Surgical Management of Benign Tumors of the Parotid Gland: Extracapsular Dissection Versus Superficial Parotidectomy—Our Experience in 232 Cases

PURPOSE The purpose of this study was to retrospectively analyze all cases of benign parotid tumors treated at our institution from 2002 to 2009. MATERIALS AND METHODS We carried out a retrospective review of 232 patients with benign primary parotid tumors. Extracapsular dissection or superficial parotidectomy was performed. Clinical and histopathologic data were analyzed, and management was described. The statistical difference between the 2 techniques as concerns evaluated recurrence rate and complications was measured with the log-rank (Cox-Mantel) test. The chosen level of statistical significance was P < .05. RESULTS A total of 232 patients were enrolled, 107 women and 125 men, whose mean age was 53.2 ± 11.3 years. Extracapsular dissection was performed in 176 cases (76%) (mean age, 52.82 ± 11.55 years), and superficial parotidectomy was performed in 56 cases (24%) (mean age, 54.59 ± 10.56 years). The mean lesion size was 1.89 ± 0.52 cm for extracapsular dissection and 3.49 ± 0.43 cm for superficial parotidectomy (P < .001). Mean follow-up was 52.6 ± 4.5 months for the group of patients treated with superficial parotidectomy and 46 ± 5.2 months for the group treated with extracapsular dissection. No significant differences as concerns capsular rupture and recurrence were observed after extracapsular dissection and superficial parotidectomy (3.4% vs 1.8% [P = .1] and 4.5% vs 3.6% [P = .1], respectively). Transient facial nerve injury, facial paralysis, and Frey syndrome were significantly more frequent after superficial parotidectomy than after extracapsular dissection (26.8% vs 3.9% [P = .001], 8.9% vs 0% [P < .001], and 5.3% vs 0% [P < .001], respectively). CONCLUSIONS Extracapsular dissection showed similar effectiveness and fewer side effects than superficial parotidectomy and could be considered as the treatment of choice for tumors located in the superficial portion of the parotid gland.

Reconstruction of small orbital floor fractures with resorbable collagen membranes.

AbstractOrbital floor fractures are the most common facial fractures. The goals of orbital floor fracture repair are to free incarcerated or prolapsed orbital tissue from the fracture defect and to span the defect with an implant to restore the correct anatomy of the orbital floor and the pretrauma orbital volume. No consensus exists on the choice of implants to be used for orbital floor reconstruction, and several implant materials are available.Our study intended to evaluate, for the first time, the effectiveness and complications related to the use of a resorbable collagen membrane in the reconstruction of small pure blow-out fractures. From October 2008 to November 2010, 23 patients who underwent reconstruction of the orbital floor using a resorbable collagen membrane following fracture were included in this study. At the 6-month follow-up, only 2 patients (9%) reported postoperative complications secondary to the operative procedure (surgical approach, orbital floor dissection), but these were not directly related to the use of the membrane. In 12 cases, a computed tomography scan revealed new bone formation beneath the membrane.On the basis of this data, we believe that the use of a resorbable collagen membrane is a safe and effective alternative for reconstruction of small (<3 cm2) pure orbital floor fractures.

Microvascular free-flap transfer for head and neck reconstruction in elderly patients

BackgroundWith the increase in life expectancy, the incidence of head and neck cancer has grown in the elderly population. Free tissue transfer has become the first choice, among all the reconstructive techniques, in these cases. The safety and success of micro vascular transfer have been well documented in the general population, but its positive results achieved in elderly patients have received less attention.MethodsWe retrospectively studied 28 patients over the age of 60 years. The aim of this paper was to study the success rate of free tissue transfer and investigate the complication incidence in this patient population.ResultsTwenty-eight free flaps were performed to reconstruct medium to large cervico-facial surgical defects in six years. No difference was noted between success and complication rates observed between general and elderly population.ConclusionThis study indicates that free-flap technique for head and neck reconstruction could be considered a safe option in elderly patients when a good pre-operative general status is present.

Endoscopic Anatomy of the Skull Base Explored Through the Nose

OBJECTIVE Different surgical approaches have been used over the years in order to access skull base. The endoscopic endonasal approach represents a direct and minimally invasive approach to the suprasellar, retrosellar, and retroclival space, with the advantage of avoid brain retraction and visualize safely and effectively the surgical target. The present contribution aims to provide anatomical details of the skull base as seen from below (i.e., via an endoscopic endonasal approach). METHODS Five human cadaver heads were dissected. The anatomical neurovascular structures within the skull base were visualized and carefully described from an endoscopic endonasal view. The advantages and limitations of the endoscopic endonasal route were discussed as well. RESULTS The entire skull base region, as seen from the endoscopic endonasal viewpoint, has been divided in 4 main regions: anterior skull base, middle skull base, posterior skull base and parasellar area. CONCLUSION The development of endoscopic techniques has opened different perspectives over the skull base surgery. Endonasal surgery provides access to a wide range of skull base lesions via a natural surgical corridor (i.e., the nasal cavities).

Open reduction and internal fixation of extracapsular mandibular condyle fractures: a long-term clinical and radiological follow-up of 25 patients

BackgroundDuring the last 2 decades, many studies on the treatment of mandibular condyle fracture have been published. The incidence of mandibular condyle fractures is variable, ranging from 17.5% to 52% of all mandibular fractures. This retrospective study evaluated the long-term clinical and radiological outcomes after surgical treatment of 25 patients with a total of 26 extracapsular condyle fractures.MethodsWe used 2 types of surgical approaches, the retromandibular retroparotid or preauricular approach. Three kinds of rigid internal fixation plates were used—single plate, double plate, and trapezoidal plate. The following post-operative clinical parameters were evaluated: dental occlusion, facial nerve functionality, skin scarring, and temporomandibular joint functionality. All patients underwent post-operative orthopanoramic radiography and computed tomography. The patients were also monitored for complications such as Frey’s syndrome, infection, salivary fistula, plate fracture, and permanent paralysis of the facial nerve; the patient’s satisfaction was also recorded.ResultsOf the 25 patients, 80% showed occlusion recovery, 88% had no facial nerve injury, and 88% presented good surgical skin scarring. The patients showed early complete recovery of temporomandibular joint functionality and 72% of them were found to be asymptomatic. The postoperative radiographs of all patients indicated good recovery of the anatomical condylar region, and 80% of them had no postoperative complications. The average degree of patient satisfaction was 8.32 out of 10. Our results confirm that the technique of open reduction and internal fixation in association with postoperative functional rehabilitation therapy should be considered for treating patients with extracapsular condylar fractures.ConclusionThe topic of condylar injury has generated more discussion and controversy than any other topic in the field of maxillofacial trauma. We confirm that open reduction and internal fixation is the treatment of choice for patients with neck and sub-condylar mandibular fractures.

Multiple myeloma vs. breast cancer patients with bisphosphonates-related osteonecrosis of the jaws: a comparative analysis of response to treatment and predictors of outcome.

BACKGROUND Multiple myeloma (MM) and breast cancer (BC) are the two most common diseases associated with bisphosphonates-related osteonecrosis of the jaws (BRONJ), for which different therapeutical approaches have been proposed. The aim of this study was to compare the clinical behaviour of BRONJ in patients with MM vs. BC and the time of healing in terms of clinical and symptomatological remission, following a standardized therapeutic protocol. METHODS Twenty-six BRONJ patients (13 men with MM and 13 women with BC) were prospectively enroled and treated with a specific systemic and topical antibiotic therapy. Several predictors of outcome were also evaluated. RESULTS Nine patients (69.2%) with BC and 10 patients (76.9%) with MM progressed towards a complete clinical remission (CR) in a mean healing time of 183.3 days [SD: 113.7; 95% confidence interval (CI): 95.95-207.7] and 372.0 days (SD: 308.0; 95% CI: 151.7-592.3) (P = 0.776), respectively. The clinical improvement was statistically significant (P = 0.0013 and P = 0.0014), as well as the assessment of pain (P = 0.0015 and P = 0.0015), in MM and BC group, respectively. Cox regression analysis revealed that just triggering events (P = 0.036) were found to be significant predictors of outcome of BRONJ healing. CONCLUSIONS Both groups of cancer patients experienced clinical and symptomatological remission regardless their malignancy, but BC patients earlier than MM patients.

Head and neck myxofibrosarcoma: a case report and review of the literature.

IntroductionMyxofibrosarcoma is the most common soft tissue sarcoma that occurs in late adult life, peaking in the seventh decade, and it is mainly encountered in the lower extremities. Myxofibrosarcoma of the head and neck are extremely rare. To the best of our knowledge, only 19 cases have been described in the head and neck so far. This is a literature review and retrospective chart review of our experience in head and neck myxofibrosarcoma treatment in our department.Case presentationIn this case report we describe a 35-year-old Caucasian man who presented the first case of myxofibrosarcoma arising from the pterygopalatine fossa. The peculiar anatomical location and the extent in the midcheek region make this case a hard “challenge” for the surgeon, in order to guarantee wide surgical margins of resection. A total right maxillectomy was accomplished by means of the Weber-Ferguson approach, preserving the orbital floor. The excised portion was reconstructed using the free rectus abdominis myocutaneous flap. Postoperative radiotherapy was given to the area adjacent to the lesion, with a total dose of 60Gy. No relapse occurred in the 27-month postoperative follow-up.ConclusionsThe case described suggests the importance of combined surgical and adjuvant radiotherapy to avoid local and distant recurrences of the tumor. In our opinion, combined surgical and adjuvant radiotherapy followed by close clinical observation to search for a metastatic disease is advisable in all cases. Further studies are needed to confirm the efficacy of combined radio-chemotherapy for head and neck myxofibrosarcoma in terms of long-term disease-free survival.

Midcheek mass: 10 year of clinical experience

This is a literature review and retrospective chart review of ten years experience on the treatment of midcheek masses in our department. The purpose of this study is to provide the reader with an overview of the pathology of this complex anatomic area focusing the attention on the differential diagnosis and the recent surgical strategies. From May 2002 to December 2012 we enrolled 22 consecutive patients studied for masses located in the midcheek area. Only four studies were found in the literature describing the experience of individual centres reporting few cases of midcheek masses. Combined with the previously reported 37 cases, we describe 22 lesions for a total of 59 cases. Patients were evaluated with a head and neck clinical and instrumental examination. Apart from 4 cases treated with intramuscular infiltration of botulinum toxin for masseter hypertrophy, surgical approach to the lesions was varied: 10 patients received an external approach (standard parotidectomy approach or face-lift-type approach); 6 patients had the lesion removed through an intraoral approach; in 2 cases a direct skin incision was performed. In our series we found a significant rate (55.5%) of temporary complications in all the procedures performed (external, intraoral, direct skin approach). This study aims to emphasize the role of endoscope assisted surgery as a possible alternative to the traditional approaches for the management of well selected benign midcheek masses. It would be advisable to increase the study of the endoscopic anatomy of the midcheek area in order to standardize the procedure and better define the surgical indications.

Evaluation of discriminative sensibility recovery in patients with buccinator myomucosal flap oral cavity reconstructions

BackgroundSensitive restoration is the primary aim of oral reconstructive surgery. Discriminative sensibility is an important index of innervation density of a tissue. Instruments normally used to assess this type of skin sensibility are bulky and difficult to introduce in the oral cavity, even in healthy patients with a normal mouth opening. This study was intended to evaluate the recovery of static and dynamic two-point discrimination sensitivity of the reconstructed areas of the oral cavity.MethodsSurgical staples, calibrated in predetermined width (from 1 to 30 mm) and introduced in the oral cavity with a Mayo needle holder, were used to evaluate two-point discrimination recovery in 57 patients who underwent reconstructive surgery with buccinator myomucosal flaps. Tests were conducted both on the reconstructive flap and on the non-operated contralateral side. The latter also included the non-operated cheek.ResultsAll of the considered flaps showed a recovery of tactile sensitivity. The overall average discriminative threshold value assessed on this sample was 9.11 ± 2.46 mm for the static and 6.56 ± 2.46 mm for the dynamic.ConclusionsThe use of surgical staples allows easy assessment of tactile sensitivity in all oral cavity areas, even in operated patients who often present lockjaw or microstomia. In our series, buccinator myomucosal flaps demonstrate a much greater recovery of the sensation compared to results found in the literature on fasciocutaneous free flaps, even those reinnervated.Level of Evidence: Level III, prognostic study

Development and Validation of the Quality-of-Life Adolescent Cleft Questionnaire in Patients With Cleft Lip and Palate

Abstract Only a few reports in the literature have described the use of specific instruments for assessing the quality of life in adolescents and young adults with cleft lip and palate (CLP). This condition markedly affects their lifestyle, even after surgical treatment. In the present study, we aimed to develop a quality-of-life assessment tool specifically designed for such patients with CLP. Our multidisciplinary team created a questionnaire focused on the physical, psychological, and social satisfaction of adolescents and young adults with CLP, which was adapted from 3 dimensions of the 36-item Short-Form Health Survey. The questionnaire was administered to a randomized sample of 40 adolescents and young adults (aged 16–24 years) with CLP who had completed treatment protocols and 40 (aged 16–24 years) who were not affected by CLP. The statistical results stated that the questionnaire had good reliability and validity; the Cronbach &agr; coefficient was found to be 0.944. Moreover, factorial analysis confirmed the presence of 3 subscales that were the fundamental components of this questionnaire, which is consistent with the areas theoretically proposed and from which the items were designed and selected. Thus, we validated our novel questionnaire that was administered in the present study and proved its consistency. However, further investigations on a larger population would be useful to confirm these findings.
