Lingual tonsils hypertrophy; a cause of obstructive sleep apnea in children after adenotonsillectomy: Operative problems and management

OBJECTIVE Although adenotonsillar hypertrophy has been reported to be the commonest cause of pediatric obstructive sleep apnea (OSA), enlargement of the lingual tonsils is increasingly being recognized as a cause, even after adenotonsillectomy. The aim of our study was to elucidate the lingual tonsils hypertrophy as a cause of pediatric OSA and also to evaluate the efficacy of lingual tonsillectomy in relieving symptoms of the disease considering the peri-operative problems and management. METHODS Sixteen children with lingual tonsils hypertrophy after adenotonsillectomy were included in the study. Computerized tomography (CT) and/or magnetic resonance imaging (MRI) were used for detection of the lesions. They underwent lingual tonsillectomy with special anesthetic care, flexible laryngoscopy and polysomnography were done pre- and post-operatively. Follow up of the patients was carried out for at least 1 year. RESULTS Three cases developed post-operative airway obstruction that is caused by tongue base edema. Complete improvement of snoring and apnea was achieved in 10 cases. Despite complete ablation of lingual tonsils, persistent snoring was detected in six cases, while apnea was detected in two cases. Downs syndrome, mucopolysaccharidoses, and obesity may be underlying factors for persistent symptoms. CONCLUSIONS Lingual tonsils hypertrophy could be the cause of obstructive sleep apnea in children after adenotonsillectomy, lingual tonsillectomy is an effective treatment for these cases, however peri-operative airway problems should be expected and can be managed safely. Persistent symptoms after lingual tonsillectomy may be due to the presence of co-morbidities such as cranio-facial deformities, obesity, and/or mucopolysaccharidoses.

Treatment of velopharyngeal insufficiency after cleft palate repair depending on the velopharyngeal closure pattern.

Velopharyngeal insufficiency (VPI) is a common problem after cleft palate repair; secondary surgery may be needed to treat this condition. Pharyngeal flap is usually selected for cases with sagittal closure pattern, and sphincter pharyngoplasty is used for cases with coronal closure pattern, whereas cases with circular closure pattern may be puzzling. The objective of this prospective study was to assess the efficacy of tailoring the surgical technique to the preoperative velopharyngeal closure (VPC) pattern and to determine the success of sphincter pharyngoplasty for cases with circular closure pattern. This study was conducted on 48 patients, who presented with postpalatoplasty VPI; the cases were classified into 3 groups according to the VPC: group A of coronal VPC was treated with sphincter pharyngoplasty, group B of sagittal VPC was treated with pharyngeal flap, and group C that exhibited circular VPC was treated with sphincter pharyngoplasty. Speech analysis, nasalance score, and nasopharyngoscopic data were recorded preoperatively and 6 months postoperatively. Also, snoring and sleep apnea were assessed. There were no significant differences between the groups regarding the speech, nasometric, and nasopharyngoscopic data. Although snoring was significantly higher after pharyngeal flap, there was no significant difference regarding apnea. Selection of the surgical procedure depending on the type of preoperative VPC pattern for treatment of postpalatoplasty VPI is an appropriate method. In case of circular closure pattern, sphincter pharyngoplasty is the operation of choice as it has a lower incidence of postoperative snoring than pharyngeal flap.

Epstein–Barr virus infection as a cause of cervical lymphadenopathy in children

OBJECTIVE Cervical lymphadenopathy is a common pediatric problem; reactive hyperplasia, specific infective agents, and malignancy are mainly the differential diagnosis. The aim of our study was to detect the prevalence of Epstein-Barr virus infection among children who complained of cervical lymphadenopathy and also to evaluate the clinical manifestations of the disease in pediatric patients. METHODS One hundred and sixty children presented with cervical lymphadenopathy were subjected to Epstein-Barr Virus (EBV) serology testing. Cases that showed positivity to heterophile antibody test, and/or EBV-specific antibodies; IgM against viral capsid antigen (VCA-IgM) and IgG against viral capsid antigen (VCA-IgG) were evaluated clinically for manifestations of the disease. RESULTS Twenty-four cases (15%) showed positivity to EBV serology, all of them had posterior cervical lymph nodes enlargement, 70.8% had fever, 66.6% had tonsillo-pharyngitis, 58.3% had splenomegaly, 25% had hepatomegaly, 41.6% had generalized lymphadenopathy, while skin rash was detected in 12.5%, and both palatal petechiae and palpebral edema were detected in 8.3%. CONCLUSIONS EBV infection is not a rare cause of cervical lymphadenopathy in children. Posterior cervical lymphadenopathy in pediatric age group may represent a password for suspicion of EBV infection, while other clinical manifestations of the disease may include hepato-splenomegaly, skin rash, palpebral edema and palatal petechiae.

Nodular fasciitis of the external auditory canal in six Egyptian children

OBJECTIVE Nodular fasciitis of external auditory canal may mimic a malignant tumor due to its progressive course, so it was the aim of this study to focus on a new etiology for aural masses to avoid unnecessary aggressive treatment. STUDY DESIGN Retrospective study on six children presented with aural masses that were diagnosed pathologically to have nodular fasciitis. METHODS Presentation of the cases clinically, radiologically and pathologically was carried out. Surgical excision of the lesions was done through the external canal with follow up of the cases for 1 year. RESULTS Recurrence was detected in two cases, one after 2 months and the other after 4 months. Re-excision was carried out without recurrence till the end of the follow up period. CONCLUSIONS Proper diagnosis of this lesion is mandatory to avoid aggressive treatment (radical surgery and/or radiotherapy) as the disease has favorable prognosis with local excision.

Closure of anterior post-palatoplasty fistula using superior lip myomucosal flap

OBJECTIVE (a) Surgical repair of palatal fistulas are technically difficult due to excessive tissue fibrosis with high failure rate. (b) The aim of this study is to evaluate the efficacy of closure of anterior palatal fistula using myomucosal superior lip flap. METHODS 33 cases with anterior palatal fistulas after cleft palate repair were subjected to closure in two-layers, the first is the oral mucoperiosteum hinge flap to reconstruct the nasal side and the second is a myomucosal flap from the inner surface of the superior lip to reconstruct the oral side. Follow up was carried out for 12 months. RESULTS The fistulas were completely closed in 30 cases (91%) and partially closed in 3 cases (9%) due to necrosis of the tip of the flap. CONCLUSIONS Closure of anterior palatal fistula by the use of superior lip myomucosal flap is a useful method with high success rate and no morbidity.

Repair of submucous cleft palate with Furlow palatoplasty

OBJECTIVE Submucous cleft palate is a congenital anomaly caused by abnormal insertion of the levator veli palatini muscles to the posterior border of the hard palate, normally these muscles unite together to form the levator sling. Velopharyngeal insufficiency (VPI) may occur in about 10% of cases, our previous treatment protocol was pharyngeal flap that may result in obstructive breathing. Furlow technique seems to be a more physiologic solution as it reconstructs the levator sling. The aim of this study was to determine the efficacy of Furlow palatoplasty in treatment of submucous cleft palate cases presented with VPI. METHODS This prospective study was conducted on 15 children with symptomatic submucous cleft palate. All cases were treated by Furlow double opposing Z-plasty technique for repositioning of levator muscles, preoperative and postoperative speech evaluation was done using auditory perceptual assessment and nasometry, while velopharyngeal closure was assessed with flexible nasopharyngoscopy. RESULTS Significant improvement of speech and overall nasalance score were achieved. Flexible nasopharyngoscopy showed complete velopharyngeal closure of 13 cases (86.7%), while one case needed secondary pharyngoplasty for correction of residual VPI and the parents of the other case refused secondary surgery as the speech improvement of their child was satisfactory. CONCLUSIONS Furlow palatoplasty technique is an effective method in treatment of VPI in cases of submucous cleft palate as it has high success rate with no morbidity.

Treatment of persistent post-adenoidectomy velopharyngeal insufficiency by sphincter pharyngoplasty

OBJECTIVE Persistent hypernasality after adenoidectomy is an infrequent problem in children with normal palate. However if it happened, it can render a childs speech unintelligible resulting in serious affection of social life. We aimed in this study to identify the causes of persistent post-adenoidectomy velopharyngeal insufficiency and to assess the efficacy of sphincter pharyngoplasty in the treatment of such problem. METHODS This study was conducted on 18 patients complained of hypernasal speech following removal of their adenoids after variable periods of failed expected spontaneous improvement. Their hypernasality was rated as being mild, moderate and severe, all cases were subjected to conservative treatment in the form of speech therapy for 3 months to correct the problem, and patients that did not respond to speech therapy were subjected to surgical intervention in the form of sphincter pharyngoplasty. Velopharyngeal closure was assessed using flexible nasopharyngoscopy, while speech was assessed using auditory perceptual assessment and nasometry. RESULTS Hypernasality was mild in 9 cases, moderate in 7 cases and severe in 2 cases. Flexible nasopharyngoscopy showed occult submucous cleft in 5 cases, short palate in 2 cases, and deep nasopharynx in 3 cases. Speech improvement was achieved in 8 cases after completion of speech therapy program (all had mild hypernasality with no anatomical palatal defects). Ten patients that had palatal defects were subjected to sphincter pharyngoplasty, 8 of them showed complete recovery, while 2 cases with severe hypernasality showed partial improvement of their speech. CONCLUSIONS Persistent post-adenoidectomy velopharyngeal insufficiency may be due to anatomical abnormalities of the palate such as an occult submucous cleft, short palate or deep nasopharynx; such conditions may be overlooked during the preoperative preparation for adenoid removal. Speech therapy is an effective method in mild hypernasality especially if there is no anatomical abnormality, while surgical correction is usually needed in moderate and severe cases, and sphincter pharyngoplasty is a useful choice for those patients.

Furlow technique for treatment of soft palate fistula.

OBJECTIVE Fistula of the palate is a common complication of palatoplasty, it leads to nasal regurgitation of fluids and hypernasality of speech. Its treatment is technically difficult due to paucity and fibrosis of palatal tissues. The aim of this study was to evaluate the efficacy of closure of soft palate fistula by using Furlow double opposing Z-palatoplasty. METHODS Nineteen patients were subjected for repair of their soft palate fistulas using Furlow Z-plasty. Pre and postoperative speech analysis using auditory perceptual assessment, measurement of nasalance score using nasometric assessment, and measurement of velar movement using flexible nasopharyngoscopy were done. RESULTS All cases showed complete closure of their fistulas at first attempt, with no operative or postoperative complications. Recurrence was not recorded in any case after a follow up period of at least 12 months. Significant improvement of speech quality and nasalance score was achieved. Flexible nasopharyngoscopy showed postoperative increase in velar movement which was not significant relative to the preoperative records. CONCLUSIONS Treatment of soft palate fistula by using Furlow technique is an effective method as a primary treatment with a high success rate and a good functional outcome.

The effect of treatment of nasal and sinus diseases on the success rate of palatal surgery for obstructive sleep apnea

Objective Many patients with obstructive sleep apnea (OSA) have coexisting nasal and sinus problems. In the absence of major anatomical abnormalities, these problems may be overlooked, hence jeopardizing the success rate of palatal surgery. Our objective was to identify the effect of medical management of nasal and sinus diseases on the success rate of palatal surgery in mild to moderate cases of OSA. Methodology This prospective study included 28 patients divided in two groups; group A was treated medically with antibiotics and local steroids before palatal surgeries, whereas group B was not treated medically before palatal surgeries. Assessment was made preoperatively and postoperatively using polysomnography. Results Group A showed more improvement in the apnea hypopnea index than group B. Conclusion Management of nasal and sinus problems improves the results of palatal surgery in cases of mild to moderate OSA.
