    Neck Muscle Mass Index as a Predictor of Post-Laryngectomy Wound Complications
    (SAGE PUBLICATIONS INC, 2018-01-01) Bozkurt, Gulpembe; Elhassan, Hassan Ahmed; Mahmutoglu, Abdullah Soydan; Celebi, Irfan; Mcleod, Robert W. J.; Soytas, Pinar; Erol, Zeynep Nur; Sozen, Esra
    Objective: We investigated the relationship between paravertebral muscle cross-sectional area (PVM CSA) at the third vertebra (C3) level using computerized tomography (CT) neck images and its relationship with complications after total laryngectomy. Design: Retrospective analysis of 60 advanced laryngeal cancer patients who underwent total laryngectomy was performed. The cross-sectional areas of paravertebral neck muscles using neck CT at C3 level images obtained preoperatively were analyzed. Results: A significant difference in PVM CSA between complication and no complication groups, F(1, 53 = 4.319, P = .043), was identified by ANCOVA. There were no significant differences in between-subject effects: T-stage (F = 1.652, P = .204), body mass index (F = 0.889, P = .35), albumin (F = .359, P = .552), age (F = 1.623 P = .208), and smoking (F = 4.319, P = .41). Conclusion: The PVM CSA measured at C3 level on pretreatment CT may help identify patients at higher risk of postoperative wound complications after total laryngectomy and who may particularly benefit from preoperative optimization of nutritional status.

    Multidetector Computed Tomography Findings of Auto-Evacuated Secondary Acquired Cholesteatoma: A Morphologic and Quantitative Analysis
    (AVES, 2018-01-01) Celebi, Irfan; Bozkurt, Gulpembe; Mahmutoglu, Abdullah Soydan; Guliyev, Umman
    OBJECTIVES:To describe and quantify computed tomography (CT) findings of auto-evacuated (spontaneously drained) secondary acquired cholesteatoma (SAC). MATERIALS and METHODS: This multicenter retrospective study included 69 patients with intermittent ear discharge diagnosed with SAC by autoscopy or automicroscopy who were surgically treated. Three independent radiologists measured the medial and lateral attic distance on coronal and axial planes using multidetector computed tomography (MDC T) in 75 ear CTs from 69 patients with intraoperatively verified diagnoses of pars flaccida cholesteatoma (n=36), pars tensa cholesteatoma (n=24), and auto-atticotomy or automastoidectomy (n=15) and compared them with contralateral healthy ears. RESULTS: A circular or elliptical air-tilled cavity surrounded by granulation tissue was morphologically detected on MDCT in these patients. The lateral attic distance was significantly higher in pars flaccida cholesteatoma cases than in contralateral healthy ears on both coronal and axial planes (p<0.05). The medial attic distance was significantly higher in par s ten sa cholesteatoma cases than in contralateral healthy ears in the axial pane, but with no difference in the coronal plane. CONCLUSION: In patients with chronic intermittent aural discharge, nonopacified areas surrounded by granulation tissue, which expands the medial or lateral attic in a CT scan, suggest an auto-evacuated cholesteatoma.

    Tonsillar Plasmacytoma: clues on magnetic resonance imaging
    (BIOMED CENTRAL LTD, 2018-01-01) Celebi, Irfan; Bozkurt, Gulpembe; Polat, Nedim
    Background: Malignant plasma cell proliferation may present as a disseminated disease (multiple myeloma), a solitary plasmacytoma of bone, or an extramedullary plasmacytoma of soft tissue. The latter plasmacytomas represent approximately 3\% of all plasma cell proliferations, and 80\% develop in the head-and-neck region. The unexpected clinical presentation of such masses may be present. Case presentation: Here, we report a rare case of primary tonsillar plasmacytoma in a 42-year-old female. The patient presented with asymmetric tonsillar hypertrophy that was resistant to antibiotherapy. Upon further workup, we found no evidence of multiple myeloma or light-chain disease. The patient underwent surgery and, at the last follow-up, exhibited no evidence of such disease. Conclusions: In adults presenting with asymptomatic tonsillar enlargement, the possibility of submucosal masses should be considered, thus encouraging the radiologist to evaluate crypts within the palatine tonsil on a postcontrast MRI, besides enlargement and signal change.
