Multiple cervical bronchogenic cysts.

Bronchogenic cysts are rare, benign, congenital lesions that occur as a result of aberrant development of the tracheobronchial tree during embryogenesis. They usually present during the first decade of life and are encountered predominantly within the mediastinum or the lung parenchyma. In a few instances, they appear within the neck mimicking a neoplasm and, depending on their size and site, may also cause acute upper respiratory obstruction. We describe a case of two cervical bronchogenic cysts adjacent to the larynx in a child who presented with a hoarse voice.

A simple and reliable predictor for an adequate laryngeal view with rigid endoscopic laryngoscopy.

OBJECTIVES: It is sometimes impossible to obtain an adequate laryngeal view during rigid endoscopic laryngoscopy. This may be due to a high tongue base. Our study seeks to determine a correlation between tongue base level and the adequacy of laryngeal view obtained with a 70-degree rigid endoscope. STUDY DESIGN AND SETTING: Over a period of 4 months, patients from a voice clinic were gathered and categorized into class I to III according to Mallampati et al (1985). Rigid laryngo-videostroboscopy was conducted to assess the larynx and the adequacy of the view was recorded. RESULTS: 74 patients were recruited. The number of adequate views were: class I = 18/20 (90%); class II = 20/33 (60.6%); class III = 7/21 (33.3%). chi 2 analysis demonstrated significance trend in all 3 classes. CONCLUSION: The level of the tongue base correlated well with the adequacy of laryngeal view obtained from a 70-degree rigid endoscope. This can be used to predict the success of obtaining adequate views during rigid laryngoscopy.

How to perform adequate nasal packing in posterior epistaxis with difficult access.

Inadequate nasal packing in the treatment of posterior epistaxis can result in an increase in patient morbidity and mortality, and also hospital expenditure. The presence of a septal spur or septal deviation anterior to the bleeding may prevent sufficient local pressure over the bleeding point with a ribbon gauze pack. A modified Jobson-Horne probe can be used to ensure a tight ribbon gauze application over the bleeding point behind the septal spur or deviation.
