Diagnosing nasal obstruction and its common causes using the nasal acoustic device: A pilot study

Nasal septal abscess is an uncommon condition. Most commonly it is secondary to nasal trauma, which leads to haematoma, and subsequent abscess formation. There are other less common causes like sinusitis, dental infections and furunculosis. Non-traumatic nasal septal abscess has also been reported in immunocompromised individuals. We report a case of non-traumatic, spontaneous nasal septal abscess, in a healthy immunocompetent patient with no evidence of sinusitis or other localized infections. Using Medline and Google.co.uk search applications, there has been one previous report of such a condition. We stress the importance of excluding nasal septal abscess in patients presenting with nasal obstruction especially with signs of toxaemia.

AbstractThis article aims to demonstrate the concept and potential of a novel diagnostic device – the nasal acoustic device (NAD), which captures the nasal breathing sounds over the ala on both sides of the nose. Using the newly defined inspiratory nasal acoustic score (INA score), the unique characteristics of the nasal breathing sounds can be quantified and used for diagnostic purposes.In this pilot study, the NAD was compared with the well-established nasal inspiratory peak flow meter (NIPF) to try to distinguish between subjects with and without chronic rhinosinusitis (CRS). Measurements were made before and after nasal decongestants, which were applied to eliminate the nasal cycle. Patients were divided into two groups based on the presence or absence of CRS, irrespective of other pathological conditions being present.Based on the post-decongestant measurements, the sensitivity/specificity in distinguishing subjects who have CRS (n=11) from subjects who do not (n=29; of whom 13 were controls) were 70%/66% for the NIPF and 82%/79% for the NAD. The non-CRS groups showed statistically significant changes after decongestant for both methods, but the CRS group did not. The results firstly demonstrated that the CRS subjects in this cohort tended to be less responsive to decongestant and therefore the post-decongestant NIPF measurements provided a certain degree of diagnostic value in identifying CRS subjects, but it would appear the NAD better captured the unique sounds associated with CRS, providing a superior diagnostic capability. This study also demonstrates that the NAD can measure the improvement in the nasal airway following treatment effect.

Life Threatening

An infant with severe, life-threatening respiratory distress due to allergic rhinitis is described. Since this has not been previously reported, a plea is made for the consideration of allergy as a cause of acute nasal obstruction in the newborn after other more common causes, and certain unusual ones reviewed above, have been ruled out.

Inferior Turbinate Hypertrophy

A pilot study to assess the safety and efficacy of ’degloving’ of the inferior turbinate is described. This prospective study reports on the effectiveness of the technique in 37 patients with nasal obstruction due to inferior turbinate hypertrophy. Both objective and subjective measurements of nasal patency were made pre-operatively, and repeated at six weeks, six months and two years post-operatively using nasal inspiratory peak flow rates, saccharin clearance time and an end referenced visual analogue scale to record nasal symptoms.There was a significant improvement in the peak inspiratory flow at six weeks (96.4 to 151.2 l/min) and at six months (148.4 l/min), which was sustained at two years (117.1 l/min, p<0.001). There was an overall improvement in patient satisfaction with nasal symptoms (23.4 to 76.7, 76.8 and 66.8 at six weeks, six months and two years, p<0.001) and a decrease in the sensation of nasal obstruction (71.9 to 21.5, 32.9 and 29.8, p<0.001), which was also sustained. Rhinorrhoea was reduced, and sense of smell increased across the group, but the improvements did not reach statistical significance. The results for postnasal drip and saccharin clearance did not show a significant change over the period of the study. There were no haemorrhagic complications in the group studied.This pilot study demonstrates a new surgical technique for reduction of the inferior turbinates, that yields significant improvement in nasal obstruction, an acceptably low complication rate and is well tolerated by patients. A randomized controlled trial is being planned.

Turbinate Reduction

Background: Nasal obstruction is a common complaint in ENT clinics and significantly affect the patient`s quality of life. Inferior turbinate hypertrophy is one of the common causes of nasal obstruction, surgical reduction of inferior turbinate is indicated in refractory cases not responding to conservative measures and the optimal surgical technique is controversial. The aim of the study was to evaluate the clinical outcomes of powered endoscopic inferior turbinoplasty in the management of inferior turbinate hypertrophy. Methods: An interventional study (single group clinical trial) was conducted and powered endoscopic inferior turbinoplasty was performed on 30 patients complaining of chronic nasal obstruction due to inferior turbinate hypertrophy and other causes of nasal obstruction were excluded. Results: Assessed preoperatively and 1st week, 1st month and 3rd month postoperatively depending on subjective visual analogue scale scores for nasal obstruction, endoscopic grading system and complications. There was significant improvement in nasal obstruction and significant reduction in inferior turbinate size and mild complications that completely absent at the third month following the surgery. Conclusions: Microdebrider-assisted inferior turbinoplasty as a safe, effective and reliable alternative method for inferior turbinate reduction.
