| Abstract|| |
Rehabilitation of the long-standing edentulous posterior maxilla with dental implant poses a unique challenge. This is due to mainly two reasons – pneumatization of the maxillary sinus and atrophy of the alveolar bone. The challenge is intensified when the native bone is around 2–3 mm. This requires vertical bone augmentation in the form of direct sinus lift/lateral wall sinus lift procedure. The most common complication associated with this procedure is the sinus membrane perforation resulting in unfavorable stabilization of the graft and associated bone regeneration. Simultaneous implant placement becomes all the more difficult in such situations. As a result, of which implant placement has to be deferred resulting in extended treatment duration and multiple surgical appointments. The present case report represents two such sinus membrane perforation repair cases associated with lateral wall osteotomy approach for sinus augmentation with simultaneous implant placement in the posterior maxilla.

| Introduction|| |
Maxillary sinus augmentation procedures are usually done by the crestal or lateral approach, which are the more predictable treatment modalities for placing the implant in the atrophic maxillary posterior area. Although associated with high risk of intra- or postsurgical complications, sinus elevation surgery is considered one of the most predictable bone augmentation procedures. According to evidence-based literature review, there is high level of predictability in the outcome of lateral wall sinus elevation surgery.,,
Intraoperative complications are primarily the result of surgical difficulties associated with the presence of complex anatomic limitations such as thin membrane, septa, and thick or convex lateral walls. Various complications associated with the procedures include Schneiderian membrane perforation, intraoperative bleeding, perforations of the buccal flap, and injury to the infraorbital nerve.
The most common intraoperative complication in sinus elevation surgery is the perforation of the Schneiderian membrane, which ranges between 10% and 55% when rotary window preparation is used. Perforation may result in decrease in bone formation or infection in maxillary sinus thus resulting in subsequent implant failure.,
Various techniques have been used in literature for repair of Schneiderain membrane perforation that increased the survival rate of implants.,, The most common perforation repair procedures include direct repair of Schneriderain membrane by suturing or indirect repair by use of resorbable-guided tissue regeneration membrane.,,,
Based on the size of the perforations, Hernández-Alfaro et al. [Table 1]:
- Less than 5 mm
- Between 5 and 10 mm
- More than 10 mm.
Treatment options in cases of sinus membrane perforations, depending on the extent
This article shows cases management of two such cases where sinus membrane perforation during lateral sinus lift procedure has occurred. In many cases where the procedure is abandoned usually, a successful attempt was made to simultaneously repair the perforation as well as place the implant.
| Case Reports|| |
A 62-year-old female patient reported to the department of periodontology with the chief complaint of missing teeth within the upper left region of the jaw.
There was no significant relevant medical history. On intraoral examination, missing teeth 16, 26, 27, 36 were revealed. Investigations including orthopantomogram (OPG), cone-beam computed tomography (CBCT), complete blood count (CBC), bleeding time (BT), and clotting time (CT) were carried out. According to CBCT, the residual bone measurement for the prospective implant site was approximately 3.2 mm [Figure 1]a. As a result of which direct sinus lift procedure was opted for.

The surgical site with respect 26 and 27 was administered with 2% lignocaine hydrochloride (1:200,000 adrenaline). Full-thickness flap was reflected after giving mid-crestal incision with 26 and 27 region and vertical releasing incisions on the mesial line angle of 25 [Figure 1]b. Thinning of the lateral window to gain access for the sinus membrane elevation was done with a round bur [Figure 1]c. During the sinus elevation, sinus membrane perforation of approximately 6–7 mm occurred [Figure 1]d. Perforation of sinus membrane was managed by 6-0 resorbable chromic gut suture [Figure 1]e followed by placement of collagen membrane, i.e., periocol [Figure 1]f.
Following perforation repair and sinus membrane elevation, osteotomy site preparation and implant placement (implant size – TS 4.5 mm × 10 mm Osstem) was done with respect to 26 [Figure 1]g and [Figure 1]h.
The sinus space was packed with demineralized freeze-dried bone allograft (DFDBA) + FDBA + hydroxyapatite and collagen membrane (Periocol) following the implant placement. 3-0 reverse cutting direct loop sutures were placed.
The patient was prescribed tablet amoxicillin and clavulanic acid 625 mg 2/day for 5 days, tablet diclofenac 50 mg 2/day for 3 days, and tablet cetirizine 5 mg 2/5 days. Chlorhexidine gluconate 0.2% mouthrinse twice daily for 2 weeks was prescribed to the patient.
The second-stage implant surgery was done with scalpel, and healing abutment was placed. A screwed-retained metal-ceramic prosthesis was delivered [Figure 1]i and [Figure 1]j.
A 37-year-old male patients reported to the department of periodontology with the chief complained of missing teeth within the upper right region.
There was no significant relevant medical history. Intraoral examination revealed missing tooth 16 Investigations, including OPG, CBCT, CBC, BT, and CT, were carried out. According to CBCT, the residual bone measurement for the prospective implant site was approximately [Figure 2]a as a result of which direct sinus lift procedure was opted for.

The surgical site with respect to 16 was administered with 2% lignocaine hydrochloride (1:200,000 adrenaline). Full-thickness flap was reflected after giving mid-crestal incision with 16 and 17 region and vertical releasing incisions on the mesial line angle of 15 [Figure 2]b. Thinning of the lateral window to gain access for the sinus membrane elevation lead to approximately 2-3 mm of sinus membrane perforation [Figure 2]c. Perforation of the sinus membrane was managed by collagen membrane, i.e., periocol [Figure 2]d. Following perforation repair and sinus membrane elevation, osteotomy site preparation and implant placement (implant size – 4.5 mm × 10 mm Dentium) was done with respect to 16 [Figure 2]e and [Figure 2]f.
The sinus space was partially packed with DFDBA + FDBA + platelet-rich fibrin following the implant placement. The bony window was obliterated with Chorion membrane. 3-0 reverse cutting direct loop sutures were placed.
The patient was prescribed amoxicillin and clavulanic acid 625 mg 2 tablets for 5 days, diclofenac 50 mg 2 tablets for 3 days, and cetirizine 5 mg 2 tablets for 5 days. Chlorhexidine gluconate 0.2% mouthrinse twice daily for 2 weeks was prescribed to the patient.
The second-stage implant surgery was done with scalpel and healing abutment was placed. A screwed retained metal-ceramic prosthesis was delivered [Figure 2]g.
| Discussion|| |
Maxillary sinus augmentation is commonly done to increase bone dimension for placement of dental implants in the posterior maxilla. The most important factor during the sinus augmentation procedure is to maintain the integrity of the Schneiderian membrane so that once lifted, it can become the recipient site for the bone graft and stabilizes the graft during the healing period. Sinus membrane perforation is the most common complication of sinus elevation surgery (prevalence – 10%–55%) which has an adverse impact on graft remodeling.
For repair of small sinus membrane perforations (small membrane perforations <5 mm), numerous techniques can be employed such as circumelevation technique, Loma Linda Pouch technique, tissue fibrin glue technique, suturing, or by covering the sinus membrane perforation with a resorbable barrier membrane. In Case 2, the collagen membrane was used for the sinus membrane perforation repair.
For repair of larger perforation (>5 mm) various techniques advocated are – lamellar bone plates, resorbable barrier membranes, and suturing alone or suturing in combination with fibrin glue. In the present Case 1, Schneiderian membrane perforation was repaired by using a resorbable chromic gut suture and grafting.
The results of sinus augmentation techniques are made more pronounced and predictable by the use of different graft materials such as autogenous, allogenous, xenograft, and alloplastic materials.
Sinus elevation surgery with simultaneous implant placement requires ≥4 mm of native bone for primary stability. In the current case report, implants were placed simultaneously with sinus augmentation procedure in spite of native bone <4 mm (Case 2 = 3.6 mm, Case 1 = 3.2 mm) after managing the perforation of the sinus membrane. This makes it a novel procedure because mostly the implants in such cases of larger perforation are placed with delayed approach. This case report manages the simultaneous implant placement with perforation repair. Postoperative radiograph showed appreciable bone fill and osseointegration at the implant site.
The patient was rehabilitated with a functional prosthesis despite the above-mentioned complication. The advantage of the simultaneous implant placement encompasses reduction in various aspects such as surgical procedures, treatment time, morbidity, financial expense, patient anxiety, and the tenting effect of the implant on the repaired sinus membrane acting as a space maintainer.
| Conclusion|| |
While implants have become the treatment of choice for replacement of missing teeth, tooth loss following periodontal or other complications result in a reduced bone support. Intraoperative complications may lead to postoperative complications if not addressed in time. These cases suggest that surgical complications did not significantly influence implant survival as consultation was sought immediately and preparations for addressing the complications were made beforehand. The case with membrane tears had comparable results as the noncomplicated cases, hence proving that timely intervention gives predictable results without significantly increasing the treatment time or number of surgical procedure.
