[Surgical treatment of benign and malignant lip tumors].

Benign tumors of the lips are resected aiming the least visible scarring. In cases of malignant tumors spreading on the surface of the lower lip we succeeded reconstructing it after complete excision of vermillion using tongue flaps. This was performed in two stages. The Meyer technique is to be preferred from functional as well as from esthetic point of view in cases where the tumor has required medium or subtotal excision of the lower lip. In tumors of the upper lip it may be used the other way round. Larger lip defects have to be managed by major regional flaps. Some examples are demonstrated.

[Diagnosis and therapy of fibromatosis in head and neck region (author's transl)].

Fibromatosis is a heterogenous group of soft tissue neoplasias, only some forms of which occur in the head and neck region. In the pathological classification it takes place between the fibroma and fibrosarcoma. With nodular fasciitis, it's subspecies myositis proliferans and aggressive fibromatosis exist differential diagnostic difficulties, especially as it's difficult to exclude fibrosarcoma. The benign myositis proliferans gives an impression of a malignant process by it's rapid proliferation, cell-polymorphia and high mitotic activity. The monomorphous histological picture and the slower proliferation of the aggressive fibromatosis, however can simulate a benign tumor, although thought to be semimalignant. 3-case-reports point out these characteristics. Complete excision is the therapy advised for all fibromatosis. In aggressive fibromatosis a large enough healthy area is the best condition to prevent recidives.

[Possibilities of reconstruction by de-epithelization (author's transl)].

By definition de-epithelization is a technique by which a graft or a flap is thinned out of the split thickness or full thickness skin layer. The underlying fat tissue is thus covered more or less by corium only. The indications for this procedure are as follows: 1. A subcutaneous defect. 2. Resurfacing defects in a cavity (for example in the pharynx) 3. Subcutaneous implantation of a flap pedicle. The advantages of de-epithelization are: 1. Widening the scope of surgical technique. 2. In many cases second surgery can be avoided. 3. The way from the donor to the recipient site is shorter. 4. A large regional flap can be used not only for reconstruction of the superficial defect but also for subcutaneous filling of a hole. Possible complications are disturbances in the nutrition of the flap and formation of subcutaneous cysts and fistulas which may lead to infections. It is obvious that careful assessment of the indication and precise technique performance are mandatory. Out of 221 flap procedures done in our department since February 1979 we used the de-epithelization technique in 7 cases (3.2%).

[Experiences with fibrinogen glue in ENT surgery (author's transl)].

Detailed informations are given about the application technique of a biological tissue adhesive based on fibrinogen clotting after a review about its development and the possibilities of application till now. From experiences in over 50 cases the author found good results by using the Human Fibrin adhesive in the ENT-surgery, especially in the surgery of the middle ear, the surgery of the nose, in plastic and plastic-reconstructive surgery, the treatment of fractures of the skull base in the area of the rhino- and otobasis, especially of the sphenoidal sinus, the covering of defects of the oral mucosa and finally to compensate outline defects in the facial area.

[Intracranial-intratemporal anastomosis of the facial nerve (author's transl)].

Using the microsurgical technique during the exstripation of the acustic neuroma in the otosurgical as well as neurosurgical approach of the procedure, it was possibel to achieve not only a considerable drop in the mortality rate, but also a preservation of the facial nerve. Our technique of intracranial/intratemporal anastomosis allow in cases with deep defects of the facial nerve in the cerebellopontine angle a relatively reliable rehabilitation of the nerve at the time of a tumor resection. The success is based on the teamwork between ENT- and Neurosurgeons. 8 patients were operated until now. In all cases the satisfactory return of the face motoric has been noted within 3/4-11/2 years after the operation.

[Facial neuralgia after Caldwell-Luc-Operation - Prophylaxis and therapy].

The postoperative neuralgia occurring after Caldwell-Luc-Operation is a common complication. It is important that the consequent surgery on the maxillary sinus does not make a preexisting neuralgia worse. On the other hand the occurrence of the postoperative pain-syndrom should be avoided. There are several possibilities in order to achieve this aim: 1. A precise choice of surgery and correct indication in every case. 2. Surgical diagnosis and therapy should go hand in hand according to the individual case. The operative technique in order to avoid the postoperative painsyndrom after Caldwell-Luc-Operation as well as the microsurgical neurolysis of the infraorbital nerve as a therapy of the neuralgia following a procedure has been discussed.

[Problems of laryngeal reconstruction following perichondritis of the larynx (author's transl)].

The surgical reconstruction of the larynx following laryngeal perichondritis is an uncommonly published subject. Three cases with special problems are presented. The main points of management to be remembered are that: 1. the complete removal of all necrotic tissue is essential for the success of surgical rehabilitation; 2. the restoration of respiration, deglutition and phonation can be achieved with use of regional skin and composite skin and cartilage flaps.

[The width of the internal auditory meatus in Bell's palsy. A radiological-tomographical study (author's transl)].

44 patients with ischemic facial paralysis were studied and tomograms made of both petrous bones. An attempt was made to establish the normal averages of various portions of the internal auditory meatus (fundus, middle, porus) from frontal projections. In addition, a comparison of each portion of the internal auditory meatus was made between diseased and healthy sides. Of patients studied, one third showed a narrowing of the internal auditory meatus on the involved side. A correlation between narrowing of the bony internal auditory meatus and the occurrence of an ischemic facial paralysis could not be established. However, such cannot be totally excluded as a contributing factor in the origin of a Bell's palsy.

[Anaesthesiological and ENT surgical aspects in long operations (author's transl)].

In ENT surgery due to the differential anatomy of the operation area, radical tumour surgery, necessary plastic surgery and covering of resulting defects, plus efforts in maintenance and reconstruction of important functions the resulting operations are frequently lengthy. In 27 patients whose operations required longer as 10 hours the problems of anaesthesia and operation were analysed and discussion from various angles. With close teamwork between surgeon and anaestheist in the planning and carrying out of such procedures and in the postoperative care it is possible to eliminate higher risks due to the prolonged operation time. The perioperative mortality rate within a time period of 4 weeks was in our case 0%.

[The reconstruction of the hypopharynx and the cervical esophagus (author's transl)].

Since 1973 16 reconstructions of the hypopharynx and cervical esophagus were performed. The restoration of swallowing was achieved in 7 cases after partial resection of the pharynx, 9 times after total laryngo-pharyngectomy and twice after laryngo-pharyngo-esophagectomy. The indication for surgery and criteria for the surgical methods to be applied are discussed. It is possible to combine the reconstruction of the pharynx with building up a neoglottis with Staffieri's technique for restoring voice function. As a one stage procedure to the hypopharynx and cervical esophagus after total laryngo-pharyngectomy the methods of Loré as well as the reconstructive techniques using regional flapes are useful. The larynx-hypopharynx-esophagusresection of Ong and Lee (1960) whould be prefered if the rumour involves the orifice of the esophagus, because an extensive submucosal growth of the carcinoma is to be expected. A two stage procedure is preferred when recurrences of cancer especially after x-ray therapy have to be treated, or a bilateral radical neck-dissection has to be done. This concept offers smaller risks and is finally also faster. A method is demonstrated using a bridge flap for the protection of the carotid artery and the reconstruction of the posterior wall of the pharynx using a deltopectoral flap for rebuilding the lateral and the anterior walls of the pharynx.

Therapeutic endoscopy of the paranasal sinuses.

This paper is mainly concerned with describing and demonstrating the technique of paranasal endoscopies--maxillary, frontal, sphenoidal--, illustrated by diagrams. The improvement of technique in diagnosis and therapy of the paranasal sinuses has proved essentially successful. Indications for therapeutic endoscopy of paranasal sinuses are: 1. Purulent sinusitis. 2. Polypous and purulent sinusitis in children. 3. The so-called "mucosinus". 4. Removal of solitary cysts. 5. Removal of tooth fillings and roots. The different procedures are described.
