Comparison of superelastic nitinol stapes prostheses and platin teflon stapes prosthesesAbstractIntroduction
Stapes plasty is an established procedure to improve hearing in case of otosclerosis. By reinforcing the prostheses, an optimization of the prosthesis could be achieved. The aim of the study was to evaluate the audiological results of the Nitinol Superelastic stapes prosthesis compared with a Platin–Teflon prosthesis.
Material and methods
In a retrospecitve setting, the audiological results of nine patients who have been implanted with a Nitinol Alloy Superelastic stapes prothesis were compared with the results of ten patients, which have been implanted with a Platinum–Teflon piston prostesis. All operations were performed by the same experienced ear surgeon.
Results
The Nitinol-group presented an average of postoperative air–bone-gap over all frequencies (0.5–6 kHz) of all patients of 15.1 dB. In the Platin–Teflon group, the average of postoperative air–bone-gap was 14.9 dB. Moreover, the post surgery delta–bone-conduction pre- to post surgery showed no differences (0.5–6 kHz). There were no surgical complications in both groups.
Conclusion
Based on the patient collective, stapes plasty using a Nitinol Superelastic stapes prosthesis is a sufficient method for improving the hearing conduction.
Design
Retrospective case series.
Setting
University Department.

Evaluation of the information given to patients undergoing total pharyngolaryngectomy and quality of life: a prospective multicentric studyAbstractBackground
Providing cancer patients with adequate information is essential to their confidence and satisfaction regarding medical care. The aims of this study were to evaluate the information given to patients undergoing total pharyngolaryngectomy (TPL) as well as the evolution and predictors of patient quality of life (QoL).
Methods
We conducted a prospective multicentric study on patients undergoing TPL for a locally advanced laryngeal/hypopharyngeal cancer. All patients completed the EORTC QLQ-INFO25, QLQ-C30, and QLQ-H&N35 questionnaires, before and after surgery.
Results
This study enrolled 46 patients. Between the pre- and post-therapeutic periods, we observed no significant changes in the global QLQ-INFO25 and QLQ-C30 scores. However, we found a significant deterioration in 4 QLQ-INFO25 scales/items and in social functioning, as well as an increase of sense, speech, and social contact problems. N-stage and professional activity were significant predictors of preoperative QLQ-INFO25 scores. Younger age was significantly associated with financial difficulties, whereas professional activity and lower education level were significant predictors of xerostomia and swallowing problems, respectively.
Conclusion
In patients undergoing TPL, we observed significant changes in QLQ-INFO25 scores between the pre- and post-treatment periods and, particularly, a deterioration of patient satisfaction with the information received. Several clinical factors were identified as significant predictors of QLQ-INFO25 and QoL scores.

Do changing trends in tonsil surgery affect hemorrhage rates? A longitudinal study covering 1,452,637 proceduresAbstractPurpose
To evaluate whether changing trends in tonsil surgery between 2005 and 2017 in Germany were associated with different age- and gender-specific hemorrhage rates.
Methods
A longitudinal population-based inpatient cohort study was performed including all patients who had undergone tonsillectomy (with or without adenoidectomy), tonsillotomy, abscess-tonsillectomy, removal of tonsillar remnants and surgical treatment to achieve hemostasis following tonsil surgery. The population was stratified by age (groups of 5 years) and gender. Operation rates were calculated in relation to the end-year population number according to the German Federal Office of Statistics.
Results
The surgical rates per 100,000 had significantly decreased from 170.39 to 90.95 (46.62%) in female patients and from 147.33 to 88.19 (40.14%) in male patients within the study period (p < 0.001). A total of 42.352 female patients had required surgical treatment to achieve hemostasis following 783,005 procedures (5.41%). In contrast, only 669,632 operations were performed in male patients but were complicated by hemorrhage in 51.185 cases (7.64%) which was significantly different (p < 0.001). The male-to-female ratio of the surgical rates had increased from 0.86:1 to 0.93:1. Hemorrhage rates differed significantly between age groups (p < 0.001). Male gender is a significant risk factor for bleeding at all ages < 85 years with greatest differences in 20- to 25-year-old patients (12.19% male vs. 6.26% female).
Conclusions
Changing trends in tonsil surgery are not associated with increased rates of bleeding complications. Hemorrhage following tonsil surgery is significantly related to age and gender and this should be noted when reported hemorrhage rates in the literature are appraised by the reader.

Hospital admissions for acute throat and deep neck infections versus tonsillectomy rates in GermanyAbstractPurpose
To evaluate trends in hospital admissions in Germany for acute infections of the upper airway and deep neck in the context of the number of tonsil-related surgical procedures between 2005 and 2017.
Methods
A retrospective longitudinal population-based cohort study was performed including all unplanned admissions for acute pharyngitis/tonsillitis, abscess formation of the peritonsillar or retropharyngeal/parapharyngeal space. Elective procedures included tonsillectomy (with or without adenoidectomy), secondary tonsillectomy, and tonsillotomy. Emergency operations encompassed abscess-tonsillectomy and transoral drainage procedures of the peritonsillar/parapharyngeal/retropharyngeal space.
Results
553.600 admissions were registered in total with a significant, stepwise increase between 2005 and 2017, including retropharyngeal/parapharyngeal abscess (47.0%), acute tonsillitis (30.8%), acute pharyngitis (26.5%) and peritonsillar abscess (7.9%). There were 1.323.984 elective operations with a significant decrease during the study period. A total of 188.316 emergency operations were done, a significant decrease in the number of abscess-tonsillectomies was compensated by the increased number of transoral peritonsillar abscess drainages. The number of transoral parapharyngeal and retropharygeal abscess drainage procedures did not change significantly (p = 0.846; p = 0.846). Negative correlation was significant between admissions for chronic tonsillitis and emergency admissions (Pearson correlation coefficient = − 0.879, p < 0.001) and also between elective and emergency operations (r = − 0.667; p = 0.013).
Conclusions
Concerning infections of the upper airway and deep neck spaces, German Hospitals have to prepare strategies for the increasing challenge by unplanned admissions and emergency operations. Further research is required to clarify whether this phenomenon is caused by the significant decrease in the number of elective operations.

Assessment of the cancerization risk for oral potentially malignant disorders by clinical risk model combined with autofluorescence and brush biopsy with DNA-image cytometryAbstractPurpose
To explore the feasibility of assessing the cancerization risk of oral potentially malignant disorders (OPMD) through a clinical risk model combined with autofluorescence and brush biopsy with DNA-image cytometry.
Methods
We collected the baseline clinical data of 269 patients; then, performed autofluorescence, brush biopsy with DNA-image cytometry and histopathological examination. Then, we obtained the significant factors by univariate logistic analysis, constructed the clinical risk model by multiple logistic regression and selected the optimal cutoff value according to the maximum Youden index. Finally, we calculated the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of the clinical risk score ≥ cutoff value, autofluorescence and brush biopsy with DNA-image cytometry, and plotted the receiver-operating characteristic (ROC) curves and decision curve analysis (DCA).
Results
The clinical risk model is represented by the formula: 1 × gender + 1.6 × age group + 1 × lesion site + 1.4 × local stimulus + 1.5 × drink. The area under the curve (AUC) was 0.83, and the optimal cutoff score was 3. The AUC indicated that the clinical risk score ≥ 3 (0.74) and autofluorescence (0.77) had a certain diagnostic values, while brush biopsy with DNA-image cytometry (0.92) displayed a good value. Besides, the DCA showed that all three tests had clinical significance.
Conclusions
The cancerization risk of patients can be assessed by the clinical risk model combined with sequence application of autofluorescence and brush biopsy with DNA-image cytometry, to decide whether histopathological examination or other intervention measures should be selected.

A prospective, feasibility study to evaluate the efficacy and usability of a novel drivable endoscope in patients with chronic rhinosinusitisAbstractPurpose
To carry out a pilot study to evaluate the efficacy of a novel, drivable endoscope (the Peregrine™ Drivable ENT Scope), compared to standard rigid endoscopes in the access, visualization, and irrigation of the paranasal sinus anatomy.
Methods
A prospective, multi-center, feasibility study was conducted on seventeen subjects who underwent primary functional endoscopic sinus surgery and were evaluated with the drivable endoscope and standard, rigid endoscopes (0°, 30° and 70°, as applicable). A CT scan was available for image guidance, as needed. The primary efficacy endpoint was the ability to access and visualize sinonasal anatomic landmarks. Secondary endpoints included device usability, as measured by a usability questionnaire given to surgeons postoperatively; the device’s ability to irrigate the sinuses and patient reports of tolerability and pain during postoperative procedures.
Results
The drivable endoscope success rate in visualizing all paranasal sinus anatomic landmarks was 55.6% better than the standard rigid endoscopes: 98.3% (178/181) versus 42.7% (76/178); p < 0.001. Surgeons rated scores of over 4 (on a 1–5 scale) for the usability of the drivable endoscope to enter the maxillary, frontal and sphenoid sinuses. The ability to irrigate the sinuses using the drivable endoscope was given a mean score of 4.3, and image quality was given a mean score of 3.4. The three patients evaluated postoperatively reported low pain and high tolerability scores with the drivable endoscope.
Conclusions
These preliminary results indicate that the drivable endoscope is effective, easy to use and highly tolerable in sinonasal endoscopy.
