     When a person has difficulty in listening when talking to several people in noisy surroundings or on the phone, he or she is aware of hearing loss and visits an ENT clinic. However, in cases where the hearing test results are normal, there is a dissociation between the patients perception of hearing and the test results. Especially in cases where the patient is aware of such difficulty in listening, auditory processing disorder (APD) should be suspected. However, since there are no diagnostic criteria for APD, it is difficult to make a diagnosis. In this study, we approached such cases of APD from the aspects of auditory psychological and cognitive tests and background factors. As a result, we found that binaural hearing tests, rapid speech tests, directional function tests, and HINT are effective tests for extracting complaints of APD. On the other hand, from the cognitive aspect, the assessment of attention and working memory is important for the extraction of APD. As background factors, it is necessary to check for ASD and ADHD tendencies, including those in the gray zone. It is necessary to consider support in daily life by surrounding people for listening difficulties.

     Although endotracheal intubation is routinely performed for surgery under general anesthesia, damage to the larynx and tracheal mucosa could occur during intubation when the procedure is performed by a person with inadequate skill or when there is difficulty in laryngeal deployment. In some cases, the mucosa in the posterior glottis or subglottis becomes necrotic due to the use of an incompatible intubation tube or excessive cuff pressure; in such cases, while there may be no problem except for some bleeding at the time of extubation, the mucosa slowly narrows, eventually resulting in dyspnea. We encountered three such cases within a relatively short period of time at our hospital, and all showed a favorable clinical course. We wish to underscore the importance of preoperative diagnosis and selection of appropriate surgical treatment for each case. Herein, we highlight the importance of preoperative diagnosis and selection of the appropriate surgical treatment for these cases. The pathogenesis of this disease as a medical-induced upper airway stenosis and the importance of appropriate diagnosis and treatment will also be presented herein, with some discussion of the literature.

     Preventive surgery against aspiration is usually performed permanent tracheal stoma to be tube-free, however, patients requiring assisted ventilation for their underlying disease often require a cuffed tracheostomy tube. The tracheostomy tube is designed to fit correctly into the tracheostomy hole, so that it does not usually fit into a permanent tracheal stoma.

     We devised a new preventive surgery against aspiration called “Cricoid Cartilage-preserving-type Laryngectomy,” in which we shaped the permanent tracheal stoma such that it became closer in shape and dimension to a tracheostomy hole by preserving the cricoid cartilage. We have performed our original surgery in three cases so far. We evaluated the radius of curvature of the permanent tracheal stoma by using sagittal computed tomographic images and compared the radius of curvature of the permanent tracheal stoma on our surgery with total laryngectomy. We found that the radius of curvature obtained by our surgery was closer to the radius of curvature of the tracheostomy tube than that obtained by total laryngectomy. Cricoid cartilage-preserving-type laryngectomy is useful as a preventive surgery against aspiration in patients who require a tracheostomy tube for ventilatory management.
