Background: Thyroidectomy is a commonly performed procedure with large centres performing thousands of thyroid surgeries per year. The traditional Kocher mid-cervical incision has been the standard approach to thyroidectomy since the late 1870s with predictable results. The introduction of minimally invasive and remote access techniques seeks to reduce the morbidity of a mid-cervical scar incision.

Methods: Ninety-five [95] patients who underwent this approach over the thirty [30] months period from January 2015 to July 2017 were administered the validated Patient Scar Assessment Questionnaire and the collected data analysed.

Results: Forty-eight [48] patients, (50.5%) met inclusion criteria and provided responses with a mean time since surgery of 18.9 months. There is a high level of satisfaction with 91.7% of patients in the study having scores consistent with scar satisfaction after conventional thyroidectomy. While patients were satisfied with the appearance of their scars, a majority of patients (n=28, 58.3%) were at least slightly conscious of their incisions, with more than 10% of patients (n=5) reporting significant levels of self-consciousness. Patients of Mixed race were found to have slightly elevated scores on PSAQ compared with IndoTrinidadian and AfroTrinidadian races (P=0.002 and P=0.006).

Conclusions: Most patients were satisfied with their scar results in the years after thyroidectomy. Despite the high level of satisfaction, a majority of patients are self-conscious about the presence of a mid-cervical incision. Further research is needed to elucidate causes and the effects of this finding.

The conventional cervical incision, or Kocher incision, has been the traditional approach to thyroidectomy since it was first introduced by Theodore Kocher in the latter part of the 19th century (1). He mainly used the collar or mid cervical incision, as he recognized that this approach gave the best cosmetic results.

Since the development of minimally invasive techniques, there has been a drive to apply these approaches in almost all specialties of surgery (2). Thyroid surgery has not been an exception to this, with the results of decreased hospital stay, post-operative pain, and improved patient satisfaction (3-5).

Even though there is increasing utilization of these techniques around the world, these facilities are not readily available in the Caribbean setting, and the Kocher incision remains the mainstay of surgical approach to the thyroid gland (6-8).

The purpose of this study was to determine if patients are satisfied with their surgical scar after conventional thyroid surgery incision.


Patient sample

Approval for this study was obtained from the Bio-Ethics Committee of the South West Regional Health Authority (CCE0008). The study sample included patients who underwent a total or hemithyroidectomy at the San Fernando General Hospital, Trinidad, by the Otolaryngology and Head and Neck Surgical Team. Ninety-five [95] patients were identified by review of operative records from the time period January 2015 to July 2017.

Exclusion criteria were patients who were under the age of 18, underwent additional procedures during surgery requiring extension of the incision, complications of surgery requiring reopening of the incision, wound infection, treatment for hypertrophic or keloid scar formation with steroid injections, and reoperation after initial surgery.

Patients were contacted via telephone and verbal consent was obtained before administration of the validated Patient Scar Assessment Questionnaire (PSAQ) was done by a standardized protocol. Forty-eight [48] patients were contacted and agreed to complete the questionnaire.

Survey instrument

The survey instrument was divided into two [2] sections A and B. Section A; included patient demographic and surgery related features: sex, age, race, time elapsed since surgery, type of surgery and histopathology report. This information was extracted from review of the patients’ medical records.

The second part (Section B) of the survey instrument, contained the questions pertaining to patient satisfaction and scar consciousness. The PSAQ is a validated patient scar assessment tool (9). It consists of five (5) domains or subscales: Appearance, Symptoms, Scar Consciousness, Satisfaction with Appearance and Satisfaction with Symptoms. Of note, the Symptoms subscale is the only domain not yet validated by the instrument creators as applicable to linear scars.

The PSAQ was designed in such a way as to allow each domain to operate independently of the others and therefore the use of only 2 of the 5 subscales can be employed without affecting overall validity. Three of the five subscales were utilized in order to reduce the duration of the interview and to increase patient participation. These were: Consciousness, Satisfaction with Appearance and Satisfaction with Symptom scales.

The Consciousness subscale consists of 6 questions, the Satisfaction with Appearance and Satisfaction with Symptoms consists of 8 and 5 questions respectively. Patient responses are scored on a Likert type scale with a point range of one to four. A score of one corresponded to an answer of patient being very satisfied and four being very dissatisfied. Scores were summed to give a total score for Consciousness of 24 (range, 6 to 24), Satisfaction with Appearance 32 (range, 8 to 32) and Satisfaction with Symptoms 20, (range, 5 to 20). A total maximum overall score of 76 was possible (range, 19 to 76). Higher scores therefore corresponded to decreased patient satisfaction with cosmetic result.

Surgical technique

The conventional thyroidectomy incision was made in a skin crease typically placed 2 cm above the sternal notch. A standardized skin closure using subcuticular interrupted vicryl sutures was used for patients included in the study. Passive drains were used for all patients and these were inserted through the surgical incision site.

Statistical analysis

Data analysis was conducted using SPSS version 25 software. One-way analysis of variance (ANOVA) and independent sample t-test were utilized to determine if demographic or surgery related features were significant factors in predicting patient satisfaction with scar outcome.


Patient characteristics

Of the 48 survey participants, 44 (91.7%) were female and 4 (8.3%) were males. The mean patient age at the time of surgery was 51.08 (±10.98) years with the youngest participant being 29 years old and the oldest 72 years. The ethnic distribution of our patients was mainly IndoTrinidadian—27 patients (56%) followed by AfroTrinidadian 14 patients (29%), and 7 patients (15%) identified themselves as being Mixed Race.

The median time since surgery was 18.5 months. The study sample included 35 patients (72.9%) who underwent total thyroidectomy and 13 (27.1%) who had hemithyroidectomy performed. Twenty-eight surgical specimens were diagnosed histologically as benign thyroid disease and 10 were diagnosed as malignant. The validated results for 10 surgical specimens were not available. This data is summarized in Table 1.

Results of PSAQ

The mean scores for patients in the Consciousness domain was 7.8±2.7 (mean ± SD), in the Satisfaction with Appearance 10.4±3.0 and Satisfaction with Symptoms 5.9±1.7. While overall the scores were relatively low, 5 patients (10%) of the study population had elevated scores in the Consciousness subscale that indicated that there was a significant degree of self-consciousness with regards to the presence of a neck scar (Figure 1).

The mean total PSAQ score was 24.43±6.4, out of a total maximum score of 76, and scores ranged from 19 to 41. A score of 38 or greater was considered indicative of patient dissatisfaction with scar outcome. Based on this cut-off point, two patients were deemed as having dissatisfaction with surgical scar (Table 2). The distribution of patient PSAQ scores is seen in Figure 2.

Results of ANOVA and independent t-test

In the evaluation of patient race, ANOVA analysis detected a significant difference in the overall PSAQ scores of patients of Mixed Race having an average score that was higher compared to patients of IndoTrinidadian and AfroTrinidadian race, P=0.006 and P=0.002 respectively.

However, ANOVA and independent t-test analysis did not detect any significant difference in patient scores based on patient age, gender, time elapsed since surgery, histology of specimen, or type of surgery performed.


Incisions associated with thyroid surgery have long been perceived as a source for cosmetic concern amongst surgeons because of its location of the prominent anterior aspect of the neck. This has fuelled the drive towards minimally invasive thyroid surgery, robotic and laparoscopic associated techniques, and scarless thyroid surgery (10). However, there remains much controversy with regards to evidence to support that this view point is shared by patients who undergo thyroidectomy.

Our study assessed the satisfaction of patients post conventional cervical thyroidectomy. The findings of this study corroborate those of others which found that overall patient scar satisfaction after conventional thyroidectomy incision is very high (11-13). In our study it was observed that only two patients were found to have scores that indicated that there was a significant level of dissatisfaction with surgical scar. Notably, their scores were only marginally elevated.

Of note, there were five patients who indicated from their scores in the consciousness subscale that they were self-conscious about their scars. This showed there is a subgroup of patients who although they did not objectively identify any problems with scar symptoms or appearance, were still conscious of having a scar on their necks.

A significant difference in patient scar satisfaction was demonstrated based on the race of patients. Patients who identified themselves as being of Mixed Race consistently gave responses to the PSAQ that were statistically significantly higher compared to other racial groups. It is unclear if these higher scores were due to an increased predisposition to the formation of hypertrophic scar or wound healing idiosyncrasies.

Multiple other studies have demonstrated difference in scar satisfaction based on patient gender, with female patients generally having a greater degree of dissatisfaction compared to males (11,14). This was likely not demonstrated in this study because of the small number of male participants.

The study also did not demonstrate any statistical difference in patient satisfaction based on the patient age, benign vs. malignant histopathology, type of operation performed (hemi or total thyroidectomy), or time elapsed since surgery.

The method used for closure of wounds for patients in this study was interrupted suture with subcuticular vicryl. Literature review of studies indicate that the method of closure chosen with regards to absorbable and non-absorbable sutures dose not significantly impact patient perceived outcome of the scar (15,16). Factors that have been shown to optimize scar outcomes are the application of cosmetic principles such as marking of patients in the upright position, avoiding elevation of subplatysmal flap to decrease postoperative neck edema and healing times, and avoidance of drain usage where possible (2).

While most patients were satisfied with their scar overall, a very high percentage of patients were at least somewhat self-conscious about their incision. This is consistent with recent reports suggesting that concerns about cosmesis are the most common of all post op adverse events associated with thyroidectomy. If a majority of patients are concerned to some degree about cosmesis, the role of “scarless” surgeries would therefore be directly related to how safe, effective, and available such procedures may be.

The benefit of minimally invasive techniques in thyroidectomy is centred around the absence of a cervical incision. Possible additional benefits of post-surgical recovery time and improved pain exist, but are ancillary. Because these procedures are generally more expensive, they are not always available in the Caribbean health care systems (17). Even with the consideration of factors such as decreased time of recovery and shorter periods before return to work that allow for improved overall population productivity, the cost benefit of investing in these technologies may be beyond the means of many Caribbean health providers at this time.

The role of the cervical incision on overall health is poorly defined in the literature (3,7,12,18-21). It has been demonstrated that patient concerns about thyroid surgery tend to be related to concerns of the possibility of malignancy within the thyroid nodule being removed, and complications from surgery such as voice change (14). Although these above factors were beyond the scope of this study there may also be a consideration of level of education, marriage status, parity and socioeconomic factors that may play a role in patient satisfaction and perceived scar outcomes (13).

Based on a PubMed search of the literature, this is the first study of this type to assess patient satisfaction and perception of scar after thyroid surgery in Trinidad and also the English-speaking Caribbean. The study had the advantage of examining patient scar outcomes using a validated questionnaire and also of following patients over a longer period of time postoperatively.

The limitations of this study included the small sample size of only 48 patients. It is therefore to generalize obtained results. The data collected was also self-reported over telephone by patients and did not have an objective component such as scar length or observer assessment as would be considered in other scar assessment tools (22,23).


In conclusion, this study demonstrates that there is overall a high level of satisfaction amongst patients post conventional cervical incision for thyroidectomy, despite the fact that most patients are somewhat self-conscious of their incision even more than a year after surgery. The role of remote access thyroid surgery is therefore directly related to how much more costly it is to patients, both with regards to finance, but even more with regards to complications, effectiveness and availability. Patients of mixed race were found to have a slightly elevated scores on PSAQ compared with other race groups in the study. The role of minimally invasive and scar eliminating surgical approaches in the Caribbean should be evaluated for cost-effectiveness of application in the region.
