Contralateral coronoid process bone grafts for orbital floor reconstruction: an anatomic and clinical study.

PURPOSE: This study compares the contour of the coronoid process with the orbital floor using skulls and shows the use of this bone as a graft for orbital floor reconstruction. METHODS: Measurements and contour evaluations of the orbital floor and the contralateral mandibular coronoid process (12 right orbital floors with the lateral surface of the left coronoid process and 12 left orbital floors with the lateral surface of the right coronoid processes) were made in 24 dried adult human skulls (age, race, gender unknown) to assess the feasibility of using the mandibular coronoid process for orbital floor reconstruction. Applying the findings of this study, eight patients who had sustained either an isolated orbital floor blowout fracture (n = 2) or orbital floor compromise with an associated zygomatic bone fracture (n = 6) were treated by using their contralateral coronoid process for repair of the orbital floor. RESULTS: Anatomic Study: Measurements and contour comparisons of the right orbital floor with the left lateral cortex of the coronoid process in 12 skulls and the left orbital floor with the right lateral cortex of the coronoid process in the another 12 skulls showed a close match in contour and demension. CLINICAL STUDY: Although minimal trimming of the peripheral bony margins and medial coronoid cortical plate was needed, none of the grafts required recontouring of their lateral cortical surface in the eight patients. Postoperative radiographic studies showed a correct anatomic contour of the orbital floor. A 1-year follow-up of each patient showed no occurrence of diplopia, enophthalmia, muscle entrapment, or infection. All eight patients had transient (1 to 2 weeks) trismus. CONCLUSION: Based on the anatomic studies and clinical results, the coronoid process makes an excellent donor graft site for reconstruction of orbital floor deformities.

Anatomic relationship of the genial tubercles to the dentition as determined by cross-sectional tomography.

PURPOSE: This study determined the anatomic location and the dimensions of the genial tubercles in relation to the apices of the mandibular central incisors. MATERIALS AND METHODS: Linear cross-sectional tomographic images were made of 41 adult human skulls. A 2-mm-thick section was produced through each central incisor. The vertical distance between the apex of each central incisor and the level of the superior aspect of the genial tubercle was measured on the radiographs. Additional measurements were taken on the dry skulls to determine the horizontal distance between the apices of the two central incisors and the width and height of the genial tubercle. RESULTS: Although 5 mm is considered a safe zone for geniotomies, 29 of the genial tubercles (35.4%) were less than 5 mm from the apices of the mandibular central incisors. The distance between the apices of these incisors ranged from 9 mm to 15 mm. CONCLUSION: Osteotomy of the genial tubercles can be performed within the confines of the mandibular central incisors, but care must be taken to avoid the root apices.

Avoiding problems in patients with craniotubular bone disorders.

Since osteomyelitis can occur concurrently with osteopetrosis, all craniotubular bone disorder patients should be treated carefully. We recommend preoperative antibiotic coverage and minimizing any excessive force to avoid the risk of osteomyelitis and jaw fractures when surgery is necessary.

Maxillary osteomyelitis and spontaneous tooth exfoliation after herpes zoster.

Reports of spontaneous tooth exfoliation and osteonecrosis trigeminal herpes zoster are extremely rare and have been sporadic. This article reports a pertinent case of a 50-year-old man who exhibited prodromal odontalgia before the appearance of vesicular mucocutaneous lesions, together with severe destruction of the maxillary bone and exfoliation of multiple teeth. This patient was successfully treated using a unique closed nasal-vestibular drainage system for the ultimate control of maxillary bone viability. A review and analysis of the clinical aspects and the pathogenesis of herpes zoster and bone necrosis are discussed.

Maxillary antrum hypoplasia. Report of a case.

Hypoplasia of the maxillary antrum is a rarely encountered condition. Antral hypoplasia has been misdiagnosed as sinusitis, chronic sinus infection, and neoplasm. Antral hypoplasia can be associated with difficult and unnecessary surgical explorations. A case of unilateral maxillary antrum hypoplasia is reported. Associated anatomical anomalies and a review of literature is described.

Prader-Labhart-Willi syndrome.

Prader-Labhart-Willi Syndrome is a complex, multisystem sporadic disorder which presents during childhood and proceeds into adulthood. The major features include infantile hypotonia, developmental delay, hypogonadism with abnormal sexual maturation, mental retardation and behavior abnormalities, short stature with small hands and feet, massive obesity with diabetes mellitus, dysmorphic facial features, and marked dental caries and enamel hypoplasia. Recently, a deletion of chromosome 15 has been found in a large percentage of these patients, but the exact cause and genetic transmission has not yet been determined. Two cases of Prader-Labhart-Willi Syndrome are presented with emphasis on the differential diagnosis of enamel hypoplasia associated with sexual maturation.

Seventeen granular cell lip tumors in a six-year-old boy.

A review of the literature and a rare report of a case involving multiple (17) granular cell tumors of the lips are presented. The surgical approach and management were predicted on the principles of complete surgical removal, cosmetics, and producing anatomic symmetry.
