The Buccal Fat Pad for Closure of Oroantral Communication

Anatomical and Surgical Implications of the Usage of Bichat Fat Pad in Oroantral Communication, Maxillary, Palatal, and Related Surgeries-Narrative Review

The buccal fat pad, also called the Bichat's fat pad (BFP), is an encapsulated fat mass located in the cheek. This type of specialized fat mass can be used both as a pedicular or free graft in various surgeries and approaches. Due to its easy access from the oral cavity approach, it is commonly used for oroantral and palatal fistula closure. The knowledge of its anatomy and surrounding tissues plays a role in its mobilization and suturing onto the desired defect in the palatal or maxillary region. The BFP is mostly associated with the primary approach used for a fistula or bone surgery. Alternatively, the procedure can be performed with a single approach incision, which does not compromise the appearance or the function of the operating or adjacent areas. The most important inclusion criteria for BFP usage and surgical limitations are highlighted. The BFP is used for multiple purposes in reconstructive and oncology surgery and also has its use in esthetic and facial contouring procedures. The amount, volume, and shape of the BFP are mostly associated with the scope of their usage. The aim of the following narrative review is to present the surgical and anatomical implications of fat pads in maxillary and palatal surgeries.

Surgical treatment of 61 consecutive patients with maxillary stage 3 medication-related osteonecrosis of the jaws using a pedicled buccal fat pad

PURPOSE

Buccal fat pad (BFP) is used for the closure of large oroantral defects caused by surgical removal of the necrotic bone in patients with medication-related osteonecrosis of the jaw (MRONJ). This study aimed to evaluate the use of BFP for the closure of maxillary sinus defects in stage 3 MRONJ patients.

METHODS

This study recruited 61patients with large oroantral defects caused by MRONJ, including 49 patients with cancer and 12 patients with osteoporosis. Lesions were evaluated clinically and radiographically.

RESULTS

Among the 61 patients, 51 (83.6%) healed uneventfully, and 5 patients (8.2%) had local dehiscence and exposed bone; these 56 patients (91.8%) all healed after first or second operation. The Eastern Cooperative Oncology Group Performance Status was associated with being non-cured and might be an indicator for the healing process. All patients experienced a significant increase in body weight postoperatively.

CONCLUSIONS

This study suggest that block resection with removal of the necrotic bone combined with radical sinusotomy and closure of the defect with BFP is a reliable method to cure MRONJ lesions with a high success rate, and successful operation and prosthetic rehabilitation may improve body weight and the quality of life. The study was approved by the appropriate ethical approval for the Copenhagen ONJ Cohort (protocol no. H-6-2013-010) November 20, 2013.

Unilateral Sinus Disease: Not Just Odontogenic! - A Retrospective Study

INTRODUCTION

Unilateral sinus disease (USD), and especially unilateral maxillary sinusitis (UMS), is an increasingly common finding in the ear, nose, and throat and maxillofacial practice. The aim of this retrospective study was to describe the clinical features of a series of patients affected by USD and, in particular, UMS due to sinonasal anatomic anomalies and of odontogenic origin.

MATERIALS AND METHODS

A total of 292 patients affected by UMS were reviewed. Medical charts, radiological images, and surgical notes were all reviewed, particularly including data on UMS due to sinonasal anatomic anomalies and on UMS of odontogenic origin.

RESULTS

A total of 66 patients have been excluded due to a diagnosis of malignant disease or other benign-defined etiology. Forty-eight patients (21.2%) affected by UMS due to sinonasal anatomic anomalies, whereas 178 (78.8%) patients affected by an odontogenic sinusitis. All patients were surgically treated by functional endoscopic sinus surgery, often in combination with a maxillofacial approach.

DISCUSSION

UMS of odontogenic origin represented the greater group of USD. Computed tomography scans are always recommended to define UMS etiology (in particular excluding a malignant origin) and also to plan the most adequate surgical treatment.
