Cartilage implants: material, (usually from the patient's rib), is implanted to create an anterior projection on the pharyngeal wall. Most of the time, the success rate is low because the surgeons could not get a large enough sample from the ribs to stay in place in the pharyngeal wall. Later, several surgeons only performed this surgery on ...
A CT scan shows a solid mass of Tornwaldt's cyst and MRI shows a glass-shaped lesion with fluid on the upper part of the posterior nasopharyngeal wall. Additionally, a cystic mass in the upper part of the nasopharyngeal wall and mucopurulent discharge from upper part of the mass can be seen on nasal endoscopy. Among them MRI is the best for ...
The danger space serves as an important pathway for complicated infections of the posterior pharynx to enter the chest and spinal column. Anterior to the parapharyngeal space is the masticator space which contains the lower dental row, muscles of mastication, the inferior alveolar nerve as well as branches of cranial nerve V.
The hypopharynx includes the pyriform sinuses, the posterior pharyngeal wall, and the postcricoid area. Tumors of the hypopharynx frequently have an advanced stage at diagnosis and have the most adverse prognoses of pharyngeal tumors. They tend to metastasize early due to the extensive lymphatic network around the larynx. [citation needed]
Oropharyngeal cancer, [1] [2] [3] also known as oropharyngeal squamous cell carcinoma and tonsil cancer, [1] is a disease in which abnormal cells with the potential to both grow locally and spread to other parts of the body are found in the oral cavity, in the tissue of the part of the throat that includes the base of the tongue, the tonsils, the soft palate, and the walls of the pharynx.
The petroclinoid ligament is a fold of dura matter. It extends between the posterior clinoid process and anterior clinoid process and the petrosal part of the temporal bone of the skull. There are two separate bands of the ligament; named the anterior and posterior petroclinoid ligaments respectively.
Nasopharyngeal cyst refers to cystic swelling arising from midline and lateral wall of the nasopharynx. The commonest cyst arising from lateral wall is the nasopharyngeal branchial cyst, whereas the mucus retention cysts are the commonest to arise from the midline. [1] Sometimes nasopharyngeal cyst may directly refer to Tornwaldt cyst. [2]
Chondrosarcoma is a bone sarcoma, a primary cancer composed of cells derived from transformed cells that produce cartilage. [1] A chondrosarcoma is a member of a category of tumors of bone and soft tissue known as sarcomas. About 30% of bone sarcomas are chondrosarcomas. [2] It is resistant to chemotherapy and radiotherapy. Unlike other primary ...
