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.

A histological comparison of deep and superficial lobe pleomorphic adenomas of the parotid gland.

BACKGROUND: Excision of parotid superficial lobe pleomorphic adenomas requires removal of a surrounding cuff of normal parotid tissue. Less aggressive dissection in removing pleomorphic adenomas that occur in the deep lobe of the parotid gland does not seem to compromise prognosis in these patients. We attempted to define histologic characteristics, differentiating superficial and deep lobe tumors, in an attempt to explain this clinical phenomenon. METHOD: Thirty-one pleomorphic adenomas, 12 deep-lobe tumors, and 19 superficial lobe tumors were analyzed and compared, looking at tumor size, capsule thickness, penetration of tumor through capsule, and predominant cell types present. RESULTS: The superficial lobe tumors had significantly thinner capsules (p =.02). There was increased extracapsular extension of tumor in the superficial lobe group compared with the deep lobe group (79% and 58%, respectively). The tumors were larger in patients with deep lobe lesions (2.6 cm vs 3.6 cm). There was no difference in predominant cell types. CONCLUSIONS: The anatomic location of deep lobe tumors is a likely explanation for the histologic differences observed in this study. These important differences allow less aggressive dissection in deep lobe tumors without compromising prognosis.

Genetic screening for deafness.

Genetic testing for deafness has become a reality. It has changed the paradigm for evaluating deaf and hard-of-hearing persons and will be used by physicians for diagnostic purposes and as a basis for treatment and management options. Although mutation screening is currently available for only a limited number of genes, in these specific instances, diagnosis, carrier detection, and reproductive risk counseling can be provided. In the coming years there will be an expansion of the role of genetic testing and counseling will not be limited to reproductive issues. Treatment and management decisions will be made based on specific genetic diagnoses. Although genetic testing may be a confusing service for the practicing otolaryngologist, it is an important part of medical care. New discoveries and technologies will expand and increase the complexity of genetic testing options and it will become the responsibility of otolaryngologists to familiarize themselves with current discoveries and accepted protocols for genetic testing.

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.
