The relationship between shoulder pain and damage to the cervical plexus following neck dissection.

The aim of our study was to evaluate the relationship between shoulder pain and damage to the cervical plexus after neck dissection. The study was performed prospectively on 34 neck sides of 17 patients with laryngeal cancer who underwent laryngectomy plus bilateral selective neck dissection (II, III, IV, +/- VI) at the Department of Otorhinolaryngology of Uludag University between December 2003 and October 2004. The cervical plexus was protected on one side of the neck and sacrificed on the other, while the accessory nerve was spared on both sides. The degree of sensorial innervation of the cervical plexus and shoulder pain were evaluated in the preoperative period and postoperatively at 2 weeks, 1 month, 3 months, and 6 months. Data obtained from both sides of the neck were compared. Sensory reception scores were statistically higher in the neck sides in which the cervical plexus was spared than in those where the plexus was sacrificed (P < 0.05). However, the degree of shoulder pain was similar on both sides of the neck (P > 0.05). Damage to the cervical plexus during neck dissection causes loss of sensorial innervation of the neck, but sacrificing the cervical plexus during selective neck dissection has no negative effect on shoulder pain.

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.

[The management of pharyngocutaneous fistulas after total laryngectomy and the factors affecting their incidence]. / Total larenjektomi sonrasi farengokutanöz fistül gelisimini etkileyen faktörler ve fistül tedavisine yaklasimimiz.

OBJECTIVES: This study sought to determine the incidence and etiologic factors of pharyngocutaneous fistulas occurring after total laryngectomy. PATIENTS AND METHODS: A total of 138 patients (136 males, 2 females; mean age 59.5 years; range 36 to 83 years) underwent total laryngectomy for squamous cell carcinoma. Risk factors and the management of pharyngocutaneous fistulas were assessed together with durations in relation to fistula occurrence, oral feeding, hospitalization, and healing. RESULTS: Pharyngocutaneous fistulas were seen in 37 patients (26.8%). Significantly high rates of fistula occurrence were detected in patients with alcohol consumption (p=0.032), and in those who underwent partial pharyngectomy (p=0.058) or bilateral neck dissection (p=0.049) along with total laryngectomy. The occurrence of fistulas was significantly associated with prolonged lengths of time for oral feeding and hospital stay (p<0.001). Fistulas were repaired surgically in 24.3% of patients, in whom the time to oral feeding was significantly shorter than that of patients who received local wound care (p=0.03). CONCLUSION: Our data show that early surgical intervention is more beneficial in preventing further morbidity associated with pharyngocutaneous fistulas.

[The incidence of hyperinsulinemia in patients with tinnitus and the effect of a diabetic diet on tinnitus]. / Tinnituslu hastalarda hiperinsülinemi sikligi ve diyabet diyetinin tinnitus üzerine etkisi.

OBJECTIVES: We investigated the incidence of hyperinsulinemia in patients presenting with tinnitus and evaluated the effect of diabetic diet on tinnitus. PATIENTS AND METHODS: Serum insulin levels were measured and oral glucose tolerance test was performed in 52 patients (26 males, 26 females; mean age 50 years; range 20 to 80 years) with idiopathic tinnitus. Those with hyperinsulinemia were given a diabetic diet for four months. A questionnaire was administered to all the patients and the complaint of tinnitus was assessed according to a rating scale before and after treatment. The results were compared with those of 15 age-and sex-matched controls. RESULTS: Hyperinsulinemia was detected in 76% and 27% of the patients and the controls, respectively (p<0.05). Oral glucose tolerance test was normal in 48% of the patients, and in 80% of the controls (p<0.05). Following a diabetic diet, the severity of tinnitus complaints significantly decreased in patients with hyperinsulinemia (p<0.0001). CONCLUSION: Hyperinsulinemia may play an etiologic role in tinnitus and a diabetic diet may result in significant improvement in tinnitus complaints in this population.

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.
