BackgroundOtitis media (OM) is a major health problem that usually results from adenoid hypertrophy. Diagnosis is based on symptoms like mouth breathing and imaging studies like lateral neck radiography (LNR). Adenoid-nasopharyngeal ratio (A/N ratio) is one of the most important and most widely used criteria in LNR study that could estimate the real size of adenoid gland measurements. However, there are huge controversies regarding LNR rules in the management of patients with OM.ObjectiveThis study aimed to determine Adenoid Nasopharyngeal Ratio (A/N ratio) in children with otitis media with effusion (OME) and its relation with different factors.MethodsThis was a cross-sectional study on OME suspected children who needed adenoidectomy. The study was conducted from the fall to winter of 2016 on patients referred to ENT clinics of Mashhad University of Medical Sciences. Before surgery, all children underwent standard LNRs and indirect laryngoscopy to assess adenoidal size, and nasopharyngeal length, and A/N ratio. After adenoidectomy, pathologic analysis was performed for assessment of pathologic size. SPSS 21 was used for data analyzing using Pearson’s correlation, independent t test and Mann-Whitney U test (p<0.05 was considered significant).ResultsA total of 27 children were enrolled. Most of the patients were male (70.4%, mean age=7.81±2.52 year). All patients in the study were symptomatic and the most frequent symptom was mouth breathing (100%). The mean A/N ratio, pathologic adenoid size, and laryngoscopic adenoid size were 0.825±0.099, 18.22±5.97, and 5.33±19.15 mm. There was a significant correlation between the A/N ratio laryngoscopic adenoid size (r=+0.46, p=0.01) and pathologic adenoid size (r=+0.44, p=0.02).ConclusionsThe results of this study showed that A/N ratio can be used to estimate the actual size of the adenoid gland and the necessity of adenoidectomy. Considering the reasonable costs and availability of this diagnostic method, researchers recommend using this procedure in assessment of patients with OME.

Background: Laryngeal cancer is one of the most common head and neck cancers for which total laryngectomy is the preferred treatment in advanced stages. Major disabilities of this surgical procedure include loss of voice and nasal function, swallowing difficulties, and psychological consequences. Objectives: This study aimed to investigate the effect of the Polite Yawning technique on olfactory quality in patients undergoing total laryngectomy. Methods: In this cross-sectional study, after total laryngectomy, the patients with olfactory dysfunction were enrolled and the quality of olfaction was evaluated by the Quick Odor Detection test before and after receiving the Nasal Airflow Inducing Maneuver technique training. Statistical analysis was performed using SPSS 21 software by the Wilcoxon or McNemar’s test. The significance level was considered for P ≤ 0.05. Results: A total of 40 patients were evaluated. The mean age was 55.98 ± 6.27 years. Eighty-five percent of the patients were male (n = 34). The difficulty score in learning maneuvering was 2.5 ± 1.3, and 90% had no problem with learning it. Before maneuver, none of the patients had normal olfaction and had hyposmia mostly (n = 32, 80%). Immediately after the maneuver, there was a sensation of smell in all patients and the rate of hyposmia in patients was reduced to 65% (P = 0.008). Normal olfactory status was reported in half of the patients one month after the maneuver (21 patients, 52.5%, P = 0.0001), and there was a sense of smell in all patients (P = 0.0001). Conclusions: The results proved that olfactory quality can be rehabilitated after laryngectomy by the nasal airflow-inducing maneuver (the “Polite Yawning” technique). It is a patient-friendly method; however, a single training session is probably insufficient and most patients may need more training sessions.
