Fractures of the orbital floor.

The charts of 324 patients treated for 363 orbital floor fractures between 1965 and 1973 were reviewed retrospectively. Of these, 38 (11 percent) were isolated floor fractures, 27 (8 percent) were rim and floor fractures, 168 (46 percent) were trimalar fractures and 130 (35 percent) were associated with complex facial fractures. On initial examination, 31 percent of the patients were found to have diplopia and 4 percent enophthalmos. Orbital prolapse was suspected in 31 percent of the patients. Thirty-seven percent of the patients had demonstrable ocular injury at the time of initial examination. Treatment was surgical in 336 of the fractures and non-surgical in 29. Of the surgical patients 140 had no support placed, 120 had antral support only, 51 had both antral support and orbital implant, and 20 had an orbital implant only. Postoperatively the incidence of diplopia was 8 percent in all patients, and 7 percent had enophthalmos. A smaller group followed for more than five months, were found to have diplopia in 17 percent and enophthalmos in 11 percent. Of the 29 patients treated non-surgically, none had persistent diplopia.

The risks of major head and neck surgery in the aged population.

A review of 162 major head and neck operative cases for cancer in patients over age 70 from 1963-1973 are reviewed. The major and minor surgical complication rates and the rate of medical complications are compared to 552 similar procedures in patients under age 70, during the same time period. The operative mortality figures for each group, as well as the causes of death, are examined. A plea is made for aggressive therapy in the elderly, both in the surgical planning and in their pre- and postoperative care.

Reconstruction of the oral cavity with a free flap.

Free groin flaps were used successfully within the oral cavity in 4 patients after ablative operations for cancer. Preoperative or postoperative radiation (cobalt therapy) had no apparent detrimental effect on the survival of these free flaps.

A comparative study of results of the von Langenbeck and the V-Y pushback palatoplasties.

The incidence of velopharyngeal competence noted in 267 cleft palate patients following palatoplsty has been reviewed. Comparisons have been drawn with regard to the cleft type and the surgical technique performed. Since there were relatively small numbers of subjects in some categories, differences in age at last examination between the von Langenbeck and V-Y palatoplasty groups, some patients were very young at time of evaluation, and a number of different surgeons at different levels of training and experience performed the surgery, the differences in velopharyngeal competence found should be viewed as trends and this report as preliminary. In general, there was a trend toward smaller percentages of patients attaining acceptable velopharyngeal competence as the severity of the cleft increased. Of those with clefts of the soft palate only 86 per cent achieved competence. Among those patients with clefts of the palate only, 67 per cent achieved competence, whereas only 57 per cent of those with clefts of the lip and palate were able to do so. When comparing all cleft types, the V-Y palatoplasty resulted in a significantly higher percentage of velopharyngeal competence (74 per cent) than did the von Langenbeck method (56 per cent), although the data for the V-Y group are probably less reliable than those for the von Langenbeck group. In the soft palate only category, the results were slightly better with the von Langenbeck technique, though not significantly so. In all other cleft types, the results with the V-Y method were better than those with the von Langenbeck.

Facial and dental relationships of individuals with unoperated clefts of the lip and/or palate.

Twelve individuals with unoperated unilateral clefts of the lip and palate and eight with unoperated unilateral clefts of thelip and alveolus were examined clinically and cephalometrically. The two groups were compared to each other and to a matched sample of normal individuals. All subjects were examined in their native India. Based on the findings of this investigation, it is suggested that, in general, the cranial base and skeletal face are not extensively malrelated in individuals with either unoperated unilateral clefts of the lip and palate or of the lip and alveolus when compared to matched normals. Yet, there are distinct differences in dentoalveolar and skeletal relations between both cleft groups and normals and between the two cleft groups.

Radical neck dissection: Elective, therapeutic, and secondary.

The effectiveness of elective en bloc, therapeutic en bloc, and secondary radical neck dissections is evaluated in patients whose primary tumor remained controlled following initial treatment (surgery, irradiation, or combined therapy). Pathologically documented cervical involvement following elective en bloc, therapeutic en bloc, and secondary radical neck dissections occurred in 80 (27%) of 295, 158 (67%) of 237, and 77 (75%) of 102 of the patients, respectively. Patient survival is greater if cervical metastases are surgically removed while occult, rather than if they are resected after they are clinically suspected. Patients who have a 15% to 20% or greater likelihood of having occult cervical metastases will have an increased probability for survival if the surgical management includes an elective en bloc radical neck disection.

Augmentation rhinoplasty.

Augmentation of the depressed nasal dorsum may be accomplished in a variety of ways by utilizing a number of different implant materials. Several techniques are discussed and illustrated. Small areas of depression may be corrected with viable or nonviable cartilage or synthetic implants through an intercartilaginous incision. More extensive saddling is best augmented using either iliac bone placed subperiosteally or irradiated cartilage. When the implant is sizable or a two piece "L shaped" strut is required, placement is done through a gingivolabial sulcus incision.
