“…The asterion type found in Thai female cadaveric skulls was similar to males, where the occurrence of asterion type II is followed by asterion type I. As well as in Thais, the asterion type II was always the most found in several ethnicities, including Turks (Ucerler & Govsa, 2006), Kenyans (Mwachaka et al, 2010), Indians (Singh;Pavan et al, 2015;Deepak & Dakshayani, 2015), and Iranians (Gharehdaghi et al, 2020) (Table IV). However, the occurrence of asterion type I in the Thai population was significantly higher than those studied in other races.…”

The asterion is the joining of the lambdoid, parietomastoid, and occipitomastoid sutures. It is classified into two types, type I shows small bones or woven bones, while in type II, woven bones are non-existent. In this study, forty cadavers were conducted and observed the asterion on both sides of skulls showing the approximate ratio of type II and type I was 3:2. The asterion was located by measuring the distances from the asterion to skull landmarks, including inion, the root of zygoma, and mastoid tip. The mean distance between asterion and inion was 62.9 ± 6.0 mm. The mean distance between asterion and the root of zygomatic arch was 58.3 ± 6.1 mm, whereas the mean distance between asterion and mastoid tip was 51.1 ± 5.3 mm. The most common location related to the asterion was the dural venous sinuses on 65 % of tested sides, followed by infratentorial dura and supratentorial dura (25 % and 10 %, respectively). However, the authors found no differences between sexes, sides, and types in any underlying structures.

“…17 This presence of sutural bone is used to classify the asterion into type I (with sutural bone) and II. [18][19] However, the prevalence of type I asterion was round 10-20% and generally not mentioned in anatomical studies for surgical purposes. [1][2][3][4][5][6][7][9][10][15][16] Since the aim of our study was practical usage, we used only conspicuous suture lines.…”

Temporal Bone Landmarks of the Transversesigmoid Sinus Junction: An Anatomical Study in Dried Human Skulls

Objective: To investigate the accuracy in localization of the anterosuperior margin of TSSJ by using the intersection point between the squamosal and parietomastoid sutures (A point) and the intersection of the squamosal suture and supramastoid crest (B point) as bony landmarks.Materials and Methods: The A and B points were marked on the inner surface of a skull by using the transillumination technique. The anatomical relationship between the projected A point, B point, and groove of TSSJ was investigated in 60 dried Thai human skulls (120 sides).Results: Of the 120 sides, the projected A points were located exactly on the anterosuperior margin of the TSSJ in 38 (31.7%) instances and adjacent (above and below) the anterosuperior margin in 82 (68.3%) cases. Of the 118 sides with identifiable supramastoid crests, the projected B points were located precisely on the anterosuperior margin of TSSJ in 60 (50.8%) cases and above the anterosuperior margin of the TSSJ in 57 (48.3%) cases. Hence, the projected B point was a more reliable bony landmark for localizing the anterosuperior margin of the TSSJ when compared with the projected A point (p = 0.003, OR 2.2, and 95% CI =1.3-3.8).Conclusion: The B point is a more reliable temporal bone landmark for localization of the TSSJ than the A point. In temporal craniotomy, an initial burr hole at the B point is relatively safe and carries a very low risk of inadvertent venous sinus injury.

“…One of the inevitable complications of scalp incision is scarring and loss of hair follicles in the cut area. Since paying attention to the aesthetic aspects of the patient's head after surgery is very important for the patient's mental health and social life, surgeons should try to adopt a method that minimizes damage to the scalp and follicles, heals the wound in the fastest and most possible way and minimizes the extent of the incision area [9,10].…”

“…It is recommended to minimize the aesthetic effect with a step-by-step method [4][5][6][7][8]. Since paying attention to the aesthetic aspects of the patient's head after surgery is very important for the patient's mental health and social life, surgeons should try to adopt a method that minimizes damage to the scalp and follicles, heals the wound as soon as possible and reduces the extent of the incision area [9][10][11]. The aim of this study was to compare the 2 incision methods mentioned in terms of aesthetics and patient satisfaction and also their effect on the density of hair follicles of surgical site scalp.…”

Cosmetic Outcomes of Scalp in Standard Reverse Question Mark Incision and L.G. Kempe Incision in Large Craniotomies

Background and Aim: Craniotomy is a surgery in which a flap of the skull is opened to access the affected area in the brain. Since paying attention to the aesthetic aspects of the patient’s head after surgery is very important for the patient’s mental health and social life, surgeons should try to adopt a method that minimizes damage to the scalp and follicles. Methods and Materials/Patients: In this clinical trial study, patients who were candidates for frontotemporoparietal craniotomy surgery were selected. Twenty-three selected patients were randomly divided into 2 groups consisting of a 12-member intervention group (L.G. Kempe) and an 11-member control group (Standard Reverse Question mark). Patients underwent a pre-operative biopsy of the scalp and a follow-up biopsy 6 months post-operatively. In the evaluation of aesthetic aspects, the created scar was scored using the Stony Brook Scar Evaluation Scale (SBSES). Patients were also directly asked about their satisfaction with the operation and the scar created. Results: In 23 patients, the results showed that patients who underwent LG Kempe incision craniotomy received significantly higher scores in SBSES scoring evaluations (P=0.005). There was no significant difference in subjective evaluations by asking patients about their satisfaction with the scar site and the operation area (P=0.75). In the analysis of post-operative hair follicle density between the 2 groups (P=0.910), general changes in pre-operative and post-operative follicle density in all samples (P= 0.657) as well as comparing the changes between 2 groups, no significant difference was found between follicular density changes between the intervention and control groups (P=0.137). Conclusion: Patients treated with L.G. Kempe incision had significantly higher SBSES scores, which can be considered an aesthetically superior method that could prevent the formation of undesirable scar.
