Backgroud/Objectives: Transoral laser laryngeal microsurgery (LTLM) has been widely used in the treatment of early-stage glottic laryngeal squamous cell carcinoma (LSCC) for the past few decades. Although T stage, tumor grade, anterior commissure involvement, type of cordectomy, positive surgical margin, and postoperative additional therapies were accused as the prognostic factors for recurrence, there is still controversy about these data in the literature. The purpose of this study was to evaluate the oncological results of our patients with early glottic LSCC treated with LTLM as a single-modality therapy in a single-center study. Methods: Patients with early-stage (Tis-1–2/N0) glottic LSCC who underwent LTLM as a primary treatment from 2011 to 2019 were retrospectively reviewed. The clinicopathological factors and oncologic outcomes were analyzed. Results: One hundred and sixty-one patients were enrolled in this study. The 5-year overall (OS), disease-specific (DSS), disease-free (DFS), and laryngectomy-free survival rates were 84.5%, 97.9%, 79.2%, and 93.5%, respectively. The most common stage, histopathological type, and type of endoscopic cordectomy were T1 stage, well-differentiated cancer, and type 2 cordectomy, respectively. A positive surgical margin was defined in 20 (12.4%) patients. There was a significant relationship between histopathological grade and positive surgical margins (p = 0.038). OS and DSS rates of “wait and see” modality were lower, while DFS of radiotherapy was lower than that of other treatment modalities in patients with positive surgical margins, but the differences were not statistically significant. Nineteen (11.8%) patients had a recurrence. DSS was statistically significantly lower in patients with recurrence (p < 0.001). Conclusion: The results of our study showed that anterior commissure involvement, surgical margin positivity, and higher T stage statistically did not reduce survival rates in early-stage LSCC patients treated with LTLM. As the histopathological grade of the tumor worsens, the risk of surgical margin positivity increases. RT may have a negative effect on recurrence and organ preservation in the additional treatment of patient with positive surgical margins.

Objective: To reveal the incidence and predictive parameters of occult cervical lymph node metastasis (LNM) in patients with cN0 laryngeal squamous cell cancer (LSCC) who underwent surgery as definitive treatment. Methods: Patients with cN0 laryngeal cancer who had undergone elective neck dissection together with partial or total laryngectomy between January 2006 and November 2020 were retrospectively analyzed. Clinical and histopathologic predictors of occult metastasis were also analyzed. Follow-up data were used to obtain recurrence and survival analysis. Results: A total of 86 patients with a mean age of 62.5 years were included in the study. Occult LNM was detected in 15 (17.4%) patients. Tumor grade, pT stage, thyroid cartilage invasion, and extralaryngeal extension were found to predict occult neck metastasis in univariate analysis. The mean follow-up time was 60.7 months and in the survival/recurrence analysis, pT stage, tumor location, tumor grade, presence of occult metastasis, pre-epiglottic space involvement. and extralaryngeal extension were found to predict poorer outcome. Conclusion: Overall occult LNM is low (17.4%) in N0 laryngeal cancer, but the presence of LNM is a poor prognostic factor. Correct determination of the neck status and proper treatment is crucial. The incidence of LNM is very low in T1–T2 stages and well-differentiated tumors. The “wait and see” strategy may be applied in T1–T2 cases as well as selected T3 cases with well-differentiated tumors.

This study aimed to analyze laboratory and radiological imaging results in the prediction of treatment strategy in patients with deep neck infections. Eighty-three patients (55 (66.3%) men, mean age: 38.2±14.5 years) were included in the study. Patients were divided into three groups according to the treatment strategy: group 1 received only antibiotic treatment, group 2 underwent abscess drainage with needle puncture in addition to antibiotic treatment, and group 3 underwent surgical drainage with antibiotic treatment. Laboratory outcomes, imaging methods, duration of hospital stay, treatment strategy, and clinical outcomes were analyzed.According to the laboratory results, complete blood count values did not vary among the three groups, but C reactive protein (CRP) and erythrocyte sedimentation rate (ESR) values were higher in group 3 (p

Upregulation of the epidermal growth factor receptor (EGFR) gene has shown an important impact on the development of head and neck cancers due to its important regulation role on multiple cell signaling pathways. The aim of this study was to investigate the methylation pattern of the promoter region of the EGFR gene between head and neck squamous cell carcinoma (HNSCC) patients and a control group. Forty-seven unrelated HNSCC patients, clinically diagnosed at the Department of Otorhinolaryngology, Dışkapı Yıldırım Beyazıt Training and Research Hospital, Ankara, Turkey, and 48 unrelated healthy volunteers from different geographic regions of Turkey, were included in this study. Methylation status of the promoter region of the EGFR gene was detected by methylation-specific-polymerase chain reaction (MS-PCR). The correlation between EGFR gene promoter methylation profiles and clinical characteristics were examined using the χ2 test. Methylation was observed in 79.0% of HNSCC patients, whereas this ratio was 90.0% in healthy individuals. The results show that promoter region methylation of the EGFR gene was not associated with HNSCC development in the studied Turkish patient group. In addition, the methylation status of the EGFR gene promoter was not found to be related to age, gender or tumor stage.

Background/aim We aimed to revealthe incidence and predictive role of insulin resistance and distorted oral glucose tolerance test in nondiabetic patients withBell’s Palsy (BP). Materials and methods Eighty-sixpatients with BP and 28 control subjects; all with normal blood glucose levels and no history of diabetes, were enrolled in the study. We investigated insulin resistance (IR) in all subjects, in terms of HOMA-IR greater than 2.7. Sixty-two of the patients also underwent an oral glucose tolerance test (OGTT). Results The mean HOMA-IR value was significantly increased in patients, compared to the control group (3.2 vs 1.6; P < 0.01). IR was detected more in BP patients than in controls (P < 0.05). The patients with higher HOMA-IR values had more severe facial dysfunction at the initial presentation and complete recovery time took longer than the patients with normal HOMA-IR value (75 days vs 42 days; P < 0.05). Following a 2h-OGTT, impaired glucose tolerance and newly diagnosed DM were found in 60% of the patients. Recovery time was significantly longer in prediabetics and newly diagnosed diabetic patients than in patients with normal glycemia (68 days, 52 days, and 32 days, respectively; P < 0.01). Conclusion There is a strong linkage between HOMA-IR value and BP prognosis so HOMA-IR value may have a significant role of predicting BP prognosis at presentation.

Objectives: The purpose of this study was to investigate relation between mean platelet volume, platelet distribution width, platelet-to-lymphocyte ratio, neutrophil-to-lymphocyte ratio and vestibular migraine. Methods: This study was planned in prospective manner and conducted in Ankara Polatlı State Hospital between April 2017 and May 2018. Thirty patients diagnosed with vestibular migraine and thirty healthy, age and sex-matched subjects were enrolled to the study. Mean platelet volume, platelet distribution width, platelet count, neutrophil count and lymphocyte count in blood samples were measured. Results: The mean age of the patients with vestibular migraine was 39.90 ± 7.16 and the study group consisted of 11 males and 19 females. The mean platelet volume and platelet distribution width values in patients with vestibular migraine were significantly higher than the control group (p < 0.001). There were no difference on mean neutrophil/lymphocyte ratio and platelet/lymphocyte ratio values between patient group and control group. Conclusions: We found a positive relation of increased levels of mean platelet volume and platelet distribution width with vestibular migraine. Higher mean platelet volume is associated with atherosclerosis and thromboembolism. Vascular pathologies are blamed for both headache syndromes like migraine and vertiginous syndromes. This theory supports our study but pathophysiological mechanism is not clear.

Understanding the molecular mechanisms and gene expression in laryngeal squamous cell carcinoma (LSCC) may explain its aggressive biological behavior and regional metastasis pathways. In the present study, patients with locally advanced LSCC tumors were examined for differential gene expression in the normal mucosa (non-tumoral mucosa), tumors and lymph node tissues. The aim was to identify possible predictive genes for lymph node metastasis. A total of 16 patients who had undergone total laryngectomy with neck dissection for advanced LSCC were randomly selected from a hospital database: Eight of the patients had lymph node metastasis (Group 1) and the other eight patients did not have metastasis (Group 2). Overall survival (OS), disease-free survival (DFS) and disease-specific survival (DSS) were analyzed. For each patient, paraffin-embedded tissue samples were collected from non-tumoral mucosa, tumoral lesions and lymph node tissues. RNA was extracted from the tissue samples and used for complementary DNA synthesis, and microarray analysis was subsequently performed on each sample. Gene expression levels were determined in each specimen, and Groups 1 and 2 were compared and statistically analyzed. The microarray results for lymph node metastasis-positive and -negative groups, indicated the differential expression of 312 genes in the lymph nodes, 691 genes in the normal mucosal tissue and 93 genes in the tumor tissue. Transgelin (TAGLN) and cofilin 1 (CFL1) were identified as possible target genes and validated using reverse transcription-quantitative polymerase chain reaction (RT-qPCR). The RT-qPCR results for TAGLN and CFL1 supported the microarray data. OS, DFS and DSS times were longer in Group 2 than in Group 1 (P=0.002, 0.015 and 0.009, respectively). In addition, TAGLN and CFL1 were associated with DFS and DSS. On the basis of these results, it is suggested that TAGLN and CFL1 expression may play an important role in the pathogenesis of regional metastasis and poor prognosis in advanced LSCC.

It is aimed to present endovascular treatment of carotid blowout syndrome (CBS) in patients with head and neck cancer. A retrospective review was performed on patients with carotid blowout syndrome between 2012 and 2018 in our hospital. A total of ten patients with prior history of head and neck cancer surgery and radiation therapy were investigated with clinical, postoperative and follow-up findings as well as technical outcome. Digital subtraction angiography of the carotid arteries was performed in all the cases for the diagnosis of the source of bleeding. Detachable coils and covered stents were used in endovascular treatment of carotid blowout syndrome. After the procedures, all patients were admitted to the intensive care unit for the follow-up of both hemodynamic and neurologic conditions. Thirteen diagnostic and endovascular treatment sessions were performed in 10 patients. Seven patients had major surgery for head and neck cancer and all patients were treated with chemoradiotherapy. Head and neck cancers in seven of the ten patients were persistent and pharyngocutaneous fistula developed in five patients. Two patients had impending CBS and eight patients had acute CBS. A total number of 19 vascular lesions in 10 patients were detected and 4 patients had multiple lesions. In three patients, additional endovascular treatment of stent-graft deployment had required due to recurrent hemorrhage after a mean time of 5.33 days (range 1–11 days). As a conclusion, covered stent application with or without coil embolization is a safe and efficient technique in treatment of CBS secondary to head and neck cancers.

11th International Ear Nose Throat Diseases and Head and Neck Surgery Congress -- APR, 2014 -- -- Ankara, TURKEY, WOS: 000458367000031, PubMed: 30761884, Backround/aim: Papillary thyroid carcinomas (PTC) frequently metastasize to regional lymph nodes. Our purpose was to investigate the predictive role of tumor location for lymph node metastasis pattern in PTCs. Materials and methods: Medical records of 110 PTC patients were reviewed retrospectively. Tumor location was determined as upper, middle, and lower pole according to ultrasonography (USG) findings. The effects of age, sex, tumor size, and location on lymph node metastasis were investigated. Results: The series comprised 87% females (n = 96) and 13% males (n = 14). Forty-three patients had central neck metastasis (CNM) and 14 had lateral neck metastasis (LNM). Upper pole tumors (UPT) metastasized to the central neck (CN) at a lower rate (17.6%) than middle (40.0%) or lower (48.5%) poles overall (P = 0.104), while it was at a significantly lower rate (13.3%) in the PTC group (P < 0.05). UPTs (n = 17) metastasized to the lateral neck (LN) almost 2-fold more. It was observed that 3 of 4 UPTs spread directly to the LN without CNM. Conclusion: In our opinion, UPTs have propensity to demonstrate metastasis to LN rather than the CN in PTCs. Therefore, UPTs should be evaluated meticulously in terms of LNM. New studies could suggest that CN dissection is not performed for low-risk PTCs in UPTs.

Head and neck cancer (HNC) is one of the most common malignancies in the world. HNC is a group of cancers that starts in the mouth, nose, throat, larynx, sinuses, or salivary glands. According to this section of the body parts; induction of cancer can be associated with CO2 and oxidative stress. The aim of this study is to assess the activities of carbonic anhydrase (CA), catalase (CAT), paraoxonase1 (PON1), and xanthine oxidase (XO) activities in 89 HNC patients and 115 healthy volunteers. Paraoxonase1 activity was found lower in HNC cancer patients. There is no statistically significant difference between patients and controls for catalase, carbonic anhydrase, and xanthine oxidase enzyme levels. According to this results, paraoxonase1 levels could be a candidate as an oxidative marker in HNC patients, but further studies are needed to investigate the other type of cancer related PON1 and the other enzyme levels.

Background/aim To evaluate the clinical and histopathological effects of fetal brain tissue derived mesenchymal stem cells (FBTMSC) and fibrin glue (FG) on the facial nerve (FN) regeneration in rats with traumatic FN injury. Materials and methods Twenty-eight Sprague Dawley rats were included in the study and divided into 4 groups. Traumatic FN injury (FP) was created by a surgical clamp compression to the main trunk of left FN in all groups. In the control group (group 1) no treatment was applied, in group 2 (FBTMSC group) 2 × 106 FBTMSC was injected, in group 3 (FG group) only FG was applied, in group 4 (FBTMSC and FG groups) both FBTMSC and FG were applied to the injured section of the nerve. The FN functions were evaluated clinically, immediately after the procedure and at 3rd, 5th, and 8th weeks postoperatively. The FNs of all subjects were excised after the 8th week; then the rats were sacrificed. The presence of stem cells in the injured zone was assessed using bromo-deoxyuridine (BrdU), and apoptosis was determined by the TUNEL method. Results After the damage, total FP was observed in all subjects. Statistically significant functional improvement was observed in group 4 compared to all other groups (P < 0.005). TUNEL-positive cell count was statistically significantly higher in the control group than the other groups (P < 0.001). TUNEL-positive cell count was statistically significantly lower in group 4 than the other groups. The proportion of BrdU-stained cells in group 4 (5%) was higher than group 2 (2%). Conclusion Clinically and histopathologically FBTMSC applied with FG may play a promising role as a regenerative treatment in posttraumatic FP.

Background/aim This study aims to determine the therapeutic superiority of the addition of intratympanic steroid or hyperbaric oxygen therapy to systemic steroid treatment in idiopathic sudden sensorineural hearing loss as initial treatment, and evaluate the long- term results of salvage treatment. Materials and methods This study was a retrospective clinical trial with a total of 96 patients with idiopathic sudden sensorineural hearing loss. Patients were divided into 3 groups. Group 1 (n: 32) received systemic steroid treatment. Group 2 (n: 32) received the Group 1 protocol plus intratympanic steroid treatment. Group 3 (n: 32) received the Group 1 protocol plus hyperbaric oxygen treatment. Pretreatment and postinitial audiologic evaluations were performed, and the hearing outcome was analyzed with Furuhashi criteria. All patients, except those who experienced total recovery after initial treatment, were directed to salvage treatment. Audiologic assessment was performed again after salvage treatment and a mean follow-up period of 36.5 months. Results Each group was homogenous according to demographics, audiologic data, and prognostic factors. There was no statistically significant difference in recovery and success rate within the 3 groups after initial treatment. (P: 0.66, P: 0.248, respectively). Successful results were obtained after salvage treatment in only 3 patients (5%). These patients received follow-up treatment at a mean of 36.5 months, but there was no spontaneous recovery after the end of salvage treatment. Conclusion The addition of intratympanic steroids or hyperbaric oxygen to systemic steroids caused no significant hearing improvement as the initial treatment of idiopathic sudden sensorineural hearing loss. The efficacy of salvage treatment was limited, and there was no spontaneous hearing improvement after the long-term follow-up.

Objectives The majority of thyroid nodules are discovered incidentally, and the management may be a challenge if the fine needle aspiration specimen yields indeterminate findings. Our aim was to develop an individualized risk prediction model to provide an accurate estimate of cancer risk in patients with cytologically indeterminate thyroid nodules. Materials and methods Clinical records, ultrasound images, and cytopathology reports of patients who underwent thyroidectomy were retrospectively reviewed. Logistic regression analysis was used to identify the predictive ability of each variable for malignancy, and a nomogram was built by integrating patients' age, multiplicity of nodules, cytology results, and suspicious ultrasound features, such as microcalcifications and irregular margins. Results For the 233 indeterminate nodules according to the Bethesda System for Reporting Thyroid Cytopathology, the malignancy rates of the subgroups "atypia of undetermined significance," "suspicious follicular neoplasia," and "suspicious for malignancy" were 44.3, 47.7, and 88.0%, respectively. It was found that the Bethesda category "suspicious for malignancy," microcalcifications, and irregular margins were independent risk factors for malignancy. The area under the receiver operating characteristics curve was 0.784, which suggested that the presented nomogram had considerable discriminative performance. Conclusions The nomogram developed in our study accurately predicts the malignancy risk of thyroid nodules with indeterminate cytology by using clinical, cytological, and ultrasonographic features.

Objectives: This study aims to investigate the therapeutic effect of low-dose topical administration of methotrexate MTX in a toluene diisocyanate TDI -induced allergic rhinitis rat model. Materials and Methods: The experiments were performed on 18 healthy male Wistar albino rats weighing between 250-270 g. Rats were divided into four study groups: control group n=5 , sham group n=3 , steroid group n=5 , and MTX group n=5 . After the drugs were administered, multiple biopsies were taken bilaterally from the nasal mucosal areas and evaluated histologically for fibrosis, loss of cilia and goblet cells, edema, squamous cell metaplasia, and vascular proliferation. Results: Fibrosis, loss of cilia cells, edema, and vascular proliferation were significantly lower in both MTX and steroid groups than in the control group p0.05 . There were no statistically significant differences with respect to loss of goblet cells and squamous cell metaplasia among the studied groups p>0.05 . Conclusion: Methotrexate may be an alternative or adjuvant therapeutic agent in allergic rhinitis.

Background To analyze protective/regenerative effects of adipose tissue-derived mesenchymal stem cells (ADMSC) on 131I-Radioiodine (RAI)-induced salivary gland damage in rats. Materials and Methods Study population consisted of controls (n:6) and study groups (n:54): RAI (Group 1), ADMSC (Group 2), amifostine (Group 3), RAI+amifostine (Group 4), concomitant RAI+ADMSC (Group 5) and RAI+ADMSC after 48 h (Group 6). We used light microscopy (LM), transmission electron microscopy (TEM), and salivary gland scintigraphy (SGS), and analyzed data statistically. Results We observed the homing of ADMSC in salivary glands at 1st month on LM. RAI exposure affected necrosis, periductal fibrosis, periductal sclerosis, vascular sclerosis and the total sum score were in a statistically significant manner (P < 0.05). Intragroup comparisons with LM at 1st and 6th months revealed statistically significant improvements in Group 6 (P < 0.05) but not in Groups 4 and 5. Intergroup comparisons of the total score showed that Groups 4 and 5 in 1st month and Group 6 in 6th month had the lowest values. TEM showed vacuolization, edema, and fibrosis at 1st month, and an improvement in damage in 6th month in Groups 5 and 6. SGSs revealed significant differences for the maximum secretion ratio (Smax) (P = 0.01) and the gland-to-background ratio at a maximum count (G/BGmax) (P = 0. 01) at 1st month, for G/BGmax (P = 0.01), Smax (P = 0.01) and the time to reach the maximum count ratio over the time to reach the minimum count (Tmax/Tmin) (P = 0.03) at 6th month. 1st and 6th month scans showed differences for Smax and G/BGmax (P = 0.04), but not for Tmax/Tmin (p > 0.05). We observed a significant deterioration in gland function in group 1, whereas, mild to moderate deteriorations were seen in protective treatment groups. Conclusions Our results indicated that ADMSC might play a promising role as a protective/regenerative agent against RAI-induced salivary gland dysfunction.

Defects in mucosal healing after sinonasal surgery cause infection, scar formation causing obstruction, relapse of the disease within a shorter period and revision surgery. The present study aimed to create a functional ciliated epithelium using a stem cell and stem cell sheet of adipose tissue origin and to show such regeneration ultra-structurally on experimentally injured rabbit nasal epithelium. This was an experimental animal study and basic research. A total of 18 white New Zealand rabbits were divided into three groups. The medial wall of the maxillary sinus of the subjects was peeled off bilaterally. No additional procedure was applied to the subjects in Group 1. In Group 2, adipose tissue-derived mesenchymal stem cell was implanted on the wound edges of the subjects. In Group 3, a stem cell sheet of three layers was laid onto the defect area. All subjects were killed after 3 weeks. The presence of the stem cell stained with bromo-deoxyuridine was assessed with a light microscope, whereas cilia density, ciliated orientation and cilia structure were evaluated with a scanning electron microscope. Ciliary densities in Group 2 and Group 3 were statistically superior compared to the control group (p

Objective To evaluate the feasibility and value of sonoelastography in assessing non-thyroid neck masses. Methods Non-thyroid neck masses requiring surgical interventions were evaluated using conventional B-mode ultrasonography (US) (size, short/long axis rate, shape, hilum, echogenity, calcification, necrosis, and peripheral edema) and sonoelastograpy (SE) with strain ratio (SR) and elasticity score (ES) before surgery. These parameters were compared with the histopathological examination. Results In total, 116 non-thyroid neck masses (66 lymph node, 35 parotid gland, eight submandibular gland, and seven cervical mass) of 89 patients (51 men, 38 women) with a mean age of 50.3±15.1 (19-79) years were evaluated. Thirty-seven malignant lymph nodes (23 metastatic and 14 lymphoma), seven malignant parotid tumors, two malignant submandibular tumors, 29 benign lymph nodes, 28 benign parotid lesions, and six benign submandibular lesions were evaluated. Mean SR and ES values of malignant masses were 6.3/3.2 for lymph nodes, 5.5/3.3 for the parotid gland, and 4.2/3 for the submandibular gland. Mean SR and ES values of benign lesions were 2.0/2.1 for lymph nodes, 4.4/3.2 for the parotid gland, and 3.2/3 for the submandibular gland. SR and ES were significantly higher for malignant masses compared with those for benign ones. SR was more predictive than ES in evaluating malignant lymph nodes. The area under the curve was 0.917(0.827-1.00) (p

Dysphagia and pain are most common problems after soft palate surgery in obstructive sleep apnea (OSA) patients.The aim of this study was to compare the postoperative pain scores and presence of dysphagia in patients who underwent anterior palatoplasty (AP) or uvulopalatal flap (UPF) surgeries.In this prospective study, AP or UPF was performed on the patients with mild or moderate OSA. Daytime sleepiness of all patients was evaluated with Epworth sleepiness scale (ESS). Snoring, pain and dysphagia complaint of the patients was evaluated with visual analog scale (VAS).In both AP and UPF groups, VAS snoring and ESS scores decreased significantly after operation. VAS pain and dysphagia scores were determined to be significantly higher in UPF compared with the AP.Since the success rates of surgical interventions to the soft palate are similar, preferring surgical approaches with a less damage to the life quality of patients after operations is more rational. In this regard, AP, which is technically quite simple with a short operation time and fewer postoperative complaints affecting life quality such as pain or dysphagia may be preferred in selected patients with OSA.

Small interfering RNA (siRNA)-based gene silencing strategy has high potential on suppressing specific molecular targets, involved in cancer progression. However, the lack of an effective nanocarrier system that safely delivers siRNA to its target still limits the clinical applications of siRNA. This study aimed to develop albumin-sericin nanoparticles (Alb-Ser NPs) as a novel siRNA delivery system for laryngeal cancer treatment. Nanoparticle formulations composed of albumin and sericin at different ratios (1:1, 2:1, 1:2 w/w) were synthesized by desolvation method. The nanoparticles were modified with poly-L-lysine (PLL) for siRNA binding and decorated with hyaluronic acid (HA) to target laryngeal cancer cell line, Hep-2. HA/PLL/Alb-Ser NPs were individually loaded with siRNAs for casein kinase 2 (CK2), Absent, Small, or Homeotic-Like (ASH2L), and Cyclin D1 genes, which are overexpressed in Hep-2 cells. Downregulation of genes was confirmed by real-time PCR (RT-PCR). Size, morphological, and thermogravimetric characterizations revealed that Alb-Ser NPs having 2:1 (w/w) ratio are the most optimized formulation. Between 36.8 and 61.3% of siRNA entrapment efficiencies were achieved. HA/PLL-siRNA/Alb-Ser (2:1) NPs-mediated gene silencing resulted in a significant inhibition of cell growth and induction of apoptosis in cells. Our findings showed that HA/PLL/Alb-Ser (2:1) NPs were promising as a siRNA carrier.

Objectives/Hypothesis To investigate the effects of anterior palatoplasty on the presence and stage of floppy eyelid syndrome (FES) among patients diagnosed with mild or moderate obstructive sleep apnea (OSA) according to the apnea-hypopnea index (AHI). Study Design Prospective controlled trial. Methods Those patients whose AHI scores were between 5 and 30 according to full-night polysomnography were included in the study. The patients in whom anterior palatoplasty was performed were included in the study group, whereas those refusing surgery comprised the control group. All patients were evaluated for the presence of FES. The sleep studies were repeated after the third postoperative month, and the results were statistically compared. Results Sixty-two patients were included in the study. Thirty-five patients who were treated with anterior palatoplasty comprised the study group, and 27 patients were included in the control group. In the surgically treated group, 60% (n = 21) had FES, whereas 55.5% (n = 15) of the control group had FES (P = .798). In the surgically treated group, the FES ratio decreased to 25.7% (n = 9) after the third postoperative month (P = .007). In surgically successful cases, the preoperative–postoperative oxygen desaturation index and preoperative–postoperative lowest oxygen saturation values were 11.755% ± 9.037% and 6.77% ± 5.362% (P = .04), and 86.1% ± 3.89% and 87.8% ± 2.85%, respectively (P = .124). These values were 12.166% ± 5.767% and 14.780% ± 9.924% (P = .385), and 86.13% ± 4.18% and 85.26% ± 4.26%, respectively (P = .579), in patients who underwent unsuccessful surgery. Conclusions FES presence and stages were decreased following successful anterior palatoplasty surgery. This effect may have resulted from the correction of tissue hypoxia, which is common in the pathophysiology of both OSA and FES. Level of Evidence 2b Laryngoscope, 2016

The aim of this case report is to demonstrate a very rare coincidental existence and management of the Killian-Jamieson diverticulum during thyroid surgery in a patient with dysphagia. An 18-year-old female patient with the complaints of progressive dysphagia and a rapidly growing mass at the anterior cervical region was undergone thyroid lobectomy. Coincidentally, a 2×2 cm Killian-Jamieson diverticulum was observed and simultaneously excised with the thyroid lobe, preserving the recurrent laryngeal nerve. Dysphagia is a frequent symptom, especially in patients with a rapidly growing thyroid mass. Thyroid surgeons should keep in mind that hypopharyngeal and upper esophageal pathologies can mimic the symptoms of a thyroid mass; therefore, detailed imaging techniques should be used for the differential diagnosis.

Development of thyroid nodule during pregnancy is rare, however the cancer rate of this nodule is high. Herein, we present medical outcomes of three pregnant women who were operated with the diagnosis of differentiated thyroid carcinoma in the light of literature. As sonographic findings of three cases showed malignant characteristics, fine needle aspiration biopsy (FNAB) was performed. Cytological examination result was reported as papillary thyroid carcinoma (PTC). Surgery was performed in the second trimester in all cases. One case underwent total thyroidectomy with neck dissection at level III and VI and two cases underwent total thyroidectomy with neck dissection at level VI. Pathological examination result was also reported as PTC. Lymph node metastases in the dissected materials were detected. During the intraoperative and early postoperative period, no complications occurred and no findings of recurrence or residues were observed during one-year follow-up following surgery. In conclusion, as the first trimester has an increased risk of congenital malformations, elective surgery should be performed at the second trimester, if applicable. In pregnants with malignant sonographic features and PTC confirmed by FNAB, surgery can be applied safely by taking precautions during pre-/peri- and postoperative period. These patients should not be given premedication for anesthesia, should be properly positioned and teratogenic agents should be avoided. After surgery, mother and fetus should be monitored closely.

The aim of choanal atresia (CA) surgery is to achieve bilateral nasal patency. Among the different methods of CA repair, the endoscopic transnasal approach has gained recent popularity with the advent of endoscopic instruments and techniques. This article describes our experience regarding CA repair that was done either using or not using a stent in different periods of time in our department. Between February 2006 and February 2016, a total of 29 patients aged 2 days–53 years underwent endoscopic transnasal CA repair. While in early years stents were used to maintain nasal patency, since 2010, all cases were repaired endoscopically without stenting. Of the 29 patients, 8 were excluded because of inadequate follow-up data. The mean follow-up time for the remaining 21 patients after surgery averaged 53 months (range 12–111 months). Intranasal stents were used in 5 of 21 patients for 8 out of 32 operative sides. Of the 8 stented neochoanae, 6 (75%), restenosed at a mean time of 15.2 weeks (5–24). The restenosis rate was 25% (6/24 nasal sides) in 16 patients who underwent stentless repair. In unilateral CA, 2 of 10 (20%) patients underwent atresia repair using stents and only these cases restenosed after surgery in this group. Of the 11 patients with bilateral disease, 5 (45.4%) underwent revision surgeries. In the bilateral group, 2 of 3 (66.6%) stented patients required revision surgeries, whereas 3 of 8 (37.5%) patients who underwent stentless repair relapsed. In one patient, we have experienced an alar cartilage injury intraoperatively caused by drilling. The transnasal endoscopic repair has proved to be effective and yielded long-term satisfactory results. The use of stent seems to have no advantage over a stentless repair regarding maintenance of a patent nasal airway. Patients experienced restenosis more frequently with stenting.

Bayir, Omer/0000-0001-9445-6129 WOS: 000435637700012 Aim: Facial canal dehiscence (FCD) is the most important consideration in the cholesteatoma surgery. The tympanic portion is the most common localization of FCDlization in the majority of cases. MDCT is the standardt imaging modality for temporal bone screening. In this study we aimed to compare coexisting the radiological and - surgical findings of patients who have were found during surgery to have FCD in surgery. Material and Method: We examined retrospectively 351 patients with cholesteatoma who have been were operated on between April 2011 and April 2016. In terms off or this study FCD, we compared the preoperative temporal bone MDCT and the surgery findings of 64 patients with FCD. Results: Positive surgical findings included external auditory canal (EAC) destruction (31.2%), FCD (100%), aditus ad antrum widening (A) (57.8%), ossicular erosion (96.8%), lateral semicircular canal (SSC) defect (18.7%), superior semicircular canal (SSSC) defect (1.5%), and cochlear defect (4.6%). Temporal bone MDCT positive findings included EAC destruction (37.5%), FCD (93.7%), A (82.8%), ossicular erosion (96.8%), SSC defect (18.7%), superior semicircular canal (SSSC) defect (6.2%), and cochlear defect (4.6%). The maximal precision of MDCT imaging in this study was in defining FCD (93.7%), A (82.8%), ossicular erosion (96.8%), and scutum destruction (68.7%). Surgical and CT findings of ossicular chain erosions, A, and SCC fistula showed positive relations inwere positively correlated correlation analyses (p-0.001). Discussion: The significant correspondence between MDCT and clinical findings indicates that MDCT may lead to better a diagnosis of probable likely problems before cholesteatoma surgery, and and to a higherimproves the success rate of cholesteatoma those surgeries. The combined analysis of multi-planar imaging improves the positive diagnosis rate of FCD, especially ion the tympanic portion.

An acute transient sialadenitis of the major salivary glands in the early postoperative period is called ‘anesthesia mumps’. It has been reported in different surgical procedures especially in neurosurgical procedures. Anesthesia mumps develops very fast after the extubation period but it usually regresses with no sequelae within a few hours. However, sometimes serious complication can occur such as respiratory distress. In this report, we present a 3-year-old girl with an anesthesia mumps and facial palsy occurring after successful auditory brainstem implantation and we discuss the cause and the management of this rare complication in this report.

Background/aim: The aim of this study was to investigate alterations in voice parameters among patients using continuous positive airway pressure (CPAP) for the treatment of obstructive sleep apnea syndrome. Materials and methods: Patients with an indication for CPAP treatment without any voice problems and with normal laryngeal findings were included and voice parameters were evaluated before and 1 and 6 months after CPAP. Videolaryngostroboscopic findings, a self-rated scale (Voice Handicap Index-10, VHI-10), perceptual voice quality assessment (GRBAS: grade, roughness, breathiness, asthenia, strain), and acoustic parameters were compared. Results: Data from 70 subjects (48 men and 22 women) with a mean age of 44.2 ± 6.0 years were evaluated. When compared with the pre-CPAP treatment period, there was a significant increase in the VHI-10 score after 1 month of treatment and in VHI- 10 and total GRBAS scores, jitter percent (P = 0.01), shimmer percent, noise-to-harmonic ratio, and voice turbulence index after 6 months of treatment. Vague negative effects on voice parameters after the first month of CPAP treatment became more evident after 6 months. Conclusion: We demonstrated nonsevere alterations in the voice quality of patients under CPAP treatment. Given that CPAP is a long-term treatment it is important to keep these alterations in mind.

Background Obstructive sleep apnea (OSA) has been shown to be associated with atrial fibrillation (AF). Prolongation of inter- and intraatrial conduction times during sinus rhythm has also been shown to be related to AF generation. Nasal continuous positive airway pressure (CPAP) is an effective treatment modality of OSA. Methods Twenty-four OSA patients diagnosed through polysomnography and 18 controls were included in the study. The basal inter- and intraatrial electromechanic delays prior to onset of the therapy were measured using tissue Doppler imaging. P-wave dispersion (Pd) was calculated on the basis of 12-lead electrocardiography. Same measurements were performed in OSA patients 6 months after the initiation of the therapy. Results Interatrial (39.2 ± 8 vs. 21.1 ± 2.8 ms, P < 0.001), left intraatrial (20.5 ± 7.2 vs. 11.1 ± 2 ms, P = 0.003), and right intraatrial electromechanical delays (20.7 ± 11 vs. 10 ± 2.6 ms, P < 0.001) prior to CPAP therapy were found to be significantly greater in OSA group as compared with the controls. Pd was also greater in the OSA group as compared with the controls (44 ± 7 vs. 28.5 ± 4 ms, P < 0.001). However, significant improvement has been noted after 6 months of CPAP therapy in interatrial (P < 0.0001), left intraatrial (P = 0.002), and right intraatrial electromechanical delays (P < 0.0001) as well as in Pd (P < 0.0001) as compared to baseline values in patients with OSA. Conclusion Our findings suggested that CPAP therapy provides more homogenous conduction through atria in patients with OSA. This effect may translate into decreased risk for AF associated with OSA.

Vestibular-evoked myogenic potentials (VEMP), short-latency electromyographic responses elicited by acoustic stimuli, evaluate the function of vestibulocollic reflex and may give information about brainstem function. The aim of the present study is to evaluate the potential contribution of VEMP to the diagnosis of multiple sclerosis (MS). Fifty patients with MS and 30 healthy control subjects were included in this study. The frequency of VEMP p1-n1 and n2-p2 waves; mean p1, n1, n2, and p2 latency; and mean p1-n1 and n2-p2 amplitude were determined. The relation between clinical and imaging findings and VEMP parameters was evaluated. The p1-n1 and n2-p2 waves were more frequently absent in MS than in control subjects [p1-n1 wave absent: MS, 25 (25 %) ears; control, 6 (10 %) ears; P ≤ 0.02] [n2-p2 wave absent: MS, 44 (44 %) ears; control, 7 (12 %) ears; P ≤ 0.001]. The mean p1-n1 amplitude was lower in MS than in control subjects (MS, 19.1 ± 7.2 μV; control, 23.3 ± 7.4 μV; P ≤ 0.002). A total of 24/50 (48 %) MS patients had VEMP abnormalities (absent responses and/or prolonged latencies). VEMP abnormalities were more frequent in patients with than without vestibular symptoms (P ≤ 0.02) and with brainstem functional system score (FSS) ≥ 1 than FSS = 0 (P ≤ 0.02). In patients with MS, absence of p1-n1 wave was more frequent in patients with than without vestibular symptoms [absence of p1-n1 wave: vestibular symptoms, 9 (45 %) ears; no vestibular symptoms, 16 (20 %) ears; P ≤ 0.03] and patients with Expanded Disability Status Scale (EDSS) score ≥ 5.5 [absence of p1-n1 wave: EDSS ≥ 5.5, 7 (70 %) ears; EDSS5.5, 18 (20 %) ears; P ≤ 0.001]. Abnormal VEMP may be noted in MS patients, especially those with vestibular symptoms and greater disability. The VEMP test may complement other studies for diagnosis and follow-up of patients with MS.

WOS:000393324400005 PubMed: 29392039 Objective: To investigate the outcomes of superficial musculoaponeurotic system (SMAS) flap and classic techniques in superficial parotidectomy in terms of Frey's syndrome (FS) and cosmetic satisfaction. Methods: In this study, a retrospective chart review of patients that underwent superficial parotidectomy was performed. These patients were divided into two subgroups: group 1 included patients in which the SMAS flap was harvested and group 2 comprised the remaining patients on whom classic superficial parotidectomy was performed. All the patients were evaluated clinically and with Minor's starch-iodine test for FS. For the evaluation of the cosmetic results, the patient's satisfaction was queried according to the incision scar and surgical field skin retraction/facial symmetry. Both groups were compared in terms of complications and numbness of surgical area. Results: Fifty-five patients (31 male and 24 female) with a mean age of 50.19 years were included in the study. Thirty-two patients were in group 1 and 23 in group 2. Thirteen patients (23.7%) described as having FS and six of them were in group 1, while seven were in group 2. Minor's starch-iodine test was positive in nine patients in group 1 (28.1%) and six patients in group 2 (26.1%) (p=1.000). With regard to cosmetic satisfaction, eight patients (25%) stated mild discomfort from the incision scar and two patients (6.3%) stated cosmetic dissatisfaction for facial asymmetry in group 1. In group 2 for the same factors the number of patients were 11 (47.8%) and 2 two (8.7%), respectively (p=0.027). There were no statistically significant differences in means of complication and numbness (p>0.05). Conclusion: According to our study results, there was no superiority between both the groups in terms of FS and incision scar satisfaction. We determined that there was a significant benefit of SMAS flap application in the prevention of volume loss and surgical area retraction.
