Subvocal stenosis can usually be treated by removing the stenotic tissue under laryngoscopy or performing a low tracheotomy. There are congenital subglottic stenosis and acquired subglottic stenosis. Congenital subglottic stenosis is caused by a developmental abnormality, and newborns are born with a laryngeal sound. Acquired subvocal stenosis, in most cases, is the result of trauma. Patients may have laryngeal tinnitus, barking cough, rattling of the breath, and dyspnea. Patients with mild obstruction and no obvious symptoms can usually be treated without special treatment, but care should be taken to prevent respiratory infections. Patients with subglottic stenosis may also have a laryngoscope placed transorally and the stenotic tissue removed by plasma or laser surgery under the laryngoscope. In special populations with recurrent tissue growth under the vocal folds, T-tube implantation with local dilatation for six months to more than eight months after the above mentioned surgery is recommended. Patients with symptoms of dyspnea from the stenosis may undergo a low level tracheotomy to improve dyspnea. Early medical attention is recommended to relieve the associated symptoms with appropriate treatment under medical supervision.
