[Displacement of a stapes piston as a consequence of whiplash injury with head impact].

We report the case of a 60 year old patient suffering from a displacement of her stapes piston after a rear-end collision with whiplash injury. Immediately after the accident she complained hearing loss and tinnitus. During the following days, the patient developed vertigo with lateropulsion. Diagnostic tympanoscopy showed a piston dislocation with migration into the vestibulum as a result of the blunt head trauma.

[Extra-abdominal desmoid tumors. Case report and literature review].

Musculoaponeurotic fibromatosis or desmoid tumors are rare. We report the case of a 57 year old woman with a slowly growing tumor behind the sternocleidomastoid muscle, which was completely removed. Histological examination confirmed the clinical suspicion of a desmoid tumor. Desmoid tumors are aggressive, locally infiltrating, non-metastasizing tumors with a high local recurrence. Genetic, endocrine and physical factors have been implicated as causative agents. The diagnosis is made histologically, reactive fibromatosis and fibrosarcoma must be eliminated in differential diagnosis. By the combination of different radiographic techniques, it is possible to describe the tumors and differentiate between vessels, nerves and bones. The therapy of the choice is the surgical resection. Adjuvant therapy, such as x-ray treatment, chemo- and hormone therapy, are indicated when the tumor is inoperable or too extensive for surgery.

[Modified set back tongue flap: an alternative surgical approach in the reconstruction of defects of the base of the tongue].

The base of the tongue after tumor resection can be reconstructed in several ways. In addition to direct suturing of small defects, a variety of local or microvascularly anastomosed flaps have been described. The present paper is aimed at introducing a local tongue flap for the reconstruction of medium-sized defects. Six patients were treated at the hospital between 1999 and 2002 with the above technique to cover defects affecting one-half to three-fourths of the base of the tongue. One patient had secondary bleeding and the other one experienced no complications. Nutrition could be started after 7.5 days (4-12) postoperatively on average. The tracheostomy was closed at 16.2 days (12-22) on average after the initial operation. The hospitalization of the patients was 20.3 days (15-27) on average. The modified set back tongue flap is an alternative in the reconstruction of subtotal defects of the base of the tongue. Easy handling, good functional outcome in swallowing, and the low complication rate were advantageous in the present series.

[Mode-of-action of manual medicine in the cervical spine].

Manual medicine aims at diagnosing and treating different disorders of the musculoskeletal system. It is a multidisciplinary approach with special emphasis on reversible disorders of the joints, muscles and ligaments. This treatment conception includes chirotherapy, physical therapy and drug treatment. The spine, an in particular the cervical spine, is treated primarily for joint disorders characterized by a variety of symptoms (e.g.headache, vertigo, dizziness, blurred vision). Manual medicine should be an integral part of modern clinical otolaryngology.

[Tracheal ruptures in endotracheal intubation. Diagnosis and therapy].

BACKGROUND: Tracheal ruptures are most frequently the result of a blunt trauma to the thorax or of forced intubation. They represent a rare, but life-threatening complication that requires immediate help. METHODS: The resulting pneumothorax and the skin/mediastinal emphysema are the most prominent clinical signs. Injuries of the tracheobronchial tract should be diagnosed endoscopically and treated surgically immediately after the trauma. RESULTS: The present paper reports on three cases of tracheal ruptures after forced intubation which could be successfully managed by tracheostomy and subsequent reconstruction of the defects. The postoperative care of the patients is critically discussed.

[Mesenchymal chondrosarcomas of the facial skull].

A 13-year-old girl suffered from a mesenchymal chondrosarcoma of the left maxilla. The therapeutic options and the prognosis for this disease are described with respect to the currently known 72 cases in the literature. Mesenchymal chondrosarcomas are rare tumors of the bone and soft tissue. The first clinical symptom is a painless swelling of the facial skull. They occur largely in the 2nd and 3rd decades of life, preferentially in males. Radiological criteria for the identification of this type of tumor include focal ossification areas which are accompanied by non-calcified regions. Complete surgical removal of the tumor is the therapy of choice. Pre- and postoperative chemotherapy can have a beneficial effect. The final outcome of the disease is difficult to evaluate since late complications (e.g., reoccurrence and/or metastases) appear even after 20 years and only a small number of cases have been reported. At present, the 5-year survival rate is reported to be 54-82% and the 10-year rate 28-56%.

[Reconstruction of traumatic skull base defects with alloplastic, resorbable fleece].

BACKGROUND AND OBJECTIVE: Defects of the frontal skull base can be reconstructed with different types of material. Homologous material possibly involves the risk of infection and thus complicated wound healing. Therefore, alloplastic material seems to be an interesting alternative. PATIENTS/METHODS: In the present paper, we report on a series of 45 patients who underwent reconstruction of the anterior skull base. The defects were localized in different regions and had a maximum diameter of 10 cm2. Of the defects, 39 were closed via a sandwich technique and 12 via an onlay. The rhinosurgical approaches were aimed at closing the defects with Ethisorb, a resorbable collagen texture, and supporting the surgical field with a balloon catheter from below. Postoperative controls were performed after 6 weeks (endoscopy, determination of beta 2-transferrin) and 6 months (CT scans). RESULTS: All defect reconstructions were stable and tight, i.e., neither a CSF leakage nor a meningoencephalocele was found. The healing was completely normal and the endoscopic controls showed a regular mucosal lining over the defects. CONCLUSIONS: We conclude that Ethisorb is a useful alternative material in the treatment of frontal skull base defects.

[Esthetic incisions in traumatology involving the mid-face region].

For exposure of the facial bones and orbital floor, various types of incisions can be employed. For exposing the orbital rim, a subciliary incision may have the disadvantage of producing chronic edema and shortening of the lower lid. The transconjunctival approach combined with lateral canthotomy avoids an external scar and allows sufficient exposure of orbital floor and zygomatico-frontal suture line. The placements of implants and osteosynthesis are then possible. In severe midfacial trauma the authors prefer temporo-temporal incision combined with a conjunctival approach, lateral canthotomy and intraoral access to the zygomatico-maxillary area.
