RESUMEN
OBJECTIVE: The objective of this study was to evaluate the graft outcomes and iatrogenic cholesteatomas for 3 years following cartilage-perichondrium over-underlay technique with perichondrial graft covering the epithelium for large-sized tympanic membrane (TM) perforations. MATERIALS AND METHODS: This prospective case series enrolled patients with large-sized perforation who underwent endoscopic cartilage-perichondrium over-underlay technique. The graft success rate, hearing outcomes, and development of iatrogenic middle ear cholesteatomas and graft cholesteatomas were assessed at 3 years postoperatively. RESULTS: This study included 62 ears of 62 patients. The mean follow-up duration was 47.3 ± 10.8 (38-64) months. Neovascularization was observed in the lateral perichondrium graft in 55 (88.7 %) patients, which inosculated into the TM remnant at 4-5 weeks. However, graft neovascularization was not observed in the four patients with excessive perichondrium graft that migrated into the external auditory canal and the three patients with middle ear infections. The graft failure rate was 6.5 % at 6 months, 11.3 % at 12 months, 6.5 % at 24 months, and the overall graft success rate was 91.8 % at the last follow-up. Granular myringitis developed in 11.3 % (7/62) of the patients. High-resolution computed tomography revealed well-pneumatized mastoids and middle ear at the final follow-up. However, graft cholesteatomas were observed in 3 (4.8 %) patients at 7-24 months postoperatively. CONCLUSIONS: The cartilage-perichondrium over-underlay technique with perichondrial graft covering TM epithelium is safe and effective for the repair of large perforations, with good short- and long-term graft outcomes, minimal risk of graft cholesteatoma development, and no risk of iatrogenic middle ear cholesteatomas.

OBJECTIVE: To compare the graft success rates and hearing outcomes of underlay myringoplasty with or without perichondrium tucking of the attached perichondrium, graft perforation margins when repairing chronic large central dry perforations. STUDY DESIGN: Randomized controlled trial. MATERIAL AND METHODS: Chronic large central dry perforations were prospectively randomized to tucking perichondrium graft underlay (TPGU) and no-tucking perichondrium graft underlay (NTPG) groups. The graft outcomes and complications were compared between the two groups at 12 months postoperatively. RESULTS: In total, 61 patients with large central dry perforations were included. All patients completed 12-month follow-ups. Residual perforations occurred in 0.0 % of the TPGU group and in 12.9 % of the NTPG group (P = 0.129), and re-perforations occurred within 6 months in 0.0 % and 3.2 % of the two groups, respectively (P = 0.987). The graft success rates were 100.0 % (30/30) and 83.9 % (26/31) (P = 0.067). No significant between-group differences were observed in terms of preoperative (P = 0.547) or postoperative (P = 0.612) air bone gaps (ABGs) or mean ABG gains (P = 0.597). No graft-related complications were observed in either group during follow-up. No patients exhibited significant graft blunting or medialization; graft lateralization was noted in one patient of the NTPG group. CONCLUSIONS: Endoscopic cartilage with tucking of the attached perichondrium perforation margins during underlay myringoplasty may improve the graft success rate compared to that of the cartilage push-through technique when repairing large central dry perforations; however, the hearing improvements were comparable in the two groups.
RESUMEN
OBJECTIVE: The objective of this study was to compare the operation time, graft success, audiometric outcomes and complications of over-under technique using a temporalis fascia (TMF) and cartilage grafts for the repair of large perforations. STUDY DESIGN: Randomized controlled trial. MATERIALS AND METHODS: 80 large perforations >2 quadrants of eardrum were prospectively randomized to undergo TMF over-under technique group (TFON, n = 40) or cartilage-perichondrium over-under technique group (CPON, n = 40). The graft success rate, audiometric outcomes, and complications were compared among two groups at 12 months. RESULTS: The mean operation time was 56.8 ± 4.2 (range:52-71) min in the TFON group and 37.9 ± 2.8 (range: 31-47) min in the CPON group (P < 0.001). The lost follow-up rate was 3 (7.5 %) patients in the TFON group and 2 (5.0 %) patient in the CPON group (P = 0.644). Finally, 37 patients in the TFON group and 38 patients in the CPON group were included in this study. The graft infection rate was 2 (5.4 %) patients in the TFON group and 2 (5.3 %) patient in the CPON group (P = 0.626), all the graft infection resulted in the residual perforation. The remaining residual perforation was 2 (5.4 %) patients in the TFON group and 1 (2.6 %) patient in the CPON group; the re-perforation was 3 (8.1 %) patients in the TFON group and 0 (0.0 %) patient in the CPON group. The graft success rate was 81.1 % (30/37) patients in the TFON group and 92.1 % (35/38) patient in the CPON group. The mean preoperative and 12-month postoperative ABGs were significantly different in any group (P < 0.01). However, there were no significant difference among two groups regardless of pre-or post-ABGs or ABG closure. No lateralization of the graft or blunting was noted in any group. Four (10.8 %)patients developed atelectasis and one (2.7 %) developed the EAC scarring in the TFON group. Graft cholesteatomas was found in 2 (5.4 %) patients in the TFON group and in 5 (13.2 %) patients in the CPON group (P = 0.449). Three (8.1 %) patients had temporary hypogeusia in the TFON group. CONCLUSION: Although temporalis fascia graft over-under technique obtained similar graft success rates and hearing outcomes for large chronic perforations to the cartilage-perichondrium over-under technique, temporalis fascia graft technique prolonged the operation time and increased the re-perforation and graft atelectasis. Nevertheless, the graft cholesteatomas were comparable among two techniques.

OBJECTIVE: In this study, graft success, hearing outcome, and complications were compared following the repair of subtotal perforation using a cartilage reinforcement underlay technique (CRUT) versus the traditional cartilage underlay technique (TCUT). STUDY DESIGN: Randomized controlled trial. MATERIALS AND METHODS: Seventy-six patients with subtotal perforations were prospectively randomized to the CRUT (n = 38) or TCUT (n = 38) group. The graft success rate, hearing outcome, and complications were compared at 12 months. RESULTS: The mean operation time was 32.9 ± 4.2 (range: 26-47) min in the CRUT group and 51.8 ± 6.3 (range: 48-73) min in the TCUT group (P < 0.001). At 12 months postoperatively, no residual perforation was seen in either group. The graft success rate was 94.7 % (36/38) in the CRUT group and 92.1 % (35/38) in the TCUT group; the difference was not significant (P = 0.643). The postoperative air bone gap (ABG) was significantly improved compared to the preoperative value in both groups, without significant between-group differences in either the preoperative (P = 0.741) or postoperative (P = 0.865) ABG or the mean ABG gain (P = 0.812). Additionally, there were no significant between-group differences in the preoperative (P = 0.887) or postoperative (P = 0.753) mean bone-conduction pure tone average. In the TCUT group, seven (18.4 %) patients developed temporary hypogeusia and two (5.3 %) had external auditory canal scarring. Graft cholesteatoma was not observed in either group. CONCLUSION: In the treatment of subtotal perforations, lateral reinforcement of the annulus with additional cartilage is simpler than traditional cartilage underlay for achieving graft and hearing success. The technique also does not involve raising the tympanomeatal flap or removing perforation margins.

OBJECTIVE: The objective of this study was to compare the graft outcomes and complications of two endoscopic perichondrium-cartilage graft techniques for repairing large perforations. STUDY DESIGN: Single center blinded randomized controlled trial. MATERIALS AND METHODS: 61 large perforations more than 50% of TM area were prospectively randomized to undergo the free perichondrium and free cartilage graft group (FPFC, n = 31) or perichondrium partial attachment the cartilage graft group (PPAC, n = 30). The primary outcome measures were the operation time; secondary outcome measures were the graft success rate and hearing gain at 12 months postoperatively and postoperative complications. RESULTS: All patients completed follow-up of 12 months. The mean operation time was 38.2 ± 2.3 min in the FPFC group and 37.4 ± 5.6 min in the PPAC group (P = 0.658). At postoperative 3 months, the graft success rates were 96.7% in the FPFC group and 93.3% in the PPAC group (P = 0.976). At postoperative 12 months, the graft success rates were 96.7% in the FPFC group and 83.3% in the PPAC group (P = 0.182). However, the residual and re-perforation rate with no infection was 0.0% (0/31) in the FPFC group and 16.7% (5/30) in the PPAC group (P = 0.056). No significant between-group differences were observed pre- (P = 0.842) or post- (P = 0.759) operative air bone gap (ABG) values or mean ABG gain (P = 0.886). However, granular myringitis has been noted in 6.5% in the FPFC group and in 3.3% in the PPAC group. CONCLUSIONS: This study suggested that 12-month graft success and hearing gain were comparable between the perichondrium free and partial attachment the cartilage graft techniques, nevertheless, partial attachment technique could increase residual and re-perforations.

OBJECTIVE: To evaluate the efficacy of Low-temperature plasma radiofrequency ablation (RF) tuboplasty and myringotomy for treating chronic otitis media with effusion (COME) with chronic obstructive eustachian tube dysfunction (COETD) involving hypertrophic tissue of the ET orifice. METHODS AND MATERIALS: This was a prospective study of 43 ears with COME and COETD who underwent RF tuboplasty. Outcomes included the ability to perform a Valsalva maneuver, tympanometry results, and TM status. Success was defined by an improvement in tympanogram type and Valsalva maneuver. Follow-up ranged from 4 weeks to 12 months. RESULTS: A total of 43 ears (43 patients) were included in the study. Mucosal hypertrophy of the ET orifice was seen in 35 (81.4 %) patients, while polypoid tissue was observed in 8 (18.6 %) patients. All patients completed the 12-month follow-up, the success rate was 95.3 % (41/43) at postoperative 3 months, 39/43 (90.4 %) at postoperative 6 months, and 37/43 (86.0 %) at postoperative 12 months. No procedure-related serious adverse events were reported for any patient, and there were no cases of patulous ET. Stenosis/scar of anterior-post wall in the ET orifice occurred in two patients at 6 months postoperatively and in one patient at 12 months postoperatively, which the Valsalva maneuver was positive. Thus, no further treatment was applied for the ET orifice in 3 patients. The risk of stenosis of the ET orifice was 3/47 (6.4 %). CONCLUSIONS: RF eustachian tuboplasty may be an effective treatment for patients with COME, COETD and hypertrophic mucosa in the ET orifice, particularly as an adjunct to balloon tuboplasty.

OBJECTIVE: The objective of this study was to evaluate graft outcomes and complications of endoscopic perichondrium-cartilage H type technique for repairing chronic kidney-shaped perforation with 3 years of follow-up. MATERIAL AND METHODS: Adult patients with chronic kidney-shaped perforation underwent endoscopic perichondrium-cartilage H type technique. The graft outcomes and complications were evaluated at 36 months after surgery. RESULTS: The total of 51 ears were included in this study. The mean operation time was 31.5 ± 4.1 min. Residual perforation was seen in 2 patients, the graft success rate was 96.1 % (49/51) at postoperative 12 months. Granular myringitis was noted in 8.2 % (4/49) patients in 49 patients with graft success. The mean preoperative ABG was 23.6 ± 3.7 dB, while the mean postoperative ABG postoperatively 12 months was 12.9 ± 5.2 dB (P < 0.05), the functional success rate was 94.1 % (48/51). At postoperative 36 months, only 32 (62.7 %, 32/51) patients were followed up, while 19 (37.3 %, 19/51) patients lost followup. Of the 32 patients with followup of 36 months, the mean follow-up time was 38.2 ± 7.1 (37-46) months, re-perforation was seen in one. All 32 patients performed the postoperative CT examination at last followup, CT revealed the well pneumatization of mastoids and middle ear. CONCLUSIONS: Endoscopic cartilage-perichondrium H type technique is an alternative method for repairing chronic kidney-shaped perforations, with a highly successful, short operation time, minimally invasive procedure, and no cholesteatoma.

OBJECTIVE: The objective of this study was to compare graft outcome, operation time and surgical complications of the double and single perichondrium-cartilage underlay techniques for repairing subtotal tympanic membrane (TM) perforations. MATERIALS AND METHODS: Patients with unilateral subtotal perforations undergoing myringoplasty were prospectively randomized to undergo DPCN or SPCN. The operation time, graft success rate, audiometric outcomes, and complications were compared between these groups. RESULTS: In total, 53 patients with unilateral subtotal perforations were included (DPCN group, 27; SPCN group, 26).All patients completed 6 months of follow-up. The mean operation time was 41.2 ± 1.8 min in the DPCN group and 37.2 ± 5.4 min in the SPCN group, the difference was not significant (p = 0.613).The graft success rates were 96.3% (26/27) in the DPCN group and 73.1% (19/26) in the SPCN group, the difference was significant (p = 0.048). During the period of follow-up, residual perforation was found at postoperative in one (3.7%) in the DPCN group, while cartilage graft slipped (graft lateralization) in 2 (7.7%) and residual perforation in 5 (19.2%) were found in the SPCN group, the difference of residual perforation was not significant among two group (p = 0.177).In addition, no significant between-group differences were observed pre- (p = 0.741) or post- (p = 0.687) operative ABG values or mean ABG gain (p = 0.659) (Table 2).The functional success rates (postoperative ABG ≤ 20 dB) were 85.2% (23/27) in the DPCN group and 73.1% (19/26) in the SPCN group (p = 0.454). CONCLUSION: Although similar functional result and operation time can be obtained with double perichondrium-cartilage underlay technique compared to the single perichondrium-cartilage underlay technique for endoscopic closure of subtotal perforations, double unerlay technique offers better anatomical result with minimum complications.

OBJECTIVE: The aim of this study was to determine the long-term efficacy of four steps of operation on the treatment of maxillary sinus (MS) inverted papilloma (IP). METHODS: 83 patients who were diagnosed with IP that originated from the MS, underwent four step procedure of attachment sites, including mucosal stripping, periosteum ablation, bone drilling and bone ablation and had postoperative follow-up of 3 years were enrolled. RESULTS: Of the 83 patients, 59 (71.1%) patients were primary surgery and revision surgery in 24 (28.9%), single attachment was in 31(37.3%) patients and multifocal attachments in 52 (62.7%).When the numbers were not mutually exclusive, the most common origin sites of IPs were the medial wall in 54 (37.2%), lateral wall in 29 (20.0%), anterior wall in 18 (12.4%), inferior wall in 22 (15.2%), posterior in 15 (10.3%), and superior wall in 7 (4.8%). Large MMA alone was performed in 5 (6.0%), MMA combined with medial maxillectomy 76 (91.6%), and MMA combined with Caldwell-Luc approach in 2 (2.4%). No major intra- or postoperative complications were observed. The average follow-up was 41 months (range, 37-61 months). CT and endoscope showed that tumor and symptom recurrence occurred in 2 patients (2.41%). In addition, although the opening of antrostomy was closed and CT revealed the uniform soft tissue shadow and hyperostosis of MS in 11(13.3%) patients, they didn't report any symptoms and showed well epithelization of middle meatus mucosa. CONCLUSION: The four steps of operations of attachment sites of MS IP, including mucosal stripping, periosteum ablation, bone drilling and bone ablation, may effectively prevent the recurrence of MS IP.

OBJECTIVE(S): This clinical study was performed to analyze the characteristics of cholesterol granuloma (CG) and evaluate our results in children. METHODS: The clinical records of children diagnosed with CG were retrospectively reviewed. RESULTS: The total of 17 children (20 ears) with CGs were included in this study. Endoscopy revealed pars flaccida retractions and lipoid tissue deposition behind the intact blue tympanic membrane (TM). CT scan revealed bony erosion and extensive soft tissue in the middle ear and mastoid. No ossicular chain destruction was found. All 20 ears underwent canal wall-up mastoidectomy and ventilation tube (VT) insertion, 3 sets of VT were performed in 5 ear and 2 sets in one. The residual perforation was seen in 2 ears following VT. The CT revealed well-pneumatized antra and tympanic cavities at postoperative 12-24 months. CONCLUSION(S): The CG should be suspected for the patients with yellow lipoid deposition behind the blue TM. CT of CG usually revealed bony erosion and extensive soft tissue in the middle ear and mastoid. Mastoidectomy combined with VT insertion and etiological treatment have a favorable prognosis for CG in children.

OBJECTIVE: To compare the intraoperative records and postoperative clinical outcomes of adults who underwent coblation and modified monopolar tonsillectomy tonsillectomies. MATERIALS AND METHODS: Adult patients with tonsillectomy were randomly divided into the coblation and modified monopolar tonsillectomy groups. The estimated blood loss, postoperative pain score, operation time, post-tonsillectomy hemorrhage (PTH), and cost of disposable equipment were compared. RESULTS: Pain intensity in the coblation and monopolar groups was similar on postoperative days 3 and 7. However, the mean maximum pain score in the monopolar group was significantly higher compared to the coblation group on postoperative days 1 (P < 0.01) and 2 (P < 0.05).Secondary PTH occurred in 7.1% (23/326) of patients in the coblation group and 2.8% (9/327) of patients in the monopolar group (P < 0.05). CONCLUSION: Although pain was significantly increased on postoperative days 1 and 2 in the modified monopolar tonsillectomy group, the operation time, secondary PTH, and medical costs were significantly decreased compared to the coblation technique group.

OBJECTIVE: The objective was to compare the recurrence rate and complications between endoscopic middle meatal antrostomy (MMA) and extended MMA for the treatment of antrochoanal polyps (ACPs). METHODS AND MATERIALS: 95 ACPs were prospectively enrolled to undergo MMA (n = 48) or extended MMA (n = 47). The recurrence rate and complications were compared between these groups. RESULTS: All patients completed 24 months of follow-up. The recurrence of ACP was demonstrated by only endoscope at 6 and 12 months postoperatively but at 24 months postoperatively by endoscope and CT. Rates of recurrence of ACP differed between groups and significance at postoperative month 6 (7/48 patients in the MMA group and 0/47 patients in the extended MMA group, P = 0.02), month 12 (16/48 vs. 2/47, P < 0.01) and month 24 (21/48 vs. 3/47, P < 0.01). No MMA closure was found in any group, 19.15% (9/47) patients complained of cheek numbness in the extended MMA group, however, no major complications were observed in both groups. CONCLUSIONS: Extended MMA via antidromic extended medial wall of MS may effectively reduce the recurrence of ACP with lower complications.

OBJECTIVE: This study evaluated the graft success rate and hearing outcomes of the inside-out raising mucosal-tympanomeatal flap technique for the repair of large marginal perforations. STUDY DESIGN: Prospective case series. MATERIALS AND METHODS: The study enrolled patients with large marginal perforations who underwent endoscopic cartilage myringoplasty with the inside-out raising mucosal-tympanomeatal flap technique. The graft success rate, hearing outcomes, and complications were evaluated at 12 months postoperatively. RESULTS: In total, 48 patients with large marginal perforations were included. 81% of the population had large perforation, 14.6 had subtotal and total perforation was seen in 4.2%. The mean operation time was 38.6â ±â 7.1 min. At 12 months postoperatively, the graft success rate was 89.6% (43/48). The mean air-bone gap was 25.6 ± 5.2 dB preoperatively and 16.5 ± 4.1 dB at 12 months postoperatively, with significant differences between these values (p = 0.001). The functional success rate was 85.4% (41/48). None of the patients experienced worsened sensorineural hearing loss or graft-related complications, such as graft lateralization, significant blunting, and graft medialization, during follow-up. CONCLUSIONS: Endoscopic cartilage-perichondrium myringoplasty for the repair of large marginal perforations using the inside-out raising mucosal-tympanomeatal flap technique was associated with satisfactory graft outcomes and minimal complications.

OBJECTIVE: We explored the outcomes and voice parameters of patients undergoing plasma radiofrequency (RF) ablation to treat intubation granulomas. STUDY DESIGN: Prospective case series. METHODS AND MATERIALS: Patients with intubation granulomas who met the inclusion criteria underwent RF ablation. The complete remission rate and voice function were evaluated preoperatively and at 6 months postoperatively. RESULTS: We enrolled 13 patients with 25 intubation granulomas. The mean time between intubation and initial diagnosis was 38.6 days and that between intubation and surgical diagnosis was 2.7 months. All 25 granulomas were successfully removed and histologically confirmed. No surgical remnant was evident on the vocal folds and complete glottal closure was observed at 2 weeks postoperatively. No recurrence or RF ablation-related complications were observed during the 6-month follow-up. The complete remission rate was 100% (13/13). In addition, the mean hoarseness, roughness, breathiness, asthenia, and strain (GRBAS) scores, and the maximum phonation time (MPT), improved significantly after treatment (all P < 0.05). CONCLUSIONS: RF ablation is effective and safe for patients with intubation granulomas who failed medical management or request the procedure. In this study, the complete resolution rate was high and voice restoration outcomes were good.

OBJECTIVE: To identify the factors predicting postoperative recurrence after cold steel excision for the market trader with idiopathic vocal process granulomas (VPGs). MATERIAL AND METHODS: The market traders with idiopathic VPGs who do not respond to medical treatment were treated by cold steel excision. The factors considered likely to affect the recurrence were evaluated by univariate and multivariate logistic regression. RESULTS: The total of 80 idiopathic VPGs underwent the cold steel excision. All postoperative 6 months, the complete remission rate was 37.5% (30 VPGs) and 50 recurrences developed (62.5%). The recurrence rate was not significantly associated with sex (P = 0.119), side (P = 0.468), VPG size (P = 0.726), LPR (P = 0.293), diabetes mellitus (P = 0.5611), cerebrovascular disease (P = 0.129), or chronic pulmonary disease (P = 0.190). Multivariate logistic regression showed that only vocalization frequency (P = 0.006) and smoking and alcohol consumption (P = 0.001) were independent predictors of recurrence. There was no significant correlation between age and recurrence (P = 0.59). However, recurrence was more common in those aged 51-60 years than those aged ≥61 years (P = 0.019). Of the recurrent 49 VPGs treated conservatively via behavioural modification and oral deanxit, the granulomas disappeared spontaneously in 38 (77.6%) within 6-10 months and in 11 (22.4%) within 2-3 years. CONCLUSIONS: The market traders with VPG would be a high recurrence rate after cold steel excision, the frequency of voice use and smoking and alcohol consumption were significant independent predictors of recurrence. Antidepressant medications and behavioural modification could effectively improve the outcome of VPG.

OBJECTIVE: This study was performed to compare the efficacy of the endoscopic modified cartilage over-underlay technique with and without packing for repairing chronic tympanic membrane (TM) perforations. METHODS: A total of 70 cases of chronic TM perforation were randomly allocated to endoscopic modified cartilage over-underlay myringoplasty groups with (n = 35) and without (n = 35) packing. The graft success rate and hearing outcomes were compared between the two groups. In addition, neovascularization scores were subjectively obtained. RESULTS: At 12 months postoperatively, the difference in graft success rate between the packing and no-packing groups was not significant (94.3% vs. 100.0%, P = 0.473). In addition, there were no significant differences between the two groups in the pre- or postoperative air-bone gap (ABG) (15.18 ± 2.73 vs. 15.07 ± 4.02, P = 0.623 and 8.63 ± 3.03 vs. 8.52 ± 4.50, P = 0.591) or mean ABG gain (6.56 ± 3.23 vs. 6.54 ± 2.83, P = 0.751). However, the average operating times were 43.6 ± 7.1 and 32.7 ± 2.1 min in the packing and no-packing groups, respectively (P < 0.001). CONCLUSIONS: Surgical and hearing outcomes were comparable between patients with chronic TM perforation treated using the endoscopic modified over-underlay technique with and without packing. However, without packing, the procedure was less invasive and had a shorter operating time.

OBJECTIVE: We compare the long-term efficacy of the cartilage-perichondrium modified over-underlay technique and transtympanic underlay alone technique using endoscopic myringoplasty without tympanomeatal flap elevating for repairing large chronic perforations. MATERIAL AND METHODS: Nine chronic large perforations with mucosal chronic otitis media were recruited and randomly allocated to endoscopic cartilage-perichondrium modified over-underlay myringoplasty (MOUM, n = 55) and endoscopic cartilage-perichondrium transtympanic underlay alone myringoplasty (TUAM, n = 54). The graft success rate, hearing gain, mean operation time and postoperative complications were compared between the groups at 6 and 24 months. RESULTS: In total, 99 patients were finally analysed. The graft success rates 6 months after surgery between MOUM and TUAM groups were not significantly different (100.0% vs 96.0%, p = 0.484). However, the MOUM group had a significantly higher success rate 24 months after surgery than the TUAM group (93.9% vs 76.0%, p = 0.028). In addition, postoperative ABG < 10 dB was 73.5% patients in the MOUM group and 76.0% in the TUAM group, the difference wasn't significant (p = 0.953). CT examination revealed well-pneumatised middle ears 24 months after surgery in both groups, and no middle ear cholesteatoma was observed. CONCLUSION: Endoscopic modified cartilage-perichondrium over-underlay myringoplasty without tympanomeatal flap elevating is reliable and effective for repairing large perforations. It improves the long-term graft success rate compared to the endoscopic cartilage-perichondrium transtympanic underlay alone technique. The risk for iatrogenic cholesteatoma is minimal.

OBJECTIVE: The objective of this study was to compare the long-term results of extended middle meatal antrostomy (MMA) and MMA combined with inferior meatal antrostomy (IMA, combined approach) for the treatment of fungal maxillary sinusitis (FMS). METHODS AND MATERIALS: A retrospective analysis including 90 patients with non-invasive FMS was treated with endoscopic extended MMA via antidromic extended medial wall (extended MMA group), or with both MMA and IMA (combined approach group). The recurrence rate, operation time, and complications were evaluated at postoperative 12 and 36 months. RESULTS: Of the 90 patients, 52 patients were in the extended MMA group and 38 patients in the combined approach group. CT revealed the thin medial wall or bone defect in 63.33% (57/90) patients. The mean operation time in the extended MMA group was significantly shorter than that of combined approach group (42.5 ± 6.5 vs 57.4 ± 4.9, P < 0.01). At postoperative 12 months postoperatively, the recurrence rate was 3.85% (2/52) in the extended MMA group and 0.0% (0/38) in the combined approach group, the difference wasn't significant (X2 = 0.618, P > 0.05). The recurrence rate wasn't increased during the follow-up period over time in both groups.13.5% (7/52) patients complained of cheek numbness in the extended MMA group, 60.5% (23/38) patients complained of cheek numbness and epiphora in 5.3% (2/38) patients in the combined approach group, the difference was significant (X2 test, P < 0.01). However, no major complications were observed in both groups. In addition, IMA closure was observed in 4 (10.5%) in the combined approach group at 12 months postoperatively and in 9 (23.6%) at 36 months postoperatively. CONCLUSIONS: Extended MMA via antidromic extended medial wall may effectively prevent the recurrence and reduce the complications of FMS, IMA wasn't necessary for the treatment of FMS in most cases.

OBJECTIVE: To compare the outcome of endoscopic transtympanic cartilage myringoplasty with and without removal of perforation edges for repairing chronic perforations with mucosal chronic otitis media (COM). STUDY DESIGN: Quasi-randomised clinical trial. SETTING: Tertiary referral centre. MATERIALS AND METHODS: Patients with chronic perforations and mucosal COM undergoing endoscopic transtympanic cartilage myringoplasty were allocated to a control group for whom the perforation edges were preserved (n = 40) and an intervention group for whom the edges were removed (n = 39). Mean operation time, graft success rate, mean scores of graft neovascularisation and epithelialisation, and hearing were compared between the groups at 4 weeks and/or 6 months postoperatively. RESULTS: Graft success rate was 95% (38/40) in the control group and 97% (38/39) in the intervention group at 6 months postoperatively; the difference was not significant. Mean graft neovascularisation scores 4 weeks postoperatively were 2.52 ± 0.59 in the control group and 2.58 ± 0.55 in the intervention group; the difference was not significant. Mean graft epithelisation scores 4 weeks postoperatively were 1.48 ± 0.57 in the control group and 1.68 ± 0.51 in the intervention group; the difference was not significant and remained nonsignificant 6 months postoperatively (2.5 ± 0.55 vs. 2.76 ± 0.36). Audiological outcomes at 6 months did not differ between the groups. CONCLUSION: Endoscopic, transtympanic cartilage underlay myringoplasty with preservation of the perforation margins did not affect graft neovascularisation, epithelialisation or success. Longer-term outcomes and risk of cholesteatoma require further study.

OBJECTIVE: The aim of this study was to investigate the feasibility of intranasal endoscopic microwave ablation (MWA) on the management of postoperative ethmoid sinus mucoceles. METHODS AND MATERIALS: The patients with postoperative ethmoid sinus mucoceles were ablated through intranasal endoscopic MWA. Postoperative pain intensity was measured via visual analogue scale (VAS), post-operative complications were recorded. RESULTS: Of the 26 patients with unilateral postoperative ethmoid sinus mucoceles, the mucoceles were diagnosed 3 to 11 years with average time of time of 6.9 ± 2.7 years after endoscopic ethmoidectomy. The ipsilateral middle turbinate was present and intact in 24 patients and partially resected during the original surgery in the remaining 2. There were adhesions in the middle meatus in one case. All 26 patients were successfully treated with the intranasal endoscopic ablation technique in outpatient. The ablation time was 6 to 11 min, with an average duration of 6.84 ± 1.27 min. The mean VAS pain score was 2.41 ± 1.22. There were no perioperative complications reported in this series. No evidence of recurrence was observed in any patients during follow-up periods. CONCLUSIONS: The present study demonstrates the safety and efficacy of intranasal endoscopic MWA in the office. The procedure is well tolerated by patients with low complication rates. Thus, it is alternative to conventional endonasal endoscopic marsupialization for treatment of postsurgical ethmoid sinus mucoceles.
