[The new guideline "Treatment of Inflammatory Diseases of the Palatine Tonsils - Tonsillitis" : Impact in clinics and surgeries]

Does a tonsillectomy indicated according to the German S2k guideline affect short-term quality of life in adults?

BACKGROUND

Tonsillectomy (TE) for recurrent tonsillitis (RT) is one of the most common surgical interventions. Since 2015, the indication criteria for TE have become much stricter (German S2k guideline). Patient-reported outcome measures (PROMs) of short-term quality of life (QoL) after TE have not yet been investigated.

PURPOSE

To clarify if stringent indication for TE will better identify patients worthy of surgery and patients' QoL.

METHODS

We prospectively studied the Tonsillectomy Outcome Inventory 14 (TOI-14) responses of 38 RT-patients recruited according to the S2k guideline in 2020 and compared their TOI-14 scores with those of a historical RT cohort from 2006 to 2008 and with a healthy middle-European cohort. New RT patients were assessed before, 2, 4, and 14 days and 6 months after TE. TOI-14 was measured as total and as disease-specific score.

RESULTS

From pre- to 6-month postoperative, patients' QoL was significantly different, measured by TOI-14 (49.92 vs. 6.35; p < 0.001) and disease-specific score (60.35 vs. 9.9; p < 0.001). Preoperative disease-specific score was not different from that of the 2nd and 4th postoperative days but from the 14th postoperative day (60.35 vs. 29.26; p < 0.001). The historical cohort had significantly less RT complaints than the new cohort beforehand, but more dissatisfaction in QoL after TE. New TE patients had worse QoL pre- (49.92 vs. 11.78; p < 0.001) but more QoL postoperatively (6.34 vs. 11.78; p = 0.004) than healthy individuals.

CONCLUSIONS

Our results show that the tightening of the indication criteria for TE was justified and that TE patients significantly benefit from this surgery from day 14.

Tonsillectomy versus tonsillotomy for recurrent acute tonsillitis in children and adults (TOTO): study protocol for a randomized non-inferiority trial

BACKGROUND

Tonsillectomy is one of the most frequently performed surgeries in children and young adults worldwide. For decades, tonsillectomy was the surgical treatment of choice for recurrent acute tonsillitis. Tonsillotomy was used in some countries as an alternative to tonsillectomy only for the treatment of obstructive sleep apnea in young children. In recent years, an increase of tonsillotomy also to treat recurrent acute tonsillitis can be observed. Therefore, the German Institute for Quality and Efficiency in Health Care (IQWiG) was commissioned by the Federal Joint Committee (G-BA) to investigate whether tonsillotomy offers advantages compared to tonsillectomy. The meta-analysis of the IQWiG including studies until 2016 revealed that the long-term benefits and harms of tonsillotomy compared to tonsillectomy are unclear. Consequently, the G-BA performed a European call for a clinical trial. A consortium of the German Professional Association of ENT-surgeons (BVHNO), the German Society of Oto-Rhino-Laryngology, Head and Neck Surgery (DGHNO-KHC), and the Jena University Hospital were finally selected to perform the TOTO study.

METHODS

TOTO is a multicenter, 1:1 two-arm, randomized non-blinded non-inferiority trial. Four hundred fifty-four patients ≥ 3 years of age will be randomly allocated to undergo either tonsillotomy or tonsillectomy as surgical treatment of recurrent acute tonsillitis. All participants will be followed up for a total of 24 months. The primary outcome is the number of sore throat days experienced over the 24-month follow-up.

DISCUSSION

TOTO is designed to evaluate the effectiveness and efficiency of tonsillectomy versus tonsillectomy for the management of patients with recurrent acute tonsillitis. Tonsil disease and surgery have a major impact on preschool and school children as well as on economically active young adults, with individual and societal costs through loss of school visits, earnings, and productivity. If tonsillotomy is at least as effective as tonsillectomy but with reduced morbidity, this would reduce costs to the healthcare system and society.

Normative tonsillectomy outcome inventory 14 values as a decision-making tool for tonsillectomy

Purpose

The study aimed to determine normative values for the Tonsillectomy Outcome Inventory 14 (TOI-14) in a healthy middle-European cohort. We also compared these generated values with TOI-14 scores from a patient population with recurrent tonsillitis (RT) and explored the factorial structure of the TOI-14.

Methods

We systematically studied the responses of healthy individuals (reference cohort) and patients with RT (clinical cohort) to the TOI-14 survey. The reference cohort contained 1000 participants, who were recruited using the Respondi panel for market and social science research. This subsample was quoted to the population distribution of the German Microcensus and selected from a non-probability panel. Tonsillitis patients were assessed before and 6 and 12 months after tonsillectomy.

Data were analysed using principal component and exploratory factor analyses.

Results

The PCA revealed three TOI-14 domains (physiological, psychological and socio-economic), which explained 73% of the total variance. The reference cohort perceived a good quality of life (QOL) with a TOI-14 total score of 11.8 (physiological: 8.0, psychological: 5.8, and socio-economic subscale score: 13.9). TOI-14 scores were higher in the patient cohort, indicating that the TOI-14 discriminates between patients with RT and healthy individuals with no RT. Age and female gender significantly influenced the total TOI-14 score, especially in the psychological (age) and socio-economic (gender) subscales.

Conclusion

We have developed a set of normative values that, together with the TOI-14, can determine the disease burden indicating tonsillectomy.

[Recurrent infections of the upper aerodigestive tract in patients with primary immunodeficiency]

BACKGROUND

Primary immunodeficiency is a rare disease of humoral and cellular immune defense, which can lead to severe and recurrent infections of different organs. The diagnosis of this disease is often difficult, and its early identification is necessary for adequate treatment and control.

OBJECTIVE

This study aimed to analyze ear, nose, and throat (ENT) infections in adults and children with a primary immunodeficiency. We attempted to characterize possible warning signs that should trigger an immunologic diagnostic workup.

MATERIALS AND METHODS

The current study comprised a retrospective case series of patients with primary immunodeficiencies. The type of immunodeficiency and the number of ENT infections were recorded.

RESULTS

A total of 85 Patients were included in the study. 56 patients (66%) had an acute exacerbation of chronic rhinosinusitis (n = 28), cervical lymphadenitis (n = 16), acute tonsillitis (n = 14), and acute otitis media (n = 6). Reporting detailed information about the frequencies and dates of infections was not possible, due to the retrospective nature of the analysis.

CONCLUSION

The prevalence of ENT infections in patients with a primary immunodeficiency is increased compared to the normal population. For the ENT specialist, these findings underline the necessity of including primary immunodeficiency in the differential diagnosis and initiating targeted diagnostic methods where indicated. Interdisciplinary collaboration with rheumatologists and immunologists is highly recommended, particularly for pediatric patients.
