Summary
Lateral temporal bone resection is a key treatment for advanced peri-auricular squamous cell carcinoma. Careful planning and post-operative radiotherapy improve recurrence-free survival, especially for poorly differentiated tumors.
Area of Science:
- Oncology
- Surgical Oncology
- Dermatology
Background:
- Lateral temporal bone resection is utilized for advanced peri-auricular cutaneous squamous cell carcinomas.
- Evidence regarding optimal staging and adjuvant treatment remains conflicting.
Purpose of the Study:
- To evaluate the outcomes of lateral temporal bone resection for cutaneous squamous cell carcinoma.
- To identify factors associated with recurrence-free survival.
Main Methods:
- Retrospective analysis of 29 patients undergoing lateral temporal bone resection for cutaneous squamous cell carcinoma (2015-2019).
- Inclusion of clinico-radiological data, including imaging (CT, MRI, PET).
Main Results:
- Median patient age was 77 years.
- Imaging showed high accuracy for primary tumor sites but low sensitivity for cervical nodal metastasis.
- Tumor differentiation and post-operative radiotherapy were significantly associated with better recurrence-free survival (p=0.0040 and p=0.0199, respectively).
- Six patients experienced recurrence at a median of 4.8 months.
Conclusions:
- Lateral temporal bone resection for peri-auricular cutaneous squamous cell carcinoma necessitates meticulous surgical planning.
- Clinico-radiological correlation is crucial, particularly for patients with poorly differentiated tumors.
