Speech Outcome After partial adenoidectomy In Patients With Risk Of Hypernasality

Partial Adenoidectomy in Patients With Palatal Abnormalities.

Velopharyngeal insufficiency is a feared complication of adenoidectomies in patients with palatal abnormalities. Thus, the benefits of adenoidectomy in this population are less understood. The techniques of partial adenoidectomy aim to preserve velopharyngeal closure while sufficiently debulking the nasal airway to ameliorate obstruction and snoring. Systematic review of online databases using a combination of search terms including "cleft palate," "submucosal cleft palate," "short palate," "adenoidectomy," "partial adenoidectomy," "subtotal adenoidectomy," and "powered adenoidectomy." Two independent reviewers assessed the eligibility of each study based on predefined inclusion criteria. From 323 studies identified, 8 were included. All were retrospective case series, except 1 prospective study. Study period ranged from 1.1 to 14 years (median 7.5 years). There were 172 patients with a cleft palate (n = 80), submucous cleft palate (n = 67) or another defined palatal abnormality [short soft palate (n = 14), bifid uvula (n = 4), questionable palatal mobility (n = 4) or incomplete CP (n = 3)] identified. Mean age was 5.5 years and just over half were male (58%). Nearly all patients showed improvement in nasal airway obstruction and snoring. The pooled risk for velopharyngeal insufficiency across all studies was 2 out of 122, which approximates to 1.6% of patients. There were very few complications. This is the first systematic review of partial adenoidectomy in patients with palatal abnormalities. Sub-total adenoidectomy in patients with submucosal cleft palate or repaired cleft palate appears to be a safe and efficacious procedure. There is; however, a need for prospective data collection using a standardized technique in large patient series required to properly assess outcomes.

Role of endoscopic guided partial adenoidectomy in avoiding open nasality

ObjectivesAssess the effects of endoscopic guided partial adenoidectomy on resonance of speech in patients with poor palatal mobility and evaluate its role in avoiding postoperative open nasality. Materials and methodsThis study was a prospective randomized trial conducted in one year duration. A total of 40 patients were assessed for eligibility; 24 patients were excluded as they did not meet the inclusion criteria. Two patients out of the eligible sixteen refused surgery. Inclusion criteria: 1-patient complaining of snoring, nasal obstruction and nasal discharge, all of which were caused by adenoid. 2-Poor palatal mobility on endoscopic examination. Exclusion criteria: any neurological deficit, muscular disorder or structural defects of the palate. All eligible patients had undergone partial adenoidectomy. Speech was evaluated preoperative and postoperative. ResultsThe study group had definite poor palatal mobility on endoscopic examination and lateral videofluroscopy. Endoscopic guided partial adenoidectomy has been done to all 14 patients. Postoperative evaluation showed marked relieving of symptoms such as nasal obstruction, discharge and mouth breathing with successfully maintaining the velopharyngeal competence but there was no complete relieving of closed nasality. ConclusionThere is necessity to screen potential candidates for adenoidectomy in order to prevent postoperative velopharyngeal dysfunction. Nasoendoscopy and lateral videofluroscopy have been useful to examine the palatal mobility, palatal length, depth of the pharynx and to exclude possible occult cleft palate. Partial adenoidectomy should be taken into consideration for risky patients. Satisfactory results were obtained as regards relieving nasal symptoms and maintaining velopharyngeal competence but didn’t improve quite fully the closed nasality.

Trans-oral endoscopic partial adenoidectomy does not worsen the speech after cleft palate repair

IntroductionAdenoid hypertrophy may play a role in velopharyngeal closure especially in patients with palatal abnormality; adenoidectomy may lead to velopharyngeal insufficiency and hyper nasal speech. Patients with cleft palate even after repair should not undergo adenoidectomy unless absolutely needed, and in such situations, conservative or partial adenoidectomy is performed to avoid the occurrence of velopharyngeal insufficiency. Trans-oral endoscopic adenoidectomy enables the surgeon to inspect the velopharyngeal valve during the procedure. ObjectiveThe aim of this study was to assess the effect of transoral endoscopic partial adenoidectomy on the speech of children with repaired cleft palate. MethodsTwenty children with repaired cleft palate underwent transoral endoscopic partial adenoidectomy to relieve their airway obstruction. The procedure was completely visualized with the use of a 70° 4mm nasal endoscope; the upper part of the adenoid was removed using adenoid curette and St. Claire Thompson forceps, while the lower part was retained to maintain the velopharyngeal competence. Preoperative and postoperative evaluation of speech was performed, subjectively by auditory perceptual assessment, and objectively by nasometric assessment. ResultsSpeech was not adversely affected after surgery. The difference between preoperative and postoperative auditory perceptual assessment and nasalance scores for nasal and oral sentences was insignificant (p=0.231, 0.442, 0.118 respectively). ConclusionsTransoral endoscopic partial adenoidectomy is a safe method; it does not worsen the speech of repaired cleft palate patients. It enables the surgeon to strictly inspect the velopharyngeal valve during the procedure with better determination of the adenoidal part that may contribute in velopharyngeal closure.

Powered instrumentation for transnasal endoscopic partial adenoidectomy in children with submucosal cleft palate

ObjectivesPartial adenoidectomy is the selective removal of the obstructing part of adenoid tissue, thus relieves obstruction symptoms and preserves the velopharyngeal valve action. Patients with palatal dysfunction are candidates for the technique. This study describes the use of microdebrider, transnasally (guided by the nasal endoscope) to perform partial adenoidectomy in patients with submucosal cleft palate, who presented with adenoidal hypertrophy and also it discusses its effects on nasal obstruction and speech. Subjects and methodsThis prospective study was carried out on twenty-three submucosal cleft palate patients who were referred to the ORL-HN department; Zagazig University Hospitals complaining of respiratory obstruction and sleep disturbances due to adenoids hypertrophy. After preoperative nasoendoscopic and speech evaluation, transnasal endoscopic, power-assisted partial adenoidectomy was done for all patients. All patients were followed up at regular visits including nasoendoscopy and speech evaluation. ResultsThe procedure insured fast, safe, reliable, under vision and well controlled steps. Intraoperatively no major complications were recorded. During follow up, nasal obstruction and respiratory obstruction symptoms were improved. Speech outcome results were reported. ConclusionThe study demonstrates the feasibility of using the microdebrider for performing transnasal partial adenoidectomy (under endoscopic guidance). The procedure is precise, rapid, safe and well-tolerated with the advantage of direct visualization of a traditionally difficult-to-expose area. The study reported improvement of respiratory obstruction symptoms with good speech results.

Management of sleep apnea in the cleft population

Obstructive sleep apnea is prevalent in children with facial clefts. As there are increasing concerns that sleep disordered breathing and obstructive sleep apnea may lead to cognitive difficulties, it is imperative that the otolaryngologist and cleft surgeon be aware of the concerns for sleep disorders and implement appropriate interventions for the management. Micrognathia associated with Robin Sequence has long been understood to have significant potential for sleep apnea. Positioning, nasopharyngeal airway, tongue-lip adhesion and mandibular distraction have been used to improve the breathing in this set of children. Screened by symptoms, a large proportion of children with clefts will have a positive sleep study. Syndromic children seem to be more prone to this, even though nonsyndromic children are also at risk. Children who have had secondary management of velopharyngeal insufficiency with pharyngeal flap and sphincter pharyngoplasty seem to be at greater risk of sleep disorder. Specific directed therapies should provide the optimum results for the correction including tonsillectomy with partial adenoidectomy, revision pharyngoplasty, maxillary advancement and continuous positive airway pressure for sleep. Awareness of the risk of sleep disorders and the possible treatments in children with cleft deformities is very important for the otolaryngologist.

The effectiveness of tonsillectomy and partial adenoidectomy on obstructive sleep apnea in cleft palate patients

The most common cause of pediatric obstructive sleep apnea (OSA) is adenotonsillar hypertrophy (ATH). In cleft palate patients, however, the obstructive effects of ATH are more severe due to narrow airways. The aim of this study was to assess the effectiveness of tonsillectomy and/or partial adenoidectomy on OSA in cleft palate patients. Case series. Tonsillectomy and/or partial adenoidectomy was performed in 17 repaired cleft palate patients with tonsillar and/or adenoid hypertrophy and OSA. Apnea/hypopnea (A/H) index and minimum O(2) saturation were measured before and after surgery. In addition, because these patients are vulnerable to speech impairment after pharyngeal surgery, auditory perceptual assessment (APA) and nasometric assessment of speech were performed. The mean preoperative A/H index was 17.6 ± 3.9, and the mean preoperative minimum O(2) saturation was 88.7 ± 1.5%. Both parameters improved postoperatively, to 1.9 ± 2.3 and 93.7 ± 1.5% respectively, and the changes were significant (P < 0.001). In 12 cases (70.6%), A/H indexes were normalized following surgery. Associated comorbidities such as retrognathia and narrow pharyngeal airways may underlie incomplete recovery in some cases. There were no significant postoperative changes in APA and nasalance scores. In most cases, tonsillectomy and/or partial adenoidectomy is an effective method for treatment of OSA in repaired cleft palate patients presenting with tonsillar and/or adenoid hypertrophy. However, some cases may need further procedures to relieve airway obstruction due to associated comorbidities.

Técnicas actuales de cirugía adenoamigdalar en los trastornos respiratorios del sueño de los niños

In recent years, consolidation of tonsillar hypertrophy as the principal surgical procedure has led to the emergence of new techniques. Most aim to reduce volume (tonsillectomy or tonsil reduction). These techniques have considerably decreased intra- and postoperative hemorrhages and pain intensity. The present article describes the mechanisms and the advantages and disadvantages of the various techniques, including electro-dissection using electrical scalpels, reduction using a microdebrider, ultrasonic scalpel, radiofrequency (with its different variations) and CO 2 laser. When techniques that reduce tonsil volume are used, the possibility of recurrence of the tonsillar hypertrophy is high if less than 85% of the tonsil is removed. There is also a considerable possibility of infection of the remaining tonsils, whichever technique is used, and therefore these techniques are not valid in the case of repetitive tonsillitis. Recently, alternatives to classical adenoidectomy using adenoid curette have also appeared. Bleeding can be minimized by using a microdebrider, radiofrequency or a blood coagulator. We also discuss the concept of partial adenoidectomy, which is preferred in patients at risk of velopharyngeal insufficiency.

Partial adenoidectomy by suction diathermy in children with cleft palate, to avoid velopharyngeal insufficiency

Objectives Adenoidectomy is indicated for the relief of paediatric nasal obstruction, sleep-disordered breathing and otitis media with effusion (OME). Velopharyngeal insufficiency (VPI) is a rare complication. The main risk factor is the presence of pre-existing velopharyngeal closure-impaired mechanisms, including submucosal or overt cleft palate. Despite possible benefits, adenoidectomy is frequently withheld in such children to avoid VPI. This study aims to demonstrate the efficacy and safety of partial adenoidectomy using suction diathermy in children who previously underwent overt cleft palate repair during infancy, to allow selective resection of tissue and symptom resolution without producing VPI. Methods Since 1994, 18 patients with previously corrected overt cleft palate have undergone partial adenoidectomy at this centre, for the treatment of nasal obstruction or sleep-disordered breathing, with or without OME. Three had existing VPI following their cleft correction surgery. Selective resection of the adenoid was performed transorally under indirect vision, using a malleable suction coagulator. This allowed exposure of the posterior choanae, leaving the remaining adenoid bulk intact. Results Patients were followed up at 4 weeks, and subsequently at regular intervals (total follow up 30–180 months, median 92 months), including perceptual speech assessment in all cases. All demonstrated symptomatic improvement with respect to the original indications for surgery. None developed worsening hypernasal speech or other features of VPI, and there were no cases of symptomatic adenoidal re-growth. Conclusions Partial adenoidectomy, employing a variety of methods, has been used successfully in children with submucosal cleft palate. This study demonstrates the safe and effective use of suction diathermy to enable partial adenoidectomy in children who have previously undergone surgical correction of overt cleft palate, allowing symptom resolution without producing VPI.

Revision adenoidectomy—A retrospective study

Adenoid "re-growth" is a poorly understood phenomenon. While parents often express concerns regarding the potential for adenoid "re-growth", little information exists in the literature about its incidence and causation. To establish the incidence and possible contributing factors leading to adenoid re-growth in children. Retrospective case series review. Tertiary care children's hospital. The charts of 106 patients who underwent revision adenoidectomy between 1995 and 2006 were reviewed. Thirty-four patients were excluded because the primary adenoidectomy was performed elsewhere or initially only a partial adenoidectomy was performed. In the remaining 72 patients, demographic data, clinical presentation, associated medical conditions and findings at surgery were studied. During the 11-year study period. 13,005 adenoidectomies or adenotonsillectomies were performed; 72/13,005 (0.55%) underwent revision adenoidectomy. The mean (+/-S.D.) age at presentation for primary adenoidectomy was 3.68+/-2.9 and 7.69+/-4.04 years for secondary ("revision") adenoidectomy with an average time interval of 4.3 years between surgeries. Age at initial adenoidectomy was not a significant factor in predicting revision adenoid surgery. 29/72 (40%) underwent a reflux work up including scintiscan with gastric emptying, 24h pH probe, or laryngoscopy. 28/29 (96%) were diagnosed with reflux. At least 15/72 (21%) were reported to have symptoms consistent with adenoid re-growth which were found to be caused by tubal tonsil hyperplasia. Revision adenoidectomy rarely needs to be performed. Tubal tonsillar hyperplasia, as opposed to re-growth of residual adenoid tissue previously removed, accounts for some cases. Extraesophageal reflux is a possible cause in some and requires further study.

Sleep Disordered Breathing and Obstructive Sleep Apnea in the Cleft Population

Children with cleft deformities have the tendency for multilevel airway obstruction. The incidence of sleep disordered breathing (SDB) in this population has not been well studied. This study attempts to describe the high incidence and the results of intervention. A three-year retrospective chart review by a tertiary cleft and craniofacial team. The symptoms of sleep disordered breathing and polysomnographic data were reviewed and analyzed using descriptive statistics and multivariate analysis. Of the 539 children seen during the period, 120 (22%) had symptoms suggestive of SDB. Twenty-four of them had a tonsillectomy with or without partial adenoidectomy without polysomnogram (PSG). Sixty-nine (57%) had a PSG, and 28 (40%) had a follow-up PSG. Syndromic children had significantly more symptoms of SDB (P < .001) and were more likely to undergo PSG (P < .05). Of those children who underwent a PSG, only six had a normal obstructive apnea-hypopnea index (OAHI) with a mean (+/-standard deviation) respiratory disturbance index (RDI) of 15.5 (+/-17.5) and OAHI of 12.05 (+/-15.57). Post intervention PSG showed significant improvement in RDI (P = .048) and OAHI (P = .012) using a single-tailed Wilcoxan analysis. Unfortunately, most of these children still had significant sleep apnea. There was also a high percentage of children with periodic leg motion syndrome (24.7%), some of whom also had OSA. There is a high incidence of SDB and definable OSA in the cleft population. Though there is a statistically significant improvement after intervention, some were not cured. Sleep disturbance and OSA is likely under-reported and treated in the cleft population. PSG should be done more frequently, and post intervention PSG should be strongly considered.

小児ＯＳＡＳに対するマイクロデブリッダー併用手術

Obstructive sleep apnea syndrome (OSAS) in youth causes various sequelae—life-threatening, body composition and school performance. Adenotonsillar surgery is beneficial for treating pediatric OSAS, however, the traditional methods pose some problems such as re-multiplication of adenoids. We performed total tonsillectomy and Power-Assisted Partial Adenoidectomy (PAPA) in 111 children for 3 years and 25 cases were examined Oxygen Desaturation Index 3% (ODI 3%) during sleep with a pulseoxymeter before and after the operation.Their ODI 3% improved significantly after surgery. No long-term complications, such as relapse of OSAS and immunodeficiency, have occurred. PAPA with total tonsillectomy is very useful for the treatment of pediatric OSAS.

Floating the uvula: An intraoperative method for detecting bifidity

A bifid uvula, midline diastasis of the palatal muscles, and notching of the posterior hard palate have classically formed a triad diagnosing submucosal clefts. The uvula has thus served as a tool for clinicians to detect the earliest signs of clefting. In this case report, we discuss how mucosal lining may be held together by mucous viscosity, making it difficult to detect notching or a grossly bifid uvula. We demonstrate a simple intraoperative technique to easily overcome this force. This paper involves a case report of an 8-year-old female undergoing an adenotonsillectomy. A previously undetected bifid uvula was found only after floating the uvula in normal saline solution. This changed our surgical approach from a complete to a partial adenoidectomy. A bifid uvula may be considered the earliest form of a cleft palate, and more importantly, it has been shown in the literature to be associated with other anomalies as submucosal cleft, hyoplastic eustachian tube orifice, and absence of the salpingopharyngeal folds. The intraoperative technique of floating the uvula helps to overcome mucous viscosity and identify an otherwise missed bifid uvula.

Endoscopic adenoidectomy in children with submucosal cleft palate

To determine the safety and effectiveness of endoscopic partial adenoidectomy for the treatment of nasal obstruction in children with submucosal cleft palate. The medical files of children with symptoms of nasal obstruction and submucosal cleft palate who underwent partial transnasal endoscopic adenoidectomy from January 1993 to December 2003 were reviewed. Operative complications, relief of nasal obstruction, presence of postoperative velopharyngeal insufficiency were recorded. There were no operative complications. All the children had relief of nasal obstruction. Velopharyngeal insufficiency was not observed during the postoperative follow-up. Endoscopic partial adenoidectomy is a safe and effective procedure for the treatment of nasal obstruction in children with submucosal cleft palate.

Endoscopic partial adenoidectomy for children with submucous cleft palate.

Children with submucous cleft palate who suffer from chronic nasal obstruction because of hypertrophic adenoids usually are not subjected to adenoidectomy because of the fear of postoperative velopharyngeal insufficiency. These patients present a therapeutic challenge because we are aware more than ever of the importance of normal nasal breathing and nocturnal respiration, especially during childhood. Our hypothesis was that transnasal endoscopic horizontal limited adenoidectomy may relieve nasal obstruction while preserving the function of the velopharyngeal valve. The objective of this study was to evaluate the efficacy of transnasal endoscopic horizontal partial adenoidectomy in patients with submucous cleft palate and adenoidal hypertrophy. Patients were either referred to the outpatient clinic of the Palate Surgery Unit (seven patients) or were patients referred to the senior author's (Y.F.) private clinic. All the patients had been operated on by this senior author (Y.F.). Ten children aged 3.5 to 13 years (six girls and four boys) with submucous cleft palate and hypertrophic adenoids were included in the study. All the patients were hyponasal and suffered nasal obstruction, loud snoring, and episodes of apnea. Endoscopic partial adenoidectomy was accomplished to open the lower third of the choanae. Nasal breathing was achieved in all the patients, and only mild snoring remained in two patients. The hyponasality disappeared and speech intelligibility normalized. Mild hypernasality developed in two patients but was still perceived as an overall improvement in speech. Transnasal endoscopic horizontal partial adenoidectomy may be an effective surgical method for relief of nasal obstruction while preserving velopharyngeal valve function in patients with submucous cleft palate who suffer from obstructive adenoids.

Powered partial adenoidectomy.

To confirm our clinical impression that the powered microdebrider is superior to curettes for performing partial adenoidectomy (removal of the superior one half to three fourths of the adenoid pad). Observational study of 100 children undergoing partial adenoidectomy with the powered microdebrider compared with 40 children undergoing conventional partial adenoidectomy with curettes. Private and public tertiary care centers. All patients younger than 20 years undergoing partial adenoidectomy at the respective institutions during the study period. Partial adenoidectomy as indicated for chronic otitis media, airway obstruction, or chronic or recurrent tonsillitis with either the powered microdebrider or curettes. Operative time (with specific quantification of the time required for tissue removal and hemostasis), blood loss, complications, and subjective ease of use. Operative time was 59% shorter for the microdebrider group (mean, 3 minutes 22 seconds; range, 1 minute 6 seconds to 12 minutes 45 seconds) than for the conventional group (mean, 8 minutes 8 seconds; range, 1 minute 2 seconds to 22 minutes 0 seconds) (P<.001). Blood loss was comparable for both groups (powered group: mean, 2.0 mL/kg; range, 0.4 to 9.4 mL/kg; conventional group: mean, 2.0 mL/kg; range, 0.3 to 6.7 mL/kg; P=.34). There were no intraoperative or postoperative complications in either group. Surgeon satisfaction with the microdebrider was high. The powered microdebrider for partial adenoidectomy is quicker and is not associated with blood loss or complications above that of conventional partial adenoidectomy. The degree of control afforded by the microdebrider technique is of utmost value in preventing complications such as velopharyngeal insufficiency, and this is now our procedure of choice.

Superior Adenoidectomy in Children with Palatal Abnormalities

When treating a child with a palatal abnormality for otitis media or a nasal obstruction, otolaryngologists often face the question of whether the benefits of adenoidectomy are worth the risk of the development of velopharyngeal insufficiency. Treatment options for these patients include a complete adenoidectomy, a partial adenoidectomy, or no surgical intervention. In this retrospective study, we describe the outcomes of 22 such patients who were treated with a superior adenoidectomy performed with a St. Clair adenoidforceps under indirect vision with a laryngeal mirror. All patients experienced a complete or near-complete resolution of their nasal obstruction, and none developed permanent velopharyngeal insufficiency. Only three patients experienced a recurrence of otitis media. Our experience suggests that superior adenoidectomy is a safe and effective procedure.

Partial adenoidectomy.

Adenoidectomy in the presence of an inadequate palate may result in velopharyngeal insufficiency. When an adenoidectomy is indicated in a child whose palate is not fully adequate, a partial adenoidectomy may be considered. Partial adenoidectomy involves removing the upper part of the adenoid for relief of nasal obstruction while leaving the lower portion of the adenoid intact to ensure velopharyngeal competence. Fifty-eight children underwent partial adenoidectomy over a 4-year period; 55 of these children had preoperative nasal obstruction; 49 had a tonsillectomy done at the same time; and 2 had had a previous T&A. The rationale for retaining the lower portion of the adenoid includes a short soft palate, decreased palatal mobility, a mild submucous cleft palate, huge tonsils pushing the palate anteriorly, and a short hard palate. The relief of nasal obstruction was excellent. There were no primary postoperative hemorrhages, and none of the 58 children developed velopharyngeal insufficiency following partial adenoidectomy.
