Comparative Analysis of Fistula Development After Parotid Gland Surgery: Lateral Parotidectomy Versus Extracapsular Dissection Technique.

PURPOSE: The primary objective of this study was to explore the potential disparity in postoperative fistula occurrence rates between patients who undergo (partial) lateral parotidectomy and those who undergo the extracapsular dissection technique for the management of benign parotid gland tumours. METHODS: A consecutive series of 363 patients treated with (partial) lateral parotidectomy and extracapsular dissection technique for benign parotid gland tumours at one tertiary centre between 2018 and 2022 were included. To evaluate the impact of the surgical technique and possible other risk factors (tumour location, tumour size, Body Mass Index, age, smoking, diabetes mellitus, arterial hypertension) for the development of fistulas, multivariate logistic regression analyses using backward lection were applied to estimate odds ratios (ORs) and 95%-confidence intervals (CIs). RESULTS: In 363 patients, 21 patients (5.8%) developed a fistula. Patients who underwent (partial) lateral parotidectomy had three times higher chance of developing a fistula compared to patients who were operated using the extracapsular dissection technique (ORadjusted = 2.6, 4.1% vs. 12.5%, p = 0.044). In the multivariate analyses, no other risk factors for the development of fistulas were statistically significant in this cohort. The incidence of facial nerve paralysis was not significantly different between the extracapsular dissection and lateral parotidectomy group (5/73 = 6.8% vs. 11/290 = 3.8%, p = 0.333). CONCLUSION: Fistulas occur more often in patients treated by means of a (partial) lateral parotidectomy approach compared to patients treated using the extracapsular dissection technique. Therefore, surgeons should be vigilant about postoperative fistula risks in lateral parotidectomy and consider preventive measures.

[Increased rate of complications of pediatric acute otitis media and sinusitis in 2022/2023]. / Häufung von Komplikationen der akuten Otitis media und Sinusitis bei Kindern 2022/2023.

BACKGROUND: Acute mastoiditis and orbital complications of acute rhinosinusitis are among the most common complications of pediatric infections in otolaryngology. OBJECTIVE: The aim of this study was to investigate the frequency of pediatric acute mastoiditis in the setting of acute otitis media as well as pediatric orbital complications in the setting of acute rhinosinusitis. Data from before the pandemic were compared to data after the end of the COVID-19 restrictions. MATERIALS AND METHODS: Included were hospitalized children who presented with acute mastoiditis from acute otitis media or with orbital complications from acute rhinosinusitis during the period from April 2017 to March 2023. Compared were three periods using descriptive statistics: April 2017 to March 2020 (before the pandemic in Germany), April 2020 to March 2022 (during the contact restrictions of the pandemic), and April 2022 to March 2023 (after the contact restrictions were lifted). RESULTS: A total of 102 children (43 with acute mastoiditis, 42%, and 59 with orbital complications of acute sinusitis, 58%) were included. During the 2022/2023 period, more than twice as many children with acute mastoiditis and approximately three times as many children with orbital complications of acute rhinosinusitis were hospitalized compared to the average of the periods 2017/2018, 2018/2019, and 2019/2020. In the 2021/2022 period, the number of these patients was below the average of previous years. CONCLUSION: This year's seasonal cluster of upper respiratory tract infections is associated with a higher-than-average incidence of orbital complications and mastoiditis.
