Lateral approach is a more aesthetical option for radical resection of BSCC: assessment of its surgical, oncological, functional, and aesthetic outcomes.

BACKGROUND: The purpose of this study was to introduce a modified lateral approach for combined radical resection of buccal squamous cell carcinoma (BSCC) and evaluate its surgical, oncological, functional, and aesthetic outcomes in comparison with the conventional lower-lip splitting approach. METHODS: This single-center study retrospectively reviewed 80 patients with BSCC, of which 37 underwent the lateral approach and 43 underwent the conventional approach. Surgical, functional, oncological, and aesthetic evaluations, as well as follow-ups, were recorded and compared. RESULTS: Compared to the conventional approach group, the lateral approach group had a longer surgical time (P = 0.000), but there was no significant difference in other surgical and oncological parameters. Moreover, the scar in the head and neck had a significantly discreet appearance in the lateral approach group, whose satisfaction was better than those in the conventional approach group (P = 0.000). Other oral function parameters, postoperative mouth-opening, and 3-year survival rate were not significantly different between the two groups. CONCLUSION: The lateral approach could provide superior aesthetic results while maintaining equal surgical, functional, and oncological outcomes compared to the conventional approach for radical resection of BSCC.

5-aminolevulinic acid photodynamic therapy for extensive oral leukoplakia with concomitant oral submucous fibrosis: A case report.

BACKGROUND: Oral leukoplakia and oral submucous fibrosis are potentially malignant disorders of the oral cavity, with high rates of recurrence and malignant transformation. Notably, the malignant transformation rate of oral leukoplakia with concomitant oral submucous fibrosis is significantly higher than that of oral submucous fibrosis or oral leukoplakia alone. However, the management of these conditions is not well defined. Photodynamic therapy is a minimally invasive treatment modality that effectively targets oral potentially malignant disorders, such as oral leukoplakia, erythroleucoplakia, and verrucous hyperplasia, with the advantages of being repeatable and leaving no scarring. CASE PRESENTATION: We report the case of a 42-year-old man with concomitant oral leukoplakia and oral submucous fibrosis almost involving the entire right buccal mucosa, who underwent six sessions of topical 5-aminolevulinic acid-mediated photodynamic therapy. RESULTS: Photodynamic therapy successfully eradicated whitish plaques and improved mouth opening without any adverse effects. Although photodynamic therapy failed to completely reverse the pathological changes, grading of epithelial dysplasia did not progress and clinical recurrence was not found during the 10-month follow-up. CONCLUSION: In conclusion, topical 5-aminolevulinic acid-mediated photodynamic therapy appears safe and has excellent clinical efficacy against oral leukoplakia-concomitant oral submucous fibrosis, but long-term follow-up is necessary.
