Children are able to sing in the same octave as women. When the voices of male teenagers break, they are no longer able to sing in the same octave. For music sung in the same key as women, they can sing in falsetto or drop an octave. See also

If a trauma case or chronic tracheal illnesses were the cause, the first steps of treatment would be to address these underlying issues. If the cause is genetic or the previous underlying issues could not be fixed, other treatments would be assessed. More severe treatments include silicone stenting to prevent tracheal constriction, surgery to strengthen or attempt to rebuild the walls, continuous positive airway pressure that has a machine blow small amounts of air into the trachea to keep it open (mainly at night), or a tracheostomy, which is surgically inserted into the patients neck that leads to the trachea to help with breathing. Another form of treatment may include a tracheobronchoplasty which is a specific surgical procedure that helps control the airway by splinting the trachea. The splint helps strengthen the trachea with the hopes that the symptoms improve. People with tracheobronchomalacia who do not experience symptoms do not need treatment and are often undiagnosed.On 28 May 2013, it was reported that a cure had been developed via a 3D printed windpipe. This cure has currently saved the lives of at least 3 infants. See also
