Chronische Tubendysfunktion und ihre Folgeerkrankungen bei Erwachsenen mit einseitiger Lippen-Kiefer-Gaumen-Spalte

[Eustachian tube dysfunction after cleft palate surgery : Use of the latest diagnostics]

OBJECTIVE

In patients with cleft palate, a high incidence of chronic obstructive Eustachian tube dysfunction (ETD) is assumed after surgery. Consequently, an increased rate of retracted eardrum or cholesteatoma is expected. Even though no common standard for investigating ETD is available, the development of objective tests has increased during the past 10 years. This study aimed to investigate the incidence of persisting chronic obstructive ETD in adult patients with cleft palate surgically treated in early childhood by using a combination of diagnostic tools.

METHODS

Adult participants with cleft palate repair in early childhood were invited for a follow-up examination and compared to a control group. Examination included tympanometry, tubomanometry, the Eustachian Tube Dysfunction Questionnaire (ETDQ-7), and the Eustachian Tube Score 7 (ETS-7).

RESULTS

A total of 16 adult patients were re-examined after cleft palate surgery and compared to a control group of 40 healthy individuals. Significant differences were found in the median ETS‑7 (p < 0.0001) score but not in the median ETDQ‑7 (p = 0.09) score. Only 2 of the 32 investigated ears (6%) had pathologic scores in ETS‑7 and ETDQ‑7 (p = 0.09), whereas 5 (31%) cleft palate patients showed symptoms of chronic obstructive ETD according to ETS‑7. No patient had examination findings indicating a requirement for further treatment.

CONCLUSION

By combining diagnostic tools for ETD, a lower rate of persisting obstructive ETD in adults after cleft palate surgery was found than previously reported. Successful surgical treatment of cleft palate seems to lead to physiological Eustachian tube function in long-term follow up.

High incidence of cleft palate and vomer deformities in patients with Eustachian tube dysfunction

Although the cleft palate is regarded as a contraindication for Eustachian tube ballooning, the presence of submucosal cleft palate may be overlooked while diagnosing Eustachian tube dysfunction. Therefore, we aimed to determine the incidence of the presence of a hard palate bony notch and vomer defect, which indicate the presence of submucosal cleft palate in patients with Eustachian tube dysfunction. In the Eustachian tube dysfunction group (n = 28), 4 patients (14.3%) exhibited a hard palate bony notch and a concurrent vomer defect. Three of them exhibited the presence of occult submucosal cleft palate, which had not been diagnosed previously. None of the control group (n = 39) showed any of these findings. The hard palate length of patients in the Eustachian tube dysfunction group was significantly lesser than that of those in the control group (34.2 ± 5.6 mm vs. 37.2 ± 2.1 mm, P = 0.016). Patients with Eustachian tube dysfunction have a high incidence of submucosal cleft palate and its occult variant, which are challenging to diagnose without any preexisting suspicion. Clinicians should evaluate the hard palate and vomer to exclude the presence of occult submucosal cleft palate while diagnosing Eustachian tube dysfunction.

[Two-year experience in the balloon dilatation treatment of children with persistent auditory tube dysfunction]

OBJECTIVE

Is to study the effectiveness of the of balloon dilatation of the auditory tube in children with persistent dysfunction of the auditory tube. Examination and treatment of 28 children aged 5 to 16 years with persistent dysfunction of the auditory tube was performed. To diagnose and objectify the results of the treatment, taking of complaints and medical history of the patient, examination of ENT organs, endoscopic examination of the nose, nasopharynx and otoendoscopy, functional multispiral computed tomography of the auditory tubes, audiological examination (tympanometry, tonal threshold audiometry) were performed. Treatment included balloon dilatation of the auditory tubes. In 25 (89.3%) children, upon repeated examination after 2, 6, 12 months, the clinical, radiological, and audiological parameters were normal.

[Auditory tube dysfunction in children (literature review, part 1)]

We present the review of the literature on the anatomical and physiological features of the structure of the auditory tube in children, epidemiology, etiology, and the pathogenesis of the formation of auditory tube dysfunction is presented. The first part of the article presents in more detail the structural and functional differences in the Eustachian tube in children, the classification and mechanism of the occurrence of the auditory tube dysfunction in pediatric practice.

Differences in the Tensor Veli Palatini Between Adults With and Without Cleft Palate Using High-Resolution 3-Dimensional Magnetic Resonance Imaging

OBJECTIVE

To investigate the dimensions of the tensor veli palatini (TVP) muscle in adults with and without cleft palate.

DESIGN

Prospective study.

PARTICIPANTS

There were a total of 14 adult participants, 8 noncleft and 6 with cleft palate.

METHODS

Analysis and comparison of the TVP muscle and surrounding structures was completed using 3D MRI data and Amira 5.5 Visualization Modeling software. TVP muscle volume, hamular process distance, mucosal thickness, TVP muscle length, and TVP muscle diameter were used for comparison between participant groups based upon previous research methods.

RESULTS

Mann-Whitney U tests revealed a significantly smaller ( U < .001, P = .002) TVP muscle volume in the cleft palate group (median = 536.22 mm³) compared to individuals in the non-cleft palate group (median = 895.19 mm³). The TVP muscle was also significantly shorter ( U = 1.00, P = .003) in the cleft palate group (median = 18.04 mm) versus the non-cleft palate (median = 21.18 mm). No significant differences were noted for the other measured parameters.

CONCLUSION

Significant differences in the TVP muscle volume and length among the noncleft participants found in this study may insights into the reported increased incidence of otitis media with effusion (OME) seen in the cleft population. Results from this study contribute to our understanding of the underlying anatomic differences among individuals with cleft palate.

[Diagnosis and treatment of Eustachian tube dysfunction]

The Eustachian tube protects against secretion, germs and sound pressure from the nasopharynx, it acts as a drain, and serves pressure equalization in both directions so that the ear drum and sound-conducting apparatus can vibrate optimally. The incidence of Eustachian tube dysfunction in adults is about 1%, in children almost 40%. Symptoms are often unspecific. For diagnosis, the Eustachian tube score (ETS-5) can be used in patients with a perforated ear drum, and the ETS-7 score in patients with intact ear drum. Adenoid hypertrophy is a frequent cause of obstructive tube dysfunction in children. Treatment of obstructive dysfunction includes steroid nasal sprays and regular performance of the Valsalva maneuver, as well as tube dilation with the Bielefelder balloon catheter. The patulous Eustachian tube is treated with saline nasal irrigation, estrogen-nasal ointment, and craniocervical manual therapy; causal treatments are evaluated.

Treatment of pharyngotympanic tube dysfunction

Eustachian tube dysfuntion intends to describe a variety of signs, symptoms, and physical findings that result from the impairment of ET function. A large variety of methods have been employed to assess ET function in the literature. Due to the lack of high level evidence, it is difficult to draw conclusions on the effectiveness of medical and surgical treatments. There are various medical and surgical interventions available for chronic obstructive ET dysfunction including balloon Eustachian tuboplasty (BET) and laser or microdebrider tuboplasty. Consensus on diagnostic criteria for ETD is required to define inclusion criteria of future trials. There is however emerging work with reassuring, but preliminary, results that suggest evidence for safety in the surgical management of ETD. Like many newly introduced techniques the current data remains limited to non-controlled case-series, with heterogeneous data collection methods and lacking substantial long-term outcomes. Nevertheless, short-term data provide favorable results. Current treatment options comprising BET and patulous ET surgery may be offered as a treatment possibility to selected patients.

Profile of patients with cleft palate fitted with hearing AIDS

Cleft palates cause alterations in palate and lip structures, and it may also cause hearing loss because of recurrent otitis media. The appropriate treatment is controversial. It may include the prescription of antibiotics and insertion of a ventilation tube, or even otorhinolaryngological and audiological assistance, and hearing rehabilitation, with the use of an individual sound amplifier aid (ISAA).

AIM

To characterize the profile of individuals with cleft palate and hearing loss, users of ISAA are assisted by the center of otorhinolaryngology and speech therapy of a hospital specialized in craniofacial anomalies and hearing impairment. Retrospective Study.

MATERIAL AND METHODS

Retrospective analysis of 131 charts of patients with corrected cleft palate and hearing loss, fitted with ISAA by the center abovementioned.

RESULTS

The sample (n=131) was characterized by a prevalence of females (53%), unilateral incisive transforaminal cleft (27%), presence of associated anomalies (51%), history of alterations of the middle ear (56%) and surgery intervention (56%).

CONCLUSION

The general profile of the individuals with cleft palate and hearing loss, fitted with ISAA, was characterized by the predominance of cleft lip and palate, positive history of middle ear alterations, surgery intervention and bilateral sensorineural hearing loss.

The improvement of middle ear ventilation by laser ablation of the epipharyngeal eustachian tube: a prospective study

A long-lasting dysfunction of the eustachian tube seems to be the etiologic origin for development of chronic otitis media (COM) with mesotympanic perforation, otitis media with effusion (OME), and chronic atelectasis of the middle ear. Surgical interventions in the middle ear generally treat the sequelae of the tube dysfunction but not the dysfunction itself. This prospective clinical study investigated how far fiber-guided laser ablation of the posterior half of the epipharyngeal tubal ostium led to better middle ear ventilation in the otologic disease patterns mentioned below. There were 38 adult patients included in the analysis. The patients in one group had a perforated tympanic membrane [COM before primary tympanoplasty (n = 14) or revision tympanoplasty (n = 5)]; the patients in a second group had an intact eardrum [OME resistant to therapy (n = 3), with an atelectasis of the middle ear (n = 2) or problems of pressure equalization with fast changes in ambient pressure (diving, flying) (n = 14)]. Laser ablation of the posterior half of the epipharyngeal tubal ostium was performed, generally with local anesthesia, if tubal function testing was pathologic (Valsalva maneuver, passive tube opening, tympanogram). In patients with COM the procedure was performed 8 weeks before the middle ear surgery. All patients were checked 8 weeks postoperatively and in the course of the following year. The intervention seemed to have had a positive effect on tube function in 68.4% of patients operated on (P = 0.001). In 26 of the 38 patients that had undergone operation, an improvement the results of tubal function tests could be seen in the postoperative follow-up. In the COM group the Valsalva maneuver improved in 14 of 19 patients (73.6%) (P = 0.001), and the passive tube opening improved in nine of 18 patients (50%). In the group with an intact eardrum the Valsalva maneuver improved in 13 of 18 patients (72.2%) (P = 0.001). The resulting condition remained stable after 1 year. None of the patients showed any complications as a result of the therapy. Minimally invasive shaping of the distal eustachian tube under topical anesthesia can be recommended for patients with the above-mentioned diagnoses who have pathologic middle ear ventilation. Especially prior to tympanoplasties, and especially in otologic revision procedures, where middle ear ventilation is a prerequisite for successful otologic surgery, the function of the eustachian tube can be optimized in 70% of the patients, particularly if there are pathological findings (tubal tonsil, narrow orifice of the tubal ostium, adenoids). The placement of permanent ear tubes in adults with recurrent OME can also be avoided by the procedure described. The resultant conditions remained stable for the next year. Patients with tympanic ventilation problems due to rapid pressure changes (flying, diving) can also benefit from this procedure.

Séquelles otologiques dans les fentes palatovélaires. Analyse et prise en charge

As early as in 1878, medical teams managing children born with a velopalatine cleft had noted the prevalence of middle-ear pathologies largely related to anatomic and inflammatory Eustachian tube dysfunction. The aim of this study was to describe otologic sequels related to a velopalatine cleft and to suggest an adapted management. These sequels are evolving presentations of chronic serous otitis; they worsen the functional prognosis (hypoacousia) and more rarely the vital prognosis (cerebral or infectious complications of cholesteatoma). We must stress the importance of prevention: during the initial management, by Eustachian tube rehabilitation, and by ENT (Ear, Noseand Throat) follow-up allowing to prevent these sequels and to bring hearing to normal as soon as possible, so as to support cognitive development, language skills, and sociofamilial integration of the children.
