The treatment of lymphangioma in the buccal mucosa by radiofrequency ablation: a case report.

Lymphangioma is a benign, hamartomatous tumor of the lymphatic system. It is usually found in the head and neck region and is widely regarded as a developmental lesion rather than a true neoplasia. Most lymphangiomas are present at birth (60%), and by the age of 2 years 80% to 90% are present. In the head and neck area, the most common location is the submandibular region, followed by the parotid gland. When lymphangioma occurs in the mouth, the anterior two thirds of the tongue is the most commonly affected region. Various methods have been tried for treatment of lymphangioma including surgery, radiation, laser therapy, and sclerotherapy. Recently, a new and more conservative surgical approach to this lesion using radiofrequency ablation has been described. In this report, a case of lymphangioma in the right buccal mucosa of the mental foramen area that has been treated by radiofrequency ablation is presented.

Accessory nerve function in lateral selective neck dissection with undissected level IIb.

BACKGROUND: To investigate the accessory nerve function in lateral selective neck dissections (LSND) performed in laryngeal squamous cell carcinoma patients without dissection of level IIB. METHODS: Fifteen LSND were performed in 11 N0 laryngeal carcinoma patients with preservation of level IIB. Distal latencies, compound muscle action potentials (CMAP), and electromyography findings were investigated before surgery, during the 3rd postoperative week, and 3 months thereafter to compare the effects of the procedure on the accessory nerve. RESULTS: Distal latencies and CMAP values were significantly lower in the early and late postoperative periods when compared with preoperative values. In 8 patients, there was no motor unit potential (MUP) in the early postoperative period. However, in the late postoperative period, there was no MUP loss. CONCLUSIONS: Only temporary functional deterioration of the accessory nerve was seen in patients in whom LSND was performed with undissected level IIB.

[Isolated inverted papilloma of the sphenoid sinus: a case report].

Inverted papilloma is a rare benign sinonasal tumor characterized by a potentially invasive nature. The lateral nasal wall represents the most common site of origin, whereas paranasal sinuses are frequently involved by extension. In contrast, primary sinus inverted papillomas have rarely been reported. The present study describes a 52-year-old man that presented with a one-year history of unilateral nasal obstruction, nasal discharge, epistaxis, occipital headache and decreased sense of smell. After nasal endoscopic examination, computed tomography was taken and endoscopic biopsy was performed which demonstrated isolated inverted papilloma of the left sphenoid sinus. Tumor was taken via transnasal endoscopic sphenoidotomy. No evidence for recurrent disease was seen after 12 months of follow-up and his symptoms were completely relieved. Endoscopic transnasal sphenoidotomy remains an effective treatment for these lesions.

[Endoscopic surgery of sphenochoanal polyp].

Sphenochoanal polyp is a rare entity originating from the sphenoid sinus. It may be confused with an antrochoanal polyp on anterior rhinoscopy. Computerized tomography and nasal endoscopy have contributed to an increase of accuracy in the diagnosis of these masses. Simple polypectomy that leaves some part of the polyp inside the sphenoid sinus carries a high risk of recurrence. We present a case of sphenochoanal polyp in a child that was operated by endonasal endoscopic approach. She was free of symptoms after surgery. No complications and recurrences were observed at 16 months of follow-up periods respectively.

[Auricular arteriovenous fistula: a case report and therapeutic approach].

A case of arteriovenous fistula (AVF) arising in the auricle was presented together with its treatment. A 20-year-old man with an AVF on the right auricle was successfully treated with superselective embolization followed by ligation of the arteries supplying the fistula. The lesion underwent considerable regression within a follow-up period of five months and no complications were encountered. Small AVFs existing among several vessels can be satisfactorily treated by embolization and ligation of the vessels instead of extensive resection of the lesion.

Thyroid gland invasion in advanced laryngeal and hypopharyngeal carcinoma.

OBJECTIVES: To assess the rate of thyroid gland invasion and the need for thyroidectomy in advanced laryngeal and hypopharyngeal carcinomas that require total laryngectomy. PATIENTS AND METHODS: Between 1994 and 2001, 129 total laryngectomy with ipsilateral hemithyroidectomy and 14 total laryngopharyngectomy with total thyroidectomy operations were performed for primary squamous cell carcinoma of the larynx and hypopharynx. In the surgical specimens of the patients, the presence of tumor invasion to the thyroid cartilage and thyroid gland was evaluated retrospectively by light microscopic examination. RESULTS: None of the laryngeal carcinoma patients had thyroid gland invasion whereas eight (57%) hypopharyngeal carcinoma patients had thyroid gland invasion. Twenty patients (16%) had evidence for thyroid cartilage invasion in the laryngeal carcinoma group. There were only three cases (21%) with thyroid cartilage invasion in the hypopharyngeal carcinoma patients. CONCLUSION: There may be no need for performing thyroidectomy in all total laryngectomy cases. We recommend thyroidectomy during total laryngectomy in laryngeal carcinoma cases with subglottic extension and advanced hypopharyngeal tumors. Except for these two conditions, the assessment of extralaryngeal extension and thyroid gland invasion will guide whether thyroidectomy should be performed or not.

[Epiglottic anteversion in the etiology of globus pharyngeus and its surgical management].

OBJECTIVES: To define the role of epiglottic anteversion in the etiology of globus pharyngeus (GP) and to evaluate the effectiveness of laser partial epiglottectomy in its treatment. PATIENTS AND METHODS: Four patients who admitted to our clinic between 2001 and 2003 with the complaint of GP underwent laryngoscopic examination, which revealed a structurally anteverted epiglottis that was in contact with the tongue base and vallecula. After ruling out other etiologic factors of GP, the patients were operated on under general anesthesia and laser partial epiglottectomy was carried out. In this procedure, the part of the epiglottis 1 cm from the free margin, forming the contact points with the tongue base and vallecula was excised with laser. RESULTS: Three patients were symptom-free totally, while one patient reported a partial cure. CONCLUSION: Epiglottic anteversion should be kept in mind in the etiology of GP. Laser partial epiglottectomy may be helpful in the treatment of selected cases.

Comparison of pharyngoesophageal segment pressure in total laryngectomy patients with and without pharyngeal neurectomy.

BACKGROUND: To compare pharyngoesophageal segment (PES) pressure values in total laryngectomy patients with and without pharyngeal neurectomy (PN) in the early postoperative period. METHODS: Forty-five previously untreated laryngeal carcinoma patients were enrolled into this prospective randomized study. Twenty of them underwent total laryngectomy with PN, and 25 underwent total laryngectomy without PN. PES pressures were measured on the tenth postoperative day with a four-channel catheter. RESULTS: Average PES pressures in patients with and without pharyngeal neurectomy were 12.82 +/- 6.11 mmHg and 17.40 +/-.72 mmHg respectively (p <.05). When compared with the critical point of 20 mmHg that is closely related to voice attainment in the group without pharyngeal neurectomy, 10 (40%) patients had pressure levels greater than 20 mmHg and in the other group only 1 (5%) patient had a pressure level greater than 20 mmHg. The difference between the groups with pressure levels greater than 20 mmHg was found to be statistically significant (p <.05). CONCLUSIONS: Pharyngeal neurectomy results in a statistically significant decrease of PES pressures in total laryngectomy patients.

Lymphatic metastasis to the supraretrospinal recess in laryngeal squamous cell carcinoma.

In order to evaluate lymphatic metastasis to the supraretrospinal recess (SRSR) in laryngeal squamous cell carcinoma (SCC), we separately dissected SRSR lymph nodes and submitted them to pathological examination. Fifty-three lateral neck dissections (LNDs), 2 radical neck dissections (RNDs), and 19 modified RNDs were performed in 49 previously untreated patients with laryngeal SCC. The nodal status of the patients was N0 in 29 patients, N1 in 17, and N2 in 3. The neck was pathologically positive in both RNDs (100%), in 7 of 19 modified RNDs (37%), and in 7 of 53 LNDs (13%). No SRSR lymph nodes were positive in any of the dissection materials. No metastasis was found in the SRSR lymph nodes in the N0 necks treated with LND, and none was found even in N1 and N2 necks treated with RND or modified RND. We conclude that the SRSR may be left undissected during treatment of an N0 neck with LND so that accessory nerve dysfunction can be minimized and operative time can be saved.
