Eustachian tube function in sudden hearing loss and in healthy subjects.

The relationship between sudden hearing loss and an ipsilateral patulous tube was tested in our Eustachian tube laboratory. Fifty patients suffering from sudden hearing loss were examined by the pressure chamber impedance method, giving objective data on Eustachian tube function. Results were compared to those obtained from 56 healthy volunteers in a preceding investigation. Our investigation did not show any associations between patulous tube syndrome and sudden hearing loss, as had been claimed by several authors previously. There was even indication of a decreased patency of Eustachian tube in our patients in active and passive tubal tests. We could demonstrate a high reproducibility of values obtained by our method, indicating that results are representative in healthy persons as well as in patients. In a case report the importance of objective diagnostic methods in differential diagnostics of Eustachian tube pathology is emphasized.

Relationship between tubal function, craniofacial morphology and disorder of deglutition.

26 children without hearing impairment have been examined by otolaryngologists and orthodontists. According to the tubal function test in a pressure chamber they were classifed into a group with good and poor tubal function. The E.N.T. examination was unconclusive for a possible relationship between rhinological findings, mode of breathing, sinusitis, size of tonsils, nasal airway resistance and tubal function. Adenoids proved to be a mechanical impairment for active tubal function as stated by many authors. The cephalometric analysis of lateral head films combined with a static and dynamic-functional evaluation of tongue posture revealed significant differences between children with good and poor tubal function. Subjects with a vertical craniofacial growth pattern seem to be predisposed for poor tubal function. Analysing static tongue posture in children with poor tubal function the tongue lies more retracted in a backward position. The back of the tongue is flattened in relation to the palatal arch. In children with good tubal function there is a much closer contact between the back of tongue and the hard palate. Subjects with poor tubal function have an increased incidence of abnormal deglutition combined with tongue-thrust, teeth-apart swallowing, lack of sealing off the anterior oral cavity and contraction of the circumoral musculature. In children with good tubal function one can find the somatic type of swallowing that means no contractions of the circumoral muscles, no tongue-thrust during deglutition but contact of the molars and contraction of the masseter muscle.

[Simultaneous multiple flaps in head and neck surgery (author's transl)].

We have developed several variations of the "bilobed flap" for the reconstruction of large defects of the head and neck. In so doing, we use pedicled bi- and tri-lobed flaps, transposition-rotation skin flaps or double-rotation skin flaps. Some examples are described to illustrate the technique employed.

[Bone conduction changes in secretory otitis media (author's transl)].

In serous and secretory otitis media a reduction of bone conduction frequently exists besides the loss of air conduction. In 304 audiograms of ears with serous and viscous fluid in the middle ear there was a depression of the bone conduction between 15 and 40 dB in 40%. This bone conduction loss was reversible after the aeration of the tympanic cavity. That means that we deal with a false nerve deafness in many of these cases.

Growth influence on tubal function.

The influence of growth on tubal function was studied in 26 children by means of tubal function tests in a pressure chamber and by geometric analysis of lateral cephalograms. Good tubal function coincided with mesoor brachycephalic skeletons, poor tubal function with dolichocephalic morphologic patterns. According to our results, tubal function seems to be strongly influenced by the growth processes of the skull.
