Nasal hypersensitivity and recurrent adenoids disease.

Authors studied nasal hypersensitivity (NH) behaviour on 41 subjects suffering from recurrent adenoids disease during their paediatric age. All subjects underwent clinical history, ENT examination, skin-test, RAST and non-specific nasal provocation test with histamine and assessment of the amount of sneezes. The results showed a familial transmission of the NH in 53.6% of cases, a hypogammaglobulinemia in 14.6% of cases. NH was present in 57% of subjects, much more with higher number of phlogosis, with higher possibility of familial transmission and with premature socialisation. These data showed a strict correlation between NH and recurrent adenoids disease. This NH didn't reduce in subjects undergone adenoidectomy and with time it conditioned the answer of the whole airways which could be noticed also in adulthood subjects. The presence of this NH had remarkable significance for diagnosis and therapeutic behaviour.

Obstructive sleep apnea syndrome in Thai children diagnosed by polysomnography.

Overnight polysomnography was conducted in 39 Thai children with clinically suspected obstructive sleep apnea syndrome (OSAS) during the years 1994 to 1996. Eighty-five percent of these children met the polysomnographic criteria of pediatric OSAS, 42.4% among whom had severe OSAS. Male : female ratio of children with OSAS was 4.5:1. The peak age at the time of diagnosis was 3 to 4 years. The most common predisposing factor was adenoidal and tonsillar hypertrophy. Adenoidectomy and/or tonsillectomy was the most effective therapeutic option. Recovery of symptoms was observed following surgery and nasal continuous positive airway pressure.

[Compromized postadenoidectomy respiration in a child with obstructive sleep apnea syndrome].

A two-year-old boy with a history of slow growth, snoring during sleep and adenoid hypertrophy underwent adenoidectomy and transtympanic drainage under general anesthesia. Immediately after extubation, severe inspiratory stridor and shallow labored breathing began and persisted over a period of two hours, in spite of corticoid administration and oxygen therapy. The signs receded partially when the patient was seated and with a mandibular traction maneuver. As symptoms persisted, foreign body obstruction was ruled out by examination of the cavum and upper airway under general anesthesia and with orotracheal intubation. The patient was transferred to the pediatric intensive care unit, where he remained intubated for 18 hours. After extubation, stridor and shallow labored breathing reappeared but gradually receded as the residual effects of sedation disappeared. The parents mentioned symptoms suggestive of obstructive sleep apnea syndrome (OSAS) occurring since the boy was 6 months old and that had worsened in recent months. OSAS in children is characterized by intermittent obstruction of the upper airway during sleep, causing snoring and periods of apnea/hypopnea that lead to hypoxemia and hypercapnia. The most frequent cause is hypertrophy of the adenoid and tonsils, and the treatment of choice is adenotonsillectomy, although the risk of postoperative respiratory distress in such children is high. It is important to rule out OSAS in children who are candidates for adenotonsillectomy so that such patients are not scheduled for ambulatory surgery, but rather given adequate postoperative monitoring and treatment.

[Post-obstructive pulmonary edema after adenoid-amygdalectomy].

A two-years-old boy with Down's Syndrome and a small interauricular communication was given priority scheduling for adenoidectomy and tonsillectomy to correct subacute obstruction of the upper airway. The only noteworthy event during surgery was an SpO2 of 92% during mechanical ventilation with FiO2 of 0.5 from no apparent cause. The patient suffered acute respiratory insufficiency due to the post-obstructive pulmonary edema in the hours immediately following surgery. The incidence of post-obstructive pulmonary edema is higher than might be expected, as symptoms can be interpreted as aspiration pneumonitis or left ventricular failure. Given the high prevalence of adenoiditis and tonsillitis with varying degrees of airway obstruction in children, we consider it useful to report this case. Such patients should be monitored carefully in the early postoperative period.

Relationship between tympanic membrane perforations and retained ventilation tubes.

OBJECTIVES: To determine the effects of prolonged ventilation tube retention on tympanic membrane healing and the efficacy of patching procedures used concomitantly at the time of tube removal. DESIGN: Retrospective chart review. SETTING: Tertiary referral academic institution. PATIENTS: Seventy-six patients aged 12 years and younger, with a total of 99 ears identified from January 1989 to December 1994. All patients underwent ventilation tube removal for prolonged tube retention or infection unresponsive to medical management. A minimum of 6 months of follow-up was required for inclusion. INTERVENTION: Ventilation tube removal under general anesthesia, with or without concomitant patching. OUTCOME MEASURES: All medical charts were reviewed for age, sex, indications for tube removal, tube retention time, type of patch used (if any), type of tube, outcome after removal, other medical problems, and previous surgical history. RESULTS: The perforation rate was significantly higher in children with tubes retained beyond 36 months (P=.02). History of previous adenoidectomy predicted poor outcome, with a rate of 47% vs 17% in patients with no such history (P=.002). Patching did not improve healing. No other patient factors significantly influenced the perforation rate. CONCLUSIONS: Ventilation tube retention longer than 36 months resulted in an increased perforation rate after surgical removal. Paper patching at the time of tube removal does not improve healing. Prospective studies are needed to confirm these findings and to determine the efficacy of other patching techniques.

Avoidance of primary post-tonsillectomy hemorrhage in a teaching program.

OBJECTIVE: To determine the incidence of primary post-tonsillectomy hemorrhage in a teaching institution by using a uniform technique, including a 3-minute relaxation of retraction before case termination and the use of bismuth subgallate. DESIGN: Case series. SETTING: Tertiary care academic pediatric center. PATIENTS: A 7-year retrospective study was performed by using the medical records of 1286 children without a bleeding abnormality who underwent tonsillectomy (with or without adenoidectomy). A uniform technique, proposed to reduce hemorrhage, was used for 705 children and was not used for 581 children. RESULTS: No episodes of primary hemorrhage (onset < or = 24 hours after surgery) occurred, and the incidence of delayed hemorrhage (onset >24 hours after surgery) was 1.1% in the study group. The primary hemorrhage rate of the study group was significantly lower (P = .007) than the rate for the reference group (0.0% vs 1.0%), as was the total hemorrhage rate (1.1% vs 4.1%) and the delayed hemorrhage rate (1.1% vs 3.1%). CONCLUSION: A uniform technique including the use of bismuth subgallate and reassessment of the tonsillar fossae after a 3-minute observation period reduces the incidence of primary tonsillar hemorrhage in a teaching institution setting.

Meta-analysis of pediatric tympanoplasty.

OBJECTIVE: To determine which preoperative conditions or surgical techniques may influence the success of tympanoplasty in the pediatric population. DATA SOURCES: A MEDLINE search of the English-language literature from 1966 to May 1997 was conducted using the search terms pediatric or child and tympanoplasty or myringoplasty. STUDY SELECTION: Articles that provided age-specific data on tympanoplasty or myringoplasty were included. Of the original 651 studies retrieved, 30 were accepted for inclusion. The principal reason for exclusion was inability to separate adult and pediatric results in series that combined both patient populations. DATA EXTRACTION: Success was defined as an intact tympanic membrane for the purpose of this review. Data were tabulated by consensus of 2 reviewers. DATA SYNTHESIS: The effect of surgical technique, prior adenoidectomy, presence of active infection, size of perforation, status of the contralateral ear, age, and eustachian tube function on healing of the tympanic membrane after surgery was assessed. Only those studies providing data on a given parameter of interest could be included when comparing each variable. Weighted means were compared and subjected to sensitivity analysis. Simple linear regression analysis was used to assess the effect of age on outcome. CONCLUSIONS: Greater success in healing of the tympanic membrane following tympanoplasty in children is seen with advancing age. None of the other parameters studied was shown to be a significant predictor of success. Guidelines for reporting results of tympanoplasty are presented.

Adenotonsillar enlargement in pediatric patients following solid organ transplantation.

OBJECTIVE: To evaluate the management of adenotonsillar hypertrophy in pediatric patients after transplantation. DESIGN: A retrospective medical record review after transplantation of all pediatric patients undergoing adenotonsillectomy at the University of California, Los Angeles, Medical Center during a 14-month period. SETTING: A tertiary care center. PATIENTS: There were 16 patients in our review, 11 boys and 5 girls. Nine patients had undergone liver transplantation, and 7 had undergone kidney transplantation. INTERVENTION: Fourteen patients underwent adenotonsillectomy, and 2 underwent adenoidectomy alone. Indications for surgical intervention included progressive symptoms of upper airway obstruction, recurrent tonsillitis, and/or evidence of notable adenotonsillar enlargement on physical examination. RESULTS: The mean +/- SD age at the time of transplantation was 3 years 1 month +/- 3 years 5 months. The mean +/- SD duration from allograft transplantation to adenotonsillectomy was 5 years 1 month +/- 2 years 4 months. Histopathologic examination revealed that 1 kidney transplant recipient had posttransplantation lymphoproliferative disorder. Eleven patients were found to have Epstein-Barr virus-related lymphoid hyperplasia. All patients experienced clinical resolution of their symptoms after surgery. CONCLUSIONS: Posttransplantation lymphoproliferative disorder is a condition associated with the Epstein-Barr virus infection in the setting of immunosuppression. Early presentation of posttransplantation lymphoproliferative disorder in children may be manifested by adenotonsillar enlargement. In addition to the role in relieving upper airway obstruction and decreasing upper respiratory tract infection, adenotonsillectomy may be critical in the prompt evaluation and treatment of posttransplantation lymphoproliferative disorder.

Laser myringotomy in different age groups.

OBJECTIVE: To study the qualities of laser myringotomy (LM) as a treatment for middle ear ventilation problems. DESIGN: Prospective study and follow-up of consecutive cases of adults, children, and infants. Patients were observed for up to 2 years. SETTING: Children underwent LM, with or without adenoidectomy, under general anesthesia in the operating room. Adults and infants underwent LM under topical anesthesia, as an outpatient procedure. PATIENTS: All consecutive patients with either secretory otitis media (SOM) (adults and children) or acute otitis media (AOM) (infants) who agreed to participate were included without selection. INTERVENTION: Myringotomy was performed using new laser equipment, enabling a 0.1-second ablation with changeable diameter. OUTCOME MEASURES: Close follow-up, with microscopic examination of all ears. Findings were noted on the medical charts. RESULTS: Among all age groups, 136 ears were followed up. Perforation lasted a mean 22 days in adults, 17 days in children, and 11 days in infants. Patient age was found to be a significant determining factor for duration of perforation (P =.002). Laser myringotomy in the anterior and inferior areas lasted longer than posterior LM (P<.001). In patients with SOM, during the time the LM was patent, all ears were ventilated. In children, 38% of SOM cases resolved after a single LM treatment. All infants with AOM recovered promptly without antibiotic treatment. CONCLUSIONS: Laser myringotomy is a convenient, quick procedure that can be performed in the medical office with the use of topical anesthesia and is suitable for patients with AOM or for those who need short-term ventilation for SOM. It was found to be a safe alternative to ventilation tubes in these patients. In AOM, it was used instead of antibiotics and gave prompt relief from symptoms and cure of the AOM.

Efficacy of gastric aspiration in reducing posttonsillectomy vomiting.

OBJECTIVE: To determine the effectiveness of postoperative gastric decompression in reducing the incidence and complications associated with vomiting following tonsillectomy. DESIGN: A prospective, randomized controlled study. SETTING: Private office and clinic of a university teaching hospital and research center. PATIENTS: Eighty pediatric patients ranging in age from 22 months to 11 years, American Society of Anesthesiologists class I or II, undergoing tonsillectomy with or without adenoidectomy were enrolled in the study. Six were excluded from the final analysis, 5 because of failure of the parents to complete and return the data forms and 1 because of postoperative bleeding. Of the 74 patients included in the study, 35 were in the control group and 39 were in the study group. INTERVENTIONS: The 39 patients in the study group underwent postoperative aspiration of gastric contents with an orogastric tube placed under direct visualization while the patient was still under general anesthesia. The 35 patients in the control group did not undergo gastric aspiration following surgery. MAIN OUTCOME MEASURES: The incidence of vomiting, the number of episodes of vomiting before and after hospital discharge, the total volume of emesis, the postoperative length of stay, the need for rescue antiemetic prophylaxis, and the number of readmissions to the hospital for persistent vomiting were noted. RESULTS: No statistically significant difference (P<.05) was noted between the control group and the study group for the percentage of patients experiencing vomiting (74% vs 85%), the mean number of episodes of vomiting before (2.6 vs 2.8) and after (0.8 vs 0.7) hospital discharge, the mean volume of emesis (157 mL vs 222 mL), the postoperative length of stay (394 minutes vs 334 minutes), the percentage of patients requiring rescue antiemetics (34% [12 patients] vs 33% [13 patients]), and the percentage of unplanned admissions because of vomiting (9% [3 patients] vs 15% [6 patients]). CONCLUSION: Our results indicate that gastric aspiration does not decrease the incidence of vomiting following tonsillectomy.

Quality-of-life outcomes after surgical intervention for otitis media.

OBJECTIVE: To assess the change in disease-specific quality of life in children with recurrent acute otitis media and/or chronic otitis media with effusion treated with surgical intervention. DESIGN: Prospective questionnaire-based outcome study. SETTING: An academic pediatric otolaryngology practice. PARTICIPANTS: Consecutive series of 123 children referred for surgical treatment of recurrent acute otitis media and/or chronic otitis media with effusion. INTERVENTION AND METHODS: Surgery included bilateral myringotomy and tympanostomy tube placement either alone or with adenoidectomy. An otitis media disease-specific questionnaire was administered before and after surgical intervention. MAIN OUTCOME MEASURES: Comparison of the mean percentage change in total ear symptom score between presurgery and postsurgery scores at 1 and 6 months after surgery. RESULTS: The mean percentage change in total ear symptom score was a 74.5% improvement (P<.001) at the 1-month follow-up and a 59.8% improvement (P<.001) at the 6-month follow-up. Parental worry related to the child's ear problems was also significantly decreased, with a mean otitis media disease-specific questionnaire score of 3.43 (P<.001) at 1 month and 2.64 (P<.001) at 6 months after surgery. When caregivers were asked if they would have their child undergo tympanostomy tube placement if they had to make the decision again, 91% and 84% responded yes at the 1- and 6-month follow-up, respectively. CONCLUSIONS: The disease-specific quality of life of children with recurrent acute otitis media and/or chronic otitis media with effusion with appropriate surgical indications significantly improved after surgical intervention. The amount of parental worry concerning their children's ear problems also significantly improved following surgery, and most caregivers would opt again for tube placement.

Establishing normative voice-related quality of life scores within the pediatric otolaryngology population.

OBJECTIVE: To establish normative values for voice-related quality of life across a broad pediatric otolaryngology population using the Pediatric Voice Outcome Survey (PVOS). DESIGN: Longitudinal study. SETTING: Multiphysician outpatient pediatric otolaryngology practice. METHODS: The PVOS was completed by 385 parents of children and adolescents aged 2 to 18 years. Of the 385 parents, 75 were readministered the instrument 2 weeks after no intervention had been provided. Data were collected regarding the patients' age, main diagnosis, and operative intervention. RESULTS: The PVOS demonstrated robust internal consistency with an overall Cronbach alpha value of.70. Test-retest reliability demonstrated a weighted kappa value of 0.89 (95% confidence interval, 0.84-0.95) The mean +/- SD converted score (based on a 0-100 scale) for the overall population was 80.5 +/- 19.9. Converted PVOS scores are provided for each subpopulation according to main diagnosis. The PVOS scores varied significantly according to age (P<.05) and preoperative and postoperative status following adenoidectomy (P<.05). CONCLUSION: The PVOS represents a valid and reliable instrument to measure voice-related quality of life in a broad pediatric otolaryngology population.

Detection of Helicobacter pylori and its CagA gene in tonsil and adenoid tissues by PCR.

OBJECTIVE: To determine the presence of Helicobacter pylori and, if detected, the prevalence of the CagA gene in adenotonsillectomy specimens by polymerase chain reaction (PCR). DESIGN: A prospective clinical trial. SETTING: Tertiary referral center. PATIENTS AND METHODS: The study population comprised 23 patients who had undergone adenoidectomy, tonsillectomy, or adenotonsillectomy under local or general anesthesia. Helicobacter pylori DNA was extracted from 3-mm-diameter tissue samples obtained from each tonsil and adenoid tissue specimens. The amplifications were performed for the 16S ribosomal RNA (rRNA) and CagA genes of H pylori in the samples of which H pylori DNA was detected. RESULTS: In examining all the samples, 7 (30%) of 23 patients were shown to be positive for H pylori DNA, 5 (71%) of whom also possessed the CagA gene. CONCLUSIONS: Tonsil and adenoid tissues may be an ecological niche of the mouth without regard to transient or permanent colonization. Oral-oral transmission may be a possible mode of spread of H pylori.

Temperature-controlled radiofrequency tonsil reduction in children.

OBJECTIVE: To evaluate the safety and efficacy of temperature-controlled radiofrequency tonsil reduction in the treatment of children with a sleep-related breathing disorder associated with tonsillar obstructive hypertrophy. DESIGN: Prospective, nonrandomized, case series feasibility study of children meeting the criteria for tonsillectomy or adenotonsillectomy for the treatment of an obstructive sleep-related breathing disorder. SETTING: Community-based hospital. Patients Ten children, aged 4 to 13 years, presenting consecutively to a community-based otolaryngology practice with tonsillar or adenotonsillar obstructive hypertrophy implicated clinically in causing a sleep-related breathing disorder; their parents consenting to temperature-controlled radiofrequency tonsil reduction instead of surgical tonsillectomy. Intervention Temperature-controlled radiofrequency tonsil reduction, along with surgical adenoidectomy, if adenoids were present, under general anesthesia. MAIN OUTCOME MEASURES: Tonsil size reduction, treatment morbidity, and symptom improvement with follow-up to 1 year. Baseline and 3-month posttreatment polysomnographic data were used. RESULTS: There was a reduction in tonsil size at 1 year of 75.0% on average, without evidence of regrowth during the 1-year follow-up. All children were drinking liquids in the recovery room, and most were eating soft diets within 6 hours; 8 of the 10 children were eating a normal diet by day 5. On average, the return to normal activity was 3.9 days, with 2.9 days of parental loss of work time. Quality-of-life variables all improved. Snore indexes decreased by 88.6%. Polysomnography at 3 months revealed an 84.2% reduction in the apnea index and a 52.3% reduction in the apnea/hypopnea index. There were no complications. CONCLUSION: Temperature-controlled radiofrequency tonsil reduction seems to be a safe, effective, and minimally morbid treatment for tonsil hypertrophy in children with obstructive sleep-related breathing disorders.

Validation of the Pediatric Voice-Related Quality-of-Life survey.

OBJECTIVE: To validate the Pediatric Voice-Related Quality-of-Life (PVRQOL) survey, which was designed to assess voice changes over time in the pediatric population. DESIGN: Prospective longitudinal study. SETTING: Outpatient pediatric otolaryngology office practice. PARTICIPANTS: One hundred twenty parents of children aged 2 through 18 years having a variety of otolaryngological diagnoses including disorders that affect the voice. INTERVENTIONS: The previously validated Pediatric Voice Outcomes Survey and the PVRQOL were jointly administered to the parents of the study participants. Test-retest reliability was accomplished by having 70 caregivers repeat the instrument 2 weeks after the initial visit. The Cronbach alpha value was calculated to determine reliability. Instrument validity was determined by examining convergent and discriminant validity. MAIN OUTCOME MEASURE: Correlation of PVRQOL scores with Pediatric Voice Outcomes Survey scores. RESULTS: Reliability of the PVRQOL was established by evaluating the Cronbach alpha value (.96; P<.001) and by test-retest reliability (weighted kappa value, 0.8). Validity of the PVQROL was tested by evaluating its ability to show significant change in voice-related quality-of-life after adenoidectomy (discriminant validity) (P<.001). The PVQROL also proved valid when the overall score was correlated with the previously validated Pediatric Voice Outcomes Survey (r = 0.7; P<.001). CONCLUSION: The PVRQOL is a more comprehensive survey than the previously validated Pediatric Voice Outcomes Survey and is another valid instrument to examine the health-related quality-of-life issues in pediatric voice disorders.

Cardiopulmonary changes secondary to chronic adenotonsillitis.

Thirty children with lower respiratory tract infection of varying degrees secondary to chronic tonsillitis and/or enlarged adenoids were studied clinically and roentgenographically. Symptoms and signs of alveolar hypoventilation and signs of cor pulmonale were present in two of them. These symptoms and signs improved markedly after adenoidectomy and tonsillectomy. The relationship of the lung changes to the incidence of cor pulmonale is discussed. The development of recurrent attacks of severe lower respiratory tract infection secondary to diseased tonsils and adenoids is believed to play an important role in the pathogenesis of cor pulmonale in children with upper respiratory tract obstruction due to chronically enlarged tonsils and adenoids.

Nasal respiratory function and craniofacial growth.

Nasal respiratory function and its relationship to growth development of the craniofacial structure has been a subject of interest and controversy for over 100 years. The otolaryngologist as the primary physician with responsibility of managing the upper respiratory tract is obviously most intimately involved with diagnosis and treatment of upper respiratory tract problems. To further evaluate the evidence regarding causes of craniofacial growth, a study was done involving pretreatment orthodontic subjects and their manifestation of classic signs of adenoid facies ("long-face syndrome"). Randomly selected were 106 subjects, ranging in age from 6 to 13 years, for evaluation of the facial features and medical history associated with long-face syndrome. No conclusive proof was found that nasal respiratory obstruction alters facial growth development. Studies of the nasal respiratory function need to be done utilizing clear definitions of respiratory mode and objective; reproducible techniques of measuring respiratory modes must be employed. Highly selected orthodontic patients can benefit from adenoidectomy and/or tonsillectomy.

Dynamics of eardrum changes following secretory otitis. A prospective study.

Children with secretory otitis who, during the period from 1970 through 1975, had been treated with adenoidectomy and insertion of ventilating tubes were reexamined three to eight years after treatment and, again, ten to 16 years after treatment. The changes of the tympanic membranes were analyzed with regard to the occurrence of attic retractions and changes of the pars tensa of the membranae tympani. At the first follow-up examination, varying degrees of attic retractions were found in 37% of ears and, at the second follow-up examination, in 27% of ears. This general improvement was mainly due to normalization of the slight retractions, whereas the frequency of severe retractions increased. Pathology of the pars tensa of the membranae tympani was found in 57% of ears at the first examination and comprised the following: tympanosclerosis (19%), tympanosclerosis and atrophy (10%), atrophy (22%), atrophy and pexi (3%), and adhesive otitis (3%). At the second follow-up examination, pathology of the pars tensa of the membranae tympani occurred in 58.05% of ears and was distributed as follows: tympanosclerosis (26%), atrophy and tympanosclerosis (11%), atrophy (14%), atrophy and pexi (5%), adhesive otitis (2%), and sinus cholesteatoma (0.5%).
