Endoscope-assisted resection of nonneoplastic space-occupying lesion in oral and maxillofacial areas

Abstract

Endoscope-assisted oral and maxillofacial surgeries have been applied to the resection of tumors with minimal invasion and good cosmetic outcomes. However, with regard to endoscope-assisted resection of nonneoplastic space-occupying lesion (NSOL) in oral and maxillofacial areas which differ from tumors in treatment, there are no systematic reports. Therefore the advantages and limitations of the endoscopy-assisted approach (EAA) in resection of NSOL remain unclear. In this novel study we describe endoscope technique for resection of NSOL in face and submandibular areas and compare the feasibility and effectiveness of EAA with external approach (EA). Eleven patients underwent EAA and 20 patients underwent EA procedures. The perioperative and postoperative outcomes of the patients were evaluated. The resection of NSOL with EAA was completed successfully with a shorter hospitalization duration, less bleeding, a smaller incison and better satisfaction with appearance than with the EA procedure (P < 0.01). Our study showed that endoscope-assisted resection of NSOL is technically safe, feasible and practicable. Good cosmetic results with minimal invasion can be achieved with this new technique and therefore this may be a promising new standard procedure in oral and maxillofacial areas.

Gasless Endoscopic Submandibular Gland Excision Through Hairline Approach

“…Regarding SMG excision for benign tumors, the use of retroauricular or hairline approach is recommended only in case of non-large benign tumors, because the removal of large benign SMG tumors by this approach may be associated to the risk of tumor spillage 6 . The most common tumor of the SMG is PA; a pseudocapsule is usually formed around the adenoma in the normal tissue due to the slow compression of expanding tumor to the circumferential tissue of the gland 24 . To avoid intraoperative tumor rupture and spreading of tumor cells in normal tissues, which increase the risk of recurrence of PA, an avascular plane rounding the pseudocapsule should be well located as well as the SMG capsule, and an extracapsular (exocapsular) dissection (between the capsule and the circumferential tissue under magnification of the endoscope) should be achieved for complete removal of SMG and tumor, as well as satellite nodules and pseudopodia of the tumor 4,5,24 …”

Endoscopic-assisted resection of pleomorphic adenoma in the accessory parotid gland

“…Endoscopes are also useful for education (21). However, because of the poor operation space, endoscopic-assisted partial resection around the extracapsular tissue requires a highly skilled technique, which prevents its popularization (22). It is important to use endoscopes frequently to train surgeons.…”

Endoscope-Assisted Hairline Approach for Head and Neck Masses: A Review

“…Head and neck masses are typically identified through physical examination. Given the complex anatomical structures and important functions associated with the head and neck region, it is essential to preserve both the morphology and function in optimizing the effectiveness of surgical treatment [37][38][39]. Branchial cleft cyst presents as a unilateral swelling of the soft tissue, located on the lateral aspect of the neck and anterior to the SCM muscle.…”
