Review
A maxillary sinus lift procedure is indicated if a dental implant needs to be placed in the posterior maxilla with limited bone available to accommodate a dental implant. Both open and closed sinus lifting procedures are reliable approaches for increasing the bone volume needed to support proper implant positioning. However, these methods can lead to several complications. In addition to the general complications commonly linked to oral surgery, such as swelling or hematoma, the primary complication in open sinus lifting is typically the perforation of the Schneiderian membrane during osteotomy. Detailed and extensive presurgical evaluation is crucial to minimize such complications. The objective of this study was to delineate contemporary trends in sinus lift surgery, with a specific emphasis on different techniques of sinus lift procedure, anatomical and surgical factors, presurgical evaluation, bone grafting, and the practical implications of these factors in implant dentistry cases involving a deficient posterior maxilla. In conclusion, while both osteotome and lateral window techniques can assist clinicians in addressing the complexities of implant placement in a deficient posterior maxilla, bone height before implantation remains a critical factor in determining the success and longevity of implants.

Review
Maxillary Sinus Augmentation Using Autologous Platelet Concentrates (Platelet-Rich Plasma, Platelet-Rich Fibrin, and Concentrated Growth Factor) Combined with Bone Graft: A Systematic Review.
BACKGROUND
The current review aims to provide an overview of the most recent research on the potentials of concentrated growth factors used in the maxillary sinus lift technique.
MATERIALS AND METHODS
"PRP", "PRF", "L-PRF", "CGF", "oral surgery", "sticky bone", "sinus lift" were the search terms utilized in the databases Scopus, Web of Science, and Pubmed, with the Boolean operator "AND" and "OR".
RESULTS
Of these 1534 studies, 22 publications were included for this review.
DISCUSSION
The autologous growth factors released from platelet concentrates can help to promote bone remodeling and cell proliferation, and the application of platelet concentrates appears to reduce the amount of autologous bone required during regenerative surgery. Many authors agree that growth factors considerably enhance early vascularization in bone grafts and have a significantly positive pro-angiogenic influence in vivo when combined with alloplastic and xenogeneic materials, reducing inflammation and postoperative pain and stimulating the regeneration of injured tissues and accelerating their healing.
CONCLUSIONS
Even if further studies are still needed, the use of autologous platelet concentrates can improve clinical results where a large elevation of the sinus is needed by improving bone height, thickness and vascularization of surgical sites, and post-operative healing.

INDICATIONS CORRIDOR AND LIMITS OF EXPOSURE
The endoscopic endonasal transpterygoid approach (EETPA) provides direct access to the petrous apex, lateral clivus, inferior cavernous sinus compartment, jugular foramen, and infratemporal fossa. 1,2 In the coronal plane, it provides exposure far beyond a traditional sphenoidotomy.
ANATOMIC ESSENTIALS NEED FOR PREOPERATIVE PLANNING AND ASSESSMENT
The pterygoid process of the sphenoid bone forms the junction between the body and greater sphenoid wing before bifurcating because it descends into medial and lateral plates. The key to this exposure lies in the region's bony foramina: the palatovaginal canal, vidian canal, and foramen rotundum. 3.
ESSENTIALS STEPS OF THE PROCEDURE
After performing a maxillary antrostomy, stepwise exposure of these foramina leads to the pterygopalatine fossa. The sphenopalatine artery is cauterized as it becomes the posterior septal artery at the sphenopalatine foramen, and the maxillary sinus' posterior wall is opened to expose the pterygopalatine fossa. After mobilizing and retracting the contents of the pterygopalatine fossa, the pterygoid process is removed, improving access in the coronal plane. 4.
PITFALLS/AVOIDANCE OF COMPLICATIONS
Vidian neurectomy causes decreased or absent lacrimation. Injury to the maxillary nerve or its branches results in facial, palatal, or odontogenic anesthesia or neuralgia. In addition, the EEPTA precludes the ability to raise an ipsilateral nasal septal flap, making it crucial to plan reconstruction preoperatively. 4,5.
VARIANTS AND INDICATIONS FOR THEIR USE
There are 5 variants of the EEPTA: extended pterygopalatine fossa, lateral recess of the sphenoid sinus, petrous apex, infratemporal fossa and petrous carotid artery, and middle and posterior skull base. 5The patient consented to the procedure.Images in the video used with permission as follows: images at 0:33 and 1:15 reused from Bozkurt et al, 3 © Georg Thieme Verlag KG; image at 0:39 from Prosser et al, 5 © John Wiley and Sons; images at 0:54, 9:03, and 9:38 from Kasemsiri et al, 1 © John Wiley and Sons; images at 1:07 and 9:44 from Falcon et al, 2 © John Wiley and Sons; image at 1:15 from Sandu et al, 4 © Springer Nature.

Review
PURPOSE OF REVIEW
The purpose of this review is to summarize current evidence regarding the use of induction chemotherapy for a variety of histopathologies of sinonasal malignancy (SNMs) and to review the potential adverse effects of cytotoxic agents.
RECENT FINDINGS
Historically, patients with locally advanced SNMs have had relatively poor prognoses and high morbidity from treatment. The available retrospective data suggests that induction chemotherapy may improve outcomes for patients with sinonasal undifferentiated carcinoma (SNUC), neuroendocrine carcinoma, squamous cell carcinoma (SSCC), and esthesioneuroblastoma. For SNUC and SSCC, response or nonresponse to induction chemotherapy may prognosticate outcomes and for SNUC specifically, drive selection of definitive therapy. In chemosensitive pathologies, induction chemotherapy appears to improve organ preservation.
SUMMARY
Induction chemotherapy may improve functional and oncologic outcomes for patients with SNMs. Because of the rarity of these pathologies, the available data is primarily retrospective. Future randomized, prospective studies should be performed to further optimize and elucidate the role of induction chemotherapy for SNMs.

Review
Maxillary sinus floor augmentation using lateral window and crestal technique is considered as predictable methods to increase the residual bone height; however, this surgery is commonly complicated by Schneiderian membrane perforation, which is closely related to anatomical factors. This article aimed to assess anatomical factors on successful augmentation procedures. After review of the current evidence on sinus augmentation techniques, anatomical factors related to the stretching potential of Schneiderian membrane were assessed and a decision tree for the rational choice of surgical approaches was proposed. Schneiderian membrane perforation might occur when local tension exceeds its stretching potential, which is closely related to anatomical variations of the maxillary sinus. Choice of a surgical approach and clinical outcomes are influenced by the stretching potential of Schneiderian membrane. In addition to the residual bone height, clinicians should also consider the stretching potential affected by the membrane health condition, the contours of the maxillary sinus, and the presence of antral septa when evaluating the choice of surgical approaches and clinical outcomes.

Mucocele is a benign, expansile, and oppressive lesion, more common in the frontal and ethmoid sinus and less in the maxillary sinus. Sinus mucocele mainly causes cheek swelling pain and nasal obstruction. In some cases, the paranasal mucocele grows large enough to compress periorbital structures and lead to impaired vision. Generally, mucocele is full of simple mucus, but pathogens can be found if co-infected, which means a poor prognosis. Functional endoscopic sinus surgery is an effective treatment for this disease. Here, the authors report a case that a mucocele occurred in the maxillary sinus, and a fungal ball was also found during the operation, which is a result of Paecilomyces farinosus co-infection.

BACKGROUND
Maxillary sinus mucocele is a rare form of mucocele and are usually under diagnosed due to its vague symptomatic presentation. It is caused by obstruction of the natural ostium and accumulation of secretions inside the sinus cavities. It is a locally expansile lesion and symptoms are due to pressure on surrounding structures.
CASE PRESENTATION
A 45 -year- old female patient presented with swelling on the left side of the face for 6 months with left infra orbital pain. On examination the swelling was diffuse in the left side of cheek. CT scan showed a homogenous opacity completely filling the maxillary sinus with expansion of the walls which helped in diagnosing the condition. Endoscopic marsupialisation was done and the patient is under follow-up for more than a year with no recurrence.
CONCLUSION
Maxillary sinus mucocele is an epithelium lined sac filled with mucous secretions. They are expansile and can cause bony erosion of surrounding anatomical structures. It is mainly differentiated radiologically by the presence of air in the sinus cavity. CT scan shows homogenous opacity completely filling the antrum with no air shadow. The walls may be thickened or thinned out. Endoscopic marsupialisation of the mucocele gives excellent results with minimal recurrence. Maxillary mucocele being a rare benign cystic lesion is mostly under diagnosed. Hence, proper clinical examination and radiological evaluation help in early diagnosis. Appropriate surgical management gives a good success rate with nil recurrence.
