Determinants influencing cholesteatoma recurrence in daily practice: a retrospective analysis.

BACKGROUND: Cholesteatoma is a benign but destructive epithelial lesion in the middle ear and/or mastoid. It is hard to translate data from previous research to daily clinical practice. In this study, factors influencing recurrence rates in daily clinical practice were identified. METHOD: The study included 67 patients who were treated for a cholesteatoma with combined approach tympanoplasty. The average follow-up time was 35 months. RESULTS: The recurrence rate was 23.3 per cent in adults and 45.5 per cent in children. Predictors of recurrence were younger age and a low tegmen. A cholesteatoma in a child and the simultaneous presence of a low tegmen led to recurrence in 82.8 per cent of the patients. CONCLUSION: Patients - especially children - with a low tegmen have an increased risk of recurrence. It is recommended that ENT surgeons be aware of recurrence in children, particularly in the case of a low tegmen.

A comparison of international clinical practice guidelines on adult chronic rhinosinusitis shows considerable variability of recommendations for diagnosis and treatment.

OBJECTIVES: To compare international clinical practice guidelines on adult chronic rhinosinusitis (CRS). DESIGN: Extensive literature search in Embase, PubMed and the internet (Google, websites of well-known guideline organizations) on November 21st 2018. MAIN OUTCOME MEASURES: Guidelines' quality was measured by the AGREE II instrument. A summary and comparison of recommendations on diagnosis and treatment with harmonized levels of evidence (LoE) and grade of recommendations (GoR) is given. RESULTS: We selected ten guidelines on CRS. Five guidelines were of sufficient to high quality according to AGREE II, the remaining guidelines predominantly did not meet AGREE II criteria. We harmonized all guideline recommendations so we could compare them, although three guidelines did not provide a LoE. Five guidelines provided recommendations on diagnosis, all of them recommended performing nasal endoscopy, CT scan and allergy testing (with varying GoRs). All ten guidelines provided recommendations on therapy, one treatment, i.e., the use of intranasal steroids, was recommended by all guidelines (with varying GoRs). Recommendations for surgical treatment of CRS were provided by five guidelines. CONCLUSION: We performed an extensive search and included ten (inter)national guidelines on CRS for adults. According to AGREE II, five were of good or sufficient quality. Overall, there was much variation between guidelines in recommended diagnostic test or treatment, direction of evidence and GoR. We found consensus for nasal endoscopy, CT scan, allergy testing and intranasal steroids. We argue for standardization of guideline development, to increase their quality and improve comparability.

Otolaryngologists adhere to evidence-based guidelines for chronic rhinosinusitis.

PURPOSE: To assess awareness of, opinion about and adherence to evidence-based guidelines on chronic rhinosinusitis among Dutch Otolaryngologists. METHODS: We assessed implementation of two guidelines, one Dutch and one European, that are both intended for diagnosis and treatment of patients with chronic rhinosinusitis. We invited 485 Otolaryngologists to fill out a questionnaire and report on their opinion on and adherence to the guidelines. The adherence was further tested by 4 clinical case scenarios, derived from guideline recommendations. RESULTS: 166 (34%) completed the questionnaire. 99% of the respondents was aware of one or both guidelines. Most respondents (90%) consider the guidelines as directing or supportive for their clinical practice based on the clinical case scenarios, between 62 and 99% of the respondents act according to guidelines. Concerning diagnosis, CT-imaging is performed more and allergy testing less than recommended. Where multiple treatment options are recommended, the responses are more heterogeneous as a result of this. Nonetheless, high recommended treatment was chosen more often. Otolaryngologists were reluctant in surgical treatment as a first option, which is according to the guidelines. CONCLUSIONS: Overall, both the EPOS and CBO guideline are well known among Dutch Otolaryngologists and 90% indicates that the guideline is important in their daily practice. Adherence to the guidelines is sufficient to high. If multiple treatment or diagnostic options are recommended this leads to a more heterogeneous response pattern. Recommendations with a high grade of recommendation were followed up most often.

Quality of life questionnaires in otorhinolaryngology: a systematic overview.

BACKGROUND: The importance of quality of life (QOL) as an endpoint and the use of validated QOL questionnaires have increased over time. OBJECTIVES: To evaluate health-related quality of life (HR-QOL) measurement instruments used in patients in otorhinolaryngology (ORL). We aimed to establish the use of QOL questionnaires in ORL over a period of time, establish the use of QOL questionnaires within different domains and determine the use of validated QOL questionnaires. MAIN OUT COME MEASURES: We performed a comprehensive search in PubMed up to 1 January 2014. Articles were included that measured HR-QOL questionnaires in clinical practice in children, adolescents or adults in 42 journals of ORL. Multiple unique QOL questionnaires, organised according to domain, time and survey of validation, were extracted from reported articles. RESULTS: Of 2442 articles, we utilised 1196 publications with a total of 2103 QOL questionnaires regarding ORL. We evaluated a variety of 363 unique QOL questionnaires in which 60% (n = 220) QOL questionnaires had been validated. We found a continuing increase in the amount of articles which used QOL questionnaires since the beginning of the 20th century, while the percentage of validated QOL questionnaires remained the same (76%). Most QOL questionnaires were used in the domains oncology (35%), otology (21%) and rhinology (20%). The domain otology had the largest amount of unique QOL questionnaires (n = 122). CONCLUSIONS: We identified and evaluated all unique HR-QOL questionnaires utilised in patients in ORL. Recently, the use of validated and non-validated HR-QOL questionnaires has increased within all domains of ORL. The assessment of QOL has become an important outcome measure in clinical practice, in medical research and for healthcare organisations.

The value of postoperative anticoagulants to improve flap survival in the free radial forearm flap: a systematic review and retrospective multicentre analysis.

BACKGROUND: Free radial forearm flap (FRFF) reconstruction is a valuable technique in head and neck surgery, which allows closure of large defects while striving to maintain functionality. Anticoagulative drugs are often administered to improve flap survival, although evidence regarding effectiveness is lacking. OBJECTIVE OF REVIEW: To investigate the effectiveness of postoperative anticoagulants to improve survival of the FRFF in head and neck reconstruction. TYPE OF REVIEW: Systematic review and multicentre, individual patient data meta-analysis. SEARCH STRATEGY: MEDLINE, EMBASE, Web of Science and CINAHL were searched for synonyms of 'anticoagulants' and 'free flap reconstruction'. EVALUATION METHOD: Studies were critically appraised for directness of evidence and risk of bias. Authors of the highest quality publications were invited to submit their original data for meta-analysis. RESULTS: Five studies were of adequate quality, and data from four studies (80%) were available for meta-analysis, describing 759 FRFF procedures. Anticoagulants used were as follows: aspirin (12%), low molecular weight dextran (18.3%), unfractioned heparin (28.1%), low molecular weight heparin (49%) and prostaglandin-E1 (2.1%). Thirty-one per cent did not receive anticoagulants. Flap failure occurred in 40 of 759 patients (5.3%) On univariate analysis, use of unfractioned heparin was associated with a higher rate of flap failure. However, these regimens were often administered to patients who had revision surgery of the anastomosis. In multivariate logistic regression analysis, anticoagulant use was not associated with improved flap survival or flap-related complications. CONCLUSIONS: The studied anticoagulative drugs did not improve FRFF survival or lower the rate of flap-related complications. In addition, some anticoagulants may cause systemic complications.

Guidelines in head and neck oncology compliance and consequences of deviations from the standard protocol for tongue and floor of mouth squamous carcinoma.

OBJECTIVES: To investigate the extent of violation of a regional guideline for the treatment of patients with carcinoma of the tongue/floor of mouth (ICD0 C02, C04). Different aspects of protocol violation (i.e. undertreatment or overtreatment) and consequences for treatment outcome were evaluated. DESIGN: Retrospective analysis of data from medical records. SETTING: The Department of Maxillofacial and Oral Surgery and the Department of Otorhinolaryngology and Head and Neck Surgery of the University Medical Centre Utrecht. PARTICIPANTS: A total of 217 patients treated between 1991 and 2001 for a stage II and stage III carcinoma of the tongue/floor of mouth. MAIN OUTCOME MEASURES: Protocol violation, tumour recurrence. RESULTS: The overall adherence to the guideline was 55%. In the non-adherence group of patients, 21% were overtreated, 71% were undertreated, and 8% were both overtreated and undertreated. There was no statistically significant difference in tumour recurrence between the two groups for stage II (P=0.68) or stage III (P=0.97) disease, or between undertreatment and overtreatment of patients with stage II (P=0.47) or stage III (P=0.90) disease. CONCLUSIONS: Although protocol violation occurs in as many as 45% of patients, this does not result in a worse tumour recurrence. Neither overtreatment nor undertreatment appears to affect the overall tumour recurrence.
