Elevated serum calprotectin as an inflammatory marker in obstructive sleep apnea.

OBJECTIVE: To investigate the serum calprotectin (SCal) levels and neutrophil/lymphocyte ratio (NLR) values in patients with obstructive sleep apnea (OSA). METHODS: Sixty-seven OSA patients and 46 healthy volunteers without any sleep disorders were included in the study. The patient group was divided into three subgroups according to the severity of OSA. The SCal levels and NLR values were compared among subgroups and between the experimental and control groups. RESULTS: The mean SCal level and NLR value were higher in the study group than in the control group (p = 0.002 and p = 0.001, respectively). The SCal levels were significantly higher in patients with severe OSA than in those with moderate and mild OSA (p = 0.004 and p = 0.001, respectively). DISCUSSION: Unlike NLR, the SCal level may inform the severity of OSA and could be used as an indicator for OSA.

Impact of Nasal Trauma on Olfactory Function.

OBJECTIVE: To determine the impact of nasal trauma with and without the potential to produce nasal fracture on the olfactory function. STUDY DESIGN: A descriptive analytical study. PLACE AND DURATION OF STUDY: Ear, Nose, Throat Clinic, Ankara Numune Training and Research Hospital, Ankara from October 2018 to June 2019. METHODOLOGY: The study included patients with nasal trauma and control subjects. The patients with nasal trauma were divided into two groups as fracture group (Group F, n=83) and non-fracture group (Group Non-F, n=30). The Group F was further divided into two subgroups according the presence as septal fracture as Group SF (patients with septal fracture) and Group Non-SF (patients with non-septal fracture). The smell functions of all participants were evaluated using the Sniffin' Sticks test. The odour scores of Group F and Group Non-F were compared versus control group, using the independent sample t-test or Mann-Whitney U-test. Percentage of patients with olfactory dysfunction was compared between Group F and Group Non-F and between Group SF and Group Non-SF using the Chi-square test. RESULTS: There were a total of 113 participants with mean age of 35.64±10.44 years. The median TDI score of Group F was significantly lower in comparison to control group, no significant difference was found between Group Non-F and control group in terms of median TDI score. There was a significant difference between Group F and Group Non-F in terms of the percentage of patients with olfactory dysfunction. No significant difference was found between Group F and Group Non-F with respect to the percentage of patients with olfactory dysfunction. CONCLUSION: Nasal trauma can lead to olfactory dysfunction only if it has the potential to produce a nasal fracture. Key Words: Smell disorders, Nasal bone, Bone fractures, Trauma.

The Protective Effect of Platelet Rich Plasma Against Cisplatin-Induced Ototoxicity.

Cisplatin, a pharmacological agent widely used for treating many cancers, may cause serious side effects including ototoxicity, nephrotoxicity, and peripheral neuropathy. The present study aimed to investigate whether platelet-rich plasma (PRP) protects against cisplatin ototoxicity. Eight rats (16 ears) were divided into 2 groups: control group (4 rats, 8 ears) that received intratympanic saline and study group (4 rats, 8 ears) that received intratympanic PRP. Cisplatin (10 mg/day intraperitoneally) or vehicle was administered 2 times per day to the animals. Auditory brainstem responses were recorded preoperatively and postoperatively on day 4 and at week 3. The authors compared the morphological appearances of spiral ganglion cells and the organ of Corti and the density of spiral ganglion cells between treatment groups. The number of outer hair cells in the organ of Corti significantly decreased in the control group compared with that in the PRP group. Although no statistically significant difference was observed between the groups regarding ABR thresholds on day 4 (P = 0.083, a statistically significant difference was observed between groups at week 3 (P = 0.038). Our results suggest that PRP can prevent cisplatin-induced ototoxicity.

Evaluation of Liver Functions Based on Serum Aminotransferase Enzyme Levels in Patients with Obstructive Sleep Apnea Syndrome.

Obstructive sleep apnea syndrome (OSAS) is associated with fatty liver disease. In the present study, relations between alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels and the severity of OSAS and polysomnography parameters were investigated. The study included 194 patients with OSAS and 114 control patients. The patients underwent an overnight polysomnography (PSG) in the Sleep Laboratory. ALT and AST levels were compared between the patients and the controls and between the subgroups of the patients. ALT and AST levels were also compared with the PSG parameters REM AHI, NREM AHI and minimum O2 saturation separately. The mean ALT was 28.95 in the patients and 17.85 in the controls (p < 0.001) with a statistically significant difference and the mean AST was 23.62 in the patients and 16.53 in the controls with a statistically significant difference (p < 0.001). The patients with OSAS had significantly higher ALT and AST levels. The higher the ALT and AST levels were, the more severe the disease was, though the differences between the subgroups of the patients were not significant.

The Effect of Anterior Palatoplasty Plus Modified Expansion Sphincter Pharyngoplasty on Voice Performance in Obstructive Sleep Apnea Syndrome.

OBJECTIVE: We aimed to investigate the effect of anterior palatoplasty (AP) plus modified expansion sphincter pharyngoplasty (MESP) on voice performance in patients with obstructive sleep apnea syndrome (OSAS). METHODS: Fourteen OSAS patients who had AP + MESP procedure were included in the study. Voice performances of the patients were analyzed with acoustic voice analysis before surgery, and 6 months after surgery. RESULTS: Preoperative and postoperative F0, jitter percentage, and shimmer percentage were compared. Mean preoperative F0 was 129.85 Hz, and mean postoperative F0 was 138.07 Hz, with a significant difference in between (P = 0.017). Mean preoperative jitter percentage was 0.65, and mean shimmer percentage was 0.88, while those values were 0.67 and 0.84, respectively, in the postoperative period. The differences were not statistically significant (P = 0.801 and 0.652). CONCLUSION: The AP + MESP procedure performed for OSAS results in improvement of F0 in the long term; however, there were no differences in jitter percentage and shimmer percentage.

A New Predictor for Obstructive Sleep Apnea Syndrome: Monocyte to HDL Ratio.

The aim of this study was to investigate the relation of serum monocyte to serum HDL cholesterol ratio with obstructive sleep apnea syndrome (OSAS). A total of 336 patients who underwent polysomnography (PSG) were included in this study. The individuals with an apnea hypopnea index (AHI) <5/h were included in the study as controls while the patients with an AHI > 5 and excessive daytime sleepiness were included in the study as OSAS patients. OSAS patients were compared with the control group for serum monocyte count, high density lipoprotein (HDL) levels, and monocyte to HDL ratio (MHR). Mild, moderate and severe OSAS subgroups were compared for the same parameters. Additionally, correlations of serum monocyte count, HDL level and MHR with other PSG parameters were analyzed. The mean MHR of control and OSAS groups were 12.90 ± 6.64 and 4.91 ± 6.98, respectively, and the difference was statistically significant (p = 0.041). Mean HDL level of the control group was 47.25 ± 13.61 mg/dL while it was 43.14 ± 13.61 mg/dL in OSAS group (p < 0.001). Comparison of OSAS subgroups for MHR and HDL levels revealed statistically significant differences (p < 0.001 and p = 0.020, respectively). MHR was higher in OSAS patients compared to the controls. MHR may be a new, useful predictor for OSAS.

Does Tonsillectomy Affect Voice in Early or Late Postoperative Periods in Adults?

OBJECTIVE: The aim of our study was to investigate the short- and long-term effects of tonsillectomy on voice performance in adults. STUDY DESIGN: Prospective cohort study. MATERIALS AND METHODS: This study was conducted between January 2013 and June 2015. A total of 26 adults who had tonsillectomy due to chronic tonsillitis or recurrent acute tonsillitis were included in the study. The voice performances of the participants were analyzed with objective and subjective methods before surgery, and 1 and 3 months after surgery. An acoustic voice analysis (fundamental frequency [F0], jitter %, shimmer %) was performed for objective analysis, and Voice Handicap Index survey was used for subjective analysis of the voice. Preoperative F0, jitter %, shimmer %, and Voice Handicap Index values were compared with the values obtained 1 and 3 months after surgery. RESULTS: Impairment of voice performance was determined when preoperative and postoperative first month F0, jitter %, and shimmer % values were compared. Three months after surgery, those values were found similar to the preoperative values. CONCLUSION: Tonsillectomy affects voice performance negatively in adults in short term; however, it does not affect voice performance in long term after surgery.

A Comparison of Cartilage Palisades and Temporal Fascia in Type 1 Tympanoplasty for Bilateral Tympanic Membrane Perforations in Children.

OBJECTIVE: To compare the graft success rates and audiological outcomes of bilaterally performed type 1 tympanoplasty using cartilage palisades or temporal fascia in children. MATERIALS AND METHODS: We retrospectively analyzed the medical records of patients who underwent type 1 tympanoplasty at Medical Park Hospital between May 2007 and February 2013. 27 patients (54 ears) were enrolled in the study: 15 (30 ears) in the palisade cartilage group and 12 (24 ears) in the fascia group. RESULTS: The graft success rate for the fascia group was 79.2%, and that for the cartilage group was 96.7%. The difference was statistically insignificant (p=0.078). Audiological improvements were seen in both groups, and the difference was statistically insignificant. CONCLUSION: The use of temporalis fascia grafting has similar outcomes to palisade cartilage tympanoplasty for both success rate and audiological values in children who have bilateral disease.

Comparison of Hyaluronic Acid Fat Graft Myringoplasty, Fat Graft Myringoplasty and Temporal Fascia Techniques for the Closure of Different Sizes and Sites of Tympanic Membrane Perforations.

OBJECTIVE: To compare the efficacy of three different myringoplasty techniques, namely hyaluronic acid fat graft myringoplasty (HAFGM), fat graft myringoplasty (FGM), and temporal fascia for the closure of different sizes and sites of tympanic membrane perforations. MATERIALS AND METHODS: We retrospectively analyzed the medical records of patients who had undergone a type 1 tympanoplasty operation at our clinic between May 2007 and February 2013. The patients were divided into three groups depending on the patient's choice of technique as follows: Fat Graft Myringoplasty (FGM) (Group I), Hyaluronic Acid Fat Graft Myringoplasty (HAFGM) (Group II), and Temporalis Fascia (TF) (Group III). A total of 136 patients were included in the study, split in to the FGM (57 patients; 56.1% female; median age: 30 years), HAFGM (31 patients; 54.8 female; median age: 25 years), and TF (48 patients; 58.3% females; median age: 33 years) surgery technique groups. RESULTS: The patients were further divided into two groups, depending on the size of the perforation (small and large), and into three groups, depending on its location (anterior, inferior, and central). None of techniques provided a significantly better success rate in terms of perforation location (p>0.05). Also, none of the techniques provided a significantly better success rate in terms of perforation size (p>0.05). CONCLUSION: We propose using HAFGM for large perforations and FGM alone for small perforations. The TF technique is a successful and well-defined technique for tympanic membrane perforations; however, in our opinion, its technical difficulties make it a secondary choice, particularly for small-sized perforations.

The Effect of Septoplasty on Voice Performance in Patients With Severe and Mild Nasal Septal Deviation.

OBJECTIVE: The authors aimed to analyze the effect of septoplasty, performed in 2 groups with different grades of nasal septal deviation (NSD), on voice performance. METHODS: A total of 43 patients who had septoplasty due to NSD and were included in the study. The study groups were divided into 2 groups as groups A and B. The patients in group A had severe NSD, and 1 of the nasal cavity was obstructed totally or near totally. In group B, the NSD narrowed the nasal passage, and the deviation was not severe. The voice performance was analyzed preoperatively, and 1 month after surgery with both objective and subjective methods. Objective analysis included acoustic voice analysis, and measurement of F0, jitter %, shimmer %. Preoperative and postoperative F0, jitter %, shimmer %, and Voice Handicap Index-30 (VHI-30) were compared in groups A and B. RESULTS: F0 showed a statistically significant improvement after surgery in group A (P <0.001). Jitter %, shimmer %, and VHI-30 scores also improved after surgery, without any statistical significance. In group B, preoperative and postoperative F0, jitter %, and shimmer % were similar. However, VHI-30 scores showed a significant improvement postoperatively (P = 0.005). Comparison of groups A and B for improvements of the voice parameters revealed that group A showed improvements in all voice parameters, and the improvements of F0 and shimmer % were statistically significant. CONCLUSION: Septoplasty performed for severe NSD obstructing nasal lumen totally or near totally results in significant improvements in the voice performance.

Results of ossicular chain reconstruction with glass ionomer cement in pediatric patients.

OBJECTIVE: The aim of our study was to analyze the hearing results of ossicular chain reconstruction in incus long process defects in pediatric patients. METHODS: This retrospective study included 15 pediatric patients that had incus long process defect due to chronic otitis media or adhesive otitis, and repaired with glass ionomer cement between 2009 and 2015. The audiological tests (air conduction thresholds, bone conduction thresholds, air bone gap) obtained preoperatively and one year after surgery were compared. In addition, preoperative and postoperative air bone gap differences were estimated to determine hearing gain. RESULTS: Mean air conduction and air bone gaps decreased significantly one year after surgery when compared to the preoperative values (p< 0.001 for both). Mean hearing gain was 20.33±6.36dB one year after surgery. CONCLUSION: Use of glass ionomer cement to repair incus long process defects is a suitable method that improves hearing in pediatric patients. Further large studies that compare glass ionomer cement ossiculoplasty with other ossicular reconstruction methods are needed.

Relation of otosclerosis and osteoporosis: A bone mineral density study.

OBJECTIVE: Otosclerosis and osteoporosis are metabolic bone diseases. In this paper, we investigated presence of osteoporosis with bone mineral density test in patients who had surgery for otosclerosis. METHODS: We included 27 patients who had conductive hearing loss and diagnosed with otosclerosis during an exploratory tympanotomy, and 30 healthy controls into this study. Bone mineral densitometry test was used for analysis of osteoporosis. T-scores of the patients and the controls obtained from L1-L4 vertebrae and femur neck were compared. In addition, the relations of duration of the disease, air and bone conduction thresholds, and air-bone gap in the operated ear with 25(OH)D3 levels, T-scores obtained from L1-L4 vertebrae and femur neck were investigated in the otosclerosis group. RESULTS: T-score obtained from L1-L4 region was -1.14±1.05 in the otosclerosis group, and was -0.56±1.10 in the control group; the difference was statistically significant (p=0.045). The T-scores obtained from the femur neck were -0.59±0.82 and 0.03±0.74 in the otosclerosis and the control groups respectively, with a statistically significant difference in between (p=0.004). As the air and bone conduction thresholds and the air-bone gaps of the patients with otosclerosis increased, 25(OH)D3 levels and T-scores decreased, but the differences were not statistically significant. CONCLUSION: The relation between otosclerosis and osteoporosis was shown with bone mineral density test in our study. T-scores of the otosclerosis patients were found smaller than the normal population.

[The relationship between platelet count and mean platelet volume with obstructive sleep apnea syndrome]. / Trombosit sayisi ve ortalama trombosit hacminin tikayici uyku apne sendromu ile iliskisi.

OBJECTIVES: This study aims to investigate the relationship between platelet count and mean platelet volume (MPV) with obstructive sleep apnea syndrome (OSAS). PATIENTS AND METHODS: This retrospective study included 417 OSAS patients (284 males, 133 females; mean age 47.9±10.0; range 23 to 75 years) who were performed polisomnography (PSG) in our clinic between January 2013 and December 2014. Patients were divided into two groups according to apnea-hipopnea index (AHI). Apnea-hipopnea index <5 was assumed as normal, while AHI ≥5 was assumed as OSAS. Platelet count and MPV values of group with normal AHI and group with OSAS were statistically compared. Apnea-hipopnea index, REM AHI, non-REM AHI, minimum oxygen saturation, and duration of oxygen saturation remaining below 90% were statistically compared with platelet count and MPV. RESULTS: The mean of platelet count in non-OSAS and OSAS groups were 262.31±65.78 and 252.77±61.86, respectively, with no statistically significant difference between the groups. Mean platelet volume in non-OSAS and OSAS groups were 9.56±1.88 and 9.71±1.57, respectively; however, the difference was not statistically significant. Platelet count increased statistically significantly as AHI, REM AHI, non-REM AHI, and minimum oxygen saturation parameters got impaired. CONCLUSION: As PSG parameters get impaired, platelet count increases in OSAS patients.

Relationship Between Neutrophil to Lymphocyte Ratio, Platelet to Lymphocyte Ratio and Obstructive Sleep Apnea Syndrome.

BACKGROUND: Neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) give information about many diseases. An increase in inflammation markers occurs in patients with obstructive sleep apnea syndrome (OSAS). OBJECTIVES: The aim of this study is to determine the relationship between OSAS and NLR and PLR values. MATERIAL AND METHODS: Two hundred eighty four patients with complaints of snoring and excessive daytime sleepiness were included in the study. Polysomnography had been performed on all patients and the control group. Fourty eight of these patients with apnea-hypopnea index (AHI) less than 5 (pure snoring) were included in the control group, 67 patients with AHI between 5 and 14.9 in the mild OSAS group, 61 patients with AHI between 15 and 29.9 in the moderate OSAS group and 108 patients with AHI more than 30 in the severe OSAS group. NLR and PLR values were calculated from the complete blood count (CBC) analysis of the patients and control group. The OSAS and control groups were compared by age, gender, body mass index (BMI) and PSG parameters as well as NLR and PLR values. RESULTS: The PLR value in the OSAS group was found to be less than in the control group (p=0.006). As the non-REM AHI increased, the value of PLR decreased. As the nocturnal time spent with arterial oxygen saturation<90% increased, the value of NLR was determined to increase. CONCLUSIONS: NLR and PLR values can give valuable information in OSAS.

Single-Nucleotide Polymorphisms on the RYD5 Gene in Nasal Polyposis.

Nasal polyposis (NP) is a chronic inflammatory disease. Several genes play major roles in the pathophysiology of the disease. We analyzed RYD5 gene polymorphisms to determine the effect of these variants or their genetic combinations on NP. We genotyped the RYD5 gene in 434 participants (196 patients with NP and 238 controls). Data were analyzed with SPSS, SNPStats, and multifactor dimensionality reduction (MDR) software. We genotyped 10 single-nucleotide polymorphisms (SNPs) in the RYD5 gene. RYD5 (+152G>T) (p.Gly51Va) has not been reported previously. The PolyPhen and PROVEAN predicted the missense mutation as deleterious, but sorting intolerant from tolerant (SIFT) did not. In the genotype analysis, we found that four SNPs (RYD5 [-264A>G], [-103G>A], [+57-14C>T], and [+66A>G]) were significantly associated with NP. The individuals with combined genotypes of six risk alleles (RYD5-264G, -103A, +13C, +57-14T, +66G, and +279T) had significantly higher risks for NP compared with the ones with one or four risk alleles. Haplotype analysis revealed that the two haplotypes were associated with risk of NP. As indicated by MDR analysis, RYD5 (-264A>G and -103G>A) and RYD5 (-264A>G, -177C>A, and -103G>A) were the best predictive combinations and they had the highest synergistic interaction on NP. In addition, RYD5 (+13C>T) was significantly associated with increased risk of both NP with asthma and NP with allergy and asthma. Some SNPs and their combinations in the RYD5 gene are associated with increased probability for developing NP. We emphasize the importance of genetic factors on NP and NP-related clinical phenotypes.

New Predictive Parameters of Bell's Palsy: Neutrophil to Lymphocyte Ratio and Platelet to Lymphocyte Ratio.

BACKGROUND: Bell's palsy is the most frequent cause of unilateral facial paralysis. Inflammation is thought to play an important role in the pathogenesis of Bell's palsy. AIMS: Neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) are simple and inexpensive tests which are indicative of inflammation and can be calculated by all physicians. The aim of this study was to reveal correlations of Bell's palsy and degree of paralysis with NLR and PLR. STUDY DESIGN: Case-control study. METHODS: The retrospective study was performed January 2010 and December 2013. Ninety-nine patients diagnosed as Bell's palsy were included in the Bell's palsy group and ninety-nine healthy individuals with the same demographic characteristics as the Bell's palsy group were included in the control group. As a result of analyses, NLR and PLR were calculated. RESULTS: The mean NLR was 4.37 in the Bell's palsy group and 1.89 in the control group with a statistically significant difference (p<0.001). The mean PLR was 137.5 in the Bell's palsy group and 113.75 in the control group with a statistically significant difference (p=0.008). No statistically significant relation was detected between the degree of facial paralysis and NLR and PLR. CONCLUSION: The NLR and the PLR were significantly higher in patients with Bell's palsy. This is the first study to reveal a relation between Bell's palsy and PLR. NLR and PLR can be used as auxiliary parameters in the diagnosis of Bell's palsy.

[New predictive parameters of nasal polyposis: neutrophil to lymphocyte ratio and platelet to lymphocyte ratio]. / Nazal polipte yeni öngörücü parametreler: Nötrofil lenfosit orani ve trombosit lenfosit orani.

OBJECTIVES: This study aims to investigate the correlations between nasal polyposis (NP) and NP density with neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR). PATIENTS AND METHODS: The study included 105 patients (72 males, 33 females; mean age 41.33±12.85 years; range 16 to 63 years) diagnosed as NP (NP group) and 83 healthy individuals (54 males, 29 females; mean age 44.01±8.50 years; range 18 to 62 years) (control group). Nasal polyposis density score was calculated with preoperative Lund-Mackay computed tomography grading system. Neutrophil to lymphocyte and PLR ratio values of NP and control groups were calculated and statistically compared. Neutrophil to lymphocyte and PLR values were statistically compared in terms of NP density in the NP group. RESULTS: Mean NLR value was 2.26 in the NP group and 1.75 in the control group with a statistically significant difference (p=0.001). Mean PLR value was 120.79 in the NP group and 109.84 in the control group with a statistically insignificant difference (p=0.073). CONCLUSION: Neutrophil to lymphocyte ratio value may be used as a novel marker that is easily administered in patients with nasal polyps and obtained with low-cost tests. New studies with larger patient series are needed for the value of PLR.

Prognostic effect of hyperbaric oxygen therapy starting time for sudden sensorineural hearing loss.

Sudden sensorineural hearing loss is one of the otological emergencies whose pathogenesis is uncertain and associated with total or partial loss of hearing function. The aim of this study was to investigate whether the hyperbaric oxygen therapy starting time affects the management of sudden sensorineural hearing loss. Fifty-nine patients with sudden sensorineural hearing loss admitted to our clinic between 2008 and 2012 were retrospectively included in this study. All patients received hyperbaric oxygen therapy. In addition, each patient received intravenous piracetam and 37 patients received steroid therapy. Hyperbaric oxygen therapy was initiated between 1 and 7 days with 20 patients determined as Group A, between 8 and 14 days with 25 patients determined as Group B and between 15 and 28 days with 14 patients determined as Group C. Hearing gains of these three groups were statistically evaluated. Each of them showed statistically significant improvement. Lowest hearing gain was observed in Group C and the gain of this group was statistically less than the other two groups. There was no significant difference between the hearing gains of the Group A and Group B. Starting hyperbaric oxygen therapy in patients with sudden sensorineural hearing loss within the first 14 days has positive effect on the prognosis of the disease.

The effect of obstructive sleep apnea syndrome and continuous positive airway pressure treatment on voice performance.

OBJECTIVE: Obstructive sleep apnea syndrome (OSAS) may affect voice performance due to alterations that occur in the upper respiratory tract. The aim of the study was to assess the effect of OSAS and continuous positive airway pressure (CPAP) treatment on voice performance. MATERIALS AND METHODS: Twenty-seven patients with moderate to severe OSAS (apnea-hypopnea index ≥15/h) who underwent polysomnographic examination and 28 age- and gender-matched normal control subjects were enrolled in the study. The patients and the control subjects completed Voice Handicap Index (VHI) questionnaires, and their acoustic voice analyses were performed. Fundamental frequency (F0), jitter %, and shimmer % parameters were statistically compared. Acoustic analyses were performed again 1 month after regular CPAP use in OSAS patients, and the parameters before and after the treatment were compared. RESULTS: F0 was 160.82 Hz, jitter was 0.70%, shimmer was 1.05%, and VHI was 1.18 in the control group. In OSAS patients before CPAP treatment, F0 was 157.04 Hz, jitter was 0.82%, shimmer was 1.33%, and VHI was 13.11. These results showed that shimmer and VHI parameters were significantly worse in OSAS patients. After CPAP treatment, F0 was 169.19 Hz, jitter was 0.62%, shimmer was 0.93% and VHI was 5.00. The differences were statistically significant in all parameters. CONCLUSION: The acoustic parameters of OSAS patients differed from those of the normal control subjects. The patients' voice performance improved after a regular use of CPAP treatment for 1 month.

The correlation between clinical prediagnosis and pathology results in the diagnosis of neck masses.

The importance of clinical assessment and its contribution to the diagnosis of neck masses was investigated in patients presenting with a neck mass. In our study, we collected the medical history of a total of 127 patients, including 66 males and 61 females, who presented with a neck mass. Physical exams, endoscopic examinations, laboratory tests, a variety of imaging studies, and fine-needle aspiration biopsies were performed. The relationship between age, duration and location of the neck mass, FNAB results, and definitive histopathological diagnosis were investigated as well as the correlation between the consensus diagnosis reached after the evaluation of the medical history, physical examination and imaging studies, and definitive histopathological diagnosis. A strong and positive relationship (p < 0.01) was found between patients' ages and the definitive diagnosis established by histopathological examination. There was no statistically significant relationship (p > 0.05) between the duration and location of the neck mass and definitive diagnosis established by histopathological examination. And no statistically significant relationship (p > 0.05) was found between FNAB results and definitive histopathological diagnosis. Although no statistically significant relationship was found between the characteristics of neck masses and age, duration and location of masses and FNAB results, there was a statistically significant correlation between the pre-diagnosis estimated by ENT specialists and definitive diagnosis established by histopathological examination. A strong and positive relationship (p < 0.01) was found between clinical pre-diagnosis and definitive diagnosis established by histopathological examination. In patients presenting with a neck mass, the diagnosis should be made based on the medical history, physical examination, radiologic imaging and FNAB results, treatment decisions should be based on those findings.
