“…Khan et al (2010) reported maxillary artery passed through the inferior alveolar nerve, splitting it into superficial and deep divisions in 3 of the 50 ITF fossas dissected. The first and second parts of the MA usually passed through the lateral aspect of lateral pterygoid muscle, with the inferior alveolar nerve, lingual nerve and buccal nerve on the medial side of the maxillary artery as reported by Kim et al (2010). There are also reports by Pretterklieber et al (1991) of unilateral variations of the IAN in the following forms: the MA, in addition to piercing the IAN, pierced LN and located deep to BN; the MA pierced only the IAN but passed deep to both the LN and BN; and the IAN formed a common trunk with the LN, which was pierced by the MA and ran deep to the BN.…”

La fosa infratemporal es un área anatómica clínicamente importante para la administración de agentes anestésicos locales en odontología y cirugía maxilofacial. Fueron estudiadas variaciones en la anatomía del nervio alveolar inferior y la arteria maxilar en la disección infratemporal. Durante la disección rutinaria de la cabeza en el cadáver de un varón adulto, fue observada una variación excepcional en el origen del nervio alveolar inferior y su relación con las estructuras circundantes. El nervio alveolar inferior se originaba en el nervio mandibular por dos raíces y la primera parte de la arteria maxilar estaba incorporada entre ambas. El origen embriológico de esta variación y sus implicaciones clínicas es debatido. Dado que la arteria maxilar transcurría entre las dos raíces del nervio alveolar inferior, y el nervio estaba fijado entre el foramen oval y el foramen mandibular, el atrapamiento vásculo-nervioso pudo causar entume-cimiento o dolor de cabeza e interferir con la inyección de anestésicos locales en la fosa infratemporal. Variaciones anatómicas en esta región deben ser tenidas en cuenta, especialmente en casos de tratamiento fallido de neuralgia del trigémino. Infratemporal fossa is clinically important anatomical area for the delivery of local anesthetic agents in dentistry and maxillofacial surgery. Variations in the anatomy of the inferior alveolar nerve and maxillary artery were studied in infratemporal dissection. During routine dissection of the head in an adult male cadaver an unusual variation in the origin of the inferior alveolar nerve and its relationship with the surrounding structures was observed. The inferior alveolar nerve originated from the mandibular nerve by two roots and the first part of the maxillary artery was incorporated between them. An embryologic origin of this variation and its clinical implications is discussed. Because the maxillary artery runs between the two roots of the inferior alveolar nerve, and the nerve was fixed between the foramen ovale and mandibular foramen, neurovascular entrapment may cause pain numbness or headache and may interfere with the injection of local anesthetics into the infratemporal fossa. Anatomical variations in this region should be kept in mind, particularly in cases of failed treatment of trigeminal neuralgia.

“…In the anatomical study by Rosano et al 2 , the distance between alveolar crest and PSAA was measured as 11.25 mm. In Kim et al 12 's study, it was measured as 18.90 mm in the second premolar region and as 15.45 mm in the second molar region, and it was found that age and gender did not affect this distance. In our study, the distance of PSAA to the alveolar crest was found to be higher than the values in the literature and the mean value was found as 21.99 ± 4.59 mm.…”

“…In their study they conducted by using CBCT, Kim et al 12 reported the prevalence of PSAA as 64% in men and as 40% in women and they reported a signi cant correlation between gender and the prevalence of PSAA. On the contrary, no statistically signi cant correlation was found between the prevalence of PSAA and the gender of the participants (p = 0,603).…”

Aim: The aim of this study is to evaluate the prevalence, localization and diameters of Posterior superior alveolar artery (PSAA), one of the branches of maxillary artery, and Infraorbital foramen (IOF) through which the Infraorbital artery (IOA) passes, by using conic beam computed tomography (CBCT) in dentate patients. The study also aims to research whether there is any relationship between PSAA, which has a small diameter and which sometimes cannot be seen on CBCT, and IOF, which has relatively larger diameter, in terms of size, shape and localization and to predict their location relative to each other in surgical procedures involving the maxillary sinus in edentulous patients. Material and Method: Bilateral maxillary sinuses were analysed retrospectively in CBCT images taken for various reasons from 170 patients with no missing teeth in the maxillary posterior region. Demographic characteristics of patients such as age and gender and their radiological findings were recorded. The largest locations of PSAA and IOF in the maxillary sinus were determined and their size, shape, localization in relation to the teeth and their distances from anatomical points such as the midline, medial wall and base of the maxillary sinus and crest were evaluated. Results: While 49.42% of the participants were male, 50.58% were female and mean age was 28.88 ± 9.95. The incidence rate of PSAA on CBCT was found as 56.2%. While the rate of those with a vertical diameter of ≥1 mm was 92.1%, the rate of those with a horizontal diameter of ≥1 mm was 65.4%. When the relationship of PSAA with the maxillary sinus was examined, the most common location was intraosseous with 60.2%. In terms of localization, the highest rate was found in the distal of the second molar with 34.6%. IOF was observed in all CBCT images (100%). Mean horizontal diameter of IOF was found as 3.47 mm, while its mean vertical diameter was found as 3.68 mm. In terms of shape, the most common shape was semi-circular (49.4%). In terms of localization, the most common location was at the second premolar tooth level with a rate of 39.7%. While IOF was mostly seen at the first premolar tooth level in young participants, it was mostly seen at the distal of second premolar tooth in old age. No statistical correlation was found between the diameters, localizations and shapes of PSAA and IOF (p>0.05). However, the median values of horizontal diameter, vertical diameter, distance to the midline, distance to the medial wall and base of the maxillary sinus and distance to the crest were found to be higher in men when compared to women in both anatomical structures. Conclusion: According to the results of this study, in order to prevent a possible bleeding that can occur since PSAA and IOF diameters are higher in men than women and since the vertical and horizontal diameters of PSAA are higher than 1 mm in a great majority of the patients, clinicians are recommended to evaluate the size and localization of these anatomical structures with CBCT before surgical procedures, especially in male patients and older patients. In the present study, no statistical correlation was found between PSAA, one of the branches of maxillary artery, and IOF, through which IOA passes, in terms of characteristics such as localization, distance to anatomical points and shape and our hypothesis of predicting their position relative to each other in surgical procedures of the maxillary sinus in edentulous patients was not confirmed. It may be useful to conduct more detailed studies with higher resolution CBCT devices in which more patients are included.

“…Эту артерию, в зависимости от отноше-ния к латеральной крыловидной мышце, условно принято разделять на 3 отдела: нижнечелюстной крыловидный, проходящий снаружи или кнутри (82 и 18% соответствен-но, по данным J. Kim и соавт. [24]) от латеральной крыло-видной мышцы, и крылонебный, располагающийся в крылонебной ямке и имеющий большую анатомическую вариабельность. Изучению клинической анатомии кры-лонебного сегмента ВЧА посвящен ряд анатомических исследований, что продиктовано развитием эндоскопиче-ской хирургии с разработкой методов дистального кон-троля ВЧА при удалении краниофациальных опухолей.…”

ОБЗОРЫОпухоли основания черепа, распространяющиеся в глазницу, полость носа, околоносовые пазухи, подвисоч-ную и крылонебную ямки (далее краниофациальные), -это новообразования различной гистологической приро-ды как доброкачественной, так и злокачественной, удале-ние которых часто сопровождается обильной кровопоте-рей. Причиной этого являются особенности кровоснаб-жения, осуществляемого из разных сосудистых бассейнов. На сегодняшний день краниофациальные хирурги распо-лагают большим арсеналом диагностических и лечебных возможностей, а основными принципами краниобазаль-ной хирургии являются стремление к максимальной ради-кальности удаления опухолей с минимизацией послеопе-рационного функционального дефицита.Послеоперационные функциональные осложнения могут быть представлены нарушениями зрения, глазодви-гательными симптомами, трофическими нарушениями глазного яблока, дистрофией и спазмом жевательной му-скулатуры, патологическими изменениями слизистой носоглотки, околоносовых пазух и др. [1-3], а их основ-ными причинами являются механическое повреждение тканей в результате хирургической манипуляции и нару-шение кровоснабжения из-за повреждения питающих нормальные структуры сосудов, особенно таких конеч-ных не анастомозирующих артерий, как центральная ар-терия сетчатки, цилиарные артерии и др. Вероятность развития послеоперационных нарушений существенно возрастает на фоне интенсивного кровотечения во время удаления опухоли.Таким образом, основным путем минимизации по-слеоперационного дефицита и интраоперационного кро-вотечения является планирование техники хирургическо-
