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 follow-up results of newborn hearing screening of Gaziosmanpasa Taksim Research and Training Hospital.

AIM: This study aimed to present the results of newborns who were referred to advanced audiology centers after newborn hearing screening, and to determine concordance of our results with the American Academy of Pediatrics guidelines about the ages of hearing loss, aid fitting, and cochlear implantation. MATERIALS AND METHODS: A total of 7502 newborns were screened in Gaziosmanpasa Taksim Research and Training Hospital between March 2014 and June 2016 using the transient otoacustic emissions test as the first two steps and automated auditory brainstem response test for the third step. Newborns who had risk factors were screened using the automated auditory brainstem response only. Newborns who failed the screening tests were referred to advanced audiology centers. RESULTS: Of the 7502 newborns, 6736 (90%) completed the screening. The ratio of hearing loss was 0.08%. Six of 62 newborns who failed auditory brainstem response test and were referred to advanced audiology centers had severe bilateral hearing loss. One of the patients was not fitted with a hearing aid because the family refused it. The other one was not fitted an aid and did not undergo cochlear implantation because of severe and treatment-resistant acute otitis media. The age of diagnosis for the rest was before three months, and except for one patient, hearing aid fitting was before six months. The age of cochlear implantation was 12 months for two patients and 14 months for two patients. CONCLUSION: Ninety percent of patients completed the screening, the age of diagnosis for hearing loss was before three months and aid fitting was before six months, except for one patient. The results of the study were compatible with the diagnosis and treatment guidelines of the American Academy of Pediatrics.

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.

Modified Mallampati Score Improves Specificity of STOP-BANG Questionnaire for Obstructive Sleep Apnea.

BACKGROUND: An accurate, clinical screening tool for obstructive sleep apnea (OSA) that identifies patients for further diagnostic testing would assist in the diagnosis of this comorbidity. One example, the STOP-BANG questionnaire (SBQ), has been validated as a screening tool with high sensitivity. However, its specificity may result in a high false-positive rate. The aim of this study to determine if addition of the Modified Mallampati score to the SBQ improves its specificity. METHODS: The authors studied 162 patients referred to the Sleep Disorders Clinic at Yedikule Chest Disease Education and Research Hospital. All patients were prospectively screened for risk of OSA using the SBQ, their oral anatomy was assessed by Modified Mallampati scoring, and sleep quality characterized by polysomnography. Polysomnography results were reviewed when available and the predictive performance of the SBQ and the modified SBQ scoring models were compared. RESULTS: In the authors' study an SBQ score ≥3 yielded sensitivities of 0.85, 0.86, and 0.91 for Apnea-Hypopnea Index (AHI) ≥5/h, AHI ≥15/h, and AHI ≥30/h, respectively, and specificities of 0.09, 0.10, and 0.18. The modified SBQ with a cutoff of ≥4 (>3) points for AHI levels of >5, >15, and >30 yielded respective sensitivities of 0.84, 0.86, and 0.91 and specificities of 0.25, 0.26, and 0.27. CONCLUSIONS: The author's results from indicated the modified SBQ with a cutoff of >3 points in this study was more specific than the standard SBQ but no less sensitive, and may be used in identifying OSA patients for further diagnostic evaluation or avoiding unnecessary testing.

An assessment of olfactory function in patients with laryngopharyngeal reflux disease.

CONCLUSIONS: The results reported here indicate that there was a statistically significant difference in the olfactory functions of laryngopharyngeal reflux patients vs the healthy group. To the best of the authors' knowledge, this study is the first to evaluate the olfactory function of patients diagnosed with laryngopharyngeal reflux using an objective method, 24-h pH monitoring. OBJECTIVES/HYPOTHESIS: The aim of this study was to investigate olfactory functions in laryngopharyngeal reflux (LPR) patients and compare the results with healthy controls. METHODS: A total of 60 participants; 30 men and women with a diagnosis of laryngopharyngeal reflux and 30 healthy controls, were included in the study. Patients in the laryngopharyngeal reflux group were evaluated by the Reflux Symptom Index (RSI), Reflux Finding Scores (RFS), and finally 24-h pH monitoring to confirm the diagnosis of laryngopharyngeal reflux. The Sniffin' Sticks olfactory test results of the laryngopharyngeal reflux and control groups were compared, and the relationship between the study findings and the olfactory parameters were evaluated. RESULTS: The odor threshold, odor discrimination, odor identification, and TDI scores of the laryngopharyngeal reflux group were significantly lower than those of the control group. Also there was a statistically significant negative correlation detected between the olfactory test and some symptom and finding scores.

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.

Does iron deficiency anemia affect olfactory function?

Conclusion This study found a negative effect of IDA on olfactory function. IDA leads to a reduction in olfactory function, and decreases in hemoglobin levels result in further reduction in olfactory function. Objective This study examined the effects of iron-deficiency anemia (IDA) on olfactory function. Method The study enrolled 50 IDA patients and 50 healthy subjects. Olfactory function was evaluated using the Sniffin' Sticks olfactory test. The diagnosis of IDA was made according to World Health Organization (WHO) criteria. Results Patients with IDA had a significantly lower threshold, discrimination, and identification (TDI) value, and a lower threshold compared with the control group. However, there were no significant differences between the groups in terms of smell selectivity values.

Helicobacter pylori in lacrimal secretions.

The aim of this study was to investigate the presence of Helicobacter pylori in human lacrimal and nasal secretions. Eighty patients with complaints of dyspepsia who had undergone endoscopies and gastric antrum biopsies were included in the study. A total of five specimens, including 2 lacrimal secretion samples, 2 nasal mucosal swab samples, and 1 gastric antrum biopsy, were collected from each patient and investigated with polymerase chain reaction (PCR) methods consisting of the urease enzyme coding gene GlmM (UreC) and the H pylori-specific 16S rRNA coding gene. The Reflux Symptom Index and ophthalmologic complaints of the patients were recorded. The detected positivity rates of the H pylori 16S rRNA coding gene in gastric biopsies and nasal mucous and lacrimal secretions were 55, 11.2, and 20%, respectively. The patients were grouped as gastric-antrum-biopsy-negative (Group I [n = 36]) and -positive (Group II [n = 44). In Group II, H pylori positivity in the lacrimal and nasal mucous secretions was 36.3 and 18%, respectively. A comparison between the groups in terms of H pylori presence in nasal mucous and lacrimal secretions yielded statistically significant differences (p = 0.0001, p = 0.003). The simultaneous presence of H pylori in nasal mucous and lacrimal secretions was 13.6% in Group II. H pylori positivity in nasal mucous and lacrimal secretions had a positive moderate correlation (r = 0.40; p = 0.0003). The present study is the first report on the presence of H pylori in lacrimal secretions through nested PCR, which suggested the presence of a number of mechanisms for H pylori transmission to lacrimal secretions.

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.

A new horizon in the treatment of biofilm-associated tonsillitis.

OBJECTIVE: To demonstrate the efficacy of tonsil brushing in patients with chronic tonsillitis to remove the microbial biofilm on the tonsil surface using an in vitro model. DESIGN: Specimens from patients undergoing tonsillectomy were evaluated prior to and following surface cleaning methods, including rinsing and brushing, using scanning electron microscopy (SEM). PATIENTS: The study population consisted of 25 randomly selected patients with chronic tonsillitis. INTERVENTIONS: Specimens were collected and divided into four portions. Each portion received distinct surface cleaning methods and was immediately fixed for SEM examination. OUTCOME MEASURES: The biofilm layer on the surface of the tonsils was examined using SEM. The density of the biofilm layer and the degree of persistence of the biofilm after rinsing and brushing were measured. RESULTS: The surface biofilm of the tonsils in the first group, which were neither brushed nor rinsed, revealed a thick layer of biofilm on the mucosal surface. The second group of tonsils, which were only rinsed, also showed a thick layer of biofilm. The third group of tonsils, which were rinsed following gentle brushing using a soft toothbrush, showed a reduction in the thickness of the biofilm layer. The fourth group of tonsils, which were brushed with a hard brush, was almost devoid of a biofilm layer. CONCLUSION: Our results demonstrate that rinsing does not effectively remove the biofilm layer on the tonsil surface. The use of a harder brush was identified as a more powerful means of removing biofilm compared with a soft brush.

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.

Postnatal risk factors associated with hearing loss among high-risk preterm infants: tertiary center results from Turkey.

The aim of this study was to determine the postnatal risk factors associated with hearing loss as well as the prevalence of hearing loss among high-risk preterm infants in newborn hearing screening (NHS). We performed a retrospective study of high-risk preterm infants born with a gestational age ≤32 weeks and/or a birth weight ≤1,500 g. A NHS procedure was performed by automated auditory brainstem response (AABR) and automated evoked otoacoustic emission (TEOAE). Infants who failed TEOAE or AABR or both tests were referred to a tertiary audiology center for diagnosis confirmation and management. Postnatal risk factors associated with hearing loss were evaluated and compared for preterm infants with and without hearing loss. 1,360 high-risk preterm infants were assessed. Permanent hearing loss was found in 19 (1.4%) infants. Multivariate analysis revealed that proven sepsis (p = 0.019), mechanical ventilation ≥5 days (p = 0.024), loop diuretics (p = 0.001), patent ductus arteriosus ligation (p = 0.018) and operation for retinopathy of prematurity (ROP) (p = 0.034) were significant related factors for the hearing loss. This study showed a low prevalence of hearing loss and an association between operation for ROP and hearing loss in preterm infants, which has not been defined previously. Our results suggest that every neonatal intensive care unit should determine their own risk factors and take precautions to prevent hearing loss for these high-risk preterm infants.

The effect of duration of merocel in glove finger with tetracaine solution on septoplasty morbidity.

OBJECTIVE: We aimed to decrease the postseptoplasty morbidities depending on nasal packing by using Merocel within glove finger moistened with tetracaine 0.25% solution. STUDY DESIGN: The study was designed as a randomized prospective study. SETTING: A university hospital in Turkey. SUBJECTS AND METHODS: Our study consisted of 80 patients who underwent septoplasty. The Merocel nasal tampon within glove finger was inserted after surgery in the study group and removed after 24 or 48 hours. Merocel was moistened with tetracaine 0.25% solution after insertion into the nasal cavity and just before removal. The morbidities and normal breathing time were recorded and compared with those of the control group. RESULTS: The postseptoplasty morbidities were significantly decreased in the study group compared with those in the control group. The morbidities were also improved after removal of tampons after 24 hours compared with 48 hours. However, the normal breathing time was prolonged when the nasal tampons were removed after 24 hours. CONCLUSIONS: The glove finger provides comfortable removal of nasal packing. The Merocel tampons might be safely removed just after 24 hours postoperatively without any complication.

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.

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.
