Objectives: This study aimed to evaluate the diagnostic value of presepsin in differentiating benign and malignant causes of cervical lymphadenopathy and to compare its performance with conventional inflammatory markers, including C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and neutrophil-to-lymphocyte ratio (NLR). Methods: A total of 76 individuals were enrolled, including 52 patients who underwent excisional biopsy for cervical lymphadenopathy and 24 healthy controls. Serum presepsin, CRP, ESR, and complete blood count parameters were measured preoperatively. Patients were classified according to histopathological diagnosis as reactive, granulomatous, or malignant lymphadenopathy. Correlation and receiver operating characteristic (ROC) analyses were performed to assess the diagnostic performance of biomarkers. Results: Median presepsin, CRP, ESR, NLR, and monocyte-to-lymphocyte ratio (MLR) levels were significantly higher in the patient group compared with controls (all p < 0.001). Presepsin levels correlated positively with CRP (r = 0.42), ESR (r = 0.38), and NLR (r = 0.36). Although subgroup analysis revealed no statistically significant differences in presepsin levels among reactive, granulomatous, and malignant cases (p = 0.50), ROC analysis demonstrated the highest diagnostic accuracy for presepsin (AUC = 0.85), followed by CRP (AUC = 0.78), ESR (AUC = 0.74), and NLR (AUC = 0.72). A presepsin threshold of >210 pg/mL predicted malignancy with 82.4% sensitivity and 78.6% specificity. Conclusions: Presepsin provides an objective and noninvasive tool that complements traditional inflammatory markers in the diagnostic evaluation of cervical lymphadenopathy. Its superior diagnostic performance for malignancy prediction suggests potential utility in guiding biopsy decisions and avoiding unnecessary surgical procedures in benign cases.

Background/Objectives: This study aimed to evaluate the relationship between preoperative clinical, ultrasonographic, and cytologic findings and postoperative histopathology in patients with thyroid nodules, and to determine diagnostic factors associated with malignancy. Materials and Methods: A retrospective analysis was conducted on 100 patients who underwent thyroid surgery between September 2012 and April 2014. Preoperative data—including clinical examination, thyroid function tests, and high-resolution ultrasonography—were compared with fine-needle aspiration biopsy (FNAB) results and final histopathology. Ultrasonographic features (echogenicity, calcification, vascularity, and margin) were analyzed for their association with malignancy. Statistical tests included chi-square, t-test, and correlation analysis (p < 0.05 considered significant). Results: Among 100 patients (79 females, 21 males; mean age 47.5 ± 13.9 years), 29 (29%) had benign and 71 (71%) malignant histopathology. Malignancy was significantly associated with older age (p = 0.025), smaller nodule size (p = 0.019), hypoechogenicity (p = 0.001), microcalcifications (p = 0.014), and irregular margins (p = 0.017). FNAB showed a strong correlation with final histopathology (r = 0.65, p = 0.001). The overall sensitivity and specificity of FNAB were 25.4% and 82.8%, respectively. Conclusions: Hypoechogenicity, microcalcifications, and irregular margins were the most reliable ultrasonographic predictors of malignancy. FNAB remains a highly specific but variably sensitive diagnostic tool, and its accuracy increases when interpreted in conjunction with ultrasonographic findings. Integrating cytology with structured imaging systems such as ACR TI-RADS and Bethesda classification enhances diagnostic precision in thyroid nodule evaluation.

Objectives: Tonsillectomy is among the most frequently performed pediatric ENT procedures. Post-tonsillectomy pain and hemorrhage remain key determinants of postoperative morbidity and may differ by surgical technique. This work’s objective is to compare postoperative pain, bleeding, and operative duration across three pediatric tonsillectomy techniques: cold dissection with suturing, cold dissection with ligation, and hot dissection with bipolar cautery. Materials and Methods: In this single-center, prospective study, 150 children (n = 50 per group) undergoing tonsillectomy (with adenoidectomy) between October 2022 and October 2024 were assigned preoperatively to the following groups: Group 1—cold dissection + suturing; Group 2—cold dissection + ligation; Group 3—hot dissection (bipolar cautery). Pain was assessed with the Wong–Baker FACES scale at 1, 6, and 24 h, days 3 and 7, and with the Parents’ Postoperative Pain Measure (PPPM) at 1, 6, and 24 h. Primary bleeding was defined within 24 h; secondary bleeding was within 2 weeks. Operative time was recorded from first incision to hemostasis. Non-parametric tests and chi-square analyses were used with p < 0.05 considered significant. Results: Of 150 patients, 58% were male. No primary hemorrhage occurred. Secondary hemorrhage occurred in 4/150 (2.7%): 1/50 (2%) in Group 1, 0/50 (0%) in Group 2, and 3/50 (6%) in Group 3 (overall p > 0.05). Readmission for oral-intake difficulty occurred in 4/150 (2.7%): 1/50 (2%) in Group 1 and 3/50 (6%) in Group 3 (p > 0.05). Operative time differed significantly across groups (Kruskal–Wallis p < 0.05), being longest in Group 1 and shortest in Group 3 (17.53 ± 1.26 min); Group 2 averaged 18.60 ± 0.94 min and Group 1 21.89 ± 1.64 min. Pain decreased over time in all groups (Friedman p < 0.001). Across virtually all time points, Group 2 (ligation) had significantly lower Wong–Baker and PPPM scores than Groups 1 and 3 (Dunn post-hoc, adjusted p < 0.05), while Groups 1 and 3 did not differ consistently. Conclusions: Cold dissection with ligation yielded the most favorable pain profile while maintaining low bleeding rates; hot dissection minimized operative time but tended toward higher secondary bleeding and postoperative intake difficulties. Technique selection should prioritize postoperative comfort and morbidity reduction—particularly in pediatric populations—favoring cold dissection, with ligation offering a consistent analgesic advantage.

Objectives: This study aimed to evaluate the clinical and hearing outcomes of patients with cholesteatomatous chronic otitis media using the ChOLE classification system and to assess its utility in predicting recurrence, guiding surgical approach, and anticipating hearing recovery. Materials and Methods: This retrospective study included 130 patients (141 ears) who underwent surgery for cholesteatoma between 2011 and 2020. Data were collected from surgical notes, imaging studies, and audiological evaluations. Patients were classified according to the ChOLE criteria, which incorporate cholesteatoma extension (Ch), ossicular chain status (O), and life-threatening complications (L). Surgical procedures and functional outcomes were compared across different stages and classification groups. Hearing outcomes were assessed in the early (3rd month) and late (2nd year) postoperative period. Results: Among the 130 patients (141 ears) evaluated, Stage II was the most common ChOLE stage (74.4%), followed by Stage I (17.7%) and Stage III (7.8%). The most frequently observed cholesteatoma extent was Ch3. A statistically significant association was found between surgical technique and ChOLE stage (p = 0.001): canal wall-down (CWD) tympanomastoidectomy was performed in 91% of Stage III cases and 84% of Stage II cases, whereas 76% of Stage I cases underwent canal wall-up (CWU) procedures. The overall recurrence rate was 29.5% in the CWU group and 16.4% in the CWD group, although this difference did not reach statistical significance (p = 0.792). However, ossicular chain status (O) showed a strong association with both early and late hearing outcomes. At 2 years, conductive hearing success was achieved in 90.9% of O0 patients, compared to 14% of O3b and 0% of O4 patients (p = 0.001). With regard to cholesteatoma extent (Ch), a statistically significant correlation was observed with early air–bone gap (ABG) closure success (p = 0.008) and late air conduction thresholds (p = 0.015). Similarly, ChOLE stage was significantly associated with early conductive hearing success (p = 0.012) and late ABG closure (p = 0.015). Overall, long-term hearing outcomes were superior to early results. Hearing success increased from 19.1% to 24.8% for air conduction thresholds and from 23% to 31.2% for hearing gain when comparing early and late follow-up periods. Conclusions: The ChOLE classification proved useful in guiding surgical strategy and predicting functional outcomes in cholesteatoma surgery. Advanced stage and greater cholesteatoma extension were associated with more extensive surgical procedures and poorer hearing results. Long-term audiological follow-up provided more accurate insights into surgical success. The standardized ChOLE system facilitates consistent reporting and meaningful comparison across institutions and studies.

Objectives: Tinnitus, defined as the perception of sound without an external stimulus, is a complex condition with unclear etiology. Emerging evidence suggests a link between vascular dysfunction, particularly arterial stiffness, and tinnitus. This study aimed to evaluate vertebral artery stiffness in patients with idiopathic subjective tinnitus and assess the utility of Doppler ultrasonography as a non-invasive diagnostic tool. Materials and Methods: In this prospective study, 31 patients with idiopathic tinnitus (11 males, 20 females; mean age: 50.42 ± 9.64 years) and 24 healthy controls (12 males, 12 females; mean age: 39.67 ± 10.63 years) underwent comprehensive clinical evaluations, including pure tone audiometry, blood tests, and vertebrobasilar Doppler ultrasonography. Vertebral artery stiffness index (VAS), resistive index (RI), and pulsatility index (PI) were measured bilaterally. Results: A total of 31 patients with idiopathic subjective tinnitus and 24 healthy controls were evaluated. The mean age was significantly higher in the tinnitus group compared to controls (50.42 ± 9.64 vs. 39.67 ± 10.63 years, p < 0.001). Lipid profile analysis revealed significantly higher levels of total cholesterol (193.6 ± 47.28 vs. 167.5 ± 28.99 mg/dL, p = 0.021), LDL (149.4 ± 37.9 vs. 106.1 ± 10.7 mg/dL, p < 0.005), and triglycerides (202.2 ± 83.5 vs. 148.6 ± 26.4 mg/dL, p < 0.005) in tinnitus patients. Doppler ultrasonography demonstrated significantly higher vertebral artery stiffness values in the tinnitus group (left: 2.87 ± 0.72 vs. 2.12 ± 0.22; right: 2.99 ± 0.77 vs. 2.14 ± 0.5; both p < 0.005). Similarly, pulsatility index (PI) was significantly elevated in patients compared to controls (left: 2.45 ± 1.2 vs. 1.2 ± 0.43; right: 2.49 ± 1.02 vs. 1.19 ± 0.42; both p < 0.005). No significant differences were observed in resistive index (RI) or vertebral artery diameters between groups. Among tinnitus patients, PI and VAS were significantly higher on the side corresponding to reported tinnitus symptoms (p < 0.05), suggesting a lateralized vascular contribution. Conclusions: The findings suggested a potential relationship between idiopathic subjective tinnitus and vertebral artery stiffness. We demonstrated the utility of Doppler ultrasonography, a cost-effective and non-invasive imaging modality, for evaluating vascular parameters in tinnitus patients, paving the way for broader clinical applications. By uncovering a significant association between vertebral artery stiffness and tinnitus, our findings suggest that vascular health assessments could enhance diagnostic and therapeutic strategies for tinnitus management.

The internal auditory canal (IAC) connects the inner ear to the posterior cranial fossa. In this case report, the authors presented an 8-month-old patient with an IAC anomaly and bilateral deafness. The patient has hypotonia and epilepsy, and there is multifocal epileptiform activity on Electroencephalography (EEG). Severe (total) sensorineural hearing loss was detected bilaterally. Temporal bone computed tomography showed that the internal acoustic canal is localized as a single entity at the midline and bifurcates into right and left branches approximately ~4 mm beyond. Following branching, the diameter of each IAC measures approximately ~2 mm. On both sides, inner ear structures are located more medially than normal, positioned close to the midline and each other. Both cochleae undergo approximately 1.5 turns, classified as cochlear hypoplasia type III according to Sennaroğlu and Bajin’s classification. Magnetic resonance imaging showed that in the anterior aspect of the pons, extending from the midline to the internal acoustic canal, a paired appearance, resembling a couple, of the VIII cranial nerve is observed in close proximity to each other. The pair of the VIII nerve seems to diverge at the entrance of the internal acoustic canal, and immediately thereafter, they bifurcate into branches believed to belong to the superior and inferior vestibular nerves on both sides, but the cochlear nerve cannot be discerned.Cite this article as: Akşamoğlu M, Muluk NB, Şahan MH, Leblebici A, Tunç O.

Radiologic findings of fungal sinus disease are generally opacification in paranasal computed tomography (CT) images. The Hounsfield unit (HU) is a standardized objective unit that is also suitable for measuring remodeling and opacifications on CT scans of bone sections of patients with chronic rhinosinusitis. We hypothesized that HU values could provide valuable information in isolated sphenoid sinus lesions before surgery. Between 2012 and 2019, 35 patients underwent functional endoscopic sinus surgery for sphenoid sinus lesions. Tissues obtained from the sphenoid sinus were divided into two groups, fungal and nonfungal, according to the findings of histopathologic examinations. HU values were measured in sphenoid sinus sections on paranasal CT scans of these two groups. Differences in mean and maximum HU values between the two groups were statistically significant (p < .05). The maximum HU values calculated from the sphenoid sinus were 435.08 and 196.23 (p ≤ .05) in the fungal group and nonfungal group, respectively. The mean HU values calculated from the sphenoid sinus were 64.31 and 29 (p ≤ .05) in the fungal and nonfungal groups, respectively. At the maximum cutoff value of 241, the sensitivity and specificity of the HU maximum were 84.6% and 77.3%, respectively. At the mean cutoff value of 41.5, the sensitivity and specificity of the HU mean were 76.9% and 86.4%, respectively. HU is an objective value used in radiographic density measurement. The HU values were higher in fungal lesions than in nonfungal inflammations, and they are useful in preoperative measurement.

Background. Chronic sinusitis and its complications are common in patients with cystic fibrosis. Mucoceles are one of these complications and can have life-threatening consequences if left untreated. Case. We present the case of a giant ethmoid mucocele leading to proptosis and hypertelorism in a 5-year-old child with cystic fibrosis. Conclusion. Chronic sinusitis and its complications are common in patients with CF. Mucoceles are a rare complication of sinusitis that can be treated surgically. As seen in this case if left untreated mucoceles can lead to orbital pathologies such as proptosis, hypertelorism. To the best of our knowledge, we report the first case report of giant ethmoidal mucocele leading to proptosis and hypertelorism in a patient with cystic fibrosis.

Purpose The incidence of Warthin’s tumor (WT) has increased worldwide. In this study, we aimed to evaluate the incidence of WT in our hospital, which provides health care for an extremely large population. Methods We retrospectively evaluated 573 patients, comprising 345 males and 228 females, who all experienced parotid tumor for the past 20 years. Patients with WT that were operated in the last 20 years were evaluated according to the number of patients per year to determine the annual WT increase trend. Results In the distribution of WT over the years of surgery, the ratio of WT to all tumors irregularly changed. Furthermore, the total number of parotidectomies per year increased in time. We investigated whether WT had any increasing trend over the years. The annual percentage change (APC) of WT was calculated, and according to the segmented regression analysis, the APC was insignificant (APC = 4.3, 95% CI = − 3.6–12.9, P = 0.300). Conclusion The incidence of WT has increased across the world. However, in our study, no significant APC was observed according to the segmented regression analysis.
