    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.

    Adenoid cystic carcinoma of the parotid metastasising to the dura fifteen years post primary resection: A case report
    (KARE PUBL, 2020-01-01) Bozkurt, Gulpembe; Jayan, George; Mahmutoglu, Abdullah Soydan
    Adenoid cystic carcinoma (ACC), regardless of the primary site, is typically characterized by a long clinical course associated with a high rate of distant metastases. Intracranial metastasis of ACC is a very rare entity with only few reported cases in the literature. In this study, we report an unusual case of extra-axial intracranial metastasis of ACC in the dura. The primary parotid gland tumour was resected 15 y back. No recurrence had been detected before the occurrence of extra-axial metastasis. After surgical decompression, palliative radiotherapy was administered. To our knowledge, this is the longest interval for the development of metastases following excision of a parotid adenoid cystic carcinoma. This case can raise awareness across specialties that patients with adenoid cystic carcinoma are still at risk of developing metastases even following specialist discharge.

    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.
