“…Lowvelocity handguns normally lead to less intense trauma. In rare cases laryngocele is seen after a shotgun injury [12]. Fortunately, these cases were very rarely seen at our institutions, but they will remain of concern as long as gun-related violence continues [16].…”

In contrast to internal trauma to the larynx caused by endolaryngeal procedures, trauma to the larynx caused by external forces is relatively rare. Nevertheless, the great variety of these external traumata warrants a thorough diagnosis and understanding of each case as well as a standardized and accepted method for classifying these injuries. These preconditions will facilitate successful therapy. At our three institutions cases of external trauma to the larynx, including the mechanisms of trauma, were reviewed and analyzed. Cases were classified according to the mechanisms and the sequelae of trauma. The three major categories were (a) external trauma due to the impact of blunt objects, (b) trauma after tearing of the neck and the larynx longitudinally, and (c) external trauma caused by sharp objects and gunshots. In the great majority of cases external trauma to the larynx was caused by blunt pressure and was most often due to strangulation in the course of (attempted) suicide or homicide. In a smaller number of cases sharp instruments caused external traumata. In patients surviving the immediate trauma a meticulous laryngological assessment is necessary. In addition to indirect laryngoscopy, we consider microlaryngoscopy as being indicated for investigating the soft tissues of the endolarynx. The status of the laryngeal skeleton can be determined more precisely via high-resolution computed tomography and ultrasound. Early diagnosis and appropriate therapy have a significant impact on the patient's condition later, especially as regards scar formation, ease of breathing, and voice quality.

“…The air must pass freely and fluently through the nostrils with minimal resistance [1]. Unusual enlargement of anatomical structures in this area, such as adenoids, hypertrophy of nasal turbinates or tonsils, nasal injury, nasal septum deviation, neoplasms, congenital nasal deformities, foreign bodies, polyps, or allergic rhinitis, can obstruct the airflow within the nasorespiratory channel [1][2][3][4][5][6]. This obstruction can impair nasal breathing, resulting in an oral mode of respiration [1].…”

Background: Rapid maxillary expansion is a common treatment for posterior cross-bites that has also shown to improve nasal breathing.Methods: Thirteen oral breather patients with posterior cross-bite were studied. Treatment consisted in rapid maxillary expansion with a fully bonded appliance including a bite-block and a hyrax expansion screw. Before and after treatment, CT scans and active anterior rhinomanometry were performed to each patient. Data was analyzed with the non-parametric Wilcoxon statistical test and correlation between palatal expansion and increase of airflow in each patient was assessed.Results: The CT scan showed that transversal dimensions were significantly increased (P<0.001) in most areas after treatment, considering the right and left side separately. Rhinomanometry also showed statistical differences (P<0.001) in all parameters studied when compared before and after treatment. Positive correlation was observed between palatal expansion and increase of airflow.Conclusions: All patients improved oral breathing habit clinically and there is also statistical evidence that the nasal cavity increased its transversal dimensions, measured by CT scan and that patients increased their airflow through the nasal cavity, measured by rhinomanometry.
