Abstract:
Developmental lesions, including benign or malignant tumors, rarely arise in the masseteric region. This retrospective study was performed to evaluate the adequacy of different surgical approaches in a series of patients with lesions in the masseteric region. The surgical methods, postoperative complications, pathological diagnosis, and aesthetic outcome were compared in 4 patients who underwent excision of intramasseteric mass lesions. A flap was elevated in 3 patients and direct incisional resection was performed in 1 patient. Two patients underwent incisional biopsy to exclude malignancy before the total excision was performed. The final diagnosis was hemangioma in 3 patients and schwannoma in 1 patient. All patients were satisfied with the aesthetic results and there were no major complications. In conclusion, surgery with skin flap elevation was concluded to be the best approach based on overall assessment of technical considerations, complications, and the cosmetic outcome. However, the surgeon should not hesitate to perform direct incisional biopsy when malignancy needs to be excluded.

Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...
