[Simultaneous papillary carcinoma in a thyroglossal duct remnant and the thyroid gland].

BACKGROUND: In 1 % of the thyroglossal duct cysts malignant transformation is found with predomination of the papillary carcinoma (80 %). CASE REPORT: We present the case of a 51 year old man with a synchronic papillary carcinoma in a thyroglossal duct remnant and a microcarcinoma of the thyroid gland. After exstirpation of a thyroglossal duct cyst histological examination identified a papillary carcinoma. Postoperative staging uncovered enlarged lymph nodes but no abnormalities in the thyroid gland. Cervical lymphadenectomy and total thyroidectomie was performed. On histological examination a synchronic microcarcinoma of the thyroid was shown. CONCLUSION: Only 7 similar cases have been published in literature before. Because of the rare incidence no therapeutic standard could be established so far. We discuss our therapeutic approach as well as the relevant literature.

[The cartilage conserving concept of surgical tracheostomy].

BACKGROUND: Most techniques of tracheostomy include a resection or at least incision of the cartilage himself. This may result in local tracheomalacia and chondritis. METHODS/PATIENTS: We performed 48 tracheotomies (173 cases were totally performed in our in 2002 excluding laryngectomie patients) in with horizontal incision between 2 (nd) and 3 (rd) ring sparing all cartilage. The detailed technique is described and the (endoscopic controlled) follow-up data showed no complications. We called this techniques the visor-tracheostomy. RESULTS: It is shown, that a modified concept of conservating cartilage while doing tracheostomy is easy to perform without any increasing in time and costs. The most important thing is to choose the right incision range. CONCLUSIONS: It seems to us, that healing of these tracheotomies is better and secondary complications as stenosis of trachea should be less instead of the cases where Björk-flaps or simply local resection were performed.

[Two rare complications in patients with bone-anchored hearing aids].

In our program of bone-anchored hearing aids we experienced two rare complications: a child with a hearing aid fell on her head and got an intrusion of the bone-screw into the intracranial space with a fracture of tabula externa and interna. There were no further intracranial complications, no hematoma or infection. The screw was explanted immediately with oto-microsurgical instruments and diamond burrs. The site of the screw was covered with a local skin flap. There were no complications in wound healing and the child got a second implant on the other side. A patient got an infection of his bone fixation screw and we took out the external fixation but left in place the bone screw, which was obviously still well fixed and the adjacent bone was without signs of infection. There was good secondary wound healing with local and systemic antibiotics. With almost completely healed external wound the patient got an intracranial abscess, that needed neurosurgical drainage. After long-time antibiotic treatment the patient is well again.

[Open surgical treatment of laryngo-tracheal stenoses in children].

BACKGROUND: Treatment strategy in laryngo-tracheal stenoses in children has for a long time been conservative treatment with tracheostomy or bougination in hope of a more or less spontaneous resolution of the stenosis during growth of the child. The results of this option as well as the endoscopic treatment with different laser systems has proved to be rather disappointing. A child with a tracheostomy means a heavy load for the parents to look after this child as well as a constant threat from complications by displacement or plugging of the cannula. METHOD: A retrospective chart review of 22 children, aged between two months and 15 years at the time of surgery with laryngo-tracheal stenoses treated by different open surgical procedures. RESULTS: The aetiology of the stenoses was prolonged endotracheal intubation in 12 children, congenital stenoses in 3 children, unsuccessful laser treatment for acquired stenoses in 3 children, subglottic hemangioma in 3 children and a transglottic cyst in 1 child. 17 cases were treated by laryngo-tracheal reconstruction with rib cartilage graft, 3 crico-tracheal resections, and 2 laryngofissures. Five children could be treated without tracheostomy. From the remaining 17 cases 13 could be decannulated, 1 child died one week after surgery from his congenital heart disease. 3 children are still with a tracheostomy, two of them had had endoscopic laser therapy alio loco before. CONCLUSIONS: Open laryngo-tracheal surgery for paediatric airway stenoses is a successful treatment option besides endoscopic management for selected cases. Resection surgery seems to be indicated for severe stenoses with proliferative scar tissue formation. Depending on personal experience and post-operative facilities procedures without tracheostomy but prolonged post-operative intubation are possible single-stage-solutions.

[Therapy of cystic lymphangioma in childhood. Report of 4 cases with manifestations in the area of the head-neck].

BACKGROUND: Lymphangiomas are localized in the head and neck area in about 75% of cases. About 75% of these cases are children less than one year old. Treating lymphangiomas with installation therapy to obliterate the cysts has been discussed, but surgery remains the treatment of choice. PATIENTS: Two lymphangiomas in newborns required resection due to the size of the lesions. The surgery involved monitoring of the facial and hypoglossal nerves. A third child had a large lesion with infiltration into the supraglottic space and the tongue requiring a tracheotomy. In a four-and-one-half-year-old child, a parapharyngeal lymphangioma caused stridor and had to be incised before it could be completely excised through an intraoral and extraoral approach. RESULTS: Lymphangiomas can be excised safely even in newborns. CONCLUSIONS: The use of neurologic monitoring is recommended for surgery of lymphangiomas in children since these lesions conceal neurovascular structures making them difficult to identify.

Is there an occupational etiology of inverted papilloma of the nose and sinuses?

The etiology of inverted papilloma is believed to be of viral origin, as viruses or viral material is found in these tumors of the nose and paranasal sinuses. As the nose is the first defense line of the respiratory tract, we suspected an etiology of airborne pollution as well, especially occupational pollution. We examined a group of 47 patients treated in our department for nasal inverted papilloma, asking about lifelong professional history and occupational exposure. A matched control group of patients with non-malignant diseases was included in the study. We found a significantly higher degree of occupational exposure to different smokes, dusts, and aerosols in the case group. No similar results have been published to our knowledge. To obtain better proof of the role of possible noxious agents, a study technically investigating exposure is mandatory.

[Laryngeal carcinoma caused by exposure to wood dust?].

Since there is evidence that wood dust may cause adenocarcinoma of the nose and sinuses, the question is whether carcinomas of the remaining upper respiratory tract especially of the larynx might be induced or promoted by occupational exposure to wood dust. We reviewed available evidence and found ten case control studies suggesting a causal relationship, whereas in five case control studies regarding this question such a relationship could not be demonstrated. Six cohort studies did not reveal such a relationship either. It should be mentioned that two cohort studies were designed as registry-based studies including cases without fatal outcome. Even these studies failed to reveal a causal relationship. We conclude that the question as to whether laryngeal cancer might be caused by wood dust exposure is still open. Under these circumstances we cannot recommend classifying this disease-exposure-constellation as an approved occupational disease.

[Etiologically uncertain nasal obstructions in newborn infants].

This is a report on two neonates suffering from a severe nasal obstruction with respiratory distress. The cause of dyspnoea was identified as an abnormal bony narrowing at the level of the apertura piriformis. The etiology of this anomaly remains obscure. Surgical treatment was mandatory and performed as a transnasal approach using the operating microscope and otosurgical instruments. A special stent was used (U-shaped custom-made Portex tube) for several weeks to prevent recurrent narrowing. The advantage of a transnasal approach compared to the sublabial route is described and discussed.

[Embolization of epistaxis after diagnostic biopsy. Case report].

Interventional radiology provides a minimally invasive and less stressful alternative to surgery in the treatment of intractable epistaxis. This is illustrated by the case of an 83-year-old male patient with epistaxis after biopsy of an intranasal metastasis. In this patient embolization obliviated surgery, which was considered a high risk because of the patient's condition.
