Overall, in 203 parotid operations, a lateral parotidectomy (77%) was performed in most cases; 94% were primary surgery and 6% were revision surgery. In 89% of patients swelling was the only symptom. Bilateral Warthin tumor was seen in 17% of patients. Of these cases synchronous and metachronous bilateral tumors were observed in 61% and 39%, respectively. The median time period for second contralateral tumor development was 7 years. Postoperative transient facial dysfunction was observed in 31%, which recovered within 3 months in all cases. Evaluation of risk factors revealed that 89% of the subjects were smokers and 66% were heavy smokers. The risk for bilateral Warthin tumors correlated significantly with the amount of nicotine intake (p=0.003).
ZUSAMMENFASSUNG Die Übersichtarbeit fasst die aktuellen Erkenntnisse der Auswirkung der COVID-19-Pandemie für die Arbeit der HNO-Ärztin und des HNO-Arztes zusammen. Die aktuell diskutierte Rolle einer Anosmie oder Hyposmie als COVID-19-assoziiertes Symptom wird dargestellt. Wir diskutieren das klinische Management aller HNO-Fälle, aber insbesondere von COVID-19erkrankten Patienten aus Sicht der HNO-Heilkunde. Ein besonderes Augenmerk gilt den Auswirkungen auf die HNO-Untersuchung und auf HNO-ärztliche Operationen.
In patients presenting with CUP syndrome, p16 immunohistochemistry can serve to locate the primary cancer in the oropharynx. It is a positive prognostic indicator in patients with those heterogeneous cancers.
Introduction:
The Eustachian tube plays a crucial role in pressure equalization between the middle ear and ambient pressure for fast and large pressure differences. In patients with chronic Eustachian tube dysfunction, Eustachian tube balloon dilatation is increasingly used as surgical therapy. Subjectively, many patients report an improvement of the symptoms postoperatively. Hence, there is a need to objectively measure this effect.
Methods:
The objectivity of Eustachian tube balloon dilatation was evaluated using a precise method of measuring Eustachian tube function. In a hypo/hyperbaric pressure chamber, 23 ears in 13 patients were exposed to a standardized profile of compression and decompression before Eustachian tube balloon dilatation and 4 weeks afterwards. Standardized parameters of Eustachian tube function were determined and statistically compared before and 4 weeks after intervention. In addition, an Eustachian Tube Dysfunction Questionnaire-7 (ETDQ7) questionnaire was completed beforehand and 4 weeks postoperatively to determine subjective surgical success.
Results:
The results from the ETDQ7 questionnaire showed a significant improvement in symptoms after Eustachian tube balloon dilatation (p = 0.0002). Objective measurements results showed a significant reduction of the Eustachian tube opening pressure during pressure decrease 4 weeks after intervention (p = 0.0012).
Conclusion:
Eustachian tube balloon dilatation significantly reduced Eustachian tube opening pressure, in addition to subjective improvement of symptoms determined by ETDQ7.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
