Management of inner nasal valve insufficiency.

OBJECTIVE: To determine the efficacy of the upper lateral caudal edge management in treating patients with inner nasal valve insufficiency and collapse. DESIGN: This was a prospective study in a group of patients suffering from nasal obstruction owing to nasal valve insufficiency. Forty-three patients, who had undergone septoplasty and inferior turbinectomy, were included. All patients presented with nasal obstruction resulting in persistent functional problems. An anatomically narrow nasal valve, valve collapse, or both were found during the clinical examination. SETTING: A tertiary referral centre. METHODS: Revision was undertaken using a new technique to restore the nasal valve, based on upper lateral caudal edge management. MAIN OUTCOME MEASURES: Improvement in nasal airway patency evidenced by patient questioning, by clinical inspection of the nose, and by rhinomanometric results. RESULTS: None of the patients had major complications. In 28 (65.1%) patients, symmetrically improved nasal airway patency and elimination of the subjective sensation of inspiratory collapse was found. In 12 (27.9%) patients, a remarkable asymmetric improvement in nasal obstruction was evident. Two (4.6%) patients reported a moderate breathing improvement, and in only one (2.3%) patient, revision was needed. The mean follow-up time was 18 months. CONCLUSIONS: Our proposed method is an effective therapeutic approach in the management of inner nasal valve insufficiency. It reconstitutes the normal tension of the inner nasal valve and reestablishes the stiffness and resistance of the lateral nasal wall. It can be performed under local anesthesia in cooperative patients, with minimal morbidity and a high rate of success.

The effect of impulse noise on distortion product otoacoustic emissions.

The aim of this study was the evaluation of distortion product otoacoustic emissions (DPOAEs) before and after noise exposure from shooting, and the comparison of DPOAEs with pure-tone audiometry. Thirteen young male police officers were exposed to impulse noise from shooting, without using earplugs. Standard pure-tone audiometry, tympanometry, and DPOAEs were performed before exposure and at one hour post- and 24 hour post-exposure. In the one hour post-exposure testing mean pure-tone thresholds were elevated in the 1-8 kHz frequency zone and DPOAE levels were reduced at several frequencies. DPOAEs were more affected at 3 kHz or lower, whereas pure-tone thresholds were more affected at higher frequencies. After the final examination, non-significant partial shifts at high frequencies on both tests remained. Pure-tone audiometry was overall more sensitive, but DPOAEs provided additional information about the cochlear status of certain ears. These data suggest that besides behavioral testing, DPOAEs may play a role as a fast, objective, and easy to perform test for monitoring subjects exposed to impulse noise.
