Prosthetic Rehabilitation of a Patient with Nose Defect

Prosthetic Rehabilitation of a Patient with Nose DefectCase ReportAuthors Satyabodh S Guttal, MDS,MFPT 1, Blessy Bangera, BDS,2 Adarsh Kudva,MDS,3 Basavaraj R Patil, MS, 4AbstractMidfacial defects are bulky defects that result from cancer treatment that rarely are corrected by surgical rebuildion alone they generally require a facial prosthetic device to restore function and appearance. Surgical reconstruction may be viable for few defects, which are done with different flaps. But for the total wasted resection, prosthetic option would be more feasible. Nasal cartilaginous anatomy is complex due to the varying contours. Therefore it may be difficult for the surgeon to reconstruct the entire trespass. This clinical report describes the replacement of a enormous midfacial nose defect with a dental implant retained emaciated prosthesis. The patient had adenocystic carcinoma of the mesial maxillary wall extending to the nose.IntroductionThe face being the most noticeable part o f the body when disfigured may lead to an impaired social manner stemming from esthetic problems. 1, 2 Among facial defects, hard up defects produce severe cosmetic impairment. . Rehabilitation of such defects subsequent to surgery is done in a incidental manner, which includes a surgical, provisional, and classic prosthesis. 3 Prosthesis helps restore the patients self-esteem and confidence, hence affecting the patients and their life style. 4-6Adenoid cystic carcinoma (ACC) is a rare malignant perineural neoplasm of the major and minor salivary glands, accounting for 2% of all head and neck malignancies and approximately 10% of all salivary gland neoplasms. 60% to 70% of ACCs arise in the minor salivary glands, which may be local anaestheticized in the palate, paranasal sinuses and nose, although they may also occur in the parotid or submandibular glands.7In the past, nasal prostheses were held in position with strings or straps fastened behind the head,8 intranasal or intraor al extensions,9,10 and gold strings or leaves.11-13 Spectacle frames have been true for securing nasal prostheses.14,15 Today, with the development of biomaterials, prosthetic substitutes are secured with readily available adhesives that are effortlessly applied 16 however, the effectiveness of adhesives is questionable considering presence of mobile tissues in the defect, nasal secretions, and moist air associated with respiration.17 These factors would compromise the adhesiveness. The concept of osseointegration 18 has enabled a more reliable mode of retaining nasal prostheses. 19 This clinical report describes the rehabilitation of a large midfacial defect using an implant retained nasal prosthesis.Clinical ReportA 63-year-old female patient who reported to the B.R Patil Cancer hospital, Navanagar, Dharwad was diagnosed with adenocystic carcinoma of the medial maxillary wall. Patient had no medical co-morbidity. Patient gave history of nasal obstruction due to nasal mass on lef t side of the nostril for which medial maxillectomy was done via endoscopic approach in the year 1993. Then in 2012 she reported back with the complaint of nodular swelling over nasal dorsum with tearing and nasal obstruction with no orbital symptoms. Intra-orally patient had destruction of palate on the left side crossing midline. Upon further investigation, biopsy revealed adenocystic carcinoma of the nose and left maxilla with no involvement of orbit or anterior skull base (Fig 1). Two cycles of chemotherapy with cisplatin, 5 flurouracil and paclitaxel according to body surface area was given.The defect resulting after excision had to be covered at the earliest. Hence, prior to surgical intervention, prosthetic consultation was suggested to the patient who was thus referred to our Department of Maxillofacial Prosthodontics. Since an immediate definitive prosthesis was not feasible, the patient was suggested for temporary rehabilitation with an interim silicone polymer nasal pros thesis with an attached eyeglass frame. However, since the patient expressed her displeasure towards spectacles for lifelong usage, she was given the option of implant-retained definitive silicone nose prosthesis. The patient agreed for the same. An orthopantomograph and computerized tomography scan were made as a part of the investigation to evaluate the bone height for implant placement.Left total maxillectomy with palatal resection across midline and total nasal resection done via weber ferguson incision, left modified radical neck dissection type three via macfee incision was made. The glabellar bone was evaluated on the operation table and upon conclusion that adequate bone was available a bingle implant of 4.2 diameter x 6.5mm length, (Toureg S Adin implants, Nazareth, Israel) was dictated (Fig 2). The advantage of placing the implant on the operation table was that the patient would be chthonian general anesthesia, and the psychological trauma of undergoing another surgic al procedure was avoided. succeeding(a) a healing period of 3 months the dissipate tray impression posts were placed and the final impression was made. The abutment was placed on the implant and a custom made acrylic sleeve was fabricated for the abutment (Fig 3). A wax sculpted nose on the master slog was made to adapt to the margins of the healing wound. On either sides of the acrylic resin sleeve, two neodymium-iron-boron magnets, 5mm diameter x 1.2mm thick (Magnatech Mumbai, India) were embedded into extensions made out of autopolymerising resin. The expression hence resembled a winged sleeve which was cemented on to the abutment using zinc-phosphate cement (Harvard Dental, Hoppegarten,Germany) (Fig 4). An acrylic resin index was fabricated over this structure which would harbor the respective(prenominal) magnetic keepers. The acrylic index was placed at its position over the magnets and was picked up by the wax nose that was placed on it using a drop of cyanoacrylate. The re sulting wax nose thus incorporated an acrylic index with the magnetic keepers. This wax nose was carefully invested and the packing procedure using silicone and acrylic resin border framework, intrinsic coloring was carried out as mentioned for the interim above. Extrinsic coloring and pigmentation was done and patient was happy with the esthetic results. digital weighing scale revealed that the definitive nasal prosthesis weighed around 12.2gms. The retentive force offered by the two neodymium-iron-boron magnets (Magnatech Mumbai, India) was found to be 7.2N. The prosthesis was delivered to the patient (Fig 56). Following this, home-care instructions were given. In the subjective evaluation, the patient was very happy with the esthetics outcome of the prosthesis and expressed her great pleasure towards her ability to swallow liquids. The ryles vacuum tube continued to remain in place considering the general health condition of the patient and the need to feed semi solid food and p rotein supplements. The prosthesis was inflame in weight and could be comfortably placed in position as it was self-aligning due to the use of magnets. Patient, who is now on regular periodic recap ie, recalling at every 3 month period, is found to be doing well.DiscussionNasal reconstruction modalities comprises of primary closure, healing by secondary intention, skin grafts and local flaps and regional flaps. Small surgical defects can be treated well with different types of local flaps. The forehead flap is the better option for the large nasal defects. 20 The complex anatomical configuration may cause difficulty in surgical rehabilitation. In such cases, prosthetic closure is inevitable and hence usually the treatment of choice. 21,22 The breakthrough for rehabilitation of facial defects with implant-retained prostheses came with the development of the modern silicones and bone anchorage.The limitations of the prosthesis were explained to the patient prior to the treatment, t hat fact that the prosthesis would grow esthetics but would contribute less to the functions like speech and masticatory habits. Hence, the patient had no psychological set back on the prognosis of the treatment. In addition, there was a major set-back in terms of achieving outstanding esthetical and functional outcome due to the fact that all the work was carried out under technical constraints. This included a lack of time, chair-side patient availability, and ideal light conditions which, to an extent precluded optimal color blending.The main objective of treating this case was to close the open defect, to prevent the further spread of infection in the soft tissues exposed to the environment. The use of a magnetic assembly has eliminated the need for use of spectacle retention as per the patients request. The patient indicated that the nasal prosthesis reduced self-consciousness and was comfortable to wear without any type of irritation to the surrounding skin. The patient was satisfy with her appearance and no longer found the need to wrap a cloth around her face.ReferencesGuttal SS, Patil NP, Thakur S, Kumar MV, Kulkarni S.
