Pediatric Epistaxis-Effectiveness of Conservative Management.

OBJECTIVES: Epistaxis is an emergency medical condition that sometimes requires admission to the emergency department. Pediatric epistaxis differs from epistaxis in the older population in terms of etiology, severity, and management. Our objective was to identify the distinctive features of pediatric epistaxis and determine the appropriate management. METHODS: This was a retrospective study of 231 medical records of children (<18 years old) with epistaxis of a total of 1171 cases in the general population who presented to our medical center's emergency department between 2013 and 2018. RESULTS: Among 231 admissions, 10 children (4.3%) presented more than once. Male patients accounted for the majority of cases (64.5%), and the average age was 9.4 years. Two children were treated with aspirin because of cardiac valve disease. Anterior bleeding was detected in 101 cases (43.7%), whereas posterior origin was observed in 8 cases (3.5%). In 122 cases (52.8%), there was no active bleeding observed. Nose injury was the cause of epistaxis in 24 cases (10.4%), and 16 admissions (6.9%) followed nasal surgical interventions. Nineteen children (8%) had abnormal coagulation tests, and 7 patients (3%) received blood transfusions. Chemical cauterization was performed in 89 cases (39.3%), and anterior packing was needed in only 9 cases (3.9%). Nine children required hospitalization (3.9%), and 2 needed surgical intervention to control bleeding. Compared with the adult population, there were significantly fewer cases of active bleeding, recurrent epistaxis, anterior packing, or need for hospitalization in the pediatric population. CONCLUSIONS: Epistaxis is significantly less severe in the pediatric population, with only a few cases requiring major intervention. Endoscopic examination of the entire nasal cavity and routine coagulation tests are not mandatory unless there is a history of recurrent epistaxis, known coagulopathy, antiplatelet/anticoagulation therapy, or a suspicion of juvenile idiopathic angiofibroma. We suggest using absorbable packs, which offer advantages over cauterization or nonabsorbable packs.

[AUDITORY BRAINSTEM IMPLANTS (ABI) IN CHILDREN: CASE SERIES IN SHAARE ZEDEK MEDICAL CENTER].

BACKGROUND: Cochlear implants (CI) are the treatment of choice for individuals with severe to profound sensorineural hearing loss. A small group of patients, with pathology central to the cochlea, cannot benefit from CI. Examples in children include absence of the cochlear-nerve or cochlear aplasia. In these cases, implantation of an auditory brainstem implant (ABI), directly stimulating the cochlear nucleus, bypassing the inner-ear and auditory-nerve, may be beneficial. OBJECTIVES: Describe a series of children with ABI's treated in Shaare-Zedek, including the first ABI implantation in Israel (2017). METHODS: Of 9 patients with ABI's treated in Shaare Zedek Medical Center ,7 were children implanted between ages 2-8.6 years. Five boys and two girls. Surgeries were conducted in collaboration between neurosurgeons, neurotologists and audiologists (five implanted in Shaare-Zedek and two in New-York University). Follow-up was between 2-6 years. Hearing evaluation was conducted, mainly, with audiograms, categories of auditory performance (CAP), speech perception testing when possible and estimation of device use per day. RESULTS: Six of the seven children, who initially underwent unsuccessful CI, had deficient auditory-nerves. One child had cochlear-aplasia. In 3 children hearing loss was part of the CHARGE syndrome. CAP scores ranged from 0-7 (0,1,3,5,5,7). One child was able to achieve open-set speech perception. CONCLUSIONS: Although functional auditory outcomes for children with ABI are inferior to CI recipients and are highly variable, some children were able to obtain significant benefit. In these children, who are not candidates for CI, the ABI presents the only chance for auditory awareness and may be recommended. DISCUSSION: John Thomas Roland is a consultant and recipient of research support from Cochlear Americas.

The management of acute supraglottitis patients at the intensive care unit.

INTRODUCTION: Acute supraglottitis is a potentially life-threatening condition that often necessitates intensive care unit (ICU) admission for airway monitoring. The objective of this study was to identify clinical criteria that predict a benign course for patients with acute supraglottitis. METHODS: A prospective observational study was performed. Adult patients hospitalized in the ICU between 2007 and 2019 diagnosed with acute supraglottitis were included. All patients were treated with antibiotics and corticosteroids. Fiber optic laryngoscopy (FOL) was performed every 12 h, with each exam defined as "improving", "no change" or "deteriorating" based on the presence of airway edema. Need for airway intervention was correlated to changes in the FOL exam. RESULTS: Of 146 patients included, 14 (10%) required intubation, ten on admission, and four during the first 6 h of ICU admission. FOL follow-up was performed on 528 occasions-427 (81%) exams showed improvement, 16 (3%) deterioration, and 85 (16%) with no change. On no occasions was improvement in FOL followed by deterioration. The median ICU length of stay was 3 (IQR 2-3.5) vs. 1 (IQR 1.0-1.25) day for patients who did or did not require intubation (p < 0.001), respectively. CONCLUSION: Improvement in FOL exam accurately predicted the absence of need for intubation and might represent a criterion for early ICU discharge.

Starplasty tracheostomy: case series and literature review.

OBJECTIVES: The starplasty tracheostomy (SPT) technique has been suggested to reduce the short-term complications of tracheostomy, including accidental decannulation and pneumothorax. The aim of the present study was to conduct a review of key parameters prior to and following treatment of neonates and children with the SPT technique, including indications, complications, perioperative department stay, and overall length of stay in one University-Affiliated Medical Center. METHODS: A retrospective chart review of all children under the age of 18 underwent SPT in a single center between February 2006 and January 2012. RESULTS: Among the 39 patients reviewed, the median age at the time of surgery was 14.5 months, ranging from 3 days to 8.8 years. The most common indication for SPT was respiratory insufficiency resulting from central nervous system disorders (15, 38.4%) followed by neuromuscular disorders (14, 35.9%). Ten (25.6%) operations were performed on neonatal intensive care unit (NICU) patients and 29 (74.4%) on pediatric intensive care unit (PICU) patients. The median postoperative hospital stay was 19.5 days (range of 3-207 days); however, the median postoperative stay in the PICU was 13.5 days. There were no decannulations or any other short-term complications after SPT, and no SPT-related deaths occurred. CONCLUSIONS: In our series, pediatric SPT was not associated with any major complications. Therefore, we conclude that SPT should be considered as a safe and advantageous alternative for traditional tracheotomy, especially in patients with low probability of future decannulation, and, therefore, at low risk of a persistent tracheocutaneous fistula.

Is Needle Aspiration for Peritonsillar Abscess Still as Good as We Think? A Long-term Follow-up.

OBJECTIVE: The aim was to study the therapeutic management, recurrence, and need for tonsillectomy in patients who underwent needle aspiration for peritonsillar abscess (PTA). METHODS: A prospective observational design study was performed. Patients hospitalized in Shaare Zedek Medical Center between the years 2004 and 2007 with a diagnosis of PTA who underwent needle aspiration obtaining pus were included. A minimum 5-year follow-up was required for all patients. Recurrences, complications, the need for a repeated surgical procedure, length of hospital admission, and tonsillectomy were the primary end points. RESULTS: The study included 117 patients. One hundred four patients (88.9%) improved after 1 needle aspiration without any other intervention, whereas 13 patients (11.1%) required an additional procedure. Broad spectrum antibiotics showed a statistical advantage over penicillin only, regarding need for recurrent procedure (14.7% vs 4.7%, P = .02). No short- or long-term complications were documented. Seventeen patients (14.5%) had any recurrence. Primary recurrent tonsillitis, female sex, and younger age were predictive risk factors for recurrent events of PTA (32% vs 10%, P < .01). A total of 18 patients (15.4%) eventually underwent tonsillectomy. CONCLUSION: Needle aspiration is an effective first line procedure for patients with PTA. Tonsillectomy is not necessary in most cases. In our study, young age, female sex, and recurrent tonsillitis are negative prognostic factors for recurrence. These patients should be managed accordingly. Broad spectrum antibiotics may offer additional advantages when compared to penicillin only.

Harmonic scalpel assisted superficial parotidectomy.

OBJECTIVE: The Harmonic Scalpel (HS) has been recently widely used to perform a variety of surgical procedures. We reviewed our experience with the use of HS in superficial parotidectomy to determine the safety and efficacy of this procedure, with regard to operative time, postoperative facial nerve function, and drainage output. STUDY DESIGN: Nonrandomized retrospective review. MATERIALS AND METHODS: The medical records of all patients who underwent superficial parotidectomy for benign pathology at Shaare Zedek Medical Center from January 2006 to July 2009 were retrospectively reviewed. Patients with prior facial nerve weakness or prior parotid surgery or who had undergone concurrent neck dissection or total parotidectomy were excluded. RESULTS: Fifty-eight patients were reviewed; 26 patients underwent HS parotidectomy and 32 patients underwent conventional (cold knife) parotidectomy (control group). Harmonic Scalpel assisted parotidectomy was associated with significantly decreased length of surgery from 163.12 ± 21.8 minutes for controls to 137.3 ± 18.6 minutes in the HS assisted group (P < .05). The incidence of temporary postoperative facial nerve paresis was significantly reduced from 43% in the controls to 23% in the HS group (P < .05). No permanent facial nerve paralysis was reported. There were differences in the overall postoperative drain output between the HS and control groups, 68 ± 22.3 mL and 73.5 ± 38.2 mL, respectively, but these differences did not achieve significance. CONCLUSION: This study shows that HS assisted superficial parotidectomy for benign pathology is a safe technique and associated with reduced surgical time and incidence of temporary postoperative facial nerve paresis compared with conventional techniques.

[Fluoroscopic assisted cochlear implantation in children with inner ear malformations].

BACKGROUND: Cochlear implants are the treatment of choice for individuals with severe to profound sensorineural hearing loss. In most cases, the anatomy is normal and the insertion of the electrode-array is straightforward, complete and in the correct position. In the presence of inner-ear malformations, the risk of an intra or extra-cochlear malpositioned electrode-array increases. OBJECTIVES: To describe the technique of fluoroscopic assisted cochlear implantation in children with severe inner-ear malformations and present the results with respect to the number of active electrodes and function. METHODS: Fifteen fluoroscopy assisted implantations in 9 children were conducted at the Shaare Zedek Cochlear Implant Center between 2009-1014. All implanted ears had severe anatomic malformations. Mean implantation age was 3.5 years (range 1-11). Six children underwent sequential bilateral implantation. Two children underwent revision surgery due to a malpositioned electrode initially implanted without fluoroscopy at other centers. RESULTS: There was no radiologic or electro-physiologic evidence of kinking, bending or electrode damage in all 15 implantations. Complete insertion was achieved in all ears except one with partial insertion. There were no extra-cochlear or intrameatal placements. In 9 ears, all electrodes were active at switch-on and in the remaining, 15-20 were active. In all ears the Ling-6 sounds were detected and in 13 they were also identified. CONCLUSION: Fluoroscopy is an effective tool in complex cochlear implant surgeries and its use is simple and safe. As demonstrated in this study, with fluoroscopy assistance, good results are achieved in children with inner-ear malformations.

Comparison of postoperative bleeding in pediatric tonsillectomy versus tonsillotomy.

OBJECTIVE: Tonsillar surgery is a common intervention for pediatric obstructive sleep apnea and recurrent tonsillitis. This study compared postoperative bleeding incidence and severity following tonsillotomy and tonsillectomy at a single medical center. STUDY DESIGN: A retrospective cohort study on 1984 pediatric patients (1-18 years old) who underwent surgery during 2004-2011 and 2019-2022. Tonsillectomy was performed during 2004-2011, while tonsillotomy was preferred for obstructive sleep apnea during 2019-2022. Tonsillectomy was performed using cold steel technique with complete removal of tonsillar tissue, while tonsillotomy was conducted using mono- or bipolar diathermy, preserving minimal tissue on the tonsillar capsule. SETTING: Shaare-Zedek Medical Center, Faculty of Medicine, Hebrew University. METHODS: Outcome measures included postoperative bleeding incidence and severity, surgery duration, hospitalization length, and readmission. RESULTS: Tonsillotomy was conducted on 958 (48.3 %) patients, and tonsillectomy was performed on 1026 (51.7 %) patients. Obstructive sleep apnea was the only indication in 1553 (78.3 %) patients. Overall bleeding rate was lower following tonsillotomy (3.9 %) than tonsillectomy (9.5 %) (p < 0.001). Significantly more patients required surgical bleeding control post-tonsillectomy than post-tonsillotomy: 39 (3.7 %) vs. 5 (0.5 %), respectively (p < 0.001). Tonsillectomy resulted in higher readmission rates (11.8 % vs 6.1 %, p < 0.001), more blood transfusions (3 vs. 0), and higher postoperative hemoglobin diminution (1.57 ± 2 vs. 0.94 ± 1 g/dL, p = 0.035). The duration of the surgery was shorter for tonsillotomy (24.7 vs 26.5 min, p = 0.012). Tonsillectomy sustained higher bleeding rates for obstructive sleep apnea patients (7.0 % vs 3.9 %, p = 0.006). For recurrent tonsillitis patients, bleeding rates did not vary between year groups. Older age and tonsillectomy were the most significant risk factors for postoperative bleeding. CONCLUSION: Among children undergoing tonsillar surgery for obstructive sleep apnea, tonsillotomy was associated with a safer postoperative bleeding profile, reduced bleeding severity, and fewer readmissions compared to tonsillectomy.

Conscious sedation for the management of peritonsillar abscess in pediatric patients: A prospective case series and literature review.

OBJECTIVE: Peritonsillar abscess (PTA) is a common pediatric infection requiring drainage. Conscious Sedation (CS) can facilitate drainage in uncooperative children. However, it carries risks, especially if the airway is compromised. Moreover, evidence on its safety and efficacy is limited. This study examined the safety, pain reduction, and anxiety management of hospitalized pediatric patients treated for PTA under CS. MATERIALS AND METHODS: We performed a prospective observational case series of 118 children aged 2-15 years with 155 PTA episodes, managed from 2016 to 2023. Conscious sedation was used in 42 episodes. Outcomes were compared among CS and non-CS (local anesthesia only). Complications assessed safety. Efficacy was evaluated by the amount of pus, hospitalization parameters, pain scores, and recurrence. RESULTS: No significant differences were found regarding the demographic and presentation parameters except for younger age among the CS group (9 vs 11 years p = 0.001). One minor oxygen desaturation (2 %) event occurred with CS. Abscess drainage amount was greater with CS than non-CS, 4.9±4 mL vs. 3.2±2 mL, respectively (p = 0.03). Hospitalization stays were similar among groups. Maximum pain scores were lower with CS than non-CS, 1.4 ± 2 vs 4.2 ± 3 (p < 0.001); similarly, IV pain medication was used less frequently, 0.9 ± 1 vs. 1.6 ± 3 (p = 0.045), and the need for re-aspiration was less common 14 % vs. 28 % (p = 0.04), with CS than non-CS, respectively. The three-month recurrence rate was numerically lower with CS (5 % vs. 14 % non-CS). CONCLUSIONS: Conscious sedation facilitates PTA drainage with excellent safety and improved efficacy compared to local anesthesia in children. Pain scores are reduced both during drainage and hospitalization. Our prospective data add to the limited evidence supporting CS as a viable option for abscess drainage in uncooperative pediatric patients. Further study is warranted to confirm potential long-term reductions in recurrence.

Posisep Versus PureRegen Gel for Post ESS Nasal Packing - A Randomized Blinded Prospective Study.

OBJECTIVE: Endoscopic sinus surgery (ESS) is the procedure of choice for chronic rhinosinusitis (CRS). Adhesions are the most common postoperative complications, causing recurrent disease and revision surgery. Postoperative care is thus essential for the healing of the operated cavity. A wide variety of packing materials are used to prevent bleeding and adhesions postoperatively. Two main absorbable packing materials are used: Foam-based packs (e.g., Posisep and Nasopore) and gel-based packs (PureRegen Gel - PRG). The current study is a randomized, blinded, prospective analysis of cavity healing using Posisep and PRG in ESS, aiming to compare the pros and cons of the two. METHODS: Patients with bilateral symmetric CRS were recruited for the study. At the end of surgery, one side was randomly packed with Posisep, whereas the other was packed with PRG. The postoperative cavity cleaning was video recorded and a blinded physician evaluated the mucosal healing. RESULTS: The side packed with Posisep had significantly less middle turbinate (MT) lateralization and adhesions yet dissolved significantly slower than the PRG, causing more mucosal edema. Severe MT scarring requiring recurrent medialization and adhesiolysis was exclusively observed in the PRG group. All differences were observed in the early postoperative period (up to 12 weeks after surgery). By that time, only the MT position was significantly different between groups, despite recurrent adhesiolysis and medialization. CONCLUSION: The authors recommend using Posisep for MT support only when it is unstable or lateralized. Packing the surgical cavity in other cases with PRG is more beneficial. LEVEL OF EVIDENCE: 2 Laryngoscope, 133:1834-1838, 2023.

Time from sudden sensory neural hearing loss to treatment as a prognostic factor.

Introduction: The widely accepted treatment for sudden sensorineural hearing loss (SSNHL) is corticosteroid treatment (oral or intratympanic). The main goal of this work is to define the significance of the time between symptom onset and treatment initiation, as well as other prognostic factors, for hearing improvement. Methods: This retrospective study included 666 patients treated for SSNHL. Demographic data, audiometry, treatment method, time since symptom onset, and associated symptoms were recorded for each patient. The patients were divided into five groups according to the treatment initiation time-half a week, one week, 2 weeks, 3 weeks, or 4 weeks and over-after symptom onset. The degree of improvement was assessed by comparing the audiometry at the beginning and the end of the treatment. Results: The average period of hearing loss from symptom onset to treatment initiation was 10.8 days. Significant differences were found between the groups of half a week, one week, and 2 weeks and the groups of 3 weeks and 4 weeks and over (each separately, p < 0.001). No difference was found between the half-week, one-week, and two-week groups, nor was there a difference between the three-week and four-week-and-over groups. A correlation was found between the treatment initiation time in days and the degree of improvement in hearing for both speech recognition threshold (SRT) and discrimination, R = 0.26 p < 0.001 and R = 0.17 p < 0.001, respectively. No correlation was found for gender, age of the patients, comorbidities, or associated symptoms. Conclusion: The threshold for treatment initiation time is up to 2 weeks, after which the amplitude of hearing improvement decreases significantly. The other prognostic factors measured were not found to be statistically significant predictors.

Vascular Anomaly in the Fallopian Canal Encountered Unexpectedly During Cochlear Implantation.

A 68-year-old male with progressive sensorineural hearing loss underwent left cochlear implant surgery. While developing the posterior tympanotomy and identifying the facial nerve mastoid segment, gentle stimulation by the nerve stimulator resulted in unexpected profuse venous bleeding. After achieving hemostasis with Surgicel and Spongostan, the posterior tympanotomy was extended exposing a large aberrant vein running parallel to the tympanic and mastoid segments of the facial nerve in the fallopian canal. Good exposure and careful palpation of the vein assisted in ruling out facial nerve hemangioma. An intraoperative decision to proceed with implantation, taking into account limited benefit from future magnetic resonance imaging, was taken. The patient had a temporary 3-month post-operative facial nerve weakness, probably from pressure applied during hemostasis. Auditory cochlear implant function was excellent. A larger than normal diameter of the tympanic and mastoid segments of the facial nerve was seen in re-reviews of the preoperative computed tomography. We believe drawing the readers' attention to this anomaly, which to the best of our knowledge has not been previously described, can assist in the choice of preoperative imaging and increase awareness of deviation from the norm of facial nerve diameter. In addition, knowledge of possible venous anomalies may aid surgeons in such intraoperative decisions.

Shifting trends: mastoiditis from a surgical to a medical disease.

OBJECTIVE: The aim of this study is to review the outcome of pediatric patients suffering from acute mastoiditis treated conservatively and to correlate this to the evolution of our understanding of the shift in which mastoiditis has been transformed from a surgical to a medial disease. METHODS: We performed a retrospective review patient files hospitalized in our tertiary-care center between 2005-2008. We examined the data concerning the infection which included: presenting signs/symptoms, prior otologic history, treatment (including both surgical and conservative) prior to hospitalization and during hospitalization, computed tomography (CT), hospital duration, complications and overall outcome. This data was analyzed and compared between different patients who underwent different treatment strategies. RESULTS: Fifty-one patients were included in this retrospective review. Initially, forty-nine patients admitted to our hospital were treated conservatively. This treatment included intra-venous antibiotics, myringtomy and if needed subperiosteal abscess incision and drainage. Only 2 patients underwent CT scanning on admission. Further on, during hospitalization 4 additional patients underwent CT scanning due to continued fever or progression of local disease. All four CT scans showed no intra-cerebral complications, and so all continued with conservative treatment. CONCLUSION: Most cases of acute mastoidits may be treated with a conservative therapy regime. This regime, in our opinion, should include three branches: the first intravenous antibiotic therapy using a broad spectrum antibiotic. The second is myringotomy and the third branch is incision and drainage of subperiosteal abscess when needed.

Is it Beneficial to Treat Patients Presenting Three Weeks or Longer after the Onset of Sudden Sensorineural Hearing Loss?

OBJECTIVES: The accepted treatment for idiopathic sudden sensorineural hearing loss (ISSNHL) consists of oral or intratympanic steroids. The time from onset to treatment is considered as an important prognostic factor, although there is no clear cutoff point when treatment is no longer beneficial. This study aimed to assess the efficacy of treatment with oral or intratympanic steroids and carbogen, in patients presenting 21 days or later after the onset of hearing loss. MATERIALS AND METHODS: A total of 895 patients with ISSNHL was seen in our center between 2010 and 2018. The study cohort included 103 patients treated with oral or intratympanic steroids or both with carbogen 21 days or longer after experiencing hearing loss. Retrospective analysis of files and audiometry was conducted, and pre- and post-treatment audiograms were compared. Improvement was defined by SRT (≥15 dB improvement), discrimination (≥15% improvement), or 15 dB improvement at specific frequencies (250-500, 4000-6000 Hz). RESULTS: Hearing improvement, according to the study definition, was seen in 22.3% (23/103) of patients within the time period of the treatment. All the 23 patients had functional hearing after treatment and 16 of them returned to their baseline or normal hearing. While the time from onset of ISSNHL to treatment varied, most patients demonstrating improvement were treated 21-30 days after onset. CONCLUSION: In this patient cohort treated late for sudden sensorineural hearing loss (SSNHL), a small but significant number of patients improved during the time of treatment. Although the lack of a control group makes it difficult to prove that the improvement resulted from the treatment, we recommend not to rule out treatment systematically in patients presenting late after ISSNHL. Additional prospective studies are warranted.

Revision cochlear implantation using a double array device in the post-meningitis ossified cochlea.

PURPOSE: To describe the surgical technique and outcome in a series of patients who underwent revision cochlear implantation using a double array or split electrode device. All patients developed ossified cochleae due to meningitis and were functioning poorly with the previous implant. METHODS: Four patients between the ages of 4-15 years underwent revision with five double-array cochlear implant devices. One patient underwent bilateral revision surgery. All patients had previous meningitis with CT and MRI imaging studies that demonstrated completely ossified cochleae. The time interval range between the disease and the initial cochlear implantation and was 4 months to 3 years. The patient's data were retrospectively analyzed with emphasis on the surgical technique, the number of electrodes inserted, and the number of active electrodes at follow-up. In addition, pre and post-revision surgery function was compared. RESULTS: The revision surgery was carried out 2-11 years after the initial surgery. Two tunnels, basal and apical, were drilled in the ossified cochlea. In each of the tunnels, 5 to 11 electrodes were inserted. While the number of active electrodes before revision was 0-5, after revision with the double array, it was increased to 8-12, resulting in improved auditory and speech function. CONCLUSION: Revision cochlear implantation with a double array implant using the two tunnel technique can increase the number of active electrodes. This leads to a better outcome in post-meningitis children with completely ossified cochleae and a poor functioning previous device.

Supraglottoplasty for severe laryngomalacia. Can we predict success?

OBJECTIVES: Laryngomalacia is the dynamic collapse of supraglottic structures during inspiration, leading to a variable degree of airway obstruction. Clinical symptoms appear in the first months of life and are usually mild and resolve by the age of 12-18 months. In severe cases, surgical intervention may be considered. The goal of the study was to review the clinical outcome of pediatric patients who underwent supraglottoplasty for laryngomalacia. MATERIAL AND METHODS: Clinical and demographic data were retrieved from medical records of children diagnosed with laryngomalacia by laryngo-bronchoscopy between 2013 and 2019. Indications, outcome and long-term follow-up were collected from children undergoing surgery. RESULTS: During the study period, 115 children were diagnosed with laryngomalacia. The median age at diagnosis was 3 months. Synchronous airway lesions were diagnosed in 20% of patients. Ten (8.7%) children underwent surgical treatment because of significant respiratory symptoms and/or failure to thrive. Three of them had comorbidities. All otherwise healthy children had significant respiratory and nutritional improvement after surgery while those with comorbidities had less successful outcomes. CONCLUSION: We conclude that in severe cases of laryngomalacia, supraglottoplasty has an important role to play in management. In children with comorbidities, the surgical results may be less successful. Therefore, we recommend that the decision to operate should be individualized, ensuring full disclosure to the family regarding the probable benefit along with the limitations of surgery.

Acute mastoiditis in children: is computed tomography always necessary?

OBJECTIVES: Acute mastoiditis (AM) is the most common intratemporal complication of acute otitis media in children. In the past decade, reports have indicated a rise in the incidence of AM in the pediatric population. A parallel rise in the use of computed tomography (CT) imaging has occurred. The rise in the use of CT scanning in the pediatric population, entraining with it a rise in pediatric brain irradiation, has led us to question the necessity of using CT for pediatric patients with AM. METHODS: We reviewed the medical files of pediatric patients who had AM in the years 2005 through 2007. RESULTS: Fifty patients were identified. The gender distribution was equal, and the ages ranged from 4 months to 12 years. Of the 46 patients who were admitted to our institution "de novo," only 2 underwent CT scanning on admission, and 4 other patients had CT performed during hospitalization. The majority of patients (92%) with AM did not have a CT scan performed and were treated conservatively with no complications. CONCLUSIONS: In most pediatric patients, CT does not seem to be indispensable in the diagnosis of AM. Conservative therapy and close follow-up seem to suffice for most.

Occluding the round window causes no change in threshold, but an increase in hearing loss following noise exposure.

AIM: To assess the effects of occluding the round window on the degree of hearing loss following exposure to broad band noise. DESIGN: Following opening of the middle ear bulla in both ears of ten sand rats, auditory nerve-brainstem evoked response (ABR) thresholds were determined in each ear separately using an insert earphone. The round window of one ear was then occluded with super-glue. The opposite ear was sham-operated. ABR thresholds were again assessed immediately. The animals were then exposed to 113 dB SPL broad band noise for 12 hours. 24 hours after the round window was occluded, which was 8-10 hours after the end of the noise exposure, ABR thresholds were again determined in each ear. In four control animals, the round window was blocked, but they were not exposed to noise. RESULTS: Following the noise exposure, the mean ABR threshold elevation in the round window blocked ears (54.5 +/- 5.5 dB) was significantly (p < 0.004) greater than that in the sham-operated ear (40.5 +/- 8.6 dB). In the four control ears, there was no change in ABR threshold 24 hours after the round window was occluded. CONCLUSION: Occluding the round window was not accompanied by a threshold elevation, but following noise exposure, the noise induced hearing loss was increased, probably by reducing the efficacy of an inherent protective mechanical mechanism.

Nasal blowing induces subcutaneous emphysema post penetrating mastoid tip trauma.

We describe the case of a child with an isolated penetrating trauma to the mastoid tip. Nasal blowing consequently induced air bubbles coming through the mastoid cutaneous fistula and causing extensive subcutaneous neck emphysema. A computed tomography (CT) demonstrated a right mastoid tip bone fracture with extensive cervical subcutaneous emphysema. The patient was treated conservatively with antibiotics and did not require operative intervention. His subsequent course was uncomplicated. This case emphasizes the importance of taking seriously even what seems to be a minor skin laceration.

Packing in endoscopic sinus surgery: is it really required?

OBJECTIVE: The aim of this study was to evaluate the routine use of packing or local hemostatic agents in endoscopic sinus surgery (ESS). METHODS: Packing and/or hemostatic agents were used only when necessary in 100 consecutive adult ESS patients in a tertiary academic hospital. Necessity for packing the nose after excessive bleeding was analyzed in relation to demographic characteristics, medical history, previous surgeries, current surgical procedure, type of anesthesia, and amount of intraoperative bleeding. RESULTS: Three patients who required packing because of other reasons (such as bolstering of mucosa) were excluded from the study. The remaining 97 patients included 61 males and 36 females between the ages of 16 to 86 (mean 44). Forty-nine patients underwent only ESS, 40 ESSs associated with nasal polypectomy, and 8 underwent other endoscopic procedures. Fifty-four underwent the operation under general anesthesia and 43 under local anesthesia. Intraoperative blood loss was less than 30 mL in 82 patients (85%), 30 to 50 mL in 11 (11%), and more than 50 mL in 4 (4%). In 89 patients (92%), packing or a hemostatic agent was not used. No patient had bleeding complications postoperatively. A comparison between patients who required packing to those who did not showed that the only statistically significant associations related to general anesthesia (P = 0.0082) and to the amount of intraoperative bleeding (P < 0.001). CONCLUSIONS: Most ESS procedures can be managed without packing or any other hemostatic measures. Local anesthesia, use of local vasoconstrictors, and careful operative technique minimize the need for nose packing, thus reducing patient's discomfort, postoperative complications, and cost of surgery.
