Reduced risk of primary postoperative hemorrhage after tonsil surgery in Sweden: Results from the national tonsil surgery register in Sweden covering more than 10 years and 54,696 operations

To analyze the incidence of primary bleeding following tonsil surgery and to evaluate risk factors.

Tonsil surgery efficiently relieves symptoms: analysis of 54 696 patients in the National Tonsil Surgery Register in Sweden

Abstract Conclusion: Patients operated with tonsillar surgery report a high degree of symptom relief 6 months after surgery. Objective: The purpose of this study was to analyze symptom relief 6 months after tonsil surgery in relation to age, indication, surgical procedure, primary bleeding and unplanned postoperative visits. The National Tonsil Surgery Register in Sweden offers data from 54 696 patients registered during 1997–2008. Methods: This was a prospective assessment by questionnaire. Data were collected using three questionnaires, two completed by professionals and one 6 months postoperatively by the parents/patients. Results: Among 54 696 patients, the most common surgical indications were obstruction (49.7%), followed by recurrent tonsillitis (35.2%). Symptom relief 6 months after surgery was high in all indication groups (>92%), and highest for patients operated on the indication peritonsillitis (>98%). The indications obstruction, recurrent tonsillitis or chronic tonsillitis reported a high degree (>96%) of symptom relief. Of the patients who underwent tonsillectomy with adenoidectomy, 97.5% were symptom-free compared to 96% of patients who had tonsillectomy alone and 96.1% who underwent tonsillotomy (p < 0.0001). In all, 13.9% of patients required an unplanned visit to the clinic postoperatively. Only 148 of 54 696 patients reported worsening of symptoms after surgery.

Thermal Oral-Pharyngeal Stimulation and Elicitation of Swallowing

The influence of thermal stimulation of the oral and pharyngeal mucosa on the elicitation of swallowing was studied in 14 healthy volunteers. The Repeated Dry Swallowing Test was used to study the ability to elicit swallows. The test consists of 11 manometrically recorded dry swallows performed at maximum speed. The time between swallows 1 and 11 (Swallowing Test Time) is considered a measure of the ease of eliciting the swallowing reflex. The study includes two controlled experiments, each consisting of an active test done immediately after a cold stimulus and a control done after a stimulus at body temperature. In one experiment the stimulus consisted of stimulation of the fauces with a laryngeal mirror and in the other of swallowing water. Each subject served as his or her own control. The order of the tests was randomized and the results read blindly. In the mirror experiment, the swallowing test times obtained after application of a cold laryngeal mirror did not differ significantly from those obtained after stimulation at body temperature. In the water experiment, swallowing test times were shorter after swallowing cold water compared to those after swallowing water at body temperature in 11 of the 14 volunteers (n.s.). The concept that swallowing is significantly facilitated by cold applied to the oral-pharyngeal mucosa was thus not supported by the present study. The importance of these findings is discussed.
