The Long Term Results of Hyaluronic Acid/Dextranomer Injection Laryngoplasty in Unilateral Vocal Fold Paralysis.

OBJECTIVE: This study was conducted to present the long-term functional outcomes of injection laryngoplasty (IL) with hyaluronic acid/dextranomer (HA/D) in unilateral vocal fold paralysis (UVFP). METHODS: A total of 40 patients who underwent HA/D injection for UVFP were enrolled. The acoustic analysis of the voice was evaluated with jitter percentage, shimmer percentage, maximum phonation time, harmonics-to-noise ratio, and fundamental frequency. The psychosocial effect of the voice was determined using the Voice Handicap Index-10. Fiberoptic endoscopic evaluation of swallowing was performed and 2 scales were used for quantification: a modified penetration-aspiration scale and a dysphagia score. All measurements were performed at preoperative day and postoperative months 1, 6, and 24. RESULTS: A statistically significant improvement was observed for all of the evaluated parameters except the maximum phonation time for postoperative months 1, 6, and 24 (P < .05). In the evaluation of the maximum phonation time, although there was a significant improvement for the postoperative months 1 and 6, no significant difference was observed between the postoperative 24th month and the preoperative value. CONCLUSIONS: HA/D injection laryngoplasty is an effective method both in the short- and long-term to improve voice and swallowing functions in patients with UVFP.

A case of oculoglandular tularemia resistant to medical treatment.

Tularemia is a zoonotic disease of the northern hemisphere. Oculoglandular tularemia is the rarest form, comprising 1.4-4.2% of all cases. We present a patient with oculoglandular tularemia that did not respond to gentamicin to demonstrate the need for prolonged antimicrobial treatment and surgical intervention.

Functional Outcomes of the Hyaluronic Acid Injections in Patients Who Underwent Partial Laryngectomy.

OBJECTIVE: The purpose of this study was to investigate the effects of hyaluronic acid injection on dysphagia, aspiration, and voice problems in patients with persistent functional problems despite appropriate rehabilitation after partial laryngectomy. METHODS: Seventeen patients who underwent hyaluronic acid injection due to persistent swallowing, aspiration, and voice problems after partial laryngectomy surgery were included in the study. The hyaluronic acid injection was performed after 2 years of follow-up after partial laryngectomy surgery. Evaluation of swallowing was performed through a fiberoptic endoscopic evaluation of swallowing and was quantified using two scales: a dysphagia score and a modified penetration-aspiration scale. Voice Handicap Index-10 was used for the determination of the psychosocial handicapping effects of the voice. Jitter percent, shimmer percent, fundamental frequency, harmonics-to-noise ratio, and maximum phonation time were evaluated for the acoustic analysis of the voice. All measurements were performed at preoperative day and postoperative months 1, 6, and 24. RESULTS: A statistically significant improvement was observed for all of the evaluated parameters except the harmonics-to-noise ratio for postoperative months 1 and 6 (P < 0.05). There was no statistically significant difference between the postoperative sixth month and the preoperative value of the harmonics-to-noise ratio. A statistically significant improvement was observed between the postoperative 24th month and preoperatively for jitter percent, shimmer percent, fundamental frequency, maximum phonation time, dysphagia, and penetration aspiration score (P < 0.05). CONCLUSION: Surgical rehabilitation should be considered along with conservative treatments to improve swallowing and voice function after partial laryngectomy. Hyaluronic acid injection may be an effective method both in the short and long term for the surgical rehabilitation of persisting functional problems that may occur following partial laryngectomies.

Shepard grommet tympanostomy tube complications in children with chronic otitis media with effusion.

The objective of this study was to determine tympanostomy tube complications in children with chronic otitis media with effusion who were treated with Shepard grommet tympanostomy tube insertion. This tube type was selected as it is the most commonly used one in our clinic. The medical records of 162 ears of 87 children (52 male and 35 female) were reviewed retrospectively. The children were between 3 to 16 years old (mean age = 8.1 +/- 3.1). The patients were followed up 6-66 months (mean 23.3 +/- 14.9 months) after tympanostomy tube insertion. We reviewed age, sex, time to tube extrusion and complications. In all patients the indication for surgery was chronic middle ear effusion. Otorrhea occurred in nine ears (5.6%). Granulation tissue was seen in two ears (1.2%). Complications after tympanostomy tube extrusion included myringosclerosis (34.6%), persistent perforation (5.6%), atrophy (23.5%), retraction (16.7%) and medial displacement of tubes (1.2%). The average extrusion time was 8.5 +/- 4.6 months (range 1-24) for Shepard grommet tympanostomy tubes. Complications of tympanostomy tube insertion are common. Myringosclerosis, tympanic membrane atrophy and otorrhea are the most frequently appearing complications. But they are generally insignificant and cosmetic. Consequently, in the majority of these complications there is no need for any management.

Analgesic efficacy of topical tramadol in the control of postoperative pain in children after tonsillectomy.

PURPOSE: Pain control after tonsillectomy is still a controversial issue. Topical approaches have the advantage of pain control with good patient acceptability. Therefore, this study was conducted to evaluate the effects of topical tramadol on postoperative pain and morbidity in children undergoing tonsillectomy. METHODS: A prospective, randomized, double-blind, controlled clinical study was designed. Forty children aged between 4 and 15 years, ASA I-II, scheduled for elective tonsillectomy and/or adenoidectomy were randomized into two groups. For patients in Group T (n = 20) swabs soaked with 2 mg/kg tramadol diluted in 10 ml saline were applied to both of their tonsillar fossa for 5 min; in the control group (n = 20) swabs soaked with 10 ml saline were applied. Postoperative pain scores, bleeding, nausea, vomiting, abdominal discomfort, constipation, pain in the throat, painful swallowing, fever, otalgia, trismus, and halitosis were recorded at the first, fifth, thirteenth, seventeenth, twenty-first, and twenty-fourth postoperative hours and the week after tonsillectomy. RESULTS: Pain scores were found to be significantly lower at the 21st hour and on postoperative day seven in the tramadol group compared with the control group (p < 0.05). Mean daily pain scores ranged from Day 1: 0.34 (±0.21) to Day 7: 0.11 (±0.08) in the tramadol group and Day 1: 0.53 (±0.14) to Day 7: 0.42 (±0.15) in the control group. There were no significant differences in morbidity between the groups (p > 0.05). CONCLUSION: Topical 5% tramadol with its local anesthetic effect seems to be an easy, safe, and comfortable approach for pain management in children undergoing tonsillectomy.

Auditory evaluation in Parkinsonian patients.

Twenty Parkinson's disease (PD) patients (mean age 69.9 years) and 24 normal individuals' (mean age 63.8) both ears were investigated by brainstem auditory evoked potentials (BAEPs) and pure tone audiometry (PTA). There were no statistically significant age differences between the patients and control subjects. PTA results were significantly elevated for PD patients in 4,000 and 8,000 Hz (P < 0.05). Parkinsonian patients showed significantly increased latencies in wave V and I-V interpeak latencies (P < 0.05). The results of this study suggest that PTA and BAEPs could be affected in parkinson disease.

Vasoconstriction and analgesic efficacy of locally infiltrated levobupivacaine for nasal surgery.

BACKGROUND: In this study, we compared the use of preincisional lidocaine 2% with epinephrine (LA) and levobupivacaine 0.25% plain (LB) for postoperative analgesia and vasoconstriction in patients undergoing nasal surgery. METHODS: Sixty patients were randomly assigned to receive preincisional local infiltration under general anesthesia. Group LB received levobupivacaine 0.25%, and group LA received epinephrine plus lidocaine 2% (add volume injected). Intraoperative hemodynamic changes, pre- and postoperative hemoglobin and hematocrit values were recorded. Visual analog scale values 30 min and 1, 2, 8, 12, and 24 h postoperatively and the need for rescue analgesic treatment in the first 24 h of all patients was recorded. RESULTS: At 30 min and 1, 2, 8, and 12 h postoperatively, visual analog scale values were lower in group LB than in group LA (P < 0.0001, P = 0.002, P = 0.023, P < 0.0001, and P = 0.011, respectively). The analgesic requirement was significantly lower in group LB when compared with that in group LA (P = 0.038). Group LB had significant differences between preoperative and postoperative hemoglobin and hematocrit values (P = 0.014 and 0.025). Group LA had significant differences between preoperative and postoperative hemoglobin and hematocrit values (P = 0.031 and 0.024). CONCLUSIONS: We conclude that postoperative analgesia in nasal surgery with local infiltration of levobupivacaine was significantly more potent and longer lasting than that achieved by lidocaine plus epinephrine.

Does topical ropivacaine reduce the post-tonsillectomy morbidity in pediatric patients?

OBJECTIVES: To determine whether post-operative administration of topical ropivacaine hydrochloride decreases morbidity following adenotonsillectomy. STUDY DESIGN: Prospective, randomized, double-blind clinical trial. SETTING: University referral center; ENT Department. PARTICIPANTS: Fourty one children, aged 4-16 years, undergoing tonsillectomy. METHODS: Patients received 1.0% ropivacaine hydrochloride soaked swabs packed in their tonsillar fossae while the control group received saline-soaked swabs. Mc Grath's face scale was used to compare the two groups in respect of pain control. Chi-square and two-tailed unpaired Student's t-tests or Mann-Whitney-U-tests were used to compare the two independent groups. As 10 we made 11 comparison between groups, for Bonferroni correction, p<0.005 was accepted as statistically significant. RESULTS: Only first hour there was no significant pain-relieving effect seen in the ropivacaine group (p>0.05). The other hours and days there were statistically significance between the two groups (p<0.001). Also, the other post-operative parameters such as nausea, fever, vomiting, odor, bleeding, otalgia and trismus were not statistically different between the two groups. There were no complications associated with ropivacaine hydrochloride. No patients in this study suffered systemic side effects related to the use of this medication. CONCLUSION: Locally 1.0% ropivacaine administration significantly relieves the pain of pediatric tonsillectomy and, it is a safe and effective method. High concentrations of ropivaciane may produce clinically significant pain relief. It is more effective to reduce of post-operative analgesic requirement after first hour.

Effects of desflurane on middle ear pressure.

OBJECTIVE: To evaluate the effects of desflurane on middle ear pressure. STUDY DESIGN: A prospective clinical study. METHODS: In this study, 38 ears of 19 male children that were scheduled for circumcision were included. Baseline tympanometry reading was performed on each ear just before anesthesia. After induction anesthesia with propofol a laryngeal mask was applied and desflurane administration was started. The next tympanometry reading was taken at 5th, 10th and 15th minute after administration and at the 10th minute after the cessation of desflurane. Data were analysed using Wilcoxon test. RESULTS: Mean MEP values before anesthesia in 38 ears of 19 boys were -10.32+/-33.14. After starting the administration of desflurane 5th minute mean value was 71.15+/-60.42, at the 10 th minute 111.56+/-59.03 and at the 15th minute it increased to 120.50+/-54.14, and these measurements were significantly higher than the starting value (p<0.001). After cessation of desflurane mean MEP value dropped to 57.56+/-79.06, but compared with the starting value this was also significantly higher (p<0.001). CONCLUSION: Desflurane may increase the middle ear pressure and it may be unsuitable for certain middle ear surgeries.

Differences of the Voice Parameters Between the Population of Different Hearing Tresholds: Findings by Using the Multi-Dimensional Voice Program.

OBJECTIVES: To compare voice parameters in subjects with different hearing level. METHODS: The evaluation consisted of Multi-Dimensional Voice Program (MDVP) and electroglottography. Group 1 consisted of normal hearing subjects which is bilateral average hearing better than 25 decibels (dB) whereas group 2 consisted of patients who have bilateral average hearing between the 25 and 60 dB and group 3 consisted of patients who have bilateral average hearing between the 60 and 90 dB. The evaluations were performed on males and females separately. RESULTS: In female subjects, fundamental frequency (F0), absolute jitter, %jitter and soft phonation index (SPI) were significantly different between the group 1 and group 2. Also, we detected significant difference on maximum phonation time (MPT), fundamental frequency, absolute jitter and %jitter, and variable F0 (vF0) values between group 1 and group 3. Male subjects demonstrated significant difference between the group 1 and group 2 in MPT, absolute jitter, %jitter, vF0, and SPI parameters. Between the group 3 and group 1; differences in absolute jitter, %jitter, shimmer, %shimmer, vF0, and SPI were also significant. CONCLUSION: This study concluded that even mild to moderate hearing losses may affect voice patterns in adults and also females and males react differently to hearing loss in some parameters.

Hemimacroglossia caused by isolated plexiform neurofibroma: a case report.

OBJECTIVES: The present case is a diffuse isolated plexiform neurofibroma of the tongue that was not associated with neurofibromatosis that we treated with intraoral surgery. STUDY DESIGN: A case report. METHODS: We present a 5-year-old girl with isolated plexiform neurofibroma of the tongue with infiltration of the tongue base and review treatment approaches for this very rare tumor. RESULTS: An intraoral approach appears to be a good alternative method that allows both an acceptable exposure for total excision and limited postoperative sequelae. CONCLUSIONS: Isolated plexiform neurofibroma of the tongue is very rare. It causes a massive macroglossia that is progressive with advance of years and disturbs the patient's speech, occlusion, and tongue movements. Involvement of the tongue may be associated with infiltration into the deep structures of the neck by the tumor, thereby presenting considerable operative difficulties.

Effects of sevoflurane and TIVA with propofol on middle ear pressure.

OBJECTIVE: To evaluate the effects of sevoflurane and TIVA with propofol on middle ear pressure and to show the importance of anesthesia without using any inhalational agents during middle ear surgery. STUDY DESIGN: A prospective, randomized controlled clinical study. METHODS: In this study, 25 male children that were scheduled for circumcision were randomised into two groups. Group I (n=13) received TIVA with propofol and group II (n=12) received sevoflurane. Baseline tympanometry reading was performed on each ear just before anesthesia. The next tympanometry reading was taken 10min after applying the laryngeal mask. Data were analysed by Mann-Whitney U (between groups) and Wilcoxon tests (within groups). RESULTS: Mean MEP values in 26 ears of 13 boys in group I did not show any significant difference before and after the anesthesia with propofol (p>0.05). In group II mean MEP values in 24 ears of 12 boys showed a significant increase after the anesthesia with sevoflurane (p<0.001). No significant difference was found between the MEP values of the two groups before the anesthesia (p>0.05), and MEP values measured during the anesthesia were significantly higher in group II (p=0.007). CONCLUSION: Sevoflurane may increase the middle ear pressure and TIVA with propofol may be used in middle ear operations more safely than sevoflurane.

Isolated middle ear meningioma.

Meningiomas are slowly progressive, benign tumors that originate from meningothelial cells. Extracranial meningiomas, especially isolated middle ear meningiomas, are very rare. In this article, we report a rare secretory type primary middle ear meningioma which was histopathologically confirmed in a 46-year-old female patient who presented with otological and neurootological symptoms.

Branchio-oculo-facial syndrome with the atresia of external ear.

We report an 8-year-old child with branchio-oculo-facial syndrome. He showed atresia of external ear, preauricular pit, maxillar and mandibular hypoplasia, mild ptosis on the left side, lacrimal duct obstruction, unilateral branchial cyst, hypertrichosis of the neck, left foot showed mild syndactily of fourth and fifth toes and dental abnormalities. His mother had pseudocleft of the lip which led to the diagnosis. The importance of serial observations in patients with rare genetic disorders is emphasized.

Measuring the correlation between adenoidal-nasopharyngeal ratio (AN ratio) and tympanogram in children.

OBJECTIVE: To evaluate the correlation between adenoidal-nasopharyngeal ratio (AN ratio) and tympanogram in children. STUDY DESIGN: A prospective clinical study from June 2002 to May 2003. METHOD: A total of 64 children, aged 6-9 years who presented with nasal obstruction, snoring, mouth breathing, and hyponasal speech were examined and AN ratio was calculated by using the lateral neck radiograms and compared with the tympanometric values. The relationship between AN ratio and middle-ear pressure was evaluated, regarding the AN ratio of 0.71. The chi-square test was used to analyze the correlation between AN ratio and middle ear pressures and Wilcoxon test was used to compare the changes between the mean AN ratio values, and mean middle ear pressures (including A and C type tympanograms) before and after medical therapy. RESULTS: Middle-ear effusions and C type tympanograms in impedance audiometry were both related to eustachian tube dysfunction resulting from enlargement of the adenoids with AN ratios higher than 0.71. Middle ear pressures were found lower in children with AN ratio greater than 0.71 than in children AN ratio less than 0.71 and the difference was highly significant (p<0.001). Although medical treatment of large adenoids was rather effective to shrink the adenoid tissue (p<0.001), it did not cause a statistically significant change in tympanometric values (p>0.05). CONCLUSIONS: Antibiotherapy is effective in reducing adenoid size without signs and symptoms of infection. The reduction of the adenoids in size after 3 weeks of antibiotherapy has an positive effect on recovery of eustachian tube function but is not sufficient in patients with middle ear effusion. Early ventilation tube insertion may be an alternative therapy for the middle ear effusions not improving by 3 weeks medical therapy.

Evaluation of deaf children in a large series in Turkey.

OBJECTIVE: Evaluation of the deafness etiology, ear examination findings and hearing levels of deaf children in a large series. PATIENTS AND METHODS: We studied 840 deaf primary school children (486 male, 354 female, mean age 12.69+/-3.52, range 5-22). A questionaire investigating the prenatal, perinatal and postnatal etiological causes was prepared and pedigree analysis was performed. After ENT examination, odyologic tests were performed. RESULTS: The etiological features of deafness were found for genetic causes as 429 cases (51.1%), 127 children (15.1%) for acquired group and 284 children (33.8%) for unknown group. We confirmed 136 (15.5%) syndromic deaf children and 19 of them (13.9%) were autosomal recessive (AR), 105 of them (77.2%) were autosomal dominant (AD), six (4.4%) of them were X-linked. Two hundred and ninety-three deaf (33.4%) children were in the familial nonsyndromic group. In this group, the inheritance of 255 (87%) were AR, 23 (7.8%) were AD and 15 (5.2%) were X-linked recessive. Febrile convulsion was identified as the most common etiology in 36 (4.3%) cases in the acquired group. Three hundred and twenty-two (67.7%) children had profound HL (above 91 dB), 111 (23.3%) had severe HL and 43 (9%) had moderately severe HL. Sensorineural HL was found in 439 (92.2%) and mixed type hearing loss was seen 37 (7.8%) of 476 cases. We found many major and minor abnormalities and ocular, ear and dental pathologies. The prevalence of ear diseases was found in 203 (24.2%) of children. Impacted wax was found in 80 (9.5%) of 840 children with otoscopic examination and was the most common pathology, retraction in 70 (8.3%) and perforation in 15 (1.8%) followed it. CONCLUSION: Preventable ear disease are important health problems among school children for the deaf because these diseases can affect the real level and type of deafness, so determining early diagnostic criteria, ear diseases and minor abnormalities is important for early rehabilitation. Syndromes can be prevented in pregnancy, infections can be prevented in prenatal or postnatal period but unknown group cannot be prevented although the unknown etiology can be reduced by multidiciplinary approach.

Laryngocele in association with ankylosing spondylitis.

A laryngocele is a cystic dilatation of the laryngeal saccule. The etiology of laryngoceles is unclear, but congenital and acquired factors are considered to play a role in their development. An acquired laryngocele may develop when the laryngeal ventricle becomes functionally obstructed as a result of an increase in intraglottic pressure, such as that caused by excessive coughing, playing a wind instrument, glass blowing or obstruction of appendicular ostium. We present a case of laryngocele in a patient with ankylosing spondylitis. To the authors' knowledge, and from a review of the literature, this combination has not been previously described. The laryngocele was also infected in this case. We believe that development of the laryngocele might be a result of increased intra-abdominal pressure, caused by rheumatoid arthritis, with associated increased intralaryngeal pressure.

Bone induction capacity of the periosteum and neonatal dura in the setting of the rat zygomatic arch fracture model.

OBJECTIVES: Osteogenic properties of the dura and periosteum are thought to contribute to the regenerative capacity of membranous bone tissue. The purpose of this investigation was to elucidate (1) whether dura without underlying neural tissues can induce osteogenesis, (2) to what extent the periosteum participates in membranous bone healing, and (3) the difference between dura-induced and periosteum-induced osteogenesis. METHODS: A standardized 2-mm defect was created within the middle portion of each zygomatic arch in 30 Wistar albino rats. The rats were divided into 3 groups, 10 animals in each group. In group 1, the periosteum was removed and neonatal dura grafts were transplanted onto the zygomatic arch bone defect circumferentially. In group 2, the overlying periosteum was preserved. In group 3, the periosteum was removed. At 3 and 10 weeks, animals from each group were killed, and specimens were obtained. Data were collected from the 3-dimensional computed tomographic scans and histologic studies to compare the extent of bony repair. RESULTS: Fracture sites demonstrated osteogenesis associated with chondrogenesis in groups 1 and 2 and only limited osteogenesis with no chondrogenesis in group 3. In some animals in group 3, cortical bone ends underwent resorption. In groups 1 and 2, bone defects were obliterated by the formation of the mature compact bone at 10 weeks postoperatively. The difference between bone regeneration in these groups was not significant (P =.16). In group 3, the defects failed to heal by bony union, and in most of the samples the fibrous union was observed instead. The difference between groups 1 and 3 was significant (P =.03). The difference between groups 2 and 3 was not significant (P =.09). CONCLUSIONS: The trend toward significance is in agreement with the current clinical practice of preserving periosteum in the manipulations of the membranous bone defects. Newborn dura can exert a potentiating effect on osteogenesis.
