Morbidity of chin bone harvesting

Abstract

The chin is a very common donor site for autogenous bone grafts. The aim of this retrospective study was to evaluate long-term morbidity of the donor site following chin bone graft harvesting. One to three years after grafting of local bone defects of the anterior maxilla with chin bone, 21 patients were recalled for objective assessment of any residual morbidity at the harvesting area. Morbidity as well as satisfaction of the patients were evaluated by a survey of the medical record, a mail-in questionnaire, and a standardized physical examination. The outcome of this study showed that there was good acceptance of the chin bone harvesting procedure. The objective morbidity was low, but subjectively almost half of the patients reported a changed (decreased) sensibility in the harvesting area. This subjective change in sensibility did not result in noteworthy complaints or discomfort by the patients, however. Although bone harvesting from the chin is generally considered as a good option for reconstruction of local bony defects, the patients should be informed about the potential hazard of a changed sensibility in the chin region.

Estudio Radiográfico Prospectivo de la Reparación Ósea en Sínfisis Mandibular Posterior a la Remoción Ósea de Mentón

“…Anatómicamente, esta región presenta estructuras importantes a considerar como los forámenes mentales con su paquete vascular y nervioso mental, músculos mentales y raíces dentarias (Montazem et al), lo que justifica buena parte de las complicaciones y secuelas de esta cirugía. De esta forma, se ha identificado complicaciones postoperatorias como la parestesia regional, lesiones a rices dentarias, ptosis de labio, alteraciones en el contorno facial, entre otras (Raghoebar et al, 2001;Sbordone et al, 2009), que exigen del cirujano un amplio conocimiento de la técnica y de las condicionantes anatómicas del sector.…”

Cuando se retira el hueso necesario, permanece un defecto en sínfisis que posteriormente debe repararse; de esta forma, el objetivo de esta investigación es identificar la reparación ósea existente en sínfi-sis mandibular luego de retirar un bloque óseo para reconstrucción alveolar.…”

Histological and Clinical Survey of Polylactic-Polyglycolic Acid and Dextrane Copolymer in Maxillary Sinus Lift: A Pilotin VivoStudy

“…Many reports in literature cite autogenous bone as the sinus filler of choice because of its osteoconductive and osteoinductive properties (4). The iliac crest is the most frequent extraoral site for harvesting autogenous bone, while the most often used intraoral sources are the chin and mandibular ramus (5).…”

“…Many drawbacks to generalized use of these donor sites have been described (5)(6), therefore, harvesting protocols might be reserved for subjects requiring more extensive reconstructive procedures in multiple oral regions, rather than a single sinus lift.…”
