Rhinogenic deafness refers to hearing loss resulting from inflammation of the nasopharynx, Eustachian tube, and middle ear. At the Center, in addition to traditional inhalation treatments, endotubal insufflations are performed, which inject sulfur gas into the middle ear through the Eustachian tube.

To fully understand the treatment options, some basic anatomy is needed. The ear can be divided into three parts: the outer ear, with the pinna and auditory canal, which collect sounds and transmit them to the tympanic membrane, which receives them through the ossicular chain—the hammer, the anvil, and the stirrup—and transmits them to the inner ear, which transforms the sounds into nerve impulses. In the middle ear, in addition to the ossicles, is the internal opening of the Eustachian tube, a tube about 3 or 4 cm long, which extends to the pharynx above the soft palate. This allows air to enter the middle ear, balancing the pressure on both sides of the tympanic membrane, a necessary condition for its proper functioning. A small inflammation of the Eustachian tube is enough to block it, as often occurs with inflammation of the nose and pharynx, and this results in poor functioning of the ossicular chain, causing ringing in the ears, hearing loss, and a feeling of local congestion. Before being admitted for treatment, patients are always examined by a specialist and undergo audiometric and impedance testing, performed in the audiometry department. The former analyzes all audible sound frequencies and determines the hearing threshold. The impedance testing, on the other hand, evaluates the elasticity of the eardrum and ossicles and their efficiency in transmitting sound, and indirectly, the presence of middle ear catarrh. These tests are essential for reaching a correct diagnosis, designing the appropriate treatment, and evaluating improvement at the end of treatment.
