer or acute pathology. Routine screening is advised.
Buccal Mucosa Squamous Cell Carcinoma Protocol
Squamous Cell Carcinoma (SCC) of the buccal mucosa (the inner lining of the cheek) is highly prevalent in South Asia. This malignancy is strongly associated with the habit of chewing and holding betel quid, gutkha, paan, or tobacco in the cheek pouch. These chemical carcinogens induce chronic irritation, leading to precancerous states and eventual malignant transformation.
1. Oral Submucous Fibrosis (OSMF) & Trismus
A significant complication in buccal mucosa cancer is its association with Oral Submucous Fibrosis (OSMF). Caused by betel nut alkaloids, OSMF leads to progressive deposition of dense collagen fibers inside the cheek, resulting in severe trismus (restricted mouth opening). Staging and surgical planning must evaluate both the tumor dimensions and the severity of trismus. Often, a bilateral fibrous band release is executed concurrently with tumor resection to restore adequate mouth opening.
2. Composite Resections & Bone Involvement
The buccal mucosa lies in close proximity to the mandible (lower jaw) and maxilla (upper jaw). Advanced cheek tumors frequently infiltrate the underlying alveolar bone or the masticator space. In such cases, executing a Composite Resection is necessary. This involves removing the primary tumor, a segment of the jaw bone (marginal or segmental mandibulectomy), and the regional lymph nodes in the neck. Achieving clear bone and soft tissue margins microscopically (R0 margins) remains the absolute priority.
3. Neck Dissection Staging
Like other oral cancers, buccal mucosa SCC spreads early to Level I, II, and III neck lymph nodes. Selective neck dissection is performed to clear out these nodes. If the tumor is large (T3/T4) or clinically node-positive, a comprehensive neck dissection is mandatory to control disease progression.
4. Tissue Flap Reconstruction Choices
Reconstructing a cheek defect requires restoring both the inner lining (to prevent scarring and contracture that would worsen trismus) and, in full-thickness defects, the outer facial skin:
- Local / Regional Flaps: Submental flaps or temporalis myofascial flaps are useful for moderate inner lining defects.
- Microvascular Free Flaps:
Radial Forearm Free Flap (RFFF): Thin and extremely pliable, ideal for replacing the inner lining of the cheek to allow smooth jaw movement.
Anterolateral Thigh (ALT) Flap: Providing bulk and thickness, ideal for massive, full-thickness cheek defects (often designed as a folded, bi-paddled flap to reconstruct both the inner cheek liner and external facial skin).
