Effect of the German tonsillitis guideline on indication for tonsil surgery in patients with recurrent acute tonsillitis: a population-based study.

Evidence-based indication for tonsil surgery in patients with recurrent acute tonsillitis (RAT) is an ongoing matter of debate. Since introduction of the German tonsillitis guideline in 2015, the indication criteria for tonsil surgery have become much stricter. It is unclear, if this has changed the indication policy. A retrospective population-based study was performed including all 1398 patients with RAT admitted for tonsil surgery in all Thuringian hospitals in 2011, 2015, and 2019. Changes over the years concerning patients' characteristics, number of tonsillitis episodes in the last 12 months treated with antibiotics (T12), and decision for tonsillectomy or tonsillotomy were analyzed using univariable and multivariable statistics. The surgical rates decreased from 28.56/100,000 population in 2011 to 23.57 in 2015, and to 11.60 in 2019. The relative amount of patients with ≥ 6 T12 increased from 14.1% in 2011 over 13.3% in 2015 to 35.9% in 2019. Most patients received a tonsillectomy (98% of all surgeries). Decision for tonsillotomy was seldom (1.2%). Multinomial logistic regression analysis with the year 2011 as reference showed that compared to the year 2015, the age of the patients undergoing surgery increased in 2015 (Odds ratio [OR] = 1.024; 95% confidence interval [CI] = 1.014-1.034; p < 0.001), and also in 2019 (OR 1.030: CI 1.017-1.043; p < 0.001). Compared to 2011, the number T12 was not higher in 2015, but in 2019 (OR 1.273; CI 1.185-1.367; p < 0.001). Stricter rules led to lower tonsil surgery rates but to a higher proportion of patients with ≥ 6 T12 before surgery. Tonsillectomy remained the dominating technique.

Multicenter Observational Study to Evaluate the Diagnostic Value of Sonography in Patients with Chronic Rhinosinusitis.

(1) Background: Computed tomography (CT) is considered mandatory for assessing the extent of pathologies in the paranasal sinuses (PNS) in chronic rhinosinusitis (CRS). However, there are few evidence-based data on the value of ultrasound (US) in CRS. This multicenter approach aimed to compare diagnostic imaging modalities in relation to findings during surgery. (2) Methods: 127 patients with CRS were included in this prospective multicenter study. Patients received preoperative US and CT scans. The sensitivity and specificity of CT and US were extrapolated from intraoperative data. (3) Results: CT scans showed the highest sensitivity (97%) and specificity (67%) in assessing CRS. Sensitivities of B-scan US were significantly lower regarding the maxillary sinus (88%), the ethmoid sinus (53%), and the frontal sinus (45%). The highest overall sensitivity was observed for assessing the pathology of the maxillary sinus. (4) Conclusions: We observed high accuracy with CT, confirming its importance in preoperative imaging in CRS. Despite the high US expertise of all investigators and a standardized examination protocol, the validity of CT was significantly higher than US. Ultrasound of the PNS sinuses is applicable in everyday clinical practice but lacks diagnostic accuracy. Nevertheless, it might serve as a complementary hands-on screening tool to directly correlate the clinical findings in patients with PNS disease.

Patients with non-idiopathic sudden sensorineural hearing loss show hearing improvement more often than patients with idiopathic sudden sensorineural hearing loss.

INTRODUCTION: To compare inpatient treated patients with idiopathic (ISSNHL) and non-idiopathic sudden sensorineural hearing loss (NISSNHL) regarding frequency, hearing loss, treatment and outcome. METHODS: All 574 inpatient patients (51% male, median age: 60 years) with ISSNHL and NISSNHL, who were treated in federal state Thuringia in 2011 and 2012, were included retrospectively. Univariate and multivariate statistical analyses were performed. RESULTS: ISSNHL was diagnosed in 490 patients (85%), NISSNHL in 84 patients (15%). 49% of these cases had hearing loss due to acute otitis media, 37% through varicella-zoster infection or Lyme disease, 10% through Menière disease and 7% due to other reasons. Patients with ISSNHL and NISSNHL showed no difference between age, gender, side of hearing loss, presence of tinnitus or vertigo and their comorbidities. 45% of patients with ISSNHL and 62% with NISSNHL had an outpatient treatment prior to inpatient treatment (p < 0.001). The mean interval between onset of hearing loss to inpatient treatment was shorter in ISSNHL (7.7 days) than in NISSNHL (8.9 days; p = 0.02). The initial hearing loss of the three most affected frequencies in pure-tone average (3PTAmax) scaled 72.9 dBHL ± 31.3 dBHL in ISSNHL and 67.4 dBHL ± 30.5 dBHL in NISSNHL. In the case of acute otitis media, 3PTAmax (59.7 dBHL ± 24.6 dBHL) was lower than in the case of varicella-zoster infection or Lyme disease (80.11 dBHL ± 34.19 dBHL; p = 0.015). Mean absolute hearing gain (Δ3PTAmaxabs) was 8.1 dB ± 18.8 dB in patients with ISSNHL, and not different in NISSNHL patients with 10.2 dB ± 17.6 dB. A Δ3PTAmaxabs ≥ 10 dB was reached in 34.3% of the patients with ISSNHL and to a significantly higher rate of 48.8% in NISSNHL patients (p = 0.011). CONCLUSIONS: ISSNHL and NISSNHL show no relevant baseline differences. ISSNHL tends to have a higher initial hearing loss. NISSHNL shows a better outcome than ISSNHL.

Hospitalization for epistaxis: a population-based healthcare research study in Thuringia, Germany.

PURPOSE: Epistaxis is the most common ENT emergency. The aim was to determine population-based data on severe epistaxis needing inpatient treatment. METHODS: Retrospective population-based cohort study in the federal state Thuringia in 2016 performed on all 840 inpatients treated for epistaxis in otolaryngology departments (60.1% male, median age: 73 years; 63.9% under anticoagulation). The association between patients' and treatment characteristics and longer inpatient stay (≥ 4 days) as well as readmission for recurrent epistaxis was analyzed using univariable and multivariable statistics. RESULTS: The overall incidence of epistaxis needing inpatient treatment was higher for men (42 per 100,000) than for women (28 per 100,000). The highest incidence was reached for men > 85 years (222 per 100,000). Most important independent predictors for longer inpatient stay were localization of the bleeding not in the anterior nose (OR = 2.045; CI = 1.534-2.726), recurrent bleeding during inpatient treatment (OR = 2.142; CI = 1.508-3.042), no electrocoagulation (OR = 2.810; CI = 2.047-3.858), and blood transfusion (OR = 2.731; CI = 1.324-5.635). Independent predictors for later readmission because of recurrent epistaxis were male gender (OR = 1.756; CI = 1.155-2.668), oral anticoagulant use (OR = 1.731; CI = 1.046-2.865), and hereditary hemorrhagic telangiectasia (OR = 13.216; CI 5.102-34.231). CONCLUSIONS: Inpatient treatment of epistaxis seems to be variable in daily routine needing standardization by clinical guidelines and strategies to shorten inpatient treatment and to reduce the risk of readmission.

[A german-wide inquiry about the significance of ultrasound in the head and neck area]. / Deutschlandweite Umfrage zur Wertigkeit der Ultraschalldiagnostik im Kopf-Hals-Bereich.

A german-wide inquiry was performed for the evaluation of diagnostic ultrasound, current applications and the significance in the head and neck area throughout 2013 and 2014. We focused on the integration of the ultrasound diagnostic in the ENT routine and compared the implementation of ultrasound in the practice and in the clinical setting. Furthermore the current concepts of standardization in sonographic documentation, training guidelines and assessment of clinical impact of the ultrasound were evaluated.

Inpatient treatment of patients with idiopathic sudden sensorineural hearing loss: a population-based healthcare research study.

PURPOSE: The aim was to determine inpatient treatment rates of idiopathic sudden sensorineural hearing loss (ISSNHL) with focus on diagnostics, treatment, and outcome. METHODS: A retrospective population-based study in the federal state Thuringia in 2011 and 2012 was performed on all 490 inpatients (51% females, median age: 60 years) treated for ISSNHL (Median duration: 7 days). The association between analyzed parameters and the probability of recovery was tested using univariable and multivariable statistics. RESULTS: The inpatient treatment rate for ISSNHL was 11.23 per 100,000. 172 patients (35%) had an outpatient treatment prior to inpatient treatment. For pure-tone audiometry of the three most affected frequencies (3PTAmax), the initial median hearing loss was 66.67 dB, the median absolute hearing gain ΔPTAabs was 10.0 dB, and the median relative hearing gain in relation with the contralateral side ΔPTArel contral was 30.86%. 51% of the patients reached a ΔPTAabs of ≥ 10 dB. About 2 of 5 patients recovered to a ΔPTArel contral ≥ 50% or reached ≤ 10 dB of contralateral ear. The multivariate analysis revealed that an ISSNHL on the left side [Hazard ratio (HR) = 1.6.88; confidence interval (CI) = 1.161-2.454], no down-sloping audiogram type (HR = 2.016; CI = 1.391-2.921), and no prior outpatient prednisolone treatment (HR = 2.374; CI = 1.505-3.745) were independent factors associated with better recovery (ΔPTAabs ≥ 10 dB). CONCLUSION: Inpatient treatment of ISSNHL is variable in daily practice. The population-based recovery rate was worse than reported in clinical trials. More standardization and clearer criteria for outpatient, inpatient, and salvage therapy are needed.

Inpatient Treatment of Patients Admitted for Dizziness: A Population-Based Healthcare Research Study on Epidemiology, Diagnosis, Treatment, and Outcome.

OBJECTIVE: To determine inpatient treatment rates of patients with dizziness with focus on diagnostics, treatment and outcome. STUDY DESIGN: Retrospective population-based study. SETTING: Inpatients in the federal state Thuringia in 2014. PATIENTS: All 1,262 inpatients (62% females, median age: 61 yr) treated for inpatient dizziness were included. MAIN OUTCOME MEASURES: The association between analyzed parameters and probability of improvement and recovery was tested using univariable and multivariable statistics. RESULTS: Final diagnosis at demission was peripheral vestibular disorder (PVD), central vestibular disorder (CVD), cardiovascular syndrome, somatoform syndrome, and unclassified disease in 75, 9, 3, 0.6, and 13%, respectively. The most frequent diseases were acute vestibular neuritis (28%) and benign paroxysmal positional vertigo (22%). The follow-up time was 38 ±â€Š98 days. 88.5% of patients showed at least an improvement of complaints and 31.4% a complete recovery. The probability for no improvement from inpatient dizziness was higher if the patient had a history of ear/vestibular disease (hazard ratio [HR] = 1.506; 95% confidence interval [CI] = 1.301-1.742), and was taking more than two drugs for comorbidity (HR = 1.163; CI = 1.032-1.310). Compared with final diagnosis of cardiovascular syndrome, patients with PVD (HR = 1.715; CI = 1.219-2.415) and CVD (HR = 1.587; CI = 1.076-2.341) had a worse outcome. CONCLUSIONS: Inpatient treatment of dizziness was highly variable in daily practice. The population-based recovery rate was worse than reported in clinical trials. We need better ways to implement clinical trial findings for inpatients with dizziness.

[Direct Microlaryngoscopy: A Population-Based Analysis on Outcome, Complications and Surgery Rates]. / Mikrolaryngoskopie: Eine populationsbezogene Analyse zu Outcome, Komplikationen und Operationsraten.

Although microlaryngoscopy is an integral part of surgical routine of otorhinolaryngologists, there is no population-based data published on surgery rates and efficiency of microlaryngoscopy country-wide or nation-wide. All 616 patients who underwent microlaryngoscopy 2011 in one of the eight ENT departments in Thuringia were analyzed according to patients' characteristics, therapy, complications and follow-up. The majority of admissions were performed because of a benign disease (60%) of the larynx, and in 33% related to a malignant disease or suspicion of a malignant disease. When a benign disease was suspected, it was confirmed 98% of cases. When a malignant tumor was suspected, it was confirmed in 51% of cases, i. e. ruled out in 49% of cases. Transient laryngeal edema (22%) and bleeding needing revision surgery (1%) were the most frequent or serve observed postoperative sequelae. Teeth damage occurred only in 2 cases (0.2%). A recurrence of the primary disease was observed in 14%. Longer surgery time was an independent predictor for postoperative bleeding and for postoperative laryngeal edema (p=0.050 and p=0.013, respectively). Revision surgery (p<0.0001) and a final diagnosis of a malignant disease (p=0.017) were independent predictors for recurrence of the primary disease. The overall incidence of microlaryngoscopy was 22.98/100000 population. The highest incidence was seen for patients 50-59 years of age with 39.76/100000. Benign diseases were the most frequent indication with 19.33/100000. This population-based analysis is showing that microlaryngoscopy is performed effectively and with low postoperative risks in daily routine of otorhinolaryngologists.

Pediatric adenoidectomy: a population-based regional study on epidemiology and outcome.

OBJECTIVES: To evaluate population-based data on incidence of pediatric adenoidectomy and rate of revision surgery. METHODS: A retrospective study of all adenoidectomies in children was performed in the year 2009 in all otolaryngology departments in one federal state, Thuringia, in Germany. Patients' characteristics, preoperative diagnostics and postoperative complications were analyzed. The association between baseline characteristics and the risk of re-adenoidectomy was examined using Kaplan-Meier method with univariate log-rank test, and with a multivariate Cox regression model. Population data were used to calculate age-related annual rates of adenoidectomies. RESULTS: 1939 adenoidectomies were performed in 2009 in Thuringia. 89% were primary cases and 11% of the children already had an adenoidectomy prior to 2009. Immediate re-surgery because of primary hemorrhage was necessary in 0.8% of the cases. Re-adenoidectomy because of recurrent symptoms was needed in 9% of patients after a median interval of 16 months. The univariate analysis showed that the factors age ≤3 years and primary surgery were significantly associated to a higher risk of surgery because of recurrent symptoms The multivariate analysis showed that primary surgery was independently associated with the risk of re-surgery (hazard ratio 1.66; 95% confidence interval 1.01-2.74). The annual adenoidectomy rate was 678/100,000 underage habitants. The incidence was highest between 2 and 4 years of age. CONCLUSIONS: This population based analysis is showing that adenoidectomy is performed country-wide with good results and low risk on important scale in daily routine by otorhinolaryngologists. The risk of re-adenoidectomy seems to be higher than hitherto reported by hospital-based studies.

Middle ear surgery in Thuringia, Germany: a population-based regional study on epidemiology and outcome.

OBJECTIVE: To evaluate population-based data on incidence and efficiency of middle ear surgery. STUDY DESIGN: Retrospective review. SETTING: All otolaryngology departments in one federal state in Germany. PATIENTS: All 1,037 middle ear surgeries performed in Thuringia in 2005. INTERVENTIONS: Middle ear surgery. MAIN OUTCOME MEASURE: Analysis of preoperative and postoperative audiometric results, preoperative diagnostics, and postoperative complications. Univariate statistical tests were used to analyze predictors for air-bone gap (ABG) improvement, complications, and need for resurgery. Population data were used to calculate incidences of middle ear diseases admitted for surgery and annual rates of middle ear surgeries. RESULTS: ABG improved after surgery for chronic otitis media without and with cholesteatoma, otosclerosis, trauma cases, or complication after acute otitis media/externa (p < 0.0001; p < 0.0001; p < 0.0001; p = 0.005; p = 0.004; respectively). Middle ear surgery significantly improved bone conduction in cases of otosclerosis (p = 0.008), sudden deafness (p = 0.006), and acute otitis media/externa with complication (p = 0.004). There was a trend of more complication in patients older than 60 years (p = 0.055). Surgery was indicated for chronic otitis media without cholesteatoma in 17.4/100,000 persons, for cholesteatoma in 15.0/100,000, for otosclerosis in 5.7/100,000, for sudden deafness with suspicion of perilymph fistula in 1.5/100,000, and for trauma with affection of the lateral cranial base and hearing loss or otitis media with complication in 1.3/100,000 habitants, respectively. A cochlear implant was indicated in 1.0/100,000 habitants. CONCLUSION: This population based analysis is showing that middle ear surgery is performed country-wide with good results and low risk on important scale in daily routine by ear surgeons.

Gastroesophageal reflux disease (GERD), extraesophageal reflux (EER) and recurrent chronic rhinosinusitis.

Chronic polypoid rhinosinusitis (CRS) is a common disease, affecting approximately 16% of the adult population in the US every year. In addition to many well known predisposing factors, an association with reflux disease is hypothesized. Such an association might explain the recurrence of polyposis in the face of improved surgical techniques and postsurgical treatment of CRS. At present it is unclear whether extraesophageal reflux directly injures the sinus mucosa, whether gastroesophageal reflux leads to vagus-mediated neuroinflammatory changes, or whether both mechanisms occur separately or simultaneously. In patients suffering from recurrent CRS (n=20) and healthy volunteers (n=20), ambulatory 24 h two channel pH testing was performed. The number of reflux events, the fraction of the total time during which pH was below 4, and the reflux area index (RAI) were determined in the esophagus as well as in the hypopharynx. Patients with recurrent CRS had significantly more reflux events in the esophagus and the fraction of pH<4 and the RAI were increased up to 10-fold compared to healthy volunteers. In contrast to the esophagus, these differences were not observed in the hypopharynx. Recurrent CRS is often associated with GERD but not with EER. Recurrent disease or prolonged recovery after surgery should raise the suspicion of reflux disease as a possible triggering factor. Because GERD itself cannot be diagnosed by laryngoscopy, and because of the subjectivity of symptoms such as heartburn, the otolaryngologist should consider double-probe pH testing as the diagnostic procedure of choice.

Use of interferon-alpha in recurrent respiratory papillomatosis: 20-year follow-up.

OBJECTIVES: The aim of this study was analysis of the results of use of interferon-alpha (IFN-alpha) in patients with recurrent respiratory papillomatosis (RRP) and correlation of the results with human papillomavirus (HPV) type. METHODS: A multicenter prospective series (42 patients from 22 hospitals) yielded 20 years of follow-up of patients with RRP and HPV typing who were treated with IFN-alpha in doses of 3 MU/m2 3 times per week. RESULTS: During long-term follow-up (mean +/- SD, 172 +/- 36.8 months), the rate of event-free survival evaluated by Kaplan-Meier analysis was 42.8%, and the overall survival rate was 82.6%. The HPV typing revealed an association of HPV 11 with a more aggressive disease course (64% of HPV 11 patients versus 24% of HPV 6 patients), a lower incidence of long-term response to IFN-alpha therapy (14% of HPV 11 patients versus 64% of HPV 6 patients), and a higher incidence of malignant transformation and mortality during follow-up (36% and 24%, respectively, of HPV 11 patients versus 0% of HPV 6 patients). CONCLUSIONS: The obtained results revealed maximal effectiveness of IFN-alpha therapy in RRP patients with HPV 6 as compared with HPV 11. The association of HPV 11 with a worse long-term response to IFN-alpha therapy and a higher incidence of malignant transformation and mortality is clinically important and indicates the necessity of HPV typing in RRP patients after the first biopsy.

Extraesophageal reflux and upper aerodigestive tract diseases.

Reflux disease can cause multiple disorders not only of the esophagus but also of the upper aerodigestive tract. In the last decade, an association between reflux disease and multiple head and neck diseases was described, including those of the larynx and pharynx as well as those of the nose, the sinuses and the middle ear. The present article summarizes these different diseases and possible pathomechanisms are explained. In particular, there is a need to differentiate between the classical gastroesophageal reflux disease (GERD) and the extraesophageal manifestation of the reflux disease, called extraesophageal reflux (EER). Both diseases are characterized by different symptoms and can cause different disorders. To differentiate between GERD and EER, double-probe pH monitoring is mandatory. At last, some aspects of reflux therapy are explained.

Cerebrospinal fluid leaks of temporal bone origin: etiology and management.

BACKGROUND: Cerebrospinal fluid (CSF) leaks of the temporal bone region require surgical treatment as they pose life-threatening risks such as meningitis. AIM: The aim of the study was to determine the surgical outcome depending on different operation techniques and grafts. METHOD: We performed a retrospective review of 28 cases of CSF leaks, operated in our department from 1983 to 2002. After a mean follow-up of 8 years, patients were interviewed concerning otorrhea or rhinorrhea and meningitis. In this context, our management of CSF leaks is presented. RESULTS: The CSF leak had arisen spontaneously (n = 3), traumatically (n = 6) or postoperatively (n = 19). The surgical CSF leak repairs were performed via a transmastoid (n = 13), a middle fossa (n = 11) or a combined (n = 4) approach. Surgical outcome was independent on the used graft. CSF leak could be sealed in 25 of 28 cases. Only 3 patients suffered from recurrences. Meningitis or other complications did not occur. CONCLUSIONS: Comparing different techniques and grafts, there were no differences in the surgical outcome.

Nasal teeth associated with rhinosinusitis.

Intranasal ectopic dentition is a rare clinical entity. It may be asymptomatic or can be associated with different symptoms. In 25% of the reported cases an association with rhinosinisitis is suspected. The possible pathophysiology, diagnosis and treatment are discussed. Teeth in the floor of both nasal cavities, associated with chronic rhinosinusitis, are reported for the first time, and a new treatment option of endonasal extraction under microscopic control is presented.
