Historically, the surgical correction of this deformity has predominantly utilized rib cartilage for ear reconstruction. This study presents a method for correcting microtia with crus helicis transversal deformity, utilizing the flap technique in conjunction with cartilage transplantation. METHODS: From February 2017 to October 2023, a total of 42 patients with crus helicis transversal deformity and microtia were included in this retrospective study. The corrective surgery combines flap technique with cartilage transplantation. We collected the morphological data of ear, Visual Analogue Scale (VAS) satisfaction scores, and Aesthetic Outcomes Scale (AOS) aesthetic ratings of patients both prior to and 12 months following surgery. RESULTS: The average duration of follow-up was 13.71 ± 2.97 months. Following the operation, there has been a significant improvement in the length, width, and circumference of the ear, as well as in the differences in these measurements between the two ears compared to prior to the procedure. The average AOS score prior to surgery was 17.90 ± 1.41, while the average AOS score following surgery increased to 29.57 ± 1.51. The preoperative VAS satisfaction score was recorded at 1.95 ± 1.12, while the postoperative VAS score showed a significant increase to 8.23 ± 0.87. CONCLUSION: The flap technique, combined with cartilage grafting, effectively corrects the crus helicis transversal deformity with microtia.

Thirty standardized profile images combining three Li-Sbl angles (30°, 45°, 70°) with five Lia-Pog′ angles (0°–40°) were evaluated by 270 assessors (maxillofacial surgeons, orthodontists, skeletal Class II patients, laypeople) for aesthetic perceptions and surgical recommendations. RESULTS: Gender-specific optimal configurations were identified: females achieved highest scores (7.81–8.19) at Li-Sbl 45°/Lia-Pog′ 20°; males at Li-Sbl 45°/Lia-Pog′ 10°–20° or Li-Sbl 70°/Lia-Pog′ 0° (6.31–7.60).

Although osteomyelitis has been reported in association with LS, delayed-onset chronic mandibular osteomyelitis occurring after completion of LS treatment is exceedingly rare. CASE PRESENTATION: A 16-year-old previously healthy male developed LS following odontogenic infection, complicated by septic thrombophlebitis of the external jugular and facial veins and septic pulmonary emboli. After surgical drainage and antibiotic therapy, clinical recovery was achieved. However, during post-treatment follow-up, radiographic evaluation revealed chronic osteomyelitis involving the entire mandible including both condyles. Extended antimicrobial therapy and close radiologic surveillance resulted in stabilization of the osteolytic changes and functional recovery. CONCLUSION: This case highlights a rare presentation of delayed-onset mandibular osteomyelitis as a sequela of Lemierre’s syndrome.
