Evaluation and Management of Antrochoanal Polyps

Huseyin Yaman; Suleyman Yilmaz; Elif Karali; Ender Guclu; Ozcan Ozturk

Antrochoanal polyps (ACPs) are benign polypoid lesions arising from the maxillary antrum and they extend into the choana. They occur more commonly in children and young adults, and they are almost always unilateral. The etiopathogenesis of ACPs is not clear. Nasal obstruction and nasal drainage are the most common presenting symptoms. The differential diagnosis should include the causes of unilateral nasal obstruction. Nasal endoscopy and computed tomography scans are the main diagnostic techniques, and the treatment of ACPs is always surgical. Functional endoscopic sinus surgery (FESS) and powered instrumentation during FESS for complete removal of ACPs are extremely safe and effective procedures. Physicians should focus on detecting the exact origin and extent of the polyp to prevent recurrence.

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.

Ender Guclu; Fatih Oghan; Ozcan Ozturk; Murat Alper; Erol Egeli

Oncocytic carcinomas are uncommon; they represent 11% of all oncocytic salivary gland neoplasms, 0.5% of all epithelial salivary gland malignancies and 0.18% of all epithelial salivary gland tumors. A 65-year-old woman was admitted to our ENT clinic with a history of a painless left preauricular mass. No lymph node was palpable on either side of her neck. Computed tomography demonstrated a 3×3-cm solid lesion in the left parotid gland. As oncocytes and atypical cells were seen at the cytologic examination of a fine-needle aspiration biopsy, this finding suggested a malignant epithelial tumor. Total parotidectomy by preserving the facial nerve was performed. The result of the pathologic examination was oncocytic carcinoma regarding histopathologic and immunohistochemical findings and especially the invasive growth pattern. We preferred a close follow-up to an elective neck dissection, and reserved the neck dissection for a recurrence. The prognosis of oncocytic carcinomas is not well known because of their low incidence. Further investigation of the prognosis of patients with oncocytic carcinoma of the parotid gland is warranted as more cases are reported.

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 Graths face scale was used to compare the two groups in respect of pain control. Chi-square and two-tailed unpaired Students 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.

OBJECTIVE To reduce the post-tonsillectomy morbidity by swab soaked with 5 ml levobupivacaine hydroclorur (25 mg/10 ml). STUDY DESIGN A double-blind prospective randomized controlled clinical study. METHODS In this randomized double-blind study in group I (30 children, mean age 7.5+/-2.6) we tightly packed swab soaked with 5 ml levobupivacaine hydroclorur (25mg/10 ml) and in group II (21 children, mean age 7.9+/-3.7) we used 5 ml saline swabs into each of the two tonsillar fossae after tonsillectomy for 5 min. We used McGraths face scale to compare the two groups in respect of pain control. RESULTS There was statistically significant pain relieving effect in the levobupivacaine group in the first 24h (p<0.05). But after 24h pain relieving effect of levobupivacaine was not significant (p>0.05). We did not see any serious complications for both groups. Postoperative morbidity mean results (nausea, vomiting, fever, bleeding, halitosis and ear pain) were not statistically different between the two groups (p>0.05). CONCLUSION Topical levobupivacaine seems to be a safe and easy medication for postoperative pain control in pediatric tonsillectomy patients.

OBJECTIVE The incidence rate of recurrence of otitis media with effusion (OME) in children after tympanostomy tube extrusion and the relationship between recurrence and tube retention time was investigated. Also relationship between recurrence rate and initial age of tube insertion was analysed. STUDY DESIGN A retrospective case series of patients who had tympanostomy tube insertion. METHODS A total of 91 children (169 ears) were reviewed. Ears of children divided into three groups according to retention time of tympanostomy tubes. Group I: tympanostomy tube retention time less than 6 months. Group II: tympanostomy tube retention time 6 months to 12 months. Group III: tympanostomy tube retention time 12 months or more. RESULTS OME recurrence rate after tube extrusion was 20.7% in the study. The longer the tympanostomy tube retention time was the lower was the recurrence rate of OME. The comparison of the three groups indicated that recurrence rates were higher in group I (36.54%), than in group II (17.74%) and in group III (9.1%). There were statistically significant differences in recurrence rates between group I and group III, and between group I and II (p<0.05, p<0.05). However, the difference in recurrence rates between group II and group III was statistically not significant (p>0.05). In the preschool age group and school age group, the recurrence rates were 5.5% and 15.4%, respectively. There was no significant difference between these two groups (p>0.05). OME recurrence was observed in 9.9% of males and in 11% of females. There was no significant difference in recurrence rates between males and females (p>0.05). CONCLUSION After extrusion of tympanostomy tube, children should be followed-up regularly for recurrence of OME. The shorter the retention time of tympanostomy tubes was the higher was the recurrence rate. For the treatment of OME the ideal type of tubes should have the lowest complication and recurrence rates. Further studies are needed to ascertain the relationship between the incidence of OME and optimal tympanostomy tubes duration of tube stay in tympanic membrane. Therefore, new studies with larger series are necessary to investigate the correlation between the recurrence rates and different tympanostomy tubes after extrusion of tubes.

OBJECTIVE To determine relationship between myringosclerosis and tube retention time and sex in children with chronic otitis media with effusion who were treated with tympanostomy tube insertion. Also, the relationship between myringosclerosis both sex and initial age of tube insertion were investigated. METHODS A total of 101 children (195 ears) were reviewed. Ears were divided into four groups according to retention time of tympanostomy tubes. Group I: Retention time of tympanostomy tube less than 6 months. Group II: Retention time of tympanostomy tube from 6 months to 12 months. Group III: Retention time of tympanostomy tube of 12 months or more. Group IV: Myringotomy group without tympanostomy tube insertion. RESULTS The order of the myringosclerosis rates were as follows from the highest to lowest one; group III (44.1%), group II (42.4%), group I (14.3%), and group IV (7.7%). Myringosclerosis was more common in group I compared with group IV, but the difference was statistically not significant (p>0.05). There were no statistically significant differences in myringosclerosis rates between the group II and group III (p>0.05). On the other hand, statistically significant differences were observed in myringosclerosis rates between group I and group II (p<0.05), and between group I and group III (p<0.05); also similar significant differences were present in myringosclerosis rates between group IV and group II (p<0.05), and between group IV and group III (p<0.05). There was no significant difference between preschool age group and school age group. Myringosclerosis was observed in 40% of boys and in 51.2% of girls. CONCLUSION Myringosclerosis is frequent in patients who underwent tympanostomy tube insertion. The frequency of myringosclerosis is much higher in tympanic membranes with tympanostomy tube insertion than tympanic membranes with myringotomy, and the location of sclerotic plaques does not always correspond to the tympanostomy area. The myringosclerosis rate was increased when the tympanostomy tubes stay on tympanic membrane for a long time. Highest myringosclerosis rates were observed if the extrusion time was 12 months or longer. In our analysis, sex and initial age of tube insertion were not significant factors for the development of myringosclerosis after extrusion of tympanostomy tubes.

When should automatic Auditory Brainstem Response test be used for newborn hearing screening

İlhan Ünlü; Ender Guclu; Huseyin Yaman

OBJECTIVES The aim of this study was to investigate the referral rate and when automatic Auditory Brainstem Response (aABR) should be used for newborn hearing screening. METHODS The present study enrolled 2933 healthy full-term infants and 176 infants with perinatal risk factors. Hearing screening using Transient Evoked Otoacoustic Emissions (TEOAEs) was performed in newborns for the first time 5 days after birth except perinatal risk factors infants. The TEOAE was repeated to neonates failing to pass at the 15th day after birth. Neonates failing to pass the second TEOAE, repeated the test again at the 30th day after birth. Neonates failing to pass the third TEOAE were referred for the second stage screening using aABR. In addition, neonates with risk factors were tested with aABR directly. RESULTS In this research, 85 (2.9%) infants who could not pass the TEOAE and 176 infants exposed to perinatal risk factors, underwent the aABR test. In the aABR, 14 (7.9%) of 176 infants exposed to perinatal risk factors and 10 (11.7%) of 85 infants who could not pass the TEOAE failed to pass. As a result, hearing loss was detected in only 10 (0.34%) of 2933 healthy full-term infants. CONCLUSION TEOAE should be performed at least twice in healthy full-term infants before aABR, because aABR is to be performed by specially trained personnel and takes a long time. In view of these results, it is our opinion that infants without perinatal risk factors should undergo TEOAE screening test and infants who did not pass control screening tests and have perinatal risk factors should absolutely undergo aABR test. But it should be remembered that TEOAE can cause a problem to miss auditory neuropathy in infants without perinatal risk factors.

Objective The aim of this study was to find out the efficacy of a polyvinyl alcohol (PVA) sponge (Merocel Kennedy; Medtronic Xomed, Jacksonville, Florida) sinus pack soaked with levobupivacaine hydrochloride to control postoperative pain and analgesic need following functional endoscopic sinus surgery (FESS). Study Design The study was designed as a prospective, double-blind, randomized, controlled study. Forty-one patients who underwent FESS were included in the analysis. Setting A tertiary referral hospital in Turkey. Materials and Methods Patients who underwent FESS were divided into 2 groups. The PVA sponge sinus packs were soaked with 5 mL of levobupivacaine hydrochloride (chirocaine 25 mg/10 mL; Abbott, Nycomed Pharma AS, Elverum, Norway) in group I and with 5 mL of saline in group II. Main Outcome Measures Postoperative pain levels were recorded using a visual analog scale (VAS score, 0-100) at 30 minutes and 1, 2, 8, 12, and 24 hours. Results There were no statistically significant differences between groups regarding age, sex, and American Society of Anesthesiologists status. Postoperative VAS values at 30 minutes and 1, 2, 8, 12, and 24 hours were significantly lower in group I than in group II (P < .05). Supplemental analgesia amount was significantly lower in group I than in group II (P = .003). Conclusion Using levobupivacaine-soaked PVA sponge sinus packs after FESS is an effective, easy, and quick method to control postoperative pain, and it improves patient comfort and tolerability.
