Background The aim of this study was to evaluate the influence of two harvesting approaches on the donor site vascular injury. Methods A split‐mouth cadaver study was designed on 21 fresh donor heads. Every hemi‐palate was assigned to receive the trap‐door harvesting technique (TDT) or the epithelialized free gingival graft harvesting technique (FGGT). A soft tissue graft was harvested from each side for histology analyses. Betadine solution was used to inject the external carotid artery and a collagen sponge was positioned over the harvested area to compare the amount of “leakage.” Results The mean leakage observed was 16.56 ± 3.01 µL in the FGGT‐harvested sites, and 69.21 ± 7.08 µL for the TDT group, a ratio of 4.18 (P < 0.01). Regression analyses demonstrated a trend for more leakage at thinner palatal sites for the FGGT group (P = 0.09), and a statistically significant correlation for the TDT‐harvest sites (P = 0.02). Additionally, a shallow palatal vault height (PVH) was associated with a higher leakage in both harvesting groups (P = 0.02). The histomorphometric analyses revealed that grafts harvested with TDT exhibited a significantly higher mean number of medium (ø = 0.1 to 0.5 mm, P = 0.03), and large vessels (ø ≥ 0.5 mm, P = 0.02). Conclusions Within the limitations of the present research, the TDT resulted in a significantly higher leakage than the FGGT, which was also correlated with the histology analyses where a greater number of medium and large vessels were observed in the harvested grafts.

“…The observed inconsistency could have resulted from each cadaver’s vascular properties (such as the degree of atherosclerosis), a clot blockage, or the injection technique. Two studies in which injections were administered through both sides of the CCA had promising results [ 5 , 13 ]. Thus, two-sided injections with a peristaltic pump force should be further investigated.…”

“…We found 18 studies that used latex, nine studies that used silicone, and three studies that used gelatins. The injection volumes ranged from 100 to 180 mL per head [ 5 , 7 , 13 , 19 , 20 ]. The injection vehicles were Foley catheter, soft plastic tube, hypodermic syringe, plastic suction tubes, and nasogastric tube [ 1 , 5 , 7 , 21 ].…”

Latex-injected, non-decapitated, saturated salt method-embalmed cadaver technique development and application as a head and neck surgery training model

Published cerebrovascular injection techniques have mostly used decapitated, fresh cadavers or heads embalmed with 10% formaldehyde. There have been no reports using vascular-injected cadavers for head and neck surgical training models or using vascular injections in saturated salt method-embalmed cadavers. Thus, we performed vascular labeling of five saturated salt method-embalmed cadavers without decapitation. Latex mixed with red ink was injected into the common carotid artery via a 3D-printed vascular adapter. The injection force was provided by a peristaltic pump. Thyroidectomy, submandibular gland excision, neck dissection, parotidectomy, and mandibulotomy were performed on both sides of each cadaver (n = 10). The consistency of the cadavers was softer than fresh ones. Subcutaneous tissues were well preserved, and muscles were moist and elastic. Five physicians graded the resemblance of the heads and necks of the latex-injected, saturated salt method-embalmed, non-decapitated of five cadavers compared to living humans using a Likert scale from 0 (no resemblance) to 5 (maximum resemblance). Fifty-two percent of the head and neck region resemblance scale ratings were four or five. Although the cadavers were practical for head and neck surgical simulations, the brain parenchyma was only partially preserved and unsuitable for use. The most distal arterial branches reached by the injected latex were measured. The external caliber of the smallest vessels reached were lacrimal arteries (mean caliber ± SD, 0.04 ± 0.04 mm; 95% CI [0, 0.09]). There were no significant differences in the mean caliber of the smallest vessels reached between the left- and right-sided arterial branches (all p < 0.05).

The maxillary sinus, the largest of all paranasal sinuses, is shaped like a pyramid, with dimensions of approximately 2.5 cm in width, 3.75 cm in height, and 3 cm depth. 1 When patients lose teeth in the posterior maxilla, alveolar bone resorption follows, both centripetal, as a consequence of the physiological bone remodeling following tooth loss, and also from sinus cavity pneumatization toward the alveolar crest. 2 These two processes usually result in limited bone availability for implant placement, hence requiring a regenerative procedure, the so-called maxillary sinus lifting procedure. Sinus lifts are currently considered a safe treatment modality with a low complication rate. 3,4 The procedure is referred to in different ways in the literature, as sinus lift, sinus augmentation, sinus floor elevation, or augmentation of an atrophic maxillary sinus. Since the objective of this regenerative intervention is to provide sufficient bone height and width for appropriate implant placement, dental implants may be placed at the same time as the sinus augmentation procedure ("one-stage" technique). The alternative is a staged procedure, where the bone is augmented during the first surgical intervention and then the dental implants are placed after the appropriate bone volume has been created ("two-stage" technique).

Vascular Structures of the Lateral Wall of the Maxillary Sinus

Abstract: The vascular labeling technique detects maxillary sinus vessels in a predictable and effective way. These structures are clinically relevant because they are located in the area where the lateral window is usually created in sinus augmentation procedures and can cause profuse bleeding.
