Abstract

Endoscopic mini-invasive treatment for sporadic trigonocephaly is becoming a widely accepted surgical treatment. In most centers this treatment is performed in association with postoperative helmeting. The aim of the present study was to review and report the authors' 11-year experience of endoscope-assisted metopic suturectomy for treatment of 62 trigonocephaly patients without helmet use. For this retrospective study, clinical data of 62 consecutive pediatric patients (age 3-8 months) were obtained from the data bank of the "Anna Meyer" Children Hospital. These patients had been diagnosed with trigonocephaly (type II and III) and undergone surgery performed with a mini-invasive endoscopic technique during the period from January 2011 to January 2022. No helmet was used postoperatively in these patients, and they were evaluated through craniometric measurements, pre-/postoperative photographs, and parents' impressions, as well as thorough clinical examinations during follow-up appointments. The mean patient follow-up period was 6 ± 1.3 years. The female/male ratio was 1:2; 52% of the patients presented with type II trigonocephaly and the remaining patients with type III. The mean age at surgery was 153 ± 44 days (5 ± 1.5 months, range 3-8 months). In 92% of the patients the surgical outcome was defined as good to excellent. However, 4 patients presented with an unsatisfactory outcome, including 1 patient with a CSF collection requiring surgical repair 2 months after the first surgery and 1 patient who developed infection of the surgical wound and needed a second surgery. In the latter patient the outcome was evaluated as satisfactory, and no sequelae regarding the infection were encountered during follow-up. According to the authors' experience, endoscopic metopic suturectomy alone, without the use of a helmet, is a valid surgical option for trigonocephaly treatment, and its application can be considered in patients of older age groups (up to 8 months). Thus, in the right patient selection context, this technique represents the treatment of choice.
