Functional outcomes and caloric response changes after endolymphatic sac decompression.

OBJECTIVE: To evaluate caloric response changes after endolymphatic sac decompression (ESD), together with hearing outcomes and the functional benefit of the operation. METHODS: A retrospective chart review of subjects who underwent endolymphatic sac decompression at a tertiary referral centre was performed. Data on audiological results, caloric testing, and functional level scale of the patients were analysed. RESULTS: Twenty-eight patients who met our criteria were eligible for enrolment in the study. The average follow-up after surgery was 25 months (range, 13-41). Postoperative pure-tone threshold averages and reduced vestibular response values (RVR) were not significantly altered by ESD; whereas, functional level scores improved significantly. CONCLUSION: Endolymphatic sac decompression is a surgical procedure that preserves hearing and vestibular function, and improves the daily functional level of patients with Ménière's disease. ESD can be preferred both in bilateral and unilateral disease because it does not alter vestibular function and preserves hearing.

Olfactory function assessment of migraine patients by using the Sniffin' sticks test: A clinical study.

OBJECTIVE: This as a cross-sectional controlled clinical study. We hypothesis that the olfactory functions in migraine patients may differ from the healthy controls. In this study, we evaluated the olfactory functions by using a Sniffin' Sticks test battery, which is a reliable and semi quantitative test to evaluate for olfactory dysfunction. METHODS: Patients above 18 years of age who had migraine received a definitive diagnosis of migraine from experienced headache specialists based on the criteria of The International Classification of Headache Disorders-3 were included. Odor threshold, discrimination, and identification parameters were assessed using the "Sniffin' Sticks" test. RESULTS: One-hundred and one migraine patients (age [mean ± SD], 36.9 ± 10.4 years; range, 18-60 years) and sixty healthy volunteers (age 34.5 ± 13.2 years, range 18-65 years) participated in our study. The median odor threshold score [percentiles 25th-75th] was 8.3 [6.5-9.8] for the migraine group during attack free period and 4.5[3.6-6.0] for the control group. It was found that the migraine group had a median odor discrimination score of 10.0 [10.0-13.0] and the control group 12.0 [11.0-13.0]. These differences were statistically significant (p < 0.001 and p = 0.032 respectively). The median odor discrimination and identification scores were statistically significant higher for the participants with higher educational level group than in those of lower educational group (p < 0.0001). The median odor discrimination and identification scores of those without allodynia (12.0 [10.0-14.0] and 13.0 [10.0-13.0] respectively) were higher than that of those with allodynia (11.0 [9.0-12.0] and 11.0 [10.0-13.0] respectively) (p = 0.037 and p = 0.034 respectively). CONCLUSIONS: We found that the odor thresholds, discrimination and identification scores of the migraine group demonstrate differences from those of the healthy group and in relation to allodynia.

Airway management during unusual tracheal stenosis: A clinical feasibility trial.

Objectives: Prolonged intubation is a known risk factor of LTS. LTS related to COVID-19 may result in a different phenotype: pronation affects the location of stenosis and COVID-19 pneumonia can decline lung mechanics. Therefore, airway management in these patients may carry unique challenges for both anesthesiologists and surgeons.This prospective observational feasibility trial aims to evaluate the use of a novel thin, cuffed, endotracheal tube (Tritube) in combination with flow-controlled ventilation (FCV) in the management of patients with COVID-19-related LTS undergoing laryngeal surgery. Methods: 20 patients suffering from COVID-19-related LTS, as diagnosed by CT, requiring endolaryngeal surgery, with or without CO2 laser, were included. Ultrathin endotracheal tube Tritube, together with FCV was used for airway management and ventilation. Feasibility, ventilation efficiency, and surgical exposure were evaluated. Results: Median duration of mechanical ventilation during their ICU stay was 17 days, (range, 7-27), and all patients had been pronated. In 18/20 patients, endoscopic diagnosis confirmed the initial CT diagnosis: posterior subglottic stenosis. Surgeons' satisfaction on the view was rated 9 out of 10 (range 7-10), where 0 was the worst view and 10 was the best view. Hemodynamic and respiratory variables were within the normal clinical range during the surgical procedure. One patient that had a SpO2 of 90% before induction of anesthesia, a temporal drop to 89%, caused meeting the predefined requirement of "respiratory complication." Conclusion: This study demonstrates the feasibility of using Tritube with FCV in patients with relatively unusual subglottic posterior location tracheal stenosis, undergoing laryngotracheal surgery. Tritube provides a good surgical field and FCV provides highly adequate ventilation especially in patients with compromised lung mechanics. Level of Evidence: IV, non-comparitive prospective clinical trial with 20 patients.

The effect of bony obliteration on quality of life after tympano-mastoidectomy surgery: A prospective observational controlled cohort study.

Objectives: The study's primary objective was to compare the quality of life (QoL) and external auditory canal (EAC) hygiene among patients who underwent bony mastoid obliteration or meatoplasty after canal wall down (CWD) mastoidectomy. Methods: A prospective, observational, controlled cohort study was conducted at our tertiary referral university hospital. Twenty-eight patients older than 16 years of age with chronic otitis media who underwent CWD mastoidectomy were included. Two cohorts were followed: CWD mastoidectomy followed by mastoid obliteration (Group 1, n = 14) and CWD mastoidectomy followed by meatoplasty (Group 2, n = 14). The main outcome measures of total COMBI score (postoperative 6-month QoL) and EAC hygiene were compared between the groups. Results: The average age of the patients was 36.14 (12. 22) years; 15 (53.6%) were female and 13 (46.4%) were male. There were no differences in demographic variables, preoperative findings, or COMQ-12 (preoperative QoL) scores between groups. The average COMBI score of Group 1 (49.0 [8.66]) was not significantly different from Group 2 (46.79 [7.76]) (p = .482). Poor EAC hygiene was observed in eight (57.1%) patients in Group 2 and three (21.4%) patients in Group 1 (p = .06). In Group 1, no resorption of graft material was observed in 10 (71.4%) patients, minor resorption was observed in three (21.4%) patients, and significant resorption was observed in one (7.1%) patient. There were no significant differences in audiological findings between groups (p > .05). Conclusion: There were no significant differences regarding short-term postoperative QoL, EAC hygiene, or hearing outcomes between patients who underwent bony mastoid obliteration or meatoplasty after CWD mastoidectomy. Level of Evidence: 1b (individual prospective cohort study).

The Effects of Neuromuscular Electrical Stimulation on Swallowing Functions in Post-stroke Dysphagia: A Randomized Controlled Trial.

The study aimed to evaluate the effects of traditional dysphagia therapy (TDT) and neuromuscular electrical stimulation (NMES) combined with TDT on functionality of oral intake, dysphagia symptom severity, swallowing- and voice-related quality of life, leakage, penetration-aspiration, and residue levels in patients with post-stroke dysphagia (PSD). Thirty-four patients with PSD were included in our prospective, randomized, controlled, and single-blind study. The patients were divided into two groups: (1) TDT only (control group, n = 17) and (2) TDT with NMES (experimental group, n = 17). TDT was applied to both groups for three consecutive weeks, 5 days a week, 45 min a day. Sensory NMES was applied to the experimental group for 45 min per session. Patients were evaluated by the functional oral intake scale (FOIS), the eating assessment tool (EAT-10), the swallowing quality of life questionnaire (SWAL-QOL), and the voice-related quality of life questionnaire (VRQOL) at baseline, immediately post-intervention, and at the 3rd month post-intervention. Fiberoptic endoscopic evaluation of swallowing (FEES) with liquid and semi-solid food was performed pre- and post-intervention. A significant post-intervention improvement was observed on all scales in both groups, and these improvements were maintained 3 months post-intervention. Leakage and penetration-aspiration levels with semi-solid food declined only in the experimental group. In conclusion, TDT is a non-invasive and inexpensive method that leads to improvement in many swallowing-related features in stroke patients; however, NMES as an adjunct therapy is costly but can provide additional benefits for improving features, such as penetration-aspiration and residue levels.

Comparison of Stroke Volume Variation-based goal-directed Therapy Versus Standard Fluid Therapy in Patients Undergoing Head and Neck Surgery: A Randomized Controlled Study

Background: Perioperative fluid therapy is used to avoid dehydration and hypovolemia. Optimum perioperative fluid administration may improve postoperative outcomes after major surgery, and the optimal strategy remains controversial and uncertain. Aims: The primary outcome was the total amount of intraoperative fluids given between perioperative goal-directed fluid therapy (GDFT) guided by a hemodynamic monitoring system and standard fluid therapy based on "mean arterial pressure-diuresis" data in patients undergoing head and neck surgery. The secondary outcomes were the hemodynamics and laboratory variables, postoperative complications, length of mechanical ventilation, intensive care unit and hospital stay. Study Design: A randomized controlled study. Methods: Sixty patients were scheduled and randomized into two groups of 30 patients each: in the study group, an arterial pressure catheter was inserted and connected to the FloTrac system, whereas in the control group, an arterial pressure catheter was inserted and integrated into the hemodynamic monitoring system with a special transducer. The control group had fluids administered at the discretion of the anesthesiologist according to the mean arterial pressure >65 mmHg and diuresis >0.5 ml/kg/h. In the study group, fluid management was administered to achieve a target value of ≤13% through the stroke volume variation. Results: The total amounts of fluid in the intraoperative period were different between the groups, with the study group receiving significantly more fluids (P = 0.0455). The length of hospital stay was significantly longer in the study group than in the control group (P = 0.012), but prolonged oxygen demand was significantly more frequent in the control group than in the study group (P = 0.017). No difference was found in hemodynamics, lactate kinetics, and vasoactive agent requirements. Conclusion: The standard fluid therapy guided by conventional circulatory parameters appears sufficient for patients with low-tomoderate risk during head and neck surgery.

Comparison of crushed cartilage used and not used as camouflage grafts in patients who had undergone septorhinoplasty.

OBJECTIVE: Septorhinoplasty is the most frequently performed aesthetic operation. Many techniques are used in septorhinoplasty, and these techniques can affect patient satisfaction, which is one of the most important parameters showing success in surgery. In this study, we aimed to compare the postoperative satisfaction of patients with and without crushed cartilage onlay grafts. METHODS: Patients who underwent septorhinoplasty between 2017 and 2019 were included in the study. A rhinoplasty outcomes evaluation (ROE) questionnaire and a visual analog scale (VAS) were completed before and after surgery. Pre- and postoperative values were compared. The patients were classified into two groups as patients with or without crushed cartilage grafts, and the results were compared. RESULTS: A total of patients were included in our study, 54 of which were female, and 39 were male. Results showed that post-operative ROE and VAS scores were statistically significantly improved (p < 0.05). In the group with crushed cartilage, the 12th month ROE and VAS scores were lower than the group without crushed cartilage (p < 0.05). CONCLUSION: In the group with crushed cartilage, the satisfaction levels in the 12th month were lower than those of the patients without crushed cartilage.

Evaluation of the factors affecting the necessity for revision surgery in choanal atresia.

OBJECTIVE: This study aims to compare the effects of different surgical techniques for congenital choanal atresia (CCA), and particular emphasis is given to the analysis of the factors affecting the surgical outcome. The necessity for revision surgery and surgical outcomes were retrospectively investigated in patients undergoing revision surgery according to a recently proposed classification system. MATERIAL AND METHOD: A retrospective study was conducted on patients operated for CCA between January 2007 and December 2018 at a university hospital. Data in the medical records, including patient age when the initial surgery was performed, gender, additional anomalies and medical conditions, the duration of gestation, side and type of atresia, type of surgery and need for revision surgery were reviewed. RESULTS: Forty-five patients treated for CCA in our university hospital were screened. The mean follow-up duration was 82.16 months. Revision surgery was required in 9 of 26 cases, which are included in the study (34.6%). Fourteen patients presented with bilateral CCA, while 12 were unilateral cases. Sixteen patients (61.5%) had comorbid medical conditions. While the removal of vomer and mucoperiosteal flap use affects successful surgical repair, no differences were observed in choanal atresia type, laterality, use of stent and the presence of additional medical conditions. CONCLUSION: The most important factors affecting surgical success for CCA are the removal of the vomer and closure of all bare bone tissues using a mucoperiosteal flap. Use of stents provides no additional benefit, apart from preventing synechiae formation.

Bilateral Ethmoidal Mucocele Causing Proptosis in a Child.

OBJECTIVES: Paranasal sinus mucocele is a benign cystic lesion, lined with respiratory epithelium and filled with mucoid secretions, which is generally seen in the ethmoid or frontal sinuses. Inflammation, trauma, fibrosis, neoplasm, and previous surgery play a role in etiology. Treatment of this condition requires marsupialization and drainage. Endoscopic surgery is the gold standard procedure. METHODS: A 2-year-old boy was referred to our clinic with a diagnosis of bilateral ethmoid mucocele causing proptosis in the right eye. General clinical examinations and routine blood analysis revealed normal health condition of the patient and comorbidities such as cystic fibrosis (CF) and/or ciliary dysfunction were excluded. The patient was operated with an endoscopic endonasal approach. RESULTS: As far as we know, our article reports the first case of bilateral ethmoidal sinus mucocele with no underlying comorbidity, such as cystic fibrosis or ciliary dyskinesia. CONCLUSIONS: Children are rarely affected by mucocele and if present at early age, there is usually an underlying cause. In pediatric patients with signs and symptoms suggestive of a mucocele, it is important to rule out other benign and malignant paranasal sinus pathologies. Marsupialization and drainage via endoscopic endonasal approach is the preferred treatment modality.

Olfactory dysfunction in patients with cluster headache.

OBJECTIVE: Cluster headache (CH) is a primary headache characterized by strictly unilateral, short-lasting severe headache attacks accompanied by at least one ipsilateral autonomic symptom. Our study aimed to determine whether CH patients had olfactory dysfunction and to correlate it with clinical characteristics. MATERIALS AND METHODS: Twenty patients and 57 healthy volunteers were included in the study. All participants were examined in the otorhinolaryngology outpatient clinics to exclude other clinical problems causing olfactory dysfunction. The Sniffin' Sticks test was performed, and threshold (T), discrimination (D), identification (I) scores, and TDI global olfactory score were evaluated. RESULTS: The CH patients had significantly lower threshold scores than healthy controls (6.9 ± 1.70 vs. 7.8 ± 1.08, p = 0.007). The mean threshold scores of CH patients during in-bout (n = 9) were significantly lower than CH patients during out-of-bout (n = 11) in subgroup analysis (5.9 ± 1.16 vs. 7.6 ± 1.76, p = 0.038). CH patients with left-sided headache had significantly lower discrimination scores compared to CH patients with right-sided headache (12.8 ± 1.24 vs. 14.4 ± 1.51, p = 0.03). CONCLUSION: There is marked impairment in olfactory function in CH patients compared to healthy controls.

Squamous Cell Carcinoma Mimicking Neck Paraganglioma on 68Ga-DOTATATE PET/CT.

ABSTRACT: Somatostatin receptor (SSTR) imaging with 68Ga-labeled somatostatin analogs has been used for many tumors with high SSTR expression. Increased uptake mostly depends on the SSTR status of tumors; however, false-positive uptake can be demonstrated in benign diseases or other malignancies because of the increased SSTR expression. We present a case of a 50-year-old man with increased SSTR activity on cervical lesion located in internal jugular chain in 68Ga-DOTATATE PET/CT, which was performed for suspicion of paraganglioma. Biopsy revealed lymph node metastasis of squamous cell carcinoma other than paraganglioma. 18F-FDG PET/CT showed primary malignancy on larynx and lymph node metastasis, which were correlated surgically.

Assessment of the Olfactory Function in Patients With Idiopathic Intracranial Hypertension Using the Sniffin' Sticks Test: A Case-Control Study.

OBJECTIVE: Despite the lack of recognition in clinical practice, there is increasing evidence that patients with idiopathic intracranial hypertension may suffer from hyposmia. The current case-control study aims to evaluate olfactory dysfunction in a large series of patients with idiopathic intracranial hypertension. METHODS: All subjects, 44 idiopathic intracranial hypertension patients and 57 healthy controls, underwent olfactory function assessment using standardized "Sniffin' Sticks" test at a tertiary referral center of a university hospital. Threshold, discrimination, identification, and total threshold-discrimination-identification scores have been determined and analyzed statistically. RESULTS: Idiopathic intracranial hypertension patients had significantly lower threshold (6.5 [3.69] vs 8 [1.88], P < .001, 95% CI [-2.250, -0.750]) and threshold-discrimination-identification scores (29.75 [5.56] vs 32.5 [5.25], P = .003, 95% CI [-4.250, -0.750]). Twenty-five patients (57%) were diagnosed with hyposmia. Test scores of patients with active idiopathic intracranial hypertension (n = 18) were not statistically different from patients with inactive disease (n = 26), except for discrimination score (14 [2.50] vs 11 [2.25], P = .005, 95% CI [-3.000, -1.000]). Although idiopathic intracranial hypertension patients with a cerebrospinal fluid opening pressure of ≥330 mmH2 O had lower test scores, the difference was significant only for total threshold-discrimination-identification scores (28.5 [5.50] vs 30.5 [4.38], P = .044, 95% CI [0.750, 5.500]). Multiple regression analysis revealed that test scores were related to disease activity, cerebrospinal fluid opening pressure, papilledema, headache, and medication. CONCLUSION: Our clinical study revealed significant olfactory dysfunction in patients with idiopathic intracranial hypertension compared with healthy controls. Future research should employ larger samples to search for usability of olfactory testing in clinical management of patients with idiopathic intracranial hypertension.

Olfactory dysfunction and quality of life in patients with transfusion-dependent thalassemia.

Transfusion-dependent thalassemia (TDT) is a group of thalassemia syndromes that require regular blood transfusions for survival. It is unknown whether the sense of smell of patients with TDT is affected, and if so, whether smell loss has an adverse effect on quality of life (QOL). Olfactory thresholds were measured using Snap & Sniff® wands. QOL was assessed via the Short Form-36 (SF-36) questionnaire. Forty-two TDT patients from the Thalassemia Center in Istanbul Medical Faculty were tested (mean age 26.6 years), along with 42 healthy controls (mean age 28.0 years). Mean olfactory sensitivity was lower in the TDT patients than the controls (p < 0.0001). TDT was associated with lower mean QOL scores on the domains of physical function (p < 0.0001), physical role limitation (p = 0.011), and general health (p < 0.0001). Within the TDT group, significant correlations were present between the threshold scores and physical function, physical role limitation, emotional role limitation, and general health. Patients with TDT are less sensitive to odors than healthy controls and the lower olfactory test scores are related to lower quality of life, suggesting that decreased smell function is an additional complication of this disease.

Transnasal Prelacrimal Recess Approach for Recurrent Antrachoanal Polyp.

PURPOSE: To assess the effectiveness and usefulness of transnasal prelacrimal recess approach (TPRA) in patients with recurrent antrochoanal polyps. METHODS: Twelve patients with antrochoanal polyp recurrence underwent surgery with a transnasal endoscopic prelacrimal recess approach. Success for visualization of the origin of the polyps, surgical complications, and recurrence was evaluated. RESULTS: Transnasal prelacrimal recess approach was successful in 83% of the patients (10/12); polyps that originated from a posterior location (2 patients) were excised using the middle meatal approach. Nasolacrimal duct injury occurred in 2 patients but neither had epiphora postoperatively. Three patients (3/12; 25%) had synechia formation between the lateral nasal wall and septum just superior to the inferior turbinate. One of the 3 patients (1/12; 8.3%) with synechia was symptomatic and required surgical treatment under local anesthesia. During a mean follow-up period of 14.2 months (range, 8-21 months) no recurrence had developed. CONCLUSION: In experienced hands, TPRA is a novel, reliable, and useful method for the treatment of recurrent antrochoanal polyps. It ensures good exploration of the maxillary antrum and easy access to the polyp origin on the maxillary wall without the need of additional approaches.
