- We present the fabrication and clinical use of a custom-made nasal septal silicone button that can be inserted transnasally into a perforation of the nasal septum by the physician as an office procedure, or by the patients themselves in their home. Questionnaire and retrospective chart review were used to evaluate the efficacy of this prosthesis as treatment of disturbing symptoms from nasal septal perforation. The study included 41 patients (27 women) with a nasal septal perforation. The follow-up time ranged from 1 to 9 years. Symptoms investigated were nasal obstruction, crusting, feeling of dryness, pain, epistaxis, and whistling from the nose. The degree of experienced symptoms was estimated on a VAS-scale. The questionnaire was answered by 37 of the 41 patients. Fourteen patients were still using their button at the follow-up. Treatment with the prosthesis greatly diminished all the investigated symptoms. Also, use of the silicone button resulted in an improved quality of life. No case of infection was noted in connection with use of the silicone prosthesis.

- This study is the first to validate the Rhinolux against acoustic rhinometry in detecting nasal mucosal swelling when changing body position from sitting to supine. The Rhinolux (Rhios GmbH, Germany) is a new device using a light-absorption technique called nasal spectroscopy and to measure changes in nasal blood volume as a sign of nasal mucosal swelling in real time. The relationship between the changes in nasal blood volume measured with the Rhinolux and changes in nasal mucosal swelling has however, not previously been validated objectively. To evaluate this relationship we compared the Rhinolux to acoustic rhinometry following the change in body position from sitting to supine. The study population consisted of 20 healthy subjects (7 women, 13 men, mean age 34.7 +/- 9.3 years). The Rhinolux was applied sitting in the upright position followed by 5 min in the supine position. Acoustic rhinometry was measured sitting in the upright position and after 5 min in the supine position. In seven subjects the measurements were repeated on three different days to assess the repeatability. The mean change from baseline in minimal cross sectional area DeltaMCA measured with acoustic rhinometry was -0.12(+/-0.19) cm2 (right + left side), P = 0.013 but DeltaE (change in light extinction from baseline) measured with the Rhinolux was unchanged 0.02(+/-0.18) optical densities (OD), P = 0.56. There was no correlation between DeltaE and DeltaMCA r = 0.028, P = 0.9. The mean DeltaE result from repeated measurements on different days was 0.05(+/-0.08) OD, P = 0.09 and the DeltaMCA was -0.1(+/-0.11) cm2, P = 0.02. This study showed that the changes in nasal blood volume measured with the Rhinolux did not reflect changes in nasal mucosal swelling measured with acoustic rhinometry when changing body position from sitting to supine. The results indicate that the utility of the Rhinolux in assessing nasal mucosal reactions has to be evaluated further.

- We assessed the regulation of nasal patency supine in subjects with obstructive sleep apnoea syndrome (OSAS) compared to healthy controls. Healthy subjects increase nasal obstruction when changing body position from sitting to supine, possibly due to increased hydrostatic pressure in the head supine. Limited data indicate that this response is altered in patients with OSAS, suggesting that supine nasal patency is actively regulated. This study examined the nasal response to recumbent body position using acoustic rhinometry in OSAS patients and healthy controls. Twenty subjects (16 men and 4 women, mean age 55 +/- 16 years), with diagnosed OSAS [mean apnoea hypopnoea index (AHI) 46 +/- 22 events/h] without nasal obstruction and continuous positive airway pressure (CPAP)-naive, underwent measurement of intra-nasal cross sectional area by acoustic rhinometry at sitting and after 5 min supine. Twenty healthy controls (13 men, 7 women, mean age 35 +/- 9 years) were also included in the study. In the patients with OSAS, the mean minimal cross sectional area (MCA, left + right nasal cavity) was unchanged between sitting (1.18 +/- 0.41 cm(2)) and supine (1.21 +/- 0.35 cm(2), P = 0.5). In the healthy controls, the mean MCA decreased from 1.06 +/- 0.18 to 0.94 +/- 0.21 cm(2) supine, P = 0.01. This study showed that the normal decrease in nasal patency following a change in body position from sitting to supine is absent in patients with OSAS. The results indicate that there is an active regulation of supine nasal patency.

Correlation of Vestibular Evoked Myogenic Potentials and Electronystagmographic findings in patients with Sudden Hearing Loss
- 2007

- Objectives: Vestibular Evoked Myogenic Potentials (VEMPs) are electric potentials, used as a parameter for the assessment of the otolith function. They can be recorded after sound stimulation with surface electrodes over each sternocleidomastoid muscle. The purpose of the study is to investigate VEMPs and correlate them with the electronystagmic findings in cases of Sudden HearingLoss (SHL).Methods: Pure tone audiometry, acoustic immittance testing, caloric testing, Auditory Brainstem Responses and VEMP testing was performed on 34 patients with unilateral idiopathic SHL. Same testing was performed on a control group of healthy volunteers. VEMP responses were measured and compared to caloric responses.Results: VEMPs were present in all normal subjects of the control group and ipsilaterally normal on the unaffected side in all patients with SHL. Twenty five out of 34 patients (73,53%) showed normal VEMP responses. In 13 patients both electronystagmographic findings and VEMPs were normal, but in 12 patients VEMPs were normal but there were abnormal caloric responses (canal paresis in 7 patients, spontaneous nystagmus in 5 patients). Nine patients displayed abnormal VEMPs (26,47%) on the affected side (in eight cases absent, in one case delayed) and eight of them demonstrated decreased caloric responses, while one patient had normal caloric responses.Conclusions: In a considerable number of cases VEMPs were abnormal. However, most of the patients displayed normal VEMPs. Also, in the majority of patients, VEMPs correlated to the caloric responses, although in a certain number of cases either the superior or the inferior vestibular nerve was involved.

- The purpose of this study was to elucidate whether misdirected swallowing is an extra-laryngeal cause of hoarseness and investigate whether the prevalence of misdirected swallowing and hoarseness in patients with hiatal hernias differ from those with and without pathological gastroesophageal reflux (GER). One hundred and ninety eight patients with hiatal hernias diagnosed via esophageal manometry and pH-reflux test and 262 subjects in the general population who did not have a hiatal hernia at endoscopy, filled in a questionnaire about symptoms on hoarseness, misdirected swallowing, and heartburn. Hoarseness (35%), misdirected swallowing to the larynx (MSL; 35%), misdirected swallowing to the nose (MSN; 22%) and heartburn (85%) were significantly more common in patients with hiatal hernia than in controls (13, 5, 1, and 6%, respectively, P<0.001). MSL and MSN in the patient group were significantly interrelated (P<0.0001). Hoarseness and MSL were not significantly associated (P<0.076). Hoarseness and MSL were as common in the hernia group with normal GER, as in the group with pathological GER. There is a predisposition for hoarseness and MSL in patients with hiatal hernias, but the cause-and-effect relationship is unclear. Hoarseness does not seem to be caused by pathological GER.

An office procedure to detect vestibular loss in children with hearing impairment
- 2005

- As coexisting vestibular and cochlear lesions are of etiological importance, evaluation of children with congenital or early acquired hearing impairment (HI) should include vestibular assessment. A rotation test requires specific equipment and allows only detection of bilateral vestibular impairment. An impulse or head thrust test allows assessment of one ear at a time, detects more pronounced caloric side differences and can be performed without any equipment. We report a consecutive series of children with profound sensorineural HI investigated at a tertiary hospital unit. Age at taking first steps without help, the results of temporal bone images (CT/MRT) and vestibular tests were collected retrospectively from patient files. The children were 12 to 90 months old at the time they attended both a rotation and an impulse test. All 14 children cooperated in the impulse test, and 12 completed the vestibular rotation test successfully. Three out of 14 children tested so far have been confirmed to have a bilaterally pathological vestibulo-ocular reflex confirmed both in the rotation test and the impulse test. Our results show that both the rotation test and the vestibular impulse test can be successfully performed on small children at a regular outpatient appointment.

Functional effects of repeated pressure loads upon the tympanic membrane : mechanical stiffness measurements after simulated habitual sniffing.

Ingår i: European Archives of Oto-Rhino-Laryngology. - : Springer Science and Business Media LLC. - 0937-4477 .- 1434-4726. ; 266:8, s. 1219-24

- In experimental studies it was found that otitis media causes stiffness loss in the tympanic membrane, possible precursors to retraction pockets and cholesteatoma. Besides otitis media habitual sniffing behaviour is associated with the development of retractions. The present study aims to test the hypothesis that repeated sniffing manoeuvre may cause not only structural, epithelial tympanic membrane changes presumed to be possible precursors to retractions, but also tympanic membrane stiffness loss, another possible mediator for the development of retractions. An experimental model with a pressure chamber was used to mimic the pressure conditions for the tympanic membrane in habitual sniffers' ears. The stiffness properties of twelve Mongolian gerbil tympanic membranes were measured with moiré interferometry after varying time up to 12 days with repeated pressure loading. Three days later, lower overall displacement were obtained in two ears; after 7-12 days the displacement readings were normal. This study with maximum of 12 days of pressure loading did not verify the hypothesis that habitual "sniffing" impairs the stiffness of the tympanic membrane.
