Eustachian tube diameter: Is it associated with chronic otitis media development?

OBJECTIVE: To evaluate the effect of ET diameter on Chronic Otitis Media (COM) pathogenesis. STUDY DESIGN: Retrospective. SUBJECTS AND METHODS: Patients with unilateral COM disease are included in the study. The connection between fibrocartilaginous and osseous segments of the Eustachian Tube (ET) on axial Computed Tomography (CT) images was defined and the diameter of this segment is measured. The measurements were carried out bilaterally and statistically compared. RESULTS: 154 (76 (49%) male, 78 (51%) female patients were diagnosed with unilateral COM and included in the study. The mean diameter of ET was 1947mm (Std. deviation±0.5247) for healthy ears and 1788mm (Std. deviation±0.5306) for diseased ears. The statistical analysis showed a significantly narrow ET diameter in diseased ear side (p<0.01). CONCLUSION: The dysfunction or anatomical anomalies of ET are correlated with COM. Measuring of the bony diameter of ET during routine Temporal CT examination is recommended for our colleagues.

How can periorbital oedema and ecchymose be reduced in rhinoplasty?

Oedema and ecchymose are frequent morbidities of septorhinoplasty, a facial surgical procedure for reforming the shape and functions of the nose. Periorbital oedema (PO) and periorbital ecchymose (PE) are normal occurrences, but are undesirable for patients undergoing the procedure for aesthetic purposes. The present study examined 65 patients who underwent open technique septorhinoplasty for aesthetic and functional complaints. Patients were divided into two groups: Group 1 patients underwent lateral osteotomy following tip plasty, at the end of the surgical operation; Group 2 patients underwent lateral osteotomy before tip plasty, at the beginning of the surgical operation. Patients were followed on the postoperative first, third and seventh days. PO and PE values of patients were scored from 0 to 4. The plastering time (Pt) was significantly shorter for Group I than Group II (p < 0.05). The total surgical time (T) showed no significant difference (p > 0.05). The PO value at the first, third and seventh days was significantly smaller for Group I than Group II (p < 0.05). The PE value at the first, third and seventh days was also significantly smaller for Group I than Group II (p < 0.05). The obtained data indicate that performing a lateral osteotomy in the final stages of surgery, and subsequently applying a nasal plaster and splint as rapidly as possible, decreases PO and PE in the postoperative period.

The Effects of Nasal Packing and Transseptal Suturing After Septoplasty on Olfactory Function, Patient Comfort, and Mucociliary Clearance.

BACKGROUND: This study compared the effects of nasal packing and transseptal suturing after septoplasty by evaluating olfactory function, pain, and mucociliary clearance. METHODS: The study enrolled 39 patients diagnosed with isolated septal deviation. The patients were randomly assigned to 2 groups. In Group A (n = 21), transseptal sutures were placed for septal stabilization after the septoplasty. In Group B (n = 18), both nasal passages were packed with Merocel tampons after the septoplasty. It was made Sniffin Sticks test, sacchranirine test, and pain and discomfort scales preoperatively, 1 week postoperatively and 3 months postoperatively on all patients. RESULTS: There was no postoperative bleeding, submucoperichondrial haematoma, or abscess formation in either group. The postoperative discomfort and pain scores were increased in Group B (the packing group) in our study, the mucociliary clearance improved after septoplasty in both groups, and there was no significant difference in mucociliary clearance between the 2 groups. The odor threshold, odor identification, and odor discrimination were significantly increased 3 months postoperatively, but not 1 week postoperatively. CONCLUSIONS: Nasal packing causes more discomfort and pain than transseptal suturing, while there was no significant difference in olfactory functions or the mucociliary clearance after septoplasty between nasal packing and transseptal suturing.

Effects of Spreader Grafts on Olfactory Function in Septorhinoplasty.

BACKGROUND: Following rhinoplasty, the cross-sectional parts of the nose may be significantly reduced, and nasal air movement and olfaction may be altered. Studies on olfactory function after surgical procedures are quite limited and have largely focused on sinus surgery or septoplasty. OBJECTIVES: The objective of this study is to assess the consequences of spreader grafts on olfactory function. METHODS: This prospective study was conducted at the Gaziosmanpasa Taksim Education and Research Hospital, Department of Otolaryngology, from January 2014 to June 2015. In total, 68 patients who had undergone an open-technique septorhinoplasty were included. In 35 patients, bilateral spreader grafts were included with the open septorhinoplasty (group 1), and 33 patients underwent open septorhinoplasties without spreader grafts (group 2). RESULTS: The age and gender distributions of the patients in the two groups did not differ (p > 0.05). Preoperative threshold, discrimination, and identification values in both groups did not differ (p > 0.05). In groups 1 and 2, postoperative threshold values were significantly higher than preoperative values (p < 0.05). The change in threshold, discrimination, and identification level was significantly higher postoperatively versus preoperatively in group 1 (p < 0.05); however, the changes in discrimination and identification values did not significantly differ between in group 2 (p > 0.05). CONCLUSIONS: Our study demonstrates the superior widening effect of spreader grafts over the nasal valve and favorable results in olfactory function in primary septorhinoplasty patients.

Peak nasal inspiratory flowmetry for selection of patients for radiofrequency ablation of turbinates.

OBJECTIVES: Our goals were to investigate (I) the effectiveness of the topical vasoconstrictor test (TVT) and peak nasal inspiratory flow (PNIF) measurement for the selection of patients with inferior turbinate hypertrophy (ITH) who will benefit from radiofrequency ablation (RFA) of the turbinates and (2) the efficacy of the TVT and PNIF in follow-up of treatment outcomes. METHODS: Patients with bilateral chronic nasal obstruction due to ITH underwent assessment with a visual analog scale (VAS) and PNIF before and after the TVT. Twenty patients with symptom improvement according to VAS and PNIF results were enrolled in the study. These patients underwent RFA, and PNIF and VAS scores were determined before and I and 6 months after the TVT. These results were compared to evaluate the preoperative prediction of RFA treatment success. RESULTS: Radiofrequency ablation of the turbinates resulted in significant changes in objective and subjective scores. Preoperative (baseline) subjective and objective responses to decongestant were positively correlated (P = .024 and P < .05, respectively). Preoperative (baseline) objective responses to decongestant were significantly correlated with the objective outcomes of surgery (P = .006 and P < .05, respectively). CONCLUSION: The combined use of PNIF and the TVT allows for the preoperative prediction of the success of RFA and the selection of patients who will benefit most from RFA.

Does rhinoplasty reduce nasal patency?

OBJECTIVE: This study aimed to evaluate the effect of rhinoplasty on subjective and objective assessment of nasal patency in patients who underwent rhinoplasty for cosmetic reasons only. SETTING: Tertiary referral center. DESIGN: Prospective, clinical study. SUBJECT AND METHODS: A total of 50 adult patients who underwent rhinoplasty were included in the study. Preoperative and postoperative photographs of the nasal profile (frontal, lateral, and oblique) were obtained. The visual analog scale (VAS) was used for the subjective evaluation of nasal obstruction (0 being the minimum, 10 being the maximum amount of nasal patency). Objective evaluation of nasal obstruction was performed with a peak nasal inspiratory flowmeter (PNIF). RESULTS: Preoperative mean VAS scores and PNIF values of the patients were 7.36 ± 0.83 and 115.10 ± 17.45, respectively. Postoperative mean VAS scores and PNIF values of the patients were 7.42 ± 0.73 and 115.30 ± 16.7, respectively. There was no statistically significant difference between any of the pre- and postoperative subjective and objective parameters (P > .05). CONCLUSION: Reduction rhinoplasty has been shown not to reduce nasal patency.

Bacteriological evaluation of tonsillar microbial flora according to age and tonsillar size in recurrent tonsillitis.

Although numerous studies based on the bacteriology of the tonsil have been carried out, none of them analyzed the variation of tonsillar flora with respect to both age and tonsillar size. The purpose of this study was to isolate the facultative and obligate anaerobes both from the surface and the core of tonsils in recurrent tonsillitis as well as to analyze the variation of isolated bacterial strains according to age and tonsillar size. A prospective study was performed on 111 patients who underwent tonsillectomy. We analyzed the differences between the bacterial pathogens in recurrent tonsillitis and semi-growth estimates with regard to age and tonsillar grade. Among 111 cases, 604 bacterial strains of 21 different from the tonsil superficial and core were isolated. The most common facultative anaerobic species isolated from the surface and core were Coagulase-negative staphylococci, Alpha-hemolytic streptococci and Diphtheroid bacilli in all subgroups except patients below 8 years old. The most commonly obligate anaerobic species isolated from the core were Propionibacterium acnes, Prevotella melaninogenica and Peptostreptococcus anaerobius. We found no significant difference in the cultured bacteria with respect to age and tonsillar size. The study subgroups did not differ in the occurrence of semiquantitative growth estimates of 3-4+. Our study demonstrates that there is polymicrobial aerobic and anaerobic flora in tonsils with regardless of patient's age and tonsillar size. This polymicrobial spectrum of bacteria may contribute to recurrence and to the failure of conservative treatment of these cases and therefore leads to surgical therapy.

Histopathologic changes in the middle ear mucosa after exposure to pepsin and unconjugated bile acid.

OBJECTIVE: An increasing number of studies indicate that pepsin and bile acid cause damage to the ear, nose, and throat structures as a result of extraesophageal reflux. The aim of this study was to evaluate and compare the damaging effect of bile acids and pepsin on the middle ear mucosa. MATERIAL AND METHODS: Twenty-nine healthy rats were included in this study. The animals were divided into 5 groups. A single daily dose of 40 µmol/L chenodeoxycholic acid, 40 µg/mL pepsin, and saline were injected separately into the right middle ear of the rats. On day 30, all rats were decapitated, and formalin-fixed, paraffin-embedded samples of the middle ear both from the control and experimental rats were prepared. A semiquantitative analysis was performed. RESULTS: Inflammatory response was seen in all middle ear mucosa of rats except control group 1. The degree of inflammatory response was higher in the bile acid group when compared with the other groups. Epithelial metaplastic changes with varying number of goblet cells were observed in both the bile acid- and pepsin-injected groups. These metaplastic changes were also higher in the bile acid-induced group than in the pepsin-injected group. CONCLUSIONS: This is the first study on the middle ear mucosal damage of both pepsin and bile acid. Our results demonstrate that bile acids were associated with more extensive mucosal injury at pH 7 in comparison to pepsin in a rat animal model. Inflammatory response and metaplastic changes may play an important role in the etiology of middle ear pathologies.

Differences in Mucociliary activity of volunteers undergoing Ramadan versus Nineveh fasting.

This study, aimed to evaluate the difference in mucociliary clearance among volunteers who underwent Ramadan versus Nineveh fasting regimens as well as the difference between the fasting period and 4 weeks following the fasting period in both groups. In this study, two different fasting groups were established: Ramadan (fasting for an average of 15 h for 29 consecutive days, n = 40) and Nineveh (60 h of nonstop fasting, n = 26). Subjects in each group underwent saccharin testing twice: at the end of the fasting period prior to resumption of eating and at 4 weeks after the end of Ramadan or Nineveh fasting. Statistical analysis was performed using the Mann-Whitney U-test, Wilcoxon, Chi-square, and paired t test. A p value less than 0.05 was considered statistically significant. Forty subjects who underwent Ramadan fasting and 26 subjects who underwent Nineveh fasting were included in this study. Of the 66 study participants, 34 (51.5 %) were men and 32 (48.5 %) were women. Their median age was 31 years (range 17-70 years) for Nineveh fasting subjects and 40 years (range 17-70 years) for Ramadan fasting subjects. Chi-square tests revealed no significant difference between the Ramadan and Nineveh fasting groups in gender (p = 0.418), and the Mann-Whitney U-test showed no difference in age. A statistically significant difference was found in the mucociliary clearance time between the Nineveh fasting and non-fasting periods (p = 0.013). Using Wilcoxon signed-rank tests, we found no significant difference in the mucociliary clearance time between the Ramadan fasting and control (4 weeks after the fasting period) periods (p = 0.121). The percentage difference between the fasting and control periods was similar between groups and was not statistically significant for the Ramadan and Nineveh fasting groups (p = 0.086). The results of the present study indicated that long-term fasting with hypohydration contributed to the deterioration of nasal mucociliary clearance. Our data indicate that optimal hydration, sleep patterns, and fasting times contribute to proper mucociliary clearance.

Oto-toxic effect of gastric reflux.

The reflux of gastric content from the nasopharynx into the middle ear via the Eustachian tube may disrupt inner ear functions. The purpose of this study was to investigate the effect of experimental gastric reflux on the cochlear function of rats. Twelve rats were included in this study. Acidified gastric pepsin was prepared by the addition of HCl and deionized water to pepsinogen from porcine stomach. The left ears were designated as the experimental ears, and the solution was delivered daily for 30 days. The control ears received an equal amount of a saline solution. Distortion product otoacoustic emissions were recorded at baseline (before the injection) and on days 3, 10, and 30. When the mean baseline distortion product otoacoustic emission measurements were compared with the final mean measurements on day 30, the acidified gastric pepsin caused statistically significant (P < 0.05) hearing loss in the experimental ears. There was no significant change in the hearing of the control ears. This is the first study on the ototoxicity of acidified gastric pepsin. Our results demonstrate that acidified gastric pepsin causes hearing loss due to inner ear ototoxicity in a rat animal model.

A rare tumor of the parapharyngeal space: angiomyxolipoma.

Parapharyngeal space tumors are uncommon, most are salivary gland tumors (50%), and they are often pleomorphic adenomas. Neurogenic tumors are the second most common primary tumors of all neoplasms in the parapharyngeal space (30%). Angiomyxolipoma is a very rare form of lipoma. Up until now, only 12 cases located on different sides of the body were reported. Presented here is a case report of a patient with an angiomyxolipoma of the parapharyngeal space. A 17-year-old boy had a slowly growing, painless mass on the left side of the neck. During the oropharyngeal examination, medial displacement of the left tonsilla palatina was observed. Magnetic resonance imaging findings were of a 6 × 5.5 × 3-cm "dumbbell"-shaped parapharyngeal mass. A fine needle aspiration of the mass showed no specific histopathology. The patient underwent a transparotid-transcervical approach for the excision of the tumoral mass under general anesthesia. Although an angiomyxolipoma is a rare form of lipoma, it is a pathology that should be kept in mind for the differential diagnosis of parapharyngeal tumors.

The effect of the duration of merocel in a glove finger on postoperative morbidity.

We examined the effects of the duration of keeping a Merocel nasal packing in the nose and the application technique (packing applied either directly or inside a glove finger) on postoperative morbidity and complications. The study included 129 patients (67 males and 62 females; age range 18 to 56 years) undergoing nasal septoplasty without turbinate intervention. The patients were randomly assigned into 4 groups. In group 1 and group 2, Merocel was directly applied in the nasal cavity for 24 hours and 48 hours, respectively; in group 3 and group 4, Merocel was kept in the nasal cavity in a powder-free glove finger for 24 hours and for 48 hours, respectively. Pain and discomfort scores were evaluated by a visual analog scale. The time taken between removal of the tampon and when the patients began to breathe comfortably was called the nasal obstruction time. The differences in mean discomfort score between the groups were not statistically significant (P > 0.05), while the mean pain scores were statistically higher in groups 1 and 2 than in groups 3 and 4 (P < 0.05). The nasal obstruction time was statistically shorter in groups 2 and 4 than in groups 1 and 3 (P < 0.05). Therefore, keeping Merocel inside a glove finger in place for 48 hours notably reduces the pain occurring during the removal of the nasal tampon. It also reduces nasal obstruction time and prevents synechia, leakage, bleeding, and septal hematoma, without compromising patient comfort.

Effect of thermal welding tonsillectomy on emergence agitation.

: This study sought to examine the effect of thermal welding tonsillectomy that reduces pain and length of anesthesia on emergence agitation. A total of 60 patients (age range, 3­6 years) with chronic recurrent tonsillitis with an indication for tonsillectomy were included. Patients were randomly assigned to 2 groups. The control group (the CD group) was composed of patients undergoing cold dissection (CD) tonsillectomy. The study group (TW group) included patients undergoing thermal welding (TW) tonsillectomy. All patients were given sevoflurane as an anesthetic agent. For all patients, anesthesia time, operation time, extubation time, Pediatric Anesthesia Emergence Delirium scale, pain scale, nausea/vomiting score, and delivery time were recorded. The duration of anesthesia, operation, and delivery was significantly lower in the TW group as compared with the CD group (P = 0.000 < 0001). The pain and agitation scores were significantly lower in the TW group as compared with the CD group (P = 0.000 < 0001). We assume that, besides reducing pain and allowing surgery without bleeding, the TW tonsillectomy method diminishes emergence agitation induced by anesthetic agents, such as sevoflurane.

Relationship between oral anaerobic bacteria and otitis media with effusion.

OBJECTIVE: In this study hypothesing the translocation of oral bacteria from oropharynx into the middle ear cavity may be involved in the pathogenesis of otitis media with effusion (OME), we aimed to investigate the presence and similarity of Fusobacterium nucleatum and Treponema denticola in saliva, nasopharyngeal secretion and the middle ear effusion samples from the children with OME. METHODS: Totally 20 children with OME undergoing myringotomy and ventilation tube placement were attended. Stimulated saliva samples were collected after otorhinolaryngological and oral examinations were done. The middle ear effusion and nasopharyngeal secretions were collected during the operations. The presence of F. nucleatum and T. denticola were detected using 16SrRNA-based PCR. The clonal similarities of the bacteria were detected in the samples which the same bacteria had been detected in each samples of the same child. After DNA sequencing, clonal similarity was determined by 16SrRNA gene clone library analysis. The sequences from each clone were compared with similar sequences of reference organisms by FASTA search. RESULTS: T. denticola was detected only in four (20%) saliva and in one (5%) nasopharyngeal sample. F. nucleatum was detected in 11 (55%) saliva, eight (40%) nasopharyngeal and six (30%) middle ear effusion samples. Sequences from F.nucleatum clones derived from three different anatomic sites within patients were similar in 33% of OME patients, indicating their genetic relatedness. CONCLUSIONS: Bacteria involved in this process most likely originate from the oropharynx since they show a close genetic relatedness with their oropharyngeal counterparts.

Relationship between the branches of the recurrent laryngeal nerve and the inferior thyroid artery.

OBJECTIVES: The relationship between the recurrent laryngeal nerve (RLN) and the inferior thyroid artery (ITA) is an important and helpful landmark for isolating the RLN and its branches during surgery. In the present study, we aimed to define and classify in detail all of the possible relationships between the two anatomic structures and their branches. METHODS: We examined 100 specimens (200 sides) from cadavers of 76 men and 24 women who were between 16 and 90 years of age at the time of death. After anatomic dissection was performed, the relationship between the RLN and the ITA was noted for each side and documented in the form of high-resolution photographs. RESULTS: The relationships of both structures and their branches were classified into 6 types. Details were verified regarding the relationships between the main trunks, between the trunks and branches, and between the branches, as follows: type A (ITA trunk to RLN trunk); type B (ITA branches to RLN trunk); type C (ITA trunk to RLN branches); type D (ITA branches to RLN trunk and RLN branches); type E (ITA branches to RLN branches); and type F (others). CONCLUSIONS: Despite the various anatomic and surgical studies already performed, in the present study we tried to demonstrate all types of relationships between the RLN and the ITA and their branches and devise a new, detailed classification of the possible relationships between the two structures.

Original Research: Aerosolized Lidocaine: Effective for Safer Arousal After Suspension Laryngoscopy.

AIM: To examine the systemic and local effects of the lidocaine on the larynx and trachea which is applied after the end of the surgery and through various application methods. STUDY DESIGN: Randomized controlled prospective study. METHOD: The study is composed of patients who underwent suspension laryngoscopy (SL) for benign laryngeal diseases (cysts, polyp, granuloma, etc) and American Society of Anesthesiologists (ASA) I, between January 2017 and January 2018. The patients were randomly divided into 3 groups. In the first group nothing is applied at the end of the surgery and called as control group, second group received 7 pufs of aerosolized 10% lidocaine solution (70 mg) over larynx and trachea and third group received cotton swaps that impregnated in 1 ml of 20 mg lidocaine solution over surgical area for 1 minutes. Operation and arousal times, heart rate and mean arterial blood pressure levels were noted and compared. Also laryngospasm, cough, and agitation scores were obtained during arousal. RESULTS: 64 patients were included in the study. Laryngospasm was not observed in any of the patients. In group 2 (aerosolized lidocaine group), patients' blood pressure remained similar while increased in other groups (P < 0.05). Agitation scores were significantly lower in group 2 compared to the other groups (P = 0.012). Cough reflex is observed less in group 2 but result was not statistically significant (P = 0.13) CONCLUSION: The usage of aerosolized lidocaine after suspension laryngoscopy is very effective in blocking the stimulation of superior laryngeal nerve and sympathetic nerves which were responsible for the pressor reflexes. The inhibition of these reflexes before or during arousal could secure a safer arousal.

Risk Factors and Diagnostic Methods in Vocal Cord Mucosal Lesions.

OBJECTIVES: This study was an examination of malignancy risk determined according to clinical characteristics and preoperative diagnosis in vocal cord lesions compared with the definitive pathology results. METHODS: This was a retrospective study of the files of patients who were admitted to a clinic due to hoarseness and/or a laryngeal lesion and underwent a suspension laryngoscopy (SL) between 2014 and 2018. The patient files were examined and the parameters of age, gender, smoking status, alcohol use, and the site of the lesion were compared for the risk of malignancy. The details of the preoperative diagnoses, peroperative findings, and definite pathology results were evaluated for agreement. RESULTS: In all, 296 cases were reviewed. Since some patients had undergone multiple SL procedures, only the final pathology results of these patients were included in the study and the final total was 260 patients. The study population consisted of 191 (73.5%) male and 69 (26.5%) female patients. Of the group, 169 (65%) were smokers and 13 (5%) consumed alcohol. The lesions were left-sided in 106 (40.8%), right-sided in 120 (46.2%), and bilateral in 34 (13.1%) cases. A total of 68 (26.2%) cases were malignant, 165 (63.5%) were benign, and 27 (10.4%) were determined to be premalignant. Analysis of patient age revealed that the risk of malignancy was significantly higher in patients in the fifth or sixth decade of life (p<0.001). Examination of gender and the risk of malignancy indicated that 64 (94.1%) of the malignant patients were male and 4 (5.9%) were female (p<0.001). It was also found that 64 of the malignant patients (94.1%) were smokers (p<0.001). Only 8 (11.8%) of the patients with malignant lesions used alcohol, and no significant relationship was found (p=0.018). The association of malignancy with the lesion site was similar (p=0.89). Logistic regression analysis determined that male gender increased the risk of malignancy 6.45% and smoking increased the risk 7.81%. CONCLUSION: Microscopic examination of the lesion and palpation are very important in the diagnosis of patients with hoarseness and laryngeal lesion. Smoking, advanced age, and male gender increased the risk of malignancy of vocal cord lesions.

Diagnosis and treatment of laryngopharyngeal reflux: Use of empirical lansoprazole.

The objective of this study was to evaluate the effectiveness of empirical medical treatment in patients with laryngopharyngeal reflux (LPR) disease by scoring the findings and symptoms. Hence, 122 patients were examined at the voice laboratory with a laryngovideostroboscopic device, and all results were recorded for further evaluation. Patients were treated with lansoprazole twice a day. All patients were evaluated before and during the treatment period at the first and third months. The reflux symptom index (RSI) and reflux finding score (RFS) records were correlated and statistically tested to confirm a diagnosis of LPR. The results revealed a significant improvement in the findings and symptoms due to this treatment modality and showed that RFS and RSI were correlated with LPR disease, which can help confirm its diagnosis. Findings and symptom scores before and after the treatment were compared. The differences were statistically significant, which strengthens the reliability of the score indices that were used. This study shows that RFS, RSI, and empirical treatment may be a useful, practical method of diagnosing and following up on LPR. We concluded that it is more efficient to score symptoms and findings together, instead of monitoring pH for 24 hours, in patients with potential LPR.

The importance of voice analysis in evaluating the effectiveness of reflux treatment.

OBJECTIVES: This study aims to investigate the effects of reflux treatment in voice disorders in laryngopharyngeal reflux (LPR) patients using acoustic analyses and the relationship between scoring systems. PATIENTS AND METHODS: A total of 84 LPR patients (18 males, 66 females; mean age 43.1±11.3 years; range 18 to 73 years) were evaluated using reflux symptom index (RSI), reflux findings score (RFS), videolaryngostroboscopic examination, and acoustic analysis with Dr. Speech 4 before LPR treatment and at the first and third months after treatment. RESULTS: Maximum phonation time, fundamental frequency (F0), jitter, and shimmer scores did not show any statistically significant alteration at the posttreatment period according to pretreatment scores (p>0.05). However, the alteration in Harmonics-to-Noise ratio and Signals-to-Noise ratio scores were statistically significant (p=0.017 and p=0.003, respectively). Reflux symptom index results showed significant positive correlation with F0 at the pretreatment, and at posttreatment first and third month evaluations (Spearman's rank correlation coefficient [rho]=0.246, p=0.024; rho=0.300, p=0.006; rho=0.305, p=0.005, respectively). CONCLUSION: The relationship between the parameters of acoustic analysis and RSI and RFS values seems to be controversial for diagnosis and follow-up of LPR patients, requiring further investigations.
