The impairment of the appearance is a major problem for patients with carcinomas of the oral cavity. These patients want to recover their preoperative facial appearance. Some do not realize that this is not always possible and hence develop a desire for further cosmetic and reconstructive surgery (CRS) which often causes psychological problems.
The desire of patients for CRS (N = 410; 26%) has been acquired in this DÖSAK rehab study including multiple reasons such as medical, functional, aesthetic and psychosocial aspects. They relate to the parameters of diagnosis, treatment and postoperative rehabilitation. Patients without the wish for CRS (N = 1155; 74%) served as control group. For the surgeons, knowledge of the patient’s views is relevant in the wish for CRS. Nevertheless, it has hardly been investigated for patients postoperatively to complete resection of oral cancer. In this retrospective cross-sectional study, questionnaires with 147 variables were completed during control appointments. Thirty-eight departments of Oral and Maxillofacial Surgery took part, and 1652 German patients at least 6 months after complete cancer resection answered the questions. Additionally, a physician’s questionnaire (N = 1489) was available. Statistical analysis was performed with SPSS vers. 22.
The patient’s assessment of their appearance and scarring are the most important criteria resulting in wishes for CRS. Furthermore, functional limitations such as eating/swallowing, pain of the facial muscles, numb regions in the operating field, dealing with the social environment, return to work, tumour size and location, removal and reconstruction are closely related.
The wish for CRS depends on diverse functional psychosocial and psychological parameters. Hence, it has to be issued during conversation to improve rehabilitation. A decision on the medical treatment can be of greater satisfaction if the surgeon knows the patients’ needs and is able to compare them with the medical capabilities. The informed consent between doctor and patient in regard to these findings is necessary.
Early on surgeons recognized the importance of psychological variables for coping with distortions in the head and neck area [1–3]. However, the conditions for the implementation of the findings into rehabilitation were not given at that time . Even more not only somatic but also psychological factors for patient satisfaction are important [5–8].
In a multipart work, Kollbrunner determined psychological variables in 2001 [9, 10]. Apart from survival, quality of life (QOL) targeting on dealing with functional and aesthetic impairments became more important in the last 15 years. Nowadays, finally, fundamentals for interdisciplinary care of patients after head and neck surgery are acquired [11–13].
In recent studies, quality of life is defined differently taking disease-specific variables into account (health-related quality of life (HRQL)).
The aim of this study was to define the experience of impairment by asking the patients and emphasizing on aspects of disfigurement and the desire for further cosmetic and reconstructive surgery . Personality traits, psychosocial factors and coping strategies as well as the effects of support, coping and resilience  have been identified.
A particularly important coping strategy is the patient’s endeavour to regain an appearance as close as possible to the preoperative state. This is an illusion, well known to the maxillofacial surgeon but not to the patient. However, there is hope to increase the satisfaction in patients making compromises. Accordingly, the patient needs to be given informative support. Until now, this has hardly been taken up in literature. Few is known describing the importance of scarring and disfigurement of the patient and emphasizing on the importance of quality of life.
The consequence to require further cosmetic surgery has not been researched, even though it is meaningful to maxillofacial surgeons . However, even more significant is the discrepancy between desires of patients to improve their situation and the offer made by the medical and psychological side.
Millsopp  discovered significant differences in the causes for further cosmetic and reconstructive surgical wishes in patients. While 114 (41%) of 278 patients hoped to improve their situation by CRS, only seven of the medical reports portrayed a dissatisfaction with postoperative appearance and only in two cases further CRS was described as necessary.
This should help to rehabilitate the patient after radical surgical removal of oral cancer, to improve the subjective satisfaction and hence the quality of life. Whether another operation makes sense can be determined based on the knowledge of medical data and the patients’ desires. A further aim of this study is to introduce the most significant data needed in the interview between doctor and patient, in order to plan further operations in maxillofacial surgery according to the patient’s needs.
In recent studies, an extended term of life quality (LQ) is being used, describing the connection between surgical techniques and health-related quality of life (HRQL) [17, 18]. Hence, insights on interactions between impairments reported by patients were collected. In addition, an attempt was made to explore the psychosocial conditions or consequences of those impairments [19–26]. At times, no significant differences were found for general LQ, but often for HRQL [22–24, 27, 28].
In this retrospective study, 3894 questionnaires were handed out to German-speaking patients by oncological wards in 43 participating hospitals in Germany, Austria and Switzerland. Of those 1761 returned anonymously in time , 1652 were evaluable. Nine chapters with 147 complex questions gathered demographic data, health behaviour, diagnosis and treatment prior and during the in-patient-stay. Furthermore, the development of the impairments caused by disease and therapy for at least 6 months after surgery was analysed. The questionnaire was developed by the Oral- and Maxillofacial Surgery and the Department for Medical Psychology of the Ruhr-University Bochum and tested for systematic and unsystematic mistakes (Thesis Grochowski & Hendler, 1993 unpublished). Thirty-eight of the 43 participating hospitals returned the questionnaires. Tumour size was specified in 1489 questionnaires. Answers to life quality were not answered in 149 cases. Furthermore, not all patients answered all questions which resulted in minor differences in sample size.
Statistical analysis uses differences calculated by SPSS 22. Occasionally, standard residuals (SR) are mentioned in parenthesis. If significant, differences between groups are emphasized by SRs of ≥2 in crosstabs relating to the subgroups. The calculation of significant differences was performed according to Kruskal-Wallis with a univariate ANOVA second to using the Komologov-Smirnoff test. Significances in correlations and cross tabulations were calculated according to Kendall’s tau b. In addition, linear stepwise regression was used. The results are indicated in boxes.
Wish for further cosmetic surgery
Tumour localization (number of patients counted (n) = 1484
Floors of the mouth (144)
Alveolar gingiva (143)
Other nonspecific sites (145)
There was no significant statistical difference between men (n = 1239) and women (n = 413) (p = 0.12) regarding the wish for CRS.
In contrast, the younger patients aged 14–45 years (N = 131) varied significantly (−0.196** reg. Kendal’s tau-b) as compared with older patients (n = 1459). Patients aged above 45 years seldom wished for further CRS.
The family status was found to be important as single or divorced/separated patients more often had a strong wish for further cosmetic and reconstructive operations (p < 0.003 SR 2.4; 1.8 cross tabulation).
No further significant results were found in between the different educational levels (p < 0.208 cross tab). Even the highest vocational graduation did not significantly influence the wish for further CRS (p < 0.411 cross tab) whereas significantly strong wish occurred in context of the current professional career (p < 0.001 cross tab). Hence, 202 patients who passed the age limit of pension negotiated the wish for CRS more often. In contrast, 66 patients, who were prematurely retired due to tumour operation, were strongly interested in further CRS (very strong SR 3.8 and strong wish SR 1.9). Religious confession was not relevant, but there was a high and significant wish for CRS in patients with more than 500 € loss of income.

Typical chronological process of impairments using the example of appearance
The wish for further CRS was more frequent in patients with bilateral affected localisations (p < 0.001). A notable correlation is also to be found in tumour stage and wish for CRS (p < 0.001): Patients with pT1 staged tumours negated the wish more often than patients with pT4 tumours, who strongly (SR 2.1; N = 20) or excessively (SR 3.9; N = 27) longed for CRS. The correlation of lymph node metastases and the wish for CRS was also highly significant: patients with pN2 stage longed more often for further CRS (p < 0.001) as well as patients with pN3 stage. On the contrary, most patients without lymph node metastases did not want further surgery (N = 659 of 862). Patients who underwent surgery and radiotherapy (N = 608) were determining for the significant difference in wishes for further CRS (p < 0.001).

Figure 1 shows the percentage of patients who longed for further CRS. Even though some patients most intensively longed for CRS (yellow), however, nearly half of all patients do not want any. Last-named belong to the group of older and socially grounded persons as mentioned above. Expectably patients who intensively suffer from impairments had an intense wish for further surgery.

It was asked for normal oral diet as countercheck which reflects the satisfaction of patients not wishing for CRS. Scarring of the face and neck is the main trigger (F = 33,779; p < 0.001) of wishes for further CRS. Therefrom, impairments of the facial muscles lead to dropped mouth corners, and hence, dripping of saliva or drinks is the most important. If facial muscles are unaffected (F = 48,026 in control group), the wish for CRS is much more seldom. Hypaesthesia of the lower lip is also meaningful emphasized by the control group with significantly lower numbers of wish for CRS (p < 0.001). Same is valid for patients without facial or cervical pain (F = 12,378).
Loss of teeth is also of major importance in the development of wishes for further CRS. There is a significant difference (p < 0.001) between patients who lost their teeth and those who did not. The wish for further CRS grows with increasing loss of teeth (especially in the lower jaw).
Test psychological variables
Questionnaire of illness processing (FKV1)
The shortened questionnaire by  showed that patients wishing for CRS (N = 410) and patients not doing so (N = 1155) significantly varied in terms of FKV1. Standard residuals (SR) from Chi-squared test (Pearson) show that these significant differences belong to the fact that patients with strong wish for CRS as well show high values for FKV1.
FKV 2 “depressive illness coping”
Standard residuals illustrate significant differences between the groups of patients longing for CRS (F = 410): Those who strongly wish for CRS as well show increasing depressive coping strategies.
FKV 3 “hedonism”
Here too, minor wish for CRS is related to minor hedonism. Hence, if the value for hedonism increases, so does the wish for CRS. Patient numbers in higher factor values are quiet small. In severe illnesses, thoughts of life enjoyment are seldom.
FKV 5 “mistrust and pessimism”
A strong wish for CRS is related to high levels of mistrust and pessimism.
Locus of control in illness and health (KGG)
Of the three factors, only factor 1 shows significant differences between the groups which varyingly strong wish for CRS (N = 410): Patients with increasing wish for CRS more often react internal.
Loci of control (IPC) by Krampen
Patients with wishes for CRS more often think that others should be helping.
Depressiveness scale by Zersson
The difference between patients without (n = 1155) and those with (n = 410) wish for CRS is statistically significant (p < 0.001, chi-squared). Standard residuals describe the tendency that an increasing wish for CRS comes along with increasing depressiveness.
State trait anxiety inventory (STAI) by Laux
There was no evidence for a statistical relation between anxiety and wish for CRS (p = 0.183, chi-squared).

Questions on future prospects are psychological variables as well. They are related to the evaluation of appearance and cicatrisation and hence with wishes for CRS. Life quality appraisal and its alteration by cancer are both medical and psychological variables. There was no calculated correlation between life quality and overall tumour size 6 months after surgery (p < 0.315, chi-squared). On the contrary, the small group of patients with bigger tumour sizes (pT3) mentioned a higher loss of life quality (p < 0.003). The number of patients with pT1 tumour size was unless larger and stated no significant difference in life quality. Referring to the type of treatment, both variables (life quality now and its alteration by cancer) are significantly different (p < 0.011 resp. p < 0.002).
Psychological assessment furthermore includes the lack of information between physician and patient concerning recurrence. In the questionnaire of physicians, a recurrence was stated 58 times. On the contrary, 272 patients thought they suffered from recurrence and another 106 were not quite sure. There is a significant correlation between the informed consent of surgery, depressiveness (p < 0.001; SR 5.2), fear (p < 0.001) and life quality at diagnose (p < 0.001) of the patient. Those patients who stated to be well informed mainly belonged to the group evaluating a high life quality. Badly informed patients evaluated their future to be more hopeless (p < 0.001; SR 5.6). They suffered more often from problems in relationships (p < 0.001; SR = 3.8) and frequently avoided public visitations (p < 0.001; SR = 3.3).
An important role is played by the question for further CRS in terms of rehabilitation after radical surgery of oral cancer . It is well known that the impairments, deficits and psychological variables are due to this fact. Relations in between those variables are nevertheless inadequately researched and practically implemented . Most oral and maxillofacial surgeons know that most patients do not want to undergo further CRS. However, literature did not describe yet that this population can be as large as 74%. This is maintained among others by the tumour localisation which is contrary to the fact that 90% of our patients had no further CRS. After all, 26% had a strong wish for CRS. This might be explained by patients’ insecurity evaluating medical facts, which can be seen in terms of knowledge on relapse. Physicians diagnosed a relapse in 58 patients, but 272 patients believed to suffer relapse, and another 106 were unsure. A total of 80% were varyingly worried about relapse as Campbell emphasized . Hence, there is an information gap, which could be closed by improving the physician-patient consultation.
No difference was shown between gender and wish for CRS in this survey. Family status on the contrary was important: widowed, divorced and separate as well as single patients mentioned a stronger wish for CRS than those bound to families. Older patients resigned more often than younger ones. Already discussed in literature patients with strong wishes for CRS stated a loss of income more often than those without wish for CRS [7, 36, 37]. The importance of this aspect is emphasized by the fact that loss of income got incorporated in the questionnaire by Rogers .
Concerning life quality (LQ), cicatrisation and facial distortion are of major importance, which is conveyed in our study and in literature [3, 8, 16, 35, 39]. Nevertheless, several examiners did not find a reduced life quality in comparison to normal population or other cancer types . Which psychological mechanisms are due to this fact should be urgently resolved, since additional particularizing questions indicate the opposite .
Our survey on 19 impairments affirms the suspicion that questionnaires on life quality do not describe the full range of psychological conditions. All 19 impairments are highly correlated to life quality. They change during the period of time after surgery and not only in patients with oral cancer. Hence, appearance itself follows the typical exemplary course of impairments. Pre-operatively, there are no grievances; shortly after surgery, discomfort is at its highest level, and 6 months post-operative values are decreasing. This course of discomfort is often reported in literature for example by Markkanen-Leppänen .
From a list of 19 impairments, each impairment differed significantly in its strength regarding the wish for CRS. As prospected, the most important impairments were appearance and mandibular mobility. Kamstra et al. and Devine et al. mentioned mandibular mobility as main factor [44, 49] as well as Hahn et al. . Furthermore, cervical mobility, articulation of speech and mouth opening are meaningful.

Medical data implements that the importance of surgery, radiation, dissection and reconstruction is meaningful in developing wishes for further CRS but inadequately researched. And yet they are important preconditions for optimal rehabilitation. There will be no sufficient, satisfying result if there is a great gap between patient’s expectations and medical possibilities . Only an extensive survey among a high number of patients is able to describe the network in between each and every factor. One hundred twenty-five patients were operated once at time of survey. In total, 410 wished for further cosmetic operations. It can be assumed that many of those taking a medical point of view were in no condition for further successful surgery. This fact has to be discussed with the patient, so he/she can feel well treated and life quality remains stable [11, 54, 55].
Among psychosocial variables, the age of patients is important for the wish for CRS. Younger ones more often longed for CRS , and additionally, the chance of survival is higher as Goldenberg et al. confirmed in 2009 . After pension, the need for CRS is decreasing, unless it is a premature pension due to the diagnosis of cancer. In this last named case, there was a very strong wish for CRS. Furthermore, patients without partner more often wished for CRS. Some literature describes the coherence of wish for CRS and impairments as, for example, nutrition. Liquid diet increases the wish for further CRS [58, 59]. Equally, pain and hypaesthesia are important for the wish for CRS. Both strongly influence the description of the emotional and functional situation by the patient, yet we were not able to prove a relation to the wish for CRS.
Nevertheless, there is a link to researches on cosmetic surgery in general and on orthognathic surgery. Those surveys show that questions on psychological problems are important for the satisfaction of patients with surgery all the same [5, 60–63]. Hence, we assume that psychological factors play a similar role in patients who underwent surgical treatment of oral cancer. There is a high number of possible measuring tools . The clarification is essential by evaluating the psychological situation of the patient and hence discussing and improving the outcome.
Depressive mood, depressive illness coping and problem analysis are related to further wishes for CRS and hence should be acknowledged by the physician and discussed with the patient. Also, future expectations and evaluation of life quality are of major importance [64–69].
As early as 1980, Sela and Lowental noticed that cancer patients require more than a well-fitting prosthesis for successful rehabilitation . This belief grew throughout the years, but is not yet always realized. Patient management is complicated and depends among others on the patients’ willingness to answer psychological questions [28, 71, 72]. If especially educated nurses or physicians conduct the conversation and psychology is not pronounced, patients may not have those problems. It is furthermore to be examined if patients do understand that their wishes may not be fulfilled all the time and a compromise is to be taken [73, 74]. The ability to get back to work without facial distortion belongs to this set of issues, equalling a signup of full rehabilitation.
The wish for CRS depends on diverse functional psychosocial and psychological parameters. Hence, it must be issued during conversation to improve rehabilitation. A decision on the medical treatment can be of greater satisfaction if the surgeon knows the patients’ needs and is able to compare them with the medical capabilities. The informed consent between doctor and patient regarding these findings is necessary.
