What is segmental resection of mandible?
Segmental resection is indicated in the treatment of benign or malignant mandibular pathology requiring bony margins involving the entire vertical height of the mandible or when a marginal resection would compromise the structural integrity of the mandible.
What is jawbone resection?
Mandibulectomy/Resection of the Jaw. Mandibulectomy A mandibulectomy is a surgery to remove all or part of your jaw. Fibula free flap After part of your jaw is removed, your jaw may be rebuilt using bone from another part of your body, usually your leg.
What is a rim resection?
Mandibular-sparing techniques involving marginal (or rim) resections are appropriate when the tumor invades the periosteum and/or minimally erodes cortical bone. This technique involves resecting a portion of the lingual cortex as part of the surgical margin.
What is RIM Mandibulectomy?
Rim mandibulectomy, because it is based on sound pathologic principles and does not disrupt the mandibular arch, is an operation that adequately resects the tumor without compromising the cancer operation or the patient.
What is partial resection?
A partial hepatectomy, or liver resection, is a type of surgery designed to remove cancerous tumors from the liver. Because this organ has the remarkable capacity to regenerate itself, it can sometimes restore its mass to compensate for tissue lost through surgery.
Why is Hemimandibulectomy done?
Hemimandibulectomy is a complex operation, performed for diseases of the lower jaw (mandible), which include: Tumours – The procedure is usually performed on malignant growths involving either the alveolar ridge and the mandible, or adjacent structures, including the floor of the mouth.
What is composite resection?
A composite resection is the removal of part of the lining of the mouth and lower jaw. This operation is needed when a cancer has grown through the lining of the mouth into to the jaw bone underneath.
What does segmental resection mean in medical terms?
(seg-MEN-tul ree-SEK-shun) Surgery to remove part of an organ or gland. It may also be used to remove a tumor and normal tissue around it. In lung cancer surgery, segmental resection refers to removing a section of a lobe of the lung. Also called segmentectomy.
What is segmental lobectomy?
Segmentectomy and wedge resection surgery are treatments to remove cancer from the lung. These types of surgeries remove only the lung mass and a small portion of the lung along with it, whereas other surgeries, like a lobectomy, remove one or more lobes of the lung.

How long does a segmental Mandibulectomy take?
Your head and neck surgeon will remove the tumor from your jaw and the soft tissue around it. At the same time, your plastic surgeon will remove the bone, tissue, and skin from your donor site. This will take 3 to 4 hours.
What is composite resection of oral cavity?
Why is retromolar Trigone important?
The mucosa covering the Retromolar Trigone is rigid as it is tightly adherent to the underlying alveolar bone. This is what is said to help malignant tumors infiltrate the mandible in a short period if time in the early stages. The rTR is known as the anatomic crossroad where muscular and nervous components converge.
