An unusual case of duplication of the foregut arising from the posterior pharyngeal wall is presented. Pertinent embryological and etiological considerations are discussed and a literature review included.
To evaluate the reliability of frozen section diagnosis we reviewed a series of 1146 consecutive frozen sections performed during a 5-year period. The frozen section diagnosis was then compared to that found on paraffin section and the results categorized into 12 regions in the head and neck. We found an overall reliability of 96%. The total percentage of false positive and false negative results were 0.35% and 3% respectively. Frozen section diagnosis was most accurate on the submandibular gland (no errors), nose and paranasal sinuses (no error), followed by the thyroid gland (0.8% error). Areas in which frozen section diagnoses were least accurate included the nasopharynx (12.5% error) and the oropharynx (8.7% error). We conclude that frozen section diagnosis is highly accurate in most regions of the head and neck.
Fourteen cases of adult acute epiglottitis with their clinical manifestations are presented. The history, etiology, pathophysiology, and diagnosis of the disease are reviewed. The controversies of management are discussed and a concise management protocol is outlined.
Rhinitis medicamentosa, the syndrome of rebound nasal congestion secondary to prolonged topical intranasal use of vasoconstrictors, is reviewed. In this condition, the nasal airway is very obstructed; atrophic rhinitis is the most serious complication. Management consists of withdrawing the offending nasal spray and alleviating the nasal obstruction by means of any of several treatment modalities.
