Clinical outcomes of ventilation tube placement in children with cleft palate

Tympanostomy Tubes: Are They Necessary? A Systematic Review on Implementation in Cleft Care

OBJECTIVE

To understand the indication for and the effects of early ventilation tube insertion (VTI) on hearing and speech for patients with cleft lip and/or palate (CLP).

DESIGN

We conducted a Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA)-guided systematic review of relevant literature.

SETTING

Setting varied by geographical location and level of clinical care across studies.

PATIENTS, PARTICIPANTS

Patients with CLP who underwent VTI were included.

INTERVENTIONS

No interventions were performed.

MAIN OUTCOME MEASURE(S)

Primary outcome measures were hearing and speech following VTI. Secondary outcome measures were tube-related and middle ear complications. Early VTI occurred before or at time of palatoplasty while late VTI occurred after palatoplasty.

RESULTS

Twenty-three articles met inclusion criteria. Articles varied among study design, outcome measures, sample size, follow-up, and quality. Few studies demonstrated support for early VTI. Many studies reported no difference in hearing or speech between early and late VTI. Others reported worse outcomes, greater likelihood of complications, or needing repeat VTI following early tympanostomy placement. Several studies had significant limitations, including confounding variables, small sample size, or not reporting on our primary outcome.

CONCLUSIONS

No consistency was found regarding which patients would benefit most from early VTI. Given the aforementioned variability and sub-optimal methodologies, additional studies are warranted to provide stronger evidence regarding VTI timing in cleft care.

The Impact of Lateral Relaxing Incision on Middle Ear Function in Cleft Palate Repair

Children with cleft palate are susceptible to otitis media with effusion. This study aimed to investigate the effect of lateral relaxing incision (RI) on middle ear function in cleft palate patients who underwent palatoplasty using double-opposing Z-plasty (DOZ). This is a retrospective study of patients who underwent bilateral ventilation tube insertion concurrently with DOZ, wherein RI was selectively performed on the right side of the palate (Rt-RI group) or not (No-RI group). The frequency of VTI, duration of the first ventilation tube retention, and hearing outcomes at the last follow-up were reviewed. Outcomes were compared using the χ2 test and t test. A total of 126 treated ears from 63 non-syndromic children (18 male, 45 female) with cleft palate were reviewed. The mean age at surgery was 15.8±6.17 months. There were no significant differences in the frequency of ventilation tube insertion between the right and left ears within the Rt-RI group or between the Rt-RI and no-RI groups in the right ear. Subgroup analysis for ventilation tube retention time, auditory brainstem response thresholds, and air-conduction pure tone averages showed no significant differences. In the DOZ, the use of RI had no significant effects on middle ear outcomes during 3 years of follow-up. Relaxing incision seems to be safe without concern for middle ear function in children with cleft palate.

Clinical practice guidelines for the diagnosis and management of otitis media with effusion (OME) in children in Japan - 2022 update

This is an update of the 2015 Guidelines developed by the Japan Otological Society and Oto-Rhino-Laryngeal Society of Japan defining otitis media with effusion (OME) in children (younger than 12 years old) and describing the disease rate, diagnosis, and method of examination. Recommended therapies that received consensus from the guideline committee were updated in consideration of current therapies used in Japan and based on available evidence.

METHOD

Regarding the treatment of OME in children, we developed Clinical Questions (CQs) and retrieved documents on each theme, including the definition, disease state, method of diagnosis, and medical treatment. In the previous guidelines, no retrieval expression was used to designate a period of time for literature retrieval. Conversely, a literature search of publications from March 2014 to May 2019 has been added to the JOS 2015 Guidelines. For publication of the CQs, we developed and assigned strengths to recommendations based on the collected evidence.

RESULTS

OME in children was classified into one group lacking the risk of developing chronic or intractable disease and another group at higher risk (e.g., children with Down syndrome, cleft palate), and recommendations for clinical management, including follow-up, is provided. Information regarding management of children with unilateral OME and intractable cases complicated by adhesive otitis media is also provided.

CONCLUSION

In clinical management of OME in children, the Japanese Clinical Practice Guidelines recommends management not only of complications of OME itself, such as effusion in the middle ear and pathologic changes in the tympanic membrane, but also pathologic changes in surrounding organs associated with infectious or inflammatory diseases.

Relationship between cleft palate width and otitis media

Objectives

To investigate the relationship between cleft width and otitis media (OM) and to determine whether a wide cleft palate (CP) is a risk factor of the incidence, type, amount of middle ear effusion, and prolonged morbidity in OM.

Study Design

Retrospective cohort study.

Methods

Children with CP who underwent palatoplasty between 2014 and 2018 were analyzed. Cleft width was measured at palatoplasty. The incidence of otitis media with effusion (OME) and acute otitis media (AOM), the type and amount of middle ear effusion, and OME duration and age at resolution were assessed in relation to cleft width.

Results

One hundred eighteen children were included. The CP types were Veau I in 16, II in 35, III in 48, and IV in 19 patients. The incidence of OME and AOM before palatoplasty was 83.1% and 49.2%, respectively. Cleft width did not differ significantly between patients with or without OME but was significantly greater in those with, than in those without, AOM (p < .001), in those with mucoid, than in those with serous, effusion (p = .012), and in those with complete, than in those with partial, effusion (p = .01). Regardless of cleft width or type, OME persisted for a median duration of 50 months.

Conclusions

Cleft width was significantly associated with the incidence of AOM and the type and amount of middle ear effusion before palatoplasty. However, it was not significantly related to the incidence, age at resolution, or duration of OME. Regardless of cleft width or type, OM in children with CP requires long-term follow-up. Level of Evidence: 2b.

Prognosis of otitis media with effusion in pediatric patients with cleft palate during language-acquisition period treated by simultaneous tympanostomy tube placement with palatoplasty

OBJECTIVE

Cleft palate (CP) in children is frequently complicated by otitis media with effusion (OME) due to Eustachian tube dysfunction. Although tympanostomy tube (TT) placement can be beneficial in the treatment of OME to prevent short-term hearing loss, there is no consensus regarding the indications for and timing of TT insertion. The present study was performed to define the safety and effectiveness of simultaneous TT placement with palatoplasty during the language-acquisition period.

METHODS

We retrospectively reviewed the medical charts of pediatric patients who underwent palatoplasty for CP in a tertiary medical center, Kyoto University Hospital, from June 2010 to October 2018. The TT retention time was estimated using the Kaplan-Meier method. The incidence of OME recurrence was compared among four Veau classification groups based on the patients' sex, type of CP, median TT retention time, and type of fluid.

RESULTS

Seventy-six subjects (150 ears) were enrolled in the study. The median follow-up duration was 48.7 months (range, 18.2-108.0 months) after the first TT placement. A first TT retention time of <20.1 months was a significant risk factor for OME recurrence. Subjects with maxillofacial anomaly complex and subjects with cleft lip and palate and an alveolar cleft showed a significantly higher OME recurrence rate than subjects with clefts only in the hard and/or soft palate. There was no significant difference in the occurrence of sequelae between subjects with only a single TT placement and subjects with more than one TT placement.

CONCLUSIONS

Based on the findings of the present study, it is reasonable to perform TT insertion at the same time as palatoplasty on patients who meet the indications. This technique may reduce the number of times the patient requires general anesthesia and maintain good middle ear condition during the period of language acquisition between 1 and 3 years of age.

Efficacy of Ventilation Tube Insertion with Palatal Repair for Otitis Media in Cleft Palate: Meta-Analysis and Trial Sequential Analysis

Cleft palate is the most common congenital facial deformity and may result in multiple sequelae and disabilities. One common comorbidity is refractory otitis media with effusion (OME), as patients with cleft palate have impaired eustachian tube function with alteration of the nearby muscular structures. Ventilation tube insertion (VTI) is regarded as an effective mean to address OME in addition to palatal repair surgery. However, controversy regarding the efficacy of VTI and the timing of VTI remains. We aimed to assess the efficacy of VTI with palatal repair for cleft palate on OME development via a meta-analysis with systematic review and trial sequential analysis (TSA). Studies including patients with cleft palate who underwent palatal repair with or without VTI were considered eligible. After searching the Cochrane Library, PubMed, EMBASE, Web of Science, Scopus and China National Knowledge Infrastructure (CNKI) from inception through 5 September 2021, 9 studies involving 929 patients were included. Overall, a significantly higher OME-free rate was noted in those who underwent VTI and palatal repair than in those who underwent palatal repair alone (OR, 2.73; 95% CI, 1.37 to 5.42; p = 0.004; I2 = 84%). Subgroup analysis revealed that the OME-free rate remained higher in the concurrent VTI group (OR, 3.29; 95% CI, 1.64 to 6.59; p < 0.001; I2 = 81%). TSA indicated that all the analyses provided conclusive results by meeting the required information size and Z-value. The meta-analysis indicated that VTI is an effective procedure to prevent OME in patients with cleft palate and that VTI is beneficial when performed concurrently with palatal repair surgery.

Internationally adopted children with cleft lip and/or cleft palate: Middle ear findings and hearing during childhood

OBJECTIVE

Adopted children with cleft lip and/or cleft palate form a diverse group of patients. Due to increased age at palatal repair, adopted children have a higher risk of velopharyngeal insuffiency and poor speech outcome. Delayed palate repair may also lead to longer lasting Eustachian tube dysfunction. Decreased function of the Eustachian tube causes otitis media with effusion and recurrent acute otitis media, which can lead to other middle ear problems and hearing loss.

METHODS

One-hundred-and-thirty-two adopted children treated by the Cleft palate team in Wilhelmina Children's Hospital during January 1994 and December 2014 were included. Retrospectively, middle ear findings, the need for ventilation tube insertion and hearing during childhood were assessed. Findings were compared with 132 locally born children with cleft lip and/or cleft palate.

RESULTS

Adopted children had a mean age of 26.5 months old when they arrived in our country. After the age of two the total number of otitis media with effusion episodes and the need for ventilation tube placement did not significantly differ among adopted and non-adopted children. Adopted children had significantly more tympanic membrane perforations. Hearing threshold levels normalized with increasing age. Although within normal range, adopted children showed significantly higher pure tone averages than locally born children when they were eight to ten years old.

CONCLUSION

In general, adopted patients with cleft lip and/or cleft palate did not have more middle ear problems or ventilation tubes during childhood. However, theyhave more tympanic membrane perforations.

Surveillance of Otitis Media With Effusion in Thai Children With Cleft Palate

Objective:

To study the incidence and outcome of management of otitis media with effusion in Thai children with cleft palate.

Design:

Retrospective cohort study in the tertiary care center.

Patients:

Ninety-five children with cleft palate were referred for ear evaluation, from June 1997 to January 2015. Fifteen children (15.8%) had associated craniofacial syndromic anomalies.

Main outcome measures:

Cumulative incidence of otitis media with effusion, rate of ventilation tube insertion, duration of indwelling tubes, hearing outcome, and complications of ventilation tubes.

Results:

Ear examinations were done every 8 to 12 weeks throughout the study. Cumulative incidence of otitis media with effusion was 53.7% in children within 12 months of age and 81.1% within 24 months of age. At the end of the study, all of the patients had at least 1 episode of otitis media with effusion. Eighty-eight children (92.6%) had palatoplasty, and there was no significant difference in the incidence of otitis media before and after palatoplasty. The mean hearing level at recruitment was 40.8 ±18.4 dB. Ventilation tube insertion was done in 76 patients (80%). The median time for indwelling tubes was 11.7 months. Rate of ventilation tube insertion was 0.5/year. The mean hearing level at last follow-up was 23.5 ± 14 dB. Otorrhea through tube was found in 24 cases (31.6%).

Conclusion:

Otitis media with effusion was common in Thai children with cleft palate. Surveillance of middle ear effusion and ventilation tube insertion contributed to a favorable hearing outcome.

Should Children With Cleft Palate Receive Early Long-Term Tympanostomy Tubes

Objectives:

To determine whether children with cleft palate might benefit from early long-term tympanostomy tubes with the hypothesis that receiving multiple tubes is associated with shorter duration of first tubes.

Design:

Retrospective cohort study.

Setting:

Tertiary care children’s hospital.

Participants:

Records from 401 consecutive children with cleft palate ± cleft lip, born April 2005 to April 2010, were reviewed. After exclusion of children with cleft repair at an outside hospital, no follow-up after 5 years of age, intact secondary palate, no tubes, or tube replacement at palatoplasty, 105 children remained.

Main Outcome Measure:

Number of tubes.

Results:

Armstrong grommet tubes were placed at a median age of 6.7 months (range 2.3-19.6 months). Tubes were replaced in 55.3% of patients, with 34.0% receiving ≥3 sets. Duration of first tubes was significantly longer for children with 1 set of tubes compared with those with multiple sets (median 26 vs 19 months, P = .004). Otorrhea, but not perforation, was associated with longer duration of first tubes (median 27 vs 20.5 months, P = .028). Cleft type did not impact the proportion of patients with multiple tubes. Median age at last tube placement for children with multiple tubes was 5.0 years (range 1.9-8.7 years).

Conclusion:

Short duration of first tubes is associated with receiving multiple tubes. Because most patients require repeat tubes and many require tubes until school age, there is a significant need for controlled, prospective trials of early long-term tube placement in this population.

Effectiveness of Tympanostomy Tubes for Otitis Media: A Meta-analysis

CONTEXT

Tympanostomy tube placement is the most common ambulatory surgery performed on children in the United States.

OBJECTIVES

The goal of this study was to synthesize evidence for the effectiveness of tympanostomy tubes in children with chronic otitis media with effusion and recurrent acute otitis media.

DATA SOURCES

Searches were conducted in Medline, the Cochrane Central Trials Registry and Cochrane Database of Systematic Reviews, Embase, and the Cumulative Index to Nursing and Allied Health Literature.

STUDY SELECTION

Abstracts and full-text articles were independently screened by 2 investigators.

DATA EXTRACTION

A total of 147 articles were included. When feasible, random effects network meta-analyses were performed.

RESULTS

Children with chronic otitis media with effusion treated with tympanostomy tubes compared with watchful waiting had a net decrease in mean hearing threshold of 9.1 dB (95% credible interval: -14.0 to -3.4) at 1 to 3 months and 0.0 (95% credible interval: -4.0 to 3.4) by 12 to 24 months. Children with recurrent acute otitis media may have fewer episodes after placement of tympanostomy tubes. Associated adverse events are poorly defined and reported.

LIMITATIONS

Sparse evidence is available, applicable only to otherwise healthy children.

CONCLUSIONS

Tympanostomy tubes improve hearing at 1 to 3 months compared with watchful waiting, with no evidence of benefit by 12 to 24 months. Children with recurrent acute otitis media may have fewer episodes after tympanostomy tube placement, but the evidence base is severely limited. The benefits of tympanostomy tubes must be weighed against a variety of associated adverse events.

Hearing thresholds and ventilation tube treatment in children with unilateral cleft lip and palate

OBJECTIVE

Children with cleft lip and palate have a high prevalence of otitis media with effusion (OME) which is often associated with a fluctuating, conductive hearing loss in the low and mid-frequencies and a risk for permanent hearing loss in the higher frequencies. Although common, there is no consensus on the treatment of OME with ventilation tubes. The aim of this study is to document if the risk for permanent hearing loss and acquired cholesteatoma increases due to treatment with ventilation tubes (VT treatments) during childhood in a group of children with cleft lip and palate.

METHODS

A retrospective medical chart review of 33 children (25 boys and 8 girls) born with unilateral cleft lip and palate (UCLP) was completed. Audiological data (results of hearing sensitivity tests, the total number of hearing tests, and number of VT treatments) were extracted from medical records from when the children were 4-7 and >7-10 years of age.

RESULTS

The hearing thresholds in the speech frequencies improved with age (p < 0,05) but a minority of the children continued to present with elevated hearing thresholds in the higher frequencies at >7-10 years of age. There were no significant correlations between number of VT treatments and hearing thresholds at >7-10 years. Four of the 33 children presented with complications: two children exhibited perforations of the ear drum (6.1%) and two children developed unilateral cholesteatoma (6.1%).

CONCLUSION

In the current study, the hearing sensitivity of children with cleft lip and palate improved with age. However, this improvement was not seen in the higher frequencies. Twelve percent of the children experienced complications following VT treatments. Due to these complications, it is recommended that all children with cleft palate should have routine follow-ups by an ENT doctor and audiologist. As part of the routine follow-up care, hearing assessments should be performed before and after VT treatments.

The Impact of Tympanostomy Tubes on Speech and Language Development in Children with Cleft Palate

Objective Describe the impact of hearing loss, tympanostomy tube placement before palatoplasty, and number of tubes received on speech outcomes in children with cleft palate. Study Design Case series with chart review. Setting Tertiary care children's hospital. Subjects and Methods Records from 737 children born between April 2005 and April 2015 who underwent palatoplasty at a tertiary children's hospital were reviewed. Exclusion criteria were cleft repair at an outside hospital, intact secondary palate, absence of postpalatoplasty speech evaluation, sensorineural or mixed hearing loss, no tubes, first tubes after palatoplasty, or first clinic after 12 months of age. Data from 152 patients with isolated cleft palate and 166 patients with cleft lip and palate were analyzed using Wilcoxon rank-sum, χ², and Fisher exact test and logistic regression. Results Most patients (242, 76.1%) received tubes before palatoplasty. Hearing loss after tubes, but not before, was associated with speech/language delays at 24 months ( P = .005) and language delays ( P = .048) and speech sound production disorders (SSPDs, P = .040) at 5 years. Receiving tubes before palatoplasty was associated with failed newborn hearing screen ( P = .001) and younger age at first posttubes type B tympanogram with normal canal volume ( P = .015). Hearing loss after tubes ( P = .021), language delays ( P = .025), SSPDs ( P = .003), and velopharyngeal insufficiency ( P = .032) at 5 years and speech surgery ( P = .022) were associated with more tubes. Conclusion Continued middle ear disease, reflected by hearing loss and multiple tubes, may impair speech and language development. Inserting tubes before palatoplasty did not mitigate these impairments better than later tube placement.

Grommet Surgery in Children with Orofacial Clefts in England

Objective

To assess grommet insertion practice in the first 5 years of life among children with an orofacial cleft in England.

Design

Analysis of national administrative data of hospital admissions.

Setting

National Health Service hospitals, England.

Patients

Patients born between 1997 and 2005 who underwent surgical cleft repair.

Intervention

Children receiving grommets before the age of 5 years.

Outcome Measures

The proportion of children receiving grommets before the age of 5 years, the timing of the first grommet insertion, and the proportion of children having repeat grommet insertions were examined according to cleft type, the absence or presence of additional anomalies, socioeconomic deprivation, and region of residence.

Results

The study included 8,269 children. Before the age of 5 years, 3,015 (36.5%) children received grommets. Of these, 33.2% received their first grommets at primary cleft repair and 33.3% underwent multiple grommet insertion procedures. The most common age for the first procedure was between 6 and 12 months. Children with a cleft affecting the palate were more likely to receive grommets than children with a cleft lip alone (45.5% versus 4.5%). Grommet insertion practice also varied according to year of birth, absence or presence of additional anomalies, socioeconomic deprivation, and region of residence.

Conclusion

Grommets practice in children with a cleft appears to vary according to their clinical characteristics. The differences in practice observed according to deprivation and region of residence need to be further explored.

Neurological Development of Children With Isolated Robin Sequence Treated With Nasopharyngeal Intubation in Early Infancy

The study assessed the neurodevelopment of children with isolated Robin sequence (IRS) and evaluated if children treated exclusively with nasopharyngeal intubation (NPI) present delay in neurological development. The prospective and cross-sectional study was conducted at the Hospital for Rehabilitation of Craniofacial Anomalies, Brazil. Children with IRS were divided into two groups according to the type of treatment in early infancy: 38 were treated with NPI (more severe cases) and 24 with postural treatment (less severe cases). Regarding interventions, children were assessed at 2 to 6 years of age using the Denver II Developmental Screening Test (Denver II) and Neurological Evolutionary Examination (NEE). According to Denver II, 73.7% in the NPI group and 79.2% in the postural group presented normal development. This result was similar to the results of different studies in the literature with typical population. Considering all areas of development, there were no significant differences in Denver II between the NPI and postural groups (P = .854). In the NPI group, 89.5% of children and 87.5% in the postural group presented normal development in NEE. Language was the most affected area, as 18.4% and 20.8% of children in NPI and postural group, respectively, presented risk for delay in the Denver II. The increased risk for delay in language area was probably due to anatomical conditions of the muscles involved in speech, and to hearing oscillations, as 47.4% in NPI group and 58.3% in postural group underwent myringotomy. IRS treated with NPI had neurological development similar to those in less severe cases. Children treated exclusively with NPI did not present delay in neurological development.

The effect of early routine grommet insertion on management of otitis media with effusion in children with cleft palate

PURPOSE

The aim of the study is to compare long term otoscopic and audiological findings of cleft palate patients with or without early grommet insertion.

METHODS

Cleft palate patients followed-up in Hacettepe University between 2008 and 2013 were included in the study. Age, gender, cleft types and palate surgery data, grommet tube insertion history and otological - audiological evaluations of the patients were recorded. Patients were evaluated in three groups according to grommet insertion history: A-early routine grommet insertion, B-grommet insertion during follow-up, C-no grommet insertion. Otological and audiological findings were compared.

RESULTS

There were 154 patients in the study, with a median age of 7.7 years. There were 67 patients in group A (43.5%), 22 patients in group B (14.3%) and 65 patients in group C (42.2%). OME was identified significantly higher in group A and normal otoscopic examination findings were higher in group C. Complications showed a higher rate than other otoscopic findings in group B patients. There was no significant difference for any frequencies in between the groups in terms of mean air-bone gap (ABG) values. There were 20 grade I, 25 grade II, 77 grade III and 32 grade IV patients in the study according to the Veau classification.

CONCLUSION

Prophylactic grommet insertion may not be applied as some cleft palate patients with no OME. Wait and see protocol can be recommended for these patients, and they should be followed-up up closely to avoid complications. If the effusion does not recover or tympanic membrane changes occur in follow-up, grommet insertion should be considered.

The rationale for preventive treatments for early post-tympanostomy tube otorrhea in persistent otitis media with effusion

Some studies have shown that post-tympanostomy tube otorrhea (PTTO) is a common complication after tympanostomy tube insertion. There are wide range of controversies about the incidence of PTTO and different methods of preventive treatment. The aim of this study was to determine the incidence of early PTTO in persistent otitis media with effusion in our centers. We also investigated the effect of preventive treatments on the incidence of early PTTO in children with persistent otitis media with effusion. This multi-central study comprised 536 ears belonging to children with otitis media and effusion for at least 3 months, referred for complications arising from post-tympanostomy tube insertion. The patients were randomly divided into three treatment and control groups. In the first group of patients, the middle ear cavity was irrigated with isotonic saline after myringotomy. The second group received oral amoxicillin three times a day for 7 days postoperatively. The third group had similar treatment as the second group, in addition to topical ciprofloxacin drop, 4 drops three times a day for 3 days after operation. The control group did not undergo any treatment. Early post-tympanostomy tube otorrhea was detected in 6 ears (1.1 %), including 3 (2.2 %) from the control group and 3 (2.3 %) from the first group. There was no statistically significant difference in early PTTO between integrated treatment groups and control group (P = 0.111). As the total rate of early post-tympanostomy tube otorrhea was very low, there was no significant difference between the 3 treatment groups and control group. Our study did not support the routine use of preventive therapy. A period of at least 3 months watchful waiting before tympanostomy tube insertion may help reduce the incidence of PTTO.

Grommets for otitis media with effusion in children with cleft palate: a systematic review

BACKGROUND AND OBJECTIVE

No consensus has yet been reached with regard to the link between otitis media with effusion (OME), hearing loss, and language development in children with cleft palate. The objective of this study was to address the effectiveness of ventilation tube insertion (VTI) for OME in children with cleft palate.

METHODS

A dual review process was used to assess eligible studies drawn from PubMed, Medline via Ovid, Cumulative Index to Nursing and Allied Health Literature, Cochrane Library, and reference lists between 1948 and November 2013. Potentially relevant papers were selected according to the full text of the articles. Relevant data were extracted onto a data extraction sheet.

RESULTS

Nine high- or moderate-quality cohort studies were included in this study. VTI was administered in 38% to 53% of the OME cases, and more severe cases appeared more likely to undergo VTI. Compared with conservative forms of management (eg, watchful waiting), VTI has been shown to be beneficial to the recovery of hearing in children with cleft palate and OME. A growing body of evidence demonstrates the benefits of VTI in the development of speech and language in children with cleft palate and OME. These children face a higher risk of complications than those undergoing conservative treatments, the most common of which are eardrum retraction and tympanosclerosis, with an incidence of ∼ 11% to 37%.

CONCLUSIONS

This review provides evidence-based information related to the selection of treatment for OME in children with cleft palate. Additional randomized controlled trials are required to obtain bias-resistant evidence capable of reliably guiding treatment decisions. The conclusions in this review are based on underpowered cohort studies and very-low-strength evidence.

The protective effect of adenoidectomy on pediatric tympanostomy tube re-insertions: a population-based birth cohort study

OBJECTIVES

Adenoidectomy in conjunction with tympanostomy tube insertion for treating pediatric otitis media with effusion and recurrent acute otitis media has been debated for decades. Practice differed surgeon from surgeon. This study used population-based data to determine the protective effect of adenoidectomy in preventing tympanostomy tube re-insertion and tried to provide more evidence based information for surgeons when they do decision making.

STUDY DESIGN

Retrospective birth cohort study.

METHODS

This study used the National Health Insurance Research Database for the period 2000-2009 in Taiwan. The tube reinsertion rate and time to tube re-insertion among children who received tympanostomy tubes with or without adenoidectomy were compared. Age stratification analysis was also done to explore the effects of age.

RESULTS

Adenoidectomy showed protective effects on preventing tube re-insertion compared to tympanostomy tubes alone in children who needed tubes for the first time (tube re-insertion rate 9% versus 5.1%, p = 0.002 and longer time to re-insertions, p = 0.01), especially those aged over 4 years when they had their first tube surgery. After controlling the effect of age, adenoidectomy reduced the rate of re-insertion by 40% compared to tympanostomy tubes alone (aHR: 0.60; 95% CI: 0.41-0.89). However, the protective effect of conjunction adenoidectomy was not obvious among children with a second tympanostomy tube insertion. Children who needed their first tube surgery at the age 2-4 years were most prone to have tube re-insertions, followed by the age group of 4-6 years.

CONCLUSIONS

Adenoidectomy has protective effect in preventing tympanostomy tube re-insertions compared to tympanostomy tubes alone, especially for children older than 4 years old and who needed tubes for the first time. Nonetheless, clinicians should still weigh the pros and cons of the procedure for their pediatric patients.

Otitis media with effusion in children with cleft lip and palate: a narrative review

OBJECTIVE

Repair surgery of cleft lip and palate (CLP) can produce satisfactory cosmetic results but the problem of recurrent otitis media with effusion (OME) secondary to CLP may persist. This can cause long-term hearing loss and affect linguistic, academic, and personal development. The aim of this review is to provide the most recent information regarding OME in children with CLP.

METHODS

All papers referring to children with CLP and OME were identified from searches in Medline, PubMed, Cochrane Library, and Web of Science. Abstracts were read and relevant papers were obtained. Additional studies were obtained from the references of the selected articles.

RESULTS

Both current and previous research on OME in children with CLP focused on the controversy over treatment strategies. Evidence on the optimal treatment for OME in CLP children was lacking. Ventilation tube surgery using the same anesthetic as lip or palate procedures was not well-supported. After summarizing the literature review, a flowchart of management guidance for such patients is also recommended. Updated reviews such as this will provide clinicians and patients/parents with a valuable reference.

CONCLUSIONS

The lack of evidence on the optimal treatment for OME in children with CLP should prompt a relatively conservative approach. However, only a consensus between patients/parents and surgeons regarding the most suitable treatment strategy for OME can ensure the greatest benefit to individual patients.
