Factors Affecting Success Rates in Endoscopic Repair of CSF Rhinorrhea.

Objectives: Our aim in this study is to assess the effect of factors such as age, etiology, defect size, application of lumbar drainage and surgical technique on Cerebrospinal Fluid (CSF) fistula repair success rates. Methods: The Electronic Medical Records (EMR) system of our clinic was retrospectively reviewed for cases that were operated between 2006 and 2020 for CSF fistula originating from anterior skull base with endoscopic transnasal technique. A total of 35 patients were included in the study. Patients were grouped according to the number of layers used in repair (two, three or four-layered reconstruction) and defect size (smaller than 5 mm, 5 to 10 mm and larger than 10mm), etiology, location of the defect and application of lumbar drainage as LD (+) and LD (-). Complications and CSF leak recurrence were compared between groups. Results: Recurrence rates in patients who had 2 layered reconstructions were significantly higher compared to patients who had 3 or 4 layered reconstructions (p=0.049). The recurrence rate in LD (+) group (41.7%) was significantly lower compared to LD (-) group (4.3%) (p=0.012). There were no significant difference in recurrence rates between groups in terms of age, defect size, defect location and etiology. Conclusion: In endoscopic transnasal repair of anterior skull base-derived bos fistulas, planning the reconstruction at least 3 times and applying lumbar CSF drainage increases the success rates.

Effects of submucoperichondrial application of platelet-rich plasma on nasal mucosal healing after septoplasty.

OBJECTIVE(S): Our aim is to investigate the effects of the submucoperichondrial application of Platelet Rich Plasma (PRP) on nasal mucosal healing after septoplasty surgery. METHOD(S): This prospective randomized observational study was conducted between July 2019 and February 2021, with 40 patients aged 18-60 years who underwent closed the only septoplasty operation for similar septal deviations. Patient divided into two group; 21 patients were placed in PRP group to which PRP was applied on all mucosal surface and submucoperichondrial area of septum and 19 patients were placed in control group to which saline solution was applied on same regions. Nasal obstruction score, mucociliary clearance time, presence of nasal crusting, and bleeding time were evaluated on 5th, 10th, 15th day after surgery and compared between groups. RESULTS: Intranasal crusting on day 10 was found to be lower in the PRP group (n:13 68.4 %) than control group (n:7 33.3 %) with a statistically significant difference (p = 0.028). The nasal obstruction score on day 10 and 15 were found to be lower in the PRP group (3,33 ± 2,75, 2,07 ± 2,20) (than the control group (5,44 ± 2,26, 3,37 ± 1,92) with a statistically significant difference (p = 0,003,p = 0,009). The mucociliary clearance rate was found to be higher and the bleeding time was found to be lower in the PRP group, but a statistically significant difference was not observed. CONCLUSIONS: Application of submucoperichondrial PRP could have beneficial effects on nasal mucosal repair, nasal crusting, and congestion after septoplasty surgery.

Surgical landmarks for identification and preservation of the internal branch of the superior laryngeal nerve.

OBJECTIVE: To determine the topographical anatomic features of the internal branch of the superior laryngeal nerve (ibSLN) at the thyrohyoid membrane entrance area in relation to certain consistent anatomical structures. MATERIALS: METHODS: Twenty-two fresh adult head cadavers (9 male, 13 female; age range 52-95 years) with no signs of abnormality in the neck were dissected to determine the anatomic relationship of ibSLN and superior border of thyroid cartilage, thyroid notch, carotid bifurcation, hyoid corpus, and hyoid greater cornu. RESULTS: The topographical relationship between ibSLN and superior border of thyroid cartilage, thyroid notch, carotid bifurcation, hyoid corpus, and hyoid greater cornu was identified bilaterally in all cadavers. According to the measures, danger zone and safe zone areas for surgical could be predicted and for surgical manipulations as well. CONCLUSION: We provided the surgical anatomy and important landmarks for determining the internal branch of superior laryngeal nerve in the thyrohyoid membrane entrance region to avoid surgical damage during surgeries of this region.

Comparison of the Otolaryngological Symptoms of Laboratory-Confirmed and Clinically Diagnosed COVID-19 Patients.

Objectives: Our aim is to determine prevalence, severity, duration of otorhinolaryngologic symptoms related to coronavirus disease 2019 (COVID-19), and correlation between the test results obtained by oronasopharyngeal swab and the symptoms of these regions by evaluating differences in ear, nose, and throat (ENT) symptoms between laboratory-confirmed COVID-19 patients and clinically and computed tomography (CT)-diagnosed COVID-19 patients. Methods: The study enrolled patients with a positive polymerase chain reaction (PCR) test diagnosed with COVID-19 that grouped as PCR (+), and those with repeated negative PCR tests but COVID-19 Reporting and Data System (CO-RADS) chest CT findings with high (CO-RADS 5) or very high (CO-RADS 6) similarity to COVID-19 that grouped as PCR(-)/CT(+). Demographic features, general symptoms, and otorhinolaryngological symptoms and severity of disease were evaluated and compared. Results: The most common ENT symptoms in the PCR(+) group were loss of taste (n=77), loss of smell, and sore throat with respective frequencies of 34.5%, 31.8%, 26.0%, and in PCR(-) CT (+) group loss of taste, loss of smell, and sore throat with respective frequencies 24.6%, 21.1%, and 18.4%. ENT symptom rates were found higher in PCR (+) group (65.0%) according to PCR(-)/CT(+) group (49.1%) with statistically significant difference (p=0.008). Loss of smell rates were found higher in PCR (+) group according to PCR(-)/CT(+) group with statistically significant difference (p=0.037). Conclusion: Loss of smell and taste were most common ENT symptoms in laboratory-confirmed COVID-19 cases. The presence of COVID-19 should definitely be considered in patients presenting with sudden loss of smell or taste. In addition, loss of smell and otolaryngologic symptoms were more common in laboratory-confirmed COVID-19 according to clinically and computed tomograpy diagnosed COVID-19 cases. There can be a correlation between positive sample region and symptom region. Location of symptoms must be considered for decision of sampling location.

What Is the Long-Term Findings of Olfactory and Taste Loss due to COVID-19?

Objectives: The objective of this study was to determine prevalance, severity, course, and long-term findings of smell and taste disorders of coronavirus disease 2019 (COVID-19) patients in mild-moderate and severe-critical disease spectrum. Methods: All adult patients conducted in our hospital with positive severe acute respiratory syndrome coronavirus 2 between March and April 2020 were surveyed during disease course and those with olfactory and taste loss were re-surveyed to determine the course and progress of these symptoms after at least 12-month follow-up. Demographic features and clinical findings were evaluated as well as disease severity. Results: A total of 77 patients with smell and/or taste loss symptoms were included in the study. At diagnosis, 58 (75.3%) patients had loss of smell and 75 (97.4%) had loss of taste. After a follow-up period of 12-14 months, 12 (15.6%) patients had ongoing loss of smell and six (8%) patients had ongoing loss of taste. Three (3.9%) patients complained of cacosmia and 5 (6.5%) complained of parosmia at follow-up. The presence of ongoing visual analog scale scores of smell and/or taste was not statistically significant between male and female patients. When presence and severity of symptoms were compared by disease severity, no statistically significant difference was found. Conclusion: Smell and taste loss seem to be among the presenting symptoms of COVID-19. The prognosis and the treatment of the smell loss and taste loss in COVID-19 patients remains unclear. To improve and accelerate recovery, the pathophysiology and the treatment options must be validated.

Giant Cell Angiofibroma in Sublingual Area: A Case Report and Review of Literature.

We present a case of Giant Cell-Rich Solitary Fibrous Tumor also known as Giant cell angiofibroma, occuring in sublingual region, to our knowledge, which has never been reported before. Forty-nine years old female who presented with painless, slowly growing mass in the sublingual region underwent excisional surgery and was diagnosed with giant cell-rich solitary fibrous tumor previously referred to as giant cell angiofibroma. In our report, we aimed to report the unusual localization of this rare tumor, examine the new nomenclature and classification of giant cell-rich solitary sibrous tumor or giant cell angiofibroma and review the literature regarding head and neck localization of this tumor.

Rhinolithiasis, a rare entity: Analysis of 31 cases and literature review.

OBJECTIVE: Rhinolithiasis is a rare condition which results from deposition of salt around a endogenous or exogenous nidus. In the literature, most of the reports are single case studies. In this study, we aimed to present the characteristics, symptoms, diagnosis, and treatment methods of 31 rhinolithiasis cases and to focus on the current literature. METHODS: We retrospectively reviewed 31 rhinolithiasis cases which have been diagnosed and treated in a tertiary care center between January 2014 and December 2018. Patient characteristics, presenting symptoms, concomitant sinonasal disorders, and type of surgery were noted. Descriptive statistics were carried out. RESULTS: Mean age was 25.4±15.7. The cases were comprised 14 female patients (45.2%) and 17 male patients (54.8%). The most common presenting symptom was nasal obstruction (71%). Malodorous unilateral rhinorrhea was present in 17 patients (54.8%). Epistaxis snoring and sleep apnea were other rare symptoms. In 21 of the cases (67.7%), rhinolith was located between inferior turbinate and septum which was the most common location seen in our series. The number of patients who were under the age of 18 was 13, in 2 of them, rhinolith was found to be formed around a plastic bead, and in 2 of them, fruit seeds were the nidus. The most common concomitant sinonasal pathology was septal deviation which was detected in 20 of the patients (64.5%), adenoid vegetation and nasal polyposis were other disorders. In 20 of the patients (64.5%), simple removal of the rhinolith using a forceps with the help of a rigid nasal endoscope was performed. Eight of the 17 patients had severe deviation and septoplasty was performed at the same time, which was the most common concomitant surgical intervention (25.8%). In 3 patients (9.6%), functional endoscopic sinus surgery was performed at the same time. CONCLUSION: Our series is one of the largest series in the literature. The most common presenting symptom was nasal obstruction followed by malodorous rhinorrhea. Accompanying sinonasal disorders should be addressed to improve the outcome. Rigid or flexible endoscopic examination should be used to detect a rhinolith. Computed tomography scan can diagnose a hidden rhinolith in a patient with nasal obstruction.

Can Hounsfield Unit Density Accurately Predict Recurrent Cholestatoma in Previously Operated Ears?

The objective of the study was to determine whether Hounsfield Unit density would differentiate between cholesteatoma and other causes of opacification, such as granulation tissue in previously operated ears. Temporal bone computer tomography (CT) scans of 47 patients, who had revision mastoid surgeries, were evaluated retrospectively. A circular 5 mm2 region of interest (ROI) was placed at aditus ad antrum to measure Hounsfield Unit (HU) density. There was no statistically significant difference between cholesteatoma and non-cholesteatoma groups in terms of HU densities. Intraclass correlation coefficient test showed an intraclass correlation of 0.41 between measurements done by radiologists and otorhinolaryngologists, which showed poor reliability. Contrary to previous studies in unoperated ears, in operated ears HU density at aditus level cannot be a reliable diagnostic adjunct. Moreover, when it is considered that interrater reliability was poor between radiologists' and otolaryngologists' measurements, a need for further studies arise to solidify findings in this study. Key Words: Cholesteatoma diagnostic imaging, Middle ear surgery, Revision mastoidectomy.

Benign Paroxysmal Positional Vertigo: Comparison of Idiopathic BPPV and BPPV Secondary to Vestibular Neuritis.

The aim of this study was to reveal clinical features of benign paroxysmal positional vertigo (BPPV) through comparing idiopathic BPPV and BPPV secondary to vestibular neuritis (VN). The clinical data of the 189 BPPV patients admitted to our tertiary care hospital including otolaryngological, audiological, vestibular, neurological, and radiological evaluations were reviewed. Patients diagnosed with idiopathic BPPV (n = 145) and BPPV secondary to VN (n = 44) were grouped as I and II, respectively. The clinical data of 2 groups were compared. The findings of the study showed that the patients with secondary BPPV due to VN are much younger, have symptoms of only posterior semicircular canal involvement, and require more treatments compared to patients with idiopathic BPPV. The clinical features of patients with BPPV secondary to VN and idiopathic BPPV differ on several aspects. More extensive studies are needed to investigate the underlying etiology in patients with BPPV encountered after VN.

The role of fine needle aspiration biopsy in deep lobe parotid tumors: Comparison of preoperative cytology and postoperative histopathologic results.

PURPOSE: Major salivary gland tumors constitute almost 3% of head and neck tumors. Tumors located exclusively in the deep lobe are not common and 20% of parotid gland tumors originate from deep lobe under the branches of the facial nerve. Accuracy of fine needle aspiration biopsy (FNAB) procedure in salivary gland tumors have been studied extensively, however there isn't any data regarding usefulness of FNAB in tumors located exclusively in deep lobe of parotid gland. In this study we aimed to assess the use of FNAB in deep lobe parotid tumors. MATERIALS AND METHODS: We retrospectively analyzed 51 patients with deep lobe parotid tumors who underwent surgery in our clinic between January 2013-December 2018. Characteristics of patients were recorded. Preoperative FNAB results and postoperative final histopathologic diagnosis were compared. Statistical analysis was performed using SPSS 24.0 was used for statistical analysis. RESULTS: The number of patients that met the inclusion criteria was 51. The mean age of patients were 49.2(14-86). In 40 (78.4) of the patients, tumor was reported as benign and in 11 (21.6) patients FNAB diagnosis was suspicious for malignancy, malignant or non-diagnostic. In final histopathologic diagnosis, 42 of the tumors were benign and 9 were malignant. The most common benign tumor type was pleomorphic adenoma which constitutes 27 of the cases (52.9%). Regarding detection of malignant disease, the sensitivity of FNAB was 90.4%, specificity was 77.7%, positive predictive value was 95%, negative predictive value was 63.6%. There was a substantial agreement between FNAB and final histopathologic diagnosis(kappa = 0,628). CONCLUSIONS: FNAB is a safe and reliable tool to evaluate deep lobe parotid tumors. It is an important part of preoperative surgical planning and can help the surgeon in patient counseling. FNAB with ultrasound guidance is recommended for deep lobe tumors.

Symptomatology of COVID-19 from the otorhinolaryngology perspective: a survey of 223 SARS-CoV-2 RNA-positive patients.

PURPOSE: To determine prevalence, severity, duration, and time from onset to diagnosis of general and Otorhinolaryngologic symptoms related to COVID-19 in whole disease spectrum: from mild to critical patients. METHODS: All adult patients with positive SARS-CoV-2 RNA found in nasopharyngeal and oropharyngeal swabs between March 10 and April 21, 2020 were surveyed by the authors for new onset symptoms during disease course. Demographic features, general symptoms, and Otorhinolaryngological symptoms were evaluated and compared by disease severity. RESULTS: Of 223 included patients, 18.4% had mild, 61.4%; moderate, 14.3%; severe, and 5.8%; critical disease. Median age was 51 (range 20-93), 113 (50.7%) were male and 110 (49.3%) were female. The most common general symptoms were fatigue, cough, and fever with respective frequencies of 71.3%, 54.3%, and 50.7%. The most common Otorhinolaryngologic symptoms were taste loss, smell loss, and sore throat with respective frequencies of 34.5%, 31.8%, and 26%. Fatigue, fever, and dyspnea were more common in severe-critical patients compared to mild-moderate patients (p = 0.029, p = 0.016, and p < 0.001, respectively). Only smell loss was more common in mild-moderate group (p = 0.003). Prevalence of other symptoms did not differ between groups. Symptom durations and onset time to diagnosis varied. CONCLUSION: When compared to the previous studies, while general symptoms were less common, Otorhinolaryngologic symptoms were more common in our study population. Considering high infection risks, Otorhinolaryngologists should be aware of COVID-19 patients presenting with Otorhinolaryngologic complaints.

Perspectives of Young Otolaryngologists on Pediatric ENT and the Future of the Field in Turkey.

OBJECTIVE: The purpose of this study was to examine the current status and the future of pediatric otolaryngology in Turkey by evaluating the opinions of young otolaryngologists on pediatric otolaryngology. METHODS: The study included 224 otolaryngology physicians who were senior residents registered with the Turkish Otolaryngology and Head-Neck Surgery Association (TORL-HNS). The physicians were in their last two years of otolaryngology training (154 physicians) or had completed their residency training and were in their first year of otolaryngology practice (70 physicians). They were approached via e-mail and Short Message Service (SMS) in October through December 2019 with a descriptive letter and asked to voluntarily complete an online questionnaire consisting of total 25 questions in five sections. RESULTS: The online questionnaire was sent to 224 physicians, and 109 (49%) participated in the survey. All 109 participants answered all the questions. Overall, 71 participants (65.1%) were in training for residency and 38 (34.9%) were in their first year of expertise. According to their professional interests, the participants listed rhinology (45 participants, 41.3%), head and neck surgery (27 participants, 24.8%), facial plastic surgery (19 participants, 17%), otology-neurotology (16 participants, 14.7%), and laryngology-phoniatry (2 participants, 1.8%) as their first preference for subspecialty. Pediatric otolaryngology was never a first choice among the participants, although four (3.7%) listed pediatric otolaryngology as their second preference. CONCLUSION: The aim of this study was to shed light on the current and future status of pediatric otolaryngology in Turkey. We believe the establishment of exclusive pediatric otolaryngology clinics under the umbrella of general ear, nose and throat (ENT) clinics and the foundation of officially approved fellowship programs would bring this subspecialty field to its deserved and desired level in our country.

Relationship between progression of type 2 diabetes mellitus and olfactory function.

OBJECTIVES: In the literature, diabetes mellitus was mentioned as one of the etiologic factors of olfactory disorder. However, association between olfactory dysfunction and complications of type 2 diabetes mellitus is unclear. The aim of this study was to determine if there is any correlation between olfactory dysfunction and complications of diabetes mellitus. METHODS: The study population included eighty-five (85) patients with type 2 diabetes mellitus (56 females and 29 males, mean age 55.4 ± 9.4 years). The routine laboratory and ophthalmoscope examinations were used in the study. The Connecticut Chemosensory Clinical Research Center odor test was performed to all patients. Patients were grouped (normal, anosmia, mild hyposmia, moderate hyposmia, severe hyposmia) in respect to olfactory function. RESULT: Distribution of the patients was 34.1% male (29) and 65.9% female (56). Mean Hemoglobin A1c value was 9.0 ± 2.7. The distribution of complications was 38.8% nephropathy, 25.9% retinopathy, 24.7% microalbuminuria. In Odor Test classification, statistically significant difference was not detected in nephropathy, retinopathy and microalbuminuria ratios (p = 0.523, p = 0.057, p = 0.993). CONCLUSIONS: This study revealed that in odor test classification, statistically significant difference was not detected between the patients with complications (nephropathy, retinopathy, and microalbuminuria) and the patients without complications.

Peritonsillar dexamethasone-bupivacaine vs. bupivacaine infiltration for post-tonsillectomy pain relief in children: a randomized, double-blind, controlled study.

OBJECTIVE: Post-tonsillectomy pain is one of the most frequent morbidities of tonsillectomy surgery. Currently, there is no standard protocol for post-tonsillectomy pain control. In our study, we aimed to compare the effects of perioperative peritonsillar dexamethasone-bupivacaine and bupivacaine-alone infiltration on pain control in pediatric patients. MATERIALS AND METHODS: This prospective, randomized, double-blind, controlled clinical trial was conducted between February 2018 and May 2018 in a single-center tertiary education and research hospital, otorhinolaryngology/head and neck surgery clinic, under general anesthesia, which included 120 pediatric patients between the ages of 2-12 (mean 5.7 ± 1.8), and who were with ASA (American Society of Anesthesiologists) I-II classification. Patients were randomly divided into three groups as 40 participants in each group. Group 1 consisted of patients who were injected with dexamethasone-bupivacaine into their peritonsillar region, group 2 consisted of patients who were injected with bupivacaine only, and group 3 consisted of patients who were injected with saline only as the control group. FLACC (face, legs, activity, cry, consolability) Scale and Wong-Baker FACES® Pain Rating Scale (WBS) were used for early and late period postoperative pain scoring. Patients with pain score ≥ 4 were treated with paracetamol rescue analgesia. Side effects such as nausea, vomiting and bleeding were recorded. Data of all groups were compared statistically and p ≤ 0.05 was considered statistically significant. RESULTS: There was no significant difference between the groups in terms of demographic data, duration of operation and duration of anesthesia. The pain scores of group 1 were significantly lower than those of the control group except for postoperative 45th min, 2nd day and 3rd day. The pain scores of the group 1 were significantly lower at all times except for the postoperative 12th and 24th hour, than those of group 2. The pain scores of the group 2 were lower than the control group only at postoperative 7th day, but no significant difference was found at other times. No statistically significant difference was found between the groups in terms of requirement rates for the first 60 min recovery analgesia (p = 0.686). No statistical difference was found between the groups in terms of side effects. CONCLUSION: In our study, preoperative local dexamethasone-bupivacaine infiltration in pediatric patients was shown to be more effective than bupivacaine-only and serum-only infiltration for early and late post-tonsillectomy pain control.

Penetrating Traumas to the Parotid Region.

Penetrating trauma to the parotid gland is a rare condition. Mostly, gunshot wounds to the parotid area are seen. Facial paralysis and sialocele formation are particular concerns and may cause significant morbidities. Early diagnosis and early exploration are crucial in the setting of facial paralysis following penetrating trauma. Sialocele formation and fistulas can be managed conservatively or surgically.

Contralateral Ear Findings in Chronic Otitis Media.

OBJECTIVES: Chronic otitis media (COM) reveals a spectrum of otoscopic findings, and both ears may be affected to a different degree. The analysis of contralateral ear in patients with COM is important to detect the early signs of the disease. This may enable the follow-up and treatment of abnormalities in contralateral ear without delay. Therefore, in this study, we aimed to investigate the otoscopic and audiologic findings of contralateral ears of patients with COM. METHODS: The institutional data of patients who underwent surgical treatment between 2014 and 2017 due to COM were reviewed. Suppurative ears with cholesteatoma, polyps, and otorrhea refractory to medical treatment and ears with dry middle ear mucosa, with otorrhea responsive to medical treatment, and without cholesteatoma were divided into two groups (Group 1 and Group 2, respectively). All patients were examined with regard to the presence of perforation, retraction, myringosclerosis, atrophy, and audiological results before the groups were compared. RESULTS: Approximately 50% of contralateral ears of patients with COM showed abnormalities at an otoscopic examination in both groups. Tympanic membrane retraction in Group 1 was greater than in Group 2, and the difference was statistically significant (p<0.05). Both the mean air and bone conduction thresholds of the contralateral ears in Group 1 were also found to be elevated when compared with Group 2, and the differences were statistically significant (p<0.05). CONCLUSION: COM may be seen bilaterally due to the same predisposing factors affecting the ears. Therefore, detection, follow-up, and early treatment of abnormalities of contralateral ear associated with otitis media have clinical importance in the prevention or delaying progression of these abnormalities to COM.
