RESUMO

PURPOSE: Nasal septal perforation (NSP) consists of defects of mucosa, cartilage, and bone. Nasal septal surgery is by far the most common cause of NSP. Many surgical approaches have been described for NSP repair. In this study, the authors describe a novel technique for repairing all sizes of NSP using an only fascia lata graft. METHODS: The authors implemented a retrospective study design. Seventeen patients who underwent NSP repair between January 2016 and January 2019 were included to the study. Entire nasal surgical steps were performed under endoscopic view, harvested fascia lata graft is placed in tympanoplasty fashion after all edges of perforation is elevated and implantation bed is prepared. RESULTS: The mean size of the septal peforations were 18.52 ±â€Š4.17 mm horizontally, 11.52 ±â€Š3.42 mm vertically. The mean follow up period was 14.47 ±â€Š9.5 months (range: 2-36). In 15 of the 17 patients, total NSP closure was achieved (88,23%). CONCLUSIONS: Endoscopic close technique using fascia lata for nasal septal perforation closure is a safe and reliable technique with high success rate and it should be considered in patients with nasal septal perforation.

RESUMO

Septoplasty is a frequently performed procedure with mostly minor complications. Nevertheless, it may lead to serious complications.The authors present a 29-year-old patient admitted to their hospital 10 days after septoplasty in another institution. He suffered a total loss of vision immediately after the surgery.High-resolution computed tomography and magnetic resonance imaging revealed a direct trauma of the optic canal and an inflamed and edematous optic nerve. Even though a successful endoscopic optic nerve was performed, the patient's loss of vision did not improve after the surgery.Blindness after septoplasty is an extremely rare but a devastating complication. There are only few patients that indicates the optic nerve injury caused by a direct trauma.

RESUMO

Cephalic trimming of the lower lateral cartilage (LLC) of the nose is often performed to refine a broad nasal tip in the horizontal dimension. The focus of cephalic trimming remains the preservation of the width of the lateral crura and the cartilage remnant at the cephalic end of the LLC is usually left intact, which leads to inadequate cephalic trimming.The authors suggest that cephalic trimming should continue all the way to the cephalic end of the LLC and no remnant cartilage should be left in the scroll area. This would make it possible to reduce the bulk of the nasal tip in an acceptable manner. Trimming of the whole cephalic side of the LLC would disrupt the scroll area, allowing authors to assess rhinoplasty as a 2-stage surgical procedure: that is, nasal tip and middle vault.In conclusion, complete cephalic trimming without leaving any remnant cartilage in the scroll area is necessary for adequate nasal tip refinement, and disruption of the scroll area allows the rhinoplasty to be compartmentalized to achieve more desirable results in the middle vault and the nasal tip.

RESUMO

The soft triangle is a basic, yet delicate and vulnerable, subunit of the nose that is under-rated both academically and surgically. The soft triangle is located at the apex of the nostril, at the point where the dermis is in direct contact with dermis that contains no intervening subcutaneous tissue and it may be unintentionally harmed during rhinoplasty.The authors suggest using a modified incision and closure and filling with significantly or severely crushed cartilage to prevent notching and to provide support for the soft triangle. The more the authors understand the nature of the soft triangle, the more they will be able to obtain superior surgical results in the nasal tip area.

RESUMO

Structural deficiencies of the nasal dorsum are most commonly of congenital, traumatic, or iatrogenic etiology. Various grafts, including autografts, homografts, and synthetic materials, have been used to this end and are described in the literature.Autologous septal cartilage is the most commonly used graft material when limited augmentation rhinoplasty is planned. However, it is difficult to retain sufficient cartilage to allow of such augmentation in instances where most of the septal cartilage has been used. The authors place moderately crushed cartilage beneath a monolayer of surgicel when performing limited nasal dorsum augmentation. The aim of the present study is to describe authors' approach and its utility by reviewing other methods reported in the literature.

RESUMO

Routine flexible optic laryngoscopy (FOL) can visualize the airway from the nasopharynx to the hypopharynx in obstructive sleep apnea (OSA). With the tip of a flexible endoscope at the nasopharyngeal inlet (NPI), we can visualize the morphology of this area. We evaluated the effect of NPI morphology on OSA severity. Videos were obtained during FOL examinations of the NPI in 83 patients (11 females, 72 males; mean age 42.1 ± 9.5 years) and NPI morphology was examined. Two main morphologies were seen: wide and narrow. The narrow NPI group (n = 45) was further subdivided into kidney-shaped (n = 34), elliptical (n = 6), and circumferential (n = 5) groups. The wide NPI group (n = 38) was subdivided into circumferential (n = 20) and kidney-shaped (n = 18) groups. Mean Respiratory Disturbance Index (RDI) values were 30.38 ± 22.36 and 14.51 ± 13.9 in the narrow and wide groups, respectively. Mean RDI values were 45.32 ± 30.6, 23.74 ± 10.8, and 28.72 ± 21.5 in the narrow circumferential, elliptical, and kidney-shaped groups, respectively. Mean RDI values were 11.58 ± 12.91 and 17.8 ± 14.6 in the wide circumferential and kidney-shaped groups, respectively. RDI values were significantly lower in the wide morphology group (p < 0.0005). NPI morphology might predict OSA during routine FOL examination. Further analysis of the subgroups supported evidence of narrowing, reflected as higher RDI values.

RESUMO

BACKGROUND: The aim of this study was to compare the incidence of postoperative secondary hemorrhage for tonsillectomy and submucosal uvulopalatopharyngoplasty (smUPPP). MATERIALS AND METHODS: In this retrospective case series, the medical records of 404 patients who underwent tonsillectomy with unipolar electrocautery and smUPPP at our institution between January 2001 and December 2010 were reviewed. The patients were divided into two groups: Group 1 (198 patients) underwent tonsillectomy; Group 2 (206 patients) underwent smUPPP. Main outcome measures were incidence of bleeding or complications after tonsillectomy and smUPPP and the need for revision surgery. RESULTS: The mean age of Group 1 patients was 38.1 (±2.58) years and that of Group 2 was 37.7 (±2.25) years. Males were 51.3% of Group 1 and 46.7% of Group 2. No statistically significant difference in age or gender distribution was found between Groups 1 and 2. The incidence of secondary, delayed hemorrhage was 5.05% (10 patients) in Group 1 and 1.45% (three patients) in Group 2 (P = 0.05). The incidence of delayed hemorrhage requiring surgical treatment was 4.54% (nine patients) in Group 1 and 0.97% (two patients) in Group 2. CONCLUSION: In adults, smUPPP, which includes tonsillectomy, has a lower incidence of postoperative delayed hemorrhage than does tonsillectomy with unipolar cautery.

RESUMO

Flexible optic laryngoscopy (FOL) allows us to visualize the obstructive sleep apnea (OSA)-related airway passages. Retropalatal region is a part of upper airway contributing to the OSA. We aimed to demonstrate the changes in the retropalatal surface area (RPSA) after submucosal uvulopalatopharyngoplasty (smUPPP) in an attempt to exhibit enlargement as a predictor of surgical treatment. It is a prospective, case-control study and conducted at the Otolaryngology department in a university hospital. Twenty patients with OSA who underwent smUPPP were prospectively evaluated. Pre and postoperative respiratory disturbance index (RDI) and RPSA measurements were studied. Retropalatal region videos were obtained at the base of uvula during FOL. Photographic images were captured at the same level of a virtual horizontal line passing through the base of uvula posteriorly to measure RPSAs using AutoCad2004. RDI levels, RPSA measurements were compared using paired t test. Twenty patients underwent smUPPP. There were 17 (85 %) male and 3 (15 %) female. The mean age was 37 years. The RPSA measurements were between 18.41 and 144.102 (mean 63.39) preoperatively. The RPSA measurements were between 83.784 and 255.463 (mean 143.87) postoperatively. The RPSA measurements were significantly enlarged postoperatively (p < 0.0005). The mean RPSA increased from 63.39 ± 29.3 to 143.82 ± 57.8. The mean RDI decreased from 22.95 ± 19.2 to 9.0 ± 8.2 (p = 0.011). RPSA increases in smUPPP patients postoperatively, evidencing enlarged retropalatal region. Decreased RDI levels indicate amelioration in OSA. RPSA measurements can be used to predict UPPP surgical treatment success.

RESUMO

The objective of the study was the assessment of the long-term efficacy of submucosal uvulopalatopharyngoplasty in patients with obstructive sleep apnea syndrome. Thirty-two of 156 patients who underwent UPPP between January 2001 and March 2007 with a follow-up period of 36-96 months (mean, 56 months) were included in the study conducted at the university affiliated center. Preoperative and postoperative snoring evaluation forms and Epworth Sleepiness Scale (ESC) scores were used for subjective analysis. Preoperative and postoperative respiratory distress index (RDI) levels were evaluated objectively. Patients who had 50% or more reduction in RDI levels postoperatively were named as responders to the procedure. The other patients were named as non-responders. Body mass index (BMI) was also analyzed preoperatively and postoperatively. Snoring disappeared in 83% of the patients, did not change in 13% and deteriorated in 4% of the patients (p < 0.001). Excessive daytime sleepiness decreased in 22 patients (68%) and ESC values decreased from 14.6 ± 3.7 to 6.5 ± 3.9 (p = 0.0001). RDI decreased by more than 50% of the preoperative values in 15 (46.9%) of 32 patients forming the responders and the mean RDI decreased from 33.3 ± 22.9 to 23.7 ± 22.8 (p = 0.027). BMI increased over years (p = 0.0001) evidencing a preponderance in non-responder patients. Submucosal uvulopalatopharyngoplasty is an effective tool in treating patient's subjective symptoms of OSAS. Objective findings suggest that smUPPP is inadequate in treating OSAS. It cannot abolish OSAS, though it can decrease the intensity of the condition in nearly half of the patients. Weight gain decreases the success of the procedure over the years.

RESUMO

OBJECTIVE: The purpose of this study was to present the placement technique of Gore-Tex implants for nasal augmentation. METHODS: The study group comprised 32 patients of various nasal deformities who underwent consecutive rhinoplasty via open approach with Gore-Tex implant material for dorsal augmentation. A pocket is made subperiostally at the nasal dorsum. The implant is rinsed in antibiotic solution and placed in position. Complications due to Gore-Tex were observed during the follow-up period. RESULTS: There were 12 men and 20 women. The mean age was 28.4 years. There were 9 primary rhinoplasty and 23 revision rhinoplasty. Patients were followed up postoperatively for 12 to 24 months. During the postoperative follow-up period, no complications were encountered in this series of patients. The implants were stable and immobile under the skin. CONCLUSIONS: In the cases of nasal dorsum augmentation, Gore-Tex can be a suitable graft material. We recommend implanting graft materials at subperiosteal plane to provide better stabilization and low complication rates.

RESUMO

OBJECTIVE: Flexible optic laryngoscopy (FOL) allows us to visualize the obstructive sleep apnea (OSA)-related airway passages. However, objective data presenting evidence of OSA through this perspective are lacking. The aim of this study was to quantify the surface area of the retropalatal region in control subjects and OSA patients utilizing FOL images. This was a prospective, case-control study. The study was performed at the otolaryngology department of a university hospital. SUBJECTS AND METHODS: Sixty-seven OSA patients in group 1 and 87 patients with no complaints of OSA in group 2 were evaluated. Retropalatal region photographs were captured at the base of uvula through endoscopic images. The retropalatal surface area (RPSA) was measured using AutoCAD. Groups 1 and 2 RPSA measurements were analyzed. The RPSA measurements of subgroups in group 1 were analyzed to document severity of OSA. RESULTS: Mean RPSA measurements in group 1 was 73.21 (SD, 31.99), and that in group 2 was 129.31 (SD, 26.54), respectively. Retropalatal surface area is significantly larger in group 2 when compared with group 1 (P = 0.0001). Twenty-four patients had mild (mean respiratory disturbance index [RDI], 10.83 [SD, 3.63], 26 had moderate (mean RDI, 20.9 [SD, 4.14]), and 17 had severe OSA (mean RDI, 52.13 [SD, 17.24]) in group 1. The mean RPSA measurements are 72.48 (SD, 28.9) in mild subgroup, 73.88 (SD, 30.5) in moderate subgroup, and 73.22 (SD, 39.59) in severe subgroup, showing no evidence of correlation between the severity OSA and RPSA measurements. CONCLUSIONS: The RPSA measurements are significantly larger in control subjects (group 2) when compared with OSA patients (group 1). This might implicate that RPSA measurements through FOL examination can be a predictor of OSA when screening patients.

RESUMO

The aim of this study was to document patients with clinical mastoiditis who were reported to have mastoiditis by radiologists due to increased fluid signal intensity in the mastoid air cells on magnetic resonance imaging (MRI). Brain and temporal bone MRI reports between January 2004 and November 2009 were obtained from the radiology units of four different hospitals of the same Health Care Group. MRI reports for keyword mastoiditis and 406 patients were reported to have radiological mastoiditis on MRI due to increased fluid signal intensity. Otoscopic examination findings of 275 of these 406 radiological mastoiditis patients were documented and compared with MRI reports for clinical infectious otological disease. Forty-eight (17, 45%) (48/275) patients were found to have clinical otological disease on examination. The remainder of the patients (227/275, 82%) did not show any evidence of clinical otologic infectious disease. Of these 48 patients, 18 patients (37, 5%) had eustachian tube dysfunction, 13 patients (27%) had serous otitis media, nine patients (9%) had chronic otitis media, five patients (10%) had tympanosclerosis, and three patients (6%) had acute otitis media. The results of this study showed that MRI is not an effective diagnostic tool for mastoiditis. 82% of the MRI mastoiditis did not show clinical mastoiditis contradicting MRI reports. Fluid signal in the mastoid on MRI should not always be interpreted as mastoiditis by radiologists. Radiological mastoiditis does not necessarily point out to clinical mastoiditis.

RESUMO

OBJECTIVES: The goal of the cochlear implant surgery is to place the electrode array with minimal damage to preserve the residual hearing. Round-window insertion can be performed in a manner that is potentially less traumatic than the standard cochleostomy. The purpose of the study was to investigate audiological results of the round-window approach using standard electrode. METHODS: A retrospective study was performed to evaluate our experience in patients with implanted through round window between January 2007 and March 2009. Sixty patients had undergone cochlear implant surgery through the round window with full insertion of a standard electrode array. Preoperative and postoperative pure-tone thresholds were measured for implanted ears in the range of 250 to 4000 Hz. RESULTS: Within these 60 cases, 31 patients had been evaluated. The population comprised 16 women and 15 men. The mean age was 15.96 years (range, 4-64 years). Follow-up times ranged from 6 to 26 months. Preservation of low-frequency hearing (250 and 500 Hz) was achieved in 27 (87%) of 31 patients. Complete hearing preservation (all frequencies) was accomplished in 11 patients (35.48%). No hearing could be determined postoperatively in 4 patients (12.9%), having preoperative thresholds of 120 dB at 250, 500, and 1000 Hz. CONCLUSIONS: Round-window approach has been widely used for preservation of residual hearing. In our patients with severe to profound hearing loss, we preserved residual hearing. Although the residual hearing cannot be sufficient for using additional acoustic stimulation, the preserved residual hearing means minimal damage and a more convenient cochlea, so this is promising for future development.

RESUMO

BACKGROUND: The aim of this retrospective chart review of the patients who had septal surgery with or without turbinate surgery was to compare the postoperative complication rates according to the time of intranasal-splint (INS) removal. METHODS: The data of 137 patients who underwent septal surgery with or without turbinate surgery at 2 different hospitals of Acibadem Health Care Group between January 2007 and March 2009 were retrospectively evaluated. The patients who had these risk factors were eliminated, and 96 patients were included in this study. The patients were divided into 2 groups according to splint-removal time. The first group comprises patients whose nasal splints were removed in 24 hours after surgery, and the second group comprises patients whose splints were removed 5 days after the surgery. Any bleeding, septal hematoma, and synechia after pack removal were recorded. Analysis of the rate of complications was done with the χ test. RESULTS: Sixty-five male and 31 female patients with a mean age of 32.4 years (range, 18-57 years) were included in the study groups. Septal surgeries were performed in association with turbinate surgery in all 96 patients. These patients were divided into 2 groups. In the first group (n = 50), INSs were removed in 24 hours after surgery. In the second group (n = 46), INSs were removed 5 days after surgery. Bleeding within the first postoperative week was not recorded in both groups. Late bleeding was recorded in 2% (n = 1) of group 1 and in 2.17% (n = 1) in group 2. Septal hematoma and synechia were not recorded in none of the groups. The results were not statistically significant (P = 1). CONCLUSIONS: The routine use of INSs after septoplasty and removing them 24 hours after septoplasty are sufficient to avoid postoperative complications, and it minimizes postoperative discomfort.

RESUMO

This study was undertaken to evaluate and concentrate on the recurrent pleomorphic adenomas (PAs) of the parapharyngeal space. The records of 9 patients treated for recurrent PAs occupying parapharyngeal space were retrospectively reviewed. The study population comprised 6 women and 3 men with a mean age of 51 (range, 35-79 years). Before the first revision surgery, imaging studies and clinical examinations showed 1 solitary mass in 4 patients, 2 solitary masses in 3 patients, and 3 or more masses in 2 patients. After first revision surgery, 4 patients had rerecurrences with multinodular disease. Two of 4 patients underwent radiation therapy (RT), and the other 2 patients underwent second revision surgery, among whom 1 patient underwent third revision surgery, and the other one was also submitted to RT. Overall, 12 reoperations were performed, and at the end of all operations, 4 patients had rerecurrences and residual disease. In conclusion, we recommend RT to patients with multinodular disease, known tumor spillage, and residual tumor in addition to revision surgery. Histopathologic features, surgical resection, relationship to surrounding vital tissues, and postoperative adjuvant radiotherapy are the most important determinants for recurrent PAs.

RESUMO

BACKGROUND: This study aimed to assess and compare the tissue response to small- and large-volume injections of pure liquid silicone in rats. METHODS: The study used 25 Sprague-Dawley rats. Two different injection sites were determined for a single rat, and 5000 centistoke liquid silicone was injected subdermally using 0.2-0.3 ml (small volume) and 1 ml (large volume) injections. After the injections, 15 animals were killed at 4 weeks and 10 animals at 10 weeks. Tissue responses were evaluated under a light microscope. RESULTS: At week 4, the numbers of lymphocytes and neutrophils were higher in the small-volume injection group. At week 10, the number of neutrophils decreased, and the numbers of macrophages and foreign body giant cells increased in the small-volume injection group, whereas the intensity and type of infiltrate in the large-volume injection group did not change significantly. The thickness of the fibrous capsule was greater in large-volume injection group at weeks 4 and 10. The thickness of the fibrous capsule did not change significantly in either group through time. CONCLUSIONS: Purified high-density liquid injectable silicone causes a low-grade and well-tolerated inflammatory response during the long term and can be used when given as small-volume injections.

RESUMO

OBJECTIVES: This study aims to show the placement of extended spreader grafts in reductive septorhinoplasty operations to support the nasal bony vault as well as the middle cartilaginous structures. PATIENTS AND METHODS: Thirty-eight patients (16 males, 22 females; mean age 26.4 years; range 18 to 55 years) who underwent septorhinoplasty under general anesthesia via open approach between January 2008 and December 2010 were included in this study. Two separate cartilage grafts were placed end-to-end and secured to the septum on both sides after removing the cartilage and bony hump. These grafts not only transverse the full length of the middle one-third of the nose, also run approximately 1 cm under the nasal bones cephalically and the anterior septal angle caudally on both sides. The obtained data were evaluated retrospectively. Patients were followed up postoperatively for 7 to 24 months with a mean follow-up of 14 months. RESULTS: There was no significant bony vault collapse or irregularity, inverted-V deformity or middle-vault narrowing observed during the postoperative period. All of the patients were satisfied with the cosmetic and functional results. CONCLUSION: We think that extended spreader grafts are more beneficial not only in reconstructing the middle one-third of the nose but also in supporting the collapsed and/or distrupted nasal bony vault in reductive septorhinoplasty.

RESUMO

PURPOSE: Temporal bone fracture, which involves the otic capsule, can lead to complete loss of auditory and vestibular functions, whereas the patients without fractures may experience profound sensorineural hearing loss due to cochlear concussion. Cochlear implant is indicated in profound sensorineural hearing loss due to cochlear trauma but who still have an intact auditory nerve. MATERIAL AND METHODS: This is a retrospective review study. We report 5 cases of postlingually deafened patients caused by cochlear trauma, who underwent cochlear implantation. Preoperative and postoperative hearing performance will be presented. These patients are cochlear implanted after the cochlear trauma in our department between 2001 and 2006. RESULTS: All patients performed very well with their implants, obtained open-set speech understanding. They all became good telephone users after implantation. Their performance in speech understanding was comparable to standard postlingual adult patients implanted. CONCLUSION: Cochlear implantation is an effective aural rehabilitation in profound sensorineural hearing loss caused by temporal bone trauma. Preoperative temporal bone computed tomography, magnetic resonance imaging, and promontorium stimulation testing are necessary to make decision for the surgery and to determine the side to be implanted. Surgery could be challenging and complicated because of anatomical irregularity. Moreover, fibrosis and partial or total ossification within the cochlea must be expected.

RESUMO

Variation in nasal-tip deformity is the most common complaint of the patients requesting rhinoplastic surgery, and the goal of nearly every rhinoplasty is to achieve ideal nasal-tip rotation and projection. We describe a procedure that allows the surgeon to secure nasal-tip rotation and projection through a suspension suture technique. Preserving the interalar soft tissues over the dorsal caudal septum and interdomal ligaments during the surgery is the major basis of this technique. We use the soft tissues as a suspending material for the tip complex, which acts like one whole part.
