The prevalence of trigonocephaly has increased worldwide over the past 2 decades. Early identification and appropriate treatment are critical. The aim of this study is to evaluate the outcomes and the effect of metopic suture excision, perisutural frontal bone shave, and bilateral pericranial flap method on the shape of the forehead after surgical correction in infants with moderate trigonocephaly. The present study was performed as a cross-sectional study on 40 infants of 3 to 12 months old with trigonocephalus who underwent metopic suture excision and pericardial flap surgery in Mofid Pediatric Hospital from 2016 to 2022. The definitive diagnosis of patients’ trigonocephaly was made based on clinical signs and computed tomography scan findings by a plastic surgeon. Overall in 40 patients operated by this technique, 23 (57.5%) of cases were males, and 17 (42.5%) were females. The mean age of patients was 7.86 ± 2.22 months. Hospital stay was 2 to 4 days (mean: 3 d), intensive care unit admission was in 33 cases for 24 hours, and no intensive care unit admission for 7 cases. Blood was transfused during surgery for 25 patients, and 15 patients did not require blood transfusion use. Results were evaluated in 6 to 12 months after surgery by 3 independent plastic surgeons, with pre and postoperative photos. Satisfaction with the results of forehead shape was excellent for 60% of patients, good for 37.5%, and moderate for 2.5%. Only one female patient had a recurrence after the surgery. This study showed that the pericranial flap method after full metopic suture excision and frontal shave was very effective in the treatment of infants with moderate trigonocephaly.

Trigonocephaly is a craniofacial malformation caused by premature fusion of the metopic suture. Surgical correction frequently results in the need for blood transfusion. Transfusion complications include transfusion-transmitted infections (TTIs), immune-mediated reactions, and volume overload. Donor exposure (DE) describes the number of blood products from unique donors with increasing DE equating to an increased risk of TTI. We evaluate data on 204 trigonocephaly patients covering 20 years of practice with respect to blood transfusions and DE. This represents the largest series from a single unit to date. A protocol based on our experiences has been devised that summarizes the key interventions we recommend to minimize blood transfusions and DE in craniofacial surgery. Patients operated on between 2000 and 2020 were included. DE and a range of values were calculated including estimated red cell loss (ERCL) and estimated red cell volume transfused (ERCVT). Groups were established by relevant interventions and compared using the Mann-Whitney U test. Mean DE fell from 1.46 at baseline to 0.85 (P<0.05). Median allogenic transfusion volume fell from 350 mL at baseline to 250 mL (P<0.05). Median ERCL fell from 15.05 mL/kg at baseline to 12.39 mL/kg and median ERCVT fell from 20.85 to 15.98 mL/kg. Changes in ERCL and ERCVT did not reach statistical significance. DE can be minimized with the introduction of key interventions such as a restrictive transfusion policy, preoperative iron, cell saver, tranexamic acid, and use of a matchstick burr for osteotomies.

Facial bone fractures are relatively common, with the nasal bone the most frequently fractured facial bone. Computed tomography is the gold standard for diagnosing such fractures. Most nasal bone fractures can be treated using a closed reduction. However, delayed diagnosis may cause nasal deformity or other complications that are difficult and expensive to treat. In this study, the authors developed an algorithm for diagnosing nasal fractures by learning computed tomography images of facial bones with artificial intelligence through deep learning. A significant concordance with human doctors’ reading results of 100% sensitivity and 77% specificity was achieved. Herein, the authors report the results of a pilot study on the first stage of developing an algorithm for analyzing fractures in the facial bone.

Background: In patients with facial paralysis, the free functional gracilis muscle transfer is preferred for facial reanimation. The choice of an adequate motor nerve to innervate the transplanted gracilis muscle is one of the procedure’s key components. We present a comparative study between cross-facial nerve graft (CFNG) and masseteric nerve as donor nerves for reinnervated gracilis flap transfer in patients with complete facial paralysis. Materlals and Methods: Retrospective analysis was performed on all patients with complete facial paralysis who had a free functional gracilis muscle transfer for facial reanimation between January 2014 and December 2021. Only those who received gracilis transfer reinnervated by either CFNG or masseteric nerve were included in this study. The smile excursion and lip angle were measured for evaluating the outcomes postoperatively. Results: The inclusion criteria were met by a total of 21 free functional gracilis muscle transfers, of which 11 were innervated by CFNG and 10 by the masseteric nerve. Both surgical procedures resulted in a highly considerable smile excursion of the reanimated side and postoperative improvement of static or dynamic lip angle. Masseteric nerve coaptation led to greater smile excursion and more significant improvement of dynamic lip angle than CFNG. Conclusions: For patients who have complete facial paralysis, face reanimation can be successfully accomplished by free gracilis transfer reinnervated by the CFNG or the masseteric nerve. In particular, the masseteric nerve is a reliable choice for dynamic smile reanimation.
