Iliac apophyseal cartilage augmentation of the deficient piriform rim and maxilla in alveolar cleft grafting.

This article presents a new approach to cleft lip and cleft palate repair, where the retained bulk of alveolar cleft grafts is augmented by simultaneous cartilage augmentation of the deficient maxilla. Nine patients who provided 10 cleft sites underwent secondary bone grafting of the clefted alveolus by this technique. This study evaluates the following: (1) the postoperative esthetic results, (2) the quantity of bone in the grafted area, and (3) the provision of bone support for unerupted teeth, for teeth adjacent to the cleft, and for orthodontic tooth movement when the secondary bone grafting of the cleft is integrated with the onlay augmentation of the deficient maxilla. Photographic and radiographic investigations were undertaken. The photographic evaluation showed that all patients exhibited improved facial esthetics in the area of the cleft, particularly in the paranasal area of the maxilla; improved alar base support, symmetry of the columella, and less deviation of the tip of the nose were seen. The radiographic evaluation indicated the following: (1) the average percentage of the alveolar bone height of the grafted area was equal to 76% of the normal side; (2) nine canines erupted or were erupting through the grafted area; there were no adequate records to evaluate the fate of the remaining canine; (3) no teeth involved in the cleft area were ankylosed, because of inadequate records, so evaluators could not determine the status of one tooth; (4) all patients had adequate quantity of bone for orthodontic tooth movement through the grafted area; and (5) the periodontal support of the teeth involved in the cleft was adequate.

Stability of transient, semirigid pin fixation of sagittal split mandibular osteotomies.

Cephalometric records of 16 patients who underwent mandibular lengthening, stabilized with noncompressive pin fixation, were examined retrospectively. Digitization and computer analyses of the cephalometric changes for various time intervals were performed. All linear changes were stable for 13 of the 16 patients over the follow-up period of 2 years. No significant correlation was found between postoperative horizontal relapse and amount of advancement. A high degree of postfixation stability was obtained with very short fixation periods. While further study of this pin fixation technique is indicated, these preliminary results are favorable.

Simultaneous maxillary and nasal reconstruction. An analysis of twenty-five cases.

This study measures the changes in nasal morphology which accompany simultaneous rhinoplastic and orthognathic reconstruction. The sample includes 25 patients treated over a four-year period, using either facial degloving access or more limited nasal skeletonization in combination with oral incisions. Midfacial and maxillary procedures were performed, as were mandibular osteotomies, intercurrent to both nasal reduction and augmentation. Radiographic, photographic, and clinical assessment selected for skeletal stability and nasal airflow, followed by nasal dorsum, nasal tip, alar and columellar bases, and labial modifications. The relationships of skeletal to soft tissue movements thus obtained are discussed by way of establishing norms, comparing the two approaches, and integrating recent innovations of both rhinoplastic and orthognathic surgery to this abbreviated mode of anatomic and functional reconstruction.

Autosomal dominant transmission of ankylosed teeth, abnormalities of the jaws, and clinodactyly. A four-generation study.

Twelve persons in four generations of a rural family of mixed racial ancestry exhibited ankylosed teeth, bilateral clinodactyly of the fifth fingers, and abnormalities of the jaws. This previously undescribed association of dental, digital, and skeletal anomalies appears to be transmitted in an autosomal dominant manner in this family. Clinical manifestations in the examined persons and an extended family history are described in detail. Previous studies of apparently hereditary dental ankylosis are similarly discussed.

Projecting the soft-tissue outcome of surgical and orthodontic manipulation of the maxillofacial skeleton.

A simple method is presented for developing one-to-one composite soft-tissue and radiographic patient images. Their use in diagnosis, treatment planning, and prediction of the outcome of surgical and orthodontic manipulations of the facial hard tissues to effect soft tissue change is discussed. Complementing cephalometric analysis and model surgery, this technique uses a 35 mm, slide, acetate tracing paper, a pencil, and a series of integumentary changes which follow rearrangements of the underlying skeleton, including the dentition, maxillae, zygomas, and nose. The pretreatment images is traced from a projected 35 mm, slide, which is sized to the cephalometric tracing to obtain a "life-sized" representation of the face. The image is then redrawn, adjusting the dysmorphic parts to the unchanged part of the face to effect balance of the profile and restore normal contours. This recreated image is used then as an objective to which the treatment planning is directed and through which it is commonly seen that the restoration of functional and esthetic balance is a mutually supportive goal. The projected image is of value to the clinician in formulating his treatment goal, but it is more valuable in the visible expression that it gives to his mental image of the ideal outcome. Moreover, it can be readily shared with the patient, who often better appreciates the changes in contours, which he sees daily, than the commonly employed profiles of cephalometric prediction, which are basically foreign to him. The technique is discussed, as are the ratios of hard-to-soft-tissue change, with case reports for demonstration.

Use of the Abbé flap in revision of the bilateral cleft lip-nose deformity.

Use of the versatile Abbé flap for lip-nose revision of a representative adult with bilateral cleft lip and palate is reported. The deformity is discussed, and the surgical plans are developed and executed. Presented is a technique for reliably securing the lateral orbicularis oris muscle components to the philtrum, which ensures viability of the transposed flap and provides functional continuity across the midline while accentuating the philtral dimple.

Posteriorly based, lateral lingual flaps for alveolar cleft bone graft coverage.

The use of posteriorly based, lateral lingual flaps for primary oral coverage of alveolar cleft grafts is reported. These flaps offer dependable vascularity, versatility, and viable augmentation of tissue-deficient areas while avoiding the sacrifice of covering tissue from already scarred lips or maxillary surfaces.

Modified LeFort II procedure for simultaneous correction of maxillary and nasal deformities.

An approach to correction of nasomaxillary dysplasia is described. Where midfacial hypoplasia is managed by surgical anteropositioning of the affected skeletal parts, this technique permits management of the associated nasal dysmorphia as well. The one-stage correction is performed with the midfacial skeleton entirely degloved, under direct vision. Details are described, and diagnostic and treatment considerations of two patients are given.
