Pharynx
The pharynx (plural: pharynges) is an organ found in vertebrates and invertebrates, though the structure is not universally the same across the species. In humans the pharynx is part of the digestive system and also of the conducting zone of the respiratory system. (The conducting zone also includes the nose, larynx, trachea, bronchi, and bronchioles, and their function is to filter, warm, and moisten air and conduct it into the lungs.) The pharynx makes up the part of the throat situated immediately posterior to the nasal cavity, posterior to the mouth and superior to the esophagus and larynx. The human pharynx is conventionally divided into three sections: the nasopharynx, the oropharynx and the laryngopharynx. It is also important in vocalization.
In humans there are two sets of pharyngeal muscles that form the pharynx, determining the shape of its lumen. These are arranged as an inner layer of longitudinal muscles and an outer circular layer.
Structure
Nasopharynx
The upper portion of the pharynx, the nasopharynx, extends from the base of the skull to the upper surface of the soft palate. It includes the space between the internal nares and the soft palate and lies above the oral cavity. The adenoids, also known as the pharyngeal tonsils, are lymphoid tissue structures located in the posterior wall of the nasopharynx. Waldeyer's tonsillar ring is an annular arrangement of lymphoid tissue in both the nasopharynx and oropharynx.

Nasopharyngeal carcinoma (NPC), or nasopharynx cancer, is the most common cancer originating in the nasopharynx, most commonly in the postero-lateral nasopharynx or pharyngeal recess (fossa of Rosenmüller), accounting for 50% of cases. NPC occurs in children and adults. NPC differs significantly from other cancers of the head and neck in its occurrence, causes, clinical behavior, and treatment. It is vastly more common in certain regions of East Asia and Africa than elsewhere, with viral, dietary and genetic factors implicated in its causation.[1] It is most common in males. It is a squamous cell carcinoma of an undifferentiated type. Squamous epithelial cells are a flat type of cell found in the skin and the membranes that line some body cavities. Differentiation means how different the cancer cells are from normal cells. Undifferentiated cells are cells that do not have their mature features or functions. NPC may present as a lump or a mass on both sides towards the back of the neck. These lumps usually are not tender or painful but appear as a result of the metastatic spread of the cancer to the lymph nodes, thus causing the lymph nodes to swell. Lymph nodes are defined as glands that function as part of the immune system and can be found throughout the body.[2] Swelling of the lymph nodes in the neck is the initial presentation in many people, and the diagnosis of NPC is often made by lymph node biopsy. Signs of nasopharyngeal cancer may appear as headaches, a sore throat, and trouble hearing, breathing, or speaking.[3] Additional symptoms of NPC include facial pain or numbness, blurred or double vision, trouble opening the mouth, or recurring ear infections. If the ear infection does not present with an upper respiratory tract infection, then an examination should be done on the nasopharynx. This is due to the fact that, in adults, ear infections are less common than in children.[2] Signs and symptoms related to the primary tumor include trismus, pain, otitis media, nasal regurgitation due to paresis (loss of or impaired movement) of the soft palate, hearing loss and cranial nerve palsy (paralysis). Larger growths may produce nasal obstruction or bleeding and a "nasal twang". Metastatic spread may result in bone pain or organ dysfunction. Rarely, a paraneoplastic syndrome of osteoarthropathy (diseases of joints and bones) may occur with widespread disease.[citation needed]

In this video, Dr. Katie Bailey takes us quickly through the nasopharynx, a common location of malignancies in the head and neck, and walks us through some quick samples of how they are staged.
0:00 Review of the anatomy of the nasopharynx. The nasopharynx is behind the palate and includes the clivus. The nasopharynx is largely lined by squamous mucosa with lymphoid tissues and muscles. An important landmark is the torus tubarius and fossa of Rosenmuller.
0:39 Nasopharyngeal cancer staging, like other subsites, is based on a T, N, M stage. Nasopharyngeal cancers are predominantly staged based on whether adjacent structures, such as surrounding soft tissues or the skull base, are involved. Unlike the other tumor sites, size is not involved in the T staging.
1:11 Example case 1. There is a soft tissue mass filling the nasopharynx, asymmetrically larger on the right. Erosion of the adjacent bony structures, including the clivus, are important. The tumor is extending into the sphenoid sinus. Involvement of the bony structures and sinuses makes this is a T3 tumor, and there were no nodes or distant metastases (not shown).
2:13 There is a more subtle example of bone erosion of the posterior wall of the sphenoid sinus and left carotid canal along with the clivus.
2:55 Example case 2. There is a soft tissue mass eroding the petrous apex and left aspect of the clivus. MRI better shows the extent of the involvement, where you can see that there is intracranial involvement into Meckel’s cave (trigeminal foramen). The intracranial involvement makes this a T4 tumor. There were no nodes or distant metastases (not shown).
4:01 Example case 3. In this case, there are necrotic lymph nodes in the parapharyngeal and prevertebral space as well as extending down the neck at multiple internal jugular levels. The original CT did not show a mass in the nasopharynx, but because of the nodes, a nasopharyngeal cancer is suspected. The PET/CT is able to locate the abnormality along the left torus tubarius. The local nature of this tumor makes it T1, but the bilateral lymph nodes make it an N3 for nodes.
5:19 Extra case. An incidental polypoid mass is seen in the left nasopharynx on a brain MRI with minimal peripheral enhancement and central reduced diffusion. The homogeneously low T2 appearance and reduced diffusion make this suspicious for lymphoma, although you would not be able to tell until this lesion had been biopsied.

Nasopharyngeal carcinoma (NPC), or nasopharynx cancer, is the most common cancer originating in the nasopharynx, most commonly in the postero-lateral nasopharynx or pharyngeal recess (fossa of Rosenmüller), accounting for 50% of cases. NPC occurs in children and adults. NPC differs significantly from other cancers of the head and neck in its occurrence, causes, clinical behavior, and treatment. It is vastly more common in certain regions of East Asia and Africa than elsewhere, with viral, dietary and genetic factors implicated in its causation.[1] It is most common in males. It is a squamous cell carcinoma of an undifferentiated type. Squamous epithelial cells are a flat type of cell found in the skin and the membranes that line some body cavities. Differentiation means how different the cancer cells are from normal cells. Undifferentiated cells are cells that do not have their mature features or functions. NPC may present as a lump or a mass on both sides towards the back of the neck. These lumps usually are not tender or painful but appear as a result of the metastatic spread of the cancer to the lymph nodes, thus causing the lymph nodes to swell. Lymph nodes are defined as glands that function as part of the immune system and can be found throughout the body.[2] Swelling of the lymph nodes in the neck is the initial presentation in many people, and the diagnosis of NPC is often made by lymph node biopsy. Signs of nasopharyngeal cancer may appear as headaches, a sore throat, and trouble hearing, breathing, or speaking.[3] Additional symptoms of NPC include facial pain or numbness, blurred or double vision, trouble opening the mouth, or recurring ear infections. If the ear infection does not present with an upper respiratory tract infection, then an examination should be done on the nasopharynx. This is due to the fact that, in adults, ear infections are less common than in children.[2] Signs and symptoms related to the primary tumor include trismus, pain, otitis media, nasal regurgitation due to paresis (loss of or impaired movement) of the soft palate, hearing loss and cranial nerve palsy (paralysis). Larger growths may produce nasal obstruction or bleeding and a "nasal twang". Metastatic spread may result in bone pain or organ dysfunction. Rarely, a paraneoplastic syndrome of osteoarthropathy (diseases of joints and bones) may occur with widespread disease.[citation needed]

In this video, Dr. Katie Bailey takes us quickly through the nasopharynx, a common location of malignancies in the head and neck, and walks us through some quick samples of how they are staged.
0:00 Review of the anatomy of the nasopharynx. The nasopharynx is behind the palate and includes the clivus. The nasopharynx is largely lined by squamous mucosa with lymphoid tissues and muscles. An important landmark is the torus tubarius and fossa of Rosenmuller.
0:39 Nasopharyngeal cancer staging, like other subsites, is based on a T, N, M stage. Nasopharyngeal cancers are predominantly staged based on whether adjacent structures, such as surrounding soft tissues or the skull base, are involved. Unlike the other tumor sites, size is not involved in the T staging.
1:11 Example case 1. There is a soft tissue mass filling the nasopharynx, asymmetrically larger on the right. Erosion of the adjacent bony structures, including the clivus, are important. The tumor is extending into the sphenoid sinus. Involvement of the bony structures and sinuses makes this is a T3 tumor, and there were no nodes or distant metastases (not shown).
2:13 There is a more subtle example of bone erosion of the posterior wall of the sphenoid sinus and left carotid canal along with the clivus.
2:55 Example case 2. There is a soft tissue mass eroding the petrous apex and left aspect of the clivus. MRI better shows the extent of the involvement, where you can see that there is intracranial involvement into Meckel’s cave (trigeminal foramen). The intracranial involvement makes this a T4 tumor. There were no nodes or distant metastases (not shown).
4:01 Example case 3. In this case, there are necrotic lymph nodes in the parapharyngeal and prevertebral space as well as extending down the neck at multiple internal jugular levels. The original CT did not show a mass in the nasopharynx, but because of the nodes, a nasopharyngeal cancer is suspected. The PET/CT is able to locate the abnormality along the left torus tubarius. The local nature of this tumor makes it T1, but the bilateral lymph nodes make it an N3 for nodes.
5:19 Extra case. An incidental polypoid mass is seen in the left nasopharynx on a brain MRI with minimal peripheral enhancement and central reduced diffusion. The homogeneously low T2 appearance and reduced diffusion make this suspicious for lymphoma, although you would not be able to tell until this lesion had been biopsied.
Thanks for checking out this quick video on nasopharyngeal cancer staging. Be sure to tune back in for additional videos on staging of the other head and neck subsites.

Pharynx
The pharynx (plural: pharynges) is an organ found in vertebrates and invertebrates, though the structure is not universally the same across the species. In humans the pharynx is part of the digestive system and also of the conducting zone of the respiratory system. (The conducting zone also includes the nose, larynx, trachea, bronchi, and bronchioles, and their function is to filter, warm, and moisten air and conduct it into the lungs.) The pharynx makes up the part of the throat situated immediately posterior to the nasal cavity, posterior to the mouth and superior to the esophagus and larynx. The human pharynx is conventionally divided into three sections: the nasopharynx, the oropharynx and the laryngopharynx. It is also important in vocalization.
In humans there are two sets of pharyngeal muscles that form the pharynx, determining the shape of its lumen. These are arranged as an inner layer of longitudinal muscles and an outer circular layer.
Structure
Nasopharynx
The upper portion of the pharynx, the nasopharynx, extends from the base of the skull to the upper surface of the soft palate. It includes the space between the internal nares and the soft palate and lies above the oral cavity. The adenoids, also known as the pharyngeal tonsils, are lymphoid tissue structures located in the posterior wall of the nasopharynx. Waldeyer's tonsillar ring is an annular arrangement of lymphoid tissue in both the nasopharynx and oropharynx.
