Objectives: In this study, we designed a new technique for open septal reduction using a polydioxanone (PDS) plate and compared it with closed reduction. Design, Setting, Participants: This study included nineteen consecutive patients with nasoseptal fracture: ten receiving open reduction with a PDS plate (PDS group) and nine undergoing closed reduction (CR group). Open septal reduction was performed after closed reduction for nasal bone fracture. A mucoperichondrial flap was unilaterally elevated, and the deviated septal cartilage was reduced. The PDS plate was inserted horizontally above the vomerine suture. Surgical outcome was analyzed with three-dimensional volumetry and with a quality-of-life scale for nasal obstruction (NOSE scale). Results: Complications included one case of septal perforation in the CR group and one case of PDS exposure and septal hematoma in the PDS group. In the 3D volumetric analysis of the PDS group, the median value of the nasal cavity change significantly differed between 1.14 mL (interquartile range; 0.46 to 2.4) at the preoperative CT scan and 0.33 mL (interquartile range; -0.22 to 1.29) at the postoperative CT scan (**p = 0.0039). The NOSE scale revealed significant improvement in nasal obstruction postsurgically (median value, 42.5 to 7.5; *p = 0.0139) in the PDS group. Conclusion: PDS plates potentially present a new concept of open septal reduction in terms of septal reinforcement compared with the subtractive approach of open septal reduction.

Objective Reporting patient symptoms due to nasal septal perforation (NSP) has been hindered by the lack of a validated disease-specific symptom score. The purpose of this study was to develop and validate an instrument for assessing patient-reported symptoms related to NSP. Study Design Validation study. Setting A tertiary care center. Methods The Nasal Obstruction Symptom Evaluation (NOSE) scale was used as an initial construct to which 7 nonobstruction questions were added to measure septal perforation symptoms. The proposed NOSE-Perf instrument was distributed to consecutive patients evaluated for NSP, those with nasal obstruction without NSP, and a control group without rhinologic complaints. Questionnaires were redistributed to the subgroup with NSP prior to treatment of the perforation. Results The study instrument was completed by 31 patients with NSP, 17 with only nasal obstruction, and 22 without rhinologic complaint. Internal consistency was high throughout the entire instrument (Cronbach α = 0.935; 95% CI, 0.905-0.954). Test-retest reliability was demonstrated by very strong correlation between questionnaires completed by the same patient at least 1 week apart ( r = 0.898, P < .001). Discriminant validity was confirmed via a receiver operating characteristic ( P < .001, area under the curve = 0.700). The NOSE-Perf scale was able to distinguish among all 3 study groups ( P < .001) and between NSP and nasal obstruction ( P = .024). When used alone, the NOSE scale could not discriminate between NSP and nasal obstruction ( P = .545). Conclusions The NOSE-Perf scale is a validated and reliable clinical assessment tool that can be applied to adult patients with NSP.

Objectives: To prevent aesthetic and functional deformities, precisely closed reduction is crucial in the management of nasal fractures. Plain film radiography (PF), ultrasonography (USG), and computed tomography can help confirm the diagnosis and classification of fractures and assist in performing closed reduction. However, no study in the literature reports on precisely closed reduction assisted with PF measurements under the picture archiving and communication system (PACS). Methods: We retrospectively evaluated 153 patients with nasal bone fracture between January 2013 and December 2017. Surgeons conducted precisely closed reduction assisted with PF measurement of the distance between the fracture site and nasal tip under PACS on 34 patients (group A). Another group on 119 patients were reduced under surgeon’s experience (group B). Results: No significant differences in age, gender, Arbeitsgemeinschaft fur Osteosynthesefragen (AO) classification, and reduction outcome were observed between group A and group B ( P > .05). The operative time of the group A was significantly lower (12.50 ± 4.64 minutes) compared to group B (23.78 ± 11.20 minutes; P < .001). After adjusted age, gender, and AO classification, patients in group A scored 10.46 minutes less on the operative time than those in group B ( P < .001). In addition, the severity of nasal bone fracture (AO classification, β = 3.37, P = .002) was positive associated with the operative time. Conclusions: In this study, closed reduction in nasal bone fracture assisted with PF measurements under PACS was performed precisely, thereby effectively decreasing operative time and the occurrence of complications. This procedure requires neither the use of new instruments or C-arm nor USG or navigation experience. Moreover, reduction can be easily performed using this method, and it requires short operative time, helps achieve great reduction, less radiation exposures, and is cost-effective.

Purpose: To investigate the influence of breathing mode and nasal patency in the dimensions of the hard palate by comparing mouth breathing (MB) and nasal breathing (NB) adults. Methods: Seventy-seven individuals, distributed into the MB group (n=38) and the NB group (n=39), of both genders and aged between 18 and 30 years old, took part in the study. The respiratory mode diagnosis was based on anamnesis, physical characteristics, and otorhinolaryngological examination. The volunteers were evaluated in terms of nasal patency, with a peak nasal inspiratory flow (PNIF) meter, and obstruction symptoms, by a Nasal Obstruction Symptom Evaluation (NOSE) scale, and had their transversal and vertical hard palate dimensions measured with a digital caliper in plaster models. Results: Comparing both groups, the MB group presented significantly higher values in the NOSE scale, lower values in the PNIF, lower values in the transversal distance of the palate in the intercanine region, and significantly higher values in the vertical distance in the regions of the first and second premolars and molars. There was a negative correlation between PNIF and NOSE, and a positive correlation between PNIF and transversal distance of the palate in the region of the first premolars. Conclusion: MB adults presented reduced nasal patency and a higher degree of nasal obstruction symptoms. The hard palate was morphologically narrower and deeper in adults with the MB mode compared to the NB mode. Moreover, it was concluded that the smaller the nasal patency, the greater the obstruction symptoms and the narrower the hard palate.

Background Because nasal function and shape are so closely intertwined, quantitative assessments can better define their relationship and how they are affected by septorhinoplasty. Objective The aim of this prospective study was to perform an analysis of the nasal airflow resistances and a three-dimensional (3D) evaluation of the soft-tissue changes after closed septorhinoplasty. Methods Before surgery (TO) and 6 months after closed septorhinoplasty (Tl), 30 patients underwent symptoms evaluation by means of the Italian version of the Nasal Obstruction Symptom Evaluation scale, endoscopic fiberoptic nasal examination, and visual analog scale for subjective assessment of nasal obstruction. Nasal airflow resistances were investigated with active anterior active rhinomanometry. A 3D laser scanner was used to evaluate facial soft-tissues, with specific nasal points and angles. Results Subjective nasal obstruction decreased. Anterior active rhinomanometry demonstrated a reduction in total inspiratory and expiratory resistances between T0 and T1 but without statistical significance. The significance was still absent after decongestion, excluding turbinate hypertrophy as a cause of failed objective amelioration of nasal resistance. Facial laser scanning showed statistically significant reduction of the superior nasal width and superior alar angle, and a weak negative correlation between the superior alar angle and nasal resistances. Conclusion The absence of objective reduction of nasal airflow resistances could be the result of concurrent surgery on nasal septum and nasal valve. In particular, the ameliorating effect on nasal airflow resistances is counterbalanced by the worsening effect of the narrowing of nasal valve.
