Shoulder function after accessory nerve-sparing neck dissections.

BACKGROUND: This study was designed to observe the effect of preserving the spinal accessory nerve (SAN) during neck dissection (ND) and adjuvant radiotherapy (ART) after ND on shoulder function. METHODS: Fifty-seven patients with head and neck cancer who had undergone primary tumor resection and various types of NDs were enrolled in this prospective study. Postoperative shoulder joint range of motion was evaluated by goniometry, and muscle strength was measured manually. SAN function was evaluated with electromyography (EMG) with respect to percentage of denervation and presence of neurogenic involvement. Patients were grouped by treatment as follows: radical ND (RND) versus modified radical ND (MRND)/selective ND (SND) and ART versus no ART. RESULTS: Shoulder joint range of motion and shoulder muscle strength were significantly better in the MRND/SND group than in the RND group. However, EMG findings were similar in the RND and MRND/SND groups. When all patients who underwent ND, RND, or MRND/SND were compared with the control group, statistically significant changes in shoulder joint range of motion and shoulder muscle strength were found. Also, denervation and neurogenic involvement of the SAN were significantly higher after all NDs than in the control group. ART did not affect range of motion of the shoulder joint, shoulder muscle strength, or the degree of denervation and neurogenic involvement in any of the ND groups. CONCLUSIONS: ART does not have a negative effect on shoulder function after ND. SAN is always functionally impaired even if we preserve it macroscopically during ND.

Basaloid squamous cell carcinoma of the larynx: a report of four new cases.

OBJECTIVES: This study is designed to report the clinical and pathologic features and outcome of cases of basaloid squamous cell carcinoma (BSCC) of the larynx treated in our clinic. STUDY DESIGN: A retrospective review of the medical records of these patients. METHODS: Four cases of BSCC of the larynx were treated in our department. Histopathologic slides were reevaluated to confirm the diagnosis. Immunohistochemical studies were performed, and file records were reviewed. Follow-up was available for all patients and ranged between 11 and 72 (mean 37) months. RESULTS: All patients were male (mean 57), with supraglottic or transglottic larynx tumors. Two patients presented with stage-II disease and the other 2 with stage-IV disease. Initial diagnosis was invasive squamous cell carcinoma in 3 patients and BSCC in one patient. Two patients who had stage-II disease underwent partial laryngectomy and bilateral neck dissections; total laryngectomy and bilateral neck dissections were performed in stage-IV patients. Three patients received adjuvant postoperative radiotherapy, and 2 of them also received additional chemotherapy. Patients with stage-IV disease were found to have 4 and 27 metastatic lymph nodes on histopathologic examination and died because of distant metastases at 11 and 14 months, respectively. Patients with stage-II disease did not have cervical metastasis on histopathologic examination and were alive and free of disease at 52 and 72 months respectively. CONCLUSION: In contrast with the literature reporting the tendency of more aggressive clinical behavior of the BSCC, we can say that BSCC has a behavior similar to conventional squamous cell carcinoma based on our 4 cases.

Incidental association of thyroid carcinoma and squamous cell carcinoma of head and neck.

PURPOSE: This study was carried out to address the dilemma of managing incidentally associated squamous cell carcinoma of the head and neck and thyroid carcinoma. MATERIALS AND METHODS: The patient group consists of 229 consecutive cases of squamous cell carcinoma of the head and neck and who were treated surgically at the Uludag University School of Medicine Department of Otolaryngology over a four-year period between 1997 and 2000. RESULTS: Among these patients, 3 had additional thyroid papillary carcinoma metastases (1.3%, 3/229) within the surgical specimens of the surgical procedures performed for squamous cell carcinoma of the head and neck. Complementary thyroidectomy was recommended but could not be performed in one of three cases because of the patient's refusal, and the primary focus of thyroid carcinoma could be found in only one of these two cases who had undergone complementary thyroidectomy. All three patients received postoperative radioactive iodine and thyroid hormone suppression, and all are free of disease after 49, 46, and 19 months of follow-up, respectively. CONCLUSIONS: Management of thyroid carcinoma found incidentally during treatment of squamous cell carcinoma of the head and neck is still debatable, and all patients must be evaluated individually with regard to its benefit. Our limited experience suggests that total thyroidectomy may not be regarded as mandatory in managing these patients.
