[Clinical analysis of 14 patients with extraorbital inflammatory myofibroblastic tumor of the head and neck].

Objective: To summarize the clinical features of extraorbital inflammatory myofibroblastic tumor (IMT) of the head and neck.

Methods: Fourteen cases of extraorbital IMT treated in recent 20 years were analyzed retrospectively.

Results: Of the 14 patients, 9 cases with limited lesion in maxilla (n = 5), mandible (n = 2) or neck (n = 2) underwent local resection, and no recurrences were found after 1.

[Relevance of Endoglin (CD105) VEGF and p53 with invasion metastasis and prognosis of laryngeal carcinoma].

Objective: To evaluate the clinical significance of microvessel density (MVD) and investigate the relationship of Endoglin (CD105), VEGF and p53 protein and their significance of clinical pathology.

Method: Pathologic paraffin-embedded tissues and clinic data of 40 patients with primary squamous cell carcinoma of larynx were studied. Serial sections were respectively stained with Endoglin (CD105), VEGF and p53 by immunohistochemistry and its expressions were investigated.

[Surgical management of tumor in the conjunctive area among neck, thorax and axilla].

Objective: To study the surgical management of tumors in the conjunctive area among the neck, thorax and axilla and its efficacy.

Methods: From Oct. 1999 to March 2006, eleven cases with benign tumors in the area between the neck, thorax and axilla were collected and analysed.

[Complications of tracheoesophageal puncture for Blom-Singer voice restoration after total laryngectomy].

Objective: To investigate causes and treatment of complications of tracheoesophageal puncture for Blom-Singer voice restoration after total laryngectomy.

Methods: From 1986 to 2004, one hundred and fifty one cases with Blom-Singer technique after total laryngectomy for voice restoration were retrospectively analyzed.

Results: All cases were followed up from 6 months to 15 years.

[Diagnosis and surgical management of metastatic diseases in retropharyngeal space].

Objective: To evaluate the symptoms and surgical management results of metastatic disease in the retropharyngeal space.

Methods: Six patients with malignant tumors were collected, in which enlarged lymph nodes presented both in neck and retropharyngeal space. They consisted of two supraglottic carcinoma (T3N2MO), one thyroid carcinoma (TXN2MO), one nasal melanoma (TXN2MO), one oropharyngeal carcinoma (T2N2M0) and one hypopharyngeal carcinoma (T3N2MO).

[Head and neck manifestations and management of Wegener's granulomatosis].

Objective: To explore the characteristic and management of Wegener's granulomatosis in head and neck.

Method: Forty-two cases with Wegener's granulomatosis were retrospectively analyzed clinical characteristics, head and neck manifestations, biopsy, ANCA test, and management were respectively recorded. Cyclophosphamide and Prednisone are the mainstay of medical therapy.

[Long-term results of tracheoesophageal puncture for voice restoration after total laryngectomy].

Objective: To evaluate the long-term results of tracheoesophageal puncture for Blom-Singer voice restoration after total laryngectomy and summarize our clinical experience of fifteen years.

Method: From 1986 to 2001, one hundred and thirty four cases with Blom-Singer technique after total laryngectomy for voice restoration were analyzed retrospectively. MDVP of Kay Elemetrics was used to analyze the acoustic parameters of eighteen cases with Blom-Singer indwelling voice prosthesis for 2-14 years.

[Forty-three tracheal stricture with Ni-Ti shape memory alloy stent].

Objective: To evaluate the application of Ni-Ti shape memory alloy stent for treating tracheal stricture, including its indications and complications.

Methods: Forty-three patients clinical data were analyzed, among them, 15 suffered from tumor; 7 trauma; 4 granulation; 1 Wegener's granuloma, 2 rhinoscleroma, 1 without clear diagnosis; 7 were relapsing polychondritis; 1 were respiratory amyloidosis; 4 were tracheobronchial tuberculosis, 5 were tracheobronchomalacia. The stricture degree: Level I: 15 patients, Level II:24 patients, Level III:4 patients.

[Surgical management of metastatic disease in the conjunctive area between neck and thorax].

Objective: To study the surgical management of metastatic disease in the conjunctive area between the neck and thorax and its efficacy.

Methods: Fourteen cases with metastatic node disease in the area between neck and thorax were collected and analysed. Eleven tumors were from the thyroid cancer, and the other three were from the hypopharyngeal cancer, esophagual cancer and malignant pheochromocytoma, respectively.

[Pharyagoesophageal sphinoter myotomy for voice rehabilitation after total laryngectomy].

Objective: In those patients received total laryngectomy, Blom-Singer prosthesis speech appears to be the more effective form of rehabilitation. To reduce the effect of pharyngoesophageal sphincter on the Blom-Singer prosthesis voice restoration following total laryngectomy, the pharyagoesphageal sphincter myotomy was designed and carried out.

Methods: After total laryngectomy, the cricopharyngeus muscle stricture or spasm appears to inhibit the air flowing and prevent the speech.
