# Management of Extensive Buccosinusal and Bucconasal Communications After Maxillary Giant Cell Tumor Resection Using the Cortical Bone Lamina Technique: A Case Report

## TL;DR

This case report describes the successful use of the cortical bone lamina technique to manage complex facial defects after removing a maxillary giant cell tumor.

## Contribution

The paper presents a novel application of the cortical bone lamina technique for reconstructing extensive buccosinusal and bucconasal communications.

## Key findings

- The cortical bone lamina technique effectively maintained space and supported bone healing after tumor resection.
- The patient showed favorable outcomes without significant complications following the procedure.

## Abstract

Giant cell tumors are rare, locally aggressive non-odontogenic osteolytic tumors associated with high rates of local recurrence. Treatment modalities are subject to considerable controversy, with successful outcomes hinging on achieving complete tumor elimination through thorough curettage. A 78-year-old male referred in December 2023 for a persistent mucosal lesion in the right maxilla under a removable denture. Clinical examination revealed a well-defined erythematous nodular lesion measuring approximately 3 cm along its long axis, localized on ridge quadrant 1. Biopsy confirmed the diagnosis of giant cell tumor.

Although complete resection with healthy margins may be justified for aggressive lesions, it often results in significant morbidity and requires immediate defect reconstruction. Some studies suggest favorable long-term outcomes with guided bone regeneration (GBR). The bone lamina technique uses a xenogeneic cortical bone membrane to maintain space and promote bone healing. This surgical approach promotes bone healing through the mechanical support and biological properties of the lamina.

The purpose of this case report is to evaluate the efficacy of the bone lamina technique and its role in managing complications following giant cell tumor resection.
