    The adipose body of cheek is the tissue located in the buccal space. In the past, the partial removal of this tissue, called jugal lipectomy, was indicated to fill defects resulting from buccosinusal communications and/or maxillary resections. Recently, such technique became popular in facial aesthetics as it gives patients the feel of a more delicate face, in which the zygomatic bone appears to be more prominent due to the reduction in the volume of the cheeks. However, many professionals are unaware of how to establish the correct diagnosis of facial volume alterations, as well as in performing and treating the complications that may arise from jugal lipectomy. The aim of this paper is to present three clinical cases with different applications of jugal lipectomy, discussing some relevant aspects of surgical planning that involve the request for imaging exams and a previous study of this tissue’s anatomical features.


    Although previous studies on adipose body of cheek (ABC) have been brief and scarce in the literature, there is currently a greater interest by researchers in studying the anatomy of this support tissue, considered as an important factor influencing facial aesthetics[1].

    The ABC, also known as the “Bichat ball”, was described in 1802 by French physiologist and anatomist Marie François Xavier Bichat, father of modern histology. Histologically, the tissue is composed of the same type of fat present in other parts of the human body and is one of the last reserves to be consumed during weight loss[2].

    This adipose tissue is wrapped by a thin fibrous capsule that isolates it from other structures, divided into anterior, intermediate, and posterior lobes, fixed by six ligaments inserted in the maxilla, posterior region of zygoma, inner and outer rim of infraorbital fissure, temporal tendon, and buccal membrane. The anatomy of the ABC extension is complex and fills the space between the masticatory muscles (masseter, medial pterygoid, lateral pterygoid, and temporal). The posterior lobe presents four processes (buccal, pterygoid, pterygopalatine, and temporal), keeping a close relationship with blood vessels, branches of facial nerve, and the parotid duct The parotid duct and zygomatic and buccal branches of the facial nerve cross the anterior and lateral surfaces of the ABC. The anterior surface of the ABC is covered by buccal branches of the facial nerve, while the lateral border is covered by zygomatic branches in almost all patients[3].

    Currently, the partial removal of this tissue is no longer restricted to functional indications for the correction of buccal defects, representing one of the most desired surgical procedures by patients in aesthetic clinics. However, many professionals are unaware of how to establish the correct diagnosis of facial volume alterations, as well as in performing and treating the complications that may arise from jugal lipectomy.

    Clinical evaluation has been used as the sole method to indicate the surgical procedure. However, it is known that complementary exams such as computed tomography, magnetic resonance imaging, and ultrasonography can improve the diagnosis, avoiding unnecessary surgeries. They may be employed alone or in association, and there is no consensus about the best imaging modality. Thus, the aim of this paper is to present three cases with different clinical applications, highlighting the importance of anatomical and imaging knowledge for better planning and execution of the surgical technique.

    Case report

    Case 1

    A female patient, 24 years old, sought the service of maxillofacial surgery complaining of a chronic bite of the bilateral jugal mucosa and aesthetic dissatisfaction with excessive cheek volume. She reported good health status and absence of systemic alterations. A facial examination revealed a rounded face [Figure 1] associated with the suspicion of masseter hypertrophy, which was discarded after palpation of the musculature and request for imaging exams. An intrabuccal examination revealed the presence of a white line of keratinization, asymptomatic, parallel to the occlusion line, suggestive of an alba line [Figure 2]. Doppler ultrasound revealed symmetry of the ABC on the right and left sides and a very close relationship of the branches of arteries and buccal veins on both sides [Figure 3].

    Figure 3. Doppler ultrasonography on the right (A) and left (B) sides, showing blood vessels over the surgical area

    Jugal lipectomy was performed under local anesthesia, using 2% lidocaine and 1:100,000 epinephrine, and a parallel incision was made immediately adjacent to the mucosal bite line. The access distance was at least 1 cm below the parotid caruncle and could have been extended up to 2 cm. It is recommended to start the incision 1 cm behind the caruncle, avoiding trauma in the masseter muscle. After submucous divulsion, a portion of the ABC was identified along with blood vessels, which were linked with 4-0 silk thread [Figure 4]. Next, part of the buccal extension of the ABC was pulled by rotating movements by a Halstead forceps to remove the tissue and the mucosa was sutured with 3-0 silk thread. To prevent edema, 8 mg of dexamethasone was prescribed 1 h before surgery. After surgery, 750 mg of paracetamol every 6 h and 100 mg of nimesulide every 12 h were prescribed for three days for pain control.

    Patient is in the second postoperative year with no complaint of biting jugal mucosa.

    Case 2

    A female patient, 29 years old, sought the service of maxillofacial surgery complaining of facial asymmetry and reporting good health status and absence of systemic alterations. Facial examination revealed a slight increase in volume in the cheek region on the left side. Intraoral examination showed an unevenness of the occlusal plane and class I occlusion [Figure 5]. Magnetic resonance imaging did not identify alterations in bone tissue, such as condylar hyperplasia, and/or changes in soft tissue, such as masseter hypertrophy and/or temporomandibular joint disorders [Figure 6]. The surgical technique was the same used in the first reported case, removing 2.8 mL of fat from the buccal extension of the left ABC. In addition to the pre- and postoperative medications, a compressive dressing was performed to better control edema. After four months of follow-up, the patient is satisfied with the facial contour and better symmetry in the region of upper lip and the wing of the nose [Figure 7].

    Case 3

    A male patient, 22 years old, sought the service of maxillofacial surgery complaining of passage of liquid from the oral cavity to the nasal cavity during feeding. In the anamnesis, he reported good health, absence of systemic alterations, and a history of tooth extraction 3 months ago. Facial examination showed palpation sensitivity in the region of the right maxillary sinus associated with a buccosinusal fistula with active drainage of purulent secretion [Figure 8]. Waters view radiography identified a suggestive image of generalized thickening of maxillary sinus mucosa, which was confirmed by nasal endoscopy and lead to the diagnosis of maxillary sinusitis on the right side [Figure 9].

    Figure 8. Intraoral photographs showing the buccosinusal fistula

    Figure 9. Waters view radiography showing opacification of the right maxillary sinus

    After remission of chronic sinusitis and treatment with hydration, systemic antibiotic therapy, and nasal decongestant, the surgery was scheduled to close the fistula [Figure 10]. Given that it required a small amount of adipose tissue, a 1-cm gingivobuccal incision was performed, located 1 cm above the parotid caruncle. After divulsion, a non-pedicled portion of the ABC was removed, transferred, and sutured over prior fistulectomy surgery. The sliding palatal flap was then positioned and sutured onto the ABC. After four months of follow-up, a healthy mucosa was observed and there were no signs suggesting maxillary sinusitis.

    The anatomy of ABC has been investigated by several authors, and few studies have made a careful analysis of tissue dimensions and volumes with the aid of imaging exams[4-6]. Loukas et al.[7] (2006) measured the ABC of 20 cadavers through computed tomography (CT) and magnetic resonance imaging (MRI), concluding that the mean volume in men was 10.2 and 8.9 mL in women, weighing approximately 9.7 g. No significant differences between genders was observed.

    As reported in the first case, a third imaging examination may be required for the study of ABC anatomy: ultrasonography (USG). This exam is based on the transmission of sound waves and reflection of these waves when they reach an interface between tissues of different densities. It is an easy-to-perform, non-invasive exam with no image superimposition, does not use ionizing radiation, and has a relatively low cost compared to CT and MRI[8]. Because it is less widespread in maxillofacial surgery, there is a shortage of qualified professionals to perform the exam and interpret the images.

    In attempt to improve such imaging findings, Jaeger et al.[9] (2016) presented a protocol for predicting the anatomy of buccal extension of ABC using USG. It was possible to identify tissues of small, or even the absence of, buccal extension, contraindicating jugal lipectomy and avoiding unnecessary surgeries. In the first reported case, we used the USG exam similarly to these authors, finding a symmetry of buccal extensions of ABC on both sides, with a volume of 2.4 mL on the right side and 2.2 mL on the left side. In the second case, the ABC volume calculated from MRI showed a difference of 1.5 mL. In this context, it is important to highlight the importance of preoperative imaging exams to study the symmetries or asymmetries of this tissue for surgical planning.

    Each imaging exam has a contribution to make in the study of the anatomy of the ABC, and should be requested after the clinical exam according to the diagnostic hypothesis. CT is more accurate for hard tissues analysis, while USG and MRI provide more detail for soft tissues. Due to a greater detailing provided by images, CT and MRI can be useful for the study of face volumetric alterations that occur with aging[5] and the identification of pathologies in the hard or soft tissues of the maxillofacial region, such as masseter hypertrophy and condylar hyperplasias, as was suspected in the first and second reported cases, respectively.

    Jugal lipectomy also presents applications other than those described in the three clinical cases[10]. Bansal et al.[11] (2015) evaluated the viability of ABC as interposition material after arthroplasty and concluded that the volume of 1.1 mL of fat is efficient and stable as a barrier for preventing temporomandibular ankylosis. Recently, the literature discusses the ability of ABC to be an important source of mesenchymal stem cells, promising to produce bone tissue, muscle, cartilage, and fat. However, such information is not yet accurate and further studies are needed[12,13].

    Correction of oral defects, including closure of buccosinusal fistulae with ABC pedicled graft, is the most common indication found in the literature for jugal lipectomy[14]. The success of this grafting can be attributed to the rich vascularization of adipose tissue, an important condition for the long healing period[15]. However, even when a non-pedicled graft was used, as reported in the third clinical case, there was excellent tissue stability, and local vascularization was also provided by the palatal flap. Satisfactory results were also found in free grafts for treatment of patients with cleft lip and palate in the anterior region of maxilla[16].

    Three surgical accesses for jugal lipectomy are described in the literature: (1) 1 cm below the opening of parotid duct (Matarasso method), (2) behind the parotid papilla (Stuzin method), and (3) incision superior to the gingivobuccal sulcus[17]. In the first and second reported cases, the Matarasso method was used to provide wide and direct access to the buccal space, allowing the removal of a larger volume of ABC and its buccal extension, directly related to the contour of the cheek. In the third clinical case, jugal lipectomy did not present an aesthetic indication. Therefore, the gingivobuccal access was chosen since the aesthetic repercussion is almost insignificant. Upon performing an intraoral approach carefully to not pull the ABC and resecting only that which easily protrudes with gentle pressure, complications of excision for lipodystrophy or a pseudo herniated buccal fat pad are rare. The most likely complication would be over resection.

    Although complications are infrequent[18], lesions in the parotid gland, vascular plexus (branches of facial artery, maxillary artery, and transverse artery of the face), and the buccal branch of facial nerve may occur[19]. While the parotid duct presents a more lateral path in relation to the ABC, the vessels and buccal branches have a more superficial path and can go through the ABC extension[20]. Lesions of these structures can cause dry mouth sensation, the formation of large bruises, and even facial paralysis. Treatments include surgical repair of the duct, drainage of bruises and linking of blood vessels, anastomosis or grafting of neural tissue, and may be associated with laser therapy and corticosteroids. There were no hospitalizations, accidents, or complications in the three cases presented, and the procedure was performed at the dental office under local anesthesia. Superselective microcatheter angiography and embolization has been shown to be an effective modality for prompt treatment of bleeding from traumatic facial injury and refractory epistaxis when local methods fail to achieve hemostasis[21]. Trismus, infection, asymmetries, or cheek depressions may also occur, resulting from inadequate and lopsided removal of adipose tissue.

    Despite these complications, it is important to highlight that jugal lipectomy is a simple technique with few variations, fast execution, and low morbidity. It is essential to know the ABC anatomy of each patient through clinical examination and complementary imaging exams.
