Leiomyosarcoma of the larynx. Review of the literature and report of two cases.

Leiomyosarcoma of the larynx is an extremely rare malignancy. Until now, only 35 cases have been reported, and only 19 were reported in English. We present 2 new cases observed in the last 3 years at our department. Correct histologic diagnosis can only be made on immunohistochemical and electron microscopic grounds. A 65-year-old man previously treated for a premalignant vocal cord lesion and a 31-year-old woman who previously underwent operation on a benign vocal cord lesion are presented. Only surgical treatment (total laryngectomy and endolaryngeal laser resection) was performed. Thirty-six and 22 months after the initial surgical intervention, both patients are alive and well, with no evidence of local recurrence or distant metastasis.

Detection of Osteoprotegerin and TNF‐alpha mRNA in Ankylotic Stapes Footplates in Connection With Measles Virus Positivity

Hypothesis: Otosclerosis is a bone remodeling disorder of the otic capsule causing conductive and sensorineural hearing loss. Persistent measles virus infection of the temporal bone with increased tumor necrosis factor (TNF)‐alpha and decreased osteoprotegerin mRNA expression is supposed to be the main etiologic factor in otosclerosis.

ALA (5-aminolevulinic acid)-induced protoporphyrin IX fluorescence in the endoscopic diagnostic and control of pharyngo-laryngeal cancer.

Photodynamic diagnosis is a modern method for the fluorescence imaging of superficial pharyngeal and laryngeal tumours. 5-aminolevulinic acid (ALA)-induced protoporphyrin IX fluorescence benefits the tumour selective accumulation of protoporphyrin; therefore, tumours can be differentiated from healthy tissue. ALA-induced fluorescence of laryngo-pharyngeal tumours and precancerous and benign lesions were evaluated by endoscopy. At the Department of Otorhinolaryngology, Head and Neck Surgery, Szeged, Hungary, 31 patients underwent ALA-induced protoporphyrin fluorescence imaging. After topical application of ALA, mesopharyngeal tumours were visualised by direct fluorescence endoscopy. Laryngeal and hypopharyngeal tumours were examined with a laryngomicroscope with the patients under general anaesthesia after inhalation of an ALA solution. Intensity of PPIX fluorescence was classified and compared with pathological findings. The examination of all 13 laryngeal and 12 pharyngeal tumours resulted in a middle or strong intensity of red fluorescence, but for one cancer, four praecancerous and two benign lesions. Healthy tissues showed green autofluorescence. Margins of mesopharyngeal and vocal cord tumours were clearly outlined under fluorescent vision, giving a helpful contribution to diagnosis and therapy even in clinically non-visible tumours. Laryngomicroscopy combined with laser surgery also indicated PPIX fluorescence examination visualising margins of the tumour intermediately with the endoscope. The ALA-induced PPIX fluorescence imaging method revealed a sensitivity of 96%. This method is applicable for detecting early superficial tumours, margins of tumours and follow-up after surgery/radiation therapy in the laryngo-pharynx.

Airway complication after thyroid surgery: minimally invasive management of bilateral recurrent nerve injury.

Objectives: After bilateral vocal cord paralysis, the consequent paramedian position usually necessitates tracheostomy for at least 6 months, when the paralysis is potentially reversible. In the present study a reversible endoscopic vocal cord laterofixation procedure was used instead of tracheotomy.

Codetection of Measles Virus and Tumor Necrosis Factor-Alpha mRNA in Otosclerotic Stapes Footplates†

Hypothesis: Otosclerosis is a disease of unknown etiology causing conductive or sensorineural hearing loss. Persistent measles virus infection of the otic capsule is considered to be one of the etiologic factors in otosclerosis.

Vocal cord laterofixation as early treatment for acute bilateral abductor paralysis after thyroid surgery

Abstract Bilateral vocal cord palsy due to a lesion of the recurrent laryngeal nerves is a serious complication of thyroid operations, with the airway obstruction usually necessitating tracheostomy. In the cases presented, a stable airway was ensured with endolaryngeal cord laterofixation instead of tracheostomy. The operation was performed with the endo-extralaryngeal needle carrier instrument devised by Lichtenberger. During the operation, only minor surgical trauma occurred in the larynx. The fixing thread was then removed following recovery of contralateral vocal cord function, resulting in an improvement in the voice. Four patients are described who suffered bilateral recurrent laryngeal nerve palsy after thyroid gland operations. During the follow-up period of 3–12 months, airway stability was demonstrated by regular spirometric measurements. The simple method recommended spares patients the possible complications of tracheostomy.

Antimeasles immunoglobulin g for serologic diagnosis of otosclerotic hearing loss.

Hypothesis: Persistent measles virus infection of the otic capsule is suggested to be an etiologic factor in otosclerosis. Otosclerosis is a disease of complex unknown etiology causing progressive conductive and/or sensorineural hearing loss (HL).

Endoscopic Arytenoid Lateropexy for Isolated Posterior Glottic Stenosis

Objectives/Hypothesis: A posterior glottic stenosis (PGS) may limit the abduction of the arytenoid cartilages. One option for the treatment of dyspnea in lower grade stenoses is endoscopic laterofixation of the vocal cords after scar excision. In our prospective study, we assess a refined method for effective endoscopic mobilization and lateropexy of the arytenoid cartilages.

Cholesterol granuloma of the maxillary sinus resembling an invasive, destructive tumor

The case of a maxillary sinus cholesterol granuloma posing as a malignant tumor is presented. The patient was referred to the authors’ clinic with symptoms typical of maxillary sinusitis, but physical examination suggested the presence of neoplasm. Radiology also resulted in confusing, tumor-like pictures. Histological examination of a preoperative tissue sample identified the process as a cholesterol granuloma, which was removed by a classic Caldwell-Luc operation. The patient has been symptom free since the operation. The pathogenesis of cholesterol granuloma is described, and the problems of establishing a diagnosis without preoperative histology are discussed.

Early vocal cord laterofixation for the treatment of bilateral vocal cord immobility.

Objectives: Vocal cord immobility (VCI) is commonly caused by a nonlaryngeal malignancy, thyroid surgery, or a presumed viral insult etc. The paralysis is often transient or temporary, thus the care of the patient should be optimized to avoid unnecessary diagnostic and therapeutic endeavours. This article reports on the result of the concept of early vocal cord laterofixation, which provides a minimally invasive solution to dyspnea in the critical early, potentially reversible, period of bilateral VCI. Study design: A prospective study of 25 consecutive patients (ages 33 to 81 years) who were diagnosed with a bilateral VCI. This condition had developed after thyroid surgery in 22 of the patients and after a blunt trauma of the neck in one case. In another case, a cricoarytenoid joint fixation was revealed, and aetiology remained unknown in one further patient. Methods: The surgical procedure was performed endoscopically with a modification of Lichtenberger’s endo-extralaryngeal suture lateralization technique. The abducted vocal cord position was achieved by inserting a non-resorbable thread around the vocal process and tying on to the prelaryngeal muscles. Regular spirometric measurements and radiological aspiration tests were conducted on the patients. Results: Adequate postoperative airway was achieved in all patients except one. Significant spontaneous vocal cord medialization was observed in two cases within a year and in three patients in the second and the third year. Partial or complete vocal cord recovery was observed in 17 cases. Further voice improvement followed in 9 patients when the threads were removed, due to vocal cord medialization or recovery. The mild postoperative aspirations ceased in the first postoperative days in all cases except one. Conclusions: The concept of “early” laterofixation satisfies the important criteria: it can provide an immediate and long-lasting adequate airway, and it can be considered potentially reversible from the point of view of laryngeal functions. Thus the procedure is a reliable primary treatment for bilateral VCI.
