"Nasal lining rotation flap with triangular fossa composite graft, an effective method for managing the multiply-revised Asian short nose".

BACKGROUND AND OBJECTIVES: Postoperative short nose is one of the most difficult problems encountered in plastic surgery. We propose a technique of lining rotation flaps combined with composite chondrocutaneous auricular graft from the triangular fossa to reconstruct the lining defect and improve surgical results. METHODS: Twenty patients were operated on between 2016 and 2019 for postoperative short nose. Lining rotation flaps were used to supply missing medial mucosal lining with creation of a raw surface at the lateral lining in 10 patients (intervention group). A total of 17 composite chondrocutaneous grafts taken from the triangular fossa of the ears were used to resurface the defect. The other 10 patients received lining management using conventional techniques (control group). RESULTS: There was a near-complete take of 13/17 composite grafts (76.5%), with four partial losses that healed uneventfully. Anthropometric analysis of preop and postop profile photos showed statistically significant decreased nasolabial angle in both groups. The amount of derotation achieved was significantly increased (p < 0.05) with our proposed method (Intervention group: 12.3 ± 9.3° vs. control group: 6.55 ± 4.5°). Donor sites healed uneventfully. Both groups of patients were satisfied with their results based on Rhinoplasty Outcomes Evaluation questionnaire. CONCLUSIONS: The lining rotation flap with triangular fossa composite graft is a safe and effective method for management of the postoperative short nose in Asians.

Clinical outcome following intraoperative computed tomography-assisted secondary orbital reconstruction.

BACKGROUND: Secondary post-traumatic orbital reconstructions are challenging. Portable computed tomography (CT) provides the option to acquire real-time, intraoperative images that help to detect the insufficient reconstruction of the orbit immediately. We retrospectively analyzed patients who received intraoperative CT imaging and analyzed the effect of intraoperative CT scans on revision rates and orbital volume changes before, during, and after surgery. METHODS: From August 2014 to September 2016, eleven patients received intraoperative cone-beam CT scans to evaluate the results of secondary orbit reconstruction using Medpor + titanium implants. Patient demographics, surgical details, CT scanning protocol, and follow-up results were analyzed. 3D CT volumetry was used to analyze the orbital volume based on OsiriX MD software. RESULTS: Based on intraoperative CT findings, seven cases required intraoperative revision to further augment the orbital cavity or adjust implants. The mean preoperative measured enophthalmos was 3.41±1.4 mm (range: 2-6 mm), which decreased to 0.73±0.4 mm (range: 0-1 mm) at postop assessment (p<0.0001). On the fracture side, there was a significant difference between preoperative vs. intraoperative and preoperative vs. postoperative volume measurements (p<0.01 for both subsets), but no significant difference between intraoperative vs. postoperative measurements. CONCLUSION: Intraoperative CT is a valuable tool in secondary orbital reconstruction cases based on clinical enophthalmos evaluation and 3D CT volumetry. For these patients, the avoidance of another revision surgery may outweigh the disadvantage of increased operation time and additional radiation exposure.
