From Nov. 1988 through Apr. 1994, 78 cases with laryngocarcinoma underwent laryngectomy and laryngeal reconstruction by the use of transfered cervical skin. Three to six months after operation, all patients were subjected to direct or indirect laryngoscope. It was found that the keratinized of layer of the transfered skin tended to be thining out, and that hair had grown in one case. With the followup ranging from 3 months to 5 years,the results were good. All patients following the reconstruction of larynx could phonate, swallow and breath. Postoperatively, 32 patients were alive for 3 years, 2 patients died from recurrence of laryngocarcinoma. The complications included laryngeal fistula in 6 cases and laryngostenosis in 2 cases. The cause as well as the prevention of complications were discussed. It was suggested that thetransfer of cervical flap was feasible for laryngeal reconstruction.
【摘要】目的探討喉癌手術后患者對兩種不同霧化方式的耐受性,為選擇最佳霧化方式提供參考。方法將49例喉癌手術后患者隨機分為觀察組(25例)和對照組(24例),觀察組采用氧氣霧化吸入,對照組采用空氣壓縮泵霧化吸入。分別記錄兩組患者霧化吸入前及吸入15 min時脈搏血氧飽和度(SpO2)及心率;霧化過程中患者有無心慌、氣緊等不適以及霧化后痰液的性質及量。采用SPSS 13.0軟件進行統計分析。結果兩組患者霧化吸入15 min時的SpO2差異有統計學意義(Plt;001),觀察組高于對照組;而兩組患者霧化吸入前SpO2、心率、不適主訴及霧化后痰液的性質差異均無統計學意義(Pgt;005)。結論氧氣霧化吸入可以提高喉癌手術后患者霧化過程中的SpO2,使患者感覺更加舒適。【Abstract】Objective To investigate postoperative patients with laryngeal carcinoma atomization of two different forms of tolerance, in order to choose the best means of atomization. Methods Fifty postoperative patients with laryngeal carcinoma were divided into observation group using oxygen inhalation and control group using the air compression pump inhalation. Two groups of patients were recorded the value of SpO2 and heart rate before 15 minutes after the inhalation,as well as the discomforts such as flustered,gas tight during the atomization process and the nature and olume of sputum. Results The results of two groups of patients at the time of 15 minutes inhalation SpO2 statistically significant difference (Plt;001), the observation group than in the control group average SpO2 high; and two groups of patients with preinhalation SpO2 average, average heart rate, Discomfort chief complaint and the nature of sputum after aerosol compared no significant difference (Pgt;005). Conclusion Oxygen inhalation in patients with laryngeal cancer can improve the atomization process SpO2 value, so that patients feel more comfortable.
ObjectiveTo objectively evaluate the effectiveness of the ventricular fold pull-down combined with strip myofascial flap to repair laryngeal defect after early glottic carcinoma operation with glottic morphological parameters and voice parameters.
MethodsBetween January 2008 and December 2012, 47 patients with early glottic carcinoma and anterior commissure involvement underwent partial laryngectomy. All patients were male, aged from 60 to 75 years (mean, 68.5 years). The disease duration was 4-11 months (mean, 7.2 months). According to American Joint Committee on Cancer (AJCC) TNM criteria, 28 cases were classified as T1aN0M0, 14 cases as T1bN0M0, and 5 cases as T2N0M0. Laryngeal defect after resection of tumor was repaired by ventricular fold pull-down combined with strip myofascial flap. At 1 day before operation and at 1 year after operation, multilayer spiral CT was used to scan larynx, to measure and compare the anteroposterior diameter of vocal area, the distance between both sides of the vocal process, and the thickness of soft tissue of vocal area, and the effect of combined soft tissue flap was objectively assessed in laryngeal morphology reconstruction. The actual voice parameters[including F0, Jitter, Shimmer, normalized noise energy (NNE), and maximum phonatory time (MPT)] were tested and compared, and the effect of the combined soft tissue flap on postoperative laryngeal pronunciation was evaluated.
ResultsPostoperative pathological examination revealed well-differentiated squamous cell carcinoma in 38 cases, and moderately-differentiated squamous cell carcinoma in 9 cases; no tumor was found in the resection margin. Healing of neck incision was obtained in all patients at 7-9 days after operation. Forty-four cases were decannulated at 9-11 days after operation and the remaining 3 cases were decannulated at 3 weeks after operation. Oral feeding usually started in all cases at 3-4 days after operation. All patients were followed up 1 year. At 1 year after operation, the anteroposterior diameter of vocal area was significantly reduced when compared with preoperative one (t=15.161, P=0.000); the distance between both sides of the vocal process and the thickness of soft tissue of vocal area had no significant changes (P > 0.05). Compared with preoperative ones, there were significant differences in Shimmer, NNE, and MPT (P < 0.05), but no significant difference was found in F0 and Jitter (P > 0.05) at 1 year after operation.
ConclusionVentricular fold pull-down combined with strip myofascial flap can repair laryngeal defect effectively after partial laryngectomy and maintain the effective airway after operation. It not only has no effect on postoperative laryngeal morphology, but also can be used as new laryngeal voice vibration body.
Objective
To study the effectiveness of one-stage repairing pharyngeal defect with the tongue flaps after resection of advanced stage hypopharyngeal neoplasm and laryngeal neoplasm.
Methods
Between June 2006 and March 2011, 20 patients with hypopharyngeal neoplasm (8 cases) and laryngeal neoplasm (12 cases) with advanced stage were treated. There were 19 males and 1 female, aged 47-78 years (mean, 62.8 years). All neoplasms were squamous cell carcinomas. The disease duration was 1-8.5 months (mean, 3.9 months). According to the standards of International Union Against Cancer (UICC, 1987), 12 cases were in stage III and 8 cases were in stage IV. The size of pharyngeal defect was 5 cm × 2 cm to 4 cm × 4 cm after resection of tumor. Defects were repaired by the whole base of the tongue flaps in 16 cases and by the horizontal base of the tongue flaps in 4 cases. The size of the flaps ranged from 5 cm × 2 cm to 4 cm × 4 cm. Postoperative radiotherapy and chemotherapy were regularly performed.
Results
The 20 tongue flaps were alive. Healing of incision by first intention was achieved in 18 cases and delayed healing in 2 cases because of subcutaneous fluid. The patients were followed up 12-63 months (mean, 36.7 months). The patients had normal feeding ability and tongue function. Of 20 cases, 12 died and 1 of local recurrence was alive with tumor. The 3-year survival rate was 69.2% (9/13).
Conclusion
One-stage repair of pharyngeal defect with the tongue flaps after resection of hypopharyngeal neoplasm and laryngeal neoplasm can obtain good effectiveness because the tongue flap is easy-to-obtain and easy-to-survive, and has abundant blood supply.
Objective To evaluate the expression and clinical significance of Survivin in the tissues of laryngeal carcinoma using meta-analysis. Methods The case-control studies published in China about the expression and association of clinical pathogenic features of Survivin in the tissues of laryngeal carcinoma were electronically retrieved in CBM (1994 to October 2012), CNKI (1994 to October 2012), VIP (1989 to October 2012) and WanFang Data (1996 to October 2012). The reviewers independently identified the literature according to inclusion and exclusion criteria, extracted data, and assessed the quality of the included studies. Then, meta-analysis was performed using RevMan 5.1 software. Results A total of 25 studies were included, involving 1 333 cases of laryngeal carcinoma and 528 cases of health laryngeal mucosa or polyp of vocal cord. The results of meta-analysis showed that, significant differences were found in groups of laryngeal carcinoma vs. health control, laryngeal carcinoma with vs. without lymphatic metastasis, clinical stages I-II vs. III-IV, cell differentiation G1 vs. G2-G3, T1 and T2 stages vs. T3 and T4 stages, and glottic carcinoma vs. non-glottic carcinoma (Plt;0.05). No significant difference was found in groups of age more than 60 vs. no less than 60, male vs. female, and smoke vs. non-smoke (Pgt;0.05). Conclusion Current domestic evidence shows that Survivin may be associated with the whole course of occurrence, advance and transfer of laryngeal carcinoma, and positively correlated to degree of tumor malignance, which may indicate poor prognosis.
ObjectiveTo explore the feasibility of reconstruction of phonatory function by using a tubular free flap from upper-lateral upper arm to repair the laryngotracheal circumferential defect after near-total laryngectomy for laryngeal cancer. Methods A retrospective study was conducted on 7 patients who underwent near-total laryngectomy between June 2021 and October 2023, aged from 48 to 70 years (median, 59 years), 6 males and 1 female. The disease duration ranged from 1 to 11 months, with a median of 6 months. Pathological diagnosis of preoperative biopsy was squamous cell carcinoma. Tumor classification: glottic type in 5 cases, supraglottic type in 1 case, transglottic type in 1 case; TNM staging: T4N0M0 in 6 cases, T4N2M0 in 1 case; American Joint Committee on Cancer (AJCC) staging in 2017 was stage Ⅳ. Preoperative MRI angiography of upper arm was performed to investigate the blood supply in the upper and lateral regions of the upper arm. After near-total laryngectomy and bilateral neck lymph node dissection, the area of the laryngotracheal defect was measured. A free flap measuring 7.0 cm×5.0 cm to 8.0 cm×7.0 cm was harvested from the upper-lateral upper arm, rolled into a tube shape, and connected between the stump of the cervical trachea in the neck root and that of the epiglottis at the tongue base. Four patients received adjuvant radiochemotherapy, 1 patient received radiochemotherapy and targeted therapy, 2 patients adopted no further adjuvant treatment. Results All 7 patients were followed-up 1-2 years (mean, 1 year and 3 months). Four patients had primary wound healing, 2 patients had minor pharyngeal fistulas that healed after dressing change, 1 patient experienced pharyngeal fistula because of flap necrosis and the wound still healed without secondary surgery. All patients took food orally within 1 month after operation, and the tracheal cannula was retained. Six patients with survived flap gradually adapted to their new pronunciation mode and obtained satisfactory phonatory function from 15 days to 2 months after operation. Four patients had slight aspiration after operation. Till the end of the follow-up, all patients survived and no local recurrence or distant metastasis had been observed. The motor function of the upper arm was not affected, only partial sensory loss occurred in the area near the incision. The scar of the incision could be covered by the short sleeve so as to obtain a better aesthetic effect. ConclusionUsing a tubular free flap from upper-lateral upper arm to repair the laryngotracheal circumferential defect after near-total laryngectomy for laryngeal cancer can achieve satisfactory phonatory restoration while preserve the motor function and aesthetics of the donor site.
Objective To explore the feasibility and effectiveness of repairing surgical defect in pharyngo-laryngeal malignant tumor with free rectus femoris flap. MethodsThe clinical data of 34 patients with surgical defects in pharyngo-laryngeal malignant tumor who met the selection criteria between July 2014 and August 2024 were retrospectively analyzed. There were 25 males and 9 females, aged 25-82 years, with a median age of 54 years. The disease duration ranged from 2 months to 2 years, with a median of 7 months. The tumor locations included the oropharynx, hypopharynx, cervical esophagus, and larynx. Pathological types included squamous cell carcinoma (29 cases), myoepithelial carcinoma (2 cases), adenoid cystic carcinoma (1 case), and diffuse large B-cell lymphoma (2 cases). TNM staging: 16 cases of T4N1M0, 3 cases of T4N2M0, 3 cases of T4N0M0, 10 cases of T3N1M0, and 2 cases of T3N0M0. The 2017 American Joint Committee on Cancer (AJCC) staging was stage Ⅲ in 2 cases and stage Ⅳ in 32 cases. The blood supply of the proximal rectus femoris muscle was observed by enhanced CT of the lower limb vessels before operation, and the surgical defects ranged from 3.0 cm×2.0 cm to 12.0 cm×8.5 cm. The blood supply and perforators of rectus femoris muscle were explored during operation, and the free rectus femoris flap pedicled with the direct vascular stem of rectus femoris muscle was used to repair the defect. For the patients with pharyngeal fistula or obvious neck swelling after operation, the blood supply of the flap was analyzed by vascular enhanced CT to determine the corresponding strategies of nutritional support, anti-infection, dressing change and drainage. Radiotherapy and chemotherapy were supplemented in 27 patients with lymph node metastasis after operation. Results All the 34 patients were followed up 1-10 years, with an average of 3 years. The flap was found to be necrotic by fibrolaryngoscopy at 1 week after operation in 2 cases, and the incision healed after dressing change and nutritional support, and no reoperation was performed. The flap was in good condition at 1 week after operation in 4 cases, and the signs of gradual necrosis of the flap were found within 1 month after operation, of which 2 cases were healed after dressing change, 1 case was removed the necrotic tissue by reoperation, and 1 case was healed after pectoralis major myocutaneous flap was used to repair the pharyngeal tissue defect. The flaps survived in 28 cases, including 4 cases of pharyngeal fistula, which healed by dressing change. Twenty-two cases achieved satisfactory results in swallowing or phonation. Two patients with total laryngectomy and voice reconstruction underwent reoperation to seal the voice tube because of postoperative aspiration. During the follow-up, 1 case had tracheal stomal recurrence, 2 cases had bone metastasis, and 1 case had bone and lung metastasis. Conclusion The free rectus femoris flap has good flexibility, the volume of the flap is easy to adjust, and the incision of the donor site is concealed, which is expected to become a new choice for the repair of the surgical defect in pharyngo-laryngeal malignant tumor.
