This study is the first to characterize outcomes following cervical decompression in patients with PD and CSM. PD patients experienced symptomatic improvement but less overall improvement in myelopathy compared to controls. However, PD patients demonstrated improvement in upper extremity motor, upper extremity sensory, and sphincter symptoms no worse than control patients.

Objective: So far, no original studies explored non-randomized, standardized protocols for COVID-19 associated olfactory dysfunction. The main objective was to determine the efficacy of a new protocol for post-COVID olfactopathy while assessing the benefit of adding adjuvant therapies to olfactory training. Methods: Patients suffering from long-lasting post-COVID-19 olfactory dysfunction were evaluated. A non-randomized protocol based on individual nasal endoscopy findings and patient’s preferences was applied. Patients were assigned for olfactory training alone or olfactory training + adjuvant therapy. Participants performed olfactory objective and subjective evaluations at first consultation and 3 months after treatment, and results were compared. Results: A total of 47 patients were enrolled. All groups showed significant improvement in olfactory thresholds at 3-month follow-up suggesting protocol effectiveness (olfactory training group alone showed a mean threshold difference of 2.9, P < .001; Olfactory training + Topical Corticosteroid showed a mean threshold difference of 4, P = .006; Olfactory training + Topical Corticosteroid + Vitamin B complex showed a mean threshold difference of 4.4, P = .006; Olfactory training + Intranasal Vitamin A and E showed a mean threshold difference of 4.4, P < .001). Olfactory training alone showed lower mean olfactory threshold improvement, when compared to patients undergoing olfactory training + adjuvant therapy (olfactory training alone mean improvement 2.9 ± 2.3 vs olfactory training + adjuvants mean improvement 4.3 ± 2.458, P = .03). Conclusions: This is one of the first studies to demonstrate results in the treatment of post-COVID-19 persistent olfactory impairment. A customized approach based on endoscopy findings and patient’s preferences may be a valid option for the management of persistent post-COVID-19 olfactory disorder. Adjuvant therapy could be considered in addition to olfactory training, but further studies are needed in order to confirm their effectiveness in this setting. Level of evidence: 2c (outcomes research).

Background: The anterior superior alveolar nerve (ASAN) plays a major role in innervation of the lateral nasal wall. Its damage during nasal surgery can cause dental paraesthesia and numbness around the upper lip. Methodology: Retrospective evaluation of the computed tomographic (CT) scans of 50 consecutive patients analysing 100 sides. We measured the mean distance from the shoulder of the inferior turbinate to the descending portion of the anterior superior alveolar nerve, to the anterior superior alveolar canal and the anterior-posterior distance between the “shoulder” of the inferior turbinate and the pyriform aperture. Results: The mean distance from the shoulder of the inferior turbinate to the descending portion of the anterior superior alveolar nerve was 6.4 ± 2.33 mm, with no difference between sides The mean relative height of the shoulder in relation to the anterior superior alveolar nerve canal was 4.78± 2.31mm with no significant difference between the two sides. The anterior-posterior distance between the “shoulder” of inferior turbinate and the pyriform aperture was 6.96± 2.28mm, with no significant difference between the two sides. Conclusions: We found the anterior superior alveolar nerve to be a constant landmark in the lateral nasal wall. Therefore, the course of the ASAN should be assessed on a CT scan when a surgical approach through the pyriform aperture or anterior medial wall of the maxillary sinus is planned.

IntroductionOlfactory dysfunction (OD) is often a devaluated sensorial affection. The objective evaluation of this dysfunction doesn't evaluate its compromise in patients' daily life. Therefore, the use of a Portuguesevalidated tool is of uttermost importance to objectively scale the pathology presented by these patients. ObjectiveWe aim to validate and cross-culturally adapt the Olfactory Disorders Questionnaire (ODQ) in the Portuguese language. MethodsA prospective study was carried out to evaluate and compare 56 consecutive patients who had olfactory disorders and 54 asymptomatic controls. A cross-cultural adaptation process was taken into account in order to transform the original English tool into a valid Portuguese version. We explored the psychometric properties of the European-Portuguese version of the Portuguese version of ODQ (PT-ODQ) concerning its internal consistency, reproducibility, feasibility, and discriminatory validity. ResultsCronbach alpha for the tool was 0.924 showing strong internal consistency. We also found a statistically significant difference in PT-ODQ between patients with olfactory disorders and patients without olfactory disorders, according to the Mann-Whitney test. ConclusionsThe PT-ODQ seems to be a valid tool for assessing the individual effect of olfactory disorders on patients' quality of life and, therefore, could be applied in olfactory disorders research and daily practice.
