FRENECTOMY WITH Z PLASTY TECHNIQUE FOR HIGH ABERRANT FRENUM (FRENEKTOMI DENGAN TEKNIK Z-PLASTY PADA ABERANSIA FRENULUM YANG TINGGI

An aberrant frenum can cause gingival recession and plaque accumulation due to a muscle pull. It also presents an aesthetic problem and inhibits the orthodontic result in a case with midline diastema, thus causing a recurrence after the treatment. This case report describes how periodontal surgery can accomplish such an aberrant frenum like a frenectomy procedure. This case report shows the abnormal maxillary labial frenum removal in a 21-year-old through the Z-plasty technique. The Z Plasty was made with an angulation of about 60° on the left and right sides of the vertical incision to obtain a double rotational flap. The two flaps were then transposed to the opposite side of the apex of each flap for relief of soft tissue tension. This pattern has shown uneventful healing and minimized scar formation, which was favorable in aesthetics.

The Z-Plasty Technique on the Frenectomy Approach of the Aesthetic Gingival Recession In Frenulum Labial Mandibular Case

The frenulum is an anatomical structure in the oral cavity. Its formed folds of mucosa membranes attach the lip and the cheek to the alveolar mucosa, the gingiva, and the underlying periosteum. Abberansia frenulum is one of the causes of aesthetic and functional problems such as gingival recession, which occurs either due to plaque control or muscle pull issues. One of the treatment options for the anomaly of the frenulum case is by performing a frenectomy procedure. This paper aimed to explain using the z-plasty technique in abberansia frenulum treatment with hypertrophy frenum associated with midline diastema and short vestibule. A 36-year-old female patient came to Periodontic Clinic in Oral dan Dental Hospital, Universitas Padjajaran, Bandung, Indonesia, with chief complaint pain in 41 teeth, and clinically the gingiva appears recession and short vestibule. This situation is alarming in terms of aesthetics and functionality. The treatment of frenectomy with the z-plasty technique is an indication for this case. The frenectomy with the z-plasty method has shown favorable results in aesthetics and functional appearance. The z-plasty technique helped in reducing soft tissue tension so that it can minimize scar formation

Objective: To study surgical management of post-burn scar extension contractures of the toes. Methods: The treatment outcomes of 72 children with post-burn scar extension contractures of the toes between the ages of 3-15 were analysed. There were 38 boys (52.8%), girls – 34 (47.2%). In 14 (19.4%) children, both feet were affected, with a total of 86 feet with extension contracture. In most cases (n=53, 73.6%) of children (62 feet), retracting scars extending proximally also caused extension contracture of the ankle joint. Results: In all cases, a modified Z-plasty (butterfly flap) technique, according to Hirshowitz, was used to correct scar contracture of the anterior ankle. In 89.5% of patients (77 feet) after reconstruction using a local flap, soft tissue defects (range, 6-30 cm2) remained. The defects were covered with full-thickness autologous skin grafts. In this case, in 32.6% (28 feet), the exposed tendons and cutaneous nerves were preliminarily covered by the surrounding subcutaneous tissue and fascia used as a blood-supplying source. Local flap surgery helped reconstruct mild scar contracture in 16 (18.6%) feet. In 21 (24.4%) cases, tendon-articular structures were reconstructed. Complications in the early postoperative period were observed in 7 out of 86 operated feet, which amounted to 8.1%. In all cases, complications included marginal necrosis of local flaps and transplanted full-thickness skin grafts observed in 4 feet (4.6%) and 3 (3.5%) feet, respectively. In all cases, engrafting of a full-thickness skin graft was noted; and there was no complete recurrence of contracture. Due to the somatic growth of children in 8 cases (9.3%) in the late postoperative period (after 6-10 years), repeated corrective surgical procedures were required. Conclusion: In children, burn contractures of the toes require surgical intervention on the skin and soft tissue. Unfortunately, the pathological process is almost always accompanied by a lack of skin and soft tissue, requiring skin grafts. In the long term, there is a need for repeated corrective surgical interventions. Keywords: Post-burn contracture, skin autografts, foot contracture, local flap surgery.

How I do it: lateral canthal web revision—single Z-plasty technique

BackgroundLateral canthal webbing is a known complication of blepharoplasty, which occurs when the lateral aspect of the upper blepharoplasty incision is taken below the equator of the lateral canthus. Removing excessive eyelid skin laterally can also result in a lateral canthal web. Currently, there is no standard approach for addressing this complication.MethodsRetrospective review of single surgeon practice between 2011 and 2019. All patients underwent revision surgery using the proposed single Z-plasty technique.ResultsTwenty-three patients referred for lateral canthal web were included in the study. All patients had previous upper lid blepharoplasty, with the initial procedure occurring 8–63 months prior to the referral for revision. The majority of the blepharoplasties occurred in Ontario (n = 19), but some patients also underwent surgery in Alberta (n = 1), British Columbia (n = 1), and United States (n = 1). The initial surgeries were performed by a variety of specialities including plastic surgery (n = 16), otolaryngology (n = 4), ophthalmology (n = 2), and family medicine (n = 1). Following revision surgery using the single Z-plasty technique, all patients reported a subjective increase in functional and aesthetic satisfaction. No further revision surgery was required for any of these patients.ConclusionThe single Z-plasty technique is simple, robust, and could be easily incorporated into any cosmetic practice to address this complication of blepharoplasty.Graphical

Incidence of fistula after primary cleft palate repair: a 25-year assessment of one surgeon's experience.

BackgroundCleft lip and cleft palate are the most frequent congenital craniofacial deformities, with an incidence of approximately 1 per 700 people. Postoperative palatal fistula is one of the most significant long-term complications. This study investigated the incidence of postoperative palatal fistula and its predictive factors based on 25 years of experience at our hospital.MethodsWe retrospectively reviewed 636 consecutive palatal repairs performed between January 1996 and October 2020 by a single surgeon. Data from patients’ medical records regarding cleft palate repair were analyzed. The preoperative extent of the cleft was evaluated using the Veau classification system, and the cleft palate repair technique was chosen according to the extent of the cleft. SPSS version 25.0 was used for all statistical analyses, and exploratory univariate associations were investigated using the t-test.ResultsFistulas occurred in 20 of the 636 patients; thus, the incidence of palatal fistula was 3.1%. The most common fistula location was the hard palate (9/20, 45%), followed by the junction of the hard and soft palate (6/20, 30%) and the soft palate (5/20, 25%). The cleft palate repair technique significantly predicted the incidence of palatal fistula following cleft palate repair (P=0.042). Fistula incidence was significantly higher in patients who underwent surgery using the Furlow double-opposing Z-plasty technique (12.1%) than in cases where the Busan modification (3.0%) or two-flap technique (2.0%) was used.ConclusionsThe overall incidence of palatal fistulas was 3.1% in this study. Moreover, the technique of cleft palate repair predicted fistula incidence.

Surgical Correction of Congenital Macrostomia with Double Z-Plasty technique: A Case Report

Abstract: Introduction: Congenital macrostomia is a relatively rare congenital facial anomaly that can occur either alone or in association with other facial anomalies and present either unilaterally or bilaterally. Purpose: To report the management of macrostomia with good functional and aesthetic results. Case report: A 3-months-old baby girl with widening at right corner of the lip since birth. Case management: Surgical correction was done with double Z-plasty to correct the macrostomia. Conclusion: Surgical correction of macrostomia in infant patient should be done promptly in young age to provide good psychological impacts on both child and family. Macrostomia reconstruction with double Z-plasty technique is the simplest one and easy to yields good results in both functional and aesthetics aspects. In the present case, there was minimal scar and no lateral deviation of the commissure after 2 weeks follow up.

A Novel Method for Correction of the Tethered and Contracted Facial Scars: The Three-Dimensional Subcutaneous Z-Plasty

Scar revision is 1 of the basic surgery in the field of plastic and reconstructive surgery. The classic treatment of the scar is excision scarless tissue, wide undermining and suture by planes. This method has had unsatisfying results on contracted and tethered scars. The aim of this study is to present the three-dimensional subcutaneous z-plasty technique for correction of tethered facial scars without scar lengthening. Twenty tethered scars were corrected using this technique. All scars were located on the face. Objectively, the final result was evaluated by using the Stony Brook Scar Evaluation Scale. Subjectively, patients' overall satisfaction was assessed 1 year after the surgical operation. In addition, the information on the age, gender, etiology, scar location, scar length, type of anesthesia, and follow-up period were examined. This procedure was used in nineteen patients (8 males and eleven females). The mean follow-up period was 15.3 months. There was a mean increase of 2.85 points increase in the Stony Brook Scar Evaluation Scale value. The overall success rates for the procedure, as assessed by the patients, were: very satisfied in 12 patients, satisfied in 5 patients, and slightly satisfied in 2 patients. One patient had minimal wound dehiscence. No complications including hypertrophic scar, infection, hematoma, and suture reaction were observed in any patients. The three-dimensional subcutaneous z-plasty technique is a procedure that uses only basic plastic surgery principles. It offers a good solution for the correction of tethered and contracted scars without recurrence. This technique combines the advantages of elliptical excision and z-plasty by enabling the augmentation of the depressed area without extending the scar length.

Satisfaction and health-related quality of life of patients with microtia following reconstructive surgery using the Nagata technique.

This study aimed to investigate the functional outcomes, satisfaction, and quality of life of patients with microtia following reconstructive surgery. This cross-sectional study was conducted using retrospective data of patients with microtia following reconstructive surgery using the Nagata technique. Data were obtained from the medical records of patients who underwent reconstructive surgery at the Division of Facial Plastic and Reconstructive Surgery, Department of Otorhinolaryngology, Head and Neck Surgery, Dr. Cipto Mangunkusumo Hospital between 2014 and 2018. All eligible patients were referred to participate in this study between November 2018 and March 2019. The hearing function was assessed by a professional audiologist after surgery. Patient satisfaction was evaluated by interview using a previously developed questionnaire, while quality of life was assessed using the EuroQol-5D-Young questionnaire. Thirty-one eligible subjects were included in the study. Pain and discomfort were the most commonly reported factors related to the quality of life following surgery. Approximately 67.7% of the patients were satisfied; 19.4% were very satisfied, and 12.9% reported acceptance of their surgical outcomes. The most common complication was infection (n = 8). Most patients did not experience any problems in their lives after microtia surgery. The highest rate of satisfactory outcomes was observed for the lobule subunit, which was assumed to be associated with the use of the Z-plasty technique. The most common complication was infection, as environmental hygiene was the most important factor. Thus, further concern for maintaining good hygiene is necessary to improve the quality of reconstructive surgery. The level of satisfaction with microtia reconstructive surgery was adequate. Most patients had a good health-related quality of life without experiencing any problems.

A Comparative Study on flap necrosis following Karydakis Flap Reconstruction and Z-Plasty in Patients with Sacrococcygeal Pilonidal Disease – Our experience

Aim: The purpose of this study was to evaluate patients with sacrococcygeal pilonidal sinus disease(SPSD) who underwent the Karydakis procedure and Z plasty at our centre concerning theperioperative findings, late postoperative results and recurrence. Patients and Methods: A total of30 patients presenting with SPSD at our centre underwent Karydakis flap repair and Z plasty fromMay 2019 to June 2021. These patients were then followed up and evaluated concerning operativetime, drain use, hospital stay, suture removal, complications, and recurrence. The adipocutaneousflap of Karydakis was devised to shift the natal cleft, while Z-plasty involves a fasciocutaneous flap.Results: The mean operative time was 60 min with a median hospital stay of 4 days. Drains wereremoved at a median of 5 days and sutures at a median of 15 days. The duration of hospitalisationfor the Karydakis procedure was found significantly lesser than that for Z-plasty Patients who werefollowed up for a median of 12 months. The overall complications were more in Z-plasty. Flapnecrosis developed in 30 % of the cases in the Z-plasty group, comparable to no recurrence seen inthe Karydakis procedure. Conclusion: Karydakis flap was found superior to Z-plasty, having lessseroma formation, no flap necrosis and no local hematoma Karydakis flap procedure is a relativelysimple procedure for SPSD and has advantages over Z-plasty technique like keeping scar away fromthe midline and flattening of the natal cleft, thus reducing local recurrence rates.

Unique hybrid double apposing flap in a Z-plasty technique to reconstruct major perianal defect resulting from chondyloma acuminatum resection - Case report.

Perianal area is anatomically challenging location to reconstruct after wide extensive local excision especially when preserving the anus anatomy anal sphincter continence is a requirement. That is the case in many benign locally aggressive conditions, due to high risk of suture line disruption, wound dehiscence, and wound infection. Many surgical options like primary closure, loco reginal flaps, distant or pedicled flaps, or even free flaps are available for such reconstruction. This is a report of a case of locally aggressive infection that was initially confused as complex perianal fistula, then sarcoma after the initial resection. Surprisingly, the permanent pathology confirmed the diagnosis of a giant condyloma acuminatum extending to the anal area, for which an extensive wide local resection with margin and temporary colostomy was done, this resulted in a large defect necessitating a reconstruction with hybrid double apposing Superior gluteal artery perforator flap (SGAP flap) and Inferior gluteal artery perforator flap (IGAP flap) in Z-plasty fashion. That healed completely with no local complication.

Endoscope-assisted greater neurovascular palatal bundle release in cleft palatoplasty

Performing surgery in the oral cavity is difficult because of the limited view of the surgical field. Intraoral surgery for infantile oral disorders, such as cleft palate, is even more challenging. Endoscopy provides a minimally invasive approach and clear surgical view in surgeries with a constrained field of view. To date, very few reports have described endoscope-assisted palate surgery for children with cleft palate. At the authors’ institution, endoscopes have been used in primary palatoplasty using the double-opposing Z-plasty technique. A novel endoscope-assisted procedure is described herein, in which a dissection around the greater palatine neurovascular bundle is used to obtain tension-free closure of the palatal cleft. With this technique, it was possible to minimize the application of additional von Langenbeck-type relaxation incisions, which were previously introduced in most of our cases; the relaxation incision was successfully circumvented in 42.3% of cases. This led to lesser surgical interference, which possibly resulted in favourable palatal development. It was also found that the endoscopic procedure did not increase the operation time or blood loss when compared to those patients who underwent the non-endoscopic procedure. It is concluded that endoscopic guidance is quite useful in primary palatoplasty procedures with a constricted surgical view.

Experience of Two Different Techniques of Medial Epicanthoplasty with Four-Point Homologous Design: A Cohort Study.

Various methods have been introduced to eliminate the epicanthus; however, there are no clear guidelines to determine the optimal technique for epicanthus. We aimed to investigate the clinical effect of modified Z-plasty and modified Y-V flap on epicanthus and report our experience. Medical records, including photographic information and scar score, of 81 eyes of 43 patients with congenital epicanthus were collected. All patients underwent epicanthus correction surgery by the modified Z-plasty or modified Y-V flap methods with a four-point design from January 2018 to December 2019 in Shanghai Ninth People's hospital and completed a follow-up of at least 6 months. The cosmetic outcome was evaluated in terms of by photographic evaluation and scar score, and the structural outcome was assessed by intercanthal distance (ICD) and palpebral fissure length, inner canthal angle, the canthal tilt angle. The results of two surgical techniques were compared and analyzed. The cosmetic outcome of both group is good in both groups. ICD is smaller and inner canthal angle is larger in modified Z-plasty group, compared to modified Y-V flap group, respectively (P < 0.05). Patients with severe epicanthus in the modified Z-plasty group showed greater improvement in structural outcomes than in the modified Y-V flap group (P < 0.05), while those with mild epicanthus in the modified Y-V flap group showed more improvement in ICD than those in the modified Z-plasty group (P < 0.05). By 6 months, scarring in the modified Z-plasty group was more hypertrophic and obvious compared to the modified Y-V flap group (P < 0.05). Modified Y-V flap technique caused less scarring. Conversely, the modified Z-plasty technique was more efficient in shortening the ICD and increasing inner canthal angle. While modified Z-plasty reconstruction is more suitable for patients with severe epicanthus, the modified Y-V flap is more suitable for patients with mild epicanthus.

Revisional Medial Epicanthoplasty Using Reverse Z-Plasty Technique.

Medial epicanthoplasty is a common method for correcting epicanthal folds in Asians but sometimes cause unsatisfactory results. Although several procedural variations have been devised, revision techniques have earned little attention. The revision technique the authors have developed employs reverse Z-plasty to restore an overcorrected epicanthal fold. The aim of this study was to investigate the effectiveness of the authors' reverse Z-plasty technique in restoring natural medial canthal region harmonizing with Asian face. From January 2010 to December 2016, reverse Z-plasty was performed in patients seeking revisions after previous medial epicanthoplasties. Patients were surveyed to assess their satisfaction with surgical outcomes. Interepicanthal distance-lengthening ratios and symmetry of palpebral widths were evaluated digitally (ImageJ software) in patients who received revisional epicanthoplasty only. The reverse Z-plasty technique for revisional epicanthoplasty was performed in 548 Asian patients (83 males, 460 females). Most patients were pleased with the final outcomes. Only 6% submitted to later revisions of scars, which were otherwise scarcely visible after 3 months. Among 60 patients who underwent only revisional epicanthoplasty, interepicanthal distance-lengthening ratios ranged from 2.9% to 31.1% (average, 8.6%), and palpebral width symmetries improved. This particular technique helps restore the 3-dimensional appearance of medial canthal angle through horizontal skin and soft tissue (including muscle and ligament) restructuring, thus compensating for tissue deficiency. It is simple in design, easy to perform, and satisfactory results were achieved, conferring natural aesthetics to the medial canthal region.

Z- Plasty: an Effective Technique for Pilonidal Sinus

Introduction: Pilonidal sinus is a commonly encountered problem with multiple surgical options. With Z- plasty, primary closure ensues faster healing while the alteration of local anatomy reduces recurrence. The extremely low recurrence rate following Z-plasty for pilonidal sinus results from the fact that the operation was planned with the true physiology of the disease in mind. It is the deep natal cleft which predisposes to pilonidal sinuses and this architecture is altered with multiple Z -plasty.&#x0D; Materials and methods: A prospective, observational study was conducted into department of Plastic Surgery and burn, Dhaka Medical College and Hospital. Here 18 patients with pilonidal sinus were treated by Z – plasty between 2013 to 2018.&#x0D; Result: There was only one recurrence during the follow up time. There were no necrosis of flaps and no wound dehiscence.&#x0D; Conclusion: The Z-plasty technique is an effective procedure for treating pilonidal sinus in terms of both faster healing and lower recurrence rate.&#x0D; J Dhaka Medical College, Vol. 28, No.2, October, 2019, Page 164-171

A comparative study of wide excision and Z-plasty in the management of pilonidal sinus at tertiary care hospital

Background: Treatment of pilonidal disease is challenging to surgeon. Post-operative course is lengthy, painful and patients are often unsatisfied. Several treatment modalities have been tried for pilonidal disease including incision & drainage of abscess, excision with primary closure, excision with open packing, excision with marsupilization and recently flap surgery. The aim of present study was to compare the results of wide excision and Z-plasty technique in management of pilonidal sinus.Materials and Methods: The present study was conducted on 50 cases diagnosed as a case of pilonidal sinus and admitted in department of surgery of Dr. S. N. Medical College Jodhpur. Patients were randomly divided into two groups. In Group A, wide excision was done and Group B wide excision was followed by Z-plasty.Results: Wound infection was present in 32% of Group A and 16% of Group B patients as postoperative early complication. Localized loss of sensation observed in 16% of Group A and 24% of Group B patients. Postoperative pain was present for 36.6±1.22 days in Group A and 14.32±1.83 days in Group B. Total healing of wound was reported in 42.2±2.62 days in Group A and 16.6±1.99 days in Group B. Mean days for return to work was 34.64±2.66 days in Group A and 15.44±1.80 days in Group B.Conclusion: Excision with Z-plasty was better technique in terms of less post-operative complications, less time in healing of wound, and early days for return to work.

Evaluation of Results of the Furlow’s Modified Technique in the Management of Cleft Palate in the Teaching Hospital of Conakry

Introduction: Cleft palate (CP) is a congenital dysmorphosis that results from a failure of the palatal processes of the maxillary buds and nasal septum to merge. The objectives of this study were to determine the frequency of complications of the modified Furlow technique and to evaluate its anatomical and functional outcomes. Materials and Method: This was a retrospective study that took place over a period of 4 years (from January 1st, 2015 to December 31th, 2018) in the Department of Odontostomatology and Maxillofacial Surgery at the National Hospital of Donka (Conakry, Guinea). Data retrieval consisted of records from patients operated on for cleft palate according to Furlow’s modified technique only. The operative technique consisted of marginal incisions of the cleft according to the technique of the double Z-plasty of Furlow. Subsequently, the defect created between the 2 flaps and the anterior edge of the cleft was filled by two fat masses of Bichat sutured to each other with Vicryl 3-0. Four years after surgery, the patients were recalled for an evaluation of the anatomical and functional results. Results: 13 patients underwent surgical loading according to the modified Furlow technique. The average age of the patients was 6.9 years with an age range of 7 months and 17 years. Females were the most affected, with 61.54% of cases and a sex ratio of 0.62. The primary repair rate was 84.61% of cases. Immediate operative follow-up was simple with epithelialization of the flaps in all patients. Four (4) years after the surgeries, 12 patients were reevaluated (92.30%), among them one case (8.33%) of fistula complication was noted. The mobility of the veil and the phonation were good in 85.71% and 60% respectively. Articular disorders with nasonation were found in 2 patients (16.67%). Swallowing was normal in 85.72% of cases. Conclusion: The modified Furlow technique is an important contribution to cleft palate surgery significantly reducing the occurrence of postoperative complications. However, the delay of the surgical operation remains a real obstacle for obtaining a normal phonation.

Endoscopic Z-plasty for Treatment of Supraglottic Stenosis: Experience on Nine Patients.

Supraglottic stenosis is a rare type of laryngeal stenosis that is caused by congenital laryngotracheal anomalies, iatrogenic instrumentation injuries, autoimmune disorders, infection, irradiation, chemical or thermal burns, and external blunt or penetrating trauma. The author presents his experience on nine patients using this new endoscopic surgical technique for treatment of supraglottic stenosis. Individual retrospective cohort study, tertiary referral center, university hospital. All cases of supraglottic laryngeal stenosis treated during a 10-year period at a tertiary academic medical center were reviewed. Nine patients with supraglottic stenosis treated with endoscopic uni- or bilateral z-plasty technique were determined and presented. The etiology of stenosis was iatrogenic surgical trauma in seven patients, laryngeal fracture in one patient, and systemic lupus erythematosus in the other patient. Main outcome measures were respiratory function test results, absence of dyspnea on exertion, and decannulation if tracheotomy was present preoperatively. Seven patients with tracheotomy were decannulated 1 month after surgery. All nine patients had adequate airway and were dyspnea-free. Their preop respiratory function test results improved significantly postoperatively (P < .05). For supraglottic stenosis endoscopic surgery using mucosal flaps in the form of z-plasty should be considered within the available surgical techniques. Although this type of surgery is highly successful, it is technically difficult to apply. 4 Laryngoscope, 131:E534-E539, 2021.

Surgical management of post-circumcision webbed penis in children

ABSTRACT Objective To report the outcomes of surgical correction of post-circumcision webbed penis using two previously described techniques: the Heineke-Mikulicz (HM) scrotoplasty and the multiple Z-plasty. Patients and methods A prospective study of children with post-circumcision webbed penis was conducted. The patients were classified into two groups according to the degree of web and the remaining ventral penile skin as to whether adequate or short after circumcision. Group I was repaired by HM scrotoplasty and in Group II the multiple Z-plasty technique was used. Results This study included 86 patients of whom 71 maintained follow-up; 44 (62%) in Group I and 27 (38%) in Group II. The median (range) operative time was 45 (30–55) min in Group I and 75 (60–90) min in Group II. Wound infection occurred in two (4.5%) patients in Group I. In Group II postoperative mild self-limited penile oedema was present in three patients (11.1%). A self-limited scrotal haematoma developed in two (7.4%) patients. Conclusion Correction of post-circumcision webbed penis in children can be done by one of two techniques: HM scrotoplasty in Grade 1 and multiple Z-plasty in Grade 2 and Grade 3, with favourable outcomes.

Modified Z-Plasty for Cervical Spine Myelopathy: A Not-So-Obsolete Method of Laminoplasty

Introduction: It is generally accepted that laminoplasty is a safe and reliable surgical treatment for cervical spine myelopathy (CSM) due to spinal canal stenosis. There are multiple techniques of laminoplasty for spinal cord decompression and most of them require expensive instruments to stabilize the laminae. From 2005 to 2015, we applied the modified Z-plasty (Sakou's technique) for CSM patients in an attempt to reduce the cost of treatment. Materials and methods: This is a retrospective study. CSM patients treated by modified Z-plasty technique were selected. We applied the Sakou’s technique, according to which the laminae will be opened in different directions alternatively. We use the JOA score and recovery rate of Hirabayashi to assess the neurological recovery and the Neck Disability Index (NDI) for the cervical functional outcome. Results: There were 42 patients with the mean follow-up duration of 10 years (5-15 years), male: female ratio of 3:1 and mean age of 61. The mean operating time and blood loss per lamina were 40 minutes and 45ml, respectively. The canal expanding index was 4.2mm (3-5 mm). The mean pre- and postoperative JOA score were 11.1 and 14.7, respectively (p<0.05). For the axial pain, the mean NDI was 18 point with 88% of cases having as good and very good cervical function. For complications, there were 3 cases of C5 palsy with full recovery after one year. Conclusion: Being considered as an old-fashioned surgery, the modified Z-plasty can still provide good clinical and radiological outcomes to cervical myelopathic patients. The absence of hardware such as titanium plates or hydroxyapatite spacers reduces the risk of infection and the cost of treatment. Considering the risk-benefit and cost-benefit ratio, this operation is suitable for low-income patients in developing countries.
