"U-Sniff" - the international odor identification test for children: an extension of its normative database and study of global reliability.

BACKGROUND: To extend the previous study by Schriever and colleagues from 2018 providing normative data and re-investigating the reliability for U-Sniff test in children in additional countries. METHODOLOGY: A total of 388 children (196 boys, 192 girls) from eight countries (China, Germany, Iran, Netherlands, Norway, Oman, Paraguay, and Russia) participated in this study. The children were recruited from public local schools in those particular countries. The odor identification ability was evaluated using the U-Sniff test, a 12-item odor identification test developed for children. In addition, reliability was examined using test-retest design in the children for each country. RESULTS: The mean U-Sniff test score across all children was 10.3 +- 1.7 points. Normative data were established. A high test-retest reliability of the U-Sniff test was demonstrated across the eight participating countries. CONCLUSIONS: The U-Sniff test for children exhibits a high test-retest reliability on a global scale.

Nasoseptal flap for palatal reconstruction after hemi-maxillectomy: case report.

OBJECTIVE: Palatal reconstruction following maxillectomy is a surgical challenge, and a nasoseptal flap is a feasible approach. This paper reports the first known successful clinical case of a nasoseptal pedicle flap applied for the reconstruction of maxillary bone following hemi-maxillectomy. CASE REPORT: This report describes hemi-maxillectomy in a 60-year-old Italian male diagnosed with stage IV squamous cell carcinoma of the left maxilla. Endoscopic transnasal extended medial maxillectomy was performed, followed by a transoral modified midfacial degloving technique for removal of the maxillary bone. The contralateral nasoseptal pedicle flap was used to reconstruct the defect. The case was followed up prospectively for the assessment of flap reception and healing. CONCLUSION: The locally accessible nasoseptal flap is a viable alternative for palatal reconstruction; therefore, a second surgical procedure with its associated donor site morbidity can be avoided. Large-scale studies may help in establishing the cosmetic and functional outcomes.
