Sinonasal Disease

Objective: Total laryngectomy (TL) results in complete abolition of nasal airflow, with notable pathologic alterations of the intranasal mucosa, mucociliary clearance, and nasal cycle. Despite these observed morphological changes, it remains unclear whether this subpopulation of patients experiences clinically significant sinonasal disease. The goal of this study was to identify rhinosinusitis in TL patients using radiographic imaging. Methods: An Institutional Review Board–approved retrospective review (January 2005-July 2017) identified 50 patients who underwent radiographic imaging before and after TL. The Lund-Mackay Staging System (LM) was applied to 197 surveillance computed tomography scans. Surveyed patients also underwent investigation of current sinonasal symptomatology using the SNOT-22 questionnaire. Simple linear regression was modeled to LM scores; tests of statistical significance were estimated via the method of Kenward and Roger. Results: The mean age was 62.4 years, with a 5:1 male-to-female ratio. The mean SNOT-22 score was 27.4 (range, 5-33). A median of 3 scans was obtained, 49% within 12 months after TL. The mean (± standard deviation) postoperative LM score was 2.7 ± 3.97 points (range, 0-19). For every 1 month after TL, postoperative LM was +0.01 point ( P = .49). Conversely, for every +1 point in preoperative LM, postoperative LM was +1.08 points ( P < .001). Two patients required functional endoscopic sinus surgery after TL for persistent sinonasal disease. Conclusions: Preoperative sinonasal disease burden likely plays an important role in the development of clinically significant rhinosinusitis in TL patients. Correlating radiographic findings to validated outcome measures remains a critical aspect of determining optimal surgical candidates; this arena is still under investigation in this unique patient cohort.

Abstract Intervertebral discs are important structural components of the spine but also are significant sources of morbidity, especially for the “low back” lumbar region. Mechanical damage to, or degeneration of, the lumbar discs can diminish their structural integrity and elicit debilitating low back pain. Advancement of reparative or regenerative means to treat damaged or degenerated discs is hindered by a lack of basic understanding of the disc load-deformation characteristics in vivo. The current study presents an in vivo analysis of the morphometry and deformation of lumbar (L2-S1) intervertebral discs in 10 healthy participants while performing a common lifting act, using novel dynamic radiographic imaging of the lumbar vertebral body motion. Data analyses show uniquely different (p < 0.05) characteristics in morphometry, normal and shear strain patterns of the L5S1 discs, while the rest of lumbar discs exhibit great similarity. In particular shear strains in L2-L5 discs exhibited stronger linear correlations (R2 ≥ 0.80) between strain changes and amount of lumbar flexion-extension motion compared to L5S1 (R2 ≤ 0.5). The study therefore advances the state of knowledge on in vivo mechanical responses of the lumbar intervertebral discs during functional tasks.

Chondrosarcomas of the larynx are rare cancers, representing less than 1% of all laryngeal tumors. The most often involved site is the cricoid cartilage. They have generally good prognosis, and low metastatic tendency. Surgery is the treatment of choice, partial in small limited tumors or total laryngectomy if tumor extends beyond the half of the cricoid and/or is poor differentiated. Although there are some pathognomonic imaging characteristics for chondrosarcomas, the histology remains the gold standard for diagnostic. The authors present a case of large, medium differentiated chondrosarcoma (grade II), surgically treated by total laryngectomy.
