Role of nasal valve in the surgically corrected nasal respiratory obstruction: evaluation through rhinomanometry.

The aim of this study was to evaluate the improvement of nasal flow and the fall of nasal resistance in 50 patients that underwent rhinoseptoplasty in our department and discuss the relative importance of valvular and septal deformities in nasal airway obstruction. Fifty consecutive patients underwent rhinoseptoplasty to improve nasal obstruction caused by severe septal deviation, external or internal valvular incompetence, or any combination of the three. We excluded patients with minor septal curvatures, septal perforations, or turbinate hypertrophy. Preoperative and postoperative rhinomanometry was performed on all 50 patients. In all 50 patients, septal and/or valvular surgery lowered nasal resistance in 90% of cases. Septoplasty alone with medial and basal osteotomies did not improve nasal flow (p < 0.4), whereas the correction of valvular obstruction alone increased nasal airflow in a statistically significant way (p < 0.0001). Moreover, patients with both valvular incompetence and septal deviation represented the group in which the greatest preoperative obstruction and the greatest postoperative improvement occurred. Nasal valvular function should be assessed with rhinomanometry in all preoperative rhinoplasty patients with airway obstruction. In many cases, valvular effects may surpass septal deviation as the primary cause of nasal airflow obstruction.

Overdentures on natural teeth: a new approach.

AIM: The study presents a new type of copings for overdentures on natural teeth. METHODS: A new type of custom-made copings was prepared on 10 extracted teeth and their marginal fit was observed microscopically by means of a mechanical device, and software was employed to measure the gap. RESULTS: The marginal fit evaluation gave satisfactory values with mean values of the gap measurements below the clinically accepted limits (mean gap: 25.3 microm; minimum 7.3 microm, maximum 56.5 microm). CONCLUSIONS: The advantages of these new copings are: the rapidity of their preparation; the protection of the root canal treatment, because the coping with this chair-side method is prepared and cemented in one session; the low costs.
