PURPOSE
Before implant surgery, a preoperative radiological evaluation is recommended for recognizing maxillary inflammatory conditions. In order to avoid a failure of the dental procedure and prevent medical-legal consequences, it is necessary to treat patients suffering of maxillary sinus pathologies. The classification proposed in our study aims to standardize the reference values for mucosal thickening and to verify their association with the odontogenic or disventilatory causes of sinus pathology.
METHODS
The maximum mucosal thickness was measured at the level of the maxillary sinus floor: mucosal thickness was present when greater than 1 mm and was classified according to its extension within the sinus cavity.
RESULTS
Imaging data of 270 adult patients were included, performed for dental diagnosis and treatment planning, and they were divided into four main classes: Class I (85 pt.), mucosal thickness lesser than 2 mm, not pathological. Class II A (52 pt.), mucosal thickness between 2 and 5 mm, localized to the maxillary sinus floor: it is still considered non-pathological, and a "wait-and-see" approach is recommended. Class II B (46 pt.), mucosal thickness greater than 5 mm but localized at sinus floor: pathological mucosa with odontogenic etiology, requiring dental treatment. Class III A (39 pt.), mucosa thicker than 5 mm and concentric, most likely due to sinus ventilation disfunction: it requires maxillary antrostomy. Class III B (30 pt.), sinonasal manifestations such as nasal polyposis, retention cysts, mucocele, dental foreign body: pathological mucosa to be treated with ESS. Class IV (12 pt.), oroantral fistula: nasal endoscopic or oral approach.
CONCLUSIONS
Our classification intends to suggest the better therapeutic option, in case of sinus pathology, according to the entity and pathogenesis of the mucosal thickening, in order to reduce complication and failure rate of dental surgery.

Review
Maxillary implants are inserted in the upward direction, meaning that they oppose gravity, and achieving stable support is difficult if the alveolar bone facing the maxillary sinus is thin. Correspondingly, several sinus-lifting procedures conducted with or without bone graft materials have been used to place implants in the posterior area of the maxilla. Even with these procedures available, it has been reported that in about 5% of cases, complications occurred after implantation, including acute and chronic sinusitis, penetration of the sinus by the implant, implant dislocation, oroantral fistula formation, infection, bone graft dislocation, foreign-body reaction, Schneiderian membrane perforation, and ostium plugging by a dislodged bone graft. This review summarizes common maxillary sinus pathologies related to implants and suggests an appropriate management plan for patients requiring dental implantation.

Odontogenic sinusitis is a frequent disease of the maxillary sinus, resulting from a dental inflammatory condition or a foreign body migrated in the sinus cavity. We performed a clinical retrospective study aimed to review the two surgical endoscopic approaches for odontogenic maxillary sinusitis middle and inferior meatotomy, in terms of realistic indications, efficacy, outcomes, and possible complications. In our study, we included a number of 400 patients with odontogenic maxillary sinusitis divided into two groups, treated in our hospital over five years, from January 2019 to December 2023. The patients included in this research were over 18 years old, diagnosed with odontogenic maxillary sinusitis, and underwent either middle meatal antrostomy or inferior meatotomy. We examined the medical records of 400 patients. The vast majority of patients had a history of dental interventions, and the most affected tooth was the first maxillary molar. The symptoms at admission were typical for sinusitis: nasal obstruction, anterior or posterior rhinorrhea, hyposmia to anosmia, cacosmia, and pain or facial pressure. 80% of the patients in the study underwent middle meatal antrostomy, while 20% underwent inferior meatotomy. There were no significant differences between these two approaches in terms of efficacy, complication rates, recovery, or relapses. The complications that occurred after the surgical treatment were minor and with a very low frequency. The most reported were middle meatus synechiae and the persistence of the meatotomy ostium, with mucus recirculation (in patients with inferior meatotomy). Endoscopic surgical treatment of odontogenic maxillary sinusitis can be done as middle or inferior meatotomy, each having specific indications. The maxillary antrostomy is preferred in the majority of cases, as it is a procedure in which the natural ostium of the maxillary sinus is enlarged, thereby maintaining the natural drainage pathway of the sinus. However, the inferior meatotomy is preferred in the case of foreign bodies or maxillary sinus retention cysts localized at the level of the sinus floor or in the alveolar or lateral recesses, or as part of a combined approach (inferior and middle meatotomy), when the ablation of a "fungus ball" is required.

Review
The maxillary sinus is a structure at the border of specialties: otorhinolaryngology and maxillofacial surgery. Due to this fact, regarding etiology, it can be affected by both the rhinogenic and odontogenic path and can impose diagnostic difficulties. The etiopathogenic mechanisms that can affect the Schneiderian membrane are mainly inflammatory, iatrogenic, traumatic, and tumorous in nature. From a microbiological point of view, the bacteriology is polymorphic, including both aerobic and anaerobic species in acute OS, the predominating species in acute OS being aerobic, and in chronic anaerobic germs. The role of fungi in the determination of this pathology and in the production of the biofilm that leads to resistance to antibiotic treatment is also discussed. The present paper aims to present the etiopathogenesis, bacteriology, clinical manifestations, as well as treatment of odontogenic sinusitis (OS) from an updated perspective through reviewing the literature. If unilateral maxillary sinusitis is usually due to odontogenic causes, this does not clinically exclude the possibility of strictly rhinogenic causes in the occurrence of sinusitis. This underlines the important role of complex oral and rhinological clinical examination as well as the role of preclinical examinations in specifying the certainty diagnosis. Simple radiography, orthopantomography, CT, and CBCT are compared in terms of diagnostic accuracy. The treatment of OS is complex, involving medication, dental, and surgical measures. The value of endoscopic surgery is emphasized, comparing its advantages over the classic Caldwell-Luc technique.

Meta-Analysis Review
Currently, two separate Cochrane reviews, ‘’ and ‘’ describe the effect of antibiotics for acute rhinosinusitis. Although both Cochrane reviews study the same condition, they look at different populations (patients in which the diagnosis was based on clinical signs and symptoms and patients in which the diagnosis was confirmed by imaging). Because of this, the conclusions are different in these Cochrane reviews. This was confusing for clinicians who needed to read both Cochrane reviews to know which conclusions are most applicable to their patients. This review is being withdrawn and will be incorporated into the updated publication of ‘’. This ‘merged’ review will still maintain the relevant distinction between the two populations. However, information on the effectiveness of antibiotics for rhinosinusitis will be published in the ‘merged’ Cochrane review. We will omit the comparison between antibiotics (as published in this Cochrane review) because the choice for certain antibiotics and/or doses differs according to the local antibiotic resistance patterns and therefore this comparison is less relevant. The editorial group responsible for this previously published document have withdrawn it from publication.

BACKGROUND
Midfacial fractures frequently involve the maxillary sinus, leading to maxillary sinus pathology. We aimed to examine the incidence and contributing factors of maxillary sinus pathology in patients who underwent open reduction and internal fixation (ORIF) for midfacial fractures.
METHODS
A retrospective analysis was conducted on patients who underwent ORIF for midfacial fractures at our department over the past 10 years. The incidence of maxillary sinus pathology was identified clinically and/or by computed tomography findings. Factors that significantly influenced the groups with and without maxillary sinus pathology were examined.
RESULTS
The incidence of maxillary sinus pathology in patients who underwent ORIF for midfacial fractures was found to be 11.27%, with sinusitis being the most common pathology. Maxillary sinus pathology was significantly associated with the presence of a blowout fracture involving both the medial and the inferior orbital walls. Factors such as sex, age, diabetes mellitus, hypertension, smoking, inflammatory disease, follow-up period, use of absorbable plates, and use of titanium plates did not have a significant impact on the development of maxillary sinus pathology.
CONCLUSION
The incidence of maxillary sinus pathology in patients who underwent ORIF for midfacial fractures was relatively low, and in most cases, it resolved without the need for specific treatment. Consequently, there may not be a significant need for concern regarding postoperative maxillary sinus pathology.

INTRODUCTION
Upper respiratory tract infections and sinusitis are more prevalent in children than in adults. Unilateral sinusitis is not uncommon disease. Our aim was to analyze the disease characteristics in children with unilateral sinusitis and compare them with those of adults.
MATERIALS AND METHODS
This study included 124 patients with unilateral chronic sinusitis divided according to age into two groups: pediatric group ≤18 years (66 cases) and adult group >18 years (58 cases). The groups were compared in terms of demographic data, side, clinical manifestations and radiological findings.
RESULTS
In pediatric patients, the most common inflammatory pathology was antrochoanal polyps, followed by allergic fungal sinusitis. On the other hand, chronic sinusitis without nasal polyps is the most common in adults, followed by antrochoanal polyps. The mean duration of clinical manifestations before diagnosis in pediatric patients was significantly shorter than that in adults (P=0.001). The most common symptoms in both pediatric and adult patients were anterior nasal discharge and nasal obstruction. Proptosis was significantly higher in pediatric group than in adult group (P=0.015). On computed tomography (CT), the most commonly affected sinus in both pediatric and adult patients was the maxillary sinus followed by the anterior ethmoid sinus. Bone expansion, erosion and involvement of adjacent structures were significantly higher in pediatric patients (P=0.028, 0.027 respectively).
CONCLUSION
Pediatric patients have a high incidence of antrochoanal polyps and allergic fungal sinusitis as unilateral inflammatory lesions. These lesions require surgical management. Inflammatory paranasal sinus lesions in pediatric patients have a shorter duration of clinical manifestations and a higher incidence of bone erosion and involvement of adjacent structures; therefore, early diagnosis and management prevent complications.

OBJECTIVE
Odontogenic maxillary sinusitis (OMS) is a well-recognized disease in otolaryngology and oral and maxillofacial surgery. It is diagnosed comprehensively based on the presence of dental disease and radiographic evaluation. Although the disease involves a combination of dental and otorhinolaryngological features, appropriate criteria have not been well established for prioritizing dental procedures in the initial treatment of OMS. We investigated whether computed tomography (CT) score, including the Lund-Mackay score, can help prioritize tooth extraction as the initial treatment for OMS.
METHODS
We also investigated the radiographic features of 32 patients with OMS treated by tooth extraction alone. Both pre-and post-extraction CT images of OMS cases were evaluated.
RESULTS
Lund-Mackay scores before tooth extraction were significantly lower in postoperatively healed patients than in non-healed patients. Furthermore, CT scores of the anterior and posterior ethmoid sinuses and frontal sinuses, obtained before tooth extraction, were significantly lower in postoperatively healed patients than in non-healed patients.
CONCLUSIONS
Collectively, low Lund-Mackay and CT scores of the ethmoid and frontal sinuses are significantly associated with healing of OMS treated by tooth extraction alone. The sinus CT score can help identify a treatment strategy for OMS.

Odontogenic sinusitis is a well-known, but under-studied bacterial infection of the maxillary sinus that can extend to other sinuses, the orbit, or even the endocranium. We performed an observational retrospective study on the patients with odontogenic sinusitis treated in our hospital over a five-year period. We included patients over 18 years old diagnosed with odontogenic sinusitis and ocular complications and we excluded patients with ocular complications nonrelated to dental-originated sinusitis or patients with odontogenic sinusitis without orbital-ocular complications. We examined the charts of 46 patients. From the total number of patients with oculo-orbital complications generated by odontogenic sinusitis, only 7 were women. The mean age was 33,7 with a standard deviation of 15,7 years. The oculo-orbital complications were assessed according to the Chandler classification. The most frequent orbital complication was preseptal cellulitis followed by orbital cellulitis. All the patients were treated with antibiotic covering both anaerobic and aerobic bacteria and 40 of the patients in our study received surgical treatment. The outcomes were favorable for all the patients in our study with clinical resolution. The oculo-orbital complications of odontogenic sinusitis are severe because they can result in vision loss or other ocular sequelae. The bacteriological features of this sinusitis explain the special characteristics of this infection and can facilitate the extent of the infection to the orbit. Prompt intervention with antibiotics covering anaerobic and aerobic bacteria and surgery addressed to the affected sinus/ sinuses, the dental disease and the orbital pathology ensures a big success rate in the therapy of these complications.

Although the incidence of postoperative acute and chronic rhinosinusitis in patients undergoing a sinus lift procedure is relatively high, a paucity of rhinology literature examines the management of and outcomes for this patient population. The objective of this study was to review the management and postoperative care of sinonasal complications and identify possible risk factors that should be considered prior to and following sinus augmentation. We identified sequential patients who had undergone a sinus lift procedure and were referred to the senior author (AK) at a tertiary rhinology practice for intractable sinonasal complications and reviewed their charts for demographic data, history of illness including prereferral treatment, examination findings, imaging results, treatment modalities, and culture results. Nine patients were initially treated medically without improvement and subsequently underwent endoscopic sinus surgery. The sinus lift graft material remained intact in 7 patients. Two patients had extrusion of the graft material into the facial soft tissues, resulting in facial cellulitis requiring graft removal and debridement. Seven of the 9 patients had predisposing factors that could have prompted referral to an otolaryngologist for optimization prior to sinus lifting. The mean follow-up was 10 months, and all patients had full resolution of symptoms. Acute and chronic rhinosinusitis is a complication of the sinus lift procedure and is more commonly seen in patients with preexisting sinus disease, anatomic sinonasal obstruction, and Schneiderian membrane perforation. Preoperative evaluation by an otolaryngologist may improve outcomes in patients at risk of sinonasal complications from sinus lift surgery.
