[Comparative rhinomanometric measurements in children with cleft palate after cleft closure with and without velopharyngoplasty].

To answer the question if a cranially based pharyngeal flap in patients with cleft palate could affect nasal breathing, 49 children were examined by active anterior rhinomanometry with and without decongestion of the nasal mucosa. All patients were between 10 and 12 years old. In 18 of them palatoplasty with a cranially based pharyngeal flap was performed at the average age of 3.5 years. The control group consisted of 21 children who had been treated with an intravelar veloplasty without any flap at the age of 11-13 months. None of the patients had any appreciable narrowing of the nasal airways. Using the U test we found no significant difference between the inspiratory breathing volume of both groups. The difference between in- and expiratory volume in each group showed no significance either while the volumes we examined before and after decongestion differed significantly. Thus, we cannot conclude that the cranially based flap affects nasal breathing in cleft palate patients compared to those without any flap.

[Facial injury caused by an umbrella spoke].

We report an unusual injury of the face caused by the spoke of an automatic telescoping umbrella that come loose when the umbrella was opened. Due to the shot-like force of the spoke, the left nostril, septum and right wall of the nasal cavity were pierced. The part with the joint penetrated into the maxillary antrum. In order to remove the spoke, wire scissors had to be used to cuff off the spoke's joint inside the surgically opened maxillary sinus.

[A contribution to the controversial discussion on a preoperative orthodontic treatment for infants with unilateral cheilognathopalatoschisis].

A longitudinal study of 39 casts of pre-operative orthodontically treated unilateral cleft lip and palate children from birth to palate operation was carried out with a special coordinate measuring technique to quantify changes in the maxilla. A significant reduction in width of the alveolar cleft was found. The anterior alveolar arch width remained constant, while the posterior region slightly increased. These results seem to justify treatment with the infant appliance. After measuring casts from 39 preoperatively treated and casts from 62 untreated patients prior to lip operation, a comparison of the mathematical average values between the two groups revealed few differences. This can be explained by referring to the original morphological findings and the different measurements during the preoperative orthodontic treatment, which lead to different changes in segment position prior to lip operation. In a cross section examination this difference could not be found. A sub-classification of the subject matter in primary and secondary clefts revealed that between both types clear differences in the resulting parameters can be observed. This leaves the question, whether the width of the cleft palate is caused by tissue deficiency or by an embedded tongue. Furthermore, how will the orthodontic appliance therapy influence the growth? A greater dislocation of the segments in secondary clefts may be expected in cases where the rest position of the tongue appears caudal. Improved measuring methods to record cleft morphology and more emphasis on the study of soft tissue reactions may help to understand the differing results after preoperative or orthodontic treatment.

[Otorhinolaryngological aspects in the rehabilitation of patients with cleft lip and cleft palate].

The author emphasizes the importance of otorhinolaryngology to the result from speech therapy, the faculty of hearing, nasal breathing and the general state of physical and mental health. In this connection, some results from hearing tests and ear-drum examinations performed in cleft patients are presented. With due regard to indication, tonsillectomy and adenotomy exert no negative effects on speech. The causes of impaired nasal breathing must be eliminated for orthodontic reasons. Consequently, a close co-operation between otorhinolaryngology and orthodontics is imperative.

[Therapy problems in sphenoethmoidal meningoceles].

After a brief survey of the forms of cranial meningoencephaloceles, the current opinions on their development, symptoms and surgical therapy, a report is given on the case of a five-year-old boy suffering from a sphenoethmoidal meningocele of the size 3 x 3 x 4 cm. There was at the same time a wide median palate cleft, obviously a consequence of the meningoencephalocele. A further finding presented by the boy was a neuroradiologically diagnosed agenesis of the Corpus callosum and a median cheiloschisis. This suggests a central development disturbance as a primary cause. The attempt to perform an intracranial occlusion of the defect of the base, which was repeated twice, was not successful. It was only by a transpalatinal-transnasal extradural intervention (reposition of the meningocele after removing the epipharyngeal mucosa, blocking of the bony defect with a perforated tantalum plate) that the removal of the meningocele was successful. The closure of the palate cleft was then made by the oral surgeon. This surgical intervention may also be considered for the treatment of the transsphenoidal meningoencephalocele, which also presents many problems.
