Beyond cold cardioplegia.

One hundred fifteen consecutive patients were operated on for myocardial revascularization or valvular disease or both with continuous antegrade and retrograde aerobic warm (37 degrees C) blood cardioplegia. Mean cross-clamp time was 56.3 +/- 21 minutes (+/- standard deviation). Mean reperfusion time was 18.4 +/- 11.8 minutes (range, 5 to 81 minutes). Five patients (4.3%) died, and 15 (13%) needed inotropic support. Two (1.7%) required intraaortic balloon support. Two patients (1.7%) had evidence of perioperative myocardial infarction, and 98 (85%) returned spontaneously to normal sinus rhythm. Sixteen patients had a cross-clamp time greater than 80 minutes. All 16 of them had an uneventful postoperative course except for 1 patient who required inotropic drugs. This method of myocardial protection is now used for all open heart procedures in our institution.

[Heart surgery in normothermia and aerobiosis: apropos of 530 patients].

Between February and October 1991, 530 consecutive patients underwent myocardial revascularization or valvular surgery with warm continuous antegrade and retrograde cardioplegia (37 degrees C). Three hundred and thirty three patients had isolated myocardial revascularization, 159 valvular surgery alone and 25 had combined valvular and coronary bypass. The global mortality was 5.1%, 3.7% for coronary bypass, 7.5% for valvular surgery and 8% for combined valvular and coronary surgery. A multivariate analysis identified the "reperfusion time" as the only predictive factor of hospital mortality (p < 0.001). Intraortic balloon counterpulsation was required postoperatively in 3.2% of cases, 5.2% of coronary bypass and 0.8% of the valvular patients. Inotropic drugs were used to come off cardiopulmonary bypass in 16.5% of coronary and 37.5% of valvular patients. There were 0.9% perioperative infarctions: 1.2% in the coronary bypass cases and 0.6% in the valvular cases. Spontaneous return to sinus rythm was observed in 87.9% of cases. The average "reperfusion time" was 20.48 +/- 0.7 mn. Analysis of the influence of aortic cross clamp time on cardiac morbidity in two groups of coronary patients (Group I: short cross clamp time less than 60 mn; Group II: long cross clamp time, 60 to 33 mn) showed that the hospital mortality, the prevalence of the use of inotropic drugs and balloon counterpulsation the postoperative cardiac index, the rate of spontaneous de fibrillation and the reperfusion time did not depend on the aortic cross clamp time. Cardiac morbidity.

Condylar hyperplasia: cephalometric study, treatment planning, and surgical correction (our experience).

We have studied and treated 12 selected cases of condylar hyperplasia. All of our cases showed no clinical or instrumental sign of still active hyperplastic growth of the mandibular condyle. The cephalometric studies demonstrated in all cases a pathologic vertical growth of the maxilla interesting the posterior segments on the same side of the hyperplastic condyle. We decided not to perform a condylectomy because we did not expect the condyle to grow any further. The treatment consisted of Le Fort I osteotomies and sagittal split osteotomies sometimes in combination with genioplasty and mandibular remodeling. The mandibular physiologic movements were preserved in all cases.

[Reliability of exfoliative cytology in neoplasms of the oral cavity].

Exfoliative cytology is highly important in the early diagnosis of epidermoidal carcinomas of the oral cavity. The simplicity of the test and its nil invasivity make it particularly indicated in the screening of large samples of patients. A double blind study was carried out to evaluate the diagnostic reliability of this technique with regard to the traditional bioptic examination. The data collected are compared with those reported in the literature.

[Surgical approach to benign primary tumors of the para-pharyngeal space].

Surgical access to tumors of the parapharyngeal space can be performed by transoral or trancervical approaches. Risk of intraoperative bleeding and difficulties in radical enucleation represent the disadvantages of transoral approach. This approach must be performed for small and inferomedial lesions, or for preoperative biopsy when necessary. Transcervical approaches can be distinguished in transparotid or transmandibular, or submandibular. Before the late '70s all parapharyngeal masses were approached by transparotid access, with facial nerve manipulation in all cases. CT and MR techniques now allow the right presumptive preoperative diagnosis in 90% of patients. To avoid the risk of injury of the facial nerve when possible, transparotid approach is now limited to the lesions with parotid origin. Transmandibular and submandibular approaches allow an adequate exposure and a direct access to the parapharyngeal space. Personal experience with 6 patients presenting primitive tumors of the parapharyngeal space is reported and surgical approaches proposed in the literature are reviewed.

[Lymph node metastasis of adenoid cystic carcinoma].

BACKGROUND: The adenocystic carcinoma (ACC) of the head and of the neck is rather uncommon. It is characterized by a very slow biological behaviour, which leads to locoregional recurrences and distant metastasis. Most reports concentrate on the unpredictable long-term behaviour of this tumor, whereas lymph nodes metastasis are not usually discussed in detail. The aim of this study was to evaluate the difficulties connected with the lymph node metastasis in ACC. METHODS: A group of 33 patients from 1980 to 1998, was observed. These patients have been subjected to surgical treatment in the Maxillo-Facial Surgery Department of the Policlinico-Umberto I of Rome. RESULTS: Among 33 patients with ACC, 10 patients (30%) revealed, initially or during observation, cervical lymph node metastasis, which is a most common event in male subjects (70%). The lymph node involvement is much more common in carcinomas localized in the parotid and in the sublingual glands with a solid rather than a tubular histologic pattern. Direct correlation between age and metastasis lymph node involvement have not been documented. CONCLUSIONS: Surgery for node disease has a very little impact on the locoregional and on the distant metastasis evolution of the tumor. Thus, our protocol of treatment of lymph nodes metastatic lesions follows the trend of most of the international authors, considering that the neck dissection should be performed only with a lymph adenopathy clinically evident or strongly suspected.

An unusual case of sub-condylar bilateral fracture and bilateral post-traumatic temporomandibular ankylosis.

A case of bilateral sub-condylar fracture with wide stump dislocation associated with a central facial trauma, fracture-intrusion of the rhino-orbital-maxillary complex and a parasymphyseal mandibular fracture, is reported. After surgery and inter-maxillary fixation an unusual temporo-mandibular ankylosis developed. Maximum mouth opening, lateral and protrusive movements were severely limited. Surgical treatment of ankylosis was requested and performed. The originality of this case lies in the atypical lateral dislocation of condylar neck fractured stumps to the zygomatic arches and in the later appearance of ankylosis between the glenoid fossa, zygomatic arch, condylar neck stump, and the condylar process displaced anteromedially. The ankylosed blocks were resected, displaced condyles were also removed due to the strong adhesion with the ankylotic tissue and the lack of any anatomical continuity or connection with the glenoid fossa. Functional therapy allowed the resolution of the functional limitation.
