The comparison of the histopathological results of the thyroid fine-needle aspiration biopsies in the 795 patients with thyroidectomy.

BACKGROUND: We aimed to evaluate the effectiveness of preoperative fine-needle aspiration biopsies (FNAB) by the postthyroidectomy pathology results. METHOD: Seven hundred and ninety-five patients with FNAB and following thyroid operations which have been performed between April 2008 and December 2019 were included in this study. By comparing the results of the FNAB and final pathologies, the specificity, sensitivity, FNR, false positivity ratio (FPR), accuracy and also the effect of nodule diameter on these have been evaluated. In Bethesda III subgroup according to FNAB, we investigated the malignancy rates and in whom this risk has been increased more. RESULTS: In our study, the sensitivity of FNAB is 73.40%, the specificity is 95.33%, the accuracy is 91.81%, FNR is 26.60% and FPR is 4.67%. In the patients with nodules ≥4 cm and < 4 cm respectively, we calculated the sensitivity 20.0% vs 79.76%, specificity 95.73% vs 95.19%, accuracy 89.82% vs 92.78%, FNR 80.0% vs 20.24%, FPR 4.27% vs 4.8%. CONCLUSION: Thyroid FNAB is an easy procedure with a high specificity and sensitivity. Nevertheless, when the nodule diameter was ≥4 cm, increased FNR and decreased sensitivity should be kept in mind while evaluating the patients.

Laryngoscopic Examination During the COVID-19 Pandemic: Turkish Voice Speech and Swallowing Disorders Society and Turkish Professional Voice Society Recommendations.

COVID-19 is highly transmissible and spreads rapidly in the population. This increases the occupational risk for health care workers. In otolaryngology clinic practice, patients with upper respiratory tract infection symptoms are common. Also, routine head and neck examinations such as oral cavity examination, nasal/nasopharyngeal examination, or video laryngostroboscopic evaluation are highly risky because of the aerosol formation. To emphasize this issue, two leading otolaryngology organizations in Turkey; 'Voice Speech and Swallowing Disorders Society', and 'Professional Voice Society' gathered a task force. This task force aimed to prepare a consensus report that would provide practical recommendations of the safety measurements during routine clinical care of laryngology patients. To fulfill this, universal aim, on the 2nd and 9th of May 2020, two web-based meetings were conducted by 20 expert physicians. This eighteen items list was prepared as an output.

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.

An Examination of Vocal Tract Acoustics following Wendler's Glottoplasty.

PURPOSE: To investigate the formant frequency (FF) features of transgender females' (TFs) voice after Wendler's glottoplasty surgery and compare these levels with age-matched healthy males and females. STUDY DESIGN: Controlled prospective. METHODS: 20 TFs and 20 genetically male and female age-matched healthy controls were enrolled in the study. The fundamental frequency (F0) and FFs F1-F4 were obtained from TF speakers 6 months after surgery. These levels were compared with those of healthy controls. RESULTS: Statistical analysis showed that the median F0 values were similar between TFs and females. The median F1 levels of TFs were different from females but similar to males. The F2 levels of TFs were similar to females but different from males. The F3 and F4 levels were significantly different from both male and female controls. CONCLUSION: Wendler's glottoplasty technique is an effective method to increase F0 levels among TF patients; however, these individuals report their voice does not sufficiently project femininity. The results obtained with regard to FF levels may be the reason for this problem. Voice therapy is recommended as a possible approach to assist TF patients achieve a satisfactory feminine voice.

Association of Autologous Costal Cartilage Harvesting Technique With Donor-Site Pain in Patients Undergoing Rhinoplasty.

IMPORTANCE: Postoperative pain at the donor site is a common morbidity following autologous costal cartilage grafting. OBJECTIVE: To evaluate postoperative pain at the donor site after the use of a muscle-sparing costal cartilage harvesting technique compared with a muscle-cutting technique using electrocautery. DESIGN, SETTING, AND PARTICIPANTS: Designed as a controlled trial without randomization, this prospective, comparative cohort study was conducted between January 1, 2016, and March 31, 2017. Participants included 20 patients who underwent rhinoplasty for various cosmetic and functional complaints from January 1, 2016, to February 28, 2017. Of the 20 patients, 1 was excluded owing to an infection that developed on postoperative day (POD) 7. Patients were grouped by the rib harvesting technique used that was either a muscle-sparing technique (n = 11) or a muscle-cutting technique (n = 8). Skin incisions for both groups were carried out with a blade. Transection of muscle fascia and muscle fibers was performed with monopolar electrocautery in the muscle-cutting technique group. Blunt dissection with a hemostat was performed in the muscle-sparing technique group. All other surgical techniques were identical. MAIN OUTCOMES AND MEASURES: Postoperative pain was assessed with visual analog scale scores for resting pain and movement pain. Eight pain measurements were noted at the sixth postoperative hour and on PODs 1, 2, 3, 7, 15, 30, and 45. During the hospital stay, the postoperative need for analgesics was recorded daily as the number of analgesic infusion vials used. RESULTS: The 19 patients in the study included 11 women and 8 men whose mean age (SD) was 33.2 (10.3) years The mean (SD) visual pain analog scale scores for resting pain and movement pain were consistently higher in the muscle-cutting technique group than in the muscle-sparing technique group. This difference was statistically significant on PODs 2, 3, and 15 for resting pain and on PODs 2, 3, 7, 15, 30, and 45 for movement pain. The mean postoperative need for analgesic infusion vials during hospital stay was higher in the muscle-cutting technique group, and the difference was statistically significant on POD 2 (1.9 [0.6] vials vs 1.0 [0.9] vials; P = .02). CONCLUSIONS AND RELEVANCE: Both resting and movement pain at the donor site was significantly reduced in the muscle-sparing technique group during the postoperative period, findings that align with anecdotal reports in the literature. Routine use of the muscle-sparing technique in autologous costal cartilage harvesting is recommended to reduce postoperative pain. LEVEL OF EVIDENCE: 2.

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.

An objective assessment of halitosis in children with adenoid vegetation during pre- and post-operative period.

OBJECTIVES: Although most specialists in otorhinolaryngology and pediatrics find halitosis to be a common problem in children with adenoid hypertrophy, there are no objective data on this topic in the literature. Whether adenoid hypertrophy is a risk factor for halitosis or whether halitosis is a sign of adenoid hypertrophy remains unclear. Thus, the aim of this study was to investigate whether children diagnosed with adenoid hypertrophy have a higher probability of halitosis than do children in the normal population and whether adenoidectomy can decrease oral malodor. METHODS: Forty children with adenoid hypertrophy and 40 healthy subjects aged 5-15 years were included in the study. The children with adenoid hypertrophy underwent adenoidectomy operations and were followed for 3 months. We measured volatile sulfur compounds (VSCs), hydrogen sulfide (H2S), methyl mercaptan (CH3SH), and dimethyl sulfide (CH3)2S using an objective method, a portable gas chromatograph (OralChroma; AbiMedical, Osaka, Japan). RESULTS: The mean CH3SH and (CH3)2S levels were significantly different (p < 0.05) between the adenoid hypertrophy group and the controls. The H2S, CH3SH, and (CH3)2S levels in the third postoperative month were significantly lower (p < 0.05) than those in the preoperative period, and there was no significant difference postoperatively between the patients with adenoid hypertrophy and controls. There was a positive correlation between age and VSC levels, and CH3SH levels were significantly higher in patients with ventilation tube insertion, rather than just adenoidectomy. CONCLUSIONS: There was a statistically significant association between halitosis and adenoid hypertrophy, and a significant improvement in halitosis was obtained following adenoidectomy. The present study provides an association between halitosis and adenoid hypertrophy. If there is no other oral pathology causing halitosis, halitosis can be a sign of adenoid hypertrophy in children.

Prognostic factors in type I tympanoplasty.

OBJECTIVE: To identify the preoperative factors that influence the success rate of type I tympanoplasty. METHODS: A total of 247 type I tympanoplasty procedures were included in the present study. We determined the effects of the following preoperative variables on the anatomical and functional outcomes of type I tympanoplasty in order to identify prognostic preoperative factors: age (<16 years vs. >16 years), history of ear surgery, state of the contralateral ear (healthy vs. diseased), size of perforation, presence of septal pathology, presence of adenoid disease and history of smoking. Additionally, we stratified the surgical procedures according to the type of graft materials used and analyzed the effects of the above preoperative variables on the success rates of each type of procedure separately in order to eliminate the confounding effect of surgical technique. RESULTS: The study was conducted on 217 subjects (130 females, 87 males) who underwent a total of 247 surgical procedures. The graft take rate was significantly higher after tympanoplasty with perichondrium-cartilage island flap (PCIF) grafts than after tympanoplasty with temporalis fascia (TF) grafts (87.8% vs. 72.3%, p=0.008). Young age (p=0.013), presence of adenoid hypertrophy (p=0.001) and abnormality of the contralateral ear (p=0.027) were associated with lower success rates after tympanoplasty with TF grafts. The success rate of tympanoplasty with PCIF grafts was not affected by any of the preoperative variables we tested. Postoperative audiometry showed that the improvement in hearing ability did not differ between patients who received TF grafts and those who received PCIF grafts (p=0.325). CONCLUSION: Tympanoplasty with cartilage grafts was associated with better graft takes and comparable hearing outcomes than those associated with tympanoplasty with TF grafts. In patients with risk factors such as contralateral ear disease, a young age or adenoid disease, cartilage-perichondrium grafts are preferable to TF grafts.

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.

The effect of medical treatment on voice quality in allergic rhinitis.

To evaluate the change in the voice quality of patients with allergic rhinitis (AR) after medical treatment. The study enrolled 69 subjects: 39 with high serum-specific IgE levels to inhalant allergens as the study group and 30 healthy individuals as controls. All patients were evaluated using the total nasal symptom score (TNSS) and voice handicap index-10 (VHI-10) and then underwent an acoustic voice analysis. After 1 month of treatment with mometasone furoate nasal spray (two 50-µg puffs in each nostril once daily) and desloratadine (5-mg tablet once daily), the patients repeated the surveys and acoustic voice analysis. The results before and after treatment were compared. The TNSS and VHI-10 scores decreased significantly after treatment (p < 0.01). After treatment, the acoustic analysis parameters improved significantly and were similar to the control group, and the maximum phonation time increased significantly (p < 0.05). The voice quality of patients with AR is improved with medical treatment.

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.
