Orbital exenteration: Symptoms, indications, tumour localizations, pathologies, reconstruction, complications and survival

Orbital Exenteration in Recurrence Cancer: 5 Years Experience

INTRODUCTION

The purpose of this study was to assess the overall survival (OS) and disease-free survival (DFS) of patients who underwent orbital exenteration for periorbital, conjunctival, and primary intraorbital carcinomas. Additionally, we assessed the outcomes of anterior retrograde temporalis muscle flap restoration.

METHODS

For all patients who had orbital exenteration in the previous five years, a non-comparative retrospective assessment of their medical records, histology, and radiographic imaging was carried out. We investigated the relationships between the various qualitative factors using Cramer's V Kaplan-Meier (KM) analysis. For each of the patient's categorical factors that were of relevance, estimates of the survival distribution were displayed, and log-rank tests were used to determine whether the survival distributions were equal.

RESULTS

This study looks at 19 participants. The sample is made up of 13 men (68%) and 6 women (32%). The degree of relationship (Cramer's V index) between lymph node metastases (N) and the existence of distant metastases (M) is high, at 64%, and is statistically significant because the p-value is 0.0034 < 0.005. Lymph node metastases had a statistically significant impact on overall survival (p = 0.04 < 0.05). Thirteen of the nineteen patients tested had no palsy (68%). There was no one presenting a CSF leak.

CONCLUSION

Our findings show how crucial it is to identify any lymph node involvement that orbital neoplasms may have. In patients who have received many treatments, sentinel lymph node biopsy (SLNB) may be used to determine the stage and spread of the cancer. To determine whether additional tumor characteristics may be explored, more expertise in the SLNB field for patients with orbital cancer who have received many treatments may be helpful. To prevent additional scarring and to be comparable to previous techniques for facial nerve lesions, the anterior retrograde approach and the transorbital procedure for temporal muscle flap in-setting are both effective methods.

Clinicopathological features of patients with wide local excision of eyelid malignant neoplasms: a more than five years retrospective study from China

Background

To investigate the correlation between the clinical and pathological characteristics and outcomes in patients with eyelid malignant tumors underwent wide local excision.

Methods

This retrospective study included 141 cases of eyelid malignant neoplasms from January 2010 to December 2015 in Shanxi eye hospital. Demographic and clinical information were collected. The Kaplan–Meier method was used to calculate survival curves, and the log-rank test method was used to compare survival between groups. Cox proportional regression models were used to calculate the hazard ratios (HR) of total recurrence rate and metastasis rate.

Results

Overall, there were 141 eyelid malignant neoplasms cases aged 65.34 ± 9.69 (range, 41—88) years old. The duration time range was from 1 to 828 (61.09 ± 122.21) months. Basal cell carcinoma (BCC) is the most common of all eyelid malignancies, accounting for 84 (59.5%), followed by Sebaceous gland carcinoma (SGC, 41, 29%), Squamous Cell Carcinoma (SCC, 11, 7.8%), Malignant Melanoma (MM, 3, 2.1%)。On cox-regression analysis, pathological classification (HR 1.959; 95% CI 1.012–3.790; p = 0.046) and eyelid tumor surgery history (HR 17.168; 95% CI 1.889–156.011; p = 0.012) were independently associated with recurrence in patients with eyelid malignant neoplasm. Pathological classification (HR 2.177; 95% CI 1.423 -3.331; p < 0.001) was independently associated with metastasis in patients with eyelid malignant neoplasm. Recurrence and metastasis were most likely to occur in 3 years after surgery.

Conclusion

Wide local excision is an effective and economical treatment for eyelid malignant neoplasms. The prognosis is mainly related to pathological types, eyelid tumor surgical history and TNM stages.

Endoscopic-assisted orbital exenteration: Technical feasibility and surgical results from a single-center consecutive series

The purposes of this study were to describe the endoscopic-assisted orbital exenteration surgical techniques, to report preliminary outcomes and to discuss advantages, indications and limitations of this approach. All patients who underwent endoscopic-assisted orbital exenteration at a single tertiary-care center were retrospectively reviewed. A concomitant reconstruction was performed in all cases. The extent of surgical resection was tailored to the size and location of tumor and was classified into four subtypes. A total of 40 patients were included in this series. Orbital exenteration type 1 was performed in 7 cases, type 2 in 11 cases, type 3 in 19 cases, and type 4 in 3 cases. The reconstruction was performed with a pedicled temporal flap in 5 patients and with a free vascularized flap in 34 cases. A radical resection of disease was obtained in 32 cases. After a mean follow-up of 36 months, 14 patients died of disease, one patient died of other causes, 7 are alive with disease, and 18 patients are currently alive without evidence of disease. The preliminary data emerging from this case-series support the feasibility and safety of endoscopic-assisted orbital exenteration.
