Sinonasal inverted papilloma and predictors of health-related quality of life after endonasal endoscopic surgery: A prospective cohort study.

OBJECTIVES: Existing knowledge on health-related quality of life (HRQoL) after surgical removal of sinonasal inverted papilloma (IP) is limited. Moreover, predictors for a better or worse post-operative HRQoL outcome are not known. Our aim was to assess HRQoL in all three health domains (physical, psychological, and social), track its post-operative trajectory, investigate if pre-operative observations could predict distinct post-operative HRQoL outcomes, and evaluate whether physicians' interventions could contribute to improved post-operative HRQoL. DESIGN: Prospective cohort study. SETTING: Tertiary referral hospital. PARTICIPANTS: Seventy-four patients who underwent surgery for an IP were included. They were asked to fill in the Endonasal Endoscopic Sinus and Skull-Base Surgery Questionnaire (EES-Q) pre-operatively, and then 2 weeks, 3 months, and 1 year post-operatively. MAIN OUTCOME MEASURES: Linear mixed models analyses were performed to evaluate the overall post-operative HRQoL and the separate health domains, as well as the impact of specific variables (sex, age, American Society of Anaesthesiologists [ASA] classification, smoker, Krouse staging, pre-operative EES-Q score, type of surgery, and post-operative antibiotics) on HRQoL improvement. RESULTS: The total EES-Q score (p < .001) as well as the physical (p < .001), psychological (p = .049), and the social (p = .002) domains significantly improved post-operatively. ASA classification (p = .049), pre-operative EES-Q score (p < .001) and post-operative antibiotics (p = .036) were significant variables. CONCLUSIONS: Overall HRQoL, as well as each of the three health domains, improved significantly. A higher ASA score, a higher pre-operative EES-Q score, and the administration of post-operative antibiotics were significant predictors for better HRQoL recovery post-operatively. Further research is necessary to confirm these results.

Prospective evaluation of multidimensional health-related quality of life after endoscopic endonasal surgery for pituitary adenomas using the endoscopic endonasal sinus and skull base surgery questionnaire.

Objective: Social functioning is an important factor in the evaluation of postoperative health-related quality of life (HRQoL) for pituitary adenoma patients. In a prospective cohort study multidimensional HRQoL of non-functioning (NFA) and functioning (FA) pituitary adenoma patients were evaluated following endoscopic endonasal surgery using the endoscopic endonasal sinus and skull base surgery questionnaire (EES-Q). Methods: Prospectively, 101 patients were included. The EES-Q was completed preoperatively and postoperatively (2 weeks, 3 months, 1 year). Sinonasal complaints were completed daily during the first week postoperatively. Preoperative and postoperative scores were compared. A generalized estimating equation (uni- and multivariate) analysis was performed to identify significant HRQoL changes related to selected covariates. Results: Two weeks postoperatively, physical (p < .05) and social (p < .05) HRQoL are worse and psychological (p < .05) HRQoL improved compared with preoperatively. Three months postoperatively, psychological HRQoL (p = .01) trended back to baseline and no differences in physical or social HRQoL were reported. One year postoperatively, psychological (p = .02) and social (p = .04) HRQoL improved while physical HRQoL remained stable. FA patients report a worse HRQoL preoperatively (social, p < .05) and 3 months postoperatively (social, p < .02 and psychological, p < .02). Sinonasal complaints peak in the first days postoperatively and gradually return to presurgical levels 3 months postoperatively. Conclusions: The EES-Q provides meaningful information on multidimensional HRQoL to improve patient-centred health care. Social functioning remains the most difficult area in which to achieve improvements. Despite the relatively modest sample size, there is some indication that the FA group continues to show a downward trend (and thus improvement) even after 3 months, when most other parameters reach stability. Level of evidence: Level II-B.

Extending the use of the Endoscopic Endonasal Sinus and Skull Base Surgery Questionnaire in a cross-sectional study: Patients with chronic rhinosinusitis versus healthy controls.

OBJECTIVES: There are several instruments to assess health-related quality of life (HRQoL) in chronic rhinosinusitis (CRS). Unfortunately, none of them evaluates all three health domains (physical, social and psychological) important to assess the overall well-being of the patient. The Endoscopic Endonasal Sinus and Skull Base Surgery Questionnaire (EES-Q) does assess all these elements. Initially, the EES-Q is validated to evaluate the impact of endoscopic endonasal surgery (EES) on HRQoL. The aim of this study is to assess whether EES-Q outcomes differ in patients with CRS compared with healthy individuals. Therefore, extending the use of the EES-Q for all CRS patients. DESIGN: Cross-sectional study. SETTING: Tertiary referral hospital. PARTICIPANTS: One hundred patients with uncontrolled CRS (50% with nasal polyps) scheduled to receive EES. The questionnaire was completed preoperatively. Healthy control subjects (n = 100) without any history of sinusitis or a known current medical treatment at a hospital were included. MAIN OUTCOME MEASURES: Mann-Whitney U test was performed to identify differences in EES-Q scores (domain scores and EES-Q score). RESULTS: The median EES-Q score in CRS patients (33.8) was significantly higher (p < 0.001) than in the control group (10.4). As well as the physical (52.5 vs. 16.4, p < 0.001), psychological (13.8 vs. 5.0, p < 0.001) and social (37.5 vs. 2.5, p < 0.001) domain scores. CONCLUSIONS: With this study, we are extending the use of the EES-Q. It indicates that the EES-Q can be a valuable clinical tool to assess multidimensional HRQoL in all patients with CRS.

An aggressive lactotroph pituitary tumor in a young male: A pituitary carcinoma without metastasis.

This case report concerns a 31-year-old male with an aggressive pituitary tumor who presented initially with bitemporal hemianopsia and slightly elevated prolactin. On magnetic resonance imaging of the brain, there was a sellar mass with parasellar invasion to the lateral aspects of the internal carotid arteries, compressing the optic chiasm. On histopathological analysis, the diagnosis was made of a densely granulated lactotroph pituitary tumor with a Ki67 proliferation rate of 15%, a mitotic count of 6/10 high-power fields, and p53 positivity. Based on these features, the tumor was classified as a grade 2b tumor according to the Trouillas classification, and a more aggressive behavior of the tumor could be expected. In order to anticipate a future need for alternative drug treatments, the following analyses were undertaken: MGMT methylation (present) as well as the expression of estrogen receptor (negative), programmed-death ligand 1 (60 - 70% positive tumor cells), vascular endothelial growth factor-A and somatostatin receptor 2 (both positive). There was regrowth of residual tumor tissue, and the treatment consisted thus far of repeat surgery, cabergoline, pasireotide, and radiotherapy. Chemotherapy with temozolomide could not yet be initiated due to a concurrent infertility treatment. This case is unique because the tumor displays atypical characteristics, both in terms of morphology and behavior. It also illustrates how pathologists can play an important role in determining the diagnosis, prognosis, and possibilities for targeted therapy.

The effect of three-dimensional visualisation on performance in endoscopic sinus surgery: A clinical training study using surgical navigation for movement analysis in a randomised crossover design.

OBJECTIVES: Endoscopic imaging techniques and endoscopic endonasal surgery (EES) expertise have evolved rapidly. Only few studies have assessed the effect of three-dimensional (3D) endoscopy on endoscopic sinus surgery (ESS). The present study aimed to objectively and subjectively assess the additional value of 3D high-definition (HD) endoscopy in ESS. DESIGN: A randomized crossover study of endoscopic surgery performance, using five ESS tasks of varying complexity, performed on Thiel embalmed human specimens. SETTING: Simulated surgical environment. PARTICIPANTS: Thirty participants, inexperienced in ESS. MAIN OUTCOME MEASURES: Performance was assessed using video imaging, surgical navigation and questionnaires. Main outcome measures were as follows: efficiency (defined by time to task completion), distance covered inside the nose, average velocity towards target, accuracy (measured by error rate), and subjective assessment of endoscope characteristics. RESULTS: During ESS tasks, both efficiency and accuracy did not differ significantly between 2D HD and 3D HD endoscopy. Subjectively, imaging characteristics of the 3D HD endoscope were rated significantly better. CONCLUSIONS: ESS performance of inexperienced participants was not significantly improved by the use of 3D HD endoscopy during ESS tasks, although imaging characteristics of the 3D HD endoscope were rated significantly better. Surgical field characteristics and surgical techniques are likely to influence any additional value of 3D HD endoscopy.

Evaluation of the psychometric properties of the endoscopic endonasal sinus and skull base surgery questionnaire (EES-Q) in a prospective cohort study.

OBJECTIVES: The patients' perspective on health has become increasingly important when assessing treatment outcomes. Recently, the Endoscopic Endonasal Sinus and Skull Base Surgery Questionnaire (EES-Q) was developed to determine the impact of endoscopic endonasal surgery on health-related quality of life (HRQoL). The aim of this study was to evaluate the test-retest reliability, construct validity and responsiveness of the EES-Q. DESIGN: Prospective cohort study. SETTING: University Medical Center Groningen, tertiary referral hospital, the Netherlands. PARTICIPANTS: One hundred patients who underwent endoscopic endonasal surgery because of sinus or anterior skull base pathology. MAIN OUTCOME MEASURES: Test-retest reliability, construct validity and responsiveness. RESULTS: The EES-Q domains exhibited good test-retest reliability (ICC > 0.90). Construct validity was corroborated by significant positive and negative correlations between the EES-Q and the Sino-Nasal Outcome Test-22 (SNOT-22) and postoperative health status (P < 0.01) respectively. The correlation between the social EES-Q domain and the ability to move and perform usual activities (EuroQol-5D-3L [EQ-5D-3L]) was significant positive (P < 0.01). In patients with paranasal sinus pathology, the EES-Q was responsive to clinical change (Cohen's d = 0.6). CONCLUSION: The EES-Q is a reliable and acceptable responsive disease-specific HRQoL instrument. The expected construct validity of the EES-Q is supported by the results in this study. Inconveniences in social functioning had the greatest negative impact on postoperative health status rating. This reflects the importance of a multidimensional HRQoL assessment after EES. The results indicate that the EES-Q is a promising disease-specific tool for the HRQoL assessment after endoscopic endonasal sinus or anterior skull base surgery.

Development of the Endoscopic Endonasal Sinus and Skull Base Surgery Questionnaire.

BACKGROUND: The patients' perspective of health outcomes has become important input for assessing treatment effects. However, existing endoscopic endonasal surgery (EES) instruments are not fully aligned with the concept of health-related quality of life (HRQoL). A prospective cohort study was therefore conducted to develop a suitable quality-of-life tool to assess nasal morbidity after EES: the Endoscopic Endonasal Sinus and Skull Base Surgery Questionnaire (EES-Q). METHODS: The study included 300 patients: 207 with sinus pathology and 93 with anterior skull base pathology. The EES-Q was administered prior to surgery and postoperatively (2 weeks, 3 months, and 1 year). Psychometric instrument properties were tested and relevant health domains were formulated. Seventy-two items were generated by the conventional psychometric approach. An exploratory factor analysis was used to test construct validity. The optimal number of factors to retain was determined by using the eigenvalues-greater-than-1 rule and scree plot. Orthogonal varimax rotation was used to enhance interpretability. Internal consistency was assessed using the Cronbach α. RESULTS: The factor analysis yielded a 3-factor solution, representing physical, psychological, and social functioning. The final version of the instrument consisted of 30 items with a high internal consistency (>0.80) for all 3 HRQoL domains. CONCLUSIONS: The EES-Q is a comprehensive, multidimensional, disease-specific instrument. A distinguishing characteristic is that, apart from the physical and psychological domains, the EES-Q also encompasses a social domain. Understanding different HRQoL aspects in patients undergoing EES may help caregivers restore, improve, or preserve the patient's health through individualized care, which depends on identifying their specific needs.

Calculating nasoseptal flap dimensions: a cadaveric study using cone beam computed tomography.

We hypothesize that three-dimensional imaging using cone beam computed tomography (CBCT) is suitable for calculating nasoseptal flap (NSF) dimensions. To evaluate our hypothesis, we compared CBCT NSF dimensions with anatomical dissections. The NSF reach and vascularity were studied. In an anatomical study (n = 10), CBCT NSF length and surface were calculated and compared with anatomical dissections. The NSF position was evaluated by placing the NSF from the anterior sphenoid sinus wall and from the sella along the skull base towards the frontal sinus. To visualize the NSF vascularity in CBCT, the external carotic arteries were perfused with colored Iomeron. Correlations between CBCT NSFs and anatomical dissections were strongly positive (r > 0.70). The CBCT NSF surface was 19.8 cm(2) [16.6-22.3] and the left and right CBCT NSF lengths were 78.3 mm [73.2-89.5] and 77.7 mm [72.2-88.4] respectively. Covering of the anterior skull base was possible by positioning the NSF anterior to the sphenoid sinus. If the NSF was positioned from the sella along the skull base towards the frontal sinus, the NSF reached partially into the anterior ethmoidal sinuses. CBCT is a valuable technique for calculating NSF dimensions. CBCT to demonstrate septum vascularity in cadavers proved to be less suitable. The NSF reach for covering the anterior skull base depends on positioning. This study encourages preoperative planning of a customized NSF, in an attempt to spare septal mucosa. In the concept of minimal invasive surgery, accompanied by providing customized care, this can benefit the patients' postoperative complaints.

Epistaxis caused by a dural AV-fistula at the cribriform plate.

OBJECTIVES/HYPOTHESIS: A dural arteriovenous fistula (DAVF) with cortical venous reflux (CVR) is a dangerous neurovascular entity. A DAVF at the cribriform plate is typically silent until its inevitable presentation with intracranial hemorrhage. CASE SUMMARY: A 67-year-old male presented with severe epistaxis. Following unsuccessful conventional measures and a surgical exploration, a catheter angiography showed a DAVF at the cribriform plate, with its nidus extending into the nasal cavity. The DAVF was treated via a small craniotomy. CONCLUSION: In case of atypical or unexplained nosebleeds, the possibility of a DAVF or other neurovascular pathology should be excluded by MRI/MRA or catheter angiography.

Limited evidence for the effect of presurgical nasoalveolar molding in unilateral cleft on nasal symmetry: a call for unified research.

BACKGROUND: In the past two decades, presurgical nasoalveolar molding has been applied increasingly in the care of patients with a cleft to improve nasal symmetry and facilitate closure of the lip and secondary rhinoplasty. Many cleft centers do not apply presurgical molding, because its effect is disputed. This review aims to quantify the effect of nasal symmetry in the long term. METHODS: A systematic review of the literature with the intention of performing a meta-analysis was performed. The search terms "cleft" AND ("molding" OR "moulding") were used in three databases. Twelve studies met the following inclusion criteria: (1) participants were humans with nonsyndromic unilateral cleft; (2) data concerning the effect of nasoalveolar molding on symmetry of the nose are reported or can be deduced; (3) article was written in English, German, or Dutch. RESULTS: The heterogeneity of the study designs, outcome variables, outcome variable expressions, follow-up periods, and inadequate data reporting made it impossible to calculate effect sizes and to perform a meta-analysis. All studies had a low Grading of Recommendations Assessment, Development and Evaluation level. Five studies reported exclusively positive effects on nasal symmetry, six studies reported mixed effects, and one study reported exclusively no effects. CONCLUSIONS: Results of studies of nasoalveolar molding are inconsistent regarding changes in nasal symmetry; however, there is a trend toward a positive effect. Studies concerning nasoalveolar molding in unilateral cleft lip, jaw, and palate are heterogeneous and lack adequate reporting. Recommendations for future research were provided to construct a consensus about the effect of nasoalveolar molding. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Unilateral hyperlucent lung in a child caused by a foreign body identified with v/q scintigraphy.

A 5-year-old girl presented with episodes of coughing, inspiratory stridor, and occasionally squeaking breath sounds. There was no history of a foreign body aspiration. Initially, she was diagnosed with allergic asthma. However, signs and symptoms continued despite a trial of inhaled corticosteroids. A chest radiograph showed a hyperlucent right lung, mainly in the upper lobe, with decreased vascular markings compatible with Swyer-James-MacLeod syndrome, or foreign body aspiration. V/Q imaging showed markedly diminished right lung ventilation and perfusion, especially in the upper lobe, with a hot spot in the area of the right bronchus. At bronchoscopy, a pistachio nutshell was removed from the right main bronchus.

Cranialization of the frontal sinus--the final remedy for refractory chronic frontal sinusitis.

OBJECT: Chronic sinusitis can be a debilitating disease with significant impact on quality of life. Frontal sinusitis has a relatively low prevalence, but complications can be severe due to its anatomical location. After failure of conservative measures, typically endoscopic procedures are performed to improve the drainage of the frontal sinus. The cranialization of the frontal sinus is the final surgical measure, in which the affected frontal sinus is truly removed. In this study the authors describe the surgical technique of cranialization of the frontal sinus for refractory chronic frontal sinusitis, systematically search the literature for its application, and assess patient satisfaction in a cohort of consecutively treated patients after long-term follow-up. METHODS: A consecutive cohort of 15 patients with refractory chronic frontal sinusitis was treated by cranialization of the frontal sinus and followed over a 20-year period (1989-2008) for the direct results and complications of the surgery. Long-term follow-up (mean 6.5 years) was obtained to assess the long-term effects of the cranialization. RESULTS: In all patients the signs and symptoms of chronic frontal sinusitis responded very well to the cranialization. Five patients had surgical complications, of which 2 were serious. One patient died of an unrelated cause and 1 patient was lost to follow-up. The remaining 13 patients had a long-term follow-up, which revealed that 12 of them thought that their life was better after the surgical procedure. CONCLUSIONS: Cranialization of the frontal sinus deserves consideration as the final remedy for refractory chronic frontal sinusitis after definite failure of other options.

Communicative abilities in toddlers and in early school age children with cleft palate.

OBJECTIVES: Evaluation of improvement in communicative abilities in children with nonsyndromic cleft palate. METHODS: Longitudinal retrospective case history study. Out of 117 children with cleft lip and/or cleft palate born in 1998, 1999 and 2000 and enrolled in the cleft palate team of the University Medical Centre Groningen (UMCG), 63 children were included in the study; 29 (46%) boys and 34 (54%) girls. From these 63 Dutch speaking children communicative abilities were measured when toddlers and at early school age. Cleft types were cleft lip with or without cleft alveolus (CL+/-A; n=10, 5%), unilateral cleft lip and palate (UCLP; n=23, 37%), bilateral cleft lip and palate (BCLP; n=9, 14%) and isolated cleft palate (CP; n=21, 33%). The percentage of problems in language comprehension, language production, articulation, hearing and hypernasality, present when toddlers, were compared with the percentage of problems found at early school age. The treatments executed were also analysed. RESULTS: Except for hearing problems, problems in all other communicative fields improved significantly. In the total group language comprehension problems decreased from 23% to 2% (p=0.00), language production problems from 21% to 6% (p=0.01), articulation problems from 57% to 25% (p=0.00) and hypernasality from 38% to 10% (p=0.04). Hearing problems appeared more difficult to treat effectively, they decreased from 42% to 31% (p=0.29). Children with BCLP appeared to have the most problems, followed by children with UCLP and then children with CP. Children with CL+/-A show the least problems. In the intervening period, often a combination of treatments was performed. Pharyngoplasty appeared to be very successful in treating hypernasality, with a success rate of 86%. CONCLUSIONS: At early school age, in children with clefts, speech and language problems were significantly improved following a multidisciplinary approach to treatment and resemble their peers without clefts. Hearing problems were more difficult to treat.

Evaluation of the relation between audiometric and psychometric measures of hearing after tympanoplasty.

The objective of this prospective study was to evaluate the relation between audiometric and psychometric measures after tympanoplasty from the perspective of preoperative selection of patients and postoperative assessment of the results of reconstructive middle ear surgery. Hearing (dis)ability was measured by means of pure-tone audiometry and a validated self-assessment questionnaire: the (modified) Amsterdam Inventory of Auditory Disability and Handicap (m)AIAD. Average hearing thresholds and (m)AIAD scores were evaluated for 80 patients, pre- and 12 months postoperatively. The average improvement of the air conduction threshold in the operated ear was 5.4 (+/-14.3) dB; the average improvement in the (m)AIAD score was 2.9 points (+/-12.1). Although not very strong, the audiometric improvement and increase in (m)AIAD score are significantly related. After the calculation of postoperatively measured mean scores on the (m)AIAD for different 10-dB intervals of postoperative hearing loss averaged over both ears, an interesting relation between the (m)AIAD score and hearing losses emerges. The (m)AIAD score is almost independent of hearing loss for postoperative hearing levels between 25 and 40 dB. Residual hearing loss has to become less than 25 dB before a smaller hearing loss corresponds with a higher (better) (m)AIAD score. For losses larger than 40 dB the (m)AIAD score clearly decreases with increasing hearing loss. Finally, even small residual hearing losses lead, on average, to (m)AIAD scores that are substantially lower than the score for normally hearing subjects. In general, the patient benefit seems related to the magnitude of improvement in the air-conduction thresholds, rather than to the achievement of a certain threshold level. In addition, even small residual hearing losses (less than 25 dB HL) still lead, on average, to (m)AIAD scores that are substantially lower than the scores for normally hearing subjects.
