ABSTRACT

OBJECTIVE: Facial resurfacing with a CO2 laser has been used for treatment of pathologic lesions and for cosmetic purposes. Postoperative complications and problems after laser resurfacing include infections, acneiform lesions, and pigment changes. This retrospective study describes the most common problems and complications in 105 patients and assesses postoperative pain in 38 patients. STUDY DESIGN: All patients received CO2 laser resurfacing for treatment of malignant/premalignant lesions and had postoperative follow-up to assess problems and complications. Some had follow-up to assess postoperative pain. All patients had Fitzpatrick I-III skin types and underwent the same perioperative care regimen. RESULTS: There were 11 problems and 2 complications. Problems included infection, acneiform lesion/milia, and uncontrolled postoperative pain. Complications included hyperpigmentation. Among the postoperative pain group, 53% reported no pain and the rest had mild or moderate pain. CONCLUSION: Complications are rare. Infection and acneiform lesions/milia were the most common problems, as previously reported. Most patients do not experience postoperative pain.

ABSTRACT

PURPOSE: To characterize the anatomic course of the mandibular incisive canal to define parameters for harvesting autogenous bone from the symphysis of the mandible. MATERIALS AND METHODS: A series of osteotomies were completed between the mental foramina in the anterior mandibles of 19 cadavers. Methylene blue dye was used to help identify the incisive canal. From the canal, distances to key adjacent landmarks were measured with a Boley gauge to 0.1 mm. Measurements included distances from the mandibular incisive canal to the buccal cortex, the lingual cortex, the inferior border of the mandible, the apices of the teeth, and the buccal cementoenamel junction (CEJ) of the teeth. RESULTS: The canal decreased in diameter from lateral to medial. It tended to be closer to the buccal cortical bone than to the lingual cortex (P < .001) and was, at times, directly abutting the buccal cortex (average distance to buccal cortex, 3.5 mm). The canal maintained a relatively constant distance from the apices of the teeth (approximately 7 to 8 mm), coursing inferiorly under the longer canines bilaterally. The canal became increasingly difficult to identify toward the midline, likely dispersing into microscopic tributaries. CONCLUSIONS: The authors suggest several modifications to the standard surgical approach to the symphysis area during the harvest of bone grafts. When the goal is to avoid the mandibular incisive canal, osteotomies should not exceed a depth of 4 mm, should be at least 5 mm anterior to the mental foramen, and 9 mm below the root apices (or 23 mm below the lowest facial CEJ) and should maintain the contour of the mandible's inferior border. Alternatively, some degree of canal compromise can be accepted and larger grafts can be obtained by increasing the depth of the harvest in the horizontal dimension or decreasing the distance from the osteotomy to the root apices (or the CEJ) in the vertical dimension.

ABSTRACT

PURPOSE: Head and neck neoplasms requiring surgical resection of the mandible can have negative consequences on patient quality of life. For patients with segmental resections, the vascularized fibular free flap and nonvascularized iliac crest are frequently used. The fibula has surpassed the iliac crest in popularity due to the success associated with a vascularized graft; however, there still remain significant advantages with the nonvascularized graft. There has not been a study comparing the quality of life associated with these two methods of mandibular reconstruction. We carried out the following study to compare quality of life of both grafts in an attempt to help guide therapeutic decisions. PATIENTS AND METHODS: Twenty-nine patients at the University of California, San Francisco undergoing mandibular resection with subsequent reconstruction with either a vascularized fibular free flap or nonvascularized iliac crest bone graft were identified. Patient quality of life was assessed with a modified version of the University of Washington Quality of Life Questionnaire, version 4. RESULTS: Eighteen patients responded (10 reconstructed previously with a fibula, 8 with iliac crest reconstructions). Patients with an iliac crest bone graft had significantly better chewing and swallowing scores (P = .04, P = .049 respectively). There was also a trend for better taste (P = .067). When patients with a history of radiation therapy were excluded, differences in chewing and swallowing were not significant (P = .26 and P = .31 respectively), whereas taste was (P = .038). CONCLUSIONS: These findings suggest that reconstruction with the iliac crest had benefits in improved function (chewing, swallowing, and taste) rather than esthetics, donor site morbidity, or psychologic discomfort as was anticipated. However, prior radiation, a relatively frequent therapy in this patient population, presents an important confounding factor. Radiation therapy is difficult to control for without limiting an already scarce patient pool, and bears with it significant morbidity that likely influenced these findings. Further study is warranted to confirm the results and further distinguish the 2 groups.
