A questionnaire using vocal symptoms in quality control of phonosurgery: vocal surgical questionnaire.

BACKGROUND: Quality control after phonosurgery is important and may be time consuming. Often questionnaires focusing on quality of life are applied. We aimed at investigating the use of organ specific symptoms, such as hoarseness and voice failure with the use of self-reported visual analogue scales (VAS) and Likert-scales. METHODS: A vocal surgical questionnaire using VAS and Likert-scales for hoarseness, voice failure and factors that could influence voice quality was given twice consecutively to a group of healthy volunteers (n = 57, 45 female) and a group of voice patients (n = 34, 21 females) for a test/re-test study. Secondly, a group of patients undergoing surgery (n = 90, 61females) answered the questionnaire preoperatively and postoperatively. The difference between test/retest, healthy volunteers and patients, and between pre- and postoperative results were compared. RESULTS: There was no significant difference in the test/retest results in healthy volunteers nor in the patient group. There was statistically significant difference between the healthy volunteers and patients, and between the preoperative and postoperative results after phonosurgery. CONCLUSION: This short and organ specific questionnaire clearly demonstrates the effect of phonosurgery, making it an easy and relevant tool in quality control and potentially reducing the need of postoperative controls in the outpatient clinic.

Paranasal sinus opacification in headache sufferers: A population-based imaging study (the HUNT study-MRI).

Background The association between headache and paranasal sinus disease is still unclear. Because of symptom overlap, the two conditions are not easily studied on the basis of symptoms alone. The aim of the present study was to investigate whether paranasal sinus opacification on magnetic resonance imaging (MRI) was associated with migraine, tension-type headache (TTH) or unclassified headache. Methods This was a cross-sectional study of 844 randomly selected participants (442 women, age range 50-65 years, mean age 57.7 years). Based on 14 headache questions, participants were allocated to four mutually exclusive groups: migraine, TTH, unclassified headache or headache free. On MRI, opacifications as mucosal thickening, polyps/retention cysts and fluid in the five paired sinuses were measured and recorded if ≥1 mm. For each participant, opacification thickness was summed for each sinus and, in addition, a total sum of all sinuses was calculated. Opacification in each sinus was compared between headache-free participants and the headache groups using non-parametric tests, and the total sum was compared by logistical regression. Results No significant association was found between paranasal sinus opacification and headache in general, nor when headache was differentiated into migraine, TTH and unclassified headache. This was also true in separate analyses of mucosal thickening and fluid and of opacification from each paranasal sinus. Conclusion Migraine, TTH and unclassified headache were found not to be associated with an increased degree of paranasal sinus opacification at MRI.

Paranasal sinus opacification at MRI in lower airway disease (the HUNT study-MRI).

The study builds on the concept of united airways, which describes the link between the upper and lower airways. Explorations of this concept have mainly related to asthma and less to chronic obstructive pulmonary disease (COPD). The aim of this study was to investigate paranasal sinus opacification at magnetic resonance imaging (MRI) in COPD, self-reported asthma and respiratory symptoms. In this cross-sectional study, 880 randomly selected participants in the Nord-Trøndelag health survey (HUNT) (mean age 57.7 years, range 50-66 years, 463 women) were investigated using MRI of the paranasal sinuses. Participants were allocated to four mutually exclusive groups: (1) COPD (n = 20), (2) asthma (n = 89), (3) respiratory symptoms (n = 199), and (4) reference group (n = 572). Paranasal sinus opacifications were categorised as mucosal thickening, polyps and retention cysts, and fluid. In each participant, measurements ≥1 mm from all sinuses were summed to give a total for each category of opacities. The sums for these three categories were further added together, and referred to as the total sum. Using the 75th percentile cut-off values, the likelihood of having paranasal sinus opacifications was more than six times higher in participants with COPD and twice as high in participants with asthma than among the reference group. Respiratory symptoms were only associated with mucosal thickening. The present study shows that paranasal sinus opacification is associated not only with asthma, but also with COPD and respiratory symptoms. This is in accordance with the united airways hypothesis, and should be kept in mind when handling patients with these conditions.

Incidental findings in MRI of the paranasal sinuses in adults: a population-based study (HUNT MRI).

BACKGROUND: Diagnostic imaging of the head is used with increasing frequency, and often includes the paranasal sinuses, where incidental opacifications are found. To determine the clinical relevance of such findings can be challenging, and for the patient such incidental findings can give rise to concern if they are over-reported. Studies of incidental findings in the paranasal sinuses have been conducted mostly in patients referred for diagnostic imaging, hence the prevalence in the general population is not known. The purpose of this study was to determine the prevalence and size of incidental opacification in the paranasal sinuses in a non-selected adult population using magnetic resonance imaging (MRI) without medical indication, and to relate the results to sex and season. METHODS: Randomly and independent of medical history, 982 participants (518 women) with a mean age of 58.5 years (range, 50-66) underwent MRI of the head as part of a large public health survey in Norway. The MRIs included 3D T1 weighted volume data and 2D axial T2 weighted image (WI). Opacifications, indicating mucosal thickenings, polyps, retention cysts, or fluid, were recorded if measuring more than 1 mm. RESULTS: Opacifications were found in 66% of the participants. Mucosal thickenings were found in 49%, commonly in the maxillary sinuses (29%) where 25% had opacifications that were less than 4 mm in size. Other opacifications occurred in the anterior ethmoid (23%), posterior ethmoid (21%), frontal sinus (9%), and sphenoid (8%). Polyps and retention cysts were also found mainly in the maxillary sinuses in 32%. Fluid was observed in 6% of the MRIs. Mucosal thickening was observed more frequently in men than in women (P <0.05). No seasonal variation was found. CONCLUSIONS: In this large non-selected sample, incidental opacification in the paranasal sinuses was seen in two out of three participants, and mucosal thickening was seen in one out of two. Fluid was rare. Knowledge of incidental opacification is important because it can affect clinical practice.
