Thermal welding tonsillectomy is a relatively safe and reliable method with significantly less postoperative morbidity than cold dissection tonsillectomy.

Objectives: Pott's puffy tumor (PTT) is a frontal subperiosteal abscess associated with underlying frontal osteomyelitis. The purpose of the present study was to assess the rate of intracranial involvement in pediatric and adolescent patients with PPT and to discuss the diagnostic workup and the therapeutic features of this pathology.Methods: We searched Web of Science, PubMed and MEDLINE from 1998 to 2018. The search focused on papers concerning the diagnostic procedure and therapeutic management of PTT. Statistical techniques were not used.Results: We included 53 articles that described 92 pediatric and adolescent patients with PPT. The overall rate of intracranial complications was found to be 72%. Most authors used computed tomography for the diagnosis of PTT and its complications, either alone or in combination with magnetic resonance imaging. In 50% of cases, an endoscopic endonasal approach is used for the management of the underlying acute or chronic sinusitis.Conclusions: On the basis of the available literature, it seems that the incidence rate of intracranial involvement in patients with PPT is quite high. Early diagnosis using the appropriate imaging raise the possibility of good recovery. Concerning the therapy of PTT, endoscopic sinus surgery could be considered as a valuable technique. The vast majority of patients treated appropriately recover without long-term neurologic complications and sequelae.

The Greek-NOSE questionnaire is a valid instrument with satisfactory internal consistency, reliability, reproducibility, validity, and responsiveness.

The aim of this study was to perform translation, cross-cultural adaptation, and validation of the sinonasal outcome test 22 (SNOT-22) in the Greek language. SNOT-22 was translated into Greek. A prospective study was conducted on adult patients with chronic rhinosinusitis (CRS) according to rhinosinusitis and nasal polyps (EPOS) criteria. Test-retest evaluation of the patients was carried out. Internal consistency was assessed with Cronbach's alpha test, and test-retest reliability with Pearson's test (parametric correlation coefficient), kappa (reproducibility) and Bland-Altman plot (extent of agreement). Validity was assessed by comparing scores between a control group of volunteers without CRS and the CRS group using Mann-Whitney test. Responsiveness was assessed on CRS patients who underwent surgery, by comparing preoperative to 3 months postoperative scores with paired t test. Furthermore the magnitude of surgery effect was evaluated. Test-retest evaluation was accepted in 64 patients. Cronbach's alpha was 0.84 and 0.89 at test and retest, respectively, suggesting good internal consistency. Pearson's correlation coefficient was 0.91 (p < 0.001), revealing good correlation between initial and retest scores. Mean kappa value was 0.65, indicating a high level of reproducibility, while in Bland-Altman plot the differences were located between agreement thresholds. The control group consisted of 120 volunteers. Mann-Whitney test showed a statistically significant lower score for the control group (p < 0.0001). 32 CRS patients underwent surgical treatment. Postoperative scores were significantly lower than preoperative (p < 0.0001) while the magnitude of surgery effect was considered high. Greek SNOT-22 is a valid instrument with good internal consistency, reliability, reproducibility, validity and responsiveness.
