[Effects of parotidectomy on the blood sugar level and hepatic glycogen (author's transl].

This work was carried out in order to investigate the influence of parotid glands on the metabolism of carbohydrates in the rat. The animals were selected by age (10, 20, 30 and 40 days-old) and distributed in 3 experimental groups as follows: Group I -- Parotidectomized animals; Group II -- Sham-parotidectomized animals; and Group III -- Control animals. The animals from all the groups were sacrificed 20 days after the beginning of the experiment. From the discussion of the results it was observed that the parotidectomized animals at 20, 30 and 40 days have presented significantly larger glycaemic means than control animals. These control animals, by the other hand, have also presented significantly larger glycaemic means than sham-parotidectomized animals. Concerning the 10 days-old animals, the statistical analysis have not showed any significance among the three groups. The results obtained from hepatic glycogen dosages, in the same animals, have showed a coherence, because the animals that have presented larger glycaemic levels, have also presented less hepatic glycogen content; contrarily, the animals that have presented a less glycaemic levels, have also presented a larger amount of hepatic glycogen.

Facial Paralysis

Surgical management of adenoid cystic carcinoma in the parotid gland.

Although adenoid cystic carcinoma may be found in multiple sites in the head and neck as well as other glandular sites throughout the body, nowhere is management of the disease more controversial than in the parotid gland. Here the facial nerve is at risk from both the disease and the treatment. Seventy-five cases of adenoid cystic carcinoma of the parotid were analyzed. Patients were placed in four groups, depending on the type of parotid surgery received as definitive therapy: (1) lateral lobectomy, (2) total parotidectomy, (3) radical parotidectomy without preoperative facial weakness, and (4) radical parotidectomy with preoperative facial weakness. Patients were assessed with regard to staging of the initial lesion, the status of surgical margins, and the use of postoperative radiotherapy. The incidence of local recurrence and distant metastases were also recorded. Survival statistics are presented for each group. Though associated with facial nerve sacrifice, radical parotidectomy appears to offer clear advantages in terms of long-term disease-free survival in patients with T2 and T3 lesions. The residual facial paralysis may be rehabilitated primarily or secondarily to reduce patient morbidity. Four of 16 patients (25%) with preoperative weakness achieved 10-year survival when radical parotidectomy was used. Obtaining clear margins at the initial setting appears to offer improved survival.

[Surgery of pleomorphic adenoma of the parotid gland].

In literature opinion is divided, whether for treatment of pleomorphic adenoma in the parotid gland partial parotidectomy is adequate or complete parotidectomy is necessary. In a retrospective analysis of 123 complete parotidectomies in pleomorphic adenomas the macroscopic tumor extension was compared with the microscopic findings. Additionally 35 pleomorphic adenomas were examined in histological serial sections. The retrospective analysis showed in 6%, the serial sections in 11% microscopic tumor in the macroscopic tumorfree inner lobe. A clinical follow-up examination of 85 patients operated by complete parotidectomy because pleomorphic adenoma resulted in a relapse-quota of 3.5%. The function of the facial nerve was in most cases normal, in 8.2% a weakness of the mandibular branch was found. These results indicate that the risk to leave tumor can be reduced evidently by a complete parotidectomy.

The surgical management of recurrent parotitis.

Twenty-eight parotidectomies were carried out upon 26 patients with chronic parotitis. The lesion considered is chronic inflammation of the parotid gland associated with such intraglandular defects as sialadenitis secondary to ductal obstruction by calculi, cellular debris, stenosis or infiltrating lesions, that is, Mikulicz's or Sjögren's syndromes and sialoangiectasis, either primary or secondary to obstruction of the duct. Seventeen near total parotidectomies were done without significant complications or a recurrence of symptoms. Eleven superficial parotidectomies were performed in which symptoms recurred on the 12th postoperative day in one patient. No permanent weakness of the facial nerve occurred in any of the 28 parotidectomies. Based upon this experience, near total parotidectomy with removal of the parotid duct can be performed safely and should be the procedure of choice in patients with chronic, relapsing parotid sialadenitis.

Chronic Disease

Benign parotid tumors: a 24-year experience.

The medical records of 125 patients benign parotid neoplasms surgically treated over a 24-year period were retrospectively reviewed; 128 tumors were excised. These included 90 pleomorphic adenomas, 33 Warthin's tumors, 3 benign lymphoepitheliomas, and 2 oncocytomas. The surgical procedures consisted of 2 local excisions, 6 enucleations, 88 superficial parotidectomies, 13 subtotal parotidectomies, and 3 radical parotidectomies. The morbidity rate was 49%. There was one total permanent facial nerve paralysis (0.7%), four (3%) partial permanent facial nerve paralysis, five (5%) transient total facial nerve paralysis, and 32 (25%) partial transient facial nerve paralysis. After a median follow-up of 84 months, there was one recurrence (0.7%). A superficial parotidectomy is the minimum procedure that should be performed for the treatment of a benign parotid neoplasm.

Patterns of regional lymph node metastases from cutaneous melanomas of the head and neck.

A consecutive series of 111 patients treated between 1964 and 1989 with primary cutaneous malignant melanoma of the head and neck and histologically proven regional metastases was reviewed to determine the patterns of nodal metastases. The primary sites were grouped in the following categories: face (34), anterior scalp (25), anterior neck (16), posterior scalp (15), ear (11), and posterior neck (10). All patients underwent radical neck dissection: 80 of the procedures were therapeutic and 31 elective. A total of 106 specimens were positive for metastases. Thirty-three of the 57 patients undergoing parotidectomy had positive results for metastases (14 of 20 in therapeutic parotidectomies and 19 of 37 in elective parotidectomies). Based on the incidence of involvement of the parotid gland and the patterns of lymph node metastases from levels I through V, three observations are made. Patients undergoing regional lymphadenectomy for primary melanomas on the ear, face, and anterior scalp should be considered for parotidectomy. The use of selective limited neck dissection for elective regional lymphadenectomy appears justified based on the location of the primary site. In patients undergoing therapeutic neck dissection, a complete neck dissection should be performed due to the unpredictable distribution of lymph node metastases to the cervical lymph nodes.

Acinic cell carcinoma of the salivary glands. A long term follow-up study of 15 cases.

Fifteen cases of acinic cell carcinoma of the salivary glands were evaluated retrospectively with respect to histological and clinical data. DNA content assessment was carried out in six cases by cytophotometry. The majority of tumors were located in the parotid gland and were Stage I at presentation. There was a female predominance and the mean age at primary diagnosis was 51.2 years for females and 41.0 for males. The solid-acinar cell pattern was the most frequently observed and the tumors were 'diploid' in all the six cases studied. Surgery was the therapeutic modality in all cases (enucleation in seven, superficial parotidectomy in three and total parotidectomy in five) and, in four of them, was complemented with radiotherapy. The clinical course was characterized by recurrence in 10 cases, metastases occurred in three patients and one patient died of the tumor. Of the seven recurrent cases, six were treated by enucleation and one by superficial parotidectomy. The histological pattern showed no correlation with the clinical course or DNA content. Acinic cell carcinoma has a significant morbidity with a high recurrence rate which seems to be largely influenced by the type of surgery employed. Wide surgical excision of the neoplasia, which includes total parotidectomy in the parotid cases, is recommended in order to reduce the frequency of recurrence of the tumor.
