Biophilia Tracker X4 for nasopharyngeal examination

In 2006, the Institute of Practical Psychophysics introduced 3D NLS-graphy as an examination method for the first time. Since then, we have gained extensive experience in the diagnosis of various pathologies of the upper respiratory tract. The institute has developed NLS-graphic semiotics, created spectral etalons for various genetic nasopharyngeal tumors, and formulated spectrum-based differential diagnostic standards for malignant tumors, benign tumors, and non-tumor pathologies.

The indications for NLS angiography are symptoms related to the development of nasopharyngeal tumors, which can be divided into nasal, ear and nervous system according to localization.

Nasal shortness of breath occurs when tumors are located in the nasopharynx. Nasal breathing is getting shorter and shorter, accompanied by mucopurulent and purulent discharge, and there is a mixture of blood in the nasal cavity. The number of complaints of nasal shortness of breath depends on the exogenous components of the tumor closing the opening and additional inflammation. Bleeding can be detected if there are recurrent ulcers on the surface; it becomes dangerous for angiofibromas.

If the tumor is located on the front wall of the auditory tube orifice, Trotter syndrome may occur: hearing impairment on the affected side of the head, neuralgia, numbness of the third branch of the trigeminal nerve, and unilateral limited soft palate movement. If the tumor is located near the mouth of the auditory tube, the main manifestations are hearing impairment, tinnitus, and ear fullness.

If the tumor spreads to surrounding tissue, neurological symptoms may occur. If the tumor spreads to the base of the skull, the posterior and lateral walls of the nasopharynx, the most common neurological disorders appear, and symptoms of almost all pairs of cranial nerves are detected: paralysis of the abducens nerve, facial nerve, immobility of half of the larynx, Adhesions, sensitivity, taste and tongue declination disorders.

The above diseases develop when tumors persist. In the early stages of the development of nasopharyngeal tumors, the symptoms of the disease disappear, and the first clinical manifestation of nasopharyngeal cancer is cervical lymphadenopathy in 50% of cases. This fact demonstrates that NPC is characterized by early regional metastatic disease. The size of the primary tumor does not correlate with the presence of regional metastatic disease. Even with small and superficial invasion of the primary tumor, multiple metastases can be detected from the involved side and crosswise and bilaterally, often in the deep jugular lymph node group. Large-area metastases cause pain and Gorner's syndrome occurs, manifested by shrinkage of the palpebral fissures and retraction of the pupils and eyeballs.
