RESUMO

PURPOSE: Several diagnostic modalities are used to detect CSF leaks. Intraoperative use of intrathecal fluorescein can help to detect and localize a CSF leak simultaneously. However, it is not FDA approved, the application is invasive and has serious complications. Topical fluorescein is reported to be a safe and sensitive alternative to ITF. In this study, we aimed to evaluate the effectiveness of topical fluorescein in CSF leak closure. METHODS: This retrospective study includes 27 consecutive patients (19 women, 8 men) who underwent endoscopic endonasal CSF leak closure using topical fluorescein, between 2011 and 2017. RESULTS: In two patients, radiologic studies false positively locate the defect. ß2 transferrin and topical fluorescein tests were positive in these patients. Both cases needed a second operation. CONCLUSION: If radiologic studies fail to locate the defect properly, topical fluorescein only confirms the CSF leak, but the defect cannot be located anatomically intraoperatively.

RESUMO

OBJECTIVE: The aim of this study was to share our clinical experience with the neurovascular myofasiocutan infrahyoid flap (NMIHF), which was used for the reconstruction of the defects after oral cavity cancer surgery. METHODS: Records of five patients who were diagnosed with oral cavity cancer and underwent tumor resection, neck dissection, and defect reconstruction with NMIHF between 2012 and 2017 were analyzed retrospectively. RESULTS: The infrahyoid flap was used in five patients: four males and one female. The mean age of patients was 61.8 years. Four patients underwent tumor resection and bilateral level I-III neck dissection, whereas one patient underwent tumor resection and unilateral level I-III neck dissection. NMIHF was used for the reconstruction of the defects during the same procedure in all the patients. Mean post-operative follow-up was 30.6 months. Partial skin necrosis was observed in two patients, but none of the patients showed total necrosis of the flap. Postoperatively, oral intake was initiated after an average of 12 days in all patients. For two patients who required post-operative radiotherapy (RT), the treatment was started after an average of 50 days. CONCLUSION: NMIHF does not prolong operation time and does not cause additional scar in the neck, and the defect in the donor field can be closed without the use of a graft or flap. This is considered to be a reliable and successful alternative to free flaps for the reconstruction of oral cavity defects.

RESUMO

OBJECTIVES: To present the outcomes of our case series of head and neck necrotizing fasciitis (HNNF) in which vacuum-assisted closure (VAC) is used in most of the cases in the treatment. METHODS: Case series in a tertiary referral center. RESULTS: Eleven patients were treated for HNNF between January 2008 and January 2017. Patients were two females and nine males, the mean age was 57.1. Oral cavity and tracheotomy/tracheostomy sites were the main aetiological foci of the infection. Three patients were treated with aggressive debridements and conventional dressing, whereas eight patients were treated with incision and exploration followed by limited skin excisions and VAC dressing. The mean number of surgical debridements was 2.3. The mean length of hospital stay was 41.8 days. Complications were observed in all patients except one. The mortality rate of HNNF in our series was 18%. The cause of death was severe sepsis and multi-organ failure in one case and mediastinitis followed by respiratory distress syndrome in the other case. CONCLUSION: HNNF is still a mortal disease and surgical debridements are crucial. The current study is the only case series in the literature in which VAC treatment was used in consecutive cases of HNNF. VAC treatment can play a major role in the post-operative care of HNNF patients. It reduces the amount of excised skin during debridements and stimulates wound healing. VAC treatment may be included in the treatment protocol of HNNF alongside surgical debridements and medical therapy.

RESUMO

Background The necessity of silicone stenting in endoscopic dacryocystorhinostomy (DCR) procedures is a controversial subject in the literature. Objective The purpose of the present study is to assess the long-term anatomical and functional outcomes of endoscopic-powered DCR (EP-DCR) without stenting or mucosal flaps. Methods One hundred twenty EP-DCR procedures were performed in 107 patients. Anatomical success was defined as a patent ostium on irrigation and functional success as free flow of dye from the ostium and resolution of epiphora. Results The mean follow-up was 46.5 months (range: 24-87). Of the 120 procedures, 13 were bilateral and 94 were unilateral. Anatomical and functional success rates of 92.5% were obtained. Conclusion EP-DCR without stenting is a safe and economic technique that provides satisfactory long-term results and could be considered as the treatment of choice for patients with postsaccal nasolacrimal duct obstruction.

RESUMO

BACKGROUND: The accuracy of fine-needle aspiration biopsy (FNAB) is controversial in parotid tumors. We aimed to compare FNAB results with the final histopathological diagnosis and to apply the "Sal classification" to our data and discuss its results and its place in parotid gland cytology. METHODS: The FNAB cytological findings and final histological diagnosis were assessed retrospectively in 2 different scenarios based on the distribution of nondefinitive cytology, and we applied the Sal classification and determined malignancy rate, sensitivity, and specificity for each category. RESULTS: In 2 different scenarios FNAB sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were found to be 81%, 87%, 54.7%, and 96.1%; and 65.3%, 100%, 100%, and 96.1%, respectively. The malignancy rates and sensitivity and specificity were also calculated and discussed for each Sal category. CONCLUSION: We believe that the Sal classification has a great potential to be a useful tool in classification of parotid gland cytology.

RESUMO

Objective To determine the predictive value of nasal endoscopic findings and symptoms in the diagnosis of granulomatosis with polyangiitis (GPA). Study Design A cross-sectional study. Setting A tertiary university hospital. Subjects and Methods A total of 116 adults were enrolled in the study: 19 patients with GPA, 29 patients with other rheumatic diseases, and 68 healthy volunteers. All patients were examined with a flexible endoscope, and nasal endoscopic images were recorded and evaluated blindly. The medical history of each patient was taken by a physician blinded to the patient's diagnosis. Results Univariate analysis indicated a statistically significant difference in rhinorrhea ( P = .002), postnasal drip ( P = .015), epistaxis ( P < .001), and saddle nose ( P = .017). However, binary logistic regression analysis demonstrated that only history of epistaxis ( P = .012; odds ratio, 5.6) was statistically significant in predicting GPA. Univariate analysis showed a statistically significant difference in nasal secretion ( P = .028), nasal septal perforation ( P < .017), nasal crusting ( P < .001), nasal adhesion ( P < .001), nasal granuloma ( P = .017), and hemorrhagic fragile nasal mucosa ( P < .001). A binary logistic regression analysis demonstrated that only hemorrhagic fragile nasal mucosa ( P < .001; odds ratio, 52.9) was a statistically significant predictor of GPA. Conclusions Given the results of this study, we believe that hemorrhagic fragile nasal mucosa and history of recurrent epistaxis may put patients at risk for GPA and should be investigated accordingly.

RESUMO

The objective of this study was to determine the incidence of thyroid gland invasion in laryngeal and hypopharyngeal squamous cell carcinoma; and the association between clinicopathological parameters and thyroid gland invasion. Medical records of 75 patients with laryngeal and hypopharyngeal squamous cell carcinoma who underwent total laryngectomy with thyroidectomy were reviewed, retrospectively. Preoperative computed tomography scans, clinical and operative findings, and histopathological data of the specimens were evaluated. There were 73 male and two female patients with an age range of 41-88 years (mean 60.4 years). Hemithyroidectomy was performed in 62 (82.7 %) and total thyroidectomy was performed in 13 patients (17.3 %). Four patients had histopathologically proven thyroid gland invasion (5.3 %). In three patients, thyroid gland involvement was by means of direct invasion. Thyroid gland invasion was significantly correlated with thyroid cartilage invasion. Therefore, prophylactic thyroidectomy should not be a part of the treatment policy for these tumors.

RESUMO

The aim of our study was to present our retrospective experience in the single-stage surgical reconstruction of 21 tracheal stenosis (TS) patients during the last 17 years, considering the characteristics of the treated stenosis, surgical procedures performed, and postoperative outcomes and complications. All demographic and clinical data were collected retrospectively. Chest and neck computed tomography (CT) scans were performed to assess the stenosis, including length, location, and glottic involvement. The stenotic area was evaluated endoscopically according to an adapted Myer and Cotton grading scale. The aetiology of the (TS) was intubation related in 18 patients and idiopathic in three patients. The duration of intubation was 13.00 ±â€Š6.83 days (range, 1 hour to 27 days). According to the Myers-Cotton classification, mean stage of stenosis for the study group was 3.33 ±â€Š0.66 (range, 2-4). Mean length of the stenosis was 2.05 ±â€Š0.80 (range, 1-3.5) cm. The mean number of stenotic segment involved was 3.67 ±â€Š1.24 (range, 2-6). Mean follow-up for the study group, excluding two patients who died in the postoperative period, was 57 (range, 12-326) months. Of the 19 patients who survived, postoperative decannulation was achieved in 16 patients (76.19%), and decannulation was not achieved in 3 patients (14.29%) who are still on a T-tube. Of the 16 patients who are decannulated successfully, additional procedures were applied in 9 patients. Segmental resection with primary anastomosis is an effective method and can be used as the first option in selected patients of (TS).

RESUMO

CONCLUSION: Delivery of a carbon dioxide laser is an effective method and can be used in selected cases of tracheal stenosis. OBJECTIVES: To present retrospective experience in tracheal stenosis of 16 patients treated by bronchoscopic delivery of carbon dioxide laser, considering the characteristics of the treated stenosis, surgical procedures performed, and post-operative outcomes and complications. METHODS: All demographic and clinical data were collected retrospectively. Chest and neck computed tomography scans were performed to assess the stenosis, including length, location, and glottic involvement. The stenotic area was evaluated endoscopically according to an adapted Meyer and Cotton grading scale. RESULTS: The aetiology of the tracheal stenosis was intubation-related in 14 cases, and idiopathic in two cases. The duration of intubation ranged between 1 hour to 26 days. According to the Myers-Cotton classification, mean stage of stenosis for the study group was 3.3 ± 0.5. Mean length of the stenosis was 23.75 ± 6.95 (range = 15-40) mm. Mean follow-up for the study group was 23.81 ± 7.11 (range = 12-38) months. Postoperative decannulation was achieved in 13 patients (81.3%), and decannulation was not achieved in three patients (18.7%).

RESUMO

BACKGROUND: There is no consensus as to whether allergic rhinitis (AR) is a cause of adenoid hypertrophy (AH). This study evaluated the role of allergy in AH, and it explored the role of nasal endoscopy and the history of diagnosing AR in children empirically. MATERIALS AND METHODS: This study enrolled 155 children consecutively in Izmir Behcet Uz Children`s Hospital between January and September 2013. RESULTS: Of the patients, 101 (65.2%) had a positive skin prick test. Multiple allergen sensitivity was identified in 76 (75.2%) of these patients. The history items of itching and sneezing had predictive value for empirically diagnosing AR in children. Of the nasal examination findings, only the nasal secretion characteristics had significant predictive value. AH and AR had a significant negative correlation. CONCLUSION: In this study, AH and AR were inversely related. The characteristics of the nasal secretions, itching, sneezing, were predictors of AR in children.

RESUMO

INTRODUCTION: Posterior nasal neurectomy is an effective way of treating recalcitrant rhinitis. The aim of this study is to describe the anatomic relationship between the posterior inferior nasal nerve (PINN) and the structures that might be important for posterior nasal neurectomy. MATERIALS AND METHODS: An anatomic study was conducted in a university hospital dissection laboratory with 15 formalin-fixed, sagittally cut adult cadaver heads. The distance between PINN and (1) nasal sill, (2) maxillary sinus ostium, (3) posterior fontanel, (4) torus tubarius, and (5) crista ethmoidalis was measured and the location of PINN with respect to the sphenopalatine artery was assessed to define the exact location of PINN. RESULTS: The mean distance between PINN and nasal sill (56.4 mm), maxillary sinus ostium (27 mm), posterior fontanel (12.5 mm), torus tubarius (13 mm), and crista ethmoidalis (8 mm) was determined. PINN was found consistently posterior to the sphenopalatine artery where the inferior turbinate attaches to the lateral nasal wall. CONCLUSION: Instead of finding PINN around the sphenopalatine foramen, PINN can be located more easily posterior to the sphenopalatine artery where the inferior turbinate attaches to the lateral nasal wall without cauterizing the sphenopalatine artery.

RESUMO

CONCLUSION: Echo-planar diffusion-weighted magnetic resonance imaging (DW MRI) is more reliable than high-resolution computed tomography (HRCT) in predicting the presence and localization of cholesteatoma before tympanomastoid surgery. OBJECTIVES: To evaluate the diagnostic accuracy of HRCT and echo-planar DW MRI in the detection and localization of cholesteatoma. METHODS: Fifty-nine patients were prospectively included in this study. Patients with suspected primary cholesteatoma were evaluated by HRCT and echo-planar DW MRI before tympanomastoid surgery. Radiological findings were correlated with intraoperative findings. RESULTS: HRCT and echo-planar DW MRI accurately predicted the presence or absence of cholesteatoma in 40/59 (67.8%) and 52/59 (88.1%) patients, respectively. The sensitivity, specificity, and positive and negative predictive values of HRCT were 68.97%, 66.67%, 66.67%, and 68.97%, respectively. However, sensitivity, specificity, and positive and negative predictive values of echo-planar DW MRI were 85.71%, 90.32%, 88.89%, and 87.50%, respectively.

RESUMO

This paper describes a tension pneumocephalus without cerebrospinal fluid leak, a rare complication of septoplasty. We present a case of tension pneumocephalus without cerebrospinal fluid leak 1 month after a septoplasty operation. Although endoscopic sinus surgery can be utilized for repair of the defect, intracranially displaced ethmoid bone fragment makes an open approach more feasible. His postoperative course was uneventful and postoperative CT scan revealed no signs of pneumocephalus. Absence of cerebrospinal fluid leak made this case unique in presentation and caused a delay in diagnosis. Severe headache after septoplasty should alert the surgeon to investigate possible intracranial complications.

RESUMO

OBJECTIVE: To demonstrate if cochleopathy in patients with type 2 diabetes with normal audiometric hearing threshold can be detected with otoacoustic emissions or medial olivocochlear (MOC) reflex measurements. STUDY DESIGN: Cross-sectional study. SETTING: Tertiary university teaching hospital. METHODS: The study involved 40 type 2 diabetic patients and 24 healthy volunteers. All participants who showed normal otoscopic findings, hearing thresholds, and acoustic admittance were included. Cochlear activity of participants was evaluated by means of distortion product otoacoustic emissions (DPOAEs) and transient otoacoustic emissions (TOAEs). The MOC reflex was evoked with contralateral acoustic stimulation and recorded with DPOAEs and TOAEs. RESULT: A comparison of DPOAE and TOAE levels with a t test between patient and control groups revealed no significant difference (P > .05). A comparison of the MOC reflex response between the 2 groups also revealed no statistically significant difference (P > .05). CONCLUSION: Although decreased OAE amplitude levels were found in diabetic patients, there was no statistically significant difference in OAEs and MOC reflex. Additional studies are needed to evaluate the role of OAEs and MOC reflex in normal-hearing patients with diabetes.

RESUMO

We have planned to demonstrate histopathologic effects of mid- or long-term oral use of desloratadine and cetirizine HCl molecules on middle ear mucosa of rats. Thirty-six rats were randomized equally into six groups. Desloratadine groups received once daily doses of 1 mg/ml desloratadine for 30 (D30 Group) or 60 (D60 Group) days. The Cetirizine study groups were given once daily doses of 1 mg/ml cetirizine for 30 (S30 Group) or 60 (S60 Group) days. Control groups were given 2 cc physiologic saline using orogastric gavage method through a 12 G gavage catheter for 30 (K30 Group) or 60 (K60) days. At the end of 30 days, D30, S30 and K30 Groups were sacrificed. Tissue samples harvested from groups were evaluated between 1 and 4 Grades for histological characteristics of middle ear canal, eardrum, middle ear epithelium and connective tissue, edema, vascular congestion and inflammatory cells. In the control group no pathological finding was encountered in rats sacrificed on 30 and 60 days. No statistical difference was observed when groups were compared on external ear epithelial tissue, external ear sebaceous gland, middle ear inflammation, and middle ear capillary dilatation both on 30 and 60 days. Tympanic membrane collagen was more evident in D30 and D60 groups when compared with C30 and C60 groups. Comparison of histopathological grading results between 30 and 60 days revealed no significant changes. In conclusion, oral intake of cetirizine and desloratadine preparations has effects of tympanic membrane collagen, degrees of edema and vascular congestion being more prominent with desloratadine molecule.

RESUMO

The objective of the study was to determine the inter-rater variability in assessment of laryngeal findings and whether diagnosing laryngopharyngeal reflux based on the laryngeal findings and history alone without considering allergic rhinitis leads to the overdiagnosis and overtreatment of laryngopharyngeal reflux. Patients with positive and negative skin prick tests were recruited from an allergy clinic in a tertiary teaching university hospital. All subjects completed the Reflux Symptom Index (RSI) and underwent laryngeal examinations by three physicians blinded to the skin prick test results and the Reflux Finding Score (RFS) was determined. RFS >7 or RSI >13 was considered reflux positive. Fleiss' kappa (κ) was used to measure inter-rater agreement. The inter-rater agreement was low for pseudosulcus vocalis (κ = 0.078), ventricular obliteration (κ = 0.206), diffuse laryngeal edema (κ = 0.204), and posterior laryngeal hypertrophy (κ = 0.27), intermediate for laryngeal erythema/hyperemia (κ = 0.42) and vocal fold edema (κ = 0.42), and high for thick endolaryngeal mucus (κ = 0.61). Although the frequency of allergy was high, there was no significant difference between allergy-positive and laryngopharyngeal reflux-positive patients. On logistic regression analysis, thick endolaryngeal mucus was a significant predictor of allergy (p = 0.012, odds ratio 0.264, 95 % confidence interval 0.093-0.74). The laryngeal examination for reflux is subject to marked inter-rater variability and allergic laryngitis was not misdiagnosed as laryngopharyngeal reflux. The presence of thick endolaryngeal mucus should alert physicians to the possibility of allergic rhinitis/laryngitis.

RESUMO

Endoscopic sinus surgery is a widely used technique in otolaryngologic practice. To avoid complications, the locations of important anatomical structures, such as the anterior ethmoid artery (AEA), should be determined preoperatively. We want to evaluate the effect of ethmoid cavity pneumatization on the location of the AEA and to determine consistent landmark(s) for locating the AEA. 524 consecutive patients undergoing sinus CT scans between February and October 2012 were reviewed retrospectively. After the exclusion criteria were applied, 150 CT scans (300 sides) were selected for the study. A statistically significant positive correlation was found between ethmoid pneumatization and the distance of the AEA to the attachment of the inferior turbinate to the lateral nasal wall (Spearman's rho = 0.305; p < 0.001). Likewise, a statistically significant positive correlation was found between ethmoid pneumatization and the distance between the AEA and the frontonasal junction (Spearman's rho = 0.219; p < 0.001). We found that the artery was located mostly between the second and third lamellae [n 211 (71 %) cases]. There was no statistically significant correlation between ethmoid pneumatization and AEA location in terms of the lamellae. Increased ethmoid volume increases the distance of the AEA from the frontonasal junction and the lateral attachment of the inferior turbinate. However, increased pneumatization of the ethmoid cavity did not affect AEA localization in terms of the lamellae. Based on our findings, we suggest that using the lamellae to locate the AEA is reliable.

RESUMO

Laryngeal paragangliomas are rare neoplasms that originate in the neural crest cells of the laryngeal paraganglia. Although the vast majority of these tumors are benign, they exhibit different types of biologic behavior that require different treatment modalities. Therefore, differentiation among these tumors is extremely important. We report a rare case of laryngeal paraganglioma that presented as a transglottic lesion in a 68-year-old man. The atypical location of the tumor led to difficulties in diagnosis and management. To the best of our knowledge, this is only the third such case to be reported in the English-language literature.

RESUMO

HYPOTHESIS: To evaluate the effects of hyperandrogenism on otoacoustic emission levels and the medial olivocochlear reflex in adult female subjects. BACKGROUND: Women have a hearing advantage over men. Otoacoustic emission levels tend to be higher in female subjects, in both newborns and adults. This discrepancy has been presumed to result from prenatal androgen exposure in male subjects. METHODS: The study involved 37 polycystic ovary syndrome patients who were referred from the endocrinology department and 26 healthy volunteers. All participants who showed normal otoscopic findings, hearing thresholds, and acoustic admittance were included. All polycystic ovary syndrome patients showed biochemical signs of hyperandrogenism. Cochlear activity of participants was evaluated by means of distortion product otoacoustic emissions and transient otoacoustic emissions. The medial olivocochlear reflex was evoked with contralateral acoustic stimulation and recorded with distortion product otoacoustic emissions and transient otoacoustic emissions. RESULTS: Neither distortion products nor transient otoacoustic emission levels showed a statistically significant difference between the right and left ears (p > 0.05). Comparisons of distortion products and transient otoacoustic emission levels between the patient and control groups showed no statistically significant difference (p > 0.05). Comparison of the medial olivocochlear reflex response between the 2 groups also revealed no statistically significant difference (p > 0.05). CONCLUSION: Hyperandrogenism did not seem to influence otoacoustic emission levels or the medial olivocochlear reflex response in adult female subjects.

RESUMO

The objective of this study is to establish the role of risk factors in the etiology of pharyngocutaneous fistula formation after total laryngectomy. A retrospective study was performed for patient, disease and treatment-related factors, and also factors related to pathology specimen. Logistic regression analysis revealed that fistula development ratio was 4.955 times higher in patients with fistula than in the control group when the preoperative hemoglobin value was below 12.2 g/dL, 3.653 times higher when the postoperative hemoglobin value was below 12.2 g/dL, 3.471 times higher in the presence of an accompanying systemic disease, 3.23 times higher when the postoperative albumin level was below 3.5 g/dL, 3.1 times higher when ipsilateral lymph node was positive, 2.05 times higher when erythrocyte suspension is used as transfusion material, and 1.048 times higher when contralateral lymph node was positive. Proper concomitant systemic disease control, maintenance of hematologic values in the pre- and postoperative periods, provision of adequate nutrition, preference of erythrocyte suspensions for transfusion are the key points for the prevention of pharyngocutaneous fistula development. Preoperative detection of positive cervical lymph nodes should alert the physician about the potential development of fistula.
