Objectives To evaluate the internal consistency, test-retest reliability, and clinical validity of the Serbian version of the self-administered Voice Handicap Index (VHI)-30. Study Design Cross-sectional study. Methods The English version of VHI-30 was translated into Serbian and then back-translated into English. The Serbian VHI-30 was administered to 91 patients divided into four groups according to voice pathology: structural, inflammatory, neurologic, and functional groups. The control group included 90 subjects with no voice problems. The internal consistency (Cronbach's alpha coefficient α), test-retest reliability (interclass correlation coefficient) of VHI-30, comparison of patient's and control's VHI-30 scores (Mann-Whitney U test; Kruskal-Wallis test), and correlation with overall severity of dysphonia (Spearman correlation coefficient, ρ) were calculated. Results In the patient group, we observed excellent internal consistency for the Serbian VHI-30 (α = 0.95) and good internal consistency for all VHI-30 subscales: physical (α = 0.88), functional (α = 0.88), and emotional (α = 0.88). The interclass correlation coefficient indicated strong test-retest reliability for patients (0.99) and controls (0.84). The mean scores of all 30 items in dysphonic participants were significantly higher than in controls (P < 0.001). Good correlation was obtained between the total scores of VHI-30 and patients’ self-perceived overall severity of dysphonia (ρ = 0.748, P < 0.001). Within the patient group, the female participants displayed significantly higher VHI-30 scores than male participants (Mann-Whitney U test, P < 0.001). The VHI-30 scores showed strong correlation within different patient groups and controls (Spearman correlation coefficient: structural, 0.942; inflammatory, 0.756; neurologic, 0.888; functional, 0.982; controls, 0.882). Conclusions The Serbian VHI-30 is a useful and valuable tool for the evaluation of patients with vocal disorders and for making subsequent clinical decisions. © 2016 The Voice Foundation

Background/Aim. Attic cholesteatoma is an epithelial cystic pseudotumor which arises in the top compartment of the middle ear. Surgery is the only therapeutic treatment for attic cholesteatoma. The aim of this study was to analyze the surgical and audiological results in tympanoplasties that use a logical application of several techniques for the management of attic cholesteatoma. Our hypothesis was that the tympanoplasty technique with cartilage/bone reconstruction of the achieve better outcome than the tympanoplasty technique with only temporal fascia reconstruction of the lateral attic wall. Methods. This retrospective clinical study included 80 patients, aged 16–65 years, with attic cholesteatoma undergoing canal “wall up” tympanoplasty with lateral attic wall reconstruction, under general anesthesia in the Eear, Nose and Throat Clinic, Military Medical Academy in Belgrade between 2006 and 2010. The patients were divided into two groups according to the type of lateral attic wall reconstruction: the group I of 60 patients with cartilage/bone plus temporalis fascia lateral attic wall reconstruction and the group II of 20 patients with only temporal fascia lateral attic wall reconstruction. Postoperative follow-up examinations were done at least 5 years after the surgery. The χ2 test was used to compare postoperative sequelae for two groups of operated patients with lateral attic wall reconstruction. The independent and paired samples t-test of air conduction and air-bone gap were used to compare the results of preoperative and postoperative hearing tests. Results. The differences between hearing measurements of the two groups according to preoperative and postoperative auditory thresholds of the air conduction and the air-bone gap were considered no statistically significant. The difference between the two groups recarding to recurrent attic retraction pocket appearance and recurrence of cholesteatoma was considered statistically significant and the results were much better in the group I of the operated patients with cartilage/ bone lateral attic wall reconstruction. Conclusion. “Wall up” tympanoplasty for attic cholesteatoma with lateral attic wall reconstruction leads to good anatomical and audiological results. A significant hearing improvement was obtained in both the types of lateral attic wall reconstructions in this study. Reconstruction with cartilage or mastoid cortex bone showed favorably long-term functional and anatomical results compared to primary tympanoplasty using only temporal fascia for lateral attic wall reconstruction in cases of attic cholesteatoma. © 2017, Institut za Vojnomedicinske Naucne Informacije/Documentaciju.

Surgical site infection (SSI) is a significant factor of morbidity and mortality in patients surgically treated for laryngeal carcinoma. The aim of this prospective study in 277 patients was to determine the incidence of SSI in patients surgically treated for laryngeal squamous cell carcinoma and to identify risk factors for development of SSI. Patients with previous chemotherapy and/or radiotherapy were excluded. All patients had tracheostomy postoperatively and received antibiotic prophylaxis with cephalosporin, aminoglycoside and metronidazole. The overall incidence of SSIs in our cohort was 6.5% (18 patients): 4 (22.22%) patients with superficial infections, 11 (61.11%) with deep infections and 3 (16.66%) with organ-space infections. The remaining infections included pneumonia (1 case) and Clostridium difficile colitis (2 cases). The median hospital stay in patients having developed SSIs was longer than in those without SSIs (33.5 vs. 16 days, p<0.001). By using univariate analysis American Society of Anesthesiologists score ≥3, duration of surgery longer than 120 minutes and National Nosocomial Infections Surveillance risk index ≥1 were found to be significantly associated with the occurrence of SSI. Age, sex, body mass index, history of smoking, underlying diabetes and preoperative length of stay were found not to be associated with SSI. The most frequently isolated microorganism was Klebsiella spp.
