Jaw Tumor
Jaw tumors range from benign odontogenic cysts to aggressive neoplasms. Early diagnosis and appropriate surgical management prevent bone destruction, facial deformity, and — in malignant cases — life-threatening disease progression.
Symptoms to Watch For
Painless Jaw Swelling
A slowly enlarging swelling of the jaw — either upper or lower — that may be noticed on one side of the face. Many jaw tumors are painless in early stages, leading to delayed presentation.
Facial Asymmetry
As a jaw tumor enlarges, it causes visible asymmetry of the face, with one side of the jaw appearing larger, or the chin deviating to one side due to expansile growth.
Loosening of Teeth
Teeth in the area of the tumor may become loose as the supporting bone is eroded or displaced by the growing lesion. This can be mistaken for gum disease.
Bite Change (Malocclusion)
Expansion of the jaw bone by a tumor can alter the alignment of teeth, resulting in a change in how the upper and lower teeth meet when biting.
Numbness of Lip or Chin
Compression or invasion of the inferior alveolar nerve by a mandibular tumor can cause numbness or altered sensation in the lower lip and chin.
Incidental X-ray Finding
Many jaw cysts and tumors are discovered incidentally on dental X-rays (OPG) taken for routine dental care, before any clinical symptoms are apparent.
Common Jaw Tumors and Cysts
Ameloblastoma
The most common benign jaw tumor. Arises from tooth-forming cells (enamel organ). Grows slowly but aggressively, expanding and thinning the jaw bone. Requires surgical resection with adequate margins to prevent recurrence.
Odontogenic Keratocyst (OKC)
A cystic lesion with a high recurrence rate due to its aggressive growth pattern. Lined by a distinctive thin epithelium. May be associated with Gorlin syndrome. Requires careful surgical management.
Dentigerous Cyst
Develops around the crown of an unerupted or impacted tooth, most commonly associated with impacted wisdom teeth or canines. Expands progressively if untreated. Usually managed by enucleation and tooth removal.
Odontogenic Myxoma
A benign but locally aggressive tumor arising from the dental follicle or pulp. Has a gelatinous consistency and infiltrates between bone trabeculae, making complete removal challenging.
Central Giant Cell Granuloma
A benign lesion of the jaw caused by proliferation of giant cells. Can be aggressive or non-aggressive. Treatment ranges from intralesional injections to surgical curettage or resection depending on behavior.
Jaw Osteosarcoma
A malignant bone tumor of the jaw. Less common than ameloblastoma but requires aggressive treatment including wide surgical resection and often chemotherapy or radiotherapy. Requires accurate staging.
Surgical Management
Treatment of jaw tumors is primarily surgical. The extent of surgery depends on the tumor type, size, location, and biological behaviour:
- Enucleation and curettage — removal of cyst lining with curettage of the bone cavity. Suitable for simple cysts with low recurrence risk.
- Marginal resection — removing the tumor with a margin of surrounding bone while preserving jaw continuity. For smaller, peripherally located tumors.
- Segmental resection — removing a complete segment of the jaw for larger or more aggressive tumors. Requires reconstruction.
- Jaw reconstruction — following segmental resection, the jaw is reconstructed using a fibula free flap (microvascular transfer of a segment of the fibula bone with its blood supply) or iliac crest graft, restoring facial form and enabling dental rehabilitation.
